MEMORANDUM

TO: Engineering and Operations Committee DATE: May 14, 2021

FROM: Tricia Butler

SUBJECT: Consideration and Action on Award of Construction Contract for Chiquita Water

Reclamation Plant Digester 2 Coating, C-1241U.013

SUMMARY:

Recommendations: 1) Authorize awarding a construction contract to Murphy Industrial

Coating, Inc. for the Chiquita Water Reclamation Plant Digester 2 Coating Project in the amount

of $296,444.

Issue: The District has completed the design and bid process for the CWRP Digester 2 Interior

Coating/Rehabilitation planned Capital Repair and Replacement project. This agenda item

recommends award of the construction contract to complete the work.

Fiscal Impact: The recommended contractor bid is $296,444 for the Scope of Work. The total

project cost estimate is $400,000 and includes other project-related costs. This project was

budgeted in the Capital Replacement Program for $400,000 as project CHIQT2204C for

completion in FY2021- FY2022. The District will use a portion of the proceeds from the 2020A

Revenue Bonds to fund the project.

Previously Related Action: The Board approved the CRP budget in May 2020.

Adherence to Policy: The Digester 2 Interior Coating/Rehabilitation work is consistent with the

District’s Business Plan Goal “To Provide Quality, Uninterrupted Service,” and the Core

Objective Category “Water Quality Standards and All Environmental Compliancy Goals are Met

or Exceeded Continuously.” This facility is an essential treatment process to meet regulatory

requirements for the reuse/disposal of sludge generated at the Chiquita WRP.

Anticipated Board Action: This item is anticipated to be brought to the Board of Directors

meeting on June 2, 2021 for consideration as a Consent Calendar item.

DISCUSSION:

The digesters at the CWRP process sludge

produced in the wastewater treatment process.

Digester 2 (see Figure 1) was constructed with

Phase 1 of the treatment plant around 1986.

Harper and Associates completed a condition

assessment to determine the scope of work

required to rehabilitate the interior coating and

other appurtenant equipment. The required

scope is primarily coating removal and

replacement on the inside of the tank. Current

conditions are shown in Figure 2.

The project was advertised for bids on Monday, April 5, 2021 to six contractors pre-selected by

the District. Three potential bidders attended the mandatory pre-bid meeting. National Coating &

Lining contacted the District on the day of the bid to advise that they would not be bidding the

project.

The bids were received and opened on April 30. Murphy Industrial Coating and Lining Co.

(Murphy) Inc. submitted a bid of $296,444 along with the required bid documents and is

considered a responsible bidder. The Engineer’s Estimate for the project was $300,000. A

summary of bids is provided in Table 1.

MEMORANDUM


FROM: Jeff McDonnell, Don Bunts

SUBJECT: Consideration and Action on Project Acceptance for Construction of Secondary

Clarifier No. 3 at the Chiquita Water Reclamation Plant (CWRP) for the

Secondary Treatment Expansion, Contract C-1241T.012E

SUMMARY:

Recommendation: Accept the work performed by Kingmen Construction, Inc. (KCI) for the

CWRP Secondary Clarifier No. 3 project, C-1241T.012E, file Notice of Completion (NOC), and

release retention no later than 60 days after the Notice of Completion has been filed, provided no

claims have been filed with the District and that the Punch List items have been completed.

Issue: All work on this project has been completed satisfactorily and it is ready for acceptance

by the District.

Fiscal Impact: The proposed CWRP Secondary Treatment Upgrades estimated cost is

$17.8 million. The overall project funding is split between the District ($6.2 million) and new

development ($11.6 million). The new development funding will be RMV’s responsibility in

accordance with a Reimbursement Agreement (under development). The agreement proposes to

have the District fund the project to meet its timeline and be reimbursed, including interest, from

future development bond funds.

