“Since entering this role in January 2020, I’ve engaged with Clark Dietz on five project assignments. Clark Dietz has been very responsive and approachable, effectively managed their designs to the schedule and budget, exhibited a comprehensive understanding of our ever-evolving water design standards, efficiently coordinated other stakeholders, and ultimately delivered high-quality design documents. Clark Dietz has been a valuable contributor and more importantly, partner, in improving the success of our maturing Refresh program.”
“Our facility now has a highly efficient “green” wastewater treatment system which protects the environment with a reduced carbon footprint… Clark Dietz’s innovative, committed, and comprehensive approach combined with attentiveness to our needs and a high level of service and professionalism resulted in an optimal solution to balancing the needs of our community with the natural environment.”
“One of the primary benefits of working with Clark Dietz is the field knowledge that their designers possess. I have found continuously that project designs and project schedules are implemented without much complication. Their knowledge of materials, process, and IDOT standards is demonstrated in the product they provide. Their attention to detail and ability to resolve issues promptly and quickly avoids costly change orders…”
“My wastewater operations group was very impressed that we did not have any (zero) overflows upstream of the new lift station and relief sewer from Juan Solomon Park (Belmont North Relief Sewer Project) this past weekend. Historically a 3” rain event would have resulted in numerous overflows in the area. This is further pleasing given the new STEP projects that have also been added to the system in the area.”
“Clark Dietz not only provided an innovative design for our project, but they also structured their project plan around our unique needs. Their understanding of our vision was critical to the success of the project.”
“My experience with Clark Dietz has been exceptional. Over the past few years, we’ve partnered with them on various utility projects, most recently, a water main replacement for one of our older neighborhoods. Throughout the process, Clark Dietz worked closely with our team, from the initial design phase all the way through construction. Their collaborative approach and technical expertise made the project run smoothly, ensuring that all challenges were addressed efficiently and professionally.”
“Throughout the duration of the project, Clark Dietz consistently went above and beyond to ensure that the needs of our community were not only met but exceeded. They worked closely with us to understand our long-term goals and provided tailored solutions that enhanced the project’s impact on the community. Their proactive communication, responsiveness to our concerns, and dedication to finding innovative solutions created a seamless experience for all involved.”
“Beyond the emergency response, the team delivered a long-term, permanent solution involving a 20-foot-diameter concrete secant shaft, hand tunneling to reconnect the system, and lining of the existing outfall, all while preserving the parkland and minimizing disruption to the community. Their proactive communication, unified coordination, and dedication to protecting public safety made this project a success.”
“I have worked with Clark Dietz on numerous projects since coming to work in Champaign in 1997. During my time as the City Engineer in the Champaign Public Works Department, Clark Dietz was our preferred design and construction engineering consultant for street and drainage. During my tenure as Senior Engineer at Illinois American Water Company (ILAW), which started in 2008, Clark Dietz provided design and construction engineering services on several water distribution system improvements for which I was directly responsible. From development of plans to on-site project representation for water main improvements, as well as the construction of new administration and chemical feed buildings at our treatment facilities, the Clark Dietz team brought expertise, experience, and professionalism to ensure that every improvement was built to ILAW standards.”
“Clark Dietz has performed design and construction inspection services for us on multiple INDOT-administered projects and has helped us every step of the way in keeping up with the rigorous INDOT administrative requirements to maintain schedules.”
“Clark Dietz produced results beyond our expectations. The solution not only provided substantial cost savings, but the facility now has a highly efficient “green” wastewater treatment system which protects the environment with a reduced carbon footprint and reduced nutrient loading on the Fox River Watershed. The Northwest Regional Water Reclamation Facility (NWRWRF) can efficiently and responsibly meet the needs of residents well into the future.”
“The Schroeder Hall Rehabilitation project was undertaken primarily as a vehicle to improve the mechanical and electrical infrastructure of Schroeder Hall, one of the older, yet heavily used classroom and office buildings on the Illinois State University campus. Since the building remained partially occupied during both phases of work, the University also endured less disruption to those who remained in the building, having construction activity occur for less than 12 months as opposed to 18 months. The project exceeded the expectations of the University in both design and construction. Schroeder Hall is a shining example of how well a construction project can be executed.”
“Over the course of our project, it changed multiple times in scope and direction. Throughout the process, Clark Dietz was accessible, patient and provided us with
quality work for a fair price. Because of their experience doing these types of projects, they were able to ask the right questions of the vendors to ensure that all tasks were being done properly. We would recommend their services to others looking for assistance in design, bids, and installation oversight.”
“The Clark Dietz team is doing a great job in Elmhurst this year. They have been ‘on-it’ managing all the construction, and this extends to the design group as well. You have been rockstars! We’ve asked more of your team’s leadership this year, and it has been delivered, as well. The cherry on top is you keep us moving at the pace we want to go. I don’t have to ask for things; they are just ready. We’ve asked a lot of Clark Dietz, and I’m happy to report you all have brought it. I feel like in our business, we don’t hear this enough, so thank you from us all here at the City!”
