A. INTRODUCTION/OBJECTIVE

1. The purpose of this project is to install an underfloor electrical gutter system within the Western Area Power Administration (WAPA) Data Center to support the deployment of the new Supervisory Control and Data Acquisition (SCADA) system. The gutter system will provide a dedicated, organized, and protected pathway beneath the raised floor for routing power conductors and associated electrical infrastructure required for SCADA equipment operation.

The objective is to furnish and install a code-compliant underfloor gutter system capable of distributing both 120 VAC and 240 VAC branch circuits from designated electrical panels to strategically located receptacles serving the new SCADA equipment racks, workstations, and supporting devices.

2. To ensure the best results the contractor shall at a minimum, conduct one on-site visit to WAPA’s DSW Phoenix facility prior to commencement of any work. It is the contractor’s responsibility to have a complete technical and visual understanding of the project requirements. The Contractor must also complete all other appropriate pre-construction activities such as, ensuring the proposed activity conforms to all applicable building codes, taking all appropriate measurements, making all appropriate sketches of the proposed project and site layout/conditions; and taking notice of all relevant requirements/considerations. If required, the Contractor may request additional information from the COR/PM.

3. The Contractor is to contact DSW federal employee Timothy Hurst (COR) at 602-605-2726 or hurst@wapa.gov and including Michael Burgess burges@wapa.gov as back up COR designated duties are to verify that the site is ready for the performance of work as set forth in this SOW, to coordinate arrival time to allow a WAPA representative to meet and escort the contractor while on DSW property. The contractor is not permitted to work on-site without the presence of a WAPA representative. Work must be performed Monday through Friday between the hours of 7:00am – 3:00pm. Excluding all Federal Holidays. Work performed outside of these hours must be coordinated and approved 48 hours in advance by the COR.

B. REQUIREMENTS

Installation of Dedicated 120VAC and 240VAC Receptacles for Data Center Re-cabling Project

1. Purpose

The Contractor shall provide all labor, materials, equipment, supervision, testing, permits (if required), and documentation necessary to install dedicated electrical receptacles and circuits within the WAPA Data Center.

2. General Information

· Location: Datacenter

· Electrical Panel: COL-B COL-A

· Approximate distance: See Exhibit A

· Gutter Construction: 16 Gauge steel covers and body

· Gutter features: Open top assembly, removable hinge covers, with knock outs.

3. Scope of Work The contractor shall provide all labor and materials necessary to complete the following work:

A. 240VAC Receptacles Furnish and install a total of eight (8) 240VAC, 20-amp receptacles utilizing NEMA L6-20R locking-type connectors.

Each receptacle shall be supplied by an individual dedicated 20-amp circuit breaker.

No receptacle shall share a circuit with another receptacle.

Circuits shall be distributed between independent A-side and B-side power sources to provide redundant power feeds.

B. 120VAC Receptacles Furnish and install a total of eight (8) 120VAC, 20-amp receptacles utilizing NEMA 5-20R receptacles.

Each receptacle shall be supplied by an individual dedicated 20-amp circuit breaker.

No receptacle shall share a circuit with another receptacle.

Circuits shall be distributed between independent A-side and B-side power sources to provide redundant power feeds.

4. Cabinet Power Configuration Each designated data center cabinet shall receive redundant electrical service as follows:

One (1) 240VAC NEMA L6-20R receptacle connected to the A-side power source.

One (1) 240VAC NEMA L6-20R receptacle connected to the B-side power source.

One (1) 120VAC NEMA 5-20R receptacle connected to the A-side power source.

One (1) 120VAC NEMA 5-20R receptacle connected to the B-side power source.

This configuration shall be repeated for all designated cabinets identified by WAPA as part of the Data Center Re-cabling Project.

5. Installation Requirements The Contractor shall:

Perform all work in accordance with the latest edition of the National Electrical Code (NEC) and all applicable federal, state, and local requirements.

Furnish and install an approved electrical gutter/raceway system beneath the raised data center subfloor for routing all conductors associated with the new 120VAC and 240VAC receptacles. The gutter system shall provide a protected and organized pathway for running the appropriate branch-circuit wiring from the electrical panels to each designated receptacle location. The Contractor shall size all conductors in accordance with the National Electrical Code (NEC), install dedicated wiring for each circuit. A-side and B-side circuits shall be routed separately within the underfloor distribution system whenever practical to maintain power redundancy and minimize the potential for a single point of failure. All wiring shall be properly supported, identified, labeled, and installed in a neat and professional manner that maintains data center airflow, allows future maintenance and expansion, and does not interfere with existing SCADA, communications, network, or facility infrastructure. Upon completion, the Contractor shall ensure all receptacles are operational, properly connected to their respective dedicated breakers, and clearly identified by cabinet designation and power source (A-side or B-side).

6. Testing and Commissioning Upon completion, the Contractor shall:

Verify voltage, grounding, polarity, and circuit continuity.

Test each receptacle for proper operation.

Confirm proper assignment of A-side and B-side power sources.

Update panel schedules to reflect new circuit installations.

Provide testing documentation to WAPA.

C. DELIVERABLES

The Contractor shall provide:

Complete installation of all specified receptacles and dedicated circuits.

Updated panel schedules.

Circuit and receptacle labeling.

Electrical testing and commissioning results.

As-built documentation reflecting final installation, if requested by WAPA.
