1.1 PURPOSE

This manual is intended as a guide for electrical engineers and designers (hereafter referred as the A/E) for the planning and design of the electrical power distribution and related systems (hereinafter referred to as systems) at Department of Veterans Affairs (VA) facilities which are designed and constructed with VA construction budget, as well as owned, operated and maintained by VA.

VA requires the A/E to read, understand, and use this manual in the planning and design of the systems in VA owned construction projects – major, minor and non-recurring-maintenance

(NRM).

In order to provide the latitude needed to incorporate new technologies and concepts, or to accommodate adverse existing construction conditions, technical deviations from the stipulations of this manual may be made. Deviation request(s) may be made only if a safe, reliable, and energy-efficient design shall result. Such deviation request(s) must be approved by VA’s Contracting Officer (CO) and Authority Having Jurisdiction (AHJ). The A/E shall submit deviation request(s) in writing to CO and AHJ, through VA’s Project Manager (PM) and Contracting Officer Representative (COR). Veterans Health Administration (VHA) may require specific web-based procedure for this action; therefore, the A/E shall confirm specific procedure to submit deviation request(s) with CO, PM and COR.

At the minimum, request for deviation(s) shall contain the following elements:

• Narrative detailing reasons for the deviations

• Narrative detailing the design and technical information relating to the deviations

• Statement affirming that deviations shall comply with all public laws, federal regulations, executive orders, and latest applicable codes

• Design drawings of the deviations (if applicable)

• Engineering calculations (if applicable)

• Estimate of cost impact caused by the deviations

• Estimate of schedule impact caused by the deviations

• Supporting documents such as existing site survey photographs, drawings and documents (if applicable)

Deviation request(s) shall be considered approved only after the A/E has received the written approval with signature from CO and AHJ.

1.2 RESPONSIBILITY

The A/E shall provide all necessary professional services to perform planning and design of the systems for the project. The A/E shall be responsible and liable for the professional design in accordance with the contract, safe and practical engineering practices, applicable VA design

General Requirements 1-6 criteria, VA project-specific requirements (if any), and latest applicable codes. The A/E shall be responsible and liable for the content of the construction contract document.

1.3 AUTHORITY HAVING JURISDICTION

The Authority Having Jurisdiction (AHJ) for VHA is the Deputy Undersecretary for Operations and Management (DUSHOM), or his/her designee. Due to the nature of change in personnel and contact information in VA, AHJ and his/her contact information may not be constant.

Therefore, the A/E shall obtain AHJ’s name and contact information from CO, PM or COR.

1.4 COORDINATION

(a) The A/E shall coordinate planning and design work with all disciplines such as architectural, structural, civil, site utility & site work, telecommunications / data, HVAC, plumbing, medical air, fire protection / alarm system, and LEED/Sustainable designs, as applicable.

The A/E shall carefully focus on concealed and underground construction areas, and site utility coordination. The A/E shall coordinate and provide electrical design for all electrically operated equipment shown on other disciplines’ drawings. For example, the A/E shall provide adjustable frequency drives for motors as required on the mechanical drawings;

provide branch circuit power to terminal units, terminal unit fans, smoke dampers, control panels and other auxiliaries; and provide branch circuit power to medical gas alarm panels.

(b) Utility Coordination:

(1) For projects requiring new electrical service, the A/E shall coordinate requirements with the local utility service company. The Contractor’s scope of work, as it relates to the service, shall be detailed in the Construction Documents. The A/E shall forward copies of all correspondence and minutes of meetings with the utility company's representatives to CO, PM and COR regarding negotiations for new services or making changes to the existing services.

(2) For renovations of and/or additions to existing buildings, the A/E shall investigate and confirm the existing electrical service/distribution system. The A/E shall determine whether existing electrical power capacity is available to accommodate new loads. If applicable, the A/E shall inform the electric utility company of the new service requirements and additional loads.

(3) The A/E shall show on civil utility drawings, for coordination purposes, all -major site electrical power distribution components, such as medium voltage and low voltage electrical power feeders, ductbanks, and manholes.

(c) Pre-Design Site Survey: For renovation projects, the A/E shall perform the following tasks:

(1) Electrical Load Monitoring: Investigate the existing electrical service/distribution system and determine whether existing electrical power capacity is available to accommodate the new loads. Determining of existing loads shall be as required by the NFPA 70 - National Electrical Code (NEC).

General Requirements 1-7

(2) Existing Electrical Installation: Investigate and record all existing field electrical installations such as existing underground ductbanks, manholes, concealed conduit runs, conduit types/sizes, cable types/sizes, panelboard types/sizes, electrical equipment locations, etc., which potentially impact the new installation.

1.5 VA DESIGN CRITERIA

1.5.16 VA HOSPITAL BUILDING SYSTEM

The VA Hospital Building System (VAHBS) is a methodology based on a modular concept for planning, designing, and constructing hospitals.

The methodology has been used nationwide with success in capital and operating cost containment, shortened delivery schedules, and improved space utilization flexibility. All new and replacement VA hospital buildings should use the VAHBS system. Also consider using this system for major additions to existing hospitals where future adaptability is an important factor.

The A/E will find that systems schematic/design development efforts will occur much earlier in the overall planning/design process, due to the modular concept. Equipment selection and main distribution sizing should be evaluated as soon as the size and number of modules is determined.

See VHA Program Guide PG-18-3, Design and Construction Procedures, Topic 3, VA Hospital Building System for further guidance.

General Requirements 1-12

1.5.17 COMPUTER AIDED FACILITIES MANAGEMENT REQUIREMENTS (CAFM)

VA intends to implement Computer Aided Facility Management (CAFM) systems in all new and replacement hospital construction, and in all existing hospitals, as feasible. The CAFM concept requires that all pertinent data regarding a facility be contained in a master digital database, accessible by facilities personnel at their workstations for use in operations, energy/cost management, and maintenance, and for planning modifications in facility infrastructure due to space utilization changes.
