This is a construction plan document prepared by MG Engineering Associates, LLC for the Borough of Colwyn, Delaware County, Pennsylvania, detailing the Floyd Park Stormwater Basin Improvements project funded by DCED and DELCO Greenways Grants. The project scope encompasses site clearing and earthwork, soil erosion and sediment control measures, drainage infrastructure installation, rain garden construction, retaining wall and fencing installation, and final site restoration at the intersection of S. 5th Street and Ellis Avenue. The bid item list includes 16 line items with quantities ranging from 1 lump sum for mobilization to 635 linear feet of perforated underdrain, 260 linear feet of reinforced concrete pipe (RCP) in both 36-inch and 48-inch diameters, 245 square yards of bio-soil planting mix, 405 linear feet of retaining wall with chain-link fence, 350 linear feet of 6-foot chain-link fencing, and various riprap aprons and site improvements. Sealed bids were to be received online via PennBid by April 7, 2026, at 4:00 p.m. prevailing time, with no physical public bid opening scheduled. The project is located within the 100-year floodway and includes approximately 25,000 square feet (0.574 acres) of earth disturbance requiring comprehensive erosion and sediment control measures.

Bidders are required to submit a surety bond or equivalent meeting 10 percent of the overall bid price, with additional payment and performance bonds of 100 percent of the contract amount due within ten calendar days of acceptance and a 12-month maintenance bond at 15 percent of improvement costs. The successful bidder will be assessed a PennBid transaction fee of 0.0033 percent (up to $6,000) of the contract award value. The project is subject to Pennsylvania Prevailing Wage Requirements as detailed in the contract documents. All contractor responsibilities are clearly delineated, including site familiarization, utility coordination and location via PA One Call system, coordination with electrical service providers, permit acquisition, trench maintenance, OSHA compliance, and removal of existing utilities and hazardous materials prior to demolition. The contract documents specify that contractors must hire a Pennsylvania-licensed land surveyor for staking and surveying, provide shop drawings and submittals for review prior to installation, and submit curb stakeout, structure stakeout, and compaction reports verified by a qualified soils engineer. The Borough of Colwyn reserves the right to reject any or all bids.
