This is a comprehensive set of design and construction drawings for cable replacement at Houma-Terrebonne Airport in Houma, Louisiana. The project involves replacing high-voltage buried power cables serving runway 18 at the facility.

The drawings include detailed site plans, electrical schematics, and construction specifications for a complete cable replacement system. Key components include: new underground power conduits with 4-inch PVC duct banks; a 15 kVA step-down transformer and distribution panel assembly; medium intensity approach lighting system (MALS) and runway alignment indicator lights (RAIL); threshold lights with low-impact resistant structures mounted up to 40 feet; semi-flush light fixtures and frangible light bars; power and control stations with complete electrical wiring diagrams; grounding systems with exothermic welds and copper connections; and associated junction boxes, cable racks, and mounting hardware. The specifications call for 600-volt and 2,400-volt power service cables, with 120/240-volt feeders for lighting circuits. All underground cables require 10-foot easement depth, and the design includes detailed drainage, foundation, and anchoring provisions for towers and light fixtures. The warning signage for high-voltage buried cable indicates contact numbers 985-879-4309 or 1-800-272-3020 before digging. Construction standards reference FAA specifications, NEMA standards, and ASTM requirements for materials and installation practices.
