  • Rachelle M. Lengermann
    Throughout our decade-long relationship, we’ve experienced Quality Testing and Engineering to be a valuable firm to have on our team, from project start to construction completion. Their timely and accurate geotechnical services allow us to understand the earth conditions prior to design.  During construction, their material testing services are thorough; whether they are testing soil compaction, concrete strengths, welds, or fireproofing thickness, they have the knowledge and expertise to verify the quality is to our high expectations. We have also utilized QTE’s environmental services on a long-term project.  Although the process was years long, it always felt like that project was a priority to them and they followed up frequently. In addition to having highly skilled staff, QTE is very competitive with their pricing, which allows us to produce a quality finished product within or below our client’s budget. I strongly recommend Quality Testing and Engineering for all of the services they have to offer before and throughout construction.

    Dear Mike, It has been a pleasure working with you over the past 7 years. Kamadulski Excavating has worked with QTE for as long as you have been in business and really enjoy the partnership! Having people like you is always an added benefit to our projects! We have enjoyed continued success with QTE while working at Gateway Commerce Center and many other sites in the St. Louis region. The on-site dirt is a very difficult material to work with. It takes a Team to move, place and compact it like we have done! We look forward to many more future projects with you.

  • Dear Mike, As we approach the completion of the subject 1,000,000 square foot distribution center in Edwardsville, IL. I would like to thank and compliment you on behalf of Hershey Foods Corporation for the engineering support and onsite monitoring, testing, and reporting performed by your company that has been a big part of making this project a success. Starting with our Request for a Proposal for a detailed Geotechnical Study in March 2003 and follow up soils design issues to support our May 2003 start date, your service and advice has been technically excellent, complete and timely in support of our aggressive construction schedule. Without question, you and your field personnel have supported our needs and made sure our interests were addressed and satisfied. Hershey Foods Corporation insists work be performed and verified to high standards, starting the first day of construction, while still maintaining schedule and budget. In today’s fast-track world, once the decision to proceed with a project is made, this requires a knowledgeable construction and engineering team be pulled together quickly to settle design issues as well as establishing an inspection program to control quality. Quality Testing and Engineering was a key player in the soils, concrete and paving design as well as site monitoring, testing, and reporting for these areas and site monitoring and reporting for structural steel. The knowledge, dedication, and professionalism of your design and field personnel as well as their willingness to work whatever hours it took in support of the construction effort is greatly appreciated.
