5.a .
ISSUE: On July 17, 2012, four (4) sealed bids were received and opened for the
Nondestructive Potholing of Underground Utilities, Contract 039457ENG. The Board of
Directors must award the contract or reject bids within 50 days of the bid opening.
Authorize the General Manager to execute the contract documents subject to
SUBMITTAL requirements.
RECOMMENDATION: Find that the project is exempt from the California
Environmental Quality Act (CEQA), award a construction contract to Arrow
Construction; authorize the General Manager to execute the Contract Documents
subject to favorable review of insurance certificates, bond submittals, appropriate
Contractor license, and any other required submittals (SUBMITTALS).
FINANCIAL IMPACTS: Approximately $122,175 per year, or $366,525 for three years.
ALTERNATIVES /CONSIDERATIONS: Reject all bids and rebid the project, or
continue issuing individual contracts each time nondestructive potholing of underground
utilities is needed, which is not efficient, therefore, is not recommended.
BACKGROUND: The Capital Projects Division performs approximately 200 potholes
each year as part of the design of collection system projects. The purpose of potholing
is to expose underground utilities along the proposed sewer alignments at points of
potential conflicts. The results are used to evaluate alternatives during design and to
minimize change orders during construction.
Staff has found that bidding the nondestructive potholing services on a periodic basis
results in a lower overall cost and a significant reduction in paperwork associated with
negotiating and issuing separate contracts. The purpose of the bid request is to

establish a unit cost for each portion of the work for certain potential projects, while
obtaining the lowest overall cost for the District.
District staff prepared the bid documents for the work. The Engineer's estimate for
work of the Nondestructive Potholing of Underground Utilities, Contract 039457ENG, is
$84,000 per year. This project was advertised on June 29 and July 5, 2012. Four (4)
sealed bids ranging from $122,175 to $170,195 were received and publicly opened on
July 17, 2012. The higher- than - expected bid prices are due to rising costs of
performing air vacuum excavation. The Engineer's cost estimate was based on the
District's last contract, and was not sufficiently adjusted to reflect current higher costs of
vacuum potholing.
The Engineering staff conducted a technical and commercial review of the bids and
determined that Arrow Construction is the lowest responsive bidder. The initial contract
amount will be $122,175. District staff may exercise options for additional one -year
periods (up to two) at the bid prices, provided that the initial work is successful and the
prices are still favorable to the District. A summary of bids received is shown in
Attachment 1.
Staff has concluded that this Contract is exempt from the California Environmental
Quality Act (CEQA) under District CEQA Guidelines Section 15262 since it will provide
information for design of sewer improvements and will not have a legally binding effect
on later activities. The Board of Directors' approval of this award of Contract will
constitute an independent finding that the Contract is exempt from CEQA.
RECOMMENDED BOARD ACTION: Staff recommends the following:
Find that the project is exempt from CEQA,
2. Award a contract in the amount of $122,175 to Arrow Construction, the lowest
responsive bidder, for providing nondestructive potholing of underground utilities
services for a one -year period with an optional extension for two additional
one -year periods, and
3. Authorize the General Manager to execute the Contract Documents subject to
SUBMITTAL requirements.
