Subject: Proposal for Engineering Support Services During Construction for Industrial Wastewater Treatment Facility Project
Dear Patrick Dobbins:
We are pleased to provide this proposal for engineering support services during construction (ESDC) for the Industrial Wastewater Treatment Facility (IWTF) project. Included in this proposal are the following sections:
1. General Information, providing general information and primary point of contact
2. Project Understanding and Approach, describing project background and objectives
3. Scope of Work, defining specific work elements
4. Fee Proposal, quantifying our anticipated level of effort Our proposal demonstrates our thorough understanding of your project goals and offers a comprehensive approach and dedicated project team for its successful completion. 1 General Information
The Dudek team presented within this proposal has the resources to perform the work required for each of the Project Tasks, as included in the Project Scope of Work. Tasks to be completed by subcontractors are also defined in the Scope of Work. Subcontractors are the same as utilized during the design phases of the project. The primary point of contact for proposal and project correspondence is Kate Palmer, P.E., Principal Engineer, available at 760.479.4160 and [email protected].
2 Project Understanding and Approach
The final design bid documents were completed by the Dudek team and advertised for bidding for the City of Gonzales (City) Industrial Wastewater Treatment Facility. Bidding of the project was completed on February 26, 2025.

WASTEWATER TREATMENT FACILITY
FEBRRUARY 2025 2
Following review of the bids and confirmation of the lowest responsive and qualified contractor, construction is expected to start in June 2025 (assumes NTP March 2025).
As Engineer of Record (EOR), Dudek understands the full scope of project construction activities for the project.
Supply chain issues may continue to impact the ability of the contractor to successfully complete construction within the anticipated contract duration. To assist in successful completion of the contract within the contract duration, Dudek will work with the City to prioritize submittal review of materials with the longest lead times, thereby allowing those to be ordered as soon as possible. These specific topics and any other critical path items may be discussed at the kick-off meeting to collaborate on potential solutions and mitigate potential delays. 3 Scope of Services
Dudek will follow the detailed scope of work tasks outlined below. In preparation, Dudek assumes that the City will employ the services of a construction management (CM) team that will provide field staff to the construction site daily, and thus we have not included scope/hours for a daily onsite presence. Use of a CM will assure constant communication between the contractor, the City and EOR, as well as assure smoother completion of construction activities. Dudek assumes that environmental monitoring services (i.e., cultural monitoring) will be provided under separate contract.
In accordance with the City’s request, Dudek proposes to provide the following services:
