SECTION 1 PROPOSAL OVERVIEW & SUMMARY
1.1 Project Background and Understanding
1.11 Background
SRT Consultants (SRT) understands that the City of Pacifica (City) received in 2011 a Cease and
Desist (CDO) from the San Francisco Bay Regional Water Quality Control Board (Regional Board)
related to insufficient capacity in its sewer collection system causing sanitary sewer overflows (SSOs).
The City’s Collection System Master Plan (Master Plan, RMC Water and Environment, RMC) in
October 2011 proposed a strategy to eliminate SSOs that includes upsizing select sewer pipes in
the collection system, installing a fourth pump at the Linda Mar Pump Station, and constructing
an equalization basin with a capacity of 2.1 million gallons (MG) immediately upstream of the
Linda Mar Pump Station. Only the equalization basin is part of the present project along with all
appurtenances required for a fully operational system: pipelines, equipment, controls, etc.
The City subsequently developed the 2015 Wet Weather Equalization Basin Site Feasibility Evaluation
(1015, Feasibility Study, RMC) to evaluate several locations for siting the equalization basin. In
August 2015, the City requested an addendum to the 2015 Feasibility Study to evaluate an additional
site, referred to as Site Alternative 2C (Upper Skate Park Parking Lot). This new site is, among other
benefits, located further away from private residences. The City Council at its September 28, 2015
meeting selected Alternative 2C as the preferred site with an estimated project cost of $14.9 million.
On October 12, 2015, the City Council awarded the Equalization Basin’s Project and Construction
Management Services (PM/CM) contract to 4LEAF, Inc (4LEAF). The PM/CM will administer the
project from the environmental process through construction. The PM/CM will also perform the
final soil investigations at Site 2C.
The City is now proceeding with hiring an engineering team to design the new equalization basin.
The City’s intent is to designate the successful team on November 23, 2015. Per the CDO, the project
must be constructed and operational at the latest by December 31, 2018. However, the City has
targeted June 30, 2018 for completion of the project.
1.12 Project Understanding
While preparing this Proposal, we have carefully reviewed previous engineering work performed
for the project. We have also visited the proposed site several times in an effort to get more familiar
with the project. The following sections are based on this preliminary review and present our
understanding of the project’s technical challenges and our proposed methodology to address them.
Schedule
SRT’s Proposal includes an aggressive yet realistic project schedule based on the following main
assumptions:
1. SRT sees the Preliminary Design Phase as an opportunity to compare several alternatives
SRT City of Pacifica | Equalization Basin Project Design Services 3
consultants
CITY OF PACIFICA //
EQUALIZATION BASIN PROJECT DESIGN SERVICES
for the basin location and configuration. Only Site 2C approved by the City Counsel would
be considered. It is assumed that the preferred basin location and configuration would be
selected and approved by the City and PM/CM 4LEAF would make within two months from
the Notice-to-Proceed (NTP) to allow for the 30% design to proceed.
2. 4LEAF final soil investigation would provide sufficient information to design the basin
foundations and would be available by December 2015.
3. Environmental permits and all associated construction mitigation measures available to SRT
prior to initiating the 90% design submittal, i.e. by mid-August 2016.
Soils and Basin Foundations
We understand that 4LEAF will perform additional geotechnical investigations within the proposed
footprint of the basin at the Site 2C to confirm the soil conditions. SRT recommends a minimum of
two borings within the basin footprint, one boring at the intersection of Linda Mar Boulevard and
De Solo Drive, and one boring every 300 feet along the proposed diversion pipeline alignments on
Arguello Boulevard and Balboa Way.
Based on the preliminary geotechnical work performed for this project, the basin foundations
design would need to account for high groundwater level, earthquake-related ground shaking and
liquefaction potential. The basin foundations would also need to be designed in conformance with
other soils characteristics yet to be determined, such as the bearing capacity and the estimated
maximum differential vertical settlement over the span of the basin diameter. SRT plans to proceed
with the basin foundation design in the early stages of the preliminary design following review of
the additional geotechnical investigation results.
Excavation Techniques
The 2015 Feasibility Study assessed various top-down deep excavation techniques and proposed
cutter soil mixing (CSM) with shotcrete structural walls and a cast-in-place concrete bottom/top slab
as the construction method. As it is with most top-down, deep excavation techniques, CSM requires
large specialty equipment and is offered by a select few specialty contractors. While this method
appears viable, other construction methods should be considered to minimize cost of construction.
SRT proposes to develop construction bid documents that would provide the contractor an option
of pricing several construction techniques, including but not limited to CSM, diaphragm walls,
CCMJ Milled Joint System diaphragm walls, DeWaal Piles, and/or secant piles. By providing options,
competition would be introduced into the bid process through an expansion of the deep excavation
specialty contractor pool.
The SRT Team will identify the most viable excavation options for the chosen basin configuration
based on the final soil investigation results and present them to PM/CM and the City. Construction
bid documents and material specifications that present multiple construction alternatives would
then be developed.
Groundwater
SRT proposes to design the basin to resist buoyancy forces generated by groundwater level at
grade with a 20% safety factor in conformance with the industry standards. This corresponds to
SRT 4
consultants
CITY OF PACIFICA //
EQUALIZATION BASIN PROJECT DESIGN SERVICES
a buoyancy factor of 1.20. SRT’s preliminary calculations based on the geometry proposed in the
2015 Feasibility Study, indicate a buoyancy factor significantly less than 1.00. This means that the
weight of the structure is not sufficient to counteract buoyancy forces: i.e., the structure would be
at risk of structural damages due to floating, unless designed to include special features to prevent
vertical displacement. Special features could include covering the basin with approximately 6 feet
of soil, or using helical anchor/piles.
Basin Configuration
As part of the Preliminary Design Phase, SRT proposes to review the configuration of the equalization
basin presented in previous studies and confirm if it is the most practical and cost-effective means
of creating 2.1 million gallons of storage capacity at the proposed site. Although a round structure is
inherently stronger for resisting lateral earth and hydrostatic groundwater pressure at great depths,
a structure with a greater surface area would not need to be as deep. For example, a rectangular
equalization basin that is 20,000 square feet in area (the size of the existing parking lot) would only
need to be 14 feet deep to achieve the required storage volume. Accounting for depth of cover, sewer
inlet elevation, and depth of foundation, the overall depth of the structure would be approximately
35 feet. This is much lower than the 75-foot deep structure described thus far. A shallower structure
would be significantly less expensive to construct as more conventional soil nail walls may be
employed, or the perimeter walls may be constructed by cutter soil mixing (CSM) and anchored
with tie back rods. Protecting a shallower basin against buoyancy would also be less costly.
The City selected Site Alternative 2C over Alternative 2A/2B since it was slightly further away from
the abutting private residences. Consideration of a larger surface area/shallower basin may require
construction closer to the residences. However, temporary sound walls and other means of reducing
workday noise during construction can be successfully employed to mitigate impacts to residents.

