Any building, regardless of age, can be subject to poor performance of the building envelope. CDC provides observation and diagnostic testing to determine causes of unwanted air and water infiltration; condensation and/or frost formation; undesirable in-service noise; and failing glass, stone, brick, sealants, or other elements.

CDC diagnoses performance issues:

• Establishes probable cause of poor performance, via:
  • Observation from the ground, from aerial personnel lifts or swing stages (provided by others), and/or from accessible roof levels.
  • Review of existing architectural drawings, and shop drawing documents if available
  • Review of previous condition studies, reports, or other relevant Client documents
• Performs a range of tests and/or soundings, and (if justified) observe limited disassembly in the vicinity of a failure, to further clarify the mode of failure.
• Prepares a detailed, written, photographic report of observations and findings.
   

After mode of failure is established, CDC:

• Develops procedural recommendations, details and specifications for repair/remediation.
• Performs bid review and contract administration for quality assurance during the repair cycle.
• Provides site observations and written photographic reports as part of field quality assurance program during repair.
