2. Call Meeting to Order
Chair Nejedly called the meeting to order at 2:00 p.m.
3. Public Comments - No public comments.
4. Items for Committee Recommendation to Board
a. Review draft Position Paper to award a construction contract in the
amount of$2,718,025 to Andes Construction, Inc., the lowest responsive
bidder for the Lafayette Sewer Renovations, Phase 14, District Project
8459; consider exemption from the California Environmental Quality Act
(CEQA); and authorize up to a 15-percent contingency
Mr. Lopez provided a brief overview adding that in consideration of recent
competitive bids received on other projects, the original engineer's
estimate had been lowered to $3.65 million. This project also received
competitive bids; the majority less than the amended engineer's estimate.
Andes Construction has previously worked for the District and has been
bidding on other District sewer projects since that time. He stated that it is
important to get the contract in place to begin the work in order to meet
City of Lafayette paving deadlines. As this project will come in under
budget, the $1 million of unused funds will be returned to the program
project placeholder for other sewer project needs.
COMMITTEE ACTION: Recommended Board approval.
5. Other Items
a. Receive report on Central San's As-Built Drawings Program
This report was provided in response to prior Board Member requests and
inquiries about the past and current practice of as-builts (a.k.a. record
drawings). With that background provided, Mr. Lopez continued with the
presentation included in the agenda material.
He shared that two-dimensional (2D) Computer-Aided Design (CAD)
modeling has been the Central San standard for quite some time, and the
District has recently been using more 3D Building Information Modeling
(BIM) and 3D CAD for more complex treatment plant projects. A
collaboration of staff, that includes technicians, survey and asset
management staff, are working on creating a standard for 3D CAD and
BIM. It takes a lot of effort to upgrade to the next stage, but this will
provide upfront beneficial information that can be included in design
compared to finding things out later in the field.

Mr. Lopez continued with an explanation of other applications that staff is
monitoring and preparing for compatibility set-up in the future, such as 4D,
5D and 6D BIM applications.
4D BIM is being used by the District's construction management
consultant (MWH Constructors) on the Solids Handling Facility
Improvements project. They are using such modeling to verify that project
constructability timelines and constraints are achievable. As an example,
he shared an impressive video (embedded in the presentation) that MWH
Constructors used to view a timeline vs. construction in order to see how
the construction progress would look based on the schedule provided by
the design consultant. He noted that this modeling tool has been very
beneficial on the Solids Handling project and will be a useful tool for future
large-scale projects.
As 4D BIM gives a schedule analysis, it was explained that 5D ties in the
cost component and cash flow, and 6D further adds the asset
management factor at the end of the project (i.e., record drawings,
manuals, startup and commissioning).
Due to a lack of robust record keeping in the past, and missing record
information in the plant, especially piping, Member Pilecki asked what staff
is doing in areas where information is vague that may have serious
consequences adjacent to other projects being worked on. Mr. Lopez
responded that some knowledge has been acquired from prior staff and
that an underground piping system project provided the opportunity to hire
a firm to locate piping that was tied into the District's GIS GeoPortal
system. The Planning Department is continuing the effort and will issue a
Request for Proposal soon to tie more pieces together and continue to
update the GeoPortal system project by project. It was acknowledged that
such an undertaking requires a lot of time and effort.
Member Pilecki asked staff to consider adding information to the
presentation about what staff is doing to recover information that is not on
a drawing, stating that it would be important information to share with the
Board. Mr. Lopez stated that he will add a slide, also noting that it cannot
be achieved in one project alone, that future projects will continue to build
the information one piece at a time.
COMMITTEE ACTION: Received the report.

b. Receive update regarding current capital program construction projects
during COVID-19
Mr. Lopez indicated that staff has continued to move forward with design
and construction of several projects that will-be or have-been bid, and
projects that will-be or have-been awarded since March with the shelter-in-
place order. As health directive orders evolved, such updates were
incorporated into project requirements. Mr. Lopez provided an overview of
some projects and various measures taken during this time, as shown in
the presentation included in the agenda material, and he responded to
various Committee inquiries.
Of note, it was shared that,just today, the upgraded Emergency Sludge
Loadout Facility (ESLF) was being tested by loading sludge in the silos for
the first time and that the isolation gates worked as planned. More
Operations staff are returning onsite this week and will be working on this
project, facility testing will commence tomorrow. This facility is critical to
the Solids Handling project.
The Server Room Relocation project update generated some discussion.
In particular, roof improvements and HVAC (heating, ventilation and air
conditioning) needs. As it pertains to easing future roof leakage concerns,
the roofing system has been updated and some penetrations had to be
redone. The contractor brought in a new subcontractor to properly
complete these improvements. The new server room has been tested for
adequate cooling needs because the room must be kept cold. Three
Liebert cooling systems were installed. Approximately 1.5 systems are
needed, thus, the third is mainly for backup. Staff has a lot of confidence
in the effort that has gone into ensuring the room is well constructed.
At time of award in April, the Outfall Improvements-Phase 7 project
planned for a two-step Notice to Proceed (NTP) process due to the onset
of pandemic restrictions. Staff was pleased to announce that the
contractor started field activity this week after receipt of the second NTP
and obtaining all necessary permits.
The Danville Sewer Renovations-Phase 3 project requires a considerable
amount of coordination as portions of the project require access to work
on private properties. The initial mainline street work is underway,
continued with reconnection to homes, estimated to be done by August.
Inspector oversight will be more imperative with COVID-19 safety
measure monitoring. Member Pilecki inquired about measures to keep the
public away from construction activities. Mr. Lopez replied that the
contractor is blocking off areas to the public; public outreach continues,
and he opined that it seems well understood by all that social distancing is
important.

Chair Nejedly stated he is amazed at what is being accomplished during
this time and asked that his appreciation be shared with staff.
COMMITTEE ACTION: Received the update.
C. Receive a verbal update on the status and testing of the Emergency
Sludge Loading Facility
An update of the ESLF was covered in the prior item's presentation.
Mr. Petit advised that one of the facility silos was being loaded with sludge
today and will be tested with loading trucks tomorrow. In consideration of
the shelter-in-place orders, he asked if the Committee was still interested
in a tour and, if so, asked their preference of viewing during loading
activities or at any time. The Committee responded that they would like a
tour of the facility, however, they are flexible in coordinating an appropriate
time to come onsite. Mr. Petit stated that in the interim, he will ask staff to
video the sludge loading activity at the improved facility for viewing later.
COMMITTEE ACTION: Received the information.
