Preliminary Project Descriptions (PPDs)
Preliminary Project Descriptions (PPDs)
express early design ideas that are understandable by owners, lenders, and
the general public.
PPDs describe building systems and assemblies by function and performance
rather than by construction products and materials. Instead of listing
bricks and mortar, for example, PPD's describe the exterior wall by
aesthetic function and weather resistance performance, allowing for design
options to meet the project's goals.
PPDs provide an opportunity to explore options for design and cost impact
before committing to a single solution. PPDs help narrow the many design
options to arrive at the best solution through the rigor of an industry
accepted format — the same format used for preliminary construction
estimating and Revit model assembly codes.
Coordinate the Revit model to link objects and schedules directly to the
PPD. Ask us to explain.
