Libya Government

c/o Libyan Liaison, Mr. Sofian,

2600, Virginia Avenue, NW
Suite 705, Washington DC, 20037, USA


Dear Dr. Taher E. Jahaimi


Please consider this letter as a formal introduction. Our corporation’s innovative manufactured home design, 70-years of construction and 25-years of plant experience between the owners illuminating our expertise in commercial, agricultural and residential construction. Our web site is (no longer active) and requires a username  (investors) and pass word (474849) in order to access our home designs located in the residential steel framing section, while log in occurs in the investor section.


With the urgent need of durable, inexpensive and energy efficient homes utilizing steel framing fastened in ways to the concrete slab and metal components that secure the building and roof in way’s presently not even explored, our homes we believe may be of interest to you as the Minister of Planning for the Libyan government. Our homes will exceed 120 mile an hour winds and our innovative cement footings and slabs can be built in the sand and will not erode during a flood. Assorted home views are attached


Our chosen facility for our Manufactured Insulation Injected Panelized Wall Steel Framed Home distribution facility is the Jourdan Road Intermodal Park Facility next to the port of New Orleans, owned by Allan B Colley, President, Dupuy Storage & Forwarding, LLC, 4300 Jourdan Road, New Orleans, La 70126 U.S. Since 1936, Dupuy Storage & Forwarding has been a respected name in the warehousing industry.


Our second chosen location for our manufacturing plant is the Port of West St. Marry, requiring St. Mary Parish to build a 280’ by 1,016’ facility with accompanying buildings illustrated in the investor section under Large Scale Plant Drawing of our web site or view the attachment. Port of West St. Mary, P.O. Drawer 601, Franklin, LA 70538 has 300-acres available for corporations involved in manufacturing, bringing jobs to the Parrish.


We have workers compensation insurance company prepared to insure our work force of 339, graduating to 928 within 16-months, arranged through B& k Harry Kelleher & Co., INC., President, Pat Kelleher.


In an interview posted on United World web site, you expressed there were two kinds of budgets in Libya; one is for salaries and current expenditures (which is under the Ministry of Finance), the other is for investment, which falls under the Ministry of Planning.

With so many jobs being taken by non-Libyans while young nationals remain unemployed or under-employed hoping for government jobs in your country, we believe we have a viable solution, providing 720 square feet homes on a manufacturing scale of 480 homes per month, graduating to 960 and then 1,400, totaling 14,400 homes in an 18 month production cycle within six months of project commencement.


With your countries need of bout 450,000 new housing units over the next ten years or so, we would consider equipping a second Plant at the port of West St. Mary, Louisiana.


Our manufacturing sales cost is $31.00 per square feet plus shipping and handling to Libya in 40’ open containers with tarps, delivering every home component with the exception of windows purchased by us in your country.


Floor tile, kitchen/bathroom sink/cabinets and interior plumbing, shower and toilet are not included in this price, yet paneled exterior/interior wall in the bathroom would have cement board rather then dry wall if you elected tiled showers rather then shower stalls.

In order to reduce shipping cost, requiring more containers and a larger work force on a manufacturing scale, kitchen and bathroom cabinets, sinks, toilet and associated plumbing is not included in our square feet pricing of our manufactured homes.


Financing through Ex-Im Bank provided buyer had 15% down, could include aforementioned as well as the cement slab since our concrete receivers/connectors must be installed to include erection and finish labor cost. Exterior walls are panelized with insulation injected, Cemplank exterior James Hardy wall board and dry wall for out side wall interiors, all steel components (roof metal, interior walls built in the plant, hat channel, trusses and fasteners, wall bolts, 46 concrete connectors/receivers connected together in four sections, metal doors and interior ceiling hat channel) and dry wall for interior ceiling, bedrooms/bathroom, electrical package with race ways in the exterior walls for electrical wire with junction boxes and out lets in the exterior walls, to include plumbing in the kitchen exterior wall, trim, dry wall texture/tape, primer and finish paint.


Complete and easy to understand erection methods, assistants in developing a Planned Community, Concrete footing and slab construction would be in introduced to your courtiers engineers, contractors and carpenters.


We would fly aforementioned to our chosen plant, supporting your planned communities with foreign steel experts on site until such time your work force gains the experience to construct 480 homes per month, preceded by cement footings/slabs, with concrete connector/receivers installed during the cement poor, fastening our homes panelized walls to the slab.


Your wide-ranging credit program that was launched to help create jobs in the private sector and to provide soft loans to help young people build their own new homes would off set erection cost as thousands of those desiring a home could be assembled to erect our steel kits in accordance with various Phases discussed in detail on our web site.


Your programs to increase production capacities in steel and cement to facilitate expansion in constructions with us onboard would give you a wealth of roll metal and metal forming contacts and engineers.


While you’re local market may not be flexible enough or resourceful enough to provide the requirements of large construction programs, as a foreign specialized corporation we would be most willing to participate if invited.

General Peoples Committee of FiancéÇÞÊÑÇÍ


Mr. Jahaimi, I am the designer of our Manufactured Insulation Injected Panelized Wall Steel Framed Home process and am partnering with experts in various fields of roll metal, metal forming and insulation injected processes, the latter not presently available to any corporation in the U.

Introduction of our steel SEALECTION™ 500 spray foam injected stud panelization Homes


New Home Generation, Inc. is a newly formed corporation, comprising of Board Members and Corporate Officers with over 70-years of construction experience and 25-years of Boise Cascade Plant experience.


Our goal is to remain at the forefront of pre-panelized load-bearing metal stud walls with SEALECTION™ 500 spray foam injected between the studs, introducing a manufacturing process capable of producing 1,400 720 square feet homes per month, with a special emphasis on product quality and production efficiency.


Our Home Manufacturing Design Aim


Our aim is to create value for customers and shareholders. We will do this by aggressively growing our steel SEALECTION™ 500 spray foam injected stud panelization Homes in markets where we can establish a differentiated competitive position using the skills of our people and our unique technology.


We see opportunities in new markets where we can create and sustain Homes Sales for years to come.


Realizing the importance of quality assurance systems within the home building industry, new Home Generation, INC. Home design on a manufacture scale, introduces a residential home design with a roof membrane system that will exceed the most recent version of ASTM D3161, modified to reflect 110 mph fan-induced wind speeds or Miami-Dade protocol PA 107, be certified to meet minimum wind speeds of 110 mph provided steel components be installed per manufacturers’ specifications.


An insulated under lament material will be used on the roof, applying the 16” to 18” metal roofing panels atop the insulated under lament laid atop 16 gauge hat channel on 9” spacing. The bottom chord of the trusses will also have hat channel on 16” spacing. Hurricane straps or other hardware that connect the roof to the walls will be installed with the proper number and type of crews and bolts to include 30’ top tracks securing the 15’ walls together, accompanied with 7’ 4” flat vertical wall seem/joints and 24’ horizontal flat steel fasteners securing end walls to the gable prefabricated 6” wide stud framed insulation injected paneled truss.


