“re-thinking construction….with a new way to build”

__________________________________________________________________

Omega Manufacturing Limited (OML) and Omega Building Systems Limited (OBSL) are two

very unique businesses located in Trinidad and Tobago, West Indies. Formerly known as Agosti-

ni Industries Limited, the Omega brand was established in July 2010. Since then, it has devel-

oped into two individual entities within the manufacturing and construction industries of the

country.

OML manufactures Omega boards, structural insulated panels (SIP), structural supports for SIP

system, cold formed steel (CFS) roof trusses, floor joists, aluminium windows and door frames.

OBSL designs and constructs homes and buildings using several of the building products and

systems produced by OML. These two companies, while independent, work symbiotically with

one another allowing for efficient flexibility in their business model—particularly regarding the

needs of clients. Some customers may require specific products while others may require prod-

ucts in addition to a design that incorporates the various building systems into a finished product.

Over the past 15 years, Agostini’s and Omega Building Systems, have collectively built and

completed numerous projects in Trinidad and Tobago as well as the Caribbean. Also in French

Guiana, where the products and various building systems have been tested and approved, they

have been used in many already existing developments.

All projects undertaken to date have been of a Design & Build arrangement and OBSL is

equipped with a full design and construction team, comprising of consultants and direct staff.

6.0 Omega Manufacturing Limited’s Products & Its Construction

Omega Board

Omega board is a technologically-advanced building material that has revolutionized current building

practices. Its main component is Magnesium Oxide, an element that has been around for quite some

time, used mainly by the Chinese. There are many different ways and combinations in which these

boards are produced. However, the one commonality they share is their superior performance in just

about every category when compared to traditional wood, gypsum, and cement-based products. De-

pending on the intended use of the board, ingredients as well as sizes vary in order to facilitate the

different applications of the product. Extremely strong Omega boards may be quite heavy and used

for SIP’s or partition walls, while others may

be quite light such as boards used in a ceiling

tile.

Omega Board is light weight, tough, and vir-

tually impervious to fire, as they are non-

combustible boards. On the other end of the

spectrum, these boards are unaffected by wa-

ter, mould, mildew, and insects, for example

termites. They are environmentally friendly

as most of the ingredients used in producing

the board are naturally occurring elements—

making them non-toxic as well as asbestos

free.

This Class A building material is extremely

durable and maintains its dimensional stabil-

ity even when wet. It addition, Omega boards

have an exceptional bonding surface making

them quite versatile, depending on the clients

desired use. Omega board can be used in

many different areas as its ingredients are

altered to fit its desired purpose. Some of

these different applications include structural

insulated panels (SIP), dry walls, ceilings and

ceiling tiles, cupboard doors, partition walls,

and much more.

Omega uses only the highest quality ingredi-

ents when producing Omega board to ensure

the final product is one of the best in its class.

Structurally Insulated Panels

Structural Insulated Panels (SIP Panels) are

high-performance building panels used for

floors, walls, and roofs. Using Omega

boards, Omega produces their own in-house

custom SIP panels. Two sheets of board are

placed into a mould and a high-density poly-

urethane foam is injected between the two

boards. The mould is then left to cure as the

chemical reaction bonds the materials togeth-

er and we are left with a sandwiched panel.

There are many benefits and advantages to using SIP’s rather than the traditional means of bricks and concrete. Being a fairly new product to this region, people are often hesi-tant to use it but are always eager to learn more about it—even though it’s been around for quite some time. Use of our building sys-tem appears identical to the naked eye when compared to that of a traditionally built structure. The main differences between the two comes when comparing its cost, strength and quality. This type of building system is great for residential, agricul-tural, and commercial applications but can also be used in almost all building types, ensuring a higher quality structure and faster construction time.

Cost Saving

Advantages Of Using Omega SIP’s

The use of SIP panels can save you in the long and short run. All panels are pre-engineered for their desired use before being sent to their final destination. Whether it be for plumbing, electrical, win-dows, or doorways, the panels are finished and ready for a quick installation upon arrival. Its light weight also allows for quick assembly and easy handling. Construction time can be further reduced, as Omega’s panel system requires smaller work crews than it takes to prepare a concrete wall. With this increased productivity, there is a substantial reduction of overhead costs. The sheer speed for ex-ample in which these panels can be installed rapidly reduces labour cost and preliminaries.

Concrete Masonry Unit walls increase in weight as mass increases. The weight of SIP walls increase very little as thickness/mass increases, as PU is the only material that increases in width/mass. The average weight increase for 1220mm X 2745mm panel, is 3.2kg per 50mm increment. Reducing the overall weight of a structure which allows for a significant decrease in foundation material, and de-creases the elevated weight, allowing superior performance in seismic loading, which again signifi-cantly decreases cost. Concrete walls also need time to cure, which can slow a job down dramatically depending on the scale of the operation. Also, if a mistake is made, it takes a great deal of time and effort to rectify concrete that has already set and been put in place.

In addition, Polyurethane foam serves as a great insulation, with an R value of over 20 naturally, this leads to a reduction in electricity costs when trying to keep the building cool or in some cases warm. The end result being an energy efficient building that is rectified in a reasonable period of time.

Strength

Quality

SIP panels are excellent for building, as testing shows SIPs are structurally sounder than conventional construction. They are designed to withstand nature’s various elements, and have already sur-vived real world natural disasters for years. They are strong and not as rigid as traditional concrete when it comes to events such as earthquakes. A compo-site panel has a vertical load bearing capacity in excess of 25kN/m and a racking load resistance in excess of 1kN/m. Different sized panels are used depending on its intended purpose, whether it be for interior or exterior use.

Structurally, a SIP can be compared to an I-beam: the foam core acts as the web, while the facings are analogous to the I-beams flanges. All of the elements of a SIP are stressed; the skins are in tension and compression, while the core resists shear and buckling. Under load, the facings of a SIP act as slender columns, and the core stabi-lizes the facings and resists forces trying to deflect the columns. The thicker the core, the better the panel resists buckling, so larger-core SIPs offer more insulation and are stronger as well. A typical SIP wall panel will withstand vertical compression of over 900kg/m before structural damage occurs. No conventionally framed wall could survive this much weight. These panels are load bearing, and if used with our roofing system, some structural walls can be removed, or replaced by partition panels. By cutting down on the amount of structural reinforcements needed to support the building, costs are again reduced and less materials are required.

Omega Panels are all produced in house and quality is monitored very closely. This is done to ensure

that our product lasts for years and fully meets the requirements of our customers. All panels start as a

basic 4x9 unit, but are then customized and tailored to fit the requirements of the job. Since there is

no on site production, as is done with brick and concrete, we can ensure quality without being pre-

sent. Erecting the panels is a fairly simple process, and once this is done properly the panels are

strong, durable, and very low maintenance. Working with Omegas SIP system is always very cleanly

and neat, while working with concrete can get quite messy. This makes it easier to visually pick up on

any minute flaws during erection, and again ensure a top quality installation for consumers.

The image above shows how SIP’s are interconnected and secured to the floor, in a domestic setting. A steel tie rod Is placed be-tween every few panels , and bolted at either end.

Combustibility

Green Construction

The issue of how a material performs in the presence of fire is a primary concern to the code authori-ties. Fire has three requirements: fuel, ignition, and oxygen. SIPs have no "air" within their solid cores of insulation. The fire cannot "run up the wall" cavity. In Canada, the National Research Coun-cil has determined health risks associated with various combustible materials by essentially summing all of the risks of a material into a single index of toxicity. The higher the score, the more dangerous the material. Most building codes prohibit any material more toxic than wood smoke. But even wood smoke can kill you if you inhale enough of it, but any score below 50 at least gives you a chance to escape. Any material scoring above 100 should probably not be in your house.

Magnesium Oxide board, which is used in our SIP panel, conforms to the following: United States & Canada US ASTM E136 - non-combustible British Standard 476: Part 4: 1970 - non-combustible United States and Canada Surface Burning Characteristics CAN/ULC-S102 and US ASTM E 84 (Flame Spread Classification "FSC" = 0 / Smoke Developed "SD" = 0) Flame Spread and Smoke Development Rating is Class 1 or Class A British Standard 476: Part 7: 1997, Class 1 for Sur-face Spread of Flame A typical Magnesium Oxide SIP Wall section has a minimum fire rating of 60 minutes without the need to apply additional sheathing.

In today’s modern day society most companies try their best to be socially responsible, in one way or

another. These panels are a very “green” product. Its main ingredient is Magnesium Oxide, which is a nat-urally occurring element. It is all around us in many

things that already exist in nature, and therefore is not toxic nor harmful to humans. Production of Ome-ga panels is also a very clean process, no CFCS’s are

produced and minimal energy is required. After a panel has been fabricated to its intended use, there is often scrape. This scrape is then recycled into dust

and reused as raw material for future panels. This creates less jobsite waste along with a reduction in theft of materials.

This Clermont, Georgia SIP house sur-vived a 1998 tornado with superficial dam-age while 27 conventional houses around it were destroyed. Resistance to horizontal loads is called shear resistance — the ability of an object to withstand horizontal forces without damage. Racking resistance is the ability to stand this force without deforming.

