We deliver bespoke, design-led cost efficient solutions optimised for the whole construction team, by maximising off-site manufacture in our production facility SES PRISM delivering our solutions which minimise onsite resources and interfaces assuring quality and customer satisfaction in a measurable, safe way every time.

Digital Engineering

SES has extensive experience with mechanical, electrical and plumbing (MEP) design and build projects with more than 80% of our projects being design and build. Our capability and expertise allows us to deliver projects from concept stage with a focus on developing safe, best value, low environmental impact solutions for our customers.

We have almost 50 specialists in our digital engineering team; comprising design, BIM and building physics engineering. A unique part of our business is our engineering management team which works with our customers and pre-construction teams to create innovative, affordable and value-driven solutions. Our commissioning, compliance and quality teams then ensure that every project has a Smart Landing.

Building Information Modelling (BIM)

SES was an early adopter of BIM, using 3D modelling on projects for over 15 years and embedding data into models since 2010. We are proud to be the first MEP contractor to achieve Building Research Establishment (BRE) BIM Level 2 Business Certification one month ahead of the government’s public sector project compliance deadline.

This will enable us to lead our peers into the critical industry changes and develop the skilled workforce to learn, understand and adopt these new developments as the industry grows.  We have a dedicated team of BIM specialists working with our design teams to develop building design in accordance with Level 2 BIM where appropriate. We strive to share our knowledge and experience in BIM with our clients ensuring there is a one team ethos through pre-construction to post completion.
