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.

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.

Construction of Fox Metro Water Reclamation District’s North WWTP Bar Screen Replacement project has begun. Trotter and Associates is assisting the District with construction engineering services throughout the project, including close coordination and collaboration with the District's design engineer. The existing bar screen operation utilizes three mechanical bar screens, which date back to 1989 when the District operated as the Aurora Sanitary District. The three existing screens are being replaced as part of the project, and a fourth is being integrated into the process. The contractor recently completed the erection of the building's additional outer shell. To facilitate the building addition, the contractor relocated several site utilities, including the relocation of the 72” overflow. With the project still in its infancy, construction will continue through 2025.

The Village of Fox Lake recently completed its 2024 Roadway Improvement project that improved a half mile of Longwood Drive and Wildwood Drive. Rehabilitating these roadways included using Full-Depth Reclamation with Cement, a sustainable construction method. This method pulverizes the existing pavement section and mixes cement, providing a more substantial base for the new pavement section. Grant Township maintains a section of Longwood Drive and two other roadways east of the work being completed. To minimize public impacts and provide a comprehensive improvement to residents, the Township resurfaced a half mile of its roadways in conjunction with the Village. Trotter and Associates provided design and construction engineering services for the Village and the Township.

Glenbard Wastewater Authority recently completed replacing the aging asphalt parking lot at its main office. To meet current needs, the lot was expanded from seven spaces to sixteen, including accessible parking. With the East Branch DuPage River directly downstream of the site, permeable pavers were utilized instead of asphalt. The use of these pavers not only reduces the amount of stormwater runoff but also improves the quality through natural filtering. Trotter and Associates assisted the Authority throughout the entire life cycle of this project.
