Study On Cost Control Evaluation Of Construction Project Dust

As the pace of urbanization continues to accelerate,my country’s construction industry is booming.At the same time,environmental issues have received more and more attention.According to information released by the Meteorological Bureau,the Middle East is the hardest hit area of smog.The high incidence of smog in autumn and winter is generally more than five days.Large-scale and long-term smog is a challenge to human life and health,and it also has a major impact on my country’s economy and society.Inhalable particles are one of the main components of smog,and building dust is the main contributor to inhalable particles.Therefore,controlling the generation of building dust is an important measure to control haze and protect the environment.This article takes this as an entry point.Firstly,through literature research,field investigation and related policy research,it seeks the factors that affect the cost control of construction enterprises’ dust,and initially draws up an index system for dust cost control.The Delphi method was used to screen and confirm the primary indicators by questionnaire survey,and finally formed a relatively complete indicator system.Secondly,when constructing the weight model of the evaluation model,the subjective weight obtained by the analytic hierarchy process and the objective weight obtained by the entropy weight method are coupled to construct a combined weight,thereby overcoming the disadvantages caused by a single weighting.With the help of fuzzy comprehensive scoring method,comprehensive evaluation of the cost level of dust control of construction projects is carried out.Finally,specific cases are used to verify the feasibility and applicability of the model,and provide a reference for future construction enterprise construction project dust cost control evaluation.
