Project oversight is a key component to the turn-key project planning process, but can also be one or several stand-alone tasks. Before the work begins, a review and subsequent approval of the critical project documentation sets the tone and assures that all communications of the work scope and project intent are understood by all of the parties. During the work, visual inspections, material testing, and the knowledge that an experienced third party is present and monitoring the foam installer’s work can assure a safe, quality installation. Post-installation material quality control testing and monitoring of environmental conditions during the cure period, as well as verification of IAQ and CAZ safety are the final steps in a comprehensive closeout process.
