Assessment
Our substantial expertise includes the assessment and restoration of building facades and envelopes. This is often a complex process, not only because duress is usually discernible only after problems are well advanced, but because there are an inherent number of variables to consider in most investigations.

Crosier Kilgour & Partners have conducted a wide range of assessments, from 250-year-old historical structures to new facilities experiencing moisture intrusion. Only once the causes of the observed duress have been identified can we begin to develop a cost-effective program of remediation.

We carry out the assessment process in a number of ways, including innovative techniques that we have developed in-house for the exclusive use of our clients:

• Visual assessments are conducted from bosun’s chair, swing stage, scaffolding or by rappelling down the face of the building.
• Openings are made through exterior cladding surfaces, flashings or through interior finishes to access and observe the interior of the building envelope. Use of our boroscope limits the size of the openings required.
• Thermographic scans can reveal areas of inadequate, wet or deteriorated insulation.
• Advanced computer modelling, coupled with on-site observations, provides fundamental knowledge of the performance of an existing envelope.
• Using instrumentation developed in-house, real time measurements are taken periodically to understand what pressures, moisture loads and forces are at work on a building envelope over time.
• Testing procedures, also developed in-house, assess the performance of remediation options on existing buildings in their as-constructed state.
• Impact echo test procedures, originally developed at Cornell University to assess motor vehicle-traffic bridges, have been modified by Crosier Kilgour & Partners to evaluate masonry and stone-cladding panels.
