Providing building owners, managers and insurers with support to mitigate the risks of unacceptable building envelope performance.

Improve the accuracy of your planning and reduce the costly damage of envelope failures as you manage your building envelope assets. 


Whether you are an owner, manager or insurer considering an addition to your building portfolio or assessing your existing building stock, we can give you confidence in your building planning and help you get maximum service life from your installed envelope systems.

Our technical assessment services include condition surveys and forensic investigations.

Condition surveys provide value by:

  • Identifying envelope components that have deteriorated and present health and safety hazards demanding immediate attention
  • Identifying envelope conditions with financial impact to be considered during due diligence in a contemplated building purchase
  • Identifying the timing and capital spending required to maintain an envelope system during its life and to replace the system at the end of a normal life cycle

Forensic investigations provide value by determining the cause and remedial work solutions for premature performance problems, such as:

  • Water leakage through roofs or windows
  • Condensation on interior surfaces and dangerous icicle formationson exterior surfaces
  • Thermal control causing occupant discomfort and/or frozen water pipes
  • Corrosion of fasteners or spalling of masonry
  • Pest infestations, e.g., cluster flies, lady bugs, affecting tenant satisfaction

With the experience and expertise gained from decades of laboratory testing of a wide spectrum of building envelope systems, our dynamic team of highly specialized staff can provide technical assessment services for your projects around the globe.
