Introduction
Timms Construction Company specializes in technologically advanced methods of Timber Frame construction suitable to the modern age by working with the largest companies overseas such as , BK Structures UK, Canadian Timber Frames Canada, Amwell Corp of USA ,Suteki of Japan, Weihag of Germany & Boise Cascade from the United States who are some of the foremost their field.
Timber structures are used the world over because it has a better strength to weight ratio as compared to steel & concrete and can also outlive them both due to its quality & durability. Along with high durability, timber framed structures when designed well can create stunning features externally as well as provide beauty, warmth & functionality in the interior of the structure thus giving it an unmatched aesthetic appeal.
Timber frame construction is undeniably the fastest form of construction. It’s typically 40-50% faster than steel & 90-100% faster than concrete. Due to the nature of construction & advanced technologies applied execution of activities take place simultaneously on site. This technology greatly improves precision that accelerates the build-time on sites.
Unlike some building materials, wood construction can proceed in any season and almost any climate. Wood is lightweight & can be fabricated within minutes on site so when its time to renovate, it's hard to beat wood: whether you want to move a wall or extend a room, it's much easier, faster & more stable with wood.
A 5000 sq.ft. Villa will take 4 weeks to construct on site.
A 10,000 Sq.ft. club house will take 9-10 weeks to construct on site

Standard Specifications
Wall Systems Builders can choose from a variety of wall sheathing products that range in cost, strength, insulation value, and ease of installation. Of the options available, plywood and oriented strand board (OSB) are the strongest and most durable. These wood structural panels add shear and racking strength – important characteristics that are engineered to help a structure withstand the forces of high winds and earthquakes. Wood-sheathed walls are also easy to build and easy to insulate for high R values.

Lateral Design
Wood-framed buildings can be designed to withstand lateral loads such as those caused by high winds or seismic forces. The elements that enable a building to withstand such forces are its shear walls and diaphragms. Framing, wood structural panel sheathing, and connections are all important components in these construction systems.
Shear Walls & Diaphragms
A diaphragm is a flat structural unit acting like a deep, thin beam. The term “diaphragm” is usually applied to roofs and floors. A shear wall, however, is a vertical, cantilevered diaphragm. These construction systems can be used when designing a building for lateral loads, such as those generated by wind or earthquakes.
Floor systems
Joists Joists are Consistent, High- Quality Floor Framing System. Joists are the ideal choice for designers and builders who want to provide their customers with high-quality floor systems. They provide consistent performance for the most demanding residential applications. They are simple to install, allow greater design flexibility because they can span long distances, are dimensionally stable, and are lightweight and easy to handle.
Floor Beams
Floor beams have superior strength and stiffness and are available in a range of grades and sizes. Framing-grade glulam beams can be used in a wide range of concealed floor framing applications. When the beams are exposed, such as second story floor framing where the floor beam is exposed to the floor below, an architectural-grade beam combines strength with the warmth and beauty of wood.
Roofing Systems
Trusses
A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof.Trussesusually occur at regular intervals, linked by longitudinal timbers such aspurlins. The space between each truss is known as abay.
Roof Trusses are fabricated on site
Joists for Flat roofs
When the beams are exposed, such as second story floor framing where the floor beam is exposed to the floor below, an architectural-grade beam combines strength with the warmth and beauty of wood.
Water proofing
A primer is applied to the roof
Primers aid in the adhesion of the coating by providing a bond between the surface of a roof and the roof coating. Primers come in many different forms, the type of primer employed will be based upon the substrate, weather conditions, and the type of coating being applied.
Self-Adhesive double viscousMembrane
Modified self-adhesive Bitumen Roofing Membranes by modified asphalts with non-woven polyester or glass fiber reinforcements produces waterproofing systems that exhibit tremendous strength, elasticity and weather ability. The core of the membrane is viscous.This eliminates much of the leakage concerns associated with roofing systems.
Asphalt shingles
Asphalt shingles are then installed over the Self-adhesive Bitumen membrane. Asphalt shingles used by Timms Holdings has a lifespan of 35 years

Engineered Wood products for Superior Performance
Engineered wood products are used in timber frame construction they are a high-performance, consistent, reliable and environmentally responsible choice for construction.
