Nível de maturidade do processo de projeto: as quatro interfaces

Abstract

AIA’s level of development concept describes the completeness degree for a given element of the BIM model towards a previously defined reference. This proposition contemplates the levels of development of constructive elements organized from the Uniformat classification. Although this criterion properly specifies different sectors or systems of a building, it may lead to incomplete, compartmentalized views on the design, if understood separately. The original concept of level of development, called LOD in the literature, addresses two meanings – it is treated as level of detail, as well as level of development, which shows contradictions. The paper´s objective is to propose a new concept to resolve these contradictions and expand the meaning to the concept of Maturity Level, as a measure of the developing a design against to its previously set targets. This goal reference comprises business objectives – translated into programmatic requirements; BIM pre-defined uses – translated into specific sets of geometric and non-geometric properties; by geometric compatibility; and by the planning and control system
