Approval and authorization to execute Change Order #1 with Envision Civil Contractors, LLC. on Construction Contract SW1921; Willow Springs IV Storm Sewer
End
Background:
Council authorized this project at the recommendation of the Drainage Advisory Committee on December 17, 2019, Agenda No. 19-1438. Council authorized expenditure of 2018 General Obligation Bond - Proposition 6 funds for the construction of certain drainage improvements to an existing storm sewer system running across, through and upon the residential property located at 8105 S. Beech Avenue in the amount not to exceed $95,000.00.
The work consists of construction of new 30-inch diameter drainage pipes, three new manholes, outlet headwall and solid slab sod to improve erosion issues caused by two public storm sewers located at 8105 South Beech Avenue in the Willow Springs IV Subdivision.
The project was advertised on August 6 and August 13, 2020. The lowest responsible bid was Envision Civil Contractors, LLC for $74,452.95. Construction funding for the project is available through the 2018 General Obligation Bond - Proposition 6, Adams Creek Basin, under Project No. SW1921.
Subsequently, Envision Civil Contractors, LLC was issued a Notice to Proceed, began work promptly, and is still underway with construction.
This Change Order #1 addresses the following additions to the contract:
CO1-1: During the course of the project, it was found that the contractor needed to install additional Rip-Rap along the outfall of the new storm sewer installation to properly stabilize the outfall from erosion. Rip-Rap was not in the original valuation of the contract and thus this additional erosion protection is being added via a change to the project at a negotiated rate of $40.35 per ton.
Contract Time Adjustments:
- No additional time required
