Engineering Services

Ruthrauff | Sauer maintains an in-house engineering staff primarily to accommodate design/build projects for which we provide both design and construction services. Our engineers and designers are also available as a troubleshooting and value engineering resource for non-design-build work or existing installations. Ruthrauff | Sauer's extensive resume of design/build work includes both HVAC and plumbing projects for a wide variety of commercial, industrial and institutional clients. Our designs range in complexity from packaged rooftop air conditioning units with simple duct layouts to central chilled water and steam plants serving multiple air handling systems. Daily interaction between our engineering staff and our own construction forces makes us better designers and results inĀ better-engineered systems for our clients. When you're looking for the best-engineered building at the fairest possible price, Ruthrauff | Sauer is the single source for all of your HVAC and Plumbing needs. Talk to us at the development stage and maximize your potential for a more cost-effective, shorter duration project. Notable Design Build Projects
