BACKGROUND

The Master Plan of Drainage has identified a number of deficiencies with the City’s storm drain system. One of the deficiencies identified that some pipes have deteriorated to such a degree that their ability to convey drainage has been reduced, and pipe collapse is possible. Corrugated metal pipes (CMP) are most likely to deteriorate. In April 2005 the City Council awarded a construction contract (Phase I Lining Project) to repair deteriorated CMP pipes in the city by lining. The Phase I lining project repaired 28 sections of storm drain pipe without noticeable traffic delay.

Physical deficiencies within storm drains are confirmed by visual inspection. This is accomplished by sending a video camera mounted to a remote operated electric cart through the pipe and recording the condition observed. Deficiencies are easily identified through this process. During the Phase I Lining Project staff determined approximately 80% of the City’s 200 CMP would need to be lined in the future.

In August 2005 voters approved the Storm Drain User Fee to fund repairs that are needed to the City’s aging storm drain system. Funds are available and budgeted to perform repairs to the storm drain system through lining.

ANALYSIS

Project plans were advertised and sealed bids were received and opened at 10:00 a.m. on August 15, 2006. SANCON Technologies, Inc. submitted the only responsible and responsive bid. The bid summary follows:

 

BID SUMMARY
CONTRACTOR BID
AMOUNT
SANCON Technologies, Inc.
$179,920.60
Engineer’s Estimate
$160,000.00

The bid was reviewed for consistency with bid requirements. SANCON Technologies, Inc. has worked with the city in the past and staff is satisfied with their performance. The bid documents, bonds, and other contract documents are in order and their contractor’s license is current.

Although the low bid exceeds the Engineer’s Estimate by approximately 12%, the discrepancies have been generally identified. Material cost fluctuations account for the difference between the Engineers Estimate and the low bid.

This project requires inspection services. Charles Abbott Associates is familiar with the process that will be used during construction. Staff is comfortable with Charles Abbott Associates ability to provide inspection services. Staff recommendations including authorization to use the firm of Charles Abbott Associates for inspection services.

CONCLUSIONS

Adopting Staff’s recommendations will award contracts to SANCON Technologies, Inc and Charles Abbott Associates for construction and inspection services respectively.