Previously Related Action: At the SMWD 2020 Annual Strategic Planning Workshop held

February 21st, the Board supported the CWRP Secondary Treatment Upgrades as a “Need to Do

Project.” On April 17, 2020, the Board approved the pre-purchase of the Clarifier No. 3 Sludge

Collector System from Ovivo USA, LLC. On June 19, 2020, the Board awarded the

construction contract to KCI for the amount of $3,315,457.

Adherence to Policy: Construction of the work adheres to the SMWD Design Criteria and

Standard Drawings for Water and Sewer Facilities.

Packet Pg. 6

DISCUSSION:

Increased flow capacity and redundancy was required in the secondary treatment process at

CWRP to address the needs of the District and to accommodate the increase in flows associated

with the build out of Rancho Mission Viejo (RMV). As part of the odor control project the

trickling filters were removed from the treatment process. This has required all of the flow to be

put through the existing two aeration basins and their associated two secondary clarifiers.

While the plant was capable of handling the flows, there was no redundancy with either process

in the case of equipment failure or scheduled outages required for maintenance. With the

construction of Secondary Clarifier No. 3, to be followed with the addition of two new Aeration

Basins No. 3 & 4, the necessary redundancy will be achieved. In addition, these two construction

projects will fulfill the additional treatment capacity to support the future growth.

Construction on this project has progressed and completed smoothly with very few

complications. The pre-purchase of the Secondary Clarifier No. 3 Sludge Collector System and

Return Activated Sludge (RAS) Pump No. 3 was successfully completed by the District and

made available to the Contractor for installations before the construction sequence required it.

The Contingency bid item on this project was chiefly used to construct the Return Activated

Sludge (RAS) No. 3 Pump Station that was not included in the original project design but

necessary for the full operation of Secondary Clarifier No. 3. The District began Beneficial Use

of the Clarifier and its appurtenances and commissioned it starting on 08APR21.

Upon the commissioning of new Secondary Clarifier No. 3, existing Secondary Clarifier No. 4

has been taken out of service and inspected for necessary maintenance and repairs. It is

anticipated that a project to refurbish existing Clarifier No. 4 will be implemented in the near

future.

The photo in Figure 1 below provides an overview of the new Clarifier No. 3 System as

construction was nearing completion in mid-March 2021. Existing Clarifier No. 4 is shown in

the background.

Funding for the secondary clarifier portion of the work is proportionally split between District’s

requirement for redundancy which is funded through the Esencia CFD (~33.3 percent) and

requirements for expansion to meet new development projections (66.7 percent). The new

development funding will be RMV’s responsibility in accordance with a reimbursement

agreement (under development). The agreement proposes to have the District fund the project to

meet its timeline and be reimbursed with interest from future development bond funds.

Project funding for the secondary expansion was tracked under MUNIS code CHIQT1402C.

MEMORANDUM


FROM: Jeff McDonnell, Don Bunts

SUBJECT: Consideration and Action on Addenda for Butier Engineering, Inc., and GMU

Geotechnical, Inc. for the Trampas Canyon Dam & Reservoir, Contract No. C-

1773

SUMMARY:

Recommendation: 1) Approve Addendum No. 3 for Butier Engineering, Inc. (BEI) in the

amount of $94,800 for construction management services on The Trampas Reservoir Project;

2) Ratify Addendum No. 4 for GMU Geotechnical, Inc. (GMU) in the amount of $49,632.50 for

geotechnical services on the Trampas Reservoir project.

Issue: Additional funds are needed for construction support consultants for construction

management and geotechnical services. These additional costs have been necessitated by the

extension of the project beyond December 2020, the need for assistance in inspections associated

with filling of the Trampas Dam, and the complexity of solving the problems with regard to the

West Saddle Dam and Piezometer Systems.

Fiscal Impact: Funding of the primary project will be from a $15 million State Water

Resources Control Board Grant, a $96 million 1% Interest Loan, new development funding,

potential partners, Rancho Mission Viejo (RMV), and District New Capital Project Reserves.

Previously Related Action: The Board awarded contract Addendum No. 2 to BEI on

06NOV19, and Addendum No. 3 to GMU on 05AUG20.

