Weather influence-aware robust construction project structure

Abstract

Construction projects consist of numerous technological operations. The operations can be usually arranged in a considerable number of alternative ways satisfying induced technological order. Applied arrangement of operations defines project structure. A project structure influences results of construction project schedule optimisation. Identification of adequate structure for a construction project is therefore important for obtaining the best possible schedule. Effects of construction project execution depend on influence of surrounding environment. It is therefore necessary to include local conditions in a building site to derive a reliable construction project schedule. A problem of bi-criteria time-cost optimisation of a construction project structure is dealt with in the paper. Presented optimisation approach includes sensitivity of technological operations to adverse local weather conditions. It is capable of estimating robust Pareto-efficient structures and corresponding schedules for a construction project. Appropriate allocation of alternative execution modes to technological operations satisfying limited availability of manpower, building materials and equipment is applied in this regard.
