Subject:APPROVE Change Order No. 1 with Cleary Bros. Landscape for the Landscaping at Walden Green Phase 2, Pleasant
Hill, Project
BACKGROUND: (CONT'D)
In 2005, construction was completed on the first phase of the linear greenway ("Walden Green Phase 1"), between
Treat Boulevard and Coggins Drive. On January 24, 2012, the Board of Supervisors awarded a construction contract
in the amount of $536,019 to Cleary Bros. for the Walden Green Phase 2 Project, which extends the linear greenway
from Coggins Drive to Mayhew Way, a length of approximately 1/4 mile.
Subsequent to award of the construction contract, and before construction began, arsenic-contaminated soil was
discovered on the site. Public Works hired Engeo Inc. ("Engeo") to survey the site and determine the extent of the
contamination. Based on their findings, Engeo prepared a report on procedures to be followed by Cleary Bros. in
performing the construction work. The report was reviewed and approved by the County Health Services
Department's Hazardous Materials Program.
This change order in the amount of $52,585 includes the additional work that Cleary Bros. must perform to comply
with proper procedures in handling the contaminated soil and to add landscaped mounds that will allow for on-site
use of the contaminated soil. The change order is authorized by Public Contract Code Section 20137. The Public
Works Director recommends that the Board approve Change Order No. 1 in the amount of $52,585 and authorize the
Public Works Director, or designee, to sign it for the County.
CONSEQUENCE OF NEGATIVE ACTION:
The Walden Green Phase 2 project would not be able to proceed without this change order, because it is not possible
to perform the contract work without disturbing the arsenic-contaminated soil.
CHILDREN'S IMPACT STATEMENT:
Not applicable.
