Spatial layout design problems are related to grouping objects with similar properties, assigning objects to pre-defined groups, positioning objects in a constrained space, as well as finding a path connecting certain objects in a tri-dimensional world. Representation, reasoning and documentation for spatial layout design problems are expensive, inconsistent, incomplete and imprecise. This paper proposes a framework called SpADD (Spatial Active Design Documentation) to assist designers in spatial layout design tasks, from a set of objects and a set of spatial constraints relating these objects. SpADD is based on an ADD (Active Design Documentation) approach extension, a canonical parametric network model, an engineering decision-making model and an object oriented class model applied to spatial layout design tasks. Initial results of using an implemented version of SpADD for preliminary design of oil pipeline layout in deep water oil fields are discussed.
