3. Review draft Position Paper to award a construction contract to EXARO
Technologies Corporation in the amount of $58,480 per year up to three years
totaling $175,440 for the construction of the District-Wide Survey Monument
Installation, District Project 2017-01
Mr. Lopez reviewed the information in the draft Position Paper included in the
agenda materials. He clarified that the contract was a unit price blanket contract
for survey monument construction services.
Member Causey asked if the District has worked with this contractor in the past.
Mr. Lopez responded that EXARO held a previous monument contract, as well
as performed potholing for the District, and their work has been satisfactory.
Chair Nejedly ask about changes to unit pricing compared to last year. Mr. St.
John explained that pricing has increased significantly over the last six years and
that last year had the largest increase. He noted that contractors are in high
demand because, in order to remain compliant with State laws, counties and
cities are keeping them busy.
Member Causey asked what the average cost is to restore a monument.
Mr. St. John responded that the construction cost is approximately $3,000, not
including staff time.
COMMITTEE ACTION: Reviewed and recommended Board approval.
4. Review draft Position Paper to authorize the General Manager to execute a
Professional Engineering Services Agreement with V.W. Housen and Associates
with a cost ceiling of $780,000 for the preliminary design of the Pump Station
Upgrades Project, District Project 8436
Mr. Petit introduced staff present for this topic and consultant Dana Hunt from V.
W. Housen. He noted that Ms. Schmidt will be giving an abbreviated version of
the presentation included with the agenda materials.
Ms. Schmidt explained that the project includes the Martinez, Fairview, Maltby,
Flush Kleen, Orinda Crossroads, and Moraga pumping stations, and the Concord
Metering Vault station. She gave an overview of the upgrades, describing each
pump station and its history of renovations and major work. She stated that aging
assets, reliability and sustainability are the drivers for this project and reviewed
the major scope of work. Ms. Schmidt also reviewed the proposal and selection
process as well as the project schedule.
Mr. Petit noted that language addressing that this project will be exempt from
CEQA will be added to the Position Paper.

In response to a question from Member Causey, Mr. Petit said the project will
have a single project number, per the Fiscal Year 2017-18 Budget, and that the
number also includes the Concord Metering Vault, which he added at the last
minute to the pump station upgrades project.
Chair Nejedly asked Mr. Gonzalez about the condition of the pump stations and
asked for the total running hours on the Waukesha diesel engine (circa 1959).
Mr. Gonzalez generally described the problems and conditions of the pump
stations, noting that the longer the work is delayed, the more it will cost. He said
he will get back to the Committee with the number of hours for the diesel
engines.
Member Causey expressed concern that the consultant, V.W. Housen, is a small
company for this large project. Mr. Petit noted that Ms. Hunt, who is a very
experienced project manager with extensive pump station design, has a very
capable team supporting her work, such as HDR Engineering, Inc., and Arc Sin
Engineering for electrical engineering, as well as other Subconsultants.
COMMITTEE ACTION: Reviewed and recommended Board approval.
5. Receive Change Order Log, Quarterly Reports, and Bid Schedules to compare
budgeted versus actual costs, including project status and close-outs
Mr. Lopez reviewed the schedule, noting two potential change orders above
$50,000 and may reach Board level authorization. The first is for the Headworks
refurbished screens, which was originally scheduled to take place at the end of
the project; however, the current plan is to have the screens fully operational this
upcoming wet season. The change order is expected to reach $95,000 and the
General Manager has authorized the work to avoid any potential delay in the
project. The second change order is for failed corroded flight rails, on two
primary sedimentation tanks. Staff will be looking to repair or replace the bottom
rails this summer. Staff has asked three current treatment plant contractors to
provide quotes.
Member Causey asked if contingency funds will be used for the primary tank
change order. Mr. Lopez said yes and there’s adequate project contingency.
Member Causey questioned why not just open a new project, especially if it is a
stand alone project. The rail replacement was projected under the Mechanical
and Concrete project in the Capital Improvement Budget, new project. The
change order can be charged to this project.
COMMITTEE ACTION: Received the reports.
6. Receive list of Scheduled/Parking Lot items
COMMITTEE ACTION: Received the list.
