RE: Camarillo Hills Drain Replacement At Ventura Blvd - Contract No. SD-5052 Dear Mr. Grubb,
As discussed, the original proposal assumed that soil cuttings produced during the geotechnical field investigation could be re-used to backfill the boring holes. The draft ISA by Geocon West January 10th, 2022, indicates “Any excess soil generated from construction excavations should be properly characterized for potential contaminants of concern (including metals and pesticides) prior to offsite reuse or disposal.”
The attached proposal from Earth Mechanics outlines the change in scope needed to test and dispose of the soil cuttings per the new ISA information. This includes switching the boring machine from a hollow stem auger to and rotary wash, backfill of the holes with cement-bentonite slurry, and collection, testing and disposal of the soil. The 55-gallon drums will be stored at the City Yard at 283 Glenn Dr until the tests have been completed and the appropriate waste facility is identified.
The Total fee for this change order request is $9,400. The work will be billed on a time and materials basis, not to exceed the total amount of $9,400.
Sincerely,
Daniel Weddell
Vice President

AMENDMENT TO GEOTECHNICAL SERVICES SCOPE OF WORK
Camarillo Hills Drain RCB Replacement Project
City of Camarillo, Ventura County, California
EMI Project No. 22-101
Date: February 4, 2022
Additional Scope of Work
Earth Mechanics, Inc. (EMI) original scope and budget for the geotechnical field work involved using a hollow-stem auger drill rig and using the spoils (mixed with cement) to backfill the borehole excavations – the assumption was that the in-situ soils are not contaminated and could be reused as backfill. A City review comment, on the EMI work plan, asked to describe the process for testing soils for contaminants prior to using them to backfill the borehole. Because soil testing cannot be performed in the field, during an investigation, EMI proposes changing the drilling method to rotary-wash, which includes backfilling the boreholes with slurry and disposing the soil spoils that are generated from the borehole excavations. This amendment includes the following changes to the geotechnical scope of work:
1. Use a rotary-wash drill rig instead of a hollow-stem drill rig to excavate boreholes; backfill boreholes with cement-bentonite slurry.
2. Collect the soil spoils in 55-gallon steel drums.
3. Analytical lab tests on samples of the soil spoils for contaminants (for waste characterization).
4. Rent one support truck to move drums to City-designated storage site.
5. Arrange for the removal of the steel drums from the site after contaminant testing is completed.
Additional Cost
The additional cost for the added geotechnical work described above is estimated to be $9,400.
The $9,400 additional cost includes $7,900 for field work changes and $1,500 for outside analytical laboratory testing for contaminants (the cost for conventional geotechnical laboratory testing remains unchanged).
