Performance Work Statement

Mini-Split System Replacement and Electrical System Upgrade

Overview

Site Location

The Western Oregon Service Unit (WOSU) is in Salem, Oregon, approximately 43 miles south of Portland, Oregon (Attachment A). The project location and physical address are below.

Western Oregon Service Unit

Chemawa Health Center 3750 Chemawa Rd. NE Salem, Oregon 97305

Background

The Pod 2 Server Room is a small interior equipment closet—approximately 64 square feet— with no exterior walls. All heat in the space is generated by the equipment itself; envelope heat gain is minimal compared to equipment load.

The room is undergoing an IT equipment upgrade as part of the IHS Cisco Refresh Project.

Incoming network switches are larger and draw significantly more power than the units they replace, which has two direct consequences for the building infrastructure:

1. The existing electrical system does not provide the quantity or type of circuits required by the new equipment. Sixteen (16) dedicated 208/240V, 20-amp circuits with NEMA L6- 20R twist-lock receptacles are required to serve the new switch power connections. The building’s primary distribution is 480V; existing 208/240V panel capacity in the vicinity of the server room shall be evaluated before assuming new step-down infrastructure is required.

2. The existing 1-ton Daikin mini-split (model RK12NMVJU) has proven inadequate for the current equipment load, resulting in recurring overheating events. The incoming equipment will substantially increase the room's heat load. The estimated design load following the upgrade is approximately 36,000 BTU/hr (3 tons), requiring an appropriately sized replacement to meet that demand.

The IT equipment upgrade itself, network switch installation, cabling, and configuration, is being performed separately by IHS IT staff and is not part of this contract.

Objective

The objective of this project is to provide a fully operational electrical and HVAC infrastructure in the Pod 2 Server Room capable of reliably supporting the upgraded IT equipment without overheating, in compliance with all applicable codes and standards. The Contractor's scope is limited to the electrical and mechanical work described in this PWS.

C. Equipment/Material Specifications

Electrical

Sixteen (16) dedicated branch circuits, each rated at 20 amperes, 208/240V (or equivalent as required to serve equipment and confirmed by field conditions), with NEMA L6-20R twist-lock receptacles, are required in the server room. Each circuit shall be served by an individual 2-pole breaker. No sharing of circuits between power supply connections is acceptable.

Branch circuits shall be distributed across panel phases and sections to maintain equipment resiliency consistent with manufacturer redundancy requirements. The intent is to ensure that no single breaker, phase, or panel section failure results in the loss of all power supply connections to a single switch chassis.

The Contractor shall evaluate existing electrical infrastructure in the vicinity of the server room to determine the most appropriate and cost-effective power source for the new branch circuits. If the existing 208/240V panel capacity is available and sufficient, it shall be used. If no suitable source exists, all required upstream infrastructure shall be provided, which may include a 480V feeder breaker, step-down transformer, and new three-phase subpanel. Upstream equipment shall be sized to the estimated coincident room demand of approximately 10,000 watts, with appropriate NEC demand factors, load diversity, and future capacity margin. The arithmetic sum of branch circuit breaker ratings shall not be used as the basis for feeder or transformer sizing.

A complete, labeled panel schedule shall be provided, and the circuit directory updated to reflect all new circuits, receptacle locations, and equipment served.

HVAC

A new approximately 36,000 BTU/hr (3-ton) mini-split heat pump system, capable of maintaining a stable server room temperature under full equipment load, is required. The system shall be Daikin or an approved equal, with a minimum efficiency rating of 17

SEER.

The system shall be variable-capacity (inverter-driven). Fixed-speed or single-stage systems are not acceptable; the small, enclosed room environment makes stable temperature control without short cycling a critical performance requirement. The system shall be capable of stable operation at low sensible loads without hunting or short cycling.

At least one (1) wall-mounted interior head shall be installed within the server room, positioned to provide effective airflow distribution across equipment racks. The Contractor shall propose the number and placement of interior heads appropriate to the room size and configuration, subject to COR approval. Placement shall be shown on shop drawings prior to installation.

The interior head(s) shall be equipped with condensate pump(s). Condensate shall be routed to an approved discharge location in a manner that eliminates any risk of dripping or leaking over server racks, electrical equipment, or active cabling.

The system shall include a wall control or thermostat with a digital display and manual temperature setpoint capability.

As-equal products will be evaluated based on the following salient characteristics:

• Rated cooling capacity of approximately 36,000 BTU/hr

• Variable-capacity / inverter-driven compressor

• Minimum 17 SEER efficiency rating

• UL Listed

• Wall-mounted interior head(s) suitable for server room installation

Equipment Load Table

The following table represents the design-basis heat load for the Pod 2 Server Room following the equipment upgrade. Because the room is an interior space with no exterior walls, envelope heat gain is minimal compared to equipment load, and the design load is driven entirely by equipment heat dissipation. Values marked "Estimated" reflect engineering judgment based on measured Command Line Interface (CLI) data from the existing switches and published Cisco platform specifications; field verification is required during the load calculation phase.

Equipment Qty Unit Load

(W) Total Load

(W) Basis

Cisco Catalyst 9410R Switches 2 ~3,000-

3,500 ~6,000- 7,000

Estimated - scaled from measured chassis internal power dissipation (excluding PoE) on existing Catalyst 4500 VSS pair ~1,196W internal on active chassis, adjusted for 8-blade vs. 5-blade configuration with margin

Tripp Lite UPS

(SU3000LCD2UHV) 1 1,600 1,600

Confirmed—LCD display reading under operational load

ScriptPro System (existing, no change) 1 ~500 ~500

Estimated: existing 110V circuit; no modifications to this system

C9300 Switch (replacing 2960-X) 1 ~200 ~200

Estimated; served from existing UPS; no new circuit required

Miscellaneous / Allowance ~500

Allowance for lighting, incidentals, and load growth

Design Basis Total ~10,000W

HVAC Design Load 36,000 BTU/hr (3 tons)

Includes safety factor for load growth and estimation uncertainty

Note on PoE Load: The Catalyst 9410R switches supply Power over Ethernet (PoE) to phones, wireless access points, and downstream devices located throughout the facility - not within the server room. Of the 2,205W measured on the active existing chassis, approximately 1,009W was inline PoE load delivered to downstream devices outside the room. Because this power is dissipated outside the server room, it does not contribute to the room's cooling load. Equipment load values in the table above reflect chassis internal power dissipation (excluding PoE delivered to remote devices), consistent with the measured CLI data methodology used to establish the design basis. This is the technical basis for the 3-ton HVAC design load; switch power supply nameplate ratings and Cisco's published maximum BTU figures are not used as the design basis.
