SUBJECT:Approval to Increase the CIP P2561 Budget in an Amount of $150,000 and approval of Change Order No. 1 in an amount not-to-exceed $105,535.48 to the Construction Contract with Layfield USA Corporation for the Reservoir 711-3 Floating Cover and Liner Replacement Project
GENERAL MANAGER’S RECOMMENDATION:
That the Otay Water District (District) Board of Directors (Board): 1. Increase the budget for CIP P2561 by $150,000 (increase the CIP
budget for P2561 from $2,300,000 to $2,450,000); and2. Approve Change Order No. 1 to the existing constructioncontract with Layfield USA Corporation (Layfield) in an amountnot-to-exceed $105,535.48 for the Reservoir 711-3 FloatingCover and Liner Replacement Project (see Exhibit A for Project
location).
COMMITTEE ACTION:
Please see Attachment A.
PURPOSE:
To obtain Board authorization to increase the CIP P2561 budget in the amount of $150,000 from $2,300,000 to $2,450,000 and to obtain Board
authorization for the General Manager to execute Change Order No. 1 in an amount not-to-exceed $105,535.48 to the construction contract
with Layfield for the Reservoir 711-3 Floating Cover and Liner Replacement Project (Project).
AGENDA ITEM 3
2
ANALYSIS:
The 16 million gallon 711-3 Reservoir was originally constructed with its existing reinforced polypropylene (RPP) floating cover and liner
in 2002. In the last few years, the floating cover has been repeatedly repaired to maintain the integrity of the cover material.
Dive videos taken showed leaks and sunlight penetrating the floating cover in many places. It was no longer cost effective to continue to repair the existing cover that has reached the end of its life
expectancy.
The Project scope of work generally consists of the removal and replacement of the existing reservoir liner and floating cover with a new reinforced chlorosulfonated polyethylene (CSPE) liner and
floating cover. The CSPE geomembrane will have a 30 year warranty. The warranty will not be prorated for the first 15 years, and then
prorated for years 16 through 30. The floating cover work is very specialized and requires that the installation be performed by contractors that are certified to install the CSPE material, which is supplied by Burke Environmental Products.
At the July 11, 2018 Board meeting, the Board awarded a construction contract in the amount of $1,997,000.40 to Layfield. A Notice to Proceed was issued on August 1, 2018. Change Order No. 1 (Exhibit B), which is the subject of this staff
report, serves to close out the construction contract and includes the following items associated with the 711-3 Reservoir cover and liner installation project:
• Addition of five (5) calendar days for use of Bid Item 8 –
Reservoir Improvement Allowance associated with cathodic repair work.
• Addition of two (2) calendar days for use of Bid Item 8 –
Reservoir Improvement Allowance associated with the construction of additional anchor bolts.
• Reconciliation of unused portion of Bid Item 8 – Reservoir Improvement Allowance.
• Owner directed slope repair acceleration costs and additional
time (151 calendar days) associated with work resequencing and production impacts as part of post weather cumulative impacts.
• Costs and time (81 calendar days) associated with contractor efforts to identify and temporarily repair a water leak in an existing concrete structure.
• Reimbursement of lost water at the 711-3 Reservoir resulting from failed bacteriological and VOC testing.
3
• Reimbursement for liquidated damages from November 12, 2019 until Substantial Completion on November 27, 2019.
• Addition of eighteen (18) calendar days due to weather impacts
per Contract Specifications. In total, the cost associated with the items in Change Order No. 1 is
$105,535.48. Time impacts associated with this change are also provided in Exhibit B. The two hundred and fifty-seven (257)
additional days added to the contract will result in a revised total contract duration of 469 calendar days. As of November 27, 2019, the Project was substantially complete and the 711-3 Reservoir has been returned to service.
FISCAL IMPACT: Joe Beachem, Chief Financial Officer The total budget for CIP P2651, as approved in the FY 2020 budget, is $2,300,000. Total expenditures, plus outstanding commitments and
forecast including this contract, are $2,448,670. See Attachment B for budget detail.
Based on a review of the financial budget, the Project Manager anticipates that with a budget increase of $150,000, the Project will
be completed within the new budget amount of $2,450,000. The Finance Department has determined that, under the current rate model, 100% of the funding will be available from the Replacement Fund.
GRANTS/LOANS:
Engineering staff researched and explored grants and loans and found none available for this Project.
