REQUIREMENT FOR ELECTRICAL ENGINEERING SERVICES

FOR PROJECT 586-20-106 DESIGN

UPGRADE FACILITY ELECTRICAL DISTRIBUTION

I.GENERAL SCOPE: The Electrical Engineer shall provide all engineering services as defined herein to accomplish complete contract drawings, specifications, technical reports, and cost estimates for the following work:

A. This design evaluates, replaces, and upgrades two existing medium voltage switchgears, medium voltage switchgear/generator controls, and six pad mount transformers. Replace existing with one new combined medium voltage switchgear, new non-proprietary medium voltage switchgear/generator controls, and six new pad mount transformers and an option to replace 14 low-voltage automatic transfer switches and controls. A listing of major items of electrical equipment to be evaluated/replaced is listed below.

a. - Medium Voltage Switchgears.

b. – Medium voltage switchgear and generator control circuitry.

c. - Pad Mount Transformers. All feeds between transformer and switchgear shall be tested. Failed feeds shall be replaced.

d. - Automatic Transfer Switches and controls.

IMPORTANT: It is the engineer-of-record’s responsibility to self-perform extensive and repeated site evaluations to determine and assure the accuracy of provided drawings and the condition of equipment specified for replacement. It is the engineer-of-record’s responsibility to prioritize replacement items such that the equipment in worst condition is replaced first and to develop a project that fits the VA’s anticipated construction budget of $4.0 +/- million.

B. Provide complete arc flash, load flow, and relay coordination studies to include selective coordination of circuit breaker trip settings for all installed equipment and stamped by the engineer-of-record. The load flow study shall be performed throughout design development to inform the new design. The relay coordination study shall be performed using the technical parameters of the ACTUAL equipment the contractor submits and is approved for installation, i.e., during the construction phase.

a. Selective coordination is defined as an electrical system design in which the upstream circuit breaker (fuses are not allowed) nearest to the system fault clears the fault without affecting the protective devices that are upstream from it.

b. A load flow study is defined as a numerical analysis of the steady-state conditions of the entire facility’s electrical system. Its goal is to determine the flow of power, current, voltage, real power, and reactive power in a system under all realistic load conditions, i.e., utility and generator operation.

C. Provide NEC-compliant arc flash labels for all new and existing-to-remain equipment.

D. All transformers shall exceed DOE 2016 transformer specification requirements. Specifications for 2500kVA transformers shall exceed mathematically interpolated DOE 2016 ratings for transformers that are larger than considered by DOE 2016 requirements.

E. All medium voltage cables shall include all copper conductors, concentric wire (not foil) neutrals, and EPR insulation in PVC jacketing.

F. This project will be a one for one replacement. Facility is a 24-hour operation and must remain operational. Design to reflect continuous operation of electrical to facility.
