Computer‐aided process planning (CAPP) is a key step in the integration of computer‐aided design and computer‐aided construction. The focus of our research is on the development of a CAPP system that will enable automated placement (i.e., pouring) of pumped concrete on a structural floor using computer numerically controlled (CNC) equipment. In this paper we describe the algorithms and methodologies comprising the CAPP system, including (1) algorithms for geometric reasoning (with the CAD model of a given floor) to recognize areas to be concreted and to extract features (such as elevator shafts) that are to be avoided during concrete placement and (2) combinatorial optimization procedures for identification of an efficient sequence of floor slabs to be concreted and the generation of a corresponding area‐covering, obstacle‐avoiding path plan for the pumped‐concrete placement pipe.
