SCOPE OF SERVICES
for
City of Cathedral City
New Traffic Signal at Cathedral Canyon Drive at Canyon Shores
The scope of services is based on the request from City staff for ADVANTEC to provide professional
engineering services to prepare plans, specifications, and estimates (PS&E) for the installation of a new traffic signal at the intersection of Cathedral Canyon Drive at Canyon Shores. The project improvements include, but are not limited to,
traffic signal installation and signing/striping.
As an option, we included
traffic signal timing sheets and providing construction support throughout both the
bidding and construction
p
rocesses
.
The following scope of services provides project scope and fees.
SCOPE OF SERVICES
Task
1 Project Management, Coordination, and Meetings
ADVANTEC will provide project management
and
coordination activities to manage the work and tasks
identified in this scope of work. This includes coordination with project team and the City including bi -
weekly conference calls with the City’s Project Manager in order to provide up -
to
-
date project sta
tus,
discuss any concerns or issues, and follow
-
ups on any requests or action items.
ADVANTEC will conduct
up to three
in
-
person/virtual
meetings with City staff. The first meeting will be
conducted for the project kick
-
off
, the second will be conducted to discuss our results of the analysis/conceptual plans,
and the
third
meeting will be held after the 90% submittal for response to comments.
ADVANTEC will prepare meeting agendas, meeting minutes, and action items list for distribution after each meeting.
SCE Coordination
–
Since we are proposing a new traffic signal, this will require coordination with SCE to obtain service (i.e.
,
power) for the traffic signal and safety lighting improvements. ADVANTEC will coordinate with SCE to determine the service point location and feed to new traffic signal service enclosure. This typically requires filling out a SCE costumer service request form and coordinating design
requirements including potential design from SCE (conductors, conduit, pull boxes, etc. from the service point to the new service enclosure). Our coordination efforts under this task will minimize delays during construction.
Deliverables:
Project management and coordination; bi
-
weekly conference calls and conduct
up to
three
meetings with City staff
virtual
ly
or
at City Hall.
SCE coordination.

2 Data Collection and Field Review
ADVANTEC will coordinate with City staff
and
collect and review available data for use and reference associated with the traffic signal, signing
/
striping, and roadway improvements. ADVANTEC will conduct a thorough field review at the project intersection. Our field review will consist
of
but not
be
limited to
collecting the following:
All roadway features including curb lines, property lines, edges of pavement, edges of paved sidewalks, curb returns, curb ramps, driveways, and bus pads
Signing and striping
Nearby at
-
grade
utilities, catch basins, manholes, cabinets, sub
-
structures, vaults; and nearby
aboveground utilities, power poles/overhead lines, street lights, etc.
Other field conditions that might affect a design decision
ADA compliance and constraints
Upon completion of the above items, ADVANTEC will identify potential constraints that may be encountered in relation to the proposed improvements. This information will be used to prepare base mapping and proposed improvements at the project intersection.
Deliverables:
Data collection
inventory
matrix, project survey, field review notes, and photos.
Task
3 Utility Coordination
Utility notification and coordination will be required to ensure quality design and help eliminate utility conflicts during construction. Utility notifications will be provided to the various utility owners within the sphere of the project; the notificatio
ns will be prepared using the City’s letterhead. ADVANTEC will request locations for existing and proposed underground and overhead utilities, including high risk utilities. The utility information provided by the agencies will be delineated on the plans b ased on their record drawings
and our field review. The location of our proposed improvements will take into consideration of the existing utilities. In the event of any utility conflicts, ADVANTEC will coordinate the relocation of all utilities affected b
y the project. Our goal is to relocate their facilities prior to the start of construction of the project improvements. ADVANTEC will compile all utility coordination and information in a matrix format to include dates of notification, persons/utility noti
fied and responses from the utility company. Letters will be sent to the utility companies requesting their review and verification of their facilities during the preliminary and final plan submittals to obtain their concurrence with the information shown
on the plans.
Copies of this information will be updated upon receipt and provided to Cathedral City
at the scheduled
project meetings and/or as the information has been received. ADVANTEC will conduct utility coordination throughout the preliminary and f
inal design phases of the project.
Please note: ADVANTEC’s
fees do not include fees or costs associated with the processing and collection of as -
built plans or
documentation from the utility companies. Typically, fees are waived when submitting utility requests using the City’s letterhead.
Deliverables:
Utility notification and coordination, utility letters, utility plans and utility coordination matrix.
