shortcomings of revit for contractors

We (the "BIM Team" at Tocci Building Companies) were just given a presentation by Hunter Marston, of Autodesk Consulting. Hunter showed us a Revit add-on tool that facilitates scheduling. As amazing as the presentation was, it really surprised us that this tool isn't part of Revit. In fact, Revit doesn't even have plans to include it in Revit 10.0.

Revit 9.0 has limited tools for contractors; the construction tab of the design bar gives 3 options:
  • Site Components, where you can insert trailers, cranes and other logistics components
  • Phases, where you can add phases to the model and customize phase filters
  • Schedule/Quantity, where you can create quantity takeoffs
Compare those 3 options to the structural tab (which has 12 options) or the rendering tab (15 options) - keep in mind that Revit has other programs which can do advance structural modeling (Revit Structure) and high quality rendering (3D Studio Max). Also keep in mind that the construction tools that exist are limited; phasing is cumbersome and time consuming, site components are not entirely parametric (try putting a temporary fence around a site) and quantity takeoffs sometimes do not include important parameters (try calculating steel tonnage).

How does Revit expect to compete with Constructor, a BIM tool that currently does everything? There are obvious advantages to using Revit - you don't have to give up your current software systems, like Timberline and Primavera. Also, it is an Autodesk product & Autodesk AutoCAD is the most widely used 2D CAD software in the US. By using Autodesk Revit, we are easing collaboration with all AutoCAD architects and users. However, as we continue to implement BIM using Revit, we are getting frustrated by the limitations of the software.

I implore everyone who is either using Revit (despite its current limitations) or interested in implementing BIM (utilizing Revit), to contact their Autodesk reseller (or me) with their comments regarding the limitations of Revit as well as their own "Revit wish list". I plan on compiling my own "Revit wish list" (as I've seen on other BIM/Revit Blogs) and will be contacting the Revit product manager with our comments.

Revit Wish List
  • A more intuitive phasing tool, that allows the user to set start and end dates, instead of merely naming a phase
  • A phasing tool bar, with a drop down box for changing the phase filter of the current view
  • More detailed phasing, so that the layers of walls can be phased separately and window openings phased the same as the walls they are in (with the window scheduled at a later phase)
  • All object parameters should be available for schedules
  • More parametric logistics objects (i.e. temp fencing) and a wider variety of logistics objects
  • More API tool inclusions, so that team members who are less familiar with Revit can contribute to the model (i.e. the schedule tool that can be exported to Primavera or MSProject and then imported back into the Revit model

Don't get me wrong; I love Revit and couldn't imagine a better BIM software to use. I only criticize out of love.
