Attn: Mr. David Fait
Interim Deputy Director, PW/ Maintenance and Utilities
Subject: Proposal for Engineering Services; SS1902 6th Street Alley, Water, and Sewer
Improvements
Dear Mr. Fait:
AKM Consulting Engineers (AKM) is pleased to submit this proposal to provide engineering services for
the SS1902 6th Street Alley Sewer Repair Project. Our understanding of the project, proposed scope of
work,corresponding fee proposal,and the schedule are as follows.
PRO ECT UNDERSTANDING
The City of Seal Beach has a 6-inch diameter gravity sewer in the 6th Street Alley. The City lined a portion
of the pipe in 2012. Approximately 325 feet of the pipe (200 feet south and 125 feet north of the
centerline of Central Avenue) could not be lined due to"defects discovered". Two (2) 48-inch diameter
manholes were constructed on this line, one approximately 190 feet south of Central Avenue, and one
410 feet north of Central Avenue. The lining has experienced failures,which results in the City having to
clean this sewer frequently.
There is a 6-inch asbestos cement water pipe in the alley. This pipe has reached the end of its useful life,
and was identified for replacement in the City's 2012 Water Master Plan Update. Additionally, many of
the house service meters in 6th Street Alley are located on private property, and need to be relocated to
the public right of way.
The project will replace the existing 6-inch sewer with a new 8-inch sewer,preferably with steeper slope.
This will require a new connection to the 21-inch diameter sewer on Electric Avenue.The water line will
be replaced between Electric Avenue and Ocean Avenue Alley with an 8-inch pipe, and all services will
be located on the public right of way.
The alley pavement will be replaced within the public right of way,as well as in areas on private property
where the existing water meters are removed.
The total length of each improvement is approximately 1,230 feet. Due to the narrow width of the alley
and the number of improvements involved,we propose to prepare the plans at a scale of 1"=10' (6 sheets
of plans and profiles for water and sewer; 6 sheets of plans for the alley pavement replacement, and 4
sheets of details.
SCOPE OF WORK
We propose to implement the following scope of work:

SS1902 City of SeaL13ect h.
StveetAlley Solver 1Zepaie- Nave-in/yet-12,2018
1. Project Management and Meetings
We will start the meeting with a kickoff meeting to review and refine the scope of work,establish
lines of communication,and discuss the initial schedule.
We will submit monthly progress status reports along with our invoices,and meet with City staff
to review the progress and obtain additional information/direction.
We will conduct weekly in-house quality control review of the project, and address any issues
that may be identified.
2. Obtain and review all as-built utility plans
We will obtain the water, sewer, and storm drain information from the City, and gas, electric,
telephone, and cable facility information from the respective owners. We will maintain a utility
coordination log to ascertain that appropriate communication has taken place. We will verify the
visible facilities during field walk of the alignment.
3. Review CCTV Inspection Reports and Recordings.
We will review the CCTV data to locate the precise location of the sewer house laterals
4. Field Surveying
We will utilize the existing topography, and supplement it with field surveys, including cross
sections of the alley at approximately 20-ft intervals. The survey crew will dip all manholes and
catch basins,where they exist.
S. Geotechnical Investigation
We propose to conduct a geotechnical investigation to develop design recommendations for
bedding, backfill, shoring, and dewatering required for the project. The field work will include
two borings extending to 10 feet below the bottom of the proposed improvements
6. Potholing
This task involves potholing to determine precise location and elevation of existing utilities that
may interfere with the construction of the proposed water and sewer improvements. It will be
invoiced only if used.
7. Prepare Plans,Specifications,and Estimates for Sewer,Water,and Alley Improvements
This task will include walking the alignment with City staff to determine the extent of work to be
performed on private property where the pavement elevations do not match,where the existing
water meters are on private property, and where the existing meter boxes are not of the size
required by the current standards.
As described under project understanding,we propose to develop the plans at 1"=10'scale.
We will review the development of the plans with the City staff at progress review meetings,and
submit them at the 70% completion stage, along with technical specifications and construction
cost estimate. We will address the City's comments, and finalize the documents.
8. Project Close-out
We will prepare as-built drawings based upon the redlines provided by the contractor and the
City's inspector.

addendum,if necessary.
10. Engineering Support During Construction

requests for information during the construction.
SCHEDULE
We propose to complete the scope of work tasks 1 through 7 within 18 weeks of receipt of notice to
proceed. We will complete tasks 8 through 10 as required by the progress of the work.
FEE ESTIMATE
To complete scope of work described above,we estimate a budget of$180,928 will be required.The work

the project,including workhours,is attached to our proposal
