APPROACH AND METHODOLOGY
APPROACH
The TJKM Team provides the full range of traffic engineering and transportation planning capabilities necessary to address the many and varied
requirements of this contract. Our approach to providing the required services is focused on adequately responding to the following key points:
• Ensure a Staffing Capacity with the Necessary Range of Expertise and Experience. TJKM is a leader in providing services in the fields of
traffic engineering, transportation planning, operational analysis, and ITS. The experience offered by TJKM includes numerous local examples of traffic engineering relevant to this contract. Our proposed team has demonstrated the ability to successfully manage both
large and small projects and resolve issues through a proactive management process throughout California and United States. TJKM
operations include a full range of transportation engineers and planners with expertise necessary to meet the City’s changing needs on
a day-to-day basis.
• Provide Experienced Project Manager and Task Leaders. The TJKM Project Team is comprised of highly qualified individuals with
extensive project management experience. Ms. Jariwala, PE, TE has over 26 years of comprehensive transportation planning and
engineering and grant writing experience and will serve as overall TJKM Project Manager, providing a single point of contact for the City.
Our proposed team also includes Category Leads/Task Leads with extensive experience in their field of expertise. Our proposed team
has worked together on numerous projects and successfully delivered the projects on time and within budget.
• Understand City’s Policies and Standards. Our ongoing involvement in the region's transportation and engineering projects, combined
with our extensive national experience in conducting traffic studies and design work, gives the TJKM Team the knowledge and in-depth
experience to efficiently complete task assignments. Our team members are familiar with the City’s Policies and Standards.
• Ensure Responsiveness to both City Needs and Project Issues. With our available resources, TJKM can provide the level of
responsiveness needed by the City. Our staff is adept at meeting client needs and being very responsive. The TJKM Team will develop
an individualized approach to each assignment, specifically designed to the unique project issues and requirements. This, combined with
an active project management and team-oriented approach, will ensure the delivery of timely, high-quality assignments.
• Ensure Availability and Interest in the Projects. TJKM has dedicated traffic engineers who will be available to meet the city needs in
being responsive and providing timely quality products. Our staff is adept at taking ownership in the projects they work on. This positive
attitude provides a very high level of interest and assures the City a quality work product.
• A Sound Approach. The TJKM project management approach has been consistently demonstrated to be effective through the success
of past and current projects to be an effective manner in which to conduct On-Call Service Contracts. Our approach to project
management is characterized by three basic responsibilities:
1. Ensure that each project assignment is completed on time
2. Ensure that the assignment is completed within budget
3. Ensure that the assignment is completed with a high degree of quality and innovation
PROPOSED METHODOLOGIES, TECHNIQUES, AND PROCEDURES
On-Call services are provided to agencies to fill the potential gaps created by a shortage of staff or a project or task which requires specific
expertise and experience. TJKM strongly believes in working as an extension of your staff and dedicating our multi-disciplinary staff to meet
all the requirements for the On-Call Services. TJKM has assigned an Overall On-Call Project Manager who will be the City’s main point of
contact for all high-level communication. Based on each request that comes in from the agency, TJKM will assign the respective Category
Lead and applicable Task Leads to assist the project manager for any given task order or work request. TJKM will setup a project kick-off
meeting to discuss goals and objectives and move forward the request. The Category Lead will be responsible for overseeing that Task Leads
and support staff complete all work within the agreed upon schedule and budget. This process will ensure the city gets each task order
completed in timely manner and multiple requests can be simultaneously accommodated by TJKM.
RESPONSE TO TASK ORDERS
The TJKM Project Management Plan that will be used on these projects is based on proven management, lessons learned, and administrative
systems developed to enhance communication among the City of Diamond Bar the TJKM Project Manager and team members, and other
affected agencies. This management approach has been used successfully on numerous projects throughout California. The TJKM Project
Management Plan has the following elements:
• Work Plan: It is a TJKM policy to prepare a Work Plan for all projects, large and small. Upon receipt of a Notice-to-Proceed, we will
prepare, in consultation with the City and other local jurisdictions, an overall project work plan that includes detailed work elements for
each team specialty. A TJKM work plan typically includes definition of the project purpose; task objectives; scope of services; staffing;
coordination requirements; deliverables; budget; schedule; and monitoring and reporting procedures.