Adherence to Policy: This project helps meet the District’s goal of recycling 100% of its

wastewater and reduces demands on the imported domestic water system.

DISCUSSION:

BEI Additional Costs for the Reservoir/Dam:

Completion of the remaining work and Punch List items by Sukut, and review of miscellaneous

change order requests continued through 2020 and remains ongoing. Based on all information

available, the District recommends that BEI stay engaged on the project in a detailed fashion, but

on a part-time basis until the end of June 2021. After that time, assistance by BEI should be

more sporadic and minimal in nature. Butier’s last contract addendum was issued in November

of 2019 and assumed project completion in December 2020.

The District is taking more aggressive steps in concluding the change order negotiation process

with Sukut, and expects that all remaining issues, and positions on those issues to be fully

disclosed and agreed upon by approximately the end of May 2021. This would allow for the

greatest portion of the final processing of change orders and job closeout proceedings to happen

in June 2021.

As an expansion to the services provided by BEI, they are currently offering assistance in the

daily inspection of the Dam while it is being filled. This inspection and reporting process of the

Dam is required by DSOD as a condition of the Permit to Operate. This activity is a two-person

operation, requiring approximately 6 manhours per day during the normal work week, and

10 manhours per day on weekends and holidays. This requirement will remain in effect until the

Dam is completely filled, or until DSOD deems that such inspections can be reduced or

otherwise adjusted. BEI is currently providing one Inspector to assist during the week and

compiling the report documents to provide to DSOD monthly. The District Inspectors are

covering all other work shifts on this item. This activity will be monitored and re-evaluated at

the end of June 2021 to consider any needed staffing changes to promote further efficiencies.

BEI has provided a proposal for this supplemental work which has been included in attached

Exhibit A. Below is the summary cost from that proposal and a Contract Summary.

BEI Addendum No. 3 Summary:

Final Inspections, Reporting and Contract Closeout Services in 2021: $ 55,830

Additional Services by GMU Geotechnical:

The largest portions of the additional contributions made by GMU during the latter stages of the

Work consisted of two of the larger technical problems experienced on the whole project:

• Structural Integrity of the West Saddle Dam Cut Off Wall.

• Successful Construction and Operation of the Piezometer Level Measuring System.

The West Saddle Dam portion of the project differs in design as compared to the Main Dam and

the East Saddle Dam in that the core involves the use of an integral cut off wall comprised of a

special lightweight concrete (slurry) that would prevent any leakage at all from passing through

the body of the West Dam. For the Main Dam and the East Dam, engineered layers of special

sands and gravels allow for a very small amount of leakage to pass through those massive

structures in a measurable and controllable fashion that can be monitored, and do not have a cut

off wall.

When the West Dam Cut Off wall was originally placed in the field, samples of the slurry used

were taken for laboratory testing. When all the laboratory testing was completed, and the reports

provided, it was recognized that one-third of the structure showed failing results. A red flag was

raised and several weeks ensued wherein the District, all the consultants, and DSOD worked to

find a solution. Ultimately a complex procedure was developed to core drill and extract

specimens from the wall that was in place, and to test those specimens. Fortunately, those

specimens tested with favorable results, and it could be concluded that the original samples were

flawed and could be ignored. The cut off wall will therefore not have to be demolished and

reconstructed. GMU played a very large part in developing the remedial procedures and did a

large part of the laboratory testing and reporting involved.

The Piezometer Level Measuring System problems were among the largest challenges on the

project. This system involves eleven wells with level measuring instruments installed within

them at various locations on the Main Dam and East Dam embankments. The instruments

measure water levels in the dam to assure they are within safe engineered limits required in the

project design.

In synopsis, five of the eleven Piezometer wells that were installed required reconstruction.

Three have been determined to be the responsibility of the District, and two are the responsibility

of the Contractor. This is a large subject of change order negotiations with the Contractor at this

time.

