Building cost models are based upon major buildings systems as defined by the Uniformat II classification system.
Building and/or system models are experience-based and useful for conceptual cost estimating and/or capital renewal and/or life-cycle capital planning.
Building and/or system models are generally based upon the input of parameter values for each major Uniformat category as expressed in square feet, linear feet, ceiling height, number of floors, building type/use, quality, security, productivity, exterior finish, duty use, % heated/cooled, numb er of corners, and location.
Typical building types include office, laboratory, education, assembly, stadium, warehouse, police, fire, etc.
