4.1 General Requirements.

4.1.1. General Requirements. The Contractor shall visit the site to verify all electrical site conditions and shall consider all existing site conditions in all proposal, design, and construction efforts. The Contractor shall become familiar with all electrical requirements of this project prior to bidding. The Contractor shall demolish and remove off-base all existing materials and objects which conflict with the new/repaired construction; and shall provide all labor and materials and equipment to provide a new/repaired facility.

4.1.2. General Scope. The Contractor shall design and provide replacement systems for all electrical systems and utilities, including but not limited to telephone/data, for this project. The Contractor shall coordinate with the local CATV company, local telephone company, and the Davis-Monthan AFB electric shop to demolish and remove the existing overhead CATV, street lighting, telephone/communication, and existing related power-apparatus equipment, and devices, etc., in this project site; and install new OH, CATV, power, telephone/communication, as required in this

RFP.

4.1.3. Commercial Codes and Design Manuals. All design and installation work shall conform to the latest editions of the references listed in Section 2.13.8, unless otherwise indicated herein.

4.1.4. NEC Covered vs. Non-Covered. All electrical systems and equipment, both interior and exterior, installed under this project shall, for the purposes of NEC application and compliance, be considered as "Covered" and shall be installed per the requirements given in the NEC. None of the systems or equipment installed shall be considered as "electric utility" systems or equipment. However, the power cables going from the exterior transformers to the buildings shall be considered as the "service" or as "service conductors" and shall be installed per the requirements given below and in accordance with NEC applicable articles.

4.1.5. Coordination. Electrical work shall be coordinated through the Contracting Officer. The order of construction shall be as directed under "phasing", in other parts of this RFP.

4.1.6. Digging Permits. Digging permits shall be obtained in accordance with the procedures outlined in paragraph 2.2c., Utility Outages, Road Closures, and Digging Permits –“Base Outages and Digging Permits (AF Form 103, BCE Work Clearance Request)” of Section 01010, Summary of Work.

4.1.7. Specifications. Specifications shall be provided as part of the contract documents for this project.
