1.3 QUALITY CONTROL

1.3.1 Regulatory Requirements

In each of the publications referred to herein, consider the advisory provisions to be mandatory, as though the word, "shall" had been substituted for "should" wherever it appears. Interpret references in these publications to the "authority having jurisdiction," or words of similar meaning, to mean the Contracting Officer. Ensure equipment, materials, installation, and workmanship are in accordance with the mandatory and advisory provisions of NFPA 70, unless more stringent requirements are specified or indicated.

1.3.2 Standard Products

Provide materials and equipment that are products of manufacturers regularly engaged in the production of such products which are of equal material, design and workmanship. Provide products which have been in satisfactory commercial or industrial use for 2 years prior to bid opening. Ensure the 2-year period includes applications of equipment and materials under similar circumstances and of similar size. Ensure the product has been on sale on the commercial market through advertisements, manufacturers' catalogs, or brochures during the 2-year period. Where two or more items of the same class of equipment are required, these items must be products of a single manufacturer.

1.4 ACCIDENT PREVENTION PLAN (APP)

Submit the Accident Prevention Plan (APP) for review and acceptance by the Government at least 15 calendar days prior to the start, after being given Notice to Proceed. A competent person must prepare the written site-specific APP. Prepare the APP in accordance with the format and requirements of EM 385-1-1, ENG Form 6293, and herein. The APP must be job-specific and address any unusual or unique aspects of the project or activity for which it is written. The APP must interface with the

Contractor's overall safety and occupational health program referenced in the APP in the applicable APP element and made site-specific. Describe the methods to evaluate past safety performance of potential subcontractors in the selection process. Also, describe innovative methods used to ensure and monitor safe work practices of subcontractors. The Government considers the Prime Contractor to be the "controlling employer" for all worksite safety and health of the subcontractors. Contractors are responsible for informing their subcontractors of the safety provisions under the terms of the Contract and the penalties for noncompliance, coordinating the work to prevent one craft from interfering with or creating hazardous working conditions for other crafts, and inspecting subcontractor operations to ensure that accident prevention responsibilities are being carried out. The APP must be signed in accordance with the APP and ENG Form 6293 Accident Prevention Plan Worksheet. The SSHO must provide and maintain the APP and a log of signatures by each subcontractor foreman, attesting that they have read and understand the APP, and make the APP and log available on-site to the Contracting Officer. If English is not the foreman's primary language, the Prime Contractor must provide an interpreter.

Work cannot proceed without an accepted APP. Once reviewed and accepted by the Contracting Officer, the APP and attachments will be enforced as part of the Contract. Disregarding the provisions of this Contract or the accepted APP is cause for stopping of work, at the discretion of the Contracting Officer, until the matter has been rectified. Continuously review and amend the APP, as necessary, throughout the life of the Contract. Changes to the accepted APP must be made with the knowledge and concurrence of the Contracting Officer, project superintendent, SSHO and Quality Control Manager.

Incorporate unusual or high-hazard activities not identified in the original APP as they are discovered.

Should any severe hazard exposure (i.e., imminent danger) become evident, stop work in the area, secure the area, and develop a plan to remove the exposure and control the hazard. Notify the Contracting Officer within 24 hours of discovery. Eliminate and remove the hazard. In the interim, take all necessary action to restore and maintain safe working conditions in order to safeguard onsite personnel, visitors, the public (as defined by ANSI/ASSP A10.34), and the environment.

1.5 CONFINED SPACE ENTERY REQUIREMENTS

Confined space entry must comply with EM 385-1-1, 29 CFR 1926, 29 CFR 1910, and Directive CPL

2.100. Any potential for a hazard in the confined space requires a permit system to be used.

PART 2 PRODUCTS

2.1 MATERIALS

2.1.1 Multiconductor Cable

Provide three conductor, 600-volt, multiconductor cable with 250 kcmil conductors and #4 AWG ground.

Cable shall be tray cable rated with NEC type XHHW-2 insulation complying with UL 44, a continuous, extruded, corrugated aluminum sheath, and an outer PVC jacket. Aluminum sheathed cables shall comply with UL 1569 as NFPA 70, Type MC cable with sunlight resistant jacket suitable for direct burial.

PART 3 EXECUTION

3.1 DEWATERING

Submit dewatering plan for review 14 days prior to the commencement of work.

3.2 CABLE INSPECTION

Inspect each cable reel for correct storage positions, signs of physical damage, and broken end seals prior to installation. If end seal is broken, remove moisture from cable prior to installation in accordance with the cable manufacturer's recommendations.

3.3 INSTALLATION

Install conductors in accordance with the manufacturer's published instructions and with the requirements and recommendations of NFPA 70.

3.3.1 Pull Cord

Install pull cords in conduits when removing abandoned cables. Pull wire: plastic having minimum 890- N 200-pound force tensile strength. Leave minimum 915 mm 36 inches of slack at each end of pull wire.

3.3.2 Conductor Identification

Provide conductor identification at the top and bottom of each vertical shaft and where conductors enter and exit the crossover duct bank. Cable tags must be attached to the cable with stainless steel wire not smaller than 14 AWG so that movement of the tag along the length of the cable is not possible.

3.4 FIELD QUALITY CONTROL

3.4.1 600-Volt Wiring Test

Test wiring rated 600 volt and less to verify that no short circuits or accidental grounds exist. Perform insulation resistance tests using instrument which applies voltage of 1,000 volts DC for 600 volt rated wiring per NETA ATS to provide direct reading of resistance. Each segment of cable must be tested individually prior to splicing the cable. Followed by testing the circuit in its entirety upon completion of installation.

3.4.2 Phase Rotation Test

Perform phase rotation test to ensure proper rotation of service power prior to operation of new or reinstalled equipment using a phase rotation meter. Follow the meter manual directions performing the test.

3.5 CLEANUP

Remove debris, cable, and rubbish from site. Remove and transport the debris in a manner that prevents spillage on streets or adjacent areas. Apply local regulations regarding hauling and disposal.
