Building relationships with our clients...

"SCS Engineers called upon SIEREX DESIGN & CONSTRUCTION to support an emergency response and recovery project for a partial building collapse of a US government building in Arlington, Nebraska.  The partial collapse, caused by an adjacent building demolition, required immediate response to buttress the exterior wall to allow retrieval of accountable items by government officials.  Morgan and Foster were second to none and provided timely support under the direction of the onsite structural engineer to stabilize and secure the building.  I would strongly recommend SIEREX to anyone who desires a responsive, thoughtful, and methodical contractor who understands engineering and knows how to work alongside and with engineers."

Mike Miller
Vice President, SCS Engineers



"SIEREX was a great selection for our office fit-up project. Foster and Morgan brought incredible value, were willing to work cooperatively through a few difficult situations, and did their very best to maintain a restricted schedule—all while maintaining a positive and friendly demeanor. I would absolutely work with SIEREX again in the future and would recommend the company to our clients as well."

"SIEREX designed and built our three-car clear-story garage with a mezzanine workshop. This project started with a few pictures and the direction to “build me that.” Morgan embraced the idea and worked with us to fine tune the design to the existing slab. We looked at a variety of options, and developed a sketchup model for each. SIEREX built a solid, useful, and attractive space for us, while maintaining a safe worksite to ensure our children’s well-being. SIEREX also addressed a drainage issue that was not in the original scope. We appreciated SIEREX's enthusiastic and friendly approach. They have a terrific attention to detail while maintaining a holistic overall vision of the finished product. We would wholeheartedly recommend SIEREX to anyone looking to design and build long-lasting and valuable structures"
