BACKGROUND

During the storms of 2005 the inlet to the storm drain located at the foot of McCarroll canyon was impacted by debris that accumulated during the heavy rainfall events. The inlet’s ability to collect runoff was impacted by this debris and flooding resulted. A plan was developed to minimize the possibility of flooding due to a restricted inlet. This plan included the installation of two gabion walls and two timber walls. The gabions and walls have been designed to collect rocks and debris during heavy rainfall events prior to reaching the storm drain inlet. Plans and specifications were developed however the city did not have needed right of way to install the improvements. The needed right of way was obtained and the project is ready to be awarded and constructed.

ANALYSIS

Project plans were advertised and sealed bids were received and opened at 10:00 a.m. on August 17, 2006. S.P. Pazargad Engineering Construction, Inc., was the lowest responsible and responsive bid. The bid summary follows:

BID SUMMARY

Engineer’s Estimate

$ 90,000

The bid was reviewed for consistency with bid requirements. References provided by S.P. Pazargad Engineering Construction, Inc. were interviewed. The three references contacted reported the firm was responsible and diligent in completing the contract work. Staff has not worked with S.P. Pazargad Engineering Construction, Inc. in the past, however their bid documents, bonds, and other contract documents are in order, their contractor’s license is current and references have been checked.

Although the low bid exceeds the Engineer’s Estimate by approximately 9%, 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.
