August 7, 2026

1.0General

1.1 Background:

This project is for the National Weather Service (NWS) Weather Forecast Office (WFO) in Brownsville, TX, (BRO). The main office requires full replacement of its sewage drain lines.

Numerous clogging and backups have occurred and during a recent cleaning, breaks as well as build up have been documented.

1.2 Objective:

Replace the sewage drain system to full functioning condition. NWS needs replacement of the drain line connecting the men’s and women’s restrooms, replacement of the drain line connecting the kitchen and replacement of the main drain line from the building. The NWS requests a turnkey start-to-finish project necessary to complete the replacement while ensuring minimal interruption to the facility’s 24/7 mission-critical operations. This includes building a temporary wall to allow the equipment room to remain operational throughout the duration of the project.

1.3 Applicable Documents

The Contractor must adhere to all current local prevailing wages, as mandated by the Davis-Bacon Act (DBA) of 1931. Other relevant documents, if requested, are specified in the Deliverables section (Section 8.0).

1.4 Value Engineering

NWS assumes a full drain line replacement, which requires slab removal/restoration or alternative access methods (e.g., below-grade tunneling). Quoters may propose alternative technical execution methods provided the proposed solution satisfies all functional, structural, and mission-continuity requirements outlined in this PWS. All proposed methods will be evaluated on a Pass/Fail basis against the Technical Acceptability factors in the solicitation.

2.0Specific Requirements/Tasks

The Contractor is responsible for all labor, tools, equipment, materials, supervision, management, sub-contractors, licenses and permits, site preparation, execution, and final restoration. It is Required that any contractor who will be submitting a quote as the Prime contractor, schedule a site visit and sign-in for physical inspection of existing conditions to ensure all offerors are quoting on the same scope of work. Due to the location of essential equipment, other means of restoration may be necessary (below grade tunneling) to reach the piping. If needed as-builts drawings are available on site for reference. The contractor will verify all piping dimensions, slope and grade. The NWS staff will notify the contractor of any recent issues at the site visit.

2.1 General Requirement

● Perform a full diagnostic testing of piping to include, video inspection, mapping and documentation of all findings (pre and final) per location and to include the full function of sewage lift station.

● Restore the facility and all affected areas- including flooring, walls, pavement, landscaping, fencing and/ or relocated equipment to their original condition or better.

● Prior to disconnecting any equipment, the contractor along with NWS will survey and test the existing equipment. After reviewing the equipment, the contractor will document any discrepancies found during the review. The contractor will submit a report identifying the discrepancies for NWS approval.

● Disconnect, disassemble, move and reconnect/replace all obstructions preventing access to the drain line piping. Mark locations of each item for reinstallation. Disconnected equipment can be stored onsite. Coordinate on-site location with NWS Staff.

● Reinstall and reconnect all equipment relocated in the execution of the work. Coordinate with NWS on specific locations of all equipment and wiring.

● Dust control: During construction erect barriers as necessary to maintain dust in the construction area. Any equipment not relocated cover for dust protection.

● Equipment Room:

● The equipment room is to remain operational through the duration of this project. The equipment room is cooled via two computer room air conditioning (CRAC) units. One of the units is in the path of the replacement but the other unit is to remain operational.

● Temporary Wall - To allow the equipment room to remain operational and protect the operating equipment, a temporary wall will need to be built to subdivide the equipment room into an “operational” side (where existing equipment will continue to run) and a “project” side (where the drain replacement work will occur).

o The Contractor shall provide all labor, materials, tools, equipment, and supervision necessary to complete the installation of the temporary wall.

o Pre-Construction & Prep

▪ Measure and mark the exact centerline of the temporary wall as agreed upon with the NWS.

▪ Protect existing flooring, walls, and furniture in the work zone using drop cloths, plastic sheeting, and masking tape.

o Framing & Installation

▪ Framing: Build a light-gauge metal stud frame spaced 16 inches on center.

▪ Surface Protection (Damage Prevention): Use sill sealer, foam tape, or a non-adhesive barrier between the temporary wall plates (top, bottom, and sides) and the existing finishes to prevent permanent damage.

▪ Anchoring: Secure the wall using non-destructive methods where possible (e.g., tension fitting, or minimal screw attachments into existing studs/joists that can be easily patched later). No heavy anchors shall be driven into floors.

▪ Drywall: Install ½ inch drywall on the “operational” side of the frame.

o HVAC Condensation Lines

▪ CRAC #2 will remain operational through the duration of the project. The condensate from the drain line from CRAC #2 and AHU #1-3 will need to be temporarily re-routed during the project and re-connected at the conclusion of the project.

o Removal

▪ At the conclusion of the project, the temporary wall will be completely removed and the equipment room is to be restored to its original state.

Equipment Room

● On the “Project” side, remove access flooring as necessary for replacement. Disconnect and relocate any wiring, cabling, conduits and electrical determined to be in the path of the replacement. Remove any HVAC equipment determined to be within the path of replacement. The equipment room has one (1) 10-ton computer room air conditioner in the path of the new line. Relocate any server cabinets determined to be in the path of replacement. The equipment room has one server cabinet in the path of the new line. NWS will identify cabling locations for disconnection and reinstallation. (Reference photos provided)

● Raised access flooring will be reinstalled upon completion of the drain line replacement.

Wiring, cabling, conduits and electrical shall be reconnected to their original location unless otherwise determined by NWS. NWS will make the connection to the servers in the equipment room. Coordinate timing with site POC. Cabinets will be reinstalled in their original location unless otherwise determined by NWS. HVAC equipment will be returned to its original location.

● Replace connection from operations drain line into new sewer line.

Equipment Room- (Drain line path under equipment)

● Exterior Main Line – The exterior main line runs approximately 50 ft from the building.
