We’ve joined forces with Local Authority Building Control (LABC) to revolutionise the Registered Construction Details (RCDs), aligning them with thousands of products to make procurement simpler.

Our RCDs

We include RCD’s as part of all SAP assessments, to help translate your design through to the build stage of the project. Using your designs, we evaluate which RCD’s are most suitable for your construction method and include them to support you in designing out thermal bridging issues.

What’s so unique about our RCDs?

We’ve enhanced the original RCDs, by integrating a vast array of product lines into each, so you have plenty of options to choose between to assist you in minimising cold spots in your build.

  • Each RCD contains calculated values, points to watch and a vast array of product options that allow you to achieve the necessary values
  • If you opt for a Build Aviator SAP assessment, the relevant RCDs for your build will be included as standard
  • Each RCD includes a check sheet for additional support
  • Evidence for Building Control and Clerk of Works during on-site inspection making sign-off simpler Approved by the LABC
