About Structural Design
Structural design is the methodical investigation of the stability, strength and rigidity of structures. The basic objective in structural analysis and design is to produce a structure capable of resisting all applied loads without failure during its design life.
Basis of structural design
Structural analysis and design calculations are carried out in accordance with British and European Standards and Codes of Practice.
Typically these would be:
- British Standards
- BS6399 Loadings for Buildings
- BS5950 Structural use of steelwork in building
- BS8110 Structural use of concrete
- BS5628 Code of practice for the use of masonry
- BS5268 Structural use of timber
- BS8002 Earth retaining structures
- BS8004 Foundations

Detailing and design of piled or reinforced foundations.

Dimensional survey of the site or existing building. Where architectural drawings or other information is provided dimensions will be taken from them or scaled from.
Temporary works design. The design of temporary supports to allow the permanent works to be installed is normally carried out by the contractor. We are able to carry this out is requested and agreed separately to the design of the permanent works.