Special vertical vinyl under lapping/over lapping trim will seal our Homes Hardy Board seem/joint atop flat 4” wide 3/16” thick wall fasteners to existing studs doubled up on all ends of walls developed during our Research and Development months in conjunction with a leading manufacture of vinyl trim. The gable wall/truss 24’ fastener with gable end truss brackets attached will also have horizontal vinyl trim. In order to accommodate doors in the living room and kitchen in our centering of walls atop the concrete/receivers every 2’, doors have been off set. Engineered specifications will compliment our present design using rational analysis based on wind loads calculated according to ASCE 7-98, using a Basic Wind Speed defined by ASCE 7-98 but not less than 120 mph.


In order to satisfy customers consistently, we have incorporated in our home design a planned, systematic and documented approach to quality, with further emphasis placed on concrete/receivers for the walls of our Homes, thereby anchoring to the concrete slab.


Working with our Buyers and designated Planned Community


Operating effectively across international boundaries would require direct association with pontential buyers, their contractors, our field carpenters and corporate management.  Implementation of a systematic and ingenious concrete/receiver installation within the cement or footings, simple erection instructions, training from field carpenters and Senior Construction Expert, would be critical to developing successful strategies and implementing them decisively. Home erection videos and instruction booklet would compliment steel erectors along with field carpenters able to train others. Utilizing separate crews for various construction Phases will result in maximum Home erections based on number of crews available, thereby increasing sales of homes when potential buyer’s contractors work force increase their productivity and or bring on additional crews.


Our system of Loading walls into open containers up right with concrete tilt up inserts built into the top track will allow walls picked up at one time, entering the container with the walls a foot off the ground in accordance with Home floor plan by a Bridge Crain with a hoist 10’ off the ground traveling in a designated area with others their own area, the quantity necessary scheduled for Phase.


At the job site walls are unloaded from either a flatbed semi truck trailer by a Crain lifting four walls at a time or from the ground in any terrain provided a four wheel drive forklift with a extended and 6” sliding mask is available, unloading from the side of an open container, the latter included in the Home Sales if necessary to the quantity necessary.


The walls would be placed on the concrete slabs and then directly in the receiver/connectors, while two walls will hold each other up.




We see growth in means of increased Home Sales to potential Buyers and while there is a world wide need for inexpensive, sturdy, energy efficient 720 square feet Homes, as the only manufacture of prefabricated steel SEALECTION™ 500 spray foam injected stud panelization Homes, we would be well positioned.


Future Direction


The markets for prefabricated steel SEALECTION™ 500 spray foam injected stud panelization Homes are large and profitable.


Our unique Home manufacturing process would increase Home production by 480 Homes within periods of six months to a maximum of 1,440 Homes monthly with a work force of 928 during day shift, commencing Phase 3 with a Production Work Force of 339, Phase 4 with an increase of 311 and a final increase of 278 personnel during Phase 5, with 55 Management and support staff, totaling 983. It is our intention to aggressively grow demand for our product and introduce our homes domestically. Ex-Im Bank financing provided Buyer and Exporter can meet required policy banking conditions would be an added benefit and is discussed in detail within the confidential Buyers on line tour of our Home designs not available for public viewing. Our Home Page design drawings are generic.


Beyond the Future


Swing and Night Shift would include increased management and work force, yet increased cars; possibly increased container shipping might strain the existing plant logistics, thereby making it necessary to build a new plant at another location within 100-miles of our port chos

Growing and Developing Markets for Galvanized Steel

Exciting growth opportunities for flat rolled coated products, both in traditional markets and in new markets, are the focus of AISI's Market Development efforts and of the North American Steel Framing Alliance. Growth potential for all flat rolled steel markets exists through expansion of existing markets and development of new markets and innovative applications. Targets are the commercial roofing and framing markets, steel utility poles, corrugated steel pipe, automotive market, and residential roofing and framing markets.

The residential framing market is one of the largest new opportunities for galvanized sheet steel. It is a waking giant, representing a potential new market of 15 million tons of galvanized sheet per year. To put that number into perspective, currently the total annual capacity for coated sheet steel in North America is 26 million tons. Annual US consumption of hot-dipped galvanized sheet steel has been at about 16.8 million tons since 1993. Where does this go? About 38% is consumed by the automotive industry, 25% is consumed by steel service centers, and another 16% is consumed by the construction industry. Today, the construction markets, and in particular the residential framing and roofing markets, are the fastest growing users of galvanized sheet steel.


This article was written and published in national trade media by NUCONSTEEL personnel. The authors are widely regarded as among the most knowledgeable and experienced in the light gauge steel industry.


Design for a Cold-Formed Steel Framed Manufactured Home: Technical Support Document (March 2002, 82 p.)


The use of cold-formed steel in the structural system of residential construction has taken hold in some site building markets but potentially offers far more value to the manufactured home industry. Steel is lightweight, fireproof, vermin resistant, dimensionally stable (not subject to material decay, warping and twisting and shrinkage) and can be fabricated to a wide range of shapes and sizes with virtually no material wastage. There are additional factors that suggest the industry ought to consider options to wood as the basic structural building block. Foremost among these are the uncertainties associated with future wood resources and the historic price fluctuations that at times have made wood more expensive than steel. Even if steel proved to be less attractive than wood in the short term, as a future alternative material, steel shows considerable promise. The report summarizes the results of the first phase of a multiphase effort to assess viability of substituting steel for wood as the structural skeleton of homes built under the HUD manufactured home standards. The research focuses mainly on structural design, thermal conductance, and cost issues.

Prefab Building Construction


Up to 90% of the work in creating a modular building is done at the factory, including both the interior and exterior: walls, roof, doors, wiring, carpeting, and more. They're built using standard construction materials like lumber and drywall. The mostly-finished building is then delivered and installed at your site.

In contrast to the modular building process, only the components of steel buildings are fabricated at the factory. Steel beams, sheeting, and fasteners are delivered to your site, and the building is pieced together on site. Any interior work is done after the construction is complete.


Because of the specific skills needed to assemble modular buildings, you'll need a specialized contractor to do your on-site work. Steel buildings are delivered with detailed blueprints and require only general construction skills to assemble - any qualified general contractor should be able to handle the job.


Both modular and steel prefab buildings drastically shorten construction times over traditional buildings. Modular buildings require much less work to be done on site but take longer for the factory to produce. From initial order to completion, total construction times for comparable structures can be fairly similar. However steel buildings are often simpler structures with less finishing work; in practice they tend to take less time.


