Simple as 1, 2, 3

SketchUp is not a BIM modeling program. It does not format components or tabulate descriptions, there is no related data assignment, it doesn’t really work well across multi-platforms, it will not generate analytical reports and it will not automatically or even semi-automatically export a 2D drawing. And it is definitely not a drafting program -- though it will produce a great set of construction documents -- if you know what you’re doing.

It’s not about BIM At the same time, anyone can use SketchUp to build a detailed 3D model. Users include high end designers who render buildings in some pretty amazing ways, plus thousands who use SketchUp to visualize space, color, form, and shadow, lay out a stage, storyboard a movie, graphically illustrate a narrative, build a game, or teach almost any subject from K through 12 (and 13-25).

At the same time, no real constructor needs a model to visualize a set of 2D construction drawings -- it’s not that hard. Students even learn to imagine space and draft 2D floor plans, elevations, and sections in junior high school – though they prefer building 3D models.

Construction modeling is process modeling Important is that the real potential of construction modeling is in simulating a process. A construction model animates time. Here are some recent examples:
  • Site utilization planning (SUP), mobilization, and startup
  • Tricky lifts or placement of concrete, steel, and air handlers
  • Sequence safety lines while decking a high rise steel frame
  • Coordinate labor & material as floor phases, 36 story build
  • Simulate safety changeovers in placing fall protection
  • Designate safety zones and restricted areas changeovers
  • Simulate stair & deck installs on fast track steel frame
  • Determine distances, timing, staging, & material movement
  • Phase and process demonstrations and method sequencing
  • Scale safety zone markers for overhead material movement
  • Coordinate move-on, staging, & subcontract start-up
  • Scale a lay-down to maximize temporary dry storage
  • Crane arcs into storage areas and placement to grid lines
  • Most of you get it….it is not about BIM, drawings, or design

Simulate process as easy as 1, 2, 3
  • Step 1: Think out of the box, everything comes from a box.
  • Step 2: Inferences & guides to assemble a piece based model
  • Step 3: The Outliner and components control time captures
Once built, a static piece-based model can then be deconstructed to illustrate a process as a clickable series of steps or phases, a video that moves from place to place to record different views of an assembly process, or an animation that both anticipates and simulates movement on the jobsite.

Here are three simple examples to try:  

Clickable Scenes


Scene Properties used to set camera location, field of view, time/shadows, hidden objects, layers, and annotations. Click here to download the model.  

Video Capture


Animation settings used to set delay and transition between Scenes. Video then exported as a movie or captured with one of several free video capture programs. Click here to download the model.  

Motion Capture


Use the same scene by scene animation technique film makers use to capture CGI motion. Click here to download the model.
