Revit Existing Conditions and As Builts Picking Up Pace : #BIM #Revit


My company’s primary focus is to document existing conditions and deliver to the client ‘something’ dimensionally correct.  This something has typically been 2D drawings, floorplans, elevations, sections, etc.  We have utilized Revit on jobs that have required such extensive documentation that it was simply more efficient to create a 3D model and export the 2D data then document and draw the traditional way.  In fact, we have documented existing conditions in 3D since 2003 because it was always simpler to be in and object oriented environment.  However, the deliverables remained in 2D.  However, almost everything we have done in the last 3 months has been Revit and delivering existing conditions building models in Revit.   And the uses of the model vary widely.

  • We surveyed and delivered a Revit model of two dormitories for a University in Revit, even though they did not have an installed seat, because they wanted to prepare for the future.
  • We completed a Revit model of a single floor of Class A Office Space to be used for new interior layouts and design
  • We are in the process of surveying and creating a model of a sprawling historic in built in parts starting with the main building in 1760 to a new hall built in 1984. This is to be used for master planning of the site which they will use for rendering and analysis and to integrate a new building that will house a new lobby and 50+ guest rooms.

So the uses of Revit are expanding, and even if they are not being used for 4D and 5D purposes its benefits for visual communication, analysis, and increased speed of design/drafting cannot be discounted.  However, when integrating among all disciplines the results can be outstanding across the board.

We were fortunate enough to be part of the successful team, through a fantastic effort put forth by HNTB, that will be involved with the GSA and surveying and modeling their properties nationwide. What we have seen is either through the ripple effect or from other companies just being proactive that Revit and BIM are making a lot of headway into the community.  Companies that we work with report that they hope to be doing all their projects in Revit by this time next year and with new ways of doing work, and changing workflow and even the environment comes opportunity.
