About Us

Firm Profile

Established in 1996 in Ankeny, Iowa, Nilles Associates, Inc. has grown from a small land surveying firm to a full-service civil engineering, landscape architecture, and land surveying firm serving a wide range of private and public clients. We strive to make a positive difference to the clients and communities we serve, from the project planning stage through design, contract administration and construction.

Under the direction of John P. Nilles, PE & PLS, the company has become a leader in municipal engineering, land development, stormwater resources design, and master planning. We have provided innovative designs for projects large and small throughout the Des Moines metropolitan area and throughout the state of Iowa. As a smaller firm, we have stayed true to our roots, and continue to offer personalized survey and consultation services, no matter the size of the project.

Solid Foundation

The structure of Nilles Associates is founded on our solid team of professionally licensed and certified personnel. Our diverse experiences give us a wealth of expertise to draw from when working on challenging projects. We staff quality design professionals in the following areas:

  • Licensed Professional Engineers
  • Licensed Land Surveyors
  • Licensed Landscape Architects
  • Engineers in Training

Design Philosophy

Quality and teamwork are the cornerstones of our firm. Our ability to partner with our clients to work toward their goals allows us to develop long-term relationships with them. Professional partnerships make repeat business and referrals one of our greatest strengths.

Nilles Associates stays up-to-date on drafting, modeling, and surveying technologies, which allows our staff to quickly and efficiently meet the needs of our clients. Our firm continually invests in the latest tools and software, including CADD programs, GPS equipment, robotic total stations, hydrologic and water modeling systems, graphics programs, and 3D scanning. In addition, we have established and continue to update quality control standards for designs, drawings, and reports. Our work is our best advertisement.

We are not just satisfied with our past experiences. Instead we strive to find better, more effective and tested solutions. When necessary, we develop new partnerships that can help us find better solutions when developing new design practices. We have many relationships with electrical, mechanical, structural, geotechnical, architectural, and civil engineering firms with whom we consult for projects as needed.

Project Diversity and Innovation

Nilles Associates continues to develop and maintain a balanced portfolio of projects supported by a variety of clients including municipalities, schools, counties, state agencies, developers, architectural and engineering design firms, and other private-sector clients. No two projects are the same, and we work to find the most effective solution for each unique situation.
