Structural calculations are the engineer’s proof that the beams, columns, foundations and floors in your project can safely carry the loads placed on them. Building Control will ask for them before signing off most structural work, and your builder needs them to order the right steel and build with confidence. Canterbury Surveyors produces clear, Building Control-ready structural calculation packages for homeowners, builders and architects across Canterbury, Kent and the surrounding counties.

Are structural calculations necessary for you?

If your project changes how the building carries weight, the answer is almost always yes. Removing a load-bearing wall to open up a kitchen, forming a new opening for bi-fold doors, converting a loft or garage, or building a rear or side extension all redistribute loads the original structure was never designed to take. Calculations size the new members correctly and demonstrate to Building Control that the finished work meets Part A of the Building Regulations.

What our calculation packages cover

Each package is prepared and checked by a chartered engineer and tailored to the work in hand. Typical instructions include:

• Steel and timber beam sizing for wall removals and new openings
• Loft and garage conversion calculations for new floors, roofs and staircases
• Extension design, including foundations, lintels and roof structure
• Padstone and bearing design where new beams land on existing walls
• Assessment of the existing structure that will carry the additional load
• Calculations supporting solar-panel and other roof-mounted installations

From design to Building Control sign-off

We work from your drawings, or alongside your architect, to produce a calculation pack and structural notes formatted the way Building Control surveyors expect to receive them. Where the work is straightforward, the calculations can often be issued within a few working days on a fixed fee agreed in advance. A site visit is arranged only where the existing structure is concealed or unusual and needs to be inspected before the design can be finalised, so you are never paying for a visit you do not need.
