In the early 1970s, LJB introduced an innovative system of tilt-up building design—CON/STEEL Tilt-Up Systems—for a select group of contractors. Our design-build relationships evolved into lasting partnerships, giving birth to the CON/STEEL Alliance. This select group of pre-qualified contractors relied on LJB's structural design services, and each Alliance member had exclusive rights to its geographic market. LJB and CON/STEEL were responsible for introducing tilt-up construction into new markets where the construction method was unknown.
While LJB no longer offers exclusive territories, we continue to provide the engineering, training and sales support that was at the heart of the CON/STEEL system. We continue to work with many of the contractors from the CON/STEEL Alliance – with some relationships dating back 40 years.
The photos below show some award-winning projects completed by LJB and its CON/STEEL Alliance member partners. Our design-build partnerships have earned more than 50 Tilt-Up Achievement Awards from the Tilt-Up Concrete Association.
See our YouTube channel for additional videos of high profile tilt-up projects designed by LJB Inc. and completed by general contractors in the former CON/STEEL Alliance.
