About this file

The document is a preliminary conceptual site plan for a 911 Emergency On-Call Center project in Clarendon County, South Carolina, prepared by Alliance Consulting Engineers, Inc. The plan covers a ±10-acre parcel and includes a proposed ±11,430-square-foot Community Family Resource Center building. The site plan details include a proposed stormwater basin, existing wetlands, parking areas (32 total parking spaces with 1 ADA spot per 25 spaces), and various site improvements such as sidewalks, asphalt paving, and a stop sign with stop bar.

The site plan includes detailed quantity take-offs for various construction elements, with estimated quantities for mobilization, silt fence (700 linear feet), clearing and grubbing (approximately 1 acre), earthwork (approximately 2,000 cubic yards), and paving materials. Additional site preparations include erosion and sediment control measures, outlet control structures, striping and signage, and grassing. The document also outlines preliminary engineering and design costs, including topographic survey (approximately $15,000), geotechnical exploration (approximately $10,000), and engineering design and permitting (8% of subtotal), with provisions for construction administration and materials testing.

Rip Rap Outlet Protection: Assumed One (1) Basin Outfall: 1 EA X (10 CY / EA) = ~ 10-CY

Striping and Signage:

Parking Striping: 9 Spaces X 18-LF = 162-LF = ~ 200-LF

Stop bars and signage: 1 EA X (12-LF / EA) = 12-LF;

Total: 200-LF X ($1.50 / LF 4-inch Stripe) + 12-LF X ($10 / LF Stop Bar) + 1 EA X ($500 / EA)

Grassing: 0.33-Acre (From CAD) = ~

1 Acre

Topographic Survey: $12,200 (Nesbitt) X 1.15 = $14,030 = ~ $15,00

Geotechnical Subsurface Exploration: $8,000 (ECS) X 1.15 = $9,200 = ~ $10,000

Engineering Design and Permitting: 8% of Subtotal

Construction Administration and Observation: 6% of Subtotal

Construction Materials Testing: 3% of Subtotal
