About this file

This is a Statement of Work (SOW) for roof rehabilitation services at USDA Forest Service facilities located in Lincoln National Forest, Ruidoso, New Mexico. The project involves installing Thermoplastic Polyolefin (TPO) roof recover systems over seven existing buildings with metal and flat tar/built-up roofs, covering approximately 15,849 square feet total. The contractor must furnish all labor, materials, equipment, supervision, and incidentals necessary to complete the work, including full replacement of gutters and downspouts with corrosion-resistant materials. Work scope includes inspecting and preparing existing roof systems, installing manufacturer-approved TPO recovery boards and membranes with heat-welded seams, installing TPO flashing at all penetrations and transitions, and coordinating around two buildings with existing rooftop solar panel systems by either performing work around them or temporarily removing and reinstalling them without additional cost to the Government.

The performance period is 160 calendar days from Notice to Proceed. Contractor quality control requirements include submitting product data and installation details prior to mobilization, with the Contracting Officer's Representative conducting inspections at preparation completion, recovery layer installation, and final membrane/gutter/solar coordination stages. Any work not meeting contract requirements must be corrected at no additional cost to the Government. Required deliverables include a project schedule, manufacturer product data, as-built roof and gutter layouts, and final completion documentation. All work must comply with TPO manufacturer requirements, applicable ASTM standards, USDA Forest Service construction standards, and all applicable OSHA regulations and Forest Service safety requirements.

Project Title: Roof Rehabilitation – TPO Recover Systems Agency: U.S. Department of Agriculture (USDA), Forest Service Forest: Lincoln National Forest Location: Ruidoso, New Mexico

1.0 PROJECT OBJECTIVE

The objective of this project is to rehabilitate existing roofing systems at USDA Forest Service facilities by installing Thermoplastic Polyolefin (TPO) roof recover systems over existing metal and flat (tar/built-up) roofs, along with full replacement of gutters and downspouts.

The work shall extend roof service life, improve watertight integrity, and integrate with existing building systems, two roofs have current solar panels established, while minimizing disruption to Forest Service operations.

The Contractor shall furnish all labor, materials, equipment, supervision, and incidentals necessary to complete the work.

Recovery Board / Separation Layer Install approved recovery board, insulation, or separation layer as required by the TPO manufacturer to provide a continuous substrate.

TPO Membrane Installation Install a fully adhered TPO membrane over all roof areas.

Heat-weld all seams to form a continuous watertight assembly.

Flashing and Detailing Install TPO flashing at all penetrations, walls, curbs, parapets, and transitions.

Integrate roof system with existing roof edges, drains, and penetrations.

2.4 GUTTERS AND DOWNSPOUTS

A. Remove and replace all existing gutters and downspouts on buildings included in this contract.

B. New gutters and downspouts shall be corrosion-resistant, properly sized, and securely attached.

C. Downspouts shall discharge away from building foundations and coordinate with existing drainage.

2.5 SOLAR PANEL COORDINATION

A. Some buildings include existing rooftop solar panel systems.

B. The Contractor shall:

Perform roofing work around existing solar panels, or Temporarily remove and reinstall solar panels as required to complete roofing work.
