Forensic Engineering Analysis Of Vapor Transmission During Re-Roofing Project

Abstract

Roof Replacement Projects Are Routinely Conducted When A Building Is Occupied. Normal Safety Protocols That Control The Execution Of The Work And The Materials Used Are Specified In The Project Manual To Protect The Building Environment From Adverse Effects During The Course Of The Work. This Is A Case Where The Normal Protocols Were Insufficient To Protect The Building Occupants From Exposure To Vapors Present During The Construction Process. The Resulting Forensic Analysis Revealed That Elements Of The Building Construction Provided The Mechanism For Vapor Transmission That Together With Standard Preventive Measures Actually Created A Condition That Could Increase The Concentration Of Vapors Within The Building.
