It depends on the size of the building of course, and scope, but the short answer is “not very long!”. Field work generally proceeds at the rate of 15-20,00 sq.ft. per day with typical office space, for floorplans-only, depending on the complexity of the layout. Lots of interior partitioning, angles and curves will slow down the process. Additional complicating factors are tenants (empty buildings go faster), security issues and availability, lighting, and clutter. If we’re doing full detail (power/comm, RCP, elevations), a surveyor will do from 5-10,000 sf/day, depending on complexity. Finishing CAD work goes much faster, as with our LTS system the bulk of the CAD work is done directly in the field! This is the beauty of our system! For example, a basic survey completed today can be processed and delivered, complete in final AutoCAD format, the next day! BOMA calculations will require an extra day or so, depending on building size.
