| | | | | | | | BACKGROUND
The Allenwood Drainage Basin has been developing over the years to the point that improvements to the existing detention pond (currently owned by the Allen Economic Development Corporation) are needed.
In March 2019, the entire project was initially put out for bid and prices came in over-budget. To reduce the cost of the overall project, staff chose to deliver the project through multiple construction contracts (separated by specialty / trade). The waterline lowering has been completed and this next contract / phase will primarily involve excavating the detention pond lower, reconstructing the culvert under the DART Railroad, and stabilizing the channel banks downstream. This approach yielded a savings of $685,000 as compared to the original bid.
When complete, this project will accommodate a fully developed basin, replace a structurally deficient culvert, and address hydraulic concerns of neighboring property owners.
On January 9, 2020, six (6) bids were received. The three (3) lowest and responsive bids are below:
