During the performance of the work, the contractor shall provide adequate professional supervision and quality control to assure the accuracy, quality, completeness, and progress of work. Work will be scheduled so that outdoor air temperatures during the installation of the air source heat pump are not below 50 degrees Fahrenheit.

This requirement includes one site visit for the purpose of site inspection, and one follow up trip for the purpose of installing the new mechanical systems and completing the start-up, commissioning, and control sequencing. It is the responsibility of the contractor to verify that all the information provided is accurate.

All work is to be completed as specified, manufactures specifications, and other award documents, as well as all applicable codes and industry standards.
