Residential
Modular Buildings
Lightweight structures such as flat pack modular buildings are evolving as a quality construction alternative. They are particularly attractive for clients who are looking for a fast simple and cost effective alternative to conventional construction methods.
They can be installed in a matter of days rather than weeks or months. As the buildings are lightweight particular attention needs to be given to the foundation system as wind loadings may have a significant affect.
In coastal and cyclonic regions the foundation system will act in tension to resist uplift forces induced by wind. Screwpiles provide a fast and simple solution. The number and size of screwpiles required for a building is determined by the combined uplift load calculated by combining the following data:
- Structures sub-floor system and its ability to span based on allowable deflections.
- Wind Region and Terrain Catagory
- Size of building (sail area)
- Floor height from ground level
- Adjoining structure influence
- Ground conditions (soil density and contours)
- Environmental conditions (corrosion allowances)
These structures have a sub-floor system consisting of UB beams or C-Perlins. Each require consideration as to the connection method (interface) between the building sub-floor systems and the screwpile. Examples showing the types available are shown alongside.
