Mount Rainier National Park Facilities Maintenance Division

Statement of Work (SOW) Replacement of Overhead Garage Doors – N101 & N201

PMIS Project No.: 323461 Performance Period: August 1, 2025 – December 31, 2025 Prepared by: Frances Holmgren, Facilities Operations Specialist Date: July 10, 2025

Project Overview

The Nisqually Entrance Historic District, listed on the National Register of Historic Places (NRHP Ref. No. 91000172), includes distinguished National Park Service Rustic structures constructed between 1926 and 1934. Among these are Building N101 (the single-bay employee housing garage) and Building N201 (the six-bay service garage), both contributing resources that retain original site grading, historic plant palettes, and stonework. This project provides for the full removal and off-site disposal of existing overhead garage doors at these structures and the installation of new 16-gauge steel sectional doors with a dark-brown baked-on finish, 20,000-cycle torsion springs, no openers, keyed locking devices, and no in-panel glazing. All work shall comply with the Secretary of the Interior’s Standards for Rehabilitation, NPS Director’s Order 28, and NPS Preservation Briefs 14 & 47;

accommodate remote-access and weather-window constraints; maintain uninterrupted egress; and integrate environmental protections (erosion/sediment control and vegetation preservation), utilizing a staging area provided by the COR.

• Transport and dispose materials off-site in compliance with federal and state environmental regulations.

2. Track Preservation

• Retain and inspect existing galvanized-steel track assemblies.

• Clean, adjust, and lubricate track and rollers to manufacturer’s specifications.

3. New Door Installation

a. Door Assembly

• Type: Sectional commercial overhead door

• Construction: 16-gauge steel panels; brown baked-on exterior finish

• Springs: 20,000-cycle torsion springs

• Garage door openers: None required

• Model: Overhead Door Company Model 416 (or equivalent, subject to COR approval)

• No alteration to original framing, bay openings, site grading, historic plantings, or stonework.

IV. Access, Constraints & Environmental Factors

A. Remote & Weather Access

• Access Route: Nisqually Park Road; coordinate vehicle passes and tool deliveries with COR.

• Weather Windows: Conduct exterior work only in dry conditions; suspend work if precipitation or temperatures below 32 °F are forecasted.

B. Employee Housing Access

• Coordinate door-replacement schedule with occupants of N101 to maintain 24-hour egress and minimize noise and dust impacts.

C. Environmental & Safety Requirements

• Erosion Control: Install silt fencing or hay-bale barriers to prevent sediment runoff, as needed.

• Historic Landscape Vegetation Protection: Lay ground-protection mats; avoid disturbance of historic plant palettes.

• OSHA Compliance: Provide fall protection, barricades, and emergency access per 29 CFR 1910.

D. Staging Area

• A staging area shall be provided by the COR.

• Requirements: Use spill-containment for paint, solvents, and lubricants; avoid historic features; restore to pre-work condition.

V. Execution & Testing

• Installation Sequence: Verify rough openings; install track assemblies; hang door panels; fit springs, cables, seals, and locks.

• Testing: Cycle each door at least 20 times; verify balance, smooth operation, and weatherseal performance; adjust hardware as necessary.

• Protection: Shield adjacent siding, windows, and landscape features throughout the work to prevent damage to historic structures.

VI. Deliverables

• Manufacturer’s product data sheets and shop drawings for doors, springs, and locking hardware.

• Daily logs documenting safety, environmental controls, and work progress.

• Final inspection checklist signed by Contractor and COR.

• Record drawings (PDF) showing as-installed door locations and hardware.

VII. Performance Period

• All work shall be completed between August 1 and December 31, 2025, with field activities scheduled to avoid peak visitor periods and adverse weather.
