Measured Building Surveys

What is a Measured Building Survey?

Measured building surveys provide a detailed and highly accurate representation of a building’s structural features – typically including floor plans, elevations, and sections. They are based on precise measurements taken on-site using a variety of surveying techniques, principally 3D reality capture technology, which allows us to quickly and efficiently document the size, shape, and layout of a structure.
Our measured building surveys are delivered to client specification and, as a minimum, comply with the standards set out in RICS guidance note Measured Surveys of Land, Buildings and Utilities – 3rd Edition.

When do I need a Measured Building Survey?

Measured building surveys are commonly required for development, renovation, conservation, or legal and property documentation purposes, such as Land Registry-compliant plans. The resulting plans or models can then go on to inform further works, help with upkeep and maintenance, or aid in transactions or leasing.
A measured building survey is appropriate whenever a millimetre-accurate plans or digital representation of a building are required.

I wanted to take a moment to share some very positive feedback regarding Jamie, currently supporting the works at Westbury Viaduct. Since joining the team, Jamie has made a noticeable and genuinely positive difference. His proactivity, strong work ethic, and engaged communication with the client have all stood out. He has integrated quickly and effectively into the team, and his approach has already helped strengthen collaboration on site. I felt it was important to highlight the value he is adding, and to let you know that his contribution is very much appreciated. We look forward to continuing the momentum as we progress with the successful installation of the parapets. Thanks again, and please pass on our appreciation to Jamie.

The survey data we received last night was exactly what we needed. It showed us that the existing access road doesn’t match our construction drawings, which is a significant find for us. Thanks again for managing to rearrange your schedule; it’s really helped us stay on track with our tight deadlines.

I am more than happy to vouch for the quality and timeliness of Interlocks Surveys work at St Bartholomew’s Hospital and can confirm that their ways of working were appropriately considerate of the nature of St Barts as a Grade I listed heritage asset.”

That is excellent thank you. Thank you and the team for your hard work on this. I appreciate it was a whopper of a project to get done given the sheer scale of the site and all the off site highways to considered.