STRATEGIC GOAL:
This Project supports the District’s Mission statement, “To provide exceptional water and wastewater service to its customers, and to
manage District resources in a transparent and fiscally responsive manner” and the General Manager’s Vision, "To be a model water agency
by providing stellar service, achieving measurable results, and continuously improving operational practices."

Reason:
Item No. 1:
The Contract Bid Item No. 8, Reservoir Improvement Modification Allowance, was utilized to account for additional cathodic
repairs. Costs were accounted via the Contractual Allowance; however, it was agreed that the added scope resulted in a 5 (five)
calendar day extension to the Contract. This change is necessary to provide the time extension agreed upon to resolve all costs
associated with this issue.
Contract / P.O. Change Order No. 1 page 3 of 3
Item No. 2:
The Contract Bid Item No. 8, Reservoir Improvement Modification Allowance, was utilized to account for additional tension tower
anchor bolts. Costs were accounted via the Contractual Allowance; however, it was agreed that the added scope resulted in a
2 (two) calendar day extension to the Contract. This change is necessary to provide the time extension agreed upon to resolve
all costs associated with this issue.
Item No. 3:
The Contract Bid Item No. 8, Reservoir Improvement Allowance, was used to the maximum extent practical and is no longer
required.
Item No. 4:
In late December 2018 the District directed weekend work to implement reservoir slope repairs prior to an impending storm. The
Contractor also asserted cumulative weather impact costs and time associated with weather conditions during the course of
construction. This change order is necessary to implement the modification and resolve all costs and time associated with Owner
directed acceleration and cumulative weather time impacts for contractor implemented work resequencing and production
impacts.
Item No. 5:
Subsequent to filling the reservoir for water quality testing a leak was revealed by water emanating from the reservoir underdrain
system. As this water flow was not present prior to commencement of construction activities the Contractor was directed to
locate and repair the source of the leak. The Contractor performed manned diver entry, visual inspection after draining the
reservoir, pressurized smoke testing of the underdrain system ultimately locating the leak with a second diver entry. The source
of the leak was determined to be a system of cracks in an existing concrete structure at the floor of the reservoir which was an
existing reservoir element to be reused as part of the Contractor’s scope. This change order is necessary to implement the
modification and resolve all cost and time impacts with this issue.
Item No. 6:
Resulting from failed bacteriological and VOC testing on the 711-3 Reservoir, draining of the reservoir was required. This change
order is necessary to allow the District to recover the additional expenditures incurred for lost water pursuant to contractual
provisions.
Item No. 7:
Pursuant to contractual provisions, failure of the Contractor to complete the work within the time allowed will result in damages
being sustained by the District for each calendar day the Contractor fails to substantially complete all work. The adjusted
Contract completion date was November 12, 2019 and substantial completion was achieved on November 27, 2019 resulting in
15 days of liquidated damages. This change order is required to reimburse the District for costs associated with the Contractor
not completing the project within the allotted time.
Item No. 8:
Contract Documents Section 00700-8.5 provides for no cost time extensions due to weather impacts on the project progress.
Weather impacted the project eight (18) days between December 1, 2018 and May 31, 2019. The project was impacted on
December 6, 7 and 31, 2018, January 5, 6, 14, 15, 16, 17, 18, and 31, February 2, 4, 5 and 14, May 1, 9 and 10, 2019 due to

$1,880.00 to the Construction Contract with Cass Arrieta for the Vista Vereda (CIP P2574) and Hidden Mesa Road (CIP P2625) Water Line Replacement Project
GENERAL MANAGER’S RECOMMENDATION:
That the Otay Water District (District) Board of Directors (Board)
approve Change Order No. 4 to the existing construction contract with Cass Construction, Inc. dba Cass Arrieta (Cass Arrieta) in an amount not-to-exceed $1,880.00 for the Vista Vereda and Hidden Mesa Road Water Line Replacement Project (see Exhibit A for Project location).
COMMITTEE ACTION:
Please see Attachment A.
PURPOSE:
To obtain Board authorization for the General Manager to execute
Change Order No. 4 in an amount not-to-exceed $1,880.00 to the construction contract with Cass Arrietta for the Vista Vereda and Hidden Mesa Road Water Line Replacement Project (Project).
