Traditional 2D workflows can't keep up.

Building Information Modeling (BIM) has become the answer. Software like SketchUp made 3D modeling accessible, even though SketchUp itself isn't true BIM—it captures geometry but lacks the intelligent object data that defines BIM.

Contractors and subcontractors have been slower to adopt, often continuing with 2D AutoCAD workflows familiar to senior staff.

Many experienced contractors prefer 2D for good reasons:

  • Cost: BIM software licenses are expensive, especially for small subcontractors
  • Talent: Hiring BIM-skilled staff is difficult and costly in competitive markets
  • Workflow familiarity: Decades of experience with AutoCAD make change resistance natural
  • Detail representation: Certain construction details—annotations, call-outs, dimension blowups—are legitimately easier to produce and read in 2D

Can we blame them?

BIM enables teams to overlay all discipline models in 3D and run automated clash detection.

However, the ROI far outweighs the investment.

Calculate your personalized Connected CMMS ROI

You can calculate the return on investment with Connected CMMS platforms by answering a few simple questions.

It ensures architects, contractors, engineers, and facility managers always work from synchronized data.

  • Reduces communication gaps between project phases.
  • Enhances accountability through change tracking and version control.
  • Simplifies coordination between teams working across multiple locations or time zones.

Tip: Integrate your BIM model with a Common Data Environment (CDE) to ensure seamless information flow and eliminate the risk of version mismatches.

Level 5 BIM adds cost estimations, budget analysis, and budget tracking to the information model. This data allows governments, municipalities, and property managers to make informed decisions based on information derived from the model— even after the building is constructed.

From blueprints to CAD to BIM

In the past, blueprints and drawings were used to express information about a particular building plan.

Facility teams can analyze asset performance, predict failures before they occur, and schedule service at the best possible time, keeping downtime and disruptions to a minimum.

3. 3D modeling: BIM starts with a digital 3D model that represents every building element — walls, HVAC, lighting, and more.

Design clashes between systems (like electrical and plumbing) are detected early, reducing rework and construction delays.

4. However, with global BIM mandates accelerating, this is changing—contractors who delay adoption risk being locked out of major projects.

This is where BIM service providers add value.

This model acts as a shared source of truth for architects, engineers, contractors, and facility teams, helping everyone work from the same data.

Here’s how it works across the building lifecycle:

1. Watch episode one!

Global infrastructure spending is surging—from AI data centers and hospitals to power grids and water treatment plants.

Facilio was recognized in the 2025 Verdantix Green Quadrant for Commercial CMMS, placing it among the most capable and forward-thinking platforms globally. Whether you need full-service BIM coordination, model conversion from 2D, or trained BIM personnel for specific projects, outsourcing provides BIM capabilities without the overhead of permanent staff and software investments.

As BIM technology continues to evolve—with AI, cloud platforms, and web-based tools—the industry's digital transformation will only accelerate.

Each component carries data about its size, material, and performance, creating an intelligent model that supports design, analysis, and maintenance decisions.

2. Too much detail upfront wastes time on elements that may change.

What Is BIM?

BIM is an acronym for Building Information Modeling or Building Information Management.

Turn maintenance from reactive to predictive
When BIM connects with your CMMS or digital twin, maintenance planning becomes proactive. Simplify renovations and retrofits

With accurate as-built data in hand, upgrades or repairs become far easier to plan. As design solidifies, elements gain specific properties—wall assemblies, structural sizes, equipment specs (LOD 300)—enough for coordination but not fabrication.

For Contractors (LOD 350-400): Construction-level models include connecting and interfacing information.