Pipelines
Previous studies identified two flow diversion points in the collection system where a portion of
storm-related flow would be redirected to the equalization basin. The diversion structures associated
with Site Alternative 2C are located on Linda Mar Boulevard and Arguello Boulevard to the south.
SRT included a preliminary pipeline alignment and profile in APPENDIX B of this Proposal.
Alternative Configuration Could Save Time and Money
Both diverted flow streams would combine into one pipeline winning northeasterly on Balboa
Way and cross Anza Drive. A narrow utility corridor exists between 1019 and 1023 Anza Drive.
Traditional cut and cover construction for this pipeline is not practical in this location since the
houses are very close to each other. Therefore, horizontal directional drilling (HDD), jack and bore,
or other trenchless means of installation would most likely be employed for this portion of the
pipeline. The depth of the diversion sewers may necessitate similar construction techniques for Del
Solo Drive, Arguello Boulevard and Balboa Way to avoid disruption of other utilities. In addition,
the sewer pipelines would need to be designed to maintain a 10-foot horizontal separation from
the potable water mains.
Process and Mechanical Equipment
The pumps required for the project would need to operate over a wide range of flows. SRT anticipates
that the two submersible pumps (one duty, one standby) would be variable speed and controlled by
variable frequency drives (VFDs). This would allow greater operator control and permit the pumps
to operate more efficiently during low flow conditions when the equalization basin is only partially
full. The static head will vary greatly as the water level in the equalization basin (as depicted in the
2015 Feasibility Report) fluctuates. The proposed configuration would require 75 to 100 HP, 460
volt, non-clog, explosion-proof pumps. A pump this size weighs approximately 2,000 pounds and
would require a small crane or boom truck to remove for maintenance and repair. We anticipate that
a high solids submersible chopper style pump would be selected for this application over standard
non-clog pumps. Grit, rocks, and other material may collect over time at the lowest point in the
equalization basin. Removing this material would be difficult in the deep structure since most sewer
vactor trucks are limited to about 28 feet of suction lift. Heavy wet grit nearly 80 feet deep would need
to be removed manually with buckets and a small crane or re-suspended with water and pumped
out by the submersible pumps, captured above grade in a settling tank, and transported to landfill.

