Re: Change Order 7 for 24th Ave Reconstruction Project C I P No. 0053
Budget Account No: 303.303.053.595.30.63.00 Halme Construction Contract 08-006
This change order pays for two force account items: 1) a residential sewer service repair and
2), the cost to extract pea gravel from around utility adjustments.
Item 1 The residential sewer service at E 15806 24th Avenue was destroyed when CB 6 was
installed (Project Station 11+24, 17.5' RT). The original sewer service was installed by Vera
Water and Power. When the County assumed operation of the sewer system in this area, they
did not get as-builts for the services. The service location was not shown on the plans, and the
County did not paint the locations as part of the utility locate request. CB 6 replaced an existing
catch basin at the same location. The broken pipe was below the bottom of the excavation
made for the CB, so the trackhoe operator did not see evidence of a broken pipe. The
homeowner was not living in the residence, during construction, so the blockage was not found
until after the street was paved. After the County verified that the break was under the Catch
Basin, I issued Field Directive 15 to the Contractor to repair the service under WSDOT Force
Account procedures.
The cost of this work is $6,991.58. See the attached E 15806 24th Ave. Sewer Service Repair
Force Account Spreadsheet. The project was physically complete and the public had use of the
street during the repair work, so the work does not impact contract time.
Item 2 After the base lift was paved, Halme Construction adjusted valve boxes, manholes and
catchbasins to final grade by sawcutting the asphalt and excavating with Vactrucks on August
19th. The vactrucks allowed the Contractor to minimize the holes in the asphalt and the
resulting excavations were just large enough to remove the cover plates and set the utility rim or
cover to finish grade. There was not sufficient room to compact the crushed surfacing top
course with traditional "jumping jack" compaction equipment. Halme proposed placing pea
gravel around each adjustment. I approved the placement of pea gravel. On the morning of
August 20, I inspected the adjustments and found the top of the pea gravel loose. After
consultations with COSV pubiic works staff, I directed Halme to remove the pea gravel and
replace with Controlled Density Fill (CDF) under Force Account. In the future all utility
adjustment excavations will be backfilled with CDF. The cost of the Vac truck is $1,231.18.
Total cost (incl. tax) for this Change Order work is $8,222.76, paid for by the City of Spokane
Valley.