It took many months for DSOD to agree to a proper procedure for the reconstruction. Once

DSOD agreed to such procedures, it was time consuming and costly to construct and implement

them. Subsequently, DSOD was very involved in reviewing the validity of the data that was

being produced by the System resulting in many weeks of investigating, reporting, and

conferencing. Ultimately, the data was verified to be compliant with the design requirements

and the System was allowed to be commissioned. GMU’s contribution to developing the work

2.3

Packet Pg. 12

procedures, and sampling and analysis of the water level data was a major component in

achieving success on the Piezometer Level Measuring System.

Both of the above issues were immensely important to DSOD. All revised work procedures and

the resulting data produced was subject to the review and approval of DSOD.

Please see attached Exhibit B provided by GMU proposing a budget increase of $49,632.50 for

geotechnical services to assist in resolving the above challenges.

Mr. Jeff McDonnell, P.E.Santa Margarita Water District26111 Antonio ParkwayRancho Santa Margarita, CA 92688

Subject: Amendment No. 3 Construction Management Services for the Trampas Canyon Dam and Reservoir.

SMWD: Project No. C-1773 SMWD: PO No. 360974

Dear Mr. McDonnell:

The Butier Team was engaged June 30, 2017 to perform Construction Management and Inspection services for the above referenced project. Purchase Order 360974 was received in early July 2017 and NTP was issued concurrently. Amendment No.1 was executed on December 13, 2017 for $373,685. Amendment No. 2 was executed on November 15, 2019 for $1,313,276.

Since the issuance of Amendment No.2, the contract period of performance has increased by approximately 7 months based on actual completion dates of critical path activities. Approximately three (3) months of additional Contract duration is directly tied to weather related impact. The remaining construction duration can be attributed to various Contractor imposed and supplier delays. It is believed that several concurrent delays occurred beyond the approximate 3 additional months of weather delays, however since the last official project schedule update was provided in May 2020, there is no clear explanation of additional time supported by the Contractor’s CPM schedule.

Due to staff adjustments related to the construction management of the Trampas Recycled Water Pump Station, a significant amount of budget was spared and available for use for the remaining Trampas onsite staff. Additionally, the inspection and management staff were diligent in conserving budgeted hours where possible to assist in overall cost efficiency. This allowed the current budget to extend further than originally anticipated and is the reason why this additional request has been minimized.

The rate structure associated with this request is as follows and mirrors the structure already in place:

Resident Engineer: $170 per hour

Field Construction Manager: $145 per hour

Technical Support/Document Control: $105 per hour

We are requesting and additional $ 94,800.00 with justification as follows:

Tasks listed below are numbered in accordance with the fee schedule provided as a part of this request:

Task 2- Project Management/ Administration (Butier Engineering): Support for Reservoir Filling Efforts: SMWD requests that Butier provide initial inspection services during the first 2 months of reservoir filling to ensure compliance with the DSOD approved fill plan. This effort allows SMWD personnel to become familiar with the site and the inspections necessary during the fill stage of the reservoir. For safety reasons, there will always be two (2) people required onsite during the inspections. The hours illustrated below constitute the labor effort necessary to provide first fill inspections in accordance with DSOD and AECOM guidelines as well as training for SMWD personnel for efforts moving forward. An additional 250 hours were added for Field Construction Manager (Inspector) to provide the necessary fill inspections for approximately 3 months if needed. An additional 16 hours were added for the Resident Engineer in the event coverage in place of the Field Construction Manager is needed.

Change Request:

Field Construction Manager: 250 @ $145.00: $36,250

Resident Engineer: 16 Hours @ $170.00: $ 2,720

Mr. Jeff McDonnell


26111 Antonio Parkway

Rancho Santa Margarita, CA 92688 GMU Project No. 18-001-10

Subject: Request for Budget Increase, Geotechnical and Materials Testing

Services for Construction of the SMWD Trampas Canyon Dam

and Reservoir, Orange County, California

References: Our “Supplemental Proposal for Geotechnical and Materials Testing

Services for Construction of the SMWD Trampas Canyon Dam and

Reservoir . . . . ,” dated June 18, 2020 (GMU Project 18-001-10)

Dear Mr. McDonnell:

GMU is submitting this proposed budget increase for the construction support services for the

Trampas Canyon Dam and Reservoir (Trampas Dam) project.

