Coordinated with Revit BIM and Structural Design for clash-free structural modeling across USA projects.
· WHAT ARE STRUCTURAL BIM SERVICES – IN SIMPLE TERMS: Structural BIM services use Building Information Modeling (BIM) to create intelligent, coordinated 3D digital models of a building's structural system - foundations, frames, columns, beams, and connections. These models replace traditional flat drawings with data-rich, clash-free structural documentation built in Revit BIM and aligned with BIM Modeling workflows that help architects, engineers, and contractors build faster, cheaper, and with far fewer on-site errors.

What is structural BIM and how does it differ from CAD?
Structural BIM (Building Information Modeling) creates an intelligent 3D model where every structural element - beam, column, slab, connection - carries embedded data about material, size, load capacity, and cost. Structural CAD drafting produces flat 2D drawings only. BIM is used on larger projects because it enables clash detection, quantity takeoff, 4D scheduling, and multi-discipline coordination - things 2D CAD simply cannot support.
Why do construction projects need structural BIM services?
Studies consistently show BIM reduces construction RFIs by up to 40% and cuts on-site rework by 30%. Structural BIM services help businesses improve coordination between architecture, structure, and MEP systems - detecting clashes in the model before they become expensive field problems. For commercial, healthcare, and high-rise projects, BIM is now a standard requirement on most US project delivery teams.
How does structural BIM modeling work?
We begin with your architectural drawings and structural design intent. Our Revit-certified engineers build a fully coordinated structural BIM model - from foundations to roof framing - with LOD specifications matched to your project phase. The model is coordinated against architectural and MEP models using Navisworks for clash detection, then used to generate construction drawings, shop drawings, quantity takeoffs, and 4D/5D outputs.

LOD (Level of Development) defines how much detail is modeled in your Revit structural model. We deliver structural BIM at every LOD - from early design coordination through fabrication-ready shop drawing output for construction and facility management.
LOD 100
Basic massing and overall structural form. Used for early feasibility studies and concept-level coordination. No detailed dimensions or material properties.
LOD 200
Approximate size, shape, and location of structural elements. Suitable for early design coordination and system-level clash checks with other disciplines.
Most requested
LOD 300
Specific sizes, shapes, locations, and quantities. Used for permit drawings, design coordination, and clash detection. The most common LOD for construction documentation.
Most requested
LOD 400
Complete fabrication, assembly, and installation information. Includes connection details, welds, bolts, and rebar. Required for BIM shop drawings and fabrication packages.
LOD 500
Field-verified as-built conditions. Structural elements match actual installed dimensions and locations. Used for facility management, maintenance, and renovation planning.
How we work
Our structured BIM workflow keeps every project on time, on LOD specification, and aligned with your BIM modeling Execution Plan - from kickoff through Revit model delivery.
We review your BIM Execution Plan (BEP), LOD requirements, software standards, project schedule, and structural design intent. Proposal delivered in 24 hours.
DAY 1-2
We collect architectural models, structural drawings, geotechnical reports, and project specifications. All inputs are reviewed for completeness before modeling begins.
DAYS 2-4
Our Revit team builds the structural BIM model to specified LOD - foundations, frames, connections, and all structural elements - with embedded data and correct family use.
DAYS 3-10
The structural model is federated with architectural and MEP models in Navisworks. Clashes are detected, reported, resolved, and documented before drawing production.
DAYS 7-12
Final coordinated BIM model, construction drawings, clash report, and all supporting deliverables are issued. We remain available for construction-phase RFI support.
DAYS 10-16
Every structural BIM project includes a complete deliverable package - the models, drawings, reports, and coordination files your team needs to build with confidence.
HOW WE COMPARE
Many project teams ask whether to use traditional structural CAD drafting or move to BIM structural modeling. Here is an objective comparison against 2D drafting workflows to help you make the right decision for your project type and scale.
| Capability | Traditional CAD Drafting | United BIM - Structural BIM |
|---|---|---|
| 3D Structural Model | Flat 2D drawings only | Full LOD 200-500 Revit model |
| Clash Detection | Not possible in 2D CAD | Navisworks multi-discipline coordination |
| Shop Drawings | Manual drafting - slow, error-prone | BIM shop drawings from LOD 400 model |
| Quantity Takeoff | Manual counting - inaccurate | Automated from BIM model - accurate |
| 4D / 5D Capabilities | Not available | 4D scheduling + 5D cost estimation |
| RFI Reduction | Dependent on drawing quality | Up to 40% fewer RFIs with BIM coordination |
Bottom line: CAD drafting still fits some workflows, but structural BIM adds 3D coordination, richer LOD, and takeoffs tied to the model - so teams that need fewer RFIs and clearer quantities tend to gain the most from BIM delivery.

Common Questions
Direct answers to the questions architects, engineers, and contractors ask most often about our Revit BIM and structural drafting services.
Structural BIM services involve using Building Information Modeling software - primarily Autodesk Revit and Tekla Structures - to create intelligent, data-rich 3D models of a building's structural system. These models go beyond 3D visualization: they carry information about every structural element, enable multi-discipline clash detection, support quantity takeoff and cost estimation, and can be linked to construction schedules for 4D planning. Structural BIM services are used on commercial, industrial, healthcare, and infrastructure projects to improve coordination, reduce errors, and accelerate construction.
Structural CAD drafting produces flat 2D drawings - floor plans, elevations, sections, and details - using AutoCAD. These drawings are construction documents but do not carry data and cannot be used for clash detection or quantity takeoff. Structural BIM creates a 3D intelligent model where each element has embedded data - material type, size, cost, manufacturer, and status. BIM supports clash detection with Navisworks, quantity takeoffs, 4D scheduling, and 5D cost estimation - capabilities that CAD drawings simply cannot provide. For projects under about 5 stories and with low coordination complexity, 2D CAD is often sufficient. For larger, more complex projects, BIM delivers significantly better outcomes.
LOD (Level of Development) describes how detailed and reliable a BIM element is. LOD 300 provides accurate sizes, shapes, and locations - suitable for design coordination, clash detection, and permit drawings. LOD 400 adds fabrication and assembly information - connection details, bolts, welds, and embedded plates - required for shop drawings and fabrication. LOD 500 represents as-built conditions - field-verified element locations for facility management and renovation planning. Most construction projects use LOD 300 for design and coordination, LOD 400 for fabrication and shop drawings, and LOD 500 for asset management after handover.
Structural BIM reduces RFIs through clash detection - a process where the structural model is federated with architectural and MEP models in Navisworks and automatically checked for conflicts. Clashes found in the model before construction are resolved at near-zero cost. The same clash found on site costs 10-100x more to fix - typically involving rework, schedule delays, and contractor disputes. Our BIM coordination services regularly identify hundreds of clashes per project before construction begins, giving the team the chance to resolve every one at the design stage.
Structural BIM modeling costs depend on the project size, LOD specification, number of disciplines being coordinated, and the deliverables required. A LOD 300 structural BIM model for a mid-size commercial building typically ranges from $5,000-$20,000. LOD 400 models with shop drawings and coordination are higher, depending on structural system complexity. We provide a fixed-fee written proposal for every project before work begins - with a confirmed scope, LOD, deliverables, and deadline. No open billing and no surprises.
Standard structural BIM modeling projects are delivered in 10-18 business days for mid-size commercial buildings. Smaller structures or LOD 200/300 models can be completed in 5-10 business days. LOD 400 models with shop drawings and full coordination typically take 14-22 business days. Rush delivery is available for time-critical projects. We confirm the exact delivery timeline in writing at proposal stage - and we meet it.