Prefab Building Sizes


Because of the construction methods involved, steel buildings and modular buildings have very different size profiles. Modular buildings usually have interior ceiling heights of no more than 8', because they have to be transported on the road. Steel buildings, in contrast, are commonly built with interior heights of 30' and up.


The net result is, if you’re prefab building is to enclose large, open spaces, like a warehouse, barn, hangar, or garage, you need a steel building, not a modular building.


Similarly, each section of a modular building has to be between 10' to 18' wide and 36' to 76' long, for transportability. However, the construction methods involved allow them to be seamlessly assembled into much larger buildings, up to tens of thousands of square feet. Modular buildings can also be stacked on top of each other to create buildings up to 3 or 4 stories high.


Steel buildings can be as small as a 10' x 20' shed or as large as 150' wide by nearly unlimited length with no interior columns. To get over 150' wide, steel buildings require interior columns at regular intervals. This type of construction is very confusingly called a "modular" steel building, but don't get thrown off. The "modules" are simply the spaces between each column - they're built in the same fashion as other steel buildings. Steel buildings can also have multiple stories, but it's much less common.


Prefab Building Customization


Modular buildings generally offer more flexibility in design than steel buildings. With steel buildings, you choose the size, location of doors and windows, and pitch of the roof, but the building itself is just a box. Modular buildings provide more flexibility for customization, which can be important if your lot is oddly shaped or your intended use of the building calls for a particular layout. Additionally, modular buildings typically come with finished interiors - steel buildings may include interior wall panels so you're not looking at insulation or bare metal, but most interior work will be up to you.



Modular buildings can range from $35 to $100 per square foot. The range is so large because the price includes finishing: a basic classroom or office will usually fall on the low end of that scale, while a fancy retail outlet with lots of customization will be more expensive.


Steel buildings are less expensive, often because they are less finished on the inside. Very basic steel buildings can be put up for as little as $16 to $20 per square foot. More finished metal buildings are usually $20 to $30 per square foot, and extensively customized buildings with brick facades, unusual shapes, or complicated construction can reach $40.




Both steel and modular buildings boast improved appearances in recent years. Modular buildings can be constructed with wood, steel, brick, or stucco exteriors, and steel buildings can add facades using the same materials. However, if the appearance of your buildings is important, modular buildings provide more flexibility at a lower cost than steel.


Office trailers


You should also consider if an office trailer is all you need. Office trailers - also known as mobile offices - are the cheapest and most temporary type of pre-manufactured building. They're a familiar sight on construction lots across the country. They range in size from 8' x 20' to 12' x 60' (a "singlewide") and can combine into double, triple, or larger groups.


Office trailers are almost always leased: they're a temporary solution, not a permanent structure. They have few options for appearance and customization, but they are the cheapest and fastest way to add office space to a job site. They are delivered ready for use, with wiring, heating/air conditioning, and even basic furniture already installed. They're also the only realistic choice if you want a very small building, under around 800 square feet.


Basic Rigid-Frame Steel Building


A typical price for basic rigid-frame steel building (steel only/non residential) is between $16 and $20 per square foot. This includes steel materials, delivery, the foundation, and construction. A more finished building may be closer to $30 to $35 per square foot, and extensively customized buildings with brick facades, unusual shapes, or complicated construction can reach $40 per square foot or more.


Materials alone can cost $5 to $15 per square foot. This varies according to size: small buildings cost more per square foot. Materials for a 250' x 120' church building might cost $240,000, or $8/sq ft, while a 20' x 20' garage might cost $6,000, or $15/sq ft.


Foundation costs are fairly standard, usually $4 to $8 per square foot for poured concrete. Remember that GCs may include this cost in their proposals, but brokers and manufacturers of metal buildings definitely will not.


Basic Rule for Estimating the Cost of Steel


You can also use a basic rule that is based on weight rather than linear feet—for slab-on-grade homes, you can estimate the cost of the steel you need by multiplying the square footage of the house by seven pounds per square foot. Then, multiply this number by $1 per pound to get the approximate retail cost of steel.

The following example represents steel material only that includes metal trusses/hat channel above and below trusses, roofing and foundation anchoring:


•              720 SF for the house at 10 lbs/SF = 7,200 lbs

•              Total weight for the house is 7,200lbs or 3.6 tons

•              7,200lbs at $1.00/lb = $7,200.00 for the steel framing material


Steel framing differs from wood in that most of your cuts are made ahead of time following directions from a cut list. To make a cut list, you need to count the number of members needed and list their respective lengths, always ordering 10 percent extra so that you don’t run short of materials. Manufacturers have an added savings of up to 10 percent because of lower losses from vandalism, theft and bad weather. Once you have a detailed cut list, our roll-former, after determining the price sheet can calculate the cost (cost is typically given in pounds per foot). Discounts are available with volume and we intend to secure the best available discounted price “based on volume” for home components as is possible. When possible we will purchase from local businesses provided there cost is close to other businesses out side Louisiana.


Introduction of the


The building industry is now forever changed because of light gauge steel framing.


At least half of the manufactured homes being sold are either double-wide or triple-wide, ranging from about 1,100 square feet to as big as 2,700 square feet.


Builders and contractors have found the dramatic reduction in assembly time and less material waste have saved them time and money. They have also found that steel framing ensures a stronger and higher quality construction.


Many builders have found the economical benefits of roll forming their own steel studs when other builders have been finding success with steel stud panelization.


The panelization process starts by roll forming steel studs for trusses or wall panels inside a factory. The steel studs are assembled directly in the factory and then the trusses and walls are shipped to the jobsite where the building is erected.


Residential steel framing utilizes cold-formed steel members for walls, floors, and/or roofs.


The framing members are C-sections with standard dimensions similar to wood framing studs.                                                                                                                                                        

Steel framing can be a cost effective alternative to wood framing.


Steel mills produce galvanized sheet steel, the base material for steel members. Sheet steel is roll-formed into shapes used for framing.


The sheets are zinc coated (galvanized) to prevent corrosion.


Although there are a variety of shapes available, the primary shapes used in residential construction are the C-shape stud and the U-shaped track.


Framing members are generally produced in thickness of 12 to 24 gauges with 3-½ and 5-½ widths.


Manufacture of steel framing members adheres to strict tolerances, which results in consistent strength, straightness, and dimensionally stable members.


Steel framing provides excellent design flexibility due to the inherent strength of steel, which allows it to span longer than wood, and also resist wind and earthquake loads.


Architects and builders, wanting to reduce dead load, construction time and costs, are more frequently utilizing light gauge steel stud framed panels with any of several different finish materials to construct exterior walls on their building.


Remarkable cost savings are possible when the steel stud panels are fabricated off the job site.


Foundation Concrete Connectors or Receivers


NAHB Research Center can give New Home Generation Inc. an evaluation of our concrete tie system and working in conjunction with Simpson Strong-Tie and Benner-Nawman, Inc., a cost effective concrete/wall tie down design will emerge allowing the ties to serve as receivers for our paneled walls, focusing on load wall to floor distribution from the trusses.


