Addendum to Statement of Work – Roof Replacement at Dingmans School and Jackson House
This addendum modifies the roofing material specifications for a roof replacement project at two historic structures—Dingmans School (North Zone) and Jackson House (South Zone)—located within the Delaware Water Gap National Recreation Area. The original Statement of Work specified fibrous cement roof tile for Dingmans School and natural or in-kind slate roofing for Jackson House. The addendum permits the Contractor to substitute EcoStar synthetic slate roofing at both structures as an alternative, provided the synthetic slate is selected to closely match the existing roofing at each building in color, profile, texture, and overall appearance.
The Contractor must submit proposed EcoStar product data, color selections, profiles, texture samples, and warranty information to the Contracting Officer for review and approval, with technical coordination through the Contracting Officer's Representative. The approved product must be installed per manufacturer's written instructions and remain compatible with the specified roof pitch, underlayment, flashing, fasteners, roof penetrations, and historic building conditions. Any changes to the roof assembly, fastening pattern, decking, ventilation, flashing, or associated components necessitated by the synthetic slate system require prior written approval from the Contracting Officer. All other requirements from the original Statement of Work remain unchanged and in full effect, including removal and disposal, asbestos testing, roof decking repairs, underlayment, copper flashing, gutters, snow rakes, roof boots, painting, safety measures, and compliance with Department of the Interior and National Park Service historic preservation requirements.
