Unit 6: Building Technology in Construction
P1 – explain the different forms of low-rise construction currently used for domestic and commercial buildings.
Timber frames – timber is quick to construct, a timber frame can be partly pre-cut, modulated and built to precision and therefore the build time is much quicker than for a brick build. Time is also saved due to a much cleaner site since less building debris is around. A typical house can be weather-tight in less than 5 days. You can use timber frames to construct domestic and commercial buildings. Timber frames take 2 weeks to construct but they can be sped up. Once the timber frame structure is in place, other tradesmen have access to the house to work, shielded from the weather.
Steel frames - They are very quick to build at site, as a lot of work can be pre-fabricated at the factory. They are flexible, which makes them very good at resisting dynamic (changing) forces such as wind or earthquake forces. A wide range of ready-made structural sections are available. They can be made to take any kind of shape, and clad with any type of material. A wide range of joining methods is available, such as bolting, welding, and riveting. They are very strong and can hold a large amount of weight. However, steel frames have disadvantages such as, they lose strength at high temperatures, and are susceptible to fire. They are prone to corrosion in humid or marine environments.
This is what a steel framed low rise domestic building looks like. It is strong and malleable.
However, as it is welded into place, environmentally it isn’t very good for the environment as it isn’t reusable. Steel frames are usually for all types of buildings, for example, warehouses, agricultural barns, commercial and domestic housing. The disadvantage of using steel is that it is costly, and that a high level of accuracy is needed to construct the frame. The advantages are Large open areas can be made due to load bearing ability of...
