The low total bid amount was approximately fourteen percent (14 %) below the engineer's
estimate of $540,500.00. The current competitive construction market most likely
contributed to the disparity between the received low bid and staff's cost estimate. The
engineers estimate was developed based on the unit prices received from last year's
concrete reconstruction project.
An additive bid item to replace existing handrails at San Miguel Park was included in the
bid package. After review with General Services Department staff and evaluation of the
bid pricing, Staff recommends including the Additive Bid Item, Al, to the contract at a
cost of $13,000.00, resulting in a total contract of $475,370.00.
The low bidder, Grigolla & Sons, possesses a California State Contractor's License
Classification "A" as required by the project specifications. A check of their references
indicates they have satisfactorily completed similar concrete projects in past few years.
Public Works' staff believes Grigolla & Sons can successfully complete this year's
concrete reconstruction project.
Given the favorable project unit prices by Grigolla & Sons, staff recommends Council to
establish a twenty percent (20 %) contract contingency to be included in the contract
award, totaling $95,000.00. Those added funds will provide an opportunity for the City to
take advantage of the low unit prices to perform additional concrete repairs at other
locations.
This project consists of existing sidewalk, medians, driveways, curb and gutter, alley
approaches, curb access ramps; replacing concrete stair cases; pruning tree roots; and
installing new tree root barriers per City standards primarily within the Eastbluff Community
and Balboa Island. Pursuant to the Contract Specifications, Grigolla & Sons will have 85
consecutive working days to complete the construction.
ENVIRONMENTAL REVIEW
Staff recommends the City Council find this project exempt from the California
Environmental Quality Act ( "CEQA ") pursuant to Section 15302 (Replacement or
Reconstruction) of the CEQA of the CEQA Guidelines, California Code of Regulations,
Title 14, Chapter 3, because it has no potential to have a significant effect on the
environment.
PUBLIC NOTICE
The Notice Inviting Bids was advertised in the City's official publication and in
construction industry publications. Prior to starting work, two City prepared notices will
be distributed by the contractor to the nearby residents. The first notice will be
distributed ten days before starting work and the second notice 48 hours prior to starting
work.
