In 2013, the City completed a drainage analysis of the Covington Woods Subdivision and Business Park, as well as surrounding areas. The analysis determined that areas of Covington Woods are subject to roadway inundation during medium to extreme rain events. Some of the roadways are impassible during these events leading to decreased mobility and impaired emergency response. The analysis identified these areas as needing drainage improvement.
On July 17, 2018, City Council awarded a construction contract to Allgood Construction for the Jess Pirtle Side Streets Drainage Improvements Project, CIP DR1701. The scope of the project includes storm drain improvements on Greywood Drive, Sugardale Court and Sugarfield Court, as well as additional alternate for paving on Greywood Drive, extending the limits of the pavement to be replaced at the request of Public Works. Bids were received and the alternate bid items for pavement replacement were awarded by City Council.
Greywood Drive, Sugardale Court and Sugarfield Court are on the Public Works Department's list of streets for replacement based on the City's Pavement Management Program (PMP) scoring system. These areas are adjacent to the work being performed under the current ongoing drainage project. Replacing these areas in the current contract will minimize the negative impact to the residents in the area by allowing for one contractor to perform the work in one phase, rather than returning to the neighborhood after this project is complete and disrupting the residents a second time, within the same area.
The unit prices for the additional work have been evaluated and are considered favorable in comparison to recent contracts awarded for similar work. The areas selected for this change order are based on the proximity to the construction being completed and the impact the current contract is creating to the selected areas. Capitalizing on these unit prices, these areas to be replaced will be funded from CIP ST1806 Pavement Rehabilitation.
The original contract amount for CIP DR1701, Jess Pirtle Side Streets is $1.746M. Change Order No. 1 in the amount of $38,013 was a deduct change order. With this proposed Change Order No. 2, the total contract amount is $2.037M, which is 16 percent of the original contract. Subsequently, an additional 60 days is being added to the contract time to complete the necessary pavement improvements.
The Engineering and Public Works Departments recommend that the City Council authorize the approval of Change Order No. 2 for additional pavement replacement areas for CIP DR1701 Jess Pirtle Side Streets in the amount of $328,737.15 and approve a budget amendment of $328,737 from CIP ST1806 Pavement Rehabilitation Project to CIP DR1701 Jess Pirtle Side Streets.
