Stadium Long-Span Structures Deflect
Up to 6 Inches Under Load
The Challenge
Deflection readings recorded but not compared to limits
Survey crews measure truss deflections, column plumbness, and bearing pad alignment. Paper field books capture numbers but nobody compares them to the structural engineers allowable limits until the weekly meeting.
Bolt torque records disconnected from locations
A 50,000-seat stadium has over 47,000 structural bolts. Paper torque logs record values but matching a torque reading to a specific connection on a 300-foot truss requires cross-referencing drawings nobody has in the field.
Post-tensioning sequences not verified in real time
Concrete bowl structures use post-tensioned cables that must be stressed in a specific sequence. Paper logs capture jack pressures and elongations but cannot verify the sequence was followed correctly until after the fact.
Retractable roof mechanism alignment tracked manually
Retractable roof systems have rail alignments, motor synchronization, and weather seal tolerances measured during commissioning. Paper punch lists cannot track the hundreds of adjustment points across a 600-foot span.
The POD Advantage
Voice-logged survey readings with limit checks
Speak deflection readings, plumbness measurements, and bearing alignments as you survey. POD compares every reading against structural engineering tolerances and flags exceedances immediately.
Bolt torque mapped to connections
Every torque value GPS-tagged and linked to the specific structural connection on the 3D model. Full traceability from bolt to beam to truss to roof system.
Post-tensioning sequence verification
Stressing sequence tracked in real time against the engineers required order. POD prevents out-of-sequence stressing by alerting when the next cable does not match the plan.
Retractable system commissioning tracker
Every rail alignment point, motor test, and seal measurement tracked through commissioning. POD shows system readiness as a percentage with every deficiency itemized.
Structural Monitoring Intelligence
“We had a 340-foot roof truss deflecting beyond tolerance during a concrete pour on the concourse below. The survey crew measured it but the reading sat in a field book for two days. POD would have flagged that deflection in real time.”
