offerings

Image: model-based quantity takeoff

5D Model-Based Estimating and QTO

Bridge the gap between 2D drawings and accurate bid estimates. We build intelligent structural models to dynamically extract net quantities, giving preconstruction teams full material traceability:

Automated structural steel tonnage takeoffs by shape, size, and grade.

Net cast-in-place concrete volumes broken down by pour sequence, element, and strength specification.

Reinforcing steel (rebar) weight takeoffs by bar size, lap requirements, and placement area.

Independent model-to-bid discrepancy verification against 2D contract sets.

Multi-Trade Coordination and Spatial Clash Detection (LOD 300 to 350)

Eliminate interferences between structural framing, gravity systems, and complex MEP distributions before steel is cut or concrete is poured:

Model federation and clash detection in CDEs.

Weekly coordination meeting management, BCF issue publishing, and live RFI tracking.

Verification of beam web penetrations, embeds, base plates, and anchor bolt clearances.

Formal sign-off packages for General Contractor and Engineer of Record (EOR) approval.

Direct-to-Fabrication Structural Detailing (LOD 400)

Transition seamlessly from design approval to the fabrication floor with production-ready detailing packages:

Structural Steel: AISC-compliant shop assembly drawings, erection plans, anchor bolt layout sheets, hardware lists, and CNC files.

Cast-In-Place Concrete and Rebar: Bar placement plans, rebar tags, lap-splice details, chair/standee schedules, coupler locations, and Bar Bending Schedules (BBS).

Light-Gauge Framing and Timber: Shop layouts, truss profiles, and connection assemblies.

Impact and ROI

Measurable

project impact

$1,500 to $5,000+

Elimination of field rework

The average structural clash discovered in the field costs between $1,500 and $5,000+ per incident in crane downtime, field cutting, welding, and rush engineering approvals. Pre-resolving interferences at LOD 350 guarantees seamless field assembly.

35% to 50%

Accelerated detailing cycles

Extracting fabrication drawings, piece marks, and CNC cut files directly from an approved LOD 400 model shortens detailing turnaround times by 35% to 50%, ensuring structural steel and rebar arrive on site on schedule.