Coordination and Communication: Frequent and effective communication between the City, other local jurisdictions, and the TJKM
Team is needed to maintain the schedule and ensure a quality product. The key to our success is an integrated team approach. Our goal
is "no surprises" and a partnership that has common understanding and expectations every step of the way. Ms. Jariwala will maintain
close communication with the City’s Project Manager by personal contact, telephone, written communications, and meetings. Our
Project Manager strongly believes in the necessity and benefit of scheduled monthly progress meetings. Ms. Jariwala and other key
Proposal for Professional On-Call Traffic and Transportation Engineering Services
City of Diamond Bar
| 8
team members will meet with the City’s Project Manager monthly to discuss project issues, status, schedule, budget, and invoicing items.
This will ensure that our "no surprises" goal is maintained, and the City is thoroughly aware of all aspects of the project. The TJKM Team
will maintain regular contact with City staff to ensure clear communication on project tasks, products, meetings, and schedule.
• Cost Control: Control of project costs will be accomplished by monitoring on a task level basis. This detailed task level will roll up into
milestone summaries and a project summary. Our cost accounting system is a "live" database that the project manager can access to
determine the financial status of the project at any time. Cost control reporting to TJKM’s Project Manager will be implemented through the invoicing process. Progress reports will also be included to relay information on project progress and critical issues.
• Schedule Control: Establishing a schedule that meets the project objectives is relatively easy. Maintaining this schedule during changing
project priorities, unforeseen conditions, public consensus building, etc., is a challenge. The project work scope will be broken down by
function and separated into defined tasks. Tasks will be linked logically and will be sufficiently detailed to allow for realistic representation
of the project. Project progress will also be monitored by percent complete for each task.
• Quality Control: TJKM’s Quality Assurance Procedures are utilized throughout the life of the Project. Quality Control starts at the
proposal and scope definition stage and continues through the completion of all assignments. To assure that errors, omissions and
ambiguities in submittals and drawings are limited to an absolute minimum, the responsibilities for technical review, peer
review/coordination checking, and technical audit functions are assigned to the appropriate TJKM Team members. TJKM’s approach
integrates the work of our subconsultants into the quality control system using established procedures and our peer
review/independent checking capability augmented with technical audits.
METHODOLOGY/RELEVANT EXPERTISE
A. TRAFFIC ENGINEERING/STUDIES
Review Traffic Impact Studies and Traffic Sections of Environmental Documents
TJKM brings extensive experience in delivering Traffic Impact Analyses (TIAs), having successfully
completed over 3,000 studies for projects ranging from small standalone uses (e.g., gas stations and
coffee shops) to large-scale residential and mixed-use developments. Our team supports both public
agencies and private clients in evaluating transportation impacts across a full spectrum of land uses,
including residential, retail, office, institutional, industrial, governmental, and recreational. We provide
comprehensive TIA services, including existing and future conditions analysis, identification of
transportation system deficiencies, and development of feasible and cost-effective mitigation measures. Our team prepares conceptual and
schematic improvement plans, as well as Plans, Specifications, and Estimates (PS&E), to support implementation. We are highly experienced
in analyzing Level of Service (LOS) and Vehicle Miles Traveled (VMT) in compliance with current regulatory requirements.
Our approach emphasizes innovative, yet practical solutions tailored to each project’s context. Recommendations may include signal timing
modifications, intersection improvements, Intelligent Transportation Systems (ITS) applications, multimodal enhancements, and, where warranted, major roadway expansions. All recommendations are developed with careful consideration of agency policies, funding
constraints, and the client’s goals for economic development and sustainable growth. TJKM is recognized throughout California, Texas, and