Glued Laminated Timber
An engineered stress-rated product created by bonding together individual pieces of lumber. Can be shaped into forms ranging from straight beams to complex curved members. Used for headers, floor girders, ridge beams and purlins, arches, domes, exposed applications including bridges and utility structures, and much more
I-joists
I-joists are "I"-shaped structural members comprised of top and bottom flanges that resist common bending stresses bordering a web that provides outstanding shear performance. Used extensively in residential and light commercial construction for both floor and roof framing.
Oriented Strand Board
Structural wood panels manufactured from rectangular-shaped strands of wood that are oriented length- wise, arranged in perpendicular layers, laid up into mats, and bonded together. Commonly used for sheathing, I-joist web material, upholstered furniture, and many other construction and industrial applications.
Rim Board
Works in concert with wood I-joists to deliver a complete framing solution. Rim boards fill the space between the sill plate and the bottom wall plate, or between the top and bottom plate in multi-floor construction, and are an integral structural component that transfers both lateral and vertical forces.
Structural Composite Timber
Created by bonding layers of dried and graded wood veneers, strands or flakes with waterproof adhesive into blocks. Solid, highly predictable and uniform, SCL products are sawn to consistent sizes and are virtually free from warping and splitting. Commonly used in headers, beams, rafters, studs, joists, columns and I-joist flange material.
Environmental Impact
Nontoxic raw Materials
The raw materials are primarily made with fast-growing, renewable lumber, harvested from sustainably managed North American forests, and manufactured with virtually no waste. They are certified to the environmental and sustainability requirements of SFI (Sustainable Forestry Initiative) and CSA (Canadian Standards Association), and can qualify for LEED credits.
Trees produce oxygen and absorb carbon dioxide, helping to reduce global warming.
Timber is a totally renewable resource; European softwood forests are growing by over 250 million m3 every year.
Renewability Completes Natural Cycle
Wood is the only naturally renewable building material, and that cycle of growth has an added benefit. When a young forest is growing, it produces 1.07 tons of oxygen and absorbs 1.47 tons of carbon dioxide for every ton of wood. But as the forest matures, growth slows, and the absorption rate drops off. Harvesting a mature forest sequesters the carbon in the wood, meaning it will not be released into the atmosphere. A 2,400-square-foot wood-frame house, for example, has 28.5 tons of carbon dioxide sequestered, roughly equivalent to seven years' worth of emissions from a small, light-duty car. Harvesting mature forests also allows new, young forests with a rapid rate of carbon absorption to take their places, continuing the naturally perfected cycle.
Wood Offers More Product for Less Energy
Simply put, manufacturing wood is energy efficient. Compare the amount of energy it takes to produce one ton of cement, glass, steel, or aluminum to one ton of wood:
5 times more energy for one ton of cement
14 times more energy for one ton of glass
24 times more energy for one ton of steel
126 times more energy for one ton of aluminum
Wood products make up 47% of all industrial raw materials manufactured in the United States, yet consume only 4% of the total energy needed to manufacture all industrial raw materials. Wood's manufacturing process alone makes it the environmentally friendly choice in building materials.
From the extremely detailed charts given below we are able to point out the technical impact on environmental performance of Timber frame construction as opposed to Steel & concrete
Designed for Longevity
A further component in the pursuit of an environmentally friendly house is design for longevity. We have so far looked at minimizing the energy needed to manufacture the building elements, efficient design to minimize the use of energy to ‘run’ the building during occupancy, and minimizing the environmental impact of building material production. ‘
Design for longevity is concerned with ‘appropriate’ design and construction methods, to increase durability, and to enable recyclability. Durability
A long life not only increases the value of a house, but is also economically and environmentally efficient. Appropriate design, detailing and specification are crucial factors in achieving durability. As organic building materials, timber elements have to be protected from biological damage (e.g. insect attack such as borers and termites, and fungal damage).
This can be readily achieved using standard building practices and detailing. Recyclability
What happens to a material when a house reaches the end of its life is an important factor, especially in the light of increasing depletion of non-renewable resources and the volumes of wastes which are dumped every day.
The environmental impact and amount of energy that is needed to disassemble a building once it has reached the end of its ‘life’, and the possibility to re-use building elements should be considered in the design of an environmentally friendly house.
