Statement of Work 1305M226Q0249

Sterling Field Support Center Road and Parking Lot Improvements

1.0 Purpose

The purpose of this Statement of Work (SOW) is to define the requirements, tasks, and performance standards for the repaving of designated roadways and parking areas at the National Weather Service (NWS) Sterling Field Support Center (SFSC). The work supports continued safe access for staff, visitors, and operational vehicles, including emergency response and forecast-critical transportation.

2.0 Background

The existing asphalt surfaces within the facility boundary have deteriorated due to age, freeze–thaw cycles, and routine operational use. Surface cracking, potholes, and drainage issues have been observed.

These conditions can pose safety risks to vehicles and personnel. Repaving is required to restore structural integrity, improve drainage, and prevent vehicle damage or personal injury.

3.0 Scope of Work

The Contractor shall furnish all labor, materials, equipment, supervision, and incidentals necessary to complete repaving of the roadway and parking lot areas identified in Section 3.1. Replace any damaged or worn parking blocks, damaged or collapsed drain culverts and curbing. All work shall comply with applicable federal, state, and local regulations, as well as NOAA/NWS facility standards.

3.1 Work Areas

• Weather Service Road from the east gate to the west gate

• SFSC Main building and Wind Tunnel parking areas and connecting road

• Wind Testbed access road

• Observation building access road and parking area

• Staging area

3.2 Required Tasks

The Contractor shall perform the following tasks:

3.2.1 Pre-Construction Activities

• Conduct a site assessment to determine surface conditions, and drainage patterns

• Measure surface area of the pavement that is to be repaved/resurfaced

• Identify subsurface failures requiring milling, excavation, or base repair

• Provide a detailed work schedule, traffic control plan, and staging plan

• Coordinate with NWS facility management regarding operational impacts

3.2.2 Surface Preparation

• Remove existing asphalt via milling to a depth of 1.5–3 inches, or

• Excavate and repair base material in areas of structural failure

• Clean and prepare surfaces for paving, including tack coat application

• Adjust or protect utility structures (manholes, drains, conduits)

3.2.3 Asphalt Paving

• Install new hot-mix asphalt (HMA) meeting state DOT specifications

• Compact asphalt to required density using appropriate rollers

• Ensure smooth transitions to sidewalks, building entrances, and adjacent pavement

• Verify slope and grade to maintain proper drainage away from structures

• Ensure utility structures are flush with the final paved surface

• Correct the above ground storm drain in front of the inflation building by raising the asphalt lever or lowering the storm drain.

3.2.4 Striping and Markings

• Repaint all parking stalls, handicap spaces, directional arrows, and fire lanes

• Apply thermoplastic or epoxy markings per local code and NOAA facility standards

• Install new wheel stops or signage as required

3.2.5 Site Restoration and Cleanup

• Remove all construction debris, excess materials, and temporary barriers

• Restore disturbed landscaping or soil areas

• Ensure all surfaces are clean and ready for operational use

4.0 Deliverables

The Contractor shall provide the following:

• Project Schedule with milestones and anticipated completion dates

• Traffic Control Plan ensuring uninterrupted access for NWS operational vehicles and personnel

• Material Submittals including asphalt mix design and marking materials

• Final Inspection Report Includes work that was completed, recommended care or maintenance and any deficiencies not covered by the SOW

• One-Year Warranty on workmanship and materials

5.0 Performance Standards

• All work shall meet or exceed state DOT paving standards and NOAA facility engineering requirements.

• The final paved surface shall be properly compacted, smooth and drain properly

• No standing water shall remain on paved surfaces after rainfall.

• Work areas must remain safe and accessible throughout construction.

• All deficiencies identified during inspection shall be corrected at no additional cost.

6.0 Schedule and Work Hours

• Work shall be completed within 30 days from Date of Award.

• Standard work hours for SFSC 0700–1700 local time, Monday through Friday.

• The access roads are shared with the Weather Forecast Office which operates 24/7. Any work impacting operational access must be coordinated at least 72 hours in advance.

7.0 Environmental and Safety Requirements

• Contractor shall comply with NOAA environmental policies, including stormwater protection and dust control.

• Fuel, asphalt, and chemical storage must follow EPA and state regulations.

• Contractor shall maintain an on-site safety plan and ensure all personnel use appropriate PPE.

• Noise, emissions, and vibration should be minimized when near operational buildings to avoid disruption to NWS operations.

8.0 Government Furnished Property / Access

• NWS will provide access to the facility, staging areas, and utility information.

• No government equipment will be provided for construction activities.

• Contractor personnel must comply with all facility security requirements.

9.0 Inspection and Acceptance

• The NWS Contracting Officer’s Representative (COR) will conduct interim and final inspections.

• Work will be accepted upon verification that all tasks meet contract specifications and performance standards.

• Any deficiencies must be corrected within 10 business days of notification.
