EDA has had great project success in the past and will continue to do so in the future. In fact, we sometimes receive unsolicited letters from clients or contractors related to a particular project. Feel free to review the below comments to get a feel for the quality of work that we do.

Dordt College - Stan Oordt - January 17, 2005
"This letter represents our relationship and history with Engineering Design Associates (EDA Inc.) of Sioux Center, Iowa.

EDA Inc. has been our principle electrical/mechanical engineer since 1990.  They engineered seven new construction projects, five remodel projects and numerous retrofit projects.  The largest project was the construction of our Campus Center in 2002.  This was a 12.5 million dollar project.

We have been satisfied with EDA’s engineering performance.  They are very thorough from building conception to commissioning.  They hold contractors accountable for work performed on major projects, while still working one on one with our maintenance department on smaller in-house projects.  EDA Inc. has also performed energy audits on many of our buildings with positive energy-saving results.

I would be happy to answer any questions you may have about the work EDA Inc. has done for us on these various projects."

Northwestern College - Scott Simmelink - January 10, 2005
"I write this letter on behalf of EDA Inc.

Northwestern College has had the distinct pleasure of working with EDA on a wide variety of projects on our campus over the last decade.  We have found their work, knowledge and expertise of electrical and mechanical systems to be exceptional.  Mr. Dean Pfeil, Mr. Norm TeKrony and Mr. Mike King and the EDA team are true professionals and they have the highest level of integrity and are up to date with the latest in technologies.  They are interested in our input and if we have a problem they are more then willing to come back to campus and assist us in resolving it.

Following is a list of some of our latest projects we had the pleasure working with EDA:

  • The Thea G. Korver Visual Arts Center
  • The DeWitt Theatre Art Center
  • Hospers Hall Bathroom Renovation
  • Van Peursem Science Wing Renovation

We look forward to working with EDA on the Learning Commons Project and more projects in the future.  If you have any questions please give me a call at your convenience."

Western Iowa Tech. Community College - Robert E. Dunker - January 7, 2005
"This letter of reference is being written to support the electrical and mechanical engineering design work that EDA, Inc. has done for Western Iowa Tech. Community College.  The College selected EDA, Inc. as the electrical and mechanical engineers for its first major building project in 1990.  Over the past 15 years EDA, Inc. has done all of the M & E engineering on two new buildings on the Sioux City campus, a new campus building in Cherokee, and a major expansion and remodel of the Denison campus building.  Also over the years, they have been involved in literally hundreds of remodel projects to upgrade and facilitate new and expanding infrastructure demands on the campus.

During this 15 year period of time, the College has never used another M & E engineering firm to do any of its work.  EDA, Inc. continues to provide quality services in a timely manner and at a fee that is reasonable as compared to the rest of the industry.  The firm operates with the utmost professionalism, honesty, and integrity, and all projects are completed on time within the allotted budget.  I have never once had doubts about their engineering decisions and ability to do the work we required at a fair price.

The decision to use EDA, Inc. as the electrical and mechanical engineers for Western Iowa Tech. Community College was a decision that I made early in my presidency and one that I have never looked back upon.  The College will continue to maintain our relationship with EDA, Inc. into the foreseeable future.  It is without any hesitation that I wholeheartedly recommend EDA, Inc. as a quality and reputable engineering and design firm.  Should you have any additional questions, I would be most happy to address them."

Sioux City Community School District - Larry Williams - April 10, 2003
"We have been very happy consumers of your services, and particularly are pleased with the fact that you are able to partner with architects in our area to positive outcomes in the design and renovation of buildings.

We anticipate a continued relationship with EDA, Inc."

Midwestern Mechanical, Inc. - Dwayne Klarenbeek - October 17, 2002
"While bidding a recent project we were reminded again how happy we are to work on an E.D.A. engineered plan. Not only are your plans clear and concise, but we know you’ve done the appropriate research to assure that the plans and specifications are complete and correct."

JESCO - Dennis Vonk – Branch Manager - April 19, 2002
"On behalf of everyone at JESCO, I want to thank you and your people for your professionalism and quality of work that comes from your office.

We bid on many projects through out the year and see many different engineer’s prints. By far your company has the most complete, concise, and quality prints we bid off of.

We have three people that bid on project here and they all rave about E.D.A. and the people there.

We believe that with the quality of your plans, the end customer gets the best job and a very competitive price because the guess work that can arise from an inferior set of plans is nonexistent."

Corning Community Schools - Gregg Fuerstenau - August 13, 2001
"This is a letter of recommendation and recognition for the exemplary service your firm provided the Corning Community School District.

E.D.A., Inc. provided the engineering and mechanical design for the replacement for the lighting and heating and cooling systems for our elementary building. This was a challenging renovation project from the standpoint our elementary facility was built around an open classroom concept that had to be entirely retrofitted for a geothermal heating and cooling system.

We were fortunate to have a company that has level of expertise and attention to detail working on this project. These fine attributes had a direct influence on getting the job done correctly and on time.

Dean, it is a pleasure to work with you and your fine staff. We are very satisfied with the work and I would highly recommend E.D.A., Inc. to any other school district considering a building and/or renovation project."

Kruck Plumbing & Heating Company Inc. - Stephen W. Kruck - August 2, 2001
"We are halfway through our first project with your firm and so far, the experience has been very positive. Your mechanical plan is very well-detailed including; well-designed plumbing riser diagrams and well layed-out equipment diagrams and schedules. The specification is clear, to-the-point and gives us the information needed to provide a quality product for the Owner.

