GMC design team took the clients drawing prepared by an architects practice and made considerable savings for the client by applying our build knowledge. 2 Main items were drainage & service arrangement and the foundation arrangement. These savings were passed directly onto the client. Home extension Berwick upon Tweed Northumberland

 


 

IMG_1686 (Small)Another saving for the client here, the engineer specified a Steel RSJ mid support and joists running front to back. By Turning joists to span left to right and up-grade the joist size to 75×220. The client again made a saving as the additional cost of the up-grade timber was considerably less than the cost of the Steel RSJ. Aesthetically the client was pleased as they did not like the idea of the steel boxing that would be required around the steel work. Using the GMC method there is a flat celling.