AGENDA ITEM 4
2
ANALYSIS:
The District provides water distribution service and sanitary sewer collection service in the Jamacha drainage basin located in the
northern area of the District. The existing 12-inch Cement Mortar Lined and Coated (CML&C) Steel pipe that serves as the distribution
main for the western portion of the 978 Pressure Zone along Vista Vereda to Hidden Mesa Road was constructed in 1959. Several water main breaks have occurred in the area that have led to a
determination that the pipeline has reached the end of its useful life and should be replaced. The original pipeline was constructed
in easements prior to any development in the area. Over the years, with the subdivision of properties and construction of homes, the difficult to access easements are no longer a desirable location for
placing an important transmission water main. This Project moves the transmission main for this area into Hidden Mesa Road.
The Project scope of work generally consists of construction along Vista Vereda and Hidden Mesa Road of approximately 3,700 linear feet of 12-inch Polyvinyl Chloride (PVC) water line and 400 linear feet of 8-inch PVC water line, including appurtenances, restoration of
services, surface restoration, traffic control, and all testing andinspection, as required by the Contract Documents.
At the November 7, 2018 Board Meeting, the Board awarded a construction contract in the amount of $2,848,364.00 to Cass Arrieta.
Since the award of the construction contract, there have been three (3) Change Orders approved.
Change Order No. 1, which totaled $45,750.67, compensated the contractor for several items associated with the Hidden Mesa water
line construction including: additional cut and cap of the existing mainline to minimize future customer impacts; realignment of the
planned main to resolve utility conflicts; additional asphalt paving, as required by the County permit; and reconciliation of unused allowance items. Contract time was also adjusted for weather impacts
and for impacts due to the added work. In total, Change Order No. 1 added twenty-nine (29) calendar days to the contract.
Change Order No. 2, which totaled $115,213.59, compensated the contractor for several items associated with the Vista Vereda water
line construction including: revisions to the alignment, profile, and sequence of connection for the planned water main tie-in at the Vista
Vereda/Vista Grande intersection; encasement of the existing sewer to meet the State Water Resource Control Board – Division of Drinking Water separation requirements; mainline grade revisions to the
profile of the planned water main within Vista Vereda due to existing
3
utilities; and credit adjustments for unused bid allowance items.
Contract time was also adjusted for impacts resulting from the added work. In total, Change Order No. 2 added ninety-three (93) calendar days to the contract.
Change Order No. 3, which totaled $1,998.18, compensated the
contractor for a modification of the planned profile for the 12-inch connection to the 978 Reservoir pipeline on Vista Vereda and quantity adjustments to sixteen (16) contract bid items resulting from field
conditions. Contract time was also adjusted for impacts resulting from the added work. In total, Change Order No. 3 added eighteen
(18) calendar days to the contract.
Change Order No. 4 (Exhibit B), which is the subject of this staff
report, serves to close out the construction contract and includes the following items associated with the water line work on Vista
Vereda and Hidden Mesa:
•Additional erosion control measures to improve the existing
draining conditions which were impacted by the project.
•Reimbursement for District personnel and equipment costs
incurred during the cellular concrete spill cleanup.
•Reconciliation of Bid Item No. 32 Reinstall Chain Link Fence dueto field conditions.
In total, the cost associated with the items in Change Order No. 4 is $1,880.00. There were no time impacts associated with this change as provided in Exhibit B.
As of November 25, 2019, the Project was substantially complete with punch list items remaining. These punch list items include final
restoration associated with a cellular concrete spill that occurred in early November 2019. The District has required the contractor to secure releases from affected property owners as a condition of
contract acceptance.

SUBJECT:Approval of Change Order No. 6 in an amount not-to-exceed $40,125.89 to the Construction Contract with Pacific Hydrotech
Corporation for the 870-2 Pump Station Replacement Project
GENERAL MANAGER’S RECOMMENDATION:
That the Otay Water District (District) Board of Directors (Board) authorize the General Manager to execute a Change Order No. 6 to the existing construction contract with Pacific Hydrotech Corporation (Pacific Hydrotech) in the amount of $40,125.89 for the 870-2 Pump Station Replacement Project (Project) (see Exhibits A and B for
Project location).
COMMITTEE ACTION:
Please see Attachment A.
PURPOSE:
To obtain Board authorization for the General Manager to execute Change Order No. 6 in the amount of $40,125.89 to the construction
contract with Pacific Hydrotech for the 870-2 Pump Station Replacement Project.
AGENDA ITEM 5
2
ANALYSIS:
The District’s existing High Head (870-1) and Low Head (571-1) Pump
Stations constructed in 1962 and 1966, respectively, have reached the end of their useful lives. The 870-2 Pump Station Project will
replace these facilities and includes replacement of existing Reservoir inlet/outlet piping, construction of recirculation system pumps, and a chloramine disinfection booster system. Improvements of
the access road and the installation of utilities for electrical, gas, sewer, and communication services are also included.
