In the construction process, a large number of resources are consumed in a short period, leading to high intensity and concentration of carbon emissions. From the perspective of China’s Double Carbon Policy, a multiobjective optimization problem integrating BIM technology and intelligent optimization algorithm is proposed in this paper. Firstly, using BIM modeling software to construct a 3D model generates bills of quantities as the basis to obtain the initial research data. Then a mathematical model of time-cost-carbon emissions is constructed with the idea of multi-objective optimization and a double-layer encoding NSGA-II algorithm is designed to solve the optimal set of solutions for the combination of activity execution modes under the premise of satisfying the priority relationship. Finally, a construction project is used as a case to verify the feasibility and rationality of the problem proposed in this paper, and demonstrate that the method can effectively guide the optimization management of the construction process, reduce construction carbon emissions, and promote sustainability of the construction industry.
Key words: Multiobjective optimization / BIM / Project management / Carbon emission / NSGA-II
