To build a retaining wall that could hold a 100-foot by50-foot reinforced concrete pad on a 2:1 slope, the US Army Corps of Engineers relied on Kapur to serve as the design-build team’s design quality manager.
The retaining wall also needed to be 10 feet higher than the dam and have explosive sight approval, as it necessitated the capability of handling 80,000 pounds worth of live loads, not to mention the equipment to move it.
Kapur staff wrote the proposal and price for the design side of the project, developed the work breakdown, formed the multi-discipline design team, and maintained continuity throughout the entire design process.
Also included were the design of:
- A 750 KVA, 120/208 Volt, three-phase, four-wire pad-mounted transformer near the existing overhead power lines along the road with terminations at the pole, underground primary feed to the transformer, grounding, and metering.
- A 2,000 Amp, 208V, three-phase, four-wire power distribution panel in a weatherproof enclosure, which required grounding, amount on the north retaining wall, the distribution panel to contain the main circuit breaker, two 900 Amp, one pole circuit breaker for each of the three conex box housing test equipment and the necessary 20 Amp, and one pole circuit breaker to feed the enclosure.
- Six 20 Amp, 120V, duplex receptacles mounted in a weatherproof enclosure on the north retaining wall while providing the necessary circuit breakers and feeds to the distribution panel.
- An underground feeder cable from the pad-mounted transformer to the power distribution panel on the north retaining wall with disconnect switches for future equipment hookups.
