Subject: 8`h Street District 24 20A Conversion, in the City of National City
Dear Steve,
Harris & Associates appreciates the opportunity to present this proposal to provide additional
professional services to assist the City with the subject project. The following presents the our project
understanding, scope of services and fees.
PROJECT UNDERSTANDING
The City of National City is taking the lead in designing and constructing the joint trench associated
with 8th Street District 24 20A conversion project (Project). The Project is limited to providing
trenching, backfill, substructures, conduit and pertinent work (Trenching Items of Work). All cabling
and equipment installation design and construction work will be performed by SDG&E and the
respective utility companies. Our proposed scope of work for this phase of the project is to assist the
City with reviewing SDG&E and utility companies' plans to verify conflicts with existing field
conditions, and prepare a utility composite plan.
Our scope of work is limited to the items outlined in the scope of services below and our estimated
effort as broken down in our proposed fees.
Scope of Services
1.1 Review Meetings
We will schedule and attend meetings with SDG&E, AT&T and Cox Communications to obtain each
utility's final designs and agreements. We will also verify accuracy of design and cost methodology
and rule application to discuss project issues and obtain feedback. Six (6) coordination meetings are
included in the scope of this proposal. Copies of meeting minutes will be provided to the City.
1.2 Topographic Survey
Our sub -consultant, Right -of -Way Engineering Services, Inc. will establish record street right-of-way
and a center line survey for the additional survey beyond the 8th Street Improvements project limits
(east of D Avenue to Highland Avenue)

1.3 Base Mapping
Utilizing the aerial topographic survey obtained previously and survey data obtained in the Task 1.2,
we will prepare base maps for the additional areas east of D Avenue to and on Highland Avenue.
Base maps will be prepared in plan only formats.
Base maps will include roadway center line, right-of-way, manholes, valves, water meters, all visible
utility boxes, above and underground utilities. All base maps will be prepared in AutoCAD.
1.4 Utility Mapping
Obtain and plot all underground utilities within the additional project limit within the 8th Street
District 24 conversion boundary. Additional notification to all wet utilities within the conversion
boundary will also be conducted.
1.5 Site Analysis
1. Overlay the current SDG&E plans (dated 10/4/07), AT&T and Cox trench, conduit and
substructure designs onto base maps to use a reference document to review the 8th street
Improvements civil plans, electric design and existing field conditions conflicts.
2. Visit project site to identify existing utility systems, probable source locations, and potential
contractor constraints. Photograph areas of significance including private property impacts
associated with the current and new utility service routes and meter locations.
3. Visit each property affected by the undergrounding to determine the service trench route on
private property as well as determine the modifications to the service panel needed to accept
underground electric service.
4. Identify any incompatible issues from our field findings between the utility company designs, the
8th street Improvements civil plans, and the field conditions.
1.6 Utility Composite
1. Utilizing the current SDG&E electric trench, conduit and substructure design, the AT&T design,
and Cox design, prepare a composite exhibit utilizing the base maps.
2. Re -draft the current SDG&E electric Trenching Items of work design on the base maps replicating
typical SDG&E design and appearance. This re -drafted design will then be provided to SDG&E
for their approval and use to have SDG&E's design confouui to the current base map and 8`h Street
Improvements plans.
3. Coordinate with SDG&E for their final engineering modifications to the electric Trenching Items
of Work design, and cable and hardware design, DBL material listing and quantity sheets, and
Rule 20A agreements.
4. Utilizing the pictures taken during our site review, create an exhibit that can be attached to the
Utility Composite reflecting the locations and description of the potential issues associated to the
Harris & Associates..
