Heritage High School

Conyers, Georgia

Heritage High School was constructed in 1976.  Its original roof assembly consisted of a built-up roof.  However, a sprayed polyurethane roof system had been applied over the original roof and was in various stages of failure.  Raymond Engineering was retained as a roof consultant to provide re-roofing design, construction administration and quality assurance inspection services.  Additionally, the skylights over the Commons Area required replacement due to a failure of gaskets and glazing.

The new roof systems consisted of the removal of the existing roof systems, application of new roof insulation, so as to meet current energy code requirements, installation of a granule surfaced modified bitumen built-up roof, flashings and metal flashings, and the replacement of several internal roof drains.

The relatively short roofing window had a very significant impact upon our approach to this project.  Bidders were informed that the project schedule was critical in that all tear-off and installation of roofing materials, with the exception of sheet metal and new skylights, had to be completed before teachers and students returned from the summer break.  Our project team managed the schedule at each weekly progress meeting and in conjunction with reviewing our Registered Roof Observer’s daily reports.

The relatively short summer schedule dictated the overall project requirements.  As a result, the progress of the work was monitored on a daily basis to insure that the work progressed so as to meet the clients’ schedule requirements.  Due to the high daytime temperatures, arrangements were made to allow work to take place at night, so as to improved production.
