Crowder Construction Company Civil & Environmental Division, Apex, NC, was awarded the 2005 Carolinas AGC Pinnacle Award for “Best Utility Project" for its work as contractor on Table Rock Intake in Cleveland, SC. The Best Building Project award was presented to Crowder Construction Civil & Environmental Division at the Carolinas AGC Annual Convention at The Ritz-Carlton Grande Lakes in Orlando, FL, January 27, 2006.
Near the Carolinas/Georgia border, Table Rock Lake has been the primary water source for Greenville, SC for 80 years. This project involved 2 new 48-inch screened intakes below the existing ones, in order to provide up to 35 million gallons a day to the area. The construction took place in 55 feet of water in this mountain reservoir.
Fellow utility contractor judges were quite impressed with the ultimate challenge: opening a 105-foot vertical shaft and 500-foot tunnel amid complex underlying geological materials. These openings had to be accurately intersected with pinpoint accuracy. And maintaining the integrity of the earthen dam was critical throughout.
Meanwhile 2 hurricanes drove lake levels above design parameters, and above all Crowder had to maintain the drinking water quality.
In a partnering approach to a public utility project, the team had to create and pave a new road, and engineer a 4-barge system on which cranes would sit. They also had to change casing lengths just to get material to the site via hairpin mountain roads.
Safety planning was paramount, involving the GC, Owner and subs, addressing many unique hazards including redundant plans for emergency egress from the shaft and retrieval of workers.
As a subcontractor put it: safety was #1 for everybody every day. In 36,000 man-hours, the project had zero lost-time injuries, zero environmental damage, and zero schedule slippage.
