Piedmont Convenience Center Upgrades - Design Drawings Summary
This is a set of architectural and engineering design drawings prepared by HDR Engineering Inc. for Greenville County, South Carolina, for the Piedmont Convenience Center located at 225 Owens Road, Piedmont. The project involves installing concrete pads for two waste compactor units and two charge boxes, along with associated site infrastructure improvements. The scope of work includes asphalt cutting and removal, concrete pad installation, trenching for electrical conduit and drainage piping, electrical panel and equipment rack installation, drainage structure construction, and stormwater management. The drawings, dated April 2026 and marked "Issued for Proposals," provide detailed site plans, existing conditions documentation, and construction specifications. The construction schedule outlines eight sequential phases: utility location and confirmation, site layout staking, traffic control installation, pavement removal, trench drain and conduit installation, drainage structure installation, concrete pad placement, electrical equipment installation, and electrical connections to the existing 480V 200A panel. The project engineer is P. Westmoreland, P.E., and topographic survey data was performed by Freeland & Associates Inc. on March 26, 2026.
The technical specifications detail multiple concrete pads with varying dimensions—equipment pads measuring 10 feet by 17 feet and container pads measuring 10 feet by 25 feet—constructed to 3,000 PSI compressive strength using ready-mix concrete per ASTM C94 standards. Electrical requirements include installation of a proposed 480V 200A sub-panel with 3R disconnect switches for 20 horsepower compactors and control wiring specifications. Drainage infrastructure consists of 6-inch PVC drainage pipes, trench drains (8 inches wide, 8 feet long, 5 inches deep), sump drainage details, and precast drainage structures to be provided by the owner. The drawings specify the use of stainless steel equipment racks with corrosion-resistant materials and detailed connection methods including PVC-coated rigid galvanized steel conduit, flexible boots for pipe connections, and specialized sealants such as Sikaflex-410 asphalt sealant. The project indicates that the convenience center will remain open to the public during construction, with brief closures to be coordinated with the County in advance.
