About this file
This is an electrical site plan document for the State of Hawaii's boat lift improvements project at Pier 1 in Hilo Harbor (Project P50217). The plans detail the installation of electrical infrastructure to support a new pre-engineered elevator boat lift structure, including partial electrical site plans, enlarged electrical details, equipment specifications, and duct encasement requirements. The project encompasses trenching for electrical conduits, installation of electrical connections for the boat lift system, and coordination with existing electrical panels and transformer equipment. Key electrical components specified include a 3-phase 200-amp equipment enclosure, a 15KVA dry-type transformer rated 240X480V to 120/240V, disconnect switches rated at 2-pole 30-amp and 2-pole 20-amp, and multiple junction boxes constructed from 6-inch square by 4-inch deep and 12-inch square by 6-inch deep NEMA 4X 316 stainless steel enclosures. The plans establish detailed duct and wire schedules for various utility lines, including primary/secondary electric, control/instrumentation, and telecommunications conduits, with specific minimum separation requirements and concrete encasement specifications. Equipment racks are designed using 1-5/8 inch 316 stainless steel C-channels and brackets, fabricated to nominal 24 by 36-inch dimensions and adjustable based on final requirements.
The estimated construction cost for the overall boat lift improvements project ranges from $350,000 to $450,000. Each boat lift track will be mounted on a concrete pile cap supported by micropiles below, with restoration of asphalt concrete pavement, chain link fencing, gates, and miscellaneous site elements included in the scope. The electrical plans were certified by Adobe Acrobat Sign on April 16, 2026, indicating these are final construction documents ready for bidding and implementation.
