THE CONTRACT IS MODIFIED AS FOLLOWS:
Description of Change:
The Contractor is directed to install the revised cathodic protection as detailed in the
revised diagram for the cathodic protection and the revised cathodic protection
standard plans which are attached to this Change Order.
The proposal is revised as follows:
13-A14 -Flaggers, 65 Hours @ $70.20/Hour = $4,563.00
13-A15 -Other Traffic Control Labor, 30 Hours @ $71.60/Hour = $2,148.00
13-A34 -Temporary Pavement, 10 Tons @ $235.00/Ton = $2,350.00
13-Bl0 -Bank Run Gravel Borrow for Trench Backfill Water Main, 80 Ton, $20.15/Ton,
$1,612.00
13-B17 -Corrosion Protection, Pipe Joint-Bonding, Test Stations, -1 LS @
$13,680.00/LS = -$13,680.00
13-B32 -Naturally Occurring Pipe Zone Bedding for the Water Main, 55 Ton @
$20.80/Ton = $1,144.00
13-B33 -Corrosion Protection, Pipe Joint Bonding, Test Stations, 1 LS, $38,000.00/LS,
$38,000.00
SP 7-11.3(3) paragraphs 1. 2. 3. and 4 are deleted in their entirety.
SP 7-11.3(5) paragraphs 1. 2. 3, and 4 are deleted in their entirety.
SP 7-11.3(6) paragraphs 1. 2. and 3 are deleted in their entirety.
Reason for Change:
13-B17-Corrosion Protection, Pipe Joint-Bonding, Test Stations
13-B33 -Corrosion Protection, Pipe Joint Bonding, Test Stations
The Plans required the Contractor to install two Type FF test stations and to
install Cathodic Protection per the City of Renton Standard Plan CP. This required
the Contractor to excavate to the Seattle Public Utilities pipelines and to the
locations of the Cathodic Protection Test Stations. The specifications also
required the Contractor to coordinate with SPU for SPU to perform the welds to
the SPU pipelines.
SPU told the City of Renton Water Department that they would not perform this
work.
Change Order No.

The City of Renton Water Department determined that revisions to the City of
Renton Standard Plan CP were needed in order to construct a functional version
of the Cathodic Protection as shown in the plans.
After receiving the revised plans which accurately represented the desired
Cathodic Protection, the Contractor proposed pricing to install the revised
Cathodic Protection and to complete the work in coordination with the City of
Renton Water Department instead of SPU for the welds to the SPU transmission
lines. This pricing was not acceptable to the City of Renton Water Department.
Therefore, the City of Renton Water Department revised the Cathodic Protection
to a pared down version which did not require excavation down to the SPU
transmission lines.
Affects DBE Work: □Yes IZI No
Materials:
None.
Plans:
Revised Cathodic Protection Plans.
Equitable Adjustment:
This Change Order does include an equitable adjustment per Section 1-09.4 of the 2022
WSDOT/APWA Standard Specifications. See attached.
13-B33 -Corrosion Protection, Pipe Joint Bonding, Test Stations
An independent estimate was prepared for the cost to compensate the Contractor for
the work to perform the revised cathodic protection as described in this change order
and after the water main was installed. This was calculated to be $42,000.00. Based on
this calculation the Contractors quote of $24,251.44+$13,680.00=$37,931.44 was
accepted and rounded to $38,000.00.
Extension of Time:
The Time for Completion is extended _O_ Working Days.
Sections 1-04.4 and 1-04.5 of the 2022 WSDOT / APWA Standard Specifications shall govern
this Change Order. The Work of the referenced Contract is modified to include the changes
detailed herein. The payment provided for herein shall constitute the complete and final
settlement for all costs of labor, equipment, materials, overhead, profit, permit fees, and all
other claims that may be made by the Contractor as a result of this change.
