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 Algonquin’s Water Treatment Plants No. 1 and No. 2 Aerators and Roof Replacement project is nearing completion. With the new aerators operational, the Village will more effectively oxidize contaminants, enabling the facility to continue providing high-quality water to the community.  The new aerators also enhanced the facilities' capabilities and minimized objectionable odors. WTP No. 1 is a vital facility and cannot be taken out of service. This required careful planning and communication among the team to ensure uninterrupted operations. Close coordination between the Village of Algonquin, Trotter and Associates, and Keno and Sons Construction Company enabled the project to be successfully sequenced and completed within budget.

The City of Woodstock is continuing to enhance its aging infrastructure through its Gould Street Water Main Replacement project. Once complete, the project will have replaced and upsized a quarter mile of water main from 4” to 8”, which reinforces the system's operation and longevity. Various storm and sanitary sewer point repairs were also completed to ensure all underground improvements within the roadway were completed before resurfacing and reconstruction of the various roadways.

Phase I Improvements at the City of Woodstock’s South Wastewater Treatment Plant are progressing on schedule, with the chemical phosphorus removal system expected to come online this fall, marking the first significant milestone of the project. The strong performance of Manusos General Contracting and their team of subcontractors has been key to staying on track. Manusos has led structural concrete work and continues to manage overall construction efforts. RV Builders completed the construction of the ground face masonry block building shell, while Dahme Mechanical Industries installed under-slab plumbing and process piping. Associated Electrical Contractors has completed under-slab electrical work, and Jim Burke Excavating handled earthwork and installation of underground site utilities, including preparation for the new ring road. Upcoming work will focus on the chemical building systems, rehabilitation of the aerobic digesters, and improvements to the oxidation ditch. The project remains on track for final completion in summer 2026. Trotter and Associates, Inc. is proud to support the City of Woodstock with engineering solutions that advance water quality and infrastructure reliability for the community.

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.
