Welcome to Keystone Structural Engineering (SW) Ltd, we provide a friendly professional approach to quality structural design service at a competitive price throughout South Wales. We principally specialise in the private and domestic sector but can provide design to the commercial or other areas of the market if required.

With extensive experience in structural engineering design we are able to prepare structural calculations, drawings and specifications for you or your contractor to build from. Our structural packages range from the simple steelwork beam calculation, through the full 3D analysis of major structures.  To ensure a speedy design process we have some of the latest design software available which is fully compliant with all the British Standards.

We also have considerable experience in the design and detailing of the latest drainage SUDS (Sustainable Urban Drainage Systems)  techniques available. Where attenuation or soakaways systems are required we can fully design and detail the most cost effective solution. We can also carry out on site infiltration testing in compliance with the BRE365 requirements.

We provide a free quotation service within 24 hours of receipt the architect's proposed scheme. Should the quotation be successful and we are formally instructed to progress, we'll advise you when the design package will be ready for issue, which is normally within a week.
