APPROVED BY:
Rod Posada, Chief of Engineering
German Alvarez, Assistant General Manager
Mark Watton, General Manager
SUBJECT: Change Order No. 2 to the Contract with TC Construction, Inc.
for the La Presa System Improvements Project
GENERAL MANAGER’S RECOMMENDATION:
That the Otay Water District (District) Board of Directors (Board)
approve Change Order No. 2 to the existing contract with TC
Construction, Inc. in an amount not-to-exceed $42,412.96 for the La
Presa System Improvements 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. 2 in an amount not-to-exceed $42,412.96 to the
contract with TC Construction, Inc. for the La Presa System
Improvements Project.
ANALYSIS:
At the November 2, 2011 Board Meeting, the Board awarded a
construction contract in an amount of $978,995 to TC Construction for
the La Presa System Improvements Project. Change Order No. 1 (see
AGENDA ITEM 3
2
Exhibit B) was approved by the General Manager in February 2012 for
$31,906.39, bringing the total contract amount to $1,010,901.39.
The Project consists of several components which includes, the
demolition to the existing facility at the La Presa Site,
installation of a new pressure reducing station, installation of
various interconnections throughout the 640 pressure zone, and the
demolition of the Dorchester Reservoir and pressure reducing station.
This Project eliminates the 590 pressure zone and those facilities
that are no longer needed. It will improve the reliability of water
delivery to the District’s customers and improve the operations and
maintenance of the District’s system.
TC Construction, Inc. is complete with the Project except for soil
remediation at the Dorchester site and minor punch list items such as
paving, painting of above ground piping, and clean up. Change Order
No. 2 (Exhibit C) includes a variety of items including time and
materials for additional potholing, revisions to the SDG&E connection
at the La Presa site, and various credits for deleted items in the
contract.
The following is a table summarizing the items in Change Order No. 2.
The Location column depicts the general location for each item as
shown in Exhibit A:

1 Additional Potholing at Paradise
Valley Road Site 6 $13,554.83

In summary, the net increase to the Project for Change Order No. 2 is
$42,412.96. Change Order No. 2 brings the total Change Order amount
to $74,319.35 or 7.6% of the total contract value.

in the amount of $42,412.96.
Item 1: Additional Potholing at Paradise Valley Rd. (COR#9)
Item 2: Electrical & Control Revisions (COR #10)

Item 14: Dewatering Allowance Credit
See attached Change Order Requests 9 through 20 (COR #17 was not used) from TC Construction.
REASON:
Item 1: During the pothole excavation of the 42-Inch pipeline at the Paradise Valley Rd.
interconnection, TC encountered ¾” rock backfill material. As this material was excavated, the
excavation became much larger than anticipated because the rock would fall into the trench and
undermine the road. The backfill material was unknown prior to excavation and this item represents
the additional time and material to excavate the ¾” rock material to create a safe trench to perform
the work. This item results in a cost of $13,554.83
Item 2: At the La Presa site, the connection to SDG&E was converted from an overhead source to
an underground vault connection. This item covers the time and material to install additional conduit
and relocate the transformer. This item results in a cost of $3,710.44
Item No. 3: TC could not locate the existing 6-Inch water main on San Carlos and Grand Ave. for
the proposed interconnection. TC potholed the 6-inch water line in a different location and located
the water line to perform the interconnection. This item is for the time and material for the additional
pothole and results in a cost of $1,611.45
Item No. 4: The quantity of the contaminated soil removed at the La Presa Site exceeded the
contract value. A portion of this item is for the additional costs to remove and haul off the additional
material. This item also includes a credit to the contract for the deletion of the sound wall. During
construction it was discovered that the sound wall was not necessary. Additional credits such as,
P:\WORKING\CIP P2370 - Dorchester (see P2471)\Construction\Change Orders\Change Order No. 2\CO #2.docx
reducing the DG paving, deleting support blocks, reducing the depth of excavation for the pipe at La
Presa, and for deleting two cut and plugs are also included in this item. The net value of this item is
a credit for <$25,910.00>
Item No. 5: Rock was encountered during construction for the Paradise Valley Road
Interconnection. This was an unknown condition and the contractor performed the rock excavation
on a T&M basis. The alignment of the interconnection was in close proximity to the County Water
Authorities’ aqueduct, therefore precautions and safe rock removal methods were used to perform
the work. This resulted in a slower production (17 working days); however, it protected the
surrounding utilities including the CWA aqueduct. The contractor used Dexpan which is a non-
invasive rock breaking method by drilling holes into the rock profile, pouring the Dexpan material in
the holes, then over time letting the material expand and crack the rock for removal. This item results
in a cost of $55,687.18.
Item No. 6: The original plan shows the pressure transmitters outside of the SCADA enclosure. To
protect them from the outside elements, they were installed inside the enclosure. This items covers
the time and material to install the transmitters inside the enclosure resulting in a cost of $317.21
Item No. 7: This item is the time and material to install additional conduits for future security use for
automatic gate operators, security cameras, access cards, etc. and results in a cost of $3,157.37
Item No. 8: The conduit for the power connection from SDG&E was to be provided by the County’s
contractor as part of the Jamacha Road Widening Project. The contractor installed the conduit to the
District’s property line; however, an unknown utility conflicted with the connection point for the
District’s property. This item covers the time and material to install conduit below the conflict to make
the necessary connection to SDG&E and results in a cost of $3,857.00
Item No. 9: Not Used. This Change Order Request was for an additional enclosure inside the
SCADA cabinet and was denied. The proposed modifications were not necessary.
Item No. 10: The La Presa site experienced a number of break-ins, vandalism, and theft throughout
the duration of the project. In an effort to curb the security breach, TC Construction hired a security
guard for night and weekend watch to protect the facility. This action proved to be successful. This
item is for half of the cost to cover the security guard expense and results in a cost of $4,695.60
Item No. 11: The interconnection at the Dorchester site required additional materials not shown on
the plans to make the proper connection. In addition, the original plan at the Dorchester site required
4-inches of DG material to grade the site. The native material proved to be sufficient and the DG
material was deleted from the contract. In lieu of the DG, hydroseed material was placed at the site
to reduce erosion. Lastly, this item covers material credits for the 10-inch waterline relocation at the
entrance to Pointe Parkway. It was discovered that the existing pipe to be removed was PVC, not
asbestos cement pipe; therefore, the pipe was not considered hazardous and did not require special
handling procedures. This item results in a credit of <$9,021.99>
Item No. 12: The District delayed TC Construction by a half day due to water remaining in the
Dorchester Reservoir when they were ready for demolition. This item covers the cost for a half day of
standby delay to drain the last 4 feet of water from the reservoir. This item results in a cost of
$753.87
Item No. 13: The quantity of the contaminated soil to be removed at the Dorchester site will exceed
the contract value. This item is for the additional costs to remove and haul off the additional material.
