Traditional measuring vs. Scan to CAD/BIM

As licensed architects, we have extensive experience compiling architectural as-built drawings.  We have shown here our experience in creating drawings in the traditional method vs. the method of laser scanning to CAD/BIM.  You can see the massive amounts of resources that are spent in the traditional way.

*Human inaccuracies always cost time and money, especially when those errors aren't realized until later in the design process.  

**Scan to CAD/BIM can be drawn exactly as it is in the field, but can be modeled orthogonal if walls are not plumb to make drawing easier.

***This example is taken from our experience of an average of numerous as-builts completed on existing buildings ranging from 1 story 10,000 sf buildings to 3 story 50,000 sf buildings.

****Cost depends on size, scope and detail of building(s).  Please contact us for more accurate estimates of pricing.