“The expertise provided by Clark Dietz both in the design and management of the City of Champaign’s project was outstanding. City Staff had very high expectations during the project, and they demanded prompt resolution to any issues that arose. Clark Dietz responded to the requests of City Staff time and time again. Their attentiveness was greatly appreciated, and I would certainly recommend them for any future City projects.”
“Clark Dietz’s professionalism, teamwork, ingenuity, and collaboration brought improvements well beyond the original goal of updating the fence. Their genuine interest in listening to our needs and vision to optimize the result brought our entire community a public space of which they can be proud, and encouraged more visitors to experience our beach, our lakefront, our business district, and the other amenities Port Washington has to offer.”
“Throughout many years of working together, the City of New Albany and Clark Dietz have developed an exceptional relationship. Whenever a project has a challenging deadline—where it sometimes feels it may be impossible to meet—New Albany calls upon Clark Dietz and their incredible team. Without fail, Clark Dietz delivers a product that is exceptional, within the parameters established by the City, and within the timelines given. As a customer, I know we are not the easiest to work with; however, Clark Dietz continually produces results that far exceed our expectations. Without hesitation, I would hire Clark Dietz for any project, and I would recommend them to anyone in need of exceptional professional engineering services but especially to those that need help mitigating difficult circumstances.”
“While working on the Brown’s Station Way Corridor Study for the Town of Clarksville, Clark Dietz proved time and time again their ability to meet our needs by collaborating with staff, engaging the public, and implementing feedback from all parties to create a pragmatic study that should prove routine to carry out and bring to construction. Clark Dietz takes ownership of their product and will continue to act as lead partners throughout the entire process. They’ve proven to be an invaluable asset and the Town of Clarksville would not hesitate to hire them again.”
“After the completion of the Village’s First Street Drainage Project, I’ve had a number of residents go out of their way to express their appreciation for the Village tackling a drainage project in their neighborhood that has eliminated flooding and standing water in their yards that has been an issue for many years. One gentleman in particular shared that he lives in his childhood home and that the yard has always flooded and usually had standing water for long periods of time. His yard now drains, even after a heavy rain. The Village worked together as a team with Clark Dietz to make this project a success story. Not all projects get much attention, but this one has made a lot of homeowners very happy.”
“The Village of Richton Park has been fortunate to have Clark Dietz represent the Village overseeing the Poplar Bike Trail Project. This 1.6-million-dollar project enhanced the existing path and connected the Old Plank Trail in Matteson. The coordination with the two communities, CN Railroad, and IDOT was seamless. Furthermore, the Phase 1 and Phase 2 were spot on. The Village of Richton Park could not express enough the level of gratitude to Clark Dietz in assisting the Village in getting this project funded through three different grants enabling the Village to have a net zero out of pocket expense.”
“When larger planning and design projects come up, [the Clark Dietz team is] flexible and creative with their approach and understand our financial limitations. I feel comfortable working with Clark Dietz on any size project knowing they have the City’s best interest in mind.”
“FCWRD was pleased to have worked with CD-CM services on the major sewer relocation work required by the Tollway (I294) Expansion Project in the District. This work required a high degree of partnering between Design, Construction, and Operations, and CD-CM services were always helpful, competent and professional, making this project a success.”
“Throughout the project [Lost Bridge Force Main], Clark Dietz demonstrated professionalism, collaboration, and technical expertise. Their partnership with the District helped ensure the project was delivered efficiently, safely, and with minimal impact to the surrounding community and environment. The project is an excellent example of engineering that meets critical community needs through innovation and teamwork. The Sanitary District of Decatur is proud to have worked with Clark Dietz on this successful and impactful project.”
“The projects that you have undertaken, including the many detention ponds that have been constructed in the Village, have truly helped the Bayside community. Thank you for all of your hard work.”
Thomas on Tonia Westphal, PE, LEED AP: “The City of Merrill has always been impressed with the outstanding job she has done for our organization. Technically, the work was excellent. From a public relations standpoint, she does a great job as “front person” for our projects and improvements. She knows engineering and does it well. Her public relation skills are second to none. I heartily recommend her for any position or project in which she is interested.”
“Clark Dietz recently designed and oversaw the remodeling of the electrical, mechanical, ventilation and communications of our former Science building into a new Business School. This was a 36,000 square foot building constructed in 1954. They did an excellent job throughout the entire planning, designing, and construction phases. As a university project manager, I have worked with many engineering firms and consider Clark Dietz as one of the premier firms in Illinois. I find them to be thorough and professional in every way. I certainly recommend their services for any future project.”
“Clark Dietz exceeded our goals for this project and minimized disruption to both our WWTP operators and the City. The new filters are clean, efficient, easy to maintain, and produce excellent water quality. The forward-looking design and layout of our filtration system meet our current needs and will also be easy to expand as our community continues to grow. We are happy to have used new technology to make our space more efficient and the treatment environment a better place for our operators to work.”