Selected management, Operators and Field Carpenters will under go the necessary training at Southeast Training Centers, Jacksonville, in order to learn  the importance of quality assurance systems within the home building industry, the NAHB Research Center developed the National Housing Quality (NHQ) Program to help build consistency, efficiency, and continuous quality improvement in building practices.


Simpson Strong-Tie Inc. is committed to training customers on the proper specification, installation and inspection of structural system solutions. Simpson Strong-Tie is the leader in wood-to-wood, wood-to-concrete, and concrete-to-concrete connector design because there engineers are the best in the business.


New Home Generation, Inc. structural engineer will work directly with Simpson Strong-Tie and Benner-Nawman, Inc., 3450 Sabin Brown Road, Wickenburg, AZ 85390 - (800) 992-3833 (email: engineers and together, we will become experts in steel paneled wall-to-concrete connector/receivers, resulting in a much stronger base for our walls rather then the present industry standards of various bolts inserted into wet cement or nailing bottom track to the cement slab. Both Companies engineers are known for quality products engineered with intelligence and imagination, while Benner-Nawman, Inc. focus on


The standard drop-in anchor is an internally threaded, controlled expansion anchor.                                                                           

Built to a .03mm tolerance in expansion differential, it is designed to be used with a setting tool to ensure full anchor expansion.


This type of anchor is recessed in the concrete so if it is no longer needed simply plug or fill with cement to make the surface smooth again.


The wedge anchor is also expansion type fastener that is hammered into place then the nut is tightened for expansion.


It is the workhorse of the industry and has many different applications.  These anchors include a separate nut, lock washer, and flat washer.


The nut is tightened till lock washer is flattened for full expansion.


The nut is tightened till lock washer is flattened for full expansion.


It is designed to be hammered in and attachment to equipment is done by direct welding to the post.


Great for window, door framework and shutter installations.


The hammer drive anchor features a hardened center pin that is driven in to expand the anchor.


These anchors also include a nut and washer that can be set for various depths.


They are easy to install, because the depth of the hole is not critical and no special tool is required.


Just hammer the pin in and the anchor tensions itself automatically.


The anchor is set when the center pin is flush with the top of the bolt making it easy to inspect.


The drill anchor is a non expansion anchor that can simply be drilled into the concrete with an impact wrench or conventional hand socket.


It can be installed at a fraction of the time it would take for other types and is removable.


These fasteners do not require as much spacing between anchors as other expansion types.


The bolt type is an anchor that is hammered into place.


The external bottom bearing expansion plug expands when hammered in.


The bolt and washer are included and can be removed and used to hold material in place.


NHG Inc. proposed connectors/receivers will be tied into the footings built into the form or inserted into the cement, every two feet, 4 1/16” width, 2” sides and each are 6” long every 2’, welded together with 2” flat steel flat with the cement connected together with a strip of 3/16” by 2” flat strips welded together in lengths of 14' 9" & 14' for outside walls with flat 2" wide steel running between anchors or 29’ sections. Flat steel would be flush with concrete as well. Corner peaces are 6” in length, both directions; thereby serving as a receiver for our Homes walls allowing bottom track bolting from outside bottom track through to the inside bottom track. The two sided 2” high sides will have two pre drilled holes with ½” bolts 5 ½” long, requiring plastic trim on the inside wall on the floor/wall. Side wall connector/receivers would be 11' 9” & 11', or 23’ sections, thereby allowing an exact form for the walls, shipped in advance of the walls to our buyer’s development site, accompanied with one building and our field carpenters will educate and train our buyer’s contractor on all construction phases, to include:


Steel paneled wall-to-concrete connector/receivers

Wall assembly

Truss assembly and Hat Channel installation

Roofing installation

Interior wall installation


Hardy Board or Cement board/Drywall would be cut out where anchor sides are.


Research & Development working with Simpson’s and Benner-Nawman’s engineers will determine the best cost effective solution.


As part of Simpson’s commitment their regional training centers offer a selection of seminars for engineers, architects, dealers, contractors and inspectors. These dedicated training facilities offer opportunities for classroom instruction as well as chances for hands-on installation of Simpson Strong-Tie products. Participants can earn professional development hours (PDH) through Simpson’s registration with CSI, SEA, ICC, BIA, AIBO, ACIA and AIBD.

"The workshops are very interactive," says Charlie Roesset, National Training Manager for Simpson Strong-Tie. "Depending on the course, students may have the opportunity to view product samples, or take part in product testing and installations."


Simpson's training courses have been well-received by professionals within the building community. "There's no other manufacturer who provides such extensive training programs as Simpson," says Roesset. "Specifiers and building officials have come to rely on these courses to keep abreast of the latest code updates and technical information."


Training participants receive a certificate of completion at the end of each workshop and may earn learning units or professional development hours (PDHs). Simpson is a registered education provider with a number of industry organizations and associations including CSI, SEA, ICBO, BIA, CABO, AIBO, ACIA, and AIBD.


Fred Bentzien, S.E. with BAE Structural Engineering, has been a regular attendee at Simpson's workshops. He says the training keeps him informed of topics relevant to his industry and is a great way to keep up with his professional development hours. "Some of the courses offered by other groups are just not that interesting and they can be quite expensive. Simpson's programs are interesting, hands-on and free. It's the whole package."


Simpson’s workshops are regularly updated to reflect changes within the industry. The company has recently increased its number of high wind workshops in the Gulf Coast. With new building standards expected for that area, Simpson is working with building officials, specifiers and builders to provide hurricane and high wind design information to increase structural safety.

The company was also one of the first to offer information on corrosion and pressure-treated wood when CCA was phased out in 2004.


Simpson Strong-Tie also provides training at customer locations. In 2003, Simpson launched its training program for builders. The training classes are held at the jobsite and cover essential information on the correct installation of Simpson products. Training materials are offered in both English and Spanish. Simpson’s builder training program is a part of the NAHB Research Center’s National Housing Quality Certified Training Material Program.


These kits are the first by any manufacturer in the housing industry to conform to National Housing Quality (NHQ) Certified Training Materials Program guidelines, which seek to improve the installed performance of individual building products and ultimately improve the quality, durability, and affordability of the entire house.


The training kits include an instructional video, an instructor guide and a student guide. All of these materials are provided in both English and Spanish, and are also accessible via a CD-ROM, which is provided in the kit. The kit is intended for use by builders who actively participate in the training program. Videotapes and CDs are also available by themselves to anyone interested in learning more about installing Simpson products.


Simpson is the first building products manufacturer to become an official sponsor of the NHQ program, which is designed to foster consistency and quality in building practices.

