DISCUSSION:
Overall Contract Cost/Time Summary
Work for this contract included replacement of essential traffic signal equipment and
infrastructure to ensure reliability of the traffic signals at the Coast Highway /Marguerite
Avenue and Superior Avenue/Ticonderoga Street -Nice Lane intersections. Additionally, the
intersections were modified to add left -turn phasing to enhance the left -turn movements
during peak summer periods.
The contract has now been completed to the satisfaction of the Public Works Department.
A summary of the contract cost is as follows:
Original bid amount:
Actual cost of bid items constructed:
Total change orders:
Final contract cost:
$201,672.00
$202,374.00
$5,881.10
$208,255.10
The final construction contract cost was approximately 3.3% above the original bid amount.
The majority of this additional cost increase was related to discovery of unknown
underground utilities that required relocation of equipment and installation of additional
temporary traffic control equipment.
The delay in project completion was due to incorrect traffic signal arms being delivered by
the manufacturer. Generally traffic signal poles and arms can take up to 15 weeks to be
delivered. Fortunately the vendor was able to quickly locate and deliver the correct
equipment to minimize the delay.
A summary of the project schedule is as follows:
Estimated Completion Date per 2012 Baseline Schedule December 21, 2012
Project Awarded for Construction November 13, 2012
Contract Completion Date with Approved Extensions May 22, 2013
Actual Substantial Construction Completion Date May 15, 2013
