Structural calculations demonstrate that a building or structural element can safely support the loads applied to it. These calculations consider factors such as weight, occupancy, wind, snow and material strength. They are required by Building Control for works including extensions, steel beams, foundations and new builds. Structural calculations ensure compliance with UK regulations and provide assurance that the design is safe and suitable for construction. They also help contractors understand how elements should be installed correctly. Without proper calculations, projects risk non-compliance, safety issues and costly remedial works.
