BIM-Enabled 3 Week Lookahead
During construction, there is a tremendous opportunity to wring waste out of the process. Consider the 3 week lookahead, pictured traditionally below:
The team at Q5 re-invented the concept, connecting the schedule and the Building Information Model:
This new brand of 3 week lookahead includes a visual representation of milestones, dimensional information as needed and the quantity of the work to be put in place that week (or day). The visual milestone allows all parties involved to understand not only where they need to be on a certain date, but why. The quantity extraction reduces waste and optimizes planning. Trades can plan crew size and precisely order materials. On the project shown, concrete was ordered according to the Building Information Model.
Schedule Simulation Enables Predictability
It isn’t that we don’t think there is a place for creating a Gannt-chart schedule; we just don’t think they are the best way to optimize and communicate schedule information.
Consider the following. Which is easier to understand, this:
Traditional Gannt Schedule for a Courtyard Mariott
or this?
We created this schedule simulation for a Mariott Courtyard after authoring a partial Building Information Model for it. Although this is one view of the final schedule linked BIM, the visualization was used to optimize the schedule during pre-construction. This enables a team to develop a schedule early on that can be delivered on. As this schedule is used during construction, it clearly communicates expectation and reduces the builder’s and subcontractor’s abilities to wiggle their way out of schedule committments. Not a bad thing, in our book.
