4 CITY OF ORANGE - ON-CALL TRAFFIC ENGINEERING SERVICES ( RFP NO. 24-25.24) H. Work Plan
The following sections describe typical task orders
carried out as part of on-call contracts illustrating our work plan.
1. Plans, Specifications, and Estimates
GTS will prepare plans, specifications, and estimates
(PS&E) to accommodate the construction requirements
for traffic signals, signing and striping, traffic control plans, and other ITS design tasks.
We typically anticipate producing plans for the
following:
• Street Improvement Plans – To accommodate
ADA compliant curb ramps and raised median
noses.
• Signing and Striping Design
• Traffic Signal Plan – To propose agreed upon
traffic signal improvements and operations based
on the developed recommendations.
The GTS team believes a detailed field review and
as-built plan verification will provide a good base
plan for a high-quality design plan and will result in
higher efficiencies (less time and costs). Prior to
preparing a base plan for the street improvement
and traffic engineering design, GTS will obtain copies
of available as-built drawings and other available
database/information pertaining to the project from the City and other agencies if needed. The field review will include identifying design constraints, verifying as-built information, and observing general site conditions.
We will document our findings with photos taken as
part of our field review. We will review the preliminary utility information and prepare and send notifications
to all utility companies known to operate within the
project area. Underground and overhead utilities will
be identified, and potential conflicts will be noted and resolved during final design.
Typical tasks could include:
1.1 Topographic Land Survey: The design survey
will be developed at 1”=20’ scale and will include the
following items:
• Sufficient spot elevations and breaklines to
accurately develop contours at a 1.0’ interval.
• Curbs, right-of-way (and jurisdiction boundary
line), flowlines, and gutters.
• Paving types.
• Roadway crown elevations and striping.
• Above ground evidence of utilities.
1.2 Street Improvement Plan: GTS will modify the
existing curb ramps to comply with ADA guidelines
at the intersection. GTS will utilize the topographic
land survey to produce the street improvement plan.
The street improvements will be limited to ADA curb
ramp reconstruction. GTS will perform a detailed ADA
evaluation. We will design all proposed curb ramps
per the standards agreed upon with the City. The
plans will clearly show limits of construction and curb ramp grades and details. The curb ramp details will be
prepared at 1”=10’ scale.
1.3 Signing and Striping Design: GTS will incorporate
any striping and signage modifications at the project
intersection on the corresponding traffic signal plan
if it is part of a signal design project, or will produce separate signing and striping plans.
Striping and signage services will include items like
improving existing bike lane signages, reinstalling
faded striping, or other striping or signage that may be required.
1.4 Traffic Signal Plan: Utilizing the traffic signal as- built plans, survey, and field investigation data, GTS
will prepare a traffic signal base plan at the intersection.
The base plan is the backbone to accurately design
proposed improvements. At this stage of the process,
a thorough review is performed on the base plan to
ensure accuracy prior to design. The base plan will
include centerline, right-of-way, relevant existing
street improvements, and existing traffic controls. We
will prepare the base plan in accordance with City’s
format and standards. If the intersection has shared
jurisdiction with other cities we will also work with their standards.
GTS has extensive experience in traffic signal design
and will utilize that knowledge to identify potential
conflicts before the project goes into construction. For example, proposed signal poles will be strategically
placed in the optimum location for driver/pedestrian
visibility and will adhere to ADA guidelines. We will
also evaluate any current deficiencies or sub-standard
equipment that should be upgraded to meet current
City agreed-upon standards.
We will provide a detailed traffic signal plan per City agreed-upon format, standards, and specifications.
The plan will propose approved signal phases, clearly
identifying all existing, proposed, and removed traffic signal equipment to correspond with the overall design
intent and shown existing and proposed improvements.
The traffic signal plan will be 1”=20’ scale unless
directed otherwise.
5 CITY OF ORANGE - ON-CALL TRAFFIC ENGINEERING SERVICES ( RFP NO. 24-25.24)
1.5 Utility Verification and Coordination: GTS will
request a contact list from the City of utility companies with facilities at the project intersection. We will
request utility maps and compile underground and
above ground utilities in a separate digital file. This file will be referenced into all relevant design plans and
clearly labeled to identify utility type, size, and owner.
This will allow us to identify any potential impacts and modify the design as necessary.
We will also send a notification to all utility companies within the project limits at the 70% and/or final design stage for their review to determine if there are any
possible conflicts with the proposed improvements.
GTS will work closely with the utility companies and
other City departments to resolve conflicts prior to
final design. A communication log will be preserved
throughout the project and provided to the City upon
request. GTS will provide coordination with electric
utility companies if the design includes modification to the service pedestal and/or point of connection (POC).
1.6 Specifications and Cost Estimates: GTS will
prepare the technical specifications using the City’s
boilerplate template or Caltrans required template
and required format. We will use the City-required
standards and specifications.
1.7 Pre-Construction Support: GTS will provide pre-
construction support services for this project after plans have been approved by the City and other agency. We
will attend pre-bid meeting and answer the questions
during the construction bidding process regarding the
design and specifications. If there are omissions or
conflicts in the design prior to the award to contractor, GTS will provide a plan revision.
1.8 Construction Support: GTS will provide
construction support services for this project during
construction. These services include but are not limited to attending a pre-construction meeting, responding to
questions during the construction, reviewing contractor submittals within 72 hours, responding to contractor’s
requests for information (RFIs) or Change Request
(CR), revising design plans per CR, maintaining a log
of all changes to approved plan set, reviewing and
making recommendations to Contract Change Order
(CCO), and providing progress reports.
1.9 As-Built Plan Preparation: After the completion
of project construction, we will request the redline
markings prepared by the project inspectors and/or
contractors on the signed design plans for preparation
of as-built plans. The as-built plans will be signed and submitted to the City for the completion of the project.
Sample Recent Relevant Projects:
• City of Carson: Provided HSIP-funded PS&E signal
design services at Figueroa St and Victoria St;
also provided PS&E services for the Dominguez
Channel Bike Path Design working with the City
and County
• City of Santa Monica: Provided ATP-funded PS&E
signal design, signing and striping, and street
lighting designs as well as traffic analysis per
Caltrans and City guidelines
• Orange County Fire Authority: Traffic signals in
Mission Viejo and Anaheim
2. Review/Prepare Traffic Signal Timing/Coordination
Plans
GTS will provide signal timing plan support to the City to address the changing traffic conditions. Our tasks
typically include the following:
2.1 Field Observations and Data Review: We will
review the provided signal timing parameters (yellow/
red timing, lead/lag timing, offsets, pedestrian timing, etc.) for potential inconsistencies between timing
sheets or other anomalies. We will also coordinate
with the City to open the traffic controller cabinets and verify existing controllers. We will also observe traffic flow patterns and signal operations during each peak
period along the corridor. Elements such as uneven
lane distributions, queue spillbacks, cut through
traffic movements, heavy truck or bus percentages,
congestion associated with school activity, and
friction factors affecting vehicle speed or intersection throughput will be noted. Crosswalk lengths will
be measured using aerial imagery to determine
appropriate pedestrian timing.
2.2 Traffic Data Collection: A 24-hour count will
be used to understand demand variability by time
and determine intersection and corridor peak hours.
GTS will collect turning movement counts with vehicle
classification at the project intersections. All turning movement counts will be classified to distinguish
vehicle classification, pedestrians, and bicycles.
Before travel time data may be collected if the City
desires.
2.3 Modeling: Using the collected traffic counts
and existing signal timing plans available to the City, GTS will develop Synchro and SimTraffic models to
understand existing condition operations at each of
the project intersections. An accurate understanding
of operational deficiencies is crucial to develop
improvements at the conceptual level. Based on the
results of our field visits and safety and Synchro/
SimTraffic analysis, GTS will develop a set of
improvements to be tested in the Synchro model for
future consideration. The following are few examples
6 CITY OF ORANGE - ON-CALL TRAFFIC ENGINEERING SERVICES ( RFP NO. 24-25.24) of such improvements:
• Lead/lag phasing order based on platoon arrivals,
turning movement volumes, and synch phase
assignments.
