  • This paper presents an algorithm for improving the constructability of construction facilities based on Artificial Intelligence (AI) concepts. This improvement is accomplished by visual simulation of the construction process during the design phase to avoid future constructability problems. By using a 3-D computer model of the facility, it will be possible to check for the constructability of different sequencing scenarios of various components of the facility prior to construction start. The goal of the algorithm is to find the optimum path for an object from one position and orientation in the 3-D computer model to another position and orientation. It optimizes the path subject to motion constraints on mechanisms which manipulate the object as well as ensures that there are no interferences along the path between the object and other objects in the path. The use of such an algorithm in construction planning is briefly introduced.
