Investigating Large-Scale Building Envelope Leakage: Ten Practical Tips for Litigation Projects

One of the most common complaints about buildings is water leakage through the building envelope. A well-planned investigation can efficiently uncover the root causes of water leaks, a critical step in designing effective repairs. Investigations for litigation often involve special protocols and coordination with more parties than for non-litigation situations.

Reviewing available documents, having a sound basis for testing, and understanding the requirements specific to the project will help the investigation run smoothly. Communication protocols will keep all parties informed of the planned testing activities. Understanding the ultimate deliverable will ensure that sufficient data is collected during investigation.
