SUB-MILLIMETER FOUNDATION AUDIT
Before the first truck rolls off the highway, Gabriel's team performs an independent 3D laser survey of all concrete footings and anchor bolt projections. If a foundation bolt is off by 3/16", we catch it and remediate it before the crane arrives on the clock.
- ■ Laser Transit Plumb: Dual-axis digital verification on all baseplate elevations.
- ■ Non-Shrink Grout Packing: Full bearing contact under heavy baseplate flange.
- ■ Sequenced Shake-Out: Iron marked with color-coded bay coordinates.
THE PRIMARY HEAVY PICKS & TIE-BACKS
This is where the choreography shines. Massive wide-flange columns and rafter uprights are set using coordinated dual-boom lifts and hydraulic derrick cranes. Connectors catch the steel in mid-air, spin spud wrenches into drift pins, and drop safety bolts in seconds flat.
- ■ Tandem Crane Lifts: Engineered spreader beams for 80ft+ raked portal columns.
- ■ Temporary Cable Guying: High-tensile steel wire ropes prevent wind displacement.
- ■ 100% Dual Tie-Off: Ironworkers clamped into retractable inertia reels at all times.
GIRDERS, TRUSSES & HIGH-TORQUE LOCK-IN
Open-web steel joists and heavy roof trusses form the vast column-free clear spans required for logistics sorting centers and aircraft hangars. Every A325 and A490 structural bolt is tightened using calibrated electric impact guns, marked with inspection dye.
- ■ Clear-Span Spans: Up to 180+ foot uninterrupted spans for high-bay logistics.
- ■ Turn-of-Nut Verification: Every bolt inspected for tension per AISC Specification.
- ■ Mezzanine Floor Beams: Heavy industrial floor capacity designed for automation bots.
METAL ROOF DECKING & WEATHER CLOSURE
With the primary skeleton secured, our high-speed metal deck crews lay corrugated roof panels and perimeter edge-angles. Sheets are fastened with powder-actuated pins or puddle welds to transform the frame into a rigid, wind-resistant structural diaphragm.
- ■ Diaphragm Shear Strength: Precision sidelap screw and puddle weld spacing.
- ■ Acreage Production: 25,000+ sq ft of roof deck installed and tacked per shift.
- ■ Leading Edge Protection: Continuous perimeter safety cables and warning lines.
RADIO & HAND CHOREOGRAPHY: ZERO AMBIGUITY
On an active steel job site, crane operators cannot hear over roaring diesel engines and wind shear. Gabriel enforces standardized crane signaling and synchronized deck choreography.
DEDICATED CRANE RADIOS
Direct two-way noise-canceling headsets locked to private frequencies. Only the designated signal person speaks to the crane operator.
DUAL TAGLINE RESTRAINTS
Every steel pick longer than 30 feet uses dual non-conductive synthetic taglines to prevent uncontrolled rotational swing in gusting winds.
LASER PLUMB SURVEY
Continuous laser plumb checks after every structural tier is tightened. We verify column verticality before releasing temporary wire guy-ropes.
RAPID ROOF HANDOFF
Clean deck surfaces free of loose screws, offcut metal, or discarded weld rods. Handed over to roofing contractors with zero punch list disputes.
