THE TECHNICAL SPEC: QUESTIONS GENERAL CONTRACTORS ASK
Straightforward answers regarding crew mobilization, crane logistics, airspace permits, and field welding tolerances.
Our core rigging crews and cranes mobilize within 5 to 10 calendar days of anchor bolt survey sign-off. We perform our independent 3D laser plumb audit 48 hours prior to steel arrival to ensure foundation tolerances are sub-millimeter before the first crane outrigger touches down.
Yes. We control dedicated all-terrain cranes (up to 130-ton), rough-terrain hydraulic truck cranes, and high-reach JLG boom lifts (80ft to 125ft). We do not broker equipment to third parties — your master schedule is completely independent of rental house shortages.
Gabriel and our in-house engineering staff calculate all 3D crane lift studies per ASME B30.5 standards, including crane radii, boom deflections, center-of-gravity rigging calculations, ground bearing pressure pads, and FAA Notice of Proposed Construction (Form 7460-1) where airspace permits apply.
We monitor continuous on-boom anemometer feeds. Crane picks are paused when sustained winds exceed 18 knots (20 mph) or gust thresholds specified in the pick plan. However, our deck crews shift immediately to bolt torque lock-in, plumbing guy-line adjustments, and ground shaking-out so zero jobsite hours are wasted.
Yes. Every crew lead and connector carries active AWS D1.1 (Structural Welding Code – Steel) and D1.3 (Sheet Steel Decking) certifications. If a fabricator hole requires field reaming, gusset plate stiffening, or moment connection welding, our certified riggers execute and log the repair immediately.
