If are you carrying out a house extension, loft conversion or load bearing wall removal then it is likely you will require a steel beam or two. These beams will need to have calculations submitted to your Local Authority Building Control for their approval. We prepare these calculations for Homeowners and Builders. The calculations are carried in accordance with the most recent British Standards. All calculations produced using the latest computer software. Design work covered by Professional Indemnity Insurance. Quick turnaround! Timber and flitch beam calculations can also be prepared!