GMU’s remaining contract amount is currently at $1,442.50. GMU’s January invoice only

included partial services complete during the month of January. Our costs for the additional

services completed during January 2021 and through the 1st week of February (i.e., January 2021

through February 5, 2021) amounted to $20,550.00, which results in a net amount of $19,107.50

we are currently holding for billing.

GMU’s request for a budget increase is needed due to performing work outside our scope of

work and associated costs outlined in our referenced supplemental proposal for the project.

OUT OF SCOPE SERVICES COMPLETED THROUGH FEBRUARY 5, 2021

The out-of-scope services GMU performed through February 5, 2021 and associated costs are as

follows:

• West Saddle Dam (WSD) Cutoff Trench. Samples collected on July 1, 2020 (Day 3 of

construction) were tested and yielded inadequate strength and hydraulic conductivity tests

results. In order to complete the access road grading and to provide data to support

conformance to the project specifications, the contractor was required to obtain additional

samples for project conformance testing. This additional coring effort was performed in

2 days as described below:

o August 8, 2020 to obtain samples from the top of the trench to determine if the fill

could be placed above the cutoff trench to complete the access road grading.

o December 22, 2020 to obtain a continuous core through the cutoff trench to

collect samples for lab testing.

EXHIBIT B

Mr. Jeff McDonnell, SANTA MARGARITA WATER DISTRICT

Request for Budget Increase: Geotechnical and Materials Testing Services for Construction of

SMWD Trampas Canyon Dam and Reservoir

February 12, 2021 2 GMU Project 18-001-10

Our field services and laboratory testing associated with the WSD coring efforts (i.e.,

field and lab testing) along with the project meetings, discussions and review of proposed

drilling and sampling methods we were requested to participate in amounted to $10,289.

• Main Dam Piezometers: Installation of four (4) new piezometers, decommissioning of

one and repair of another at the Main Dam was required for the project due to the

following:

o water levels being measured in existing piezometers (OS-4 an OS-5) where water

was not anticipated

o an obstruction in one of the piezometers (OS-3)

o one piezometer (OS-1) needing to be redrilled due to original design resulting in a

depth that drilled through the top of the drainage blanket (i.e., piezometers within

the shell embankment were to have a tip elevation above the drainage system).

o repair of a piezometer (OS-8), which had a separation in the pipe at about 7 feet

below grade

The services associated with the above installation, decommissioning, and repair were

accounted for in our referenced supplemental proposal. However, the services outlined

below were not included in our of scope of work.

o Prior to drilling of the new piezometers, GMU was requested to bail piezometers

OS-4 and OS-5 and perform a video survey of the 8 piezometers (OS-1 through

OS-8) located within the Main Dam shell embankment. Due to the small

diameter pipe (i.e., 1¼” I.D.) a special camera was required.

GMU contracted with a video survey company to provide the necessary services. The

costs associated with these services amounted to $7,524 of which $6,200 was paid

directly by GMU to video survey company.

o After the drilling of the new piezometers, water levels were noted in new

piezometers. GMU was requested to provide the following additional services

between November 9, 2020 through February 5, 2021.

o The piezometer services included multiple site visits to take measurements and

bail the piezometers, download and interpret transducers placed in 3 of the

piezometers for AECOM’s evaluation, prepare summary tables and graphs for

AECOM and BEI following each of our site visits, and participate in discussions

and meetings with AECOM, BEI and DOSD.

The costs of the additional services related to the measuring, bailing, downloading and

interpretation of transducer data, preparation of the summary tables and graphs, and

participation in discussions and meetings related to the piezometers amounted to $28,681.