The concrete foundation of this Sumner County, Tennessee SIP house crumbled and the porch was swept away, but the SIP walls and roof are still there. The contents of the house were only slightly damaged. Using the standard ICBO and BOCA ap-proved test (ASTM E-72-80, “Conducting Strength Tests of Panels for Building Con-struction, Section 14), testers found that a standard 4'x8'x4-1/2" SIP panel wall had over three times as much resistance shear stress as a traditional wall assembly. At a load level that would destroy a con-ventional wall a SIP wall will deflect about 1/8".

Repeated engineering tests show that SIP construction is stronger than conventional wall and roof framing. A typical SIP wall panel will withstand vertical compression of over 2000 lbs. per linear foot before structural damage occurs. No convention-ally framed wall could survive this much weight.

6.3 What Is Cold Formed Steel?

Cold Rolled Formed Galvanized Steel Building System

Cold Formed Steel is a method of

forming steel without the use of

heat. (Unlike the conventional hot–

rolled steel used in universal beams

and columns). CFS members are

made from structural quality galva-

nized sheet steel, and are formed

into shape mainly by roll forming.

Roll forming is a process where

steel is pushed through a series of

rolls until the desired shape is

achieved.

The proposed Cold Rolled Formed Galvanised Steel Building System can be adapted for any region from tropical to temperate countries and can withstand both earthquakes and hurricanes. The concept introduces light elements that can be manipulated and erected by one, two or three people without the use of heavy machinery. The materials used for structural components have eliminated the use of wood products which allows the house to be termite proof and resistant to mould and moisture if well ventilated. The structure is composed of galvanised cold-formed steel for the walls and roof trusses. All profiles are manufactured in Trinidad and Tobago by roll forming 1.2mm G90 galvanised steel and assembling with galvanised bolts and self-tapping screws. The main profiles used are;

Omega profiles usage:

Stud for external wall

Top and bottom of trusses

Purling U profiles usage:

Top and bottom of wall panels

Top and bottom of large openings for windows and doors.

Eave purling

Ridging

Ventilation bash-board

Bash board Small C profiles

Vertical and oblique beams inside trusses

Cold Formed Galvanized Steel Roof Trusses

Advantages of CFS Roof Trusses

As mentioned earlier, cold formed galvanized steel is one of Omegas main building components. It is

manufactured into many different profiles. Each serves a different purpose as it comes together, to

form one unified and rigid structure. Applying CFS systems to roofs has many advantages over tradi-

tional wood, and I-Beam structures. If used with Omegas SIP system, many structural walls can be

removed, had there been an original plan to use concrete walls. This can be done because the Galva-

nized trusses can reach spans of up to 9.2m, along with the load bearing abilities of the SIP system.

Concise Quality- Light gauge/ cold formed steel enjoy uniform manufacturing tolerances. Cold-formed steel is always dimensionally correct and does not contain the knots, twists, or warps commonly found in wooden framing materials.

Ease of Installation- Cold-formed steel framing in-stalled quickly. The components of a lightweight, steel-framed assembly, including studs, track, joists, etc., can be assembled quickly and easily into prefabricate panels or assemblies. Cutting these steel components ahead of time and to the precise dimensions you require, can save you time and help produce less waste

Light Weight- Job sites with steel framing require less

man power due to 30-50% less weight compared to tra-

ditional wood counterparts. Smaller crews mean smaller

cost.

Durability- Galvanized steel can resist almost any con-

ditions, and is not flammable. It has already been imple-

mented in many buildings around the world, some of

which have been tested heavily by nature.

Building Accuracy- Cold formed steel allows for more

accuracy and evenness during the build. Using CFS it

maximizes your crew’s ability to get the job right the

first time, as reworking costs time, money, and in some

cases profit.

Low Maintenance- Galvanized steel has virtually no maintenance, and termites as well as mould

have no effect

Greater strength- Light gauge/ cold-formed steel components with same outside dimensions as

their wooden counterparts are lower in bulk and provide greater strength for many applications. The inherent strength of steel also usually translates into a need for fewer members and in many cases smaller members. For example steel strength for tension is about twenty times stronger than the A

variety of products thickness, size and arrangement of light gauge/ cold-formed steel members ena-ble engineers to meet big verity of owner demand for bigger and larger open space.

Cold Formed Galvanized Steel Floor Joists & Decking

Omega Manufacturing also

produces their own alterna-

tive flooring system, which

fits hand in hand in the way

their buildings are designed.

It is comprised of cold

formed galvanized trusses,

floor joists, and Omega

Board. There are two types

of floors, one for domestic

use, and one for commer-

cial use. Both have a maxi-

mum span of 4.75m.

The domestic floor uses

galvanized trusses and

joists below. On the surface

sheets of 38mm Omega

Board are put in place, as

each sheet is pre-engineered

to interlock into the other.

The Commercial floor uses galvanized trusses and joists below as well. On the surface however, it uses steel decking along with two layers of Omega board. This is done to increase strength and stability, along with muffling the sound of footsteps above.
