Authorization
REQUEST:
Public Works Department is Requesting Authorization to Retain the
Services of Solan Trucking & Excavating for the Screening of Soil of
Construction Debris and Organic Material and Removal from the
Public W orkslUtility Complex.
PURPOSE:
To enter into a contract with Solan Trucking & Excavating for the
screening of the soil excavated from the Public W orks/ Utility Complex site
to remove assorted construction debris and organic material and dispose of
the material at a not to exceed cost of$31,125.
CONSIDERATIONS:
Installation of underground utilities and the excavation of storm water retention
ponds at the Utility/Public Works Compound revealed an unexpected amount of
construction debris and organic material such as tree trunks and stumps. The material
made the soil unsuitable for fill in areas which required the grade of the site to be raised.
Additional unsuitable material was also found underneath the foundation area of
the Operations Building. This material had to be excavated and replaced with clean soil as
previously approved by Commission on September 7,2006. The volume of material was
not reflected in the findings of the soils report and what the site development contractor
had included in the bid.
It is estimated that amount of material is between 4,000 and 5,000 cubic yards or
the equivalent of 200 to 250 truckloads. The cost to haul and dispose of this material was

priced at $230 per load. The total cost to dispose of the material would be between
$46,000 and $57,500 if it was not screened. Solan Trucking has been awarded the
contract for hauling fill material with Orange County.
It is estimated that if the material is screened, we can reduce the amount of
material to be hauled away by 75%. This would reduce the disposal cost to an estimated
$11,500 to $14,375. The cost of screening the material is $9,000. This brings the total
estimated amount of the operation to screen and remove the debris to $23,375. Additional
cost would be the hourly operating cost of a front end loader and dump truck on site to
load the material into the screen and move the clean fill to the onsite storage area.
Including these ancillary charges, the estimated cost is $31,125.
To offset this cost is the recovery of more than 3,000 cubic yards of clean fill to be
used by the Public W orks/ Utility Department. The value of this fill dirt is approximately
$22,500.
FUNDING:
Funding for this expenditure would come from the Utility/Public Works Capital
Project Fund (311-65000-30037).
RECOMMENDA TIONS:
The Public Works Department recommends authorization to contract with
Solan Trucking & Excavating for the screening and removal of debris at a not to
exceed cost of $31, 125.00 payable from line code 311-65000-30037.
