ISSUE: Board authorization is required for the General Manager to execute a
professional engineering services agreement when aggregated revisions are expected
to total more than $100,000.
RECOMMENDATION: Authorize the General Manager to revise Agreement No.
039747 with DCM Consulting, Inc. for professional engineering services by increasing
the cost sealing from $98,000 to an amount not to exceed $134,000 for geotechnical
services under the Pleasant Hill- Grayson Creek Trunk Sewer Project, DP 8412.
FINANCIAL IMPACTS: The total estimated cost for the agreement revision is $36,000.
Adequate funds are currently available in the current budget for the Pleasant Hill —
Grayson Creek Trunk Sewer Project, DP 8412. No additional project funding is required.
ALTERNATIVES /CONSIDERATIONS: The Board could decide not to authorize the
revision of the professional engineering services agreement with DCM Consulting Inc.
However, doing so would prevent staff from completing the final geotechnical report
needed to substantiate the design and permitting for the project.
BACKGROUND: The Collection System Renovation Program has been an ongoing
series of projects dating back to early 1990's. Candidate sewer line segments are
identified, evaluated, and placed on a priority list for replacement or repair. Staff from
the Collection System Operations Division and Engineering Department work together
to identify candidate sewer lines based on several criteria including television inspection
(condition assessments) and grouped by geographical areas. Candidate sewer lines
have been identified in the City of Pleasant Hill in the neighborhoods between Pleasant
Hill Rd. and Mercury Way to Ardith Drive. The existing sewer mains in this area pose
several renovation challenges to meet current District Standards. The Pleasant Hill -
Grayson Creek Trunk Sewer Project, DP 8412 was recommended in the Collection

CREEK TRUNK SEWER PROJECT, DISTRICT PROJECT 8412
System Master Plan Update in 2000 and 2010 relating to future capacity considerations
from the Pleasant Hill Rd. corridor upstream from Mercury Way. Although the
Comprehensive Wastewater Master Plan will revisit the design criteria for capacity
projects, Staff has evaluated and has continued the design efforts for the Pleasant Hill —
Grayson Creek Truck Sewer project due to several critical and important reasons. This
project will provide relief to the deteriorating trunk easement sewers and provide Staff
the ability to implement necessary renovation work in Pleasant Hill. In addition, the City
of Pleasant Hill has been coordinating with the District in conjunction with their paving
plan in anticipation of this trunk sewer and other future renovation projects that are
required prior to road reconstruction. This project has been prioritized as critical to the
Collection System Program.
DCM Consulting Inc. is an experienced geotechnical company that has been under
contract with the District since September 2012 for this project. DCM Consulting has
completed the preliminary geotechnical investigation last year. The preliminary
investigation evaluated the entire alignment to identify the existing geologic settings and
to identify the areas necessary for refinement. The preliminary report assisted in the
early stages of the design and the evaluation of several alignment alternatives for the
new pipeline. This information was required and has been reported to the appropriate
agencies initiating the encroachment permit process. The agreement revision proposed
will finalize the geotechnical investigation, provide verification for staff regarding the
selected construction technologies, and assist with the constructability review of the
project.
Overall, Staff is currently working on revising the 50% design plans for the project and
acquisition of all necessary permits. The project involves the installation of 12,500
Lineal Feet (LF) of trunk sewers, ranging from 12 -inch to 24 -inch, approx. 2,900 LF of
which will be replacement of deteriorating piping. Construction of this project is planned
for 2015. This project is identified in the Fiscal Year 2014 -15 Capital Improvement
Budget (CIB), Collection System Program on page CS -36. The total estimated project
cost is $6,481,000. However, Staff has hired West Yost Consulting to assist in PEER
review and provide an updated cost estimate that will be included in the budgeting of
next year's CIB.
No additional funding to the project is required at this time. The following table
represents the current status of the FY 2014 -15 Collection System (CS) Program
budget:
