SCOPE OF WORK

FOR

TUMR192102 Base Electrical System Study

1.0 GENERAL SCOPE:

The Architect-Engineer shall provide all materials and services for Base Electrical System

Study

2.0 PROJECT DESCRIPTION:

2.1 Muniz Air National Guard Base Power Electrical Distribution system consist of a main underground three phase 4,160V electrical feeder coming from Puerto Rico Electrical

Power Authority (PREPA) existing switch unit 24 (SU-24).This feeder provide power to a main switch unit located next to building 11. Electrical system metering equipment is located in this switch. From the main switch seven underground 4,160V electrical feeders conform the backbone of the base primary distribution system.

2.2 Perform an electrical system study to the Power distribution system of Muniz Air

National Guard Base, Carolina, Puerto Rico. The evaluation should consider the health of the facility’s electrical power distribution system. With the results of the evaluation, provide documentation of existing electrical system configuration, overall system condition, improvement needs and electrical system availability and reliability.

3.0 OBJECTIVES AND MILESTONES:

3.1 Perform an electrical load study (Voltages, VA, Watts, Power factors currents etc.) and power quality assessment throughout the installation of power recorders and or harmonic analyzer at the main switch unit (4.16kV) and to all the distribution transformers.

3.2 Perform visual inspection as necessary to the Base Main electrical distribution system, including main switch unit, substation A and B, distribution transformers, underground primary feeders, electrical manholes etc.

3.3 Contractor is responsible of provide manpower and materials to open manholes and provide dewatering system if necessary to perform the electrical manholes inspections.

3.4 The contractor shall provide all labor, equipment, supplies, consultant services and all site investigations, surveys, analysis and verification of existing electrical system in order to complete this study.

3.5 Attend a preliminary conference to discuss the requirements and walk through of the area. Gather required information to begin the assessment.

3.6 Contractor Qualifications: The study shall be prepared by a qualified Registered

Professional Electrical Engineer licensed in Puerto Rico working for an Electrical

Testing Company (NETA Full member Company) with a least 10 years of experience performing this type of studies and analysis.

3. Descriptions of the scenarios evaluated and the basis of each.

4. Tabulations of power, RMS current, RMS Voltage, Peak Voltage, power factor versus equipment ratings. The tabulation shall identify percentage of rated load and the scenario for the percentage is based. Overloaded equipment shall be clearly noted.

5. Tabulations of calculated voltage distortion factors, current distortion and individual harmonics vs the limits specified by ANSI/IEEE519.

6. Comparison equipment nameplate data with available drawings and specifications.

7. Inspection of physical and mechanical conditions.

8. Inspection of anchorage, alignment, grounding, and required area clearances.

9. Conclusions,recommendations and recommendations estimated cost.

4.03 The 100% Final report specifications shall be submitted using Word for Windows version 6.0. In addition a PDF copy of the final report will be required. The report shall be placed on compact disks. All report shall be typed on 8 1/2" X 11" pages