The 870-2 Pump Station Replacement Project also includes the replacement of the 571-1 Reservoir (36.7 MG) floating cover and
liner. The 571-1 Reservoir was originally built in 1967. In 1993 the District retrofitted the existing Reservoir to install a
reservoir liner and floating cover. The existing liner and floating cover were more than 24 years old and nearing the end of their useful lives. As part of the overall Project, the existing Reservoir outlet stub-out piping located beneath the Reservoir was replaced, which allows the new 870-2 Pump Station to simultaneously perform its
primary function (pump from the 571-1 Reservoir to the 870-1 Reservoir), recirculate the 571-1 Reservoir, and also achieve a future function (pump from the 571-1 Reservoir to the 624 Pressure Zone). The replacement of the cover and liner under this Project mitigates having to take this critical Reservoir out of service a
second time within the next few years.
The demolition of the Low Head and High Head Pump Stations will be completed at a later date (not part of this Project) when the new 870-2 Pump Station has been brought online and completed its warranty
period.
At the July 5, 2017 Board Meeting, the Board awarded a construction contract in the amount of $16,925,900.00 to Pacific Hydrotech. Since the award of the construction contract, five (5) change orders have
been approved.
Change Order No. 1, which totaled $26,269.83, compensated the contractor for changes associated with the 571-1 Reservoir cover and liner improvements. These changes included provisions for additional
cover buoyancy floats; replacement of existing unsalvageable batten bar anchor bolts; contractor reservoir disinfection in lieu of
contract specified District disinfection; weather related days; and an adjustment to the contract milestone date for the 571-1 Reservoir. In total, Change Order No. 1 added twenty-seven (27) days to the
contract.
3
Change Order No. 2, which totaled $48,698.12, compensated the contractor for changes including the following: modifications to the new electric meter room to accommodate San Diego Gas & Electric
accessibility requirements; modifications to provide two (2) 250-gallon aqueous ammonia tanks in lieu of one (1) 550-gallon tank to
better serve Station operations; provisions for two (2) 30-inch magnetic flow meters in lieu of ultrasonic flow meters to provide more resiliency and flexibility with anticipated flow conditions; and
repairs to an existing rectifier electrical conduit adjacent to the access road. Change Order No. 2 also addressed contract time
including weather days. In total, Change Order No. 2 added sixteen (16) days to the contract.
Change Order No. 3, which totaled $64,864.00, compensated the contractor for several changes including the following:
modifications to the dimensions of the backup generator concrete foundation pad; addition of structural support members for the heating, ventilation, and air-conditioning (HVAC) equipment and emergency generator muffler; revisions to the Stations louvers and associated masonry; installation of door louvers for the compressor
room doors; increasing the discharge piping on the 570 zone (recirculation) pumps to 18-inches; revisions to provide a sewn protective thermal insulation jacket with clips for the emergency generator muffler and exhaust piping; modifying the emergency generator exhaust roof penetration to simplify future muffler
removal/servicing; and consolidation of exterior lighting controls in a new contactor and control panel. Change Order No. 3 also addressed
contract time including weather days. In total, Change Order No. 3 added twenty-five (25) days to the contract.
Change Order No. 4, which totaled $49,157.89, compensated the contractor for several changes including the following: surge
protection for indoor devices; additional pipe supports; spare engine exhaust catalysts; modification to Victaulic couplings; and relocation of chemical analyzers. Change Order No. 4 also reconciled
credits associated with the unused portions of the Environmental/Regulatory Compliance and Reservoir Improvement
Allowance items. Change Order No. 4 also addressed contract time including weather days. In total, Change Order No. 4 added forty-four (44) days to the contract.
4
Change Order No. 5, which totaled $95,725.00, compensated the contractor for several changes including the following: profile and alignment revisions to the 66-inch and 30-inch discharge yard piping
and suction header elevation; modifications to the Type D emergency batteries and test switch locations; addition of a fuel containment
structure; providing position switches at the surge tank isolation valve; modifications to the thermal insulation for the pump engine coolant line piping; fire rated door hardware at door D-12; addition
of bollards and a metal protective enclosure at the diesel fuel lines entrance location to the Pump Station; revisions to the suction
header platform handrail; revisions to the pump engine natural gas pipe sizes; modifications to the cable tray support; ethernet communications to the pump engines; additional costs associated with
dewatering existing vault No. 7; elevation and layout modifications to the suction header walkway and engine platform structures; and
credits for unused items. Change Order No. 5 also addressed contract time including weather days. In total, Change Order No. 5 added thirty-eight (38) days to the contract.