Quality Management Development & Certification


Realizing the importance of quality assurance systems within the home building industry, the NAHB Research Center developed the National Housing Quality (NHQ) Program to help build consistency, efficiency, and continuous quality improvement in building practices. In order to satisfy customers consistently, businesses must have a planned, systematic and documented approach to quality. This is where the NAHB Research Center comes in. From consulting, to product and quality assurance system certification, to national recognition through awards programs, the NHQ Program is leading the charge in quality matters.


Because manufacturers, fabricators, and suppliers are a key component of this process, the Research Center offers a variety of quality management services to help these building partners achieve higher levels quality assurance and customer satisfaction.


NHQ Manufacturer Certified Training Materials


As a manufacturer, you know how it can go sometimes – you create an effective, practical, proven building product and introduce it to the marketplace, but it’s installed improperly on a jobsite and your company’s liability exposure skyrockets and product performance suffers.


Effective training materials are key to reducing risk and improving installed-product quality and performance. The NAHB Research Center through the NHQ Certified Training Materials Program strives to address the specific needs of manufacturing companies by providing expert consultation in the design and implementation of training materials and tools that facilitate proper installation of products in the field - across all levels from management to field installers. Utilizing a formal quality management system approach to developing and delivering training is expected of NHQ Certified Training Materials. The annual audit of the quality system and training process not only verifies compliance with program requirements but also provides evidence of due diligence in training and an outside perspective for continuous improvement.


Don’t let another day pass where ineffective training materials may cause your product to be installed wrong, and your company’s reputation and profits are in jeopardy. Find out more about the NHQ Certified Training Materials program today.


NHQ Certified Supplier Program


Building material suppliers and fabricators can benefit tremendously from a documented, customer-focused, systematic quality assurance system that establishes processes and procedures for continual improvement. Based on ISO 9000 principles, the NHQ Certified Supplier requirements are customized for suppliers and fabricators and adapted for the real world of home building.


Third-Party Quality Assurance Verification


If you’ve ever sought an ICC-ES Evaluation Report, you know that periodic, independent, third-party assessments of your company’s quality control system are usually required. As an IAS accredited organization, the NAHB Research Center is at your service for providing this type of ongoing quality assurance assessment.


NAHB Research Center can custom design our Quality Assurance Verification program to meet our company’s needs and the requirements of the evaluation service. This service includes a review of our company’s quality manual followed by an on-site audit of our quality control system. Product samples are randomly selected and returned to the Research Center’s lab for physical property testing. New Home Generation Inc. will receive a summary report of the audit and product testing.

Truss and Component Fabricators 


Paneled Steel Stud Walls


Hardboard while chosen for outside wall covering as a finished product, layers of Mesh Fabric with cement spayed between the layers is an alternate out side wall covering alternative.


All exterior walls will be strapped and anchored using a system designed using rational analysis based on wind loads calculated according to ASCE 7-98 using a Basic Wind Speed defined by ASCE 7-98 but not less than120 mph.


Paneled exterior 16 gauge 15’ L. (7’ 6” with 2” reversed track) and 12’ walls 7’ 8” L.


Paneled exterior walls will be tied together with 24’ and 30’ top track, bolted to top plates predrilled/punched, placed on top of the walls tying them together atop 4 bolts sticking up through our reversed top track attached to our paneled walls, notched out every two feet for truss location in the plant, with brackets that lay atop the four bolts before the truss is set in place, the truss bolted to the bracket to bottom/top cord of the truss, with interior/exterior inside top ceiling/outside top wall/bottom cord of truss fastened with angle iron 3/16” 30’ long, bolted to the top track (special interior/exterior 2” plastic trim for top missing sheetrock/outside wall covering with 1” overlap. Gable truss ends will have a bracket, allowing attachment of angel iron.


Corner walls will be anchored to the concrete/connector/receiver, with 7’ 9” long ¾” thick bolt that has a 6” reversed threaded nut on the end of the bolt that will screw into the bolt pre set in the connector/receiver that has it’s own nut, itself 3 3/8”” in height, the bolt inserted on the site through the wall race way, while the 7’ 9” bolt will set atop a 3/16” thick, 4 1/6” wide flat steel, the bracket itself the top track fastener for our gable prefabricated truss with it’s own race way accommodating the 7’ 9” bolt head and washer built 3/16” shorter in height then 15 accompanying trusses.




A key ingredient in the success of our Paneled Structural System are the pre-panelized load-bearing metal stud walls with SEALECTION™ 50 spray foam injected between the studs at a cost of $0.72-square-foot, much cheaper then Dow Styrofoam or Rigid Foam Board BLUECOR® Brand Insulation made of Extruded polystyrene (XPS); while SEALECTION™ 50 adheres to both exterior/interior wall covering.


The exterior walls will have SEALECTION™ 50 spray foam insulation injected off the assembly line.


SEALECTION™ 500 spray foam is an open cell semi-rigid spray-applied polyurethane foam insulation system which is made up of millions of microscopic cells that simultaneously insulates and air-seals.


It is applied as a liquid that expands over 120 times its original volume completely filling any cavity. It "SEALS" off those drafty areas like baseboards, headers, sill plates, around windows, doors, electrical outlets, pipes, etc.


It virtually eliminates uncontrolled air leakage throughout the building envelope thereby reducing energy losses.


The foam creates a continuous air barrier by adhering to other building materials (wood, plywood, foam board, etc.) and is available through DEMILEC USA LLC, 2925 Galleria Drive, Arlington, Texas 76011 (817) 640-4900.


The wall panels are pre-fabricated off-site in a panelization plant in advance and delivered to the jobsite when needed. Generally, approximately 60% of the walls in a building will be load-bearing metal stud panels, with the other 40% being non-load-bearing "stick-built" 25 gage metal studs.


Steel framing differs from wood in that most of your cuts are made ahead of time following directions from a cut list. To make a cut list, you need to count the number of members needed and list their respective lengths, always ordering 10 percent extra so that you don’t run short of materials. Manufacturers have an added savings of up to 10 percent because of lower losses from vandalism, theft and bad weather. Once you have a detailed cut list, our roll-former, after determining the price sheet can calculate the cost (cost is typically given in pounds per foot). Discounts are available with volume and with state sales tax exemption will reduce material cost considerably. This will give you an approximate cost of your material.


Securing the Roof


Roof membrane systems must comply with the most recent version of ASTM D3161, modified to reflect 110 mph fan-induced wind speeds or Miami-Dade protocol PA 107, be certified to meet minimum wind speeds of 110 mph and must be installed per manufacturers’ specifications.


Roof systems may have only one layer of covering. Hurricane straps or other hardware that connect the roof to the walls must be installed with the proper number and type of crews per manufacturers’ specifications and be designed using rational analysis based on wind loads calculated according to ASCE 7-98, using a Basic Wind Speed defined by ASCE 7-98 but not less than 120 mph.


