Revit Pot Odds

In honor of today being my 21st birthday I would like to make a fun comparison: Revit and Poker. One of the things that I love to do (besides this blog) is play poker. With friends, online, and finally at the casino.

The best comparison between Poker and Revit that I think about when playing is calculating pot odds. This is not a poker blog so here are some resources for those of you who don't know much about poker math.

Now... to make the stretch and comparison of f AutoCAD vs. Revit using Pot Odds:

Project: Single family residential dwelling.
Budget (Pot) : $800,000.00
Timeframe : 100% CD's must be completed in two months.

The owner has a choice of an AutoCAD using architect or a Revit using Architect. Let us pretend that the Architects fee's are roughly the same. Making easy math we will say:

Architectural Fees : $10,000.00

Before the client will make a call of $10,000.00 into a pot of $800,00.00 he/she must now calculate the amount of outs.

Preflop the client has: Two Architects, one using Revit and one using CAD. The client liked the design proposals from both architects but felt the Revit architect's proposal told the "story" of the house better thanks to some 3D renderings and perspectives.

With the CAD Architect he hits a couple plans and elevations on the flop. With the Revit Architect he hits plans, elevations (with light shadow detail), isometrics, and perspectives on the flop. Now, the client must calculate how many outs he has left in the deck:

CAD Architect:
  • Detailed CD Plans (all seperate 2D drawing files that have a possibility of not accurately lining up from floor to floor).
  • Finished Exterior Elevations (Let's hope the final design does not have an angled masses)
  • Sections (Also have a possibility of not coordinating with plans.) Must be drawn from scratch, line by line, for every view.
  • Coordination of sheets, views, sections, and details. This process could also require a tone of "check sets" and possibly more money in the pot for the future.
  • All door, window, finish, and fixture schedules will be manually done and have the possibility of not coordinating with the project.
Revit Architect:
  • CD Plans are half way done. All levels will align perfectly.
  • Exterior elevations are already drawn and more can be generated at the click of a button. Even that 45 degree garage.
  • Sections are half way done as well. Little detail and notation work remains and more sections can be cut at the click of a button.
  • Coordination or views, sections, and details is automatically completed. No more check sets.
  • All schedules are automatically generated and will never be incorrect.
  • Cost analysis could be performed at the click of a button.
  • Energy analysis could be performed at the click of a button.
  • Structural analysis could be performed at the click of a button.
  • Daylight analysis could be performed at the click of a button.
  • Shadow studies could be performed at the click of a button.
  • Specifications could be performed at the click of a button.
  • Renderings could be performed at the click of a button.
  • 3-Dimensional views could be created at the click of a button.
  • An intelligent virtual model of the building will be given to the owner for future operations, maintenance, and construction.
With the CAD Architect the client has 5 outs and with the Revit Architect the client has 14 outs. Lets say the whole deck is 16 cards (with a walkthrough and physical model not included in the outs).
  • CAD Architect : 31.25% chance of client making his/her hand.
  • Revit Architect : 87.50% chance of client making his/her hand.
Therefore, an 80% chance of client making his/her hand will be needed to justify the call (800,00/10,000 = 80%). With the Revit Architect at an 87.5% chance... which do you think is the better hand?