• Phase splits that provide sufficient time to meet
pedestrian minimums and minimize the frequency
of underserving queues, except where strategically
beneficial.
• Offsets that prioritize the primary direction of travel to the extent that flow directionality exists within
each period of implementation.
• Re-striping or modification to intersection approach
to change the lane configuration. For example,
provision of a dedicated turn lane or changing a
dedicated turn lane to shared movement.
Each set of proposed improvements will be vetted
for feasibility and tested in Synchro to determine
effectiveness in improving traffic operation. We
will work with the City to select a preferred set of
improvements, which will be included in the final
optimized Synchro model.
2.4 Signal Timing Sheets: GTS will develop a
spreadsheet of proposed signal timing parameters
such as yellow times, all-red times, walk times, flashing don’t walk times, minimum greens, lead/lad phasing,
and sync phases for each study intersection. Additional timing parameters such as minimum bicycle timings,
yellow timing for left turn, and through movements
will be calculated per the CA-MUTCD. Finally, based
on coordination factors, field observations, scenario
testing with Synchro, and our signal timing experience, we will propose signal timing groups and cycle lengths
for each of the synchronization periods.
2.5 Optimized Synchro Model & Implementation
Support: Based on the findings of the above tasks,
GTS will develop Synchro models inclusive of the
preferred set of improvements with optimized signal
timings for each of synchronization period. A table will be prepared to compare measures of effectiveness
(MOEs) between the existing conditions and the
proposed Synchro models. MOEs are anticipated
to include LOS, total travel time, total delay, fuel
consumption, and stops.

has assisted various cities with grant applications and grant management. We recently carried out 3 grant
applications for the HSIP program for the cities of
Buena Park and La Habra Heights to help upgrade
signal hardware, construct new signals, and upgrade
guardrail. We understand not only the grant writing
process, but equally important the scoring rubric that
is essential to ensure successful grant applications.
Our team has previously supported the City of Commerce
on successfully obtaining HSIP and ATP grants.
As part of our project delivery, we also support cities with grant management and dealing with the funding
agency requirements such as E-76 and others.

5. Attend Meetings and Prepare Presentation Materials
GTS often plans and attends council, commission, and
community meetings to solicit input and feedback on
projects. The scope of our services ranges from one-
on-one briefings to community at-large gatherings.
These meetings can take place at various milestones
during the life of the project. Meeting topics range from presenting initial findings to soliciting feedback from the community or council/comission.
GTS is prepared to assist with leading the meetings,
note taking, and support services which will include
coordination of meeting times and locations, hand-
outs, sign-in sheets, organization of facility details
(venue assumed to be provided by the City), and
meeting set-ups. We will also work with the City to
provide the notices and invitations to the meetings.
Sample Recent Relevant Projects:

Quality Assurance & Control Brief
GTS ensures project deliverables are free of errors,
easy to understand, and executed in line with client
expectations. Our established quality control process
builds on our experience to offer precision in delivery of our work. Our quality assurance/quality control
plan begins before the task order is assigned, during
scoping discussions. At this time, our project manager
will work with the City of Santa Clarita to define the
project tasks, establish roles and responsibilities
for project team members, identify communication
protocols, and identify success criteria for the project.
Subsequently, we develop a draft definition of required project tasks, deliverables, budget, and schedule.
Risk management, change management strategies,
and project communication plans are incorporated into
this planning process. Once these tasks have been
reviewed, modified, and adopted by the project team,
GTS will proceed with the project as planned, providing continuous support and regular communication with
the City.
For design work, our design plans will be field verified and reviewed by senior staff members during the
design.
Effective and Timely Communication
Whereby we expect on-going interaction with City
staff during each task order where progress can be
monitored. This could include weekly touchpoints to
discuss the project and ensure all parties are up to
date on project progress. We anticipate that informal
check-in meetings will occur regularly.