Grease and floating material can be removed from the
water surface with conventional vactor trucks if the
equalization basin is full. A shallower, wider structure
would require significantly smaller pumps.
In an effort to control cost and improve the basin’s
reliability, the proposed design does not include
any valve/penstock controlling the basin fill. The fill
elevation would be set in the diversion structures and
the basin would fill each time the wastewater level
raises above the fill elevation inside the collection
system. Hence, while the basin draining is active and
requires pumping, the filling is entirely passive.
Odor control requires careful consideration due to
the proximity of private residences, Skate Park, and
the Pacifica Community Center. Previous studies
proposed an advanced odor control system including
an odor control bed and fans both pushing air into and High Pressure Fire-Hose
from the basin. SRT understands that odor control is
critical for the project but is also aware of its high capital and operations and maintenance costs. For
that reason, SRT would early on work with Operations Staff to determine whether an odor control
system is needed. Firstly, under normal operations, the equalization basin would be dry. In our
experience, the circulation of sewage through the collection system would create a negative pressure
in the basin that will draw fresh air through its vented manhole covers. That negative pressure might
also be generated by the odor control system at Linda Mar Pump Station, if any. When the basin
is in use, sewage will be diluted with stormwater inflow and groundwater infiltration. This type of
sewage has low organic matter content and low potential for generating offensive odor. Secondly,
the basin could be flushed after each use to avoid stagnant sewage at the lowest point of the basin.
On another hand, if a very deep basin is selected as proposed by previous studies, Operations
Staff might see beneficial to have a fixed venting system able to force air to the lowest, potentially
oxygen-deprived depths prior to accessing the basin. One option might be to install corrosion-
resistant ductwork inside the basin and to include provisions for future installation of an odor control
system. Operations Staff could then use the ductwork to connect a temporary ventilation fan prior
to accessing the basin. If needed, the odor control system would maintain a negative pressure on
the basin drawing fresh air in from the south end of the structure and discharging it into the odor
control system on the north side away from the residences. No supply fans would be needed and
exhaust fans only would maintain the needed negative pressure in the basin in this scenario.
Tipping troughs for washdown, as discussed in the 2015 Feasibility Report, are not recommended.
They would need to be installed above the maximum wastewater level, i.e. at least 60 feet above the
slab and water falling from that height may damage the concrete slab. They may even require internal
walkways and platforms for access. A 2-inch high-pressure fire hose system with turrets would be
more effective and more robust for washdown operations. In developing the design criteria as part of
the preliminary design, consideration would be given to fixed internal wash-down hose connections

at the top and at least one at the bottom of the basin. Washdown water 2-inch hose (minimum)
could be deployed from a hose reel secured on the roof of the basin and connected with a reduced
pressure backflow preventer to a nearby hydrant. Alternatively, a new potable water service may be
installed to provide washwater for the new basin.
Instrumentation, Electrical, Controls, and SCADA Integration
The basin would require a new 480V PG&E service that is expected to be located on Crespi
Drive. Backup power from engine-driven generator(s) would need to be located close to the new
aboveground control building. In the likely event of a power failure during a heavy rainstorm, an
automatic transfer switch (ATS) would detect the loss of line power and automatically transfer
the power load to the generator. Pumps, lights, odor control systems, and SCADA would run
uninterrupted on the generator until normal line power is restored. Consideration should be given
to natural gas fired generators in lieu of diesel for air quality permitting reasons.
All electrical equipment within the basin must be Class 1 Division 1 explosion-proof as defined by
the NFPA and NEC including pumps, lights, and emergency disconnect switches. Fan motors and
other electrical items would be located outside of the basin for ease of maintenance, electrical safety,
and to avoid the corrosive atmosphere. All internal conduits and boxes would need to be sealed
PVC coated ridged steel to resist corrosion and prevent the migration of potentially explosive sewer
gases to the motor control building.
Instrumentation would include level measurement in the basin (transducer and floats) and flow
measurement on the discharge line of the pumps. Submerged pressure transducers could be used
for level measurement, however an ultrasonic device that does not need to be in the water would
be more beneficial.
SRT anticipates that the equalization basin would be connected to the existing SCADA system
through Linda Mar Pump Station.
Parking Lot Improvement
SRT understands that the entire existing Skatepark parking lot would need to be reconstructed
following construction. The existing parking lot is heavily used by the Skatepark and Pacifica
Community Center and, if possible, the parking lot would be reconfigured to improve circulation
and increase the number of parking stalls. The new parking lot would remain within the same
footprint as to not affect the surrounding environmentally sensitive areas. The new parking lot would
incorporate three ADA parking stalls, ADA path of travel, ADA ramp, storm drainage facilities, low
impact development facilities to treat stormwater and drought tolerant vegetation. The new parking
lot would also accommodate the new aboveground facilities associated with the equalization basin
(control building, back-up generator, odor control system).
Access and Safety
The equalization basin, as currently envisioned, is an exceptionally deep (nearly 80 feet) structure
that would be difficult and dangerous to maintain. The equalization basin would be classified as a

EQUALIZATION BASIN PROJECT DESIGN SERVICES
Permit Required Confined Space and will require a 3-person crew for any entry.
Due to the highly corrosive atmosphere, all internal anchors and metal components would have to be
316 stainless steel and platforms and handrails be fiberglass reinforced plastic (FRP). A ladder to the
bottom of the basin would require a landing every 20 feet per OSHA (or 30 feet if a cage is provided).
A cage may interfere with the workers safety harness and retrieval cable. Special retrieval hoists and
davit cranes would be required since typical retrieval cables are only 50 feet long. A shallower but
wider structure would be preferrable for maintenance.
Public Outreach
The SRT Team understands that public opinion of the Project is critical to ensuring that the project
is completed successfully and on time. Providing support to the City/4Leaf with public outreach
meetings and Board workshops concurrently with the permitting and design, SRT will assist the
City/4Leaf in advancing the Project with the goal of having a construction-ready design by late
2016. It will be important to provide educational opportunities to the public regarding the Project,
and SRT has a successful track record of utilizing public outreach service to expedite projects, using
tactics such as field trips for interested parties to the construction site, presentations catered to the
public, and one-on-one discussions.
1.2 Project Approach and Work Plan
SRT will provide the professional engineering design services according to the four tasks outlined in
the City’s RFP. The following section expands on these tasks and presents SRT’s strategy for meeting
this projects schedule.
Task 1 Project Coordination
Task 1 includes design team coordination and project management, coordination with City/4LEAF
staff, budget and schedule control, including monthly progress reports and invoicing, and quality
assurance/quality control (QA/QC) review of all deliverables.
SRT Deliverables:
• Design team coordination/project management, including monthly invoicing and schedule
and budget reporting throughout the duration of the project
• Meeting notes and agendas for meetings through the construction period
• Engineering support to 4LEAF with CEQA and other permitting activities.
Task 2 Preliminary Design
Task 2 involves gathering, organizing, and reviewing pertinent information related to the project.
This includes existing geotechnical information and information obtained from additional borings
to be performed by 4LEAF. SRT would also review the hydraulic modeling data and validate the
design capacity of the equalization basin, the assumptions made in the 2015 Feasibility Study and
discuss alternative concepts that may benefit the City.

CITY OF PACIFICA //
EQUALIZATION BASIN PROJECT DESIGN SERVICES
Findings and validation of previous work performed by the City and its consultants would be
summarized in a Preliminary Design Report (PDR) and presented to the City/4LEAF for review,
comments and approval prior to commencing with final design. The PDR will discuss means of
construction, construction access, noise and dust control with particular attention to the residents
adjacent to the equalization basin, and restoration and upgrading of the parking lot. Design criteria to
be carried forward into final design would also be documented in the PDR and would include overall
dimensions, material selection, equipment specifications, power requirements, pipeline alignments
and profiles, and preliminary design of the two diversion structures.
Task 2 also includes development of 30-percent drawings, outline of the technical specifications, and
30-percent engineer’s opinion of probable construction cost. SRT assumes the City will supply their
standard front-end documents. This task also includes an internal peer review of the 30-percent
design package including the engineer’s opinion of probable construction cost.
SRT Deliverables:
• Technical Specifications outline
• 30 percent design plans, Engineer’s opinion of probable construction cost
• Internal peer review of all 30-percent design documents
• 30 percent design review meeting with the City/4LEAF

SECTION 2 PROJECT SCHEDULE
The SRT team has developed the proposed project schedule with the goal of completing the
Equalization Basin Project construction by the City’s deadline of June 30, 2018. The proposed
schedule presented on the following page provides an aggressive yet doable design schedule that
SRT is committed to meeting. We have also included the construction substantial completion date
of June 20, 2018.
The schedule is based on the following assumptions:
1. Design start date of December 1, 2015.
2. Availability of the Geotechnical Report from the PM/CM team by January 2016.
3. Availability of environmental mitigation measures to be incorporated into the design documents
by mid-August 2016.
Additionally, to facilitate the PM/CM team and City staff review of all design submittals and solicit
comments, we propose brainstorming/review workshops with the PM/CM team and City staff.
Lastly, SRT plans on continuing advancing the design during the City review periods, aiming to
complete the design by December 1, 2016, thus allowing the PM/CM to bid the project during
the winter months and scheduling the construction contractor bid award by the City Council for
February 2017. This approach would allow the contractor to mobilize in March 2017 and complete
construction to substantial completion within 16 months from the notice to proceed.
The project schedule is attached later in this section.

innovative technologies and practical designs to meet their often tight schedules and budgets.
McMillen Jacobs Associates has extensive experience with analysis, design, and construction of
deep excavation structures in a variety of challenging ground conditions and site constraints. The
collaboration of their structural, civil, and geotechnical engineers gives McMillen Jacobs Associates
a comprehensive understanding of the numerous facets of the design and construction of excavation
support systems.
This cohesive process ensures the designs will be innovative, cost-effective, and constructible.
On many heavy civil construction projects, temporary works design is an essential component in
executing permanent construction. Contractors often must construct temporary structures that
adhere to specific design and safety criteria, and at the same time must be practical and cost effective
to build. McMillen Jacobs’ temporary works support design services include a complete range of
support systems: diaphragm slurry walls, secant pile and tangent pile walls, soil mix walls, soldier
pile walls, sheet pile walls, and liner plate shafts. These can be self-supporting, internally braced, or
tied back configurations. They also provide design services for mechanically stabilized earth, soil
nail walls, rock dowels, anchors, and caissons, and ground freezing.
McMillen Jacobs and SRT staff have collaborated on SFPUC projects.

Characterization to 3.5 bar and through a short section of highly weathered Franciscan
Complex bedrock that can be very hard and abrasive. Because of these
ground conditions, a 15-foot-diameter earth pressure balance tunnel
boring machine (TBM) was utilized for excavation between two deep
slurry diaphragm wall shafts. The TBM was manufactured by Hitachi
Zosen (Hitz) in Osaka, Japan. The tunnel is lined with precast concrete segments followed by steel
pipe as final lining, resulting in an internal finished diameter of 108 inches.
McMillen Jacobs Associates faced numerous design challenges on this project. These included
difficult ground conditions, the proximity of California’s largest active seismic faults (the San Andreas
and the Hayward faults), and the presence of environmentally sensitive
habitats, which required that no intermediate construction shafts be
built. The 58-foot inside diameter, 124-foot-deep Ravenswood launch
shaft is located in Menlo Park and was completed in May 2011. It was
built using diaphragm slurry wall construction methods. The tunnel
was placed into service in 2015. SRT was a subconsultant on this

Caissons constructed in the wet were considered the most feasible construction method for the
shafts. The contractor and its shaft subcontractor proposed the cutter-soil-mixing (CSM) method
for shaft construction. This was the second known application of CSM technology in the U.S. for
construction of a microtunnel shaft, and the first known use for applying shotcrete as secondary
wall reinforcement. Because of the CSM method’s unknown nature, McMillen Jacobs Associates
provided full-time construction monitoring during shaft construction, excavation, and shotcreting.
We also provided full-time observation during the 900-foot microtunnel drive.

Superintendent
831-420-5455, TJCAA staff acted as Project Manager and project electrical engineer
[email protected] for renovation, expansion and improvements to the electrical
cruz.ca.us distribution system at the City’s main Graham Hill WTP. This project
effort was conceived by the City to support future major water quality
process improvements of the existing 24 mgd conventional filtration
plant. Potential improvements included membrane systems, on-site
hypochlorite generation, UV disinfection, ozone generation, and residual handling facilities. The
existing electrical distribution system was originally developed in the 1960s and had reached the end
of its useful life. In addition, it was determined to have insufficient capacity to support the proposed
process improvements. As a result, the WTP’s electrical system required significant renovations
prior to implementing the water quality improvements.
The project included a preliminary design validation report followed by final design. Upgrades to the
electrical system include a new utility 21 kV primary service, new 480 V main-tie-main switchgear
with source transfer logic, remote switchgear operating console for arc-flash considerations, a 1,500
kW standby engine-generator set, and a new electrical building designed to support the subsequent
water quality improvement project. TJCAA was responsible for all electrical and structural elements
of the design, including the medium voltage distribution system and design of a new main electrical
building to house the new switchgear.
TJCAA staff also performed engineering services during construction for the Project for all electrical
and structural design elements. Construction support included a PG&E service coordination,
shop drawing and RFI reviews, and fast
track relocation and redesign of the main
electrical building upon discovery by the
City that the original site was a habitat of the
endangered Mt. Herman June Beetle. This
equipment installed under this Project has

SECTION 5 ADDITIONAL INFORMATION
5.1 Additional Design Considerations
Due to the size of the structure and the anticipated
groundwater cut-off issues, a circular “shaft” type
structure should be considered for the temporary
excavation support and permanent equalization
basin. Excavation support systems utilizing secant
piles, slurry walls, or soil mixing are all viable
options. If slurry walls or secant piles are used, they
could potentially be incorporated into some aspect
of the permanent structure as presented in the 2015
Feasibility Report.
With the location of the shaft near the ocean and the high groundwater table, groundwater cut-
off and flotation would be important design issues for both the temporary excavation support
system and/or for the permanent structure. For the temporary excavation support system control
of groundwater at the base of the excavation can be achieved by either extending the walls of the
shaft to an impervious soil layer or by wells and dewatering, or by a combination of extended walls
and dewatering. For the permanent structure tie-down, ground anchors will need to be used to resist
the flotation force when the equalization basin is empty.
The Equalization Basin Project presents unique challenges due the relatively small area where the
facility will be constructed and the extraordinary depth required to achieve the specified volume.
Although the facility as presented in the 2015 Feasibility Study appears a viable option, other
configurations and construction techniques are available, which could save the City time and money.
An option that could be considered during the preliminary design phase is a pre-stressed concrete
tank. These are commonly designed to be completely buried as shown in the following figures.

[email protected] presence of transient groundwater, and absence of stormdrain facilities in the
650-728-3545 vicinity. Recommended a 50% budget increase and halving the tank capacity.
Reference for: MWSD Alta Vista Maximum tank elevation constraint triggered the partial burial of the tank
Tank No. 2 Project and the use of prestressed concrete as construction material instead of steel as
initially considered. Designed the AWWA D110 tank project and developed
contract documents in conformance with the 60 mitigation measures from the
Steve Leonard Environmental Impact Report and the specific requirements imposed by the
Sewer Authority Mid-Coastside State when lending funds through the Safe Drinking Water State Revolving
General Manager (retired) Fund. Project currently under construction.

650-868-3453 and Bypass Stations, El Granada, CA: Lead engineer for the project pre-
Reference for: SAM Wet Weather design and design. Performed a risk and cost-benefit analysis to compare sewer
Flow Management Project pipe replacement vs. CIPP rehabilitation alternatives for 8,800 feet of a 14-inch-
diameter force main. Recommended a phased implementation approach that
included the CIPP rehabilitation of the most critical 1,500 feet of the sewer pipeline, replacing air release and
vacuum break valves that had severely deteriorated, and further inspecting and evaluating the remaining pipeline
length. Spearheaded the concept of and designed four new temporary bypass connection vaults. Vaults are located
along the remaining 7,300-foot-long section of force main and will provide required redundancy to bypass the
flow while the pipeline is being inspected or repaired in the future. Developed an Operations and Maintenance
Plan for the bypass stations detailing the procurement of the temporary aboveground piping required to connect
successive bypass stations. Co-presented project at NorCal Pipe Users Group 2014 Seminar. The project allowed
the owner to avoid spending $13M.
