Intrusive Survey Facilitation in London and the South East
At Simbi Ltd, we provide intrusive survey facilitation for buildings across London and the South East. Our team supports appointed consultants and architects with access and opening-up works. This allows specialists to inspect areas concealed behind the external finish.
Supporting External Wall Investigations
External finishes can hide important details of a building’s construction. Intrusive surveys therefore involve opening up selected areas for closer inspection.
To support these investigations, our team provides access for the appointed specialists. We hold relevant access accreditations and work alongside consultants and architects to support the agreed survey scope.
For background on external wall fire risk appraisals, read the RICS explanation of PAS 9980.
Our Approach to Intrusive Survey Facilitation
Before work begins, we coordinate with the project team to understand where access and opening-up works are required. We then plan our activities around the survey requirements.
Throughout the process, we work closely with the appointed specialists so they can reach the areas they need to examine.