We see a lot of engineering designs and most would not receive our letter of recommendation. We look forward to working with you on future projects."

Langel’s Plumbing & Heating - Sal Sciandra - May 15, 1998
"By experience, I have been on the contracting side of the HVAC and plumbing industry since 1965, and have been responsible for the estimating, purchasing, and management of mechanical contracts ranging upwards to $12,000,000.

Through the years I have had the privilege to work with many local, and nationally known engineering firms, but have recently been treated to working with E.D.A., Inc. on the Lawton Bronson School.

The drawings and specifications prepared by E.D.A. were by far, the clearest and best coordinated that I have ever worked with. And that, has resulted in a project that has run very smooth, and one that our mechanics are proud to have been involved with."

Western Iowa Tech Community College - Jerry Kingston - August 20, 1997
"Please accept this recommendation on behalf of Mr. Dean Pfeil.

Mr. Pfeil was employed as mechanical engineer at Western Iowa Tech Community College in 1991. Some of his accomplishments during this incumbency are the selection and supervision of installation of new boilers and chillers into two different buildings on our campus; managed the mechanical installation of a $700,000 lecture hall construction project; acted as WITCC’s representative in an $860,000 campus wide energy conservation audit, was the project engineer for a 4 million dollar construction linking two different campus buildings; and served as the project engineer of a 3.5 million dollar construction of a convention/educational center in Cherokee, Iowa.

In all of our associations, I have found, Dean, to be an effective communicator. His knowledge and expertise of construction engineering has been most fruitful for WITCC. I highly recommend E.D.A. Engineering and Mr. Dean Pfeil for building project mechanical projects."

Sergeant Bluff-Luton Community School District - Don Larson - November 9, 1992
"I want to thank you for the excellent work you and E.D.A., Inc. have provided for the Sgt. Bluff-Luton School system. There are many areas that come to mind where your company has provided the expertise, plans, and supervision during installation.

Our initial contact was in 1987. Your company converted our total electrical high school to natural gas, hydro-therm hot water boilers. Due to this switch our school system was able to reduce expenses by over $35,000 annually.

The second major project was construction of our new middle school 1989. E.D.A., Inc. was responsible for the mechanical contract. Your firm developed the design, supervised the installation and provided training to our custodial staff. We are very pleased with this system.

From time to time we have had questions about our mechanical systems and/or equipment malfunctions. In each instance you responded quickly and provided the answers to our questions. On more than one occasion, you took our concerns directly to the manufacturer. You have gone the extra mile to provide quality service for our school system.

I appreciate being able to call you about a problem and having you help me solve it.

Thanks again for all you have done for me."

Schroder Engineering, P.C. - Eldon L. Schroder - August 2, 1991
"The committee from WIT that went touring completed projects found one mechanical engineer’s work to be exceptional. The Owners like it, the maintenance crew liked it and our committee like it. This work is yours. I was impressed and pleased to find the equipment rooms well arranged and easy to keep clean, the equipment operation understood and easy to control and doing a good job.

There are very few mechanical engineers that I have been able to observe that truly were able to produce satisfactory work. They might have been hampered by budget but my impression has been that lack of skill is the most severe handicap that all of us face.

Congratulations of your good work, I wish you a long and prosperous future. The construction industry will be benefited by your good work and fine reputation."

Sergeant Bluff-Luton Community School District - Chuck Scott - May 31, 1989
"This is a letter of appreciation and recognition for the exemplary services your firm provided the Sergeant Bluff-Luton Community Schools.

Our school system has used your firm on two major projects within the past two years. Your firm provided the engineering and mechanical design for replacement of the heating system at the high school. The second project was designing the mechanical portion of our new 76,000 square foot middle school.

We are convinced that your leadership, attention to detail and honesty contributed directly to the successful completion of our projects. Throughout these past two years you have provided the guidance and expertise that we needed, while conveying the feeling that you worked for the Sergeant Bluff-Luton Board of Directors and our ideas/input were welcome.

Dean, it is a pleasure to work with you and the other members of the firm. We are completely satisfied with your workmanship and the finished product."

C.W. Suter & Son - E.Baker - June 1, 1989
"Our firm has been involved with E.D.A. Associates on several projects in the last three years.

During that period we have worked with E.D.A. on new construction, remodel, energy retrofit and energy studies.

We have found that their designs and drawings are very thorough with a lot of emphasis on economical operation and maintenance costs to the Owner.

We do not hesitate in recommending E.D.A. to serve your engineering needs."

Village Resorts - Ken Eckerman - June 5, 1989
"It is without reservation that I highly recommend to you the services of Dean Pfeil and E.D.A., Inc. I have worked very closely with them the past three years on better than a dozen projects, ranging in size from correcting a ventilation problem in one room, to dehumidification systems for swimming pools, to HVAC systems for entire hotel complexes. I have found their service to be exemplary, their designs to be state of the art, and their systems to be highly energy efficient.

Dean’s relationship with the sub-contractors who do the work is fantastic. His follow-through on each project right up through final check of the installation has saved me countless headaches.

Our company places extreme demands upon the people who do work for us. In every case E.D.A., has met the challenge of those demands and produced a solution to the problems we’ve thrown at them. There is no way that I would want to attempt another project that involved HVAC without their input!"
