Statement of Work (SOW)

• Project Title: Office Storage Building Roof Replacement

Location: Steamtown National Historic Site (STEA), Scranton, PA

• Background:

The roof and drainage systems of the Office Storage Building have significantly deteriorated over time. A recent storm exacerbated structural and moisture-related issues, further compromising the roofing system's integrity. Due to the extent of the damage, full replacement of the roofing, flashing, and drainage components is required to prevent ongoing water intrusion and operational disruptions. The Steamtown National Historic Site operates a live railroad yard featuring coal-fired steam locomotives, restored cabooses, freight cars, and railroad coaches. Regular operations include passenger yard shuttles, mainline excursions, and commercial freight traffic. The 52-acre site includes active Locomotive and Restoration Shops, a Visitor Center, History and Technology Museums, a 250-seat Theater, and a fully operational Roundhouse and Turntable. The Contractor must perform all work in accordance with federal, state, and local codes and this SOW. The Contractor will provide all management, supervision, labor, materials, supplies, tools, and equipment necessary to complete the work. Daily cleanup and offsite debris disposal are required. The Contractor is responsible for inspecting the site, verifying dimensions, and familiarizing themselves with existing conditions before commencing work. Work should be carefully planned and executed to avoid damage to buildings, vehicles, equipment, and electrical systems. Material delivery access will be coordinated through Steamtown NHS.
