4-26-0047-5 Bid Sheet.xlsx

This is a bid sheet for the Colonel Estill Drainage Improvements project in unincorporated Chatham County, Georgia, on Isle of Hope along Colonel Estill Avenue. The project scope encompasses removal of existing drainage pipes and structures, installation of new stormwater pipes and structures ranging from 18-inch to 24-inch storm drain pipe and 24-inch by 38-inch elliptical concrete pipe, construction or modification of open channels, utility adjustments, and associated infrastructure work. Major bid line items include mobilization, site clearing and grading, unsuitable subgrade material removal (150 cubic yards), foreign borrow material (200 cubic yards), installation of grate inlets (3 units), traffic control, utility coordination including water meter relocation (8 units) and water service line adjustments (8 units), pavement and concrete work totaling 210 square yards of removal and replacement, riprap installation, erosion and sedimentation control measures including silt fence and floating sediment barriers, and permanent grassing with sod (3,600 square yards).

The bid sheet includes 28 line items with quantities and unit prices, all priced at $0.00 except for a Field Condition Allowance of $50,000.00, resulting in a total project cost of $50,000.00. This allowance structure suggests the bid sheet is a template awaiting contractor pricing, or the Field Condition Allowance represents a contingency for unforeseen site conditions. The project requires maintenance of traffic flow and property access throughout construction, with temporary stormwater blockages permissible. Erosion and sedimentation control plans must be implemented prior to construction and maintained throughout the project duration, with coordination required with utility providers to manage impacts to water service infrastructure.