Miscellaneous Items Related to Access Road, WSD Riprap, and Punch List Items:

o GMU’s field technician was required to spend additional hours at the project due

to the following:

▪ Re-working of the access road subgrade soils at the ESD cul-de-sac area due

to wet soils the contractor tried to compact without allowing them to dry out.

This additional work occurred on a Saturday and resulted in overtime costs.

▪ Geotechnical oversight during removal of the contractor’s ingress/ egress

ramps to the reservoir bottom.

▪ Placement of bedding materials and rip rap materials on the WSD slope face

after removal of a contractor’s access ramp.

These miscellaneous tasks, which amounted to ~50 hours of engineering technician and

~6 hours of geologist time, were absorbed in the hours allocated for the project and

therefore, no additional costs were realized.

The out-of-scope tasks, as related to the WSD cutoff trench the Main Dam piezometers,

amounted to a total of $46,494.

TASKS/COSTS REMAINING TO COMPLETE

Based on discussions with yourself, BEI, and AECOM, regarding our as-built project reports and

our involvement with initial portion of the project Fill Up Plan prepared by AECOM (i.e., 10 site

visits to manually measure piezometers prior to and during initial filling of the reservoir and

office services needed to compile and send out the data to the project team), we anticipate the

following costs are needed to close out the construction and initial fill up phase of the project:

• Amount Remaining in Contract: ($ 1,442.50)

• Amount not billed through February 5, 2021: $ 20,550.00

• Piezometer Readings and Reporting

(assumes 40 hours field and 15 hours office services): $ 8,025.00

• Reports (Non DSOD Facilities submitted week of February 8, 2021,

(DSOD Facilities report scheduled for March 31, 2021) $ 22,500.00

TOTAL COSTS REQUESTED TO COMPLETE REMAINING TASKS: $49,632.50

MEMORANDUM


FROM: Daniel Peterson

SUBJECT: Consideration and Action on Purchase of Camera Video Inspection Van

SUMMARY:

Recommendation: Authorize purchase of camera video inspection van from Plumbers Depot

Inc for $243,500.

Issue: In order to accommodate the maintenance of an additional 125+ miles of wastewater

pipeline as part of the City of San Juan Capistrano annexation, the District needs to add an

additional camera video inspection van.

Fiscal Impact: The proposed vehicle is included in the FY2022 Capital Expenses budget for

San Juan Capistrano. Due to the long lead time to produce this vehicle, this item is being

brought to the Board ahead of time.

Previously Related Action: The District authorized the execution of the Annexation Agreement

with the City of San Juan Capistrano on January 17, 2020.

Adherence to Policy: This project is consistent with the District’s mission to “Provide a high

level of service with maximum cost effectiveness.”

Anticipated Board Action: This item is anticipated to be brought the Board of Directors

meeting on May 21, 2021 for consideration as an Action Item Recommended by Committee.

DISCUSSION:

The District’s Collections crew is responsible for maintaining more than 630 miles of wastewater

pipeline. As part of these maintenance practices, sewer lines are inspected utilizing a specialized

vehicle that can send a remote-controlled camera into the sewer line and take live video of the

condition of the pipeline. This information can be invaluable in identifying potential blockages,

debris, or other hazards within the pipeline.

3.1

Packet Pg. 22

As part of the acquisition of the City of San Juan Capistrano’s water and wastewater systems, the

District’s wastewater system will increase by 20%. In order to accommodate the addition of this

mileage, the District budgeted for the addition of 3 pieces of heavy equipment: a combination

unit, a jetter, and a CCTV truck. The City currently utilizes contract services for video inspection

services that costs $0.72 per linear foot. The District estimates that it’s cost to perform the same

work is approximately $0.62 per linear foot.

