Study on trade-off of time-cost-quality in construction project based on BIM

Abstract

Abstract. With the development of BIM technology, BIM provides a new direction for the project management of three objectives. Based on the current situation of the project time cost-optimized mass balance studies, pointing out the implementation mechanism of achieving the trade-off of time-cost-quality in construction project based on BIM mainly oriented components of the BIM model based; the use of Structured Query Language query statistics data information needs combined bill of quantities calculation method for the specification, preliminary engineering scale generation; establishment of Project relations system model. In the process duration is subject, for the construction of uncertainty factors such as interest rates and prices, through the establishment of quality, cost and schedule function, the establishment of quality balanced schedule cost optimization model, using genetic algorithm model of the optimal solution are obtained. With BIM case finally proves the rationality of the model and the effectiveness of the proposed genetic.

Review of Optimization Dynamically Applied in the Construction and the Application Potential of ICT

“…Roofigari-Esfahan and Razavi built uncertainties upon the new concept of space-time float [85]. In [86], the uncertainty factors such as interest rates and prices are expressed by establishing quality, cost and schedule function. Abuwarda and Hegazy considered the uncertainty in geologic conditions as geologic parameters [58].…”