All gable end walls will be tied back to the roof or ceiling structure with bracing designed using rational analysis based on wind loads calculated according to ASCE 7-98 using a Basic Wind Speed defined by ASCE 7-98 but not less than 120 mph.


A secondary water resistance system and under layment material will be used on the roof, applying the 16” to 18” metal roofing panels atop.


Prefabricated gable trusses will be 16 gauge steel studs with tracks and have SEALECTION™ 50 injected off the assembly line, with wall covering and have accompanying inside top track/bottom cord truss brackets. Gabel trusses will be 6” wide, allowing the interior bottom cord hat channel 29’ 4” in length on 16” centers an area for screwing.


Our trusses will be designed to our specifications and stamped by a Structural licensed Engineer.


Roof assembly will have a Class A fire-resistive rating.


In addition, 16 gauge hat channels, on 9” centers 30’ long atop the trusses and less gauge for bottom truss cord/sheet rock on 16” centers 29’ 4”, pre drilled on the sides.


Fastening hat channel on the roof trusses consist of special screws, while special fasteners will be bolted to the hat channel in the plant that the roof panel bottom fasteners marry with no screws, thereby making roof panels inner locking, that fasten the bottom 16/18” roof panel to the hat channel.


Corner walls will be anchored to the concrete connector/receivers with 7’ 9” long ¾” thick bolt that has a 3” reversed threaded nut on the end of the bolt that will screw into the bolt pre set in the connector/receiver that has it’s own nut, itself 3 3/8”” in height, the bolt inserted on the site through the wall race way. The same bolts could also be placed in wall joints if felt necessary.


In addition, sheer wall strapping, Hardboard while chosen for outside wall covering as a finished product, layers of Mesh Fabric with cement spayed between the layers is an alternate out side wall covering alternative


Testing Full-Scale Houses Subjected to Simulated Extreme Wind Loads


Building codes do not require homes to be designed or built for extreme high wind events, so having a home built “to code” means that the home may not withstand severe wind events like extreme hurricanes or tornadoes.


Safe rooms built to the FEMA/Texas Tech standards are engineered to with stand winds up to 250 mph and offer the most effective life protection technique available for high wind events.


The ultimate life/property protection plan includes a home built to the Blueprint for Safety recommendations with a tornado safe room included, but is not feasible or practical with factory assemble paneled steel stud wall homes, unless the buyer chose to incorporate a basement in the concrete package.


For more information on safe room construction, refer to Taking Shelter from the Storm:


Building a Safe Room Inside Your Home, published by the Federal Emergency Management Agency (FEMA). Contact FEMA at (888) 565-3896 or online at 


The terms ''large-scale" and "full-scale" are used in specific ways. "Large-scale" refers to structural models, or components of structures, with length-scale factors greater than, or equal to, 1:4. "Full-scale" refers to components, subsystems, or entire structures with length-scale factors of 1:1. Thus, full-scale testing is a subset of large-scale testing.


Simulated Extreme Wind experiments on our Home would require sustained wind speeds of 150 to 200 mph (~ 65 to 90 m/s), with a reasonable representation of atmospheric turbulence, over an area large enough to engulf a residential, single-family dwelling or other structure of similar size. The flow structure and size of the facility's wind stream would have to be sufficient to create a realistic flow around the structure and thereby generate appropriate and representative spatial and temporal variations of wind-induced pressures. At the present time, there are significant gaps in the meteorological data for severe wind events.


The Federal Emergency Management Agency (FEMA) and the insurance industry have both determined that significant improvements in the wind resistance of buildings will only be achieved when there is a demand for wind-resistant or hazard-resistant construction at the local and individual level (Cermak, 1998; FEMA, 1992).


As a result, both FEMA and the insurance industry have embarked on pilot demonstration projects to highlight the benefits of hazard-resistant construction and other wind-hazard mitigation measures.


The research, engineering, and scientific communities have provided some of the technical underpinnings for reducing the vulnerability of buildings and other structures to wind damage. Significant work remains to be done in this area to ensure that key vulnerabilities of a particular structure are identified and that technically sound, cost-effective solutions are developed and implemented. Unfortunately, reducing vulnerability to wind-hazards is not just a question of developing appropriate technical solutions. First, wind-hazards are created by a variety of random events with large uncertainties in the magnitudes and characteristics of the winds. Substantial differences in wind speeds and characteristics can be caused by changes in elevation and by averaging time associated with a particular observation, as well as the topography and roughness of the upwind terrain.


No data are available on wind loads on buildings in the eye wall of a hurricane or in a tornado. No data on buildings subjected to thunderstorms and tropical storms have been reported in the literature.


Experience with wind-tunnel model studies has shown that the gust structure of the wind plays an important role in the development of wind loads on structures. However, most of the existing field data on wind loads are limited to simple building shapes in open exposures subjected to winds generated by the passage of frontal systems rather than severe windstorms. The lack of knowledge about wind loading and structural response in severe windstorms is a significant impediment to establishing meaningful standards for structural systems and for improving structural performance.


Given the current state of knowledge, a number of assumptions and considerable engineering judgments are necessary in the design of low-rise structures. In most cases, these assumptions and judgments lead to conservative designs. Thus, reducing the uncertainties could lead to economical designs more consistent with the actual level of risk.


Current test methods apply loads uniformly over the surface of the specimen and have not included combined in-plane and out-of-plane loading.


Numerous remedial measures have the potential for improving the wind resistance of a building, and it is a relatively straight forward matter to test these measures at the component level. It is far more difficult, however, to assess the effectiveness of these measures in a full-scale system where their attributes interact synergistically.


Building components of a steel constructed homes value to the behavior of the full-scale building system can be determined only by testing a full-scale, complete system.


Significant advancements could be made in construction practices if the properties of a total building system could be evaluated in a full-scale turbulent wind flow representative of a hurricane, thunderstorm, or other extreme wind event.


The most economical solution would be to deploy instrumented manufactured homes in the paths of hurricanes, surrounded by sufficient instrumentation to quantify the winds in the storm.


A number of experiments might also be conducted, depending on costs and the availability of the facility. New Home Generation will explore ways in which to determine the following:


Validation of systemic retrofitting techniques.


Fatigue of elements and connections in a full-scale system.


Determine damage fragility curves.


Determine Damage sensitivity to wind speed characterization (peak gust, sustained wind).


The performance of the building envelope, new construction techniques, and retrofitting technology.


Performance of the building envelope.


Internal pressure distributions on internal walls and ceilings.


Determining the wind speed at which the building envelope is compromised in a full-scale building - With current design criteria and construction practices, roof and wall systems may be more vulnerable to failure or water damage than protected windows and doors.


Validation of construction techniques, practices, materials, and building code provisions.