There are three primary vendors who provide the hardware necessary for video inspections:

Cues, Aries, and Envirosight. The District currently operates one video inspection truck that

utilizes the Cues hardware. The camera and video hardware are proprietary and will not work

with other vendors hardware. Because of this, staff recommendation is to sole source this

purchase and procure the new vehicle that uses the Cues hardware. Rather than have two

different types of video inspection hardware and software that would not work with each other,

having both units be the same hardware will reduce downtime and maintenance issues.

budgeted in the Capital Replacement Program for $500,000 as project CHIQT2500C for

completion in FY2021- FY2022. The District will use a portion of the proceeds from the 2020A

Revenue Bonds to fund the project.

Previously Related Action: The Board approved the CRP budget in May 2020.

Adherence to Policy: The Force Main Replacement Project is consistent with the District’s

Business Plan Goal “To Provide Quality, Uninterrupted Service,” and the Core Objective

Category “Water Quality Standards and All Environmental Compliancy Goals are Met or

Exceeded Continuously.”


meeting on May 21, 2021 for consideration as an Action Item Recommended by Committee.

Packet Pg. 24

DISCUSSION:

In 2014, the Chiquita Water Reclamation Plant

Influent Lift Station “Phase 3 Pump Station” Force

Main experienced a failure requiring an emergency

sewage bypass and pipe repair. The pipe manifold

immediately downstream of the pumps, as shown in

Figure 1, was eroded through and was replaced in

2014. The District planned to replace the remaining

downstream pipeline once the screening facility

design concepts and site improvements were

developed in conjunction with the concepts for

added redundancy and flexibility for pipeline

inspection and maintenance.

This current project replaces approximately 160 feet of 36-inch diameter pipe, along with

valving and provisions for new connections to the forthcoming upgrades of the original influent

lift station.

The project was advertised for bids on April 14, 2021 to three contractors pre-selected by the

District. Three potential bidders and two bypass pump sub-contractors attended the mandatory

pre-bid meeting. The bids were received and opened on May 5, 2021. Kingmen Construction

submitted a bid of $622,900 along with the required bid documents and is considered a

responsible bidder. A summary of bids is provided in Table 1.

Packet Pg. 25

The Engineer’s Estimate for the project was $500,000. All three bids received were higher than

the engineer’s estimate, and the low bid was approximately 23 percent lower than the next

higher bid.

During the bid period, questions and feedback from the bypass pump supply companies resulted

in the addition of inclusion of operational costs for three days of bypass pumping, and a flanged

connection to the bypass pump system that will also facilitate the future rehabilitation of the

existing original influent lift station pump station. These costs account for an estimated $50,000

of the bid cost that was not included in the engineer’s estimate.

The most significant difference between the engineer’s estimate and the bids is the cost of the

provision and installation of the 36-inch pipe. The engineer’s estimate assumed a unit cost of

approximately $1,000 per foot. This unit cost is higher than the unit cost of other project actual

unit costs for this size of pipeline in this geographical area. However, this project is unique with

160 feet of pipe as compared to typical projects with thousands of feet of pipe. The 36-inch

diameter size is larger than a size pipe that would typically be stocked by pipe suppliers. The

cost of setting up for production of a limited length of pipe drives up the unit cost of the pipe.

The current market setting is that construction materials are in limited supply and the

construction industry is in high demand. These factors contributed to the actual bids being higher

than the estimated cost.

Kingmen’s bid was lower than the other bids by a significant margin. Kingmen is mobilized and

working currently on the Aeration Basin construction project at the Chiquita Water Reclamation

Plant, providing economies in the mobilization for this project. Kingmen also realized some

savings in their approach to the pipeline provision and construction, as well as the bypass

pumping.

Staff recommends award of the construction contract to Kingmen Construction in the amount of

$ 622,900.

Recycled water production from the Chiquita Water Reclamation Plant and Oso Water Reclamation

Plant are presented in the following tables. Increase in production in April was due in part from higher

demands associated with warmer days, but primarily because any surplus flow is sent to Trampas and

not through the outfall for ocean disposal.