Change Order No. 6, which is the subject of this staff report,
provides for the following twelve (12) items, as detailed in the attached Exhibit C:
1. Credits associated with revisions to chain link fencing.2. Modifications to the overhead crane electrical feed circuit.
3. Installation of flashing around pump engine exhaust canopy roofpenetration.
4. Handrail and steps at the fuel containment structure.5. Incorporation of handwheels on all suction header valves.6. Type II gate well frames and lids.
7. Additional conduit between CP-100 and the telephone backboard.8. Additional electrical grounding of the gas engines.
9. Custom grade adjustment for the oil interceptor.10. Relocation of pump engine batteries.11. Modifications to the planned hydroseed mix.
12. Addition of days due to weather impacts.
In total, the cost associated with the items in Change Order No. 6 is $40,125.89. Time impacts associated with this change are also provided in Exhibit C. The twenty-seven (27) additional days added
to the contract will result in a revised total contract duration of 977 calendar days.
As of March 2020, the physical construction of the 870-2 Pump Station is approximately 95% percent complete and Project startup has begun.

Contract / P.O. Change Order No. 6 page 3 of 3
Reason:
Item No. 1:
During fence layout discussions it was determined that; fencing was no longer required around the pump engine pad, deletion
of the vinyl coating on the fence fabric would provide a consistent galvanized fabric with adjacent District fencing and
incorporation of a new 14-foot vehicle double gate between the Pump Station site and Sheriff facility would be beneficial for
alternate access. This Change Order is required to implement the required modifications resolving all costs associated with COR
99.
Item No. 2:
The Contract specified overhead crane circuit breaker, conduit and electrical conductor feeder size. During submittal review it
was determined that the submitted crane required a larger circuit breaker, electrical conductor feeder size and conduit to
accommodate the provided equipment. This change order is required to implement the required modifications resolving all costs
associated with COR 100.
Item No. 3:
The Contract did not provide flashing at the pump engine penetration through the canopy as requested by Operations &
Maintenance. This change order is required to provide the requested flashing resolving all costs with COR 102.
Item No. 4:
During construction it was determined that the fuel containment area would benefit from incorporation of handrail and steps to
improve safety and simplify ingress/egress for diesel fuel transfer pump maintenance. This change order is required to provide
the handrail and steps resolving all costs with COR 104.
Item No. 5:
The Contract Documents provided a T-handle wrench nut for suction header valve operations. It was determined that
handwheels with the same steel coating as interior piping would provide increased functionality. This change order is required
to implement the modification resolving all costs with COR 106.
Item No. 6:
During construction it was determined that the plans did not incorporate the District standard two-piece gate well lids as part of
the included details. This change order is required to implement the modification resolving all costs with COR 107.
Item No. 7:
The Contract did not identify a conduit pathway between the telephone backboard and CP-100. During construction it was
determined that a conduit pathway would mitigate potential mechanical damage to the datalink required between the backboard
and CP-100. This change order is required to install the conduit and resolve all costs associated with COR 108.
Item No. 8:
Subsequent to pump engine installation it was determined that installation of an additional engine ground would mitigate
electrical noise on data and control conductors increasing operational reliability. This change order is required to implement the
modification and resolve all costs associated with COR 109.
Item No. 9:
The Contract specified installation of a specific oil interceptor. Resulting from the required depth of the drain line a custom riser
extension was required to facilitate access for cleaning and maintenance. This change order is required to implement the
modification and resolve all costs associated with COR 110.
Item No. 10:
Subsequent to installation of the pump engines, Operations & Maintenance requested relocation of the batteries from the engine
skid to ground level to facilitate access and simplify future battery replacement by relocating the batteries closer to a vehicle
access point. This change order is required to implement the modification and resolve all costs associated with COR 111.
Item No. 11:
During submittal review it was determined to change the hydroseed mix design and seed content. This change order is required
to implement the modification and resolve all costs associated with COR 113.
Item No. 12:
Contract Documents Section 00700-8.5 provides for no cost time extensions due to weather impacts on the project progress.
Weather impacted the project eight (8) days between December 16, 2019 and February 29, 2020. The project was impacted
on December 23, 26 and 27, 2019, January 17, 21 and 22, February 10 and 11, 2020 due to weather.
