CONSTRUCTION ADMINISTRATION

Trotter and Associates, Inc. provides construction engineering services for all aspects of public improvements from roadway to wastewater treatment facility construction. We also provide inspection services to certify that public improvements completed by private developers are in accordance with the municipalities ordinances. Our construction phase services include:


  • Construction Management
  • Construction Inspection
  • Resident Engineering
  • Construction Layout


TAI’s approach to construction phase services is different from most of our competitors. Our design phase team is our construction phase team. As a result, our design team can anticipate construction issues in the design phase as well as understand the issues that do arise. We prefer to assign one of the design team members as the resident engineer (RE) on the project. Therefore, our resident engineer has the background and knowledge of the design intent to assist in making any adjustments required.


Furthermore, the project manager and project engineer remain the same throughout the project and attend the weekly construction meetings. Through superior design and consistency in our construction phase team, we have successfully kept our change order rate below 1.5% compared to the industry average of 7%.


During construction, communication is one of the most important elements required for a successful project. TAI’s staff makes it a point to be in touch with our clients throughout the construction process, either in conversation or written form depending on the project’s and client’s needs. Through continuous communication with our clients we are able to resolve issues quickly. If there are any clarifications to the contract documents, the client needs to know what those clarifications are and how they will ultimately be resolved.


To keep all the stakeholders informed during the construction process, our staff typically assembles a monthly construction management report that includes:


  • Construction Progress Summary
  • Contractor’s Pay Request Summaries
  • Resident Engineers Daily Reports
  • Shop Drawing Log
  • Executed Change Orders
  • Request for Change Orders
  • Progress photographs


Trotter and Associates, Inc. is not only recognized for our design capabilities, but is also known throughout the industry for our impartial interpretation of the contract documents. This approach increases the number of contractors willing to bid on our projects.


The contractors know that our firm is thorough and that our plans are crystal clear without the ambiguity or “implied” work shown by other firms. As a result, contractors do not place a factor of safety on their bids. Additionally, instead of receiving only a few bids, TAI projects consistently receive more the seven bids. As a result, the Owner is ensured that he received a competitive price for his project. The competitive price in the bidding process and lower change order rate translates to a much higher value to the Owner for the product.

By Village of Roselle – Jerry A. Botterman STP BNR Upgrade Project March 2, 2026
The Village of Roselle has begun construction of the Biological Nutrient Removal Upgrade Project at its Jerry A. Botterman Sanitary Treatment Plant. The project incorporates recommendations outlined in the Village’s 2022 Wastewater Facility Plan, which ensure compliance with future wastewater effluent regulations and improve the facility's reliability by replacing aging equipment. The improvements include converting the existing Oxidation Ditch to a Biological Nutrient Removal process for phosphorus and nitrogen removal, construction of a Chemical Feed Building to allow Alum to be used to aid in the phosphorus removal process, and replacement of the Influent Screens and Final Clarifier equipment. John Burns Construction Company began construction of the Chemical Feed Building in the fall of 2025, work is progressing as scheduled. Over the next year, Trotter and Associates will continue to work closely with the Village and John Burns Construction Company to help ensure the project’s success.

The $1.36 million Village of Algonquin Braewood Lift Station Rehabilitation project is complete. Delivered in collaboration with the Village of Algonquin and Dahme Mechanical Industries, Inc., the project was completed on schedule and within 1.4% of the original construction contract amount. Following a 2022 condition assessment by Trotter and Associates, Inc. (TAI), improvements were identified to increase lift station and force main capacity. The force main replacement was completed in 2024, followed by lift station rehabilitation and system integration. Improvements included upsized pumps, VFDs, and piping; replacement of the grinder, flow meter, and odor-control equipment; electrical and HVAC upgrades; and connection to the new 16-inch force main. Station capacity increased from 1,500 GPM to 5,000 GPM, supporting future Village development.

The City of Saint Charles has completed Sequence #1 of the Ohio Avenue and Kautz Road Raw Water Main Installation Project, advancing critical water infrastructure improvements. The work included installing a new raw water main between Well No. 8 and the future Well No. 14, along with other key infrastructure components and roadway restoration. Most of the water main was installed using horizontal directional drilling to minimize surface impacts and limit disruption, and hydrants were installed by open-cutting. Trotter and Associates supported the City by securing EPA funding, designing the water main alignment, assisting with the bidding process, and observing construction in cooperation with City staff.
