Submit written manufacturer inspection reports identifying observations, deficiencies, required corrective actions, and final acceptance necessary for issuance of the specified manufacturer warranty.

Correct manufacturer-identified deficiencies before final acceptance and warranty issuance.

15.4 Government Inspections

Government review or inspection does not relieve the Contractor of responsibility for complying with the contract.

Correct rejected or nonconforming work at no additional cost.

15.5 Final Cleaning

Remove debris, metal shavings, loose fasteners, sealant residue, protective films, temporary materials, and construction waste. Clean roof, gutters, grounds, and adjacent areas. Perform a final sweep for screws, sharp metal, and other hazards.

16. SAFETY AND SITE REQUIREMENTS

16.1 Provide portable sanitation facilities unless otherwise approved.

16.2 Submit a Site-Specific Accident Prevention Plan (APP) before mobilization.

16.3 Provide site-specific fall protection, rescue procedures, competent-person designations, hazard communication, heat-stress controls, electrical safety, ladder safety, and daily Activity Hazard Analyses/Job Hazard Analyses as required.

16.4 Provide scaffold, crane, lift, hoisting, and rigging plans when such equipment is used and when required by applicable standards.

16.5 Maintain 100 percent fall protection/tie-off where required by applicable standards and the approved plan.

16.6 Secure materials and equipment against wind. Do not store loose roofing panels or sheet metal in a manner that can become airborne.

16.7 The Government may stop work presenting an imminent danger or unacceptable risk. Such action does not relieve the Contractor of its safety responsibilities.

16.8 Limited use of existing Government electrical power and water will be permitted without charge where reasonably available and adequate for the intended construction use, subject to prior coordination and approval by the COR. The Contractor shall provide all temporary cords, hoses, connections, distribution equipment, protection, and incidental equipment required for its operations. The Government does not guarantee utility capacity beyond existing available service.

17. ENVIRONMENTAL AND RESOURCE PROTECTION

Comply with all project-specific National Park Service environmental compliance requirements and instructions provided by the Government. Protect vegetation, wildlife, cultural resources, soils, drainage, and adjacent habitat from construction impacts.

Protected species potentially encountered may include gopher tortoise, eastern indigo snake, beach mouse, and other species identified by the Government. The list is not exhaustive and does not replace project-specific environmental compliance documents.

• Immediately stop affected work in the vicinity of observed protected wildlife.

• Notify the COR or designated park representative.

• Do not capture, handle, feed, harass, relocate, or otherwise disturb wildlife unless specifically authorized.

• Prevent construction debris, sealants, fuels, wash water, and other contaminants from entering habitat, soil, stormwater, or waterways.

• Provide spill prevention and cleanup materials appropriate to the work.

• Contractor shall prevent the introduction or spread of invasive plant species by ensuring all construction vehicles, equipment, tools, and materials entering the park are clean and free of soil, seeds, plant material, and other biological debris. Equipment found contaminated shall be cleaned at an approved off-site location prior to entering the project area.

• Keep staging, storage, parking, and access within approved disturbed areas.

• Government-approved staging and laydown areas will be designated adjacent to each structure. The

Contractor shall coordinate the specific limits and configuration with the COR before mobilization and shall confine staging, parking, storage, dumpsters, and equipment to approved areas.

18. SUBMITTALS

Submit required documents sufficiently in advance to permit Government review and to avoid delay. Do not procure or fabricate permanent roofing materials until required product, shop drawing, field-verification, and engineering submittals affecting those materials have been reviewed and accepted in accordance with the contract. Government review does not relieve the Contractor from responsibility for errors, omissions, coordination, or compliance.