Testing of sheathing systems by applying realistic spatial loads and temporal variations of wind loads, improving load/resistance characteristics if necessary.


Testing of variations in internal pressures in a building with multiple rooms, creating strong room evaluations for residential structures.


Testing of the performance of the building envelope with emphasis on system performance relative to Window and roof system behavior relative to building envelope performance - A breach of the building envelope, such as the failure of a window, can lead to pressurization of the building. Little is known about how pressurization is propagated throughout a building.


Validating construction techniques, practices, materials, and building code provisions in the context of overall building performance - The benefits of a particular retrofitting measure or set of retrofitting measures could be ascertained, as well as whether the buildings will simply fail in another mode at a slightly higher wind speed, rather than waiting for a storm to provide validation, it would be possible to create representative wind loading conditions in a controlled environment.


Testing of the behavior and performance of rooftop appurtenances - Failure of mechanical system components and other rooftop appurtenances have caused significant damage to the interiors and contents of buildings


Testing of the performance of porch roofs and roof overhangs - Roof failures frequently originate at porches and roof overhang areas.


Validation of full-scale computational resistance models - Intense loading generally produces nonlinear structural behavior in certain components, connections, and at the system level. More realistic load modeling would result in more realistic modeling of the behavior of structural systems.


Realistic simulation of complex loading patterns and the response of the structural system to these loads - Idealized loads specified in building code provisions and simplified analytic procedures sometimes lead to design requirements that are inconsistent with the observed performance of buildings in severe windstorms.


Development of improved component tests - Many of the current tests for structural components and connections do not adequately reflect the actual physical processes at work in a severe windstorm.


A variety of tools for research and development are available for determining the characteristics of wind-resistant structures, including analysis, numerical computation, wind-tunnel testing of small-scale models, wind-tunnel testing of large-scale or full-scale components, full-scale testing in the natural environment, and large-scale or full-scale testing of components and structures in simulated wind conditions under forces generated by actuators.


These tools have contributed to a growing understanding of how a wide range of structures, including tall buildings, low-rise commercial, industrial, and institutional buildings, residential buildings, and suspended-span bridges perform in high winds. Their potential for improving the economy and performance of structures of all types remains high. However, this knowledge alone has not been sufficient for the widespread implementation of improved designs and construction methods.


The manufacturing sector needs to be involved in implementing research results because it supplies the large variety of materials and components that make up a constructed building.


Engineers and contractors can only implement improvements if they have information on the performance of new products and materials. Because of the small market and difficulty of carrying out qualification tests on a limited budget, this information is not often developed.


Therefore, New Home Generation, INC. will design a testing and certification mechanism qualifying proposed new items or concepts for improving the wind resistance of our proposed home structures.


To date, the experimental focus in wind engineering has been in the use of wind tunnels, mostly boundary-layer wind tunnels (Cermak, 1995). Wind-tunnel facilities have provided a wealth of data and understanding about the nature of wind loads on a wide range of structures, but wind tunnels can only test models and cannot test causes of failure of structural elements. Although more needs to be done in this area, calibrations with (albeit limited) full-scale data suggest that the results are consistent with expected loads and pressures on real structures (Cermak, 1995).


The results of wind-tunnel investigations, and supporting analytical and numerical computations, have led to significant improvements in building codes in the past two decades (Cermak, 1995).


Related investigations have focused on evaluating the response of structural and nonstructural components (e.g., shear walls, roofing systems) to wind-induced loads, with testing performed frequently at large-scale, or even full-scale. Commercial testing—often proprietary—is also quite common. A number of complementary full-scale field investigations involving the use of natural environmental winds have also been performed.


The design of engineered structures has effectively incorporated aerodynamic characterizations obtained from wind-tunnel experiments, in some cases complemented by full-scale observations from the natural environment.


Structures designed to resist actual fluctuating wind loads would perform more predictably than structures designed according to current wind-load criteria and could possibly be less costly to build. The savings could be used to upgrade components of the building to further improve its overall performance. Analyses to failure of wood-frame homes, manufactured housing, and low-rise commercial structures, in conjunction with component testing, could help to determine their behavior leading to failure and improve their design.


Presently, science offers the means to validate computational results based on component and other tests for our steel homes from full-scale measurements (generally nondestructive) or, in a statistical sense, from detailed analyses of post-disaster damages.


The problems include the development of acceptably scaled turbulence and a significant concern that destructive testing would produce debris that could damage the wind tunnel or fans.


Additional study would be required to determine if our Homes could be used for large-scale structural research.


World's Largest Portable Hurricane Wind and Rain Simulator


New Homes Generation, INC. will explore every avenue to wind test our Homes, working many experts to include the University of Florida, Dr. F. Michael Bartlett, P. Eng., Associate Professor, Department of Civil & Environmental Engineering and Professor Greg Kopp of the University of Western Ontario, London, Canada utilizing there computer-controlled simulator creating a tempest of our home.


On February 28, 2003, Dr. Michael Bartlett, an Associate Professor in the Department of Civil & Environmental Engineering at the University of Western Ontario, gave a lecture titled “Testing Full-Scale Houses Subjected to Simulated Extreme Wind Loads.”

Dr. Bartlett began his presentation with some examples of residential wood-framed structures destroyed by extreme wind events. A phenomenon known as “down burst” generates high velocity winds to which residential wood-framed construction is vulnerable. Dr. Bartlett discussed the complex response of wood-frame roof, wall, and floor systems and the effect of connections on the interaction of these systems. Full-scale testing provided an effective means to investigate how load paths develop and are maintained up to failure. A full-scale test of a corrugated fiberboard shelter approximately 16 by 20 ft in plan subjected to simulated hurricane-force wind loads was conducted. The fiberboard shelter performed well but failed prematurely where the tension was applied through the thickness of the corrugated fiberboard and where the quality of construction was imperfect. Dr. Bartlett demonstrated that finite-element analysis conducted in conjunction with the full-scale experimental test identified regions of high stress concentration. This type of analysis could be effectively used to identify possible failure points of the structural system but could not predict failure due to construction quality. Dr. Bartlett discussed the design and effectiveness of the testing apparatus and the instrumentation used in the full-scale test and briefly described some preliminary plans for a more effective test facility. The seminar concluded with a question and answer session, which segued into an informal discussion regarding the complexities of full-scale testing and alternative testing configurations. Submitted by Gordon Warn, UB-EERI secretary


Two days before the June 1 start of the 2007 hurricane season, University of Florida wind engineers unveiled the world's largest portable hurricane wind and rain simulator. 


Mounted on a trailer, the industrial-sized behemoth is composed of eight 5-foot-tall industrial fans powered by four marine diesel engines that together produce 2,800 horsepower. To cool the engines, the system taps water from a 5,000-gallon tank aboard a truck that doubles as the simulator's tow vehicle.


