OVERVIEW The following presents the construction-phase Roof Commissioning Plan (RCP) and Specifications for the roof replacement projects at the RK Finn Elementary & Leeds Elementary Schools located in Northampton, Massachusetts. The plan defines the procedures for the commissioning of the roof replacement project and describes the functional performance tests to be performed. The purpose of the RCP is to provide a process for independent third-party verification that the installed performance of the roof meets or exceeds the minimum performance requirements set forth by the Owner’s Project Requirements (OPR) and Contract Documents; to help verify that the applicable roof systems are installed according to manufacturer’s recommendations, design requirements, and to industry accepted minimum standards; and to confirm that installing contractors provide adequate quality control. This plan will be updated throughout the commissioning process as necessary to further clarify the commissioning requirements and meet the OPR and design intent. The requirements of this RCP shall in no way relieve the Contractor, Designer of Record (DOR) and other parties to this project of their respective contractual obligations to the Owner for meeting the specified performance levels in the design and construction of this project. 1.1 Owner’s Project Requirements (OPR) The work at RK Finn Elementary & Leeds Elementary Schools is part of the Massachusetts School Building Authority’s (MSBA) Accelerated Repair Program. As such, all repairs must be in accordance with the Massachusetts Stretch Energy Code (MSEC). The RCP is based on the requirements of the MSEC, the design drawings and specifications, and the corresponding approved submittals and shop drawings. Raymond Design Associates, Inc. remains the DOR for the building envelope systems and maintains discretion over the final design and construction. Our construction phase commissioning services are intended to help verify that the construction is in accordance with the MSEC and Raymond Design Associates, Inc., final design and approved submittals. 1.2 General Project Information RK Finn Elementary School The scope of work for Areas “A” & ”D” includes the installation of a “go-over” (Areas “A” & “D”) roof system over the existing roofing system (membrane and wood fiberboard insulation to be removed to existing rigid insulation board). The new roof system will be an .090” adhered EPDM roof system with a new ½” cover board (adhered in insulation adhesive) and 1” layer of rigid insulation board insulation (mechanically fastened) over the existing insulation that is to remain. New ¼” per slope tapered crickets will be installed to provide positive slope to roof drains The scope of work for Roof Area “E” includes the complete removal of the existing membrane, insulation down to the steel deck. The new roof system will be an .090” adhered Roof Commissioning Plan Roof Replacement Project RK Finn & Leeds Elementary Schools Northampton, MA RBA Project No: 2015022.00 3 EPDM roof system with a new ½” cover board (adhered in insulation adhesive) over tapered polyisocyanurate rigid insulation board insulation. The work also includes the reuse of existing roof drains and removal and replacement of existing roof drains on other roof areas, modification and reuse of existing ladders, new roof access ladders, installation of walk pad, prefinished metal roof edge and copings, removal and reinstallation of roof top equipment. A 30 Total System Warranty will be provided for the new roof system. Repair of the existing structural steel is also included.
