Structural calculations

Structural calculations work out the loads on a part of the structure and then check whether it is strong enough to support them.  They are needed to make sure that the structure is safe.  They are often asked for by Building Control when a Building Regulation application is made.  This may be as part of a new build or an alteration.  They don’t make much sense to the average person but they can be understood by another engineer.

You can order all the structural calculations you need for your project on this website.

We cover all types of residental alterations and also many commercial projects.  Our services are all based on fixed prices.
