Study On Construction Ability Of Engineering Design For Large-scale Construction Project

At present the traditional engineering construction model in construction market is design and construction tasks were borne by different types of units and people,divided into two completely independent and professional work,reduces communication between design and construction work,the construction unit and design unit is the main participants,the early stage of the project design phase construction units after the construction unit to complete the design and construction bidding and to participate in the project,to separate the design and construction at the organization level,designers in the design requirements related to the construction unit is a lack of understanding,and part of the design personnel's incompetence has on the implementation of construction projects,construction or is difficult to produce the inconvenience of problems,which have great influence on construction project management.In this paper the construction problem of large construction projects on qualitative analysis and sum up,through the construction of large construction projects is an in-depth and comprehensive analysis,pointed out that the root causes of constructability problems mainly the design and construction of phase separation led to the design and construction of communication;Is also referred to as the design of construction problems,may lead to design changes and delay the construction period,increase the cost,moreover can cause has finalized the design plan of part of the work to redo the part adjustment or have completed the construction,to the whole project participants to bring bigger loss.The study of construction related literature and data to comb and finishing,to analyze the causes of project feasibility problem,through the establishment of evaluation model,the analysis of large-scale construction project design value of constructability study significance.And constructability study should break the traditional design bidding-build mode and the limitation of traditional way of project management,new design and construction general contracting mode should be adopted and the establishment of constructability constructability study evaluation model;This article first to the large-scale construction project design in construction construction connotation and review,analyze the cause of the problem,review the main content of construction and application.Request to the project engineering design process,respectively for preliminary design,construction drawing design phase construction,this paper analyzes the factors which influence.Second,build influence construction large construction projects construction level 3 index evaluation system,combined with analytic hierarchy process(ahp)and comprehensive fuzzy analysis method to establish weighted fuzzy yuan,construction evaluation model is setup,and use comprehensive evaluation,the evaluation index of the model construction by European progress calculation results,it is concluded that the factors affecting the comprehensive optimal design scheme.Finally,combining with engineering examples,using the large construction project construction evaluation model is established,through the verification of actual case large construction project design construction evaluation model is feasible.Through the combination of qualitative and quantitative methods,in the construction of engineering design,on the basis of qualitative analysis,the factors which influence further classification,practical,environmental impact,including establishment of functional elements such as applicable construction requirements and construction evaluation index system,using the analytic hierarchy process,such as the establishment of a new construction evaluation model of optimal scheme,through the use of BIM building construction model visualization technology to help solve the large construction projects of construction of the actual problems;...
