ConX Chassis Based Modular®: revolutionizing the building industry

ConXtech Inc. is a construction technology company based in Pleasanton and Hayward, CA. The company has developed ConX®, a revolutionary  Chassis Based Modular structural steel building system which enables rapid delivery of robust, cost efficient and sustainable structures.

Alternative to traditional building methods

ConXtech’s founder Robert J. Simmons had long envisioned a concept that would streamline traditional building processes. He wanted to create a building system that would enable mass customization of high quality buildings that would be faster and more cost effective than conventional wood, concrete or steel framed methods.

The ConX System was conceived on the premise that quality is the key to any endeavor’s success. “Integrity, efficiency, and exceeding client expectations are goals that influence everything we do. We strive to be efficient in our use of materials, energy, time and human resources.” states Simmons. His innovations include four lower and locking steel connections and numerous manufacturing technologies, resulting in 140+ patents to date.

Systemized approach to building processes

The company sells a standard set of manufactured Lower and Locking™ connectors and building components, enabling the mass-customization of a precise structural building frame or chassis to which other factory manufactured building modules can be added. When assembled into multi-bay, multi-story structures, the patented connection technology delivers a brace-free grid of Special Moment Frames (SMF), ideal for commercial, healthcare, military, high-density residential, data center, and educational applications as well as industrial structures for the oil and gas industry.

The ConX System reduces time and overall project costs when compared to conventional structures and brings a systemic change to the building process, enabling owners and developers to predictably build Faster, Better, Safer and Greener®.

ConXtech licenses its fabrication technologies, methods and processes to a growing network of certified fabricators and erectors.

Codified and Certified Technology

The ConXL™ special moment frame connection is codified  by the American Institute of Steel Construction (AISC) and published in AISC 358-10 Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications for use by structural engineers worldwide. It is also approved by the Office of Statewide Health Planning and Development (OSHPD) for use in California hospital facilities and the Division of the State Architect (DSA) for use in California schools.

ConX is LA city (LADBS) approved and meets special detailing requirements for the most demanding seismic loading as well as the current U.S. Department of Defense anti-terrorism standards for blast and progressive collapse resistance.
