Frequently Asked Questions from Ipswich Clients
Do I need calculations to remove a load bearing wall?
Yes. Any structural alteration that affects how loads are carried will usually require structural calculations and often drawings. Building Control officers rely on these documents to confirm the work is safe.
Can you work with my architect and builder?
Absolutely. We collaborate with architects, builders and other consultants to make sure our designs integrate seamlessly with the broader project. Clear communication helps prevent misunderstandings on site.
How quickly can I expect my calculations?
Timeframes depend on the size and complexity of the project. For straightforward domestic alterations we usually issue calculations within one to two weeks of receiving all necessary information. We confirm timescales when we send our fee proposal.
Are you insured and professionally regulated?
Yes. We are chartered engineers and hold appropriate professional indemnity insurance. Our work follows guidance from the Institution of Structural Engineers and complies with relevant Building Regulations.
