SCAFFOLD DESIGN CALCULATIONS

Calculations
Scaftec provide calculations to substantiate every design. This can range from hand calculations (to check the feasibility of a proposal) to fully computer-produced calculations (to accompany working drawings).

For larger or more complex designs (such as temporary roofs and/or large, free-standing, sheeted scaffolds) the frame analysis package P-Frame is used:

p-frame design calculations

Calculations for larger jobs are also produced using Microsoft Excel, and with bespoke software developed for specific jobs and clients. This allows for a consistency of presentation that meets the requirements of demanding clients.

All calculations are produced in accordance with the relevant regulations, guides and codes of practice:
