2.13 PAVEMENT

2.13.1 After placement of the vehicle barrier, the pavement sections shall be replaced to match the section and depth of the surrounding pavement. Pavement shall be warped to match the elevations of existing pavement. Positive surface drainage, away from the vehicle barrier, shall be provided by pavement slope.

PART 3 EXECUTION

3.1 INSTALLATION

3.1.1 Installation shall be in accordance with manufacturers instructions and in the presence of a representative of the manufacturer. Manufacturer's representative shall be experienced in the installation, adjustment, and operation of the equipment provided. The representative shall also be present during adjustment and testing of the equipment.

3.2 HYDRAULIC LINES

3.3 PIT DRAINAGE

3.3.1 Federal and/or state EPA regulations may require that an oil/water separator be installed in the pit drainage system to ensure capture of any hydraulic fluid that may leak out of the system. If pit/vault type construction is required provisions shall be made for drainage and connection to storm drainage system, or if no storm drain exists, a self-priming submersible sump pump of adequate capacity shall be specified. A drain connection and oil/water separator shall be provided in each barrier that requires pit/vault type construction. Hookups between the storm drains shall be made as specified on plans.

3.4 ELECTRICAL

3.4.1 All control power wiring requiring compression terminals shall use ring-style terminals.

Connections between any printed circuit cards and the chassis shall be made with screw connections or other locking means to prevent shock or vibration separation of the card from its chassis. The electrical power supply breaker for the hydraulic power unit shall be capable of being locked in the power on and power off positions.

3.5 FIELD TESTING

3.5.1 Upon completion of construction, a field test shall be performed for each vehicle barrier. The test shall include raising and lowering the barrier, both electrically and manually, through its complete range of operation. Each vehicle barrier shall then be continuously cycled for not less than 30 minutes to test for heat build-up in the hydraulic system. The Contracting Officer shall be notified at least 7 days prior to the beginning of the field test. The Contractor shall furnish all equipment and make all necessary corrections and adjustments prior to tests witnessed by the