UF civil and coastal engineers plan to use the simulator to blast vacant homes with winds of up to 130 mph - Category 3 on the Saffir-Simpson Hurricane Scale - and high-pressure water jets that mimic wind-driven torrential rain.


The goal: to learn more about exactly how hurricanes damage homes, and how to modify them to best prevent that damage.


"We want to conduct experiments to evaluate real homes in communities that are impacted by hurricanes," said Forrest Masters, an assistant professor of civil and coastal engineering and the leader of the project. "This simulator also gives us the ability to test home retrofits and new building products aimed at preventing hurricane damage."


The simulator, which cost about $500,000 in parts and labor, was designed and constructed entirely by Masters, lab manager Jimmy Jesteadt and a team of undergraduate students.


It is one of a kind.


Unlike previous, smaller simulators, the new simulator uses an innovative hydraulic system, rather than chains or mechanical drive trains, to transfer power from the engines to the fans. Designed by Linde Hydraulics Corporation and Cunningham Fluid Power Inc., the engines spin pumps, which then drive fluid through motors housed in the fans. The result is lighter, less bulky and safer than traditional drive systems, Masters said.


At full power, the fans turn at about 1,800 revolutions per minute, producing wind speeds of about 100 mph. A custom-built duct reduces the space available for the air to flow through; ratcheting up the wind speeds to a potential 130 mph. Steering vanes allow the engineers to direct the air wherever they want it to blow.


Implanted in the vanes, the water jets can simulate the most extreme rainfall of up to 35 inches per hour, although 8 inches per hour is more typical, Masters said.


The simulator is the latest addition to a growing arsenal of hurricane research equipment designed and assembled by UF wind engineering researchers trying to learn more about ground-level hurricane winds and how they affect structures. In a related project, the researchers built several portable hurricane wind monitoring towers that were deployed in the path of land-falling hurricanes in recent years.


"When this program first started, we brought the lab to the hurricane," Masters said. "Now, we're bringing the hurricane back to the lab."


Rick Dixon, executive director of the Florida Building Commission, said state officials began to tap UF research for help in strengthening the state's hurricane-related building codes shortly after Hurricane Andrew in 1992.


The 2004 storms showed that while improved codes were effective in preventing catastrophic building failures, challenges remained in blocking wind and water intrusion, he said. It will take more research to learn how to protect windows, doors, soffits, roof coverings and other so-called "components and claddings" – research for which the new wind simulator will be pivotal, he said.


"The test facility that Forrest has built allows us to evaluate those components and claddings and determine where they are failing," he said. "So if the building code establishes minimum performances, than that can give us new standards for upgrading the building code."


University of Florida pursued a grant from the Institute for Business and Home Safety, an insurance industry research association, to partially fund a $15 million center that Gainesville officials say could provide an economic boost to the area.

The facility will allow entire buildings to be tested against hurricane-force wind and rain to gauge what materials and techniques can best withstand a disaster, said Tim Reinhold, director of engineering and vice president of the institute. Reinhold compared the center to the crash-test facilities for vehicles run by the National Highway Transportation Safety Administration.

"There are issues that we're not going to answer with the kind of test methods that are out there right now," Reinhold said.

The center, referred to as the "Wind Hazard Research Facility," will be able to subject a two-story building to between 130 mph and 140 mph winds, equivalent to a Category 4 hurricane, Reinhold said. A one-story building in the center could be subjected to winds between 170 mph and 180 mph, which would exceed some of the strongest winds recorded by the National Hurricane Center during Hurricane Andrew in 1992.

Researchers at UF's Department of Civil and Coastal Engineering are taking the lead on the grant and have selected a site owned by the city of Gainesville at the Airport Industrial Park as their first choice for such a testing center, said Linda Dixon, assistant director of UF's Facilities, Planning and Construction division.

"This would be a one-of-a-kind facility," Dixon said. "It would be an incredible benefit in terms of the research we could do here if we were successful in getting this grant."

Gainesville city commissioners
February 26. 2007 was asked to sign off on plans to use the industrial park property for the project and to provide a letter of support for the grant application.

The Institute for Business and Home Safety is also expecting grant applications from Florida International University and the University of South Florida, Reinhold said. In early April, the institute will decide whether to go ahead with the grant and choose a university to house the facility, he said.

The center itself would have a footprint of about 53,000 square feet, bigger than a large supermarket, Dixon said. It would sit on about 10 acres of land and include large, semi-circular "baffles" designed to reduce the noise and the intake and output from the wind generators.

Gainesville Economic Development Director Erik Bredfeldt said the facility is designed to have a minimal impact on neighboring buildings and noted that it will be quiet enough to adhere to city codes.

Hurricane testing now largely consists of either placing construction materials in a wind tunnel or else bringing rigs of turbines or engines to already-built homes, Reinhold said. But these methods face limitations such as an inability to see how a full building reacts to hurricane pressures and a lack of ability to simulate water damage, he said.

The facility is the only one in the world designed to subject full-sized buildings to hurricane conditions in controlled circumstances, which could yield more information than existing tests, Reinhold said.

"You've got to build a structure and chase everything through it to really understand what's going on," Reinhold said.

If UF is chosen for the grant and the facility is built at the Airport Industrial Park, Gainesville officials believe the project could provide a jolt to economic development efforts in east Gainesville.

The facility itself will employee between 20 and 30 people full time and the construction of the buildings to be tested would require the hiring of additional contract labor, Dixon said.

In addition, Bredfeldt said the city could see interest from insurance and construction material companies who might want to locate near a unique facility that could have important implications for their industries.

"It probably puts you on a map for a universe of people you don't think about every day," Bredfeldt said.

The National Aeronautics and Space Administration’s (NASA’s) establishment and use of wind tunnel and propulsion test facilities have helped the United States build and maintain aerospace competitive advantage across the military, commercial, and space sectors. Are these major facilities continuing to serve the current and future needs of the nation at large? At the request of Congress and NASA, the RAND Corporation performed a yearlong study of the 31 such facilities at three NASA centers. The study examined current and future national needs for wind tunnel and propulsion test facilities, the technical competitiveness of NASA’s facilities, functional overlap and redundancy among NASA facilities, and management issues. The study recommends that NASA develop an aeronautics test technology vision and plan; analyze the viability of a national test facility plan with the Department of Defense; continue to use an appropriate mix of facility, computational, and flight testing; maintain an identified minimum set of NASA facilities, specifically leaving out two facilities that are not serving national needs and are weakly competitive, redundant, and poorly utilized; identify financial shared support to keep its underutilized but important facilities from entering financial collapse; and pursue selected investments in test facilities. A companion report (Wind Tunnel and Propulsion Test Facilities: Supporting Analyses to an Assessment of NASA’s Capabilities to Serve National Needs, TR-134-NASA/OSD) presents additional details of the researchers’ findings.
