Whether it is Design-Build, Design-Assist, or Plan-and-Spec, Riddleberger has the experience and resources to take your project from initial design to project completion. In each of these scenarios we bring a team approach focused on a cost effective, high quality, and safe project.


Preconstruction and Engineering

We can benefit your project before construction starts with our preconstruction services. During the initial design phase, we can provide valuable input on market conditions, budget, constructability, and schedule. We’ll leverage the latest construction technology, including estimating software and building information modeling (BIM), to review various design scenarios to ensure your project stays on track.


Building Information Modeling

Building Information Modeling (BIM) has become an integral part of our project delivery. While BIM does identify and solve issues virtually prior to being onsite, we have taken the process beyond this typical coordination and clash detection, as it now drives our prefabrication initiative.

Offsite Construction


With over 100,000 square feet of fabrication facilities, Riddleberger has invested heavily in this initiative. Our strong focus on prefabrication will benefit your project in many ways:

  • Improved Safety – our controlled shop environment is much safer than a construction site
  • Higher Quality Control – the controlled shop environment leads to a higher quality product
  • Improved Schedule – we are able to prefabricate vast portions of systems prior to building erection, minimize time lost to inclement weather, and improve field productivity

Onsite Construction

Once onsite, Riddleberger has the resources to maintain a safe, cost effective, high quality, and on-schedule project. We look forward to putting “Our Experience At Your Service”!
