BIM Modeling & VDC Coordination Services

Mechanical, Electrical & Plumbing (MEP) BIM

Ceiling plenums in modern commercial buildings are congested battlegrounds. Specifically, duct mains, fire sprinkler lines, cable trays, and sanitary pipes compete for identical clearance. To prevent installation gridlock, our team creates parametric MEP components in Revit. Consequently, every routing detail accounts for pipe slope, insulation thickness, and hanger brackets so your subs install without field modifications.

Structural Steel & Rebar Concrete BIM

Our engineers build structural models up to LOD 350 and LOD 400 that accurately reflect load-bearing configurations. In addition, our draftsmen detail rebar cage clearances, anchor bolt locations, and steel connection gussets. As a result, fabricators verify embed placements well before transit mixers arrive at the jobsite.

Architectural BIM & Building Envelopes

Architectural design models require clean geometric data to serve downstream trade execution. For instance, our modelers build parametric Revit families with verified thermal zones and exterior glazing assemblies. Because our models maintain strict dimensional control, your submittal packages navigate architect reviews with minimal redlines.

4D Construction Phasing & Simulation

In contrast to standard plans, static Gantt charts fail to communicate spatial logistics across crowded jobsites. By linking schedule parameters directly into 3D models, we produce visual construction simulations. Furthermore, project managers can preview crane radius clearances, laydown areas, and concrete pour sequences to prevent trade congestion before crews mobilize.

5D Cost Takeoffs & Preconstruction Estimating

Accurate bidding demands automated quantity extractions tied directly to physical building geometry. Therefore, our 5D BIM workflow links Revit schedules with our preconstruction estimating databases. As a consequence, takeoffs for concrete volume, steel tonnage, and duct surface areas automatically reflect every design revision in real time.

Laser Scan to BIM (Point Cloud Conversion)

Renovation and retrofit projects rarely match historical paper blueprints. For this reason, our team converts raw 3D LiDAR point clouds into millimeter-accurate Revit geometries. Ultimately, this reverse-engineering step prevents your field crew from hitting hidden structural bulkheads or unrecorded utility lines.

1. Hard Clashes

First, hard clashes represent direct physical intersections where two components occupy identical spatial coordinates. For example, an 18-inch supply duct may penetrate an engineered steel beam or a foundation pile cap. Consequently, we adjust elevations and offsets to eliminate these overlaps before fabrication.

2. Soft / Clearance Clashes

Second, soft clashes involve violations of required operational or safety buffers. Specifically, high-voltage conduit runs must respect minimum clearance distances from steam lines according to building codes. Therefore, we configure dedicated service corridors around all valve manifolds and equipment access panels.

3. Workflow / 4D Clashes

Finally, workflow clashes arise from construction sequencing conflicts where one subcontractor’s work physically blocks another trade. As a result, resolving these staging issues early prevents costly jobsite downtime and union jurisdictional disputes.

Core BIM Modeling

Autodesk Revit (RVT), AutoCAD Architecture, Navisworks Manage (NWD / NWC), and Autodesk Construction Cloud / BIM 360.

Fabrication & Detailing

In addition, we deploy SysQue, Fabrication CADmep, Tekla Structures, and SDS/2 for steel connection integration.

Open BIM & Interoperability

Furthermore, we support Industry Foundation Classes (IFC 2×3, IFC4), BCF (BIM Collaboration Format), and 3D DWG.

Submittal Deliverables

As a result, you receive high-resolution vector PDF packages, native Revit files (.RFA), Navisworks clash reports, and Excel summaries.

Model Ingestion & Audit

First, we assemble your architectural prints, structural engineering files, and equipment cut sheets into a unified Revit project workspace with confirmed coordinates.

Trade Modeling & Routing

Next, our team models all MEP trades, structural assemblies, and architectural elements up to the agreed LOD, ensuring proper insulation clearances.

Navisworks Clash Audit

Subsequently, we execute hard and soft clash audits to flag trade overlaps and provide practical re-routing solutions for trade approval.

Sign-Off & Extraction

Finally, we publish coordinated federated models, verified shop submittal sheets, and fabrication spool drawings ready for site deployment.

What is the difference between standard CAD drafting and BIM services?

CAD produces flat, two-dimensional geometric lines that show basic dimensions without embedded intelligence. On the other hand, BIM develops parametric 3D models containing real-world material properties, model numbers, flow rates, and cost data. Consequently, when an element updates in BIM, every associated elevation, section, and schedule automatically updates across the entire project.

Can you lead weekly multi-trade BIM coordination meetings with our subcontractors?

Our VDC managers frequently act as the lead BIM coordinators for commercial general contractors. Specifically, we chair weekly online clash meetings, present filtered Navisworks viewpoints, and assign actionable resolution tasks to trade subs. As a result, project teams eliminate delays and track RFI closeouts until the federated model is fully signed off.

What files do you need from us to begin modeling?

We accept all standard architectural, structural, and MEP engineering drawings in PDF or DWG format. In addition, we incorporate equipment cut sheets, structural specifications, and existing architectural Revit files as our project coordination baseline.

How do you prevent hundreds of false-positive clashes in Navisworks?

Automated software audits frequently report thousands of irrelevant clash notifications. To eliminate this noise, we build customized search sets and tolerance rules inside Navisworks Manage. Therefore, your trade teams focus strictly on critical structural penetrations and trade crossovers.

Can you extract preconstruction quantity takeoffs directly from the Revit model?

In fact, one of the primary benefits of our 5D BIM workflow is automated quantity extraction. Because every wall, duct run, and footing is modeled to exact dimensions, our estimators generate verified takeoff sheets for material procurement and bid tracking.

What is your typical turnaround time for an initial clash report?

For mid-sized commercial projects, we usually deliver initial federated models and the preliminary clash detection matrix within 4 to 6 business days. Furthermore, expedited milestone delivery is available for urgent bid deadlines.
