The City Administration is requesting City Council approval to authorize the City Manager to award and enter into a contract with Black Horse Bridge Construction, Inc. for the SUM-Brandywine Drive and Blackberry Drive Bridge Rehabilitation over Brandywine Creek (PID 91974). The Engineering Staff is requesting a 10% contingency for any unforeseen issues that may arise during construction. The total amount would be $932,047.60.
Total Contract = $932,047.60 ($847,316.00-base + $84,731.60-contingency)
Also included in the bid were the following alternate substitution items that can be added at Council’s discretion:
1. Decorative Rock Channel Protection (RCP)(Bid $250/SY-$84,500.00), in lieu of standard RCP (Bid $100/SY-$33,800.00)- add $50,700.00 = $898,016.00
2. Sod - Staked (Bid $20.00/SY-$16,940), in lieu of seeding and mulching (Bid $14.00/SY-$4,718) - add $12,222.00 = $859,538.00
3. Sod - unstaked (Bid $18.00/SY-$3,600.00), in lieu of seeding and mulching (Bid $14.00/SY-$4,718.00)- deduct $1,118.00 = $846,198.00
Due to the project coming in over the Engineer’s estimate, staff is also requesting an appropriation in the amount of $162,396.60. If Council would like to go with Alternates 1 and 2 then an appropriation in the amount of $231,610.80 would be needed.
