The plan is enhanced by our computer-based accounting system. The accounting system is tied directly to
employee time sheets and billing information and is kept up to date on a weekly basis. This electronic system
reduces delays in getting the Project Manager budget information.
Using the Project Management Plan and the electronic accounting system, Tetra Tech’s budget management
program allows the project manager to efficiently oversee the project. These tools have been successfully utilized
on many design projects to maintain the project budget. We will work with the City during preparation of our
scope of services so that we have a full understanding of the project from inception. This allows us to develop a
clear and concise scope of services, which is thoroughly reviewed with our clients prior to execution. As such, the
need for unnecessary change orders is eliminated. Tetra Tech is proud of the fact that we are able to maintain
project budgets largely from defining a clear scope of services with our clients at inception. We encourage the
City to contact any of our clients to confirm our ability to maintain costs, as well as project schedules.
Cost Control
A second major factor Tetra Tech’s excellent performance record is the ability to provide thorough and complete
documents with which to estimate and control construction costs. Our personnel have many years of estimating
experience and closely scrutinize cost trends in the construction industry, carefully observe local job conditions,
and continuously update the database used in preparing estimates. Since Tetra Tech has completed numerous
stormwater improvement projects, we have a generous database of recent bid prices for a variety of bid items.
These prices help to establish a valid and reliable cost estimate, especially during master planning.
Our goal is to deliver successful, completed projects that fulfill the needs of our client. One of the lessons learned
in the firm’s years of experience is that good planning and good quality deliverables are the best insurance for
successful completion of a project. Because we pay close attention to each detail and make sure that all aspects
of the project are covered in the design or plan development, our clients are assured that when projects are
released for construction, budgets will be adhered to.
Tetra Tech's cost control methods focus on the assignment of key personnel who have established effective work
methods and who are fully experienced in all aspects of the project scope. Furthermore, the opinions and
comments of the City's project staff are encouraged throughout the project planning, permitting, design and
construction phases to ensure that all project objectives are satisfied. The key personnel for this project have
managed and prepared similar master plans. In addition, all project work is subject to technical and value
engineering reviews by senior staff members who are not directly involved in the project. This procedure includes
a formal periodic analysis of each project supported by our computer based project management system to
monitor and control project costs.