Because the life of a building material can be far longer than that of the building, the components can be utilized for other purposes, that is, recycled. In contrast to other, inorganic building materials, timber can be fully reused. Intact timber elements can be easily employed for other building applications; heavily worn timber elements can be used as furniture, fuel, pulped for paper production, or as it is completely biodegradable, composted.
Energy Efficiency
Energy is another word for fuel - most commonly electricity, gas, oil or solid (coal) fuel. All fuel costs money in some form and the more fuel that can be saved with energy efficient buildings, the lower the running costs for building users and owners.
It is the building envelope that utilizes and/or controls the natural elements to assist in providing economic thermal comfort. For cool temperate climates some level of additional space heating will be required but, in most cases mechanical cooling will not be necessary.
The building envelope decisions which affect the 'economic comfort' requirement are the thermal resistance, thermal mass and thermal response of the roof, walls and floor and the thermal performance, natural lighting and ventilation characteristics of the windows and doors. These decisions are the major influences on the overall level of building heat loss, on the amount of solar energy collected and on the usefulness of this energy, i.e. on the space heating requirement. They also influence the level of direct power consumption for lighting and appliances.
And it is in the building envelope where the particular energy saving advantages of timber frame construction can be found. Frequently, the decision to build in timber frame is taken for reasons other than energy efficiency; for example, speed of erection, reduced site labor, dry construction, precision and accuracy of finished building or even cost. However, as energy efficiency continually becomes more and more important to clients and designers, this will become one of the major reasons for the choice of timber frame simply because the system has the ability to incorporate very high levels of thermal insulation.
Wall Cross Section
Thermal insulation is not the only energy criterion, however, and a view which is often expressed is that the low thermal mass of a timber frame fabric is such that solar gain cannot be effectively utilized. However, high thermal mass is not necessarily beneficial; but rather, the important factor is the provision of the right level of thermal mass in the right place to utilize solar gain. This can be achieved in timber frame without compromising the structural integrity of the system.
Thus considering all the factors discussed above timber frame structures have a relatively superior energy efficiency. We have prepared a chart to illustrate the performance between concrete, steel & Timber frame structures in respect to energy efficiency.
Wastes, By-Products and Environmental Effects
Wastes and by-products of timber manufacturing are minimal compared to other building materials. The ‘wastes’ resulting from the production of timber building materials are organic and are being utilized in a variety of ways including use as mulch and heat generation for kiln drying. Plantation and native forest management practices are constantly being improved to reduce environmental impacts based on detailed research and response to market demands.
Native forests and plantations provide wildlife and flora habitat, recreational opportunities, and can contribute to soil stabilization (especially on previously cleared land). Plantations (especially Palm tree plantations) have also been successful in ameliorating soil salinity in locations where the local water table has risen to the point where soils are poisoned.
The ph level of the soil in the surrounding areas of the development as well as the toxicity levels of the underground water table remains unchanged due to the minimization in the use of toxic chemicals & creation of dust & other air pollutants.

Reduced Consumption of raw Materials
The use of timber frame construction has the potential to reduce wastage rates on site, compared to traditional build methods.The manufacturing process has a wastage rate of less that 1.6%.
To make steel for example, raw materials have to be mined, transported and then combined together in factories also producing waste. By contrast, there is almost no waste in timber production – even sawdust is used for chipboard or paper production.
It is increasingly common practice to recycle and reuse what would otherwise be timber residue into new products and applications. The versatility of timber is no better demonstrated than in the variety of second life products it makes its way into.
The environmental benefits of such reuse are obvious - not only is the service life of the timber extended (and with it the need for a new product eliminated) but in addition, the carbon contained within the recycled timber is stored for the life of the new product.
When wood residue from timber processing cannot be recycled it can still be used to produce biomass energy. Biomass energy is a renewable energy, sourced from natural materials like wood, which is then generated into heat or electricity. The amount of waste generated from building a Wood residue used in energy production provides two 1500 sq.ft timber framed fold environmental benefits. Firstly, its use reduces house industry reliance on environmentally damaging fossil fuels, in turn preventing the release of long-term carbon store from sources that cannot be replenished. Secondly, the energy itself omits far fewer greenhouse gas emissions than typical alternatives.
