Executive Summary
The City of Santa Monica is seeking a California licensed well drilling contractor to
resources and supporting the innovative City Services Building project, which has as a
design goal of meeting the Living Building Challenge requirements of net zero water
and energy for the project. Specifically, the contractor would drill a boring approximately
650 feet deep in order to evaluate the presence of fresh groundwater. If fresh
groundwater is discovered, a portion of the boring would convert to a shallow water
supply well at a location on the northwest side of City Hall. This well would be utilized
as a secondary source of water for the City Services Building Project. In April 2016, the
City solicited bids for such services. After reviewing the five bids received, staff
2
recommends awarding the contract to BC in an amount not to exceed $269,037.
Background
A primary objective of this project is to drill and obtain hydrogeologic data from a deep
exploratory boring which would be used to assess the qu
groundwater resources in this portion of the Coastal sub basin. A secondary objective
of the project, if fresh groundwater is present, is to construct a shallow, small-diameter
potable-supply water well to support the proposed City Services Building project (CSB).
Once tested and permitted, groundwater from the well would be treated and utilized as
a supplemental onsite water source for the CSB. The design of the potable well would
1 of 4
be based on the hydrogeologic data obtained from the exploratory boring.
The proposed deep exploratory boring would be drilled using standard water well drilling
methods to collect samples, evaluate the subsurface geology, and obtain geophysical
logging data from the borehole. A critical piece of data the City would collect is whether
fresh groundwater water exists in the subsurface at this location, and if so, the depth to
the subsurface interface between fresh groundwater water and saline groundwater. A
direct benefit of this data is that it would -
term water self-sufficiency.
The exploratory boring, and any subsequent potable supply well, would be co-located in
the same borehole on the west side of City Hall (see Figure A). This location was
selected in consultation with the CSB team (Architecture Services, Office of
Sustainability and the Environment, and Water Resources), and the State Water Quality
Control Board, Division of Drinking Water. For the purpose of permitting, the potable
supply well, if constructed, would be designated Santa Monica City Hall Well No. 1
(SMCH Well No. 1).
If determined to be feasible, the new well would be constructed in compliance with local
codes and regulations and in accordance with the following documents: State of
California Water Well Standards, Bulletin No. 74-81, dated December 1981, and its
Draft Supplement Bulletin No. 74-90 dated June 1991; Sections 13800 through 13806
of the California Water Code, and; American Water Works Association (AWWA)
Standard for Water Wells (AWWA A100-06). A geological consultant previously
retained by the City (Richard Slade & Associates) would be on site to supervise the
drilling and water well construction activities.
Discussion
The proposed CSB is planned to be an award winning self-sustaining facility that would
employ innovative design and technical applications to achieve net zero energy and
water. Net zero water would be primarily achieved through the harvesting and
treatment of rainwater on site and the use of composting toilets almost eliminating water
use for flushing. When precipitation is scarce, the project would rely on a supplemental
2 of 4
water source provided by a shallow onsite groundwater well. The fresh groundwater
would be treated onsite to potable standards acceptable to the State Water Resources
Control Board Division of Drinking Water prior to use. The recommendation in this
report would result in, among other things, the collection of necessary and valuable
inable water planning and, if feasible,
construction of the necessary shallow supply well for the CSB project.
Vendor Selection
On April 14, 2016, the City published Notices Inviting Bids to furnish and provide drilling
and well construction work in accordance with City specifications. The bid was posted
on the City's on-line bidding site, and notices were advertised in the Santa Monica Daily
Press in accordance with City Charter and Municipal Code provisions. A total of 32
vendors downloaded the bid. Five bids were received and publicly opened on May 19,
2016. Bid results are as follows (not including a 10% contingency):
BiddersBase Bid
2
BC Environmental $ 244,579
ABC Liovin Drilling $ 273,084
Cascade Drilling $ 274,710
Yellow Jacket Drilling $ 291,422
Hydro Resources West, Inc. $ 305,500
Bids were evaluated based on the criteria in SMMC 2.24.072, including price, previous
experience, ability to deliver, quality of product, and compliance with City specifications.
2
Staff contacted references that were provided by BC Environmental for similar projects
in La Puente, CA and Santa Barbara, CA. Reference agencies reported that the work
was produced in a timely and cost-efficient manner where quality was maintained
2
throughout. Staff also verified that BC Environmental's contractor license is active and
2
in good standing. Based on these criteria, BC Environmental, the lowest bidder, is
recommended as the best bidder.
Timeline
Work is scheduled to begin in the third quarter of 2016, and drilling operations would
take approximately two to four weeks to complete. During this time the staff vehicles
3 of 4
that normally park on the northwest side of City Hall would be temporarily directed to
other parking locations. The schedule of work would be finalized and coordinated in
consultation with the various offices which occupy City Hall. A work notice fact sheet
would be distributed in advance of the planned work.
