Indianapolis International Airport

While jacking a structurally complex, wing-like roof structure to design elevations at the new Midfield Terminal Building, a 110-foot long 12-foot deep roof truss shifted downward, resulting in a shutdown of the roof construction for several months.

RRJ was retained by legal counsel for the structural steel erector’s engineer to investigate the cause of the shift in the roof shoring/jacking system. Additionally, RRJ provided technical assistance in developing a procedure to lift and restore the roof structure to planned final design elevations in a very short time without damaging the roof structure or overloading the shoring/jacking system.

How RRJ helped

• Conduct structural investigation
• Survey pre- and post-shift conditions
• Develop computational models of roof structure and supports
