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.

The Village of Barrington Hills has kicked off its 2025 Road Program, which includes HMA resurfacing along three miles of roadway and patching and striping on five miles of various roadways within the Village. With the initial removal completed, crews have begun placing reflective crack control fabric along the milled roadway. Utilization of this fabric on resurfacing projects reduces reflective cracking from the underlying pavement. It acts as a moisture barrier, all of which assist in extending the service life of the roadway. The final HMA surface placement along Spring Creek Road and Buckley Road, patching of various streets, and striping are expected to be completed in the coming months.

The Village of Algonquin, Trotter and Associates, Inc., and Manusos General Contracting are excited to be moving into the construction phase of the WWTF Biosolids Handling Improvements project. With anticipated long lead times for equipment, the project team is working diligently to process submittals to ensure installation of the two decanter centrifuges can begin in the Spring of 2026 as planned. Upon completion of the project, the Village will have met its goal of upgrading the sludge dewatering operation to maintain processing current demands and allow for future development.

Concrete repairs are vital for preserving the integrity of existing structures and enhancing their service life. This was the main objective for the Structural Repairs Project at Fox River Water Reclamation District’s North and West facilities. To meet this objective, the Trotter structural team evaluated numerous buildings, tanks, and components at both facilities to develop a comprehensive repair plan. Repairs ranged from minor crack injection to full-depth concrete repairs, masonry repairs, and improvements to aluminum stairs and guardrails. Dahme Mechanical Industries (DMI) and its team of subcontractors, Manusos General Contracting, Bulley & Andrews, Alliance Concrete Sawing and Drilling, and A. Horn Inc., are wrapping up the final stages of the project. The remaining scope of work includes regrouting a Final Clarifier and extensive rehabilitation of a concrete structure that dates to the early 1950s. In addition to the structural components of this project, existing stop plates at the West Facility’s Chlorine Contact Tank were replaced with slide gates, improving operational efficiencies for District Staff. The DMI team effectively and efficiently installed all fourteen gates within a week, allowing District Staff to resume maintenance on their facilities in preparation for the disinfection season.

In 2022, Trotter and Associates, Inc. completed an assessment of the Village of Algonquin’s Braewood Lift Station. The primary improvements focused on increasing the station’s capacity to handle the rapid growth in both the Braewood Lift Station service area and the upstream Grand Reserve Lift Station service area. With the increased capacity of the station, the velocity through the existing 10-inch force main exceeded allowable limits. To address this, a 16-inch force main was included in the design, which was constructed in 2024.  With the force main constructed, the station rehabilitation has commenced. Work within the station includes upsizing the piping and pumps, replacing the grinder, and improving both the electrical and HVAC systems. Upon completion of the work, the pumping capacity of the station will be increased from 1,500 gallons per minute (GPM) to 5,000 GPM, allowing the Village to meet both current and future development demands.
