(4) Para 3.7: Add new sub paragraph 3.7.1.1: "The lighting fixtures will be replaced with complete Killark 150 watt HPS fixtures P/N EZS150A2-T, guard P/N EZG1, Standard Dome Reflector P/N VMPSD-40 and Lamps." (5) Para 3.9: Change to read: "3.9 TESTS 3.9.1 Operating Tests: After the installation is completed, and as such time as the Contracting Officer may direct, the Contractor shall conduct operating tests for approval. The equipment shall be demonstrated to operate in accordance with the specified requirements. 3.9.2 Field Tests: The Contractor shall notify the Contracting Officer at least 2 calendar days prior to conducting field tests. The Contractor shall furnish all materials, labor, and equipment necessary to conduct field tests. The Contractor shall perform all tests and inspections recommended by the manufacturer unless specifically waived by the Contracting Officer.

All field test reports will be signed and dated by the Contractor. 3.9.2.1 Safety: The Contractor shall provide and use safety devices such as rubber gloves, protective barriers, and danger signs to protect and warn personnel in the test vicinity. The Contractor shall replace any devices or equipment which are damaged due to improper test procedures or handling. 3.9.2.2 Cable Tests: The Contractor is responsible for identifying all equipment and devices that could be damaged by application of the test voltage and ensuring that they have been properly disconnected prior to performing insulation resistance testing. An insulation resistance test shall be performed on all low and medium voltage cables after the cables are installed in their final configuration and prior to energization. The test voltage shall be 500V DC applied for one minute between each conductor and ground and between all possible combinations of conductors. The minimum value of resistance shall be: R in megohms = (rated voltage in kV + 1) x 304,800/length of cable in meters. (R in megohms = [rated voltage I kV +1] x 1000/length of cable in feet. Each cable failing this test shall be repaired or replaced. The repaired cable system shall then be re- tested until failures have been eliminated. 2.