Packet Pg. 39

Notable Events in April 2021

Allen-McColloch Pipeline shutdown

• The Allen-McColloch Pipeline (AMP) shutdown was

scheduled from April 4 – May 10, 2021.

o The shutdown was required in order to reline a

section of the prestressed concrete cylinder pipe.

o Picture #1 shows the contractor installing the

steel liners within the pipe.

• The AMP line is typically responsible for supplying

60% of the SMWD water supply.

o The District worked with regional partners to

wheel water throughout the region to ensure that

all agencies maintained water deliveries.

• The shutdown finished early, and the pipeline was returned to service on 5/4/2021.

Cypress Point RW Main Break

• On Saturday, 4/24 crews received a call around 8 pm indicating a large geyser of water erupting near

the Cypress Point community located south of Lake Mission Viejo.

o Crews discovered that the 16” recycled line was causing the geyser. The recycled system was

shut down and crews begin to clean the dirt and debris from the streets.

▪ Pictures #2 and #3 show the debris caused by the leak as well as the damage caused.

o The repair was made on Monday and Tuesday and the line was back in service on

Wednesday. Picture #4 shows the concrete pad being prepared after the repair.

o All regulatory agencies were informed of the Non-Domestic break.

o Preliminary analysis shows that the pipe failed due to internal corrosion.

North Beach LS – Install Motor Control Center

• The Electrical Division completed work on upgrading the motor control center at North Beach Lift

Station.

• Picture #5 shows the before while Picture #6 shows the after of the cabinet work.

Chiquita WRP – Replaced pumps in

primary building

• The Mechanical Division

completed the installation of new

Sepex progressive pumps in the

primary building.

• The existing diaphragm pumps

were at the end of useful life and

parts were no longer available.

• Picture #7 shows the before

while Picture #8 shows the after.

AB 1826 Compliance

• AB 1826 requires business to recycle their organic waste.

• Staff worked with its landscaping company to achieve AB 1826 compliance ahead of schedule.

Emergency Communication Improvements

• The Safety Division completed the registration of several key staff in enrollment into the

Government Emergency Telecommunicaiton Service (GETS) system.

o By enrolling into the GETS service, District staff is eligible to participate in the Wireless

Priority Service which allows prioritized cellular usage during times of congested network

traffic such as a natural or manmade disasters.

o The system utilizes a calling-card which allows District staff to be prioritized on cellular

networks during emergency periods.

o This is one of several elements the District has in place to ensure communication in an

emergency.

Operations and Maintenance Activities

Collections Division

• Cleaned 148,610 feet of sewer pipeline.

o Picture #9 shows crews cleaning Marguerite Parkway with the

appropriate traffic delineation.

• CCTV inspected 25,670 feet of sewer pipeline.

• Performed 65,925 feet of preventative maintenance work orders.

• Maintained 10 lift station wet wells

Valve & Hydrant Division

• Reduced valve turning activities during AMP shutdown and focused on hydrant maintenance.

o Painted 328 fire hydrants

o Pictures #10 and #11 show the before/after of a hydrant which was discovered to be

completely overgrown. Staff worked with the property owner to ensure that the hydrant will

remain uncovered moving forward.

Safety Division

• Coordinated replacement of access gate at Cordova Lift

Station seen in Picture #12.

o The existing gate was due for replacement and the

Safety Division identified an opportunity to

replace the gate with an ergonomic improvement

which reduces the risk of back injury.

o The existing gate was a single panel which

required great effort to move. The new gate is a

dual-panel design which makes it easier for staff

to open/close.

• Enrolled several key District staff in NIMS/SEMS

training.

o This training is vital in training staff how to utilize the Incident Command System protocol.

o Completion of this training allows the District to remain eligible for disaster relief funds.

• Provided training on:

o CPR/First Aid/AED

o Water Industry Distribution Operation Safety

o HAZ-WOPER (WWTP Operators)

o Advanced Construction Safety

o New Hire Safety Orientation

o ARC Flash Safety
