  51. 51. Best Practices for Contractors Using Revit & NavisWorks
  52. 52. Construction Modeling in Revit-Best Practices  Develop solid workflow that allows updates to the design intent model  Download revised design intent model into builder’s construction model server  Use design review feature  Use Revit linked model Coordination Review Tool
  53. 53. Construction Modeling in Revit-Best Practices  Construction model is considered a different type of model from the design intent model  Use Revit Link” command to join construction model to design intent model  Construction model contains data vital to a builder  Be careful of accidental editing, moving or deleting of design intent model elements
  54. 54. Revit Design Intent to Construction Model Procedure  Check work sets  Apply shared coordinates  Create & import needed gridlines  Create & import needed match lines
  55. 55. Revit Design Intent to Revit Construction Model Procedure  Create & import building origin point  Divide the model into quadrants  When making modifications to model check the following:  Ceiling heights  Work sets  Partition Types
  56. 56. Revit Construction Modeling Options  Tracing of 2D CAD paper drawings  Convert design intent 2D CAD electronic file into a Revit 3D model  Convert 3D Revit design intent model into a construction model (use Revit linking feature)  Create a 3D construction model from scratch
  57. 57. Linking Revit Models  Linking prevents architect’s design intent elements from being altered  Linking allows contractor to add to architect’s design intent model without modifying it  Use Coordination Review tool for alerts to updates to lined models  Linking gives the contractor information vital to their work (e.g., gridlines, origins, clearances, alignments, etc.)
