Taking A High-rise Residential As An Example,the Analysis And Application Of The Influence Factors For The Cost Of Structure In The Design Phase

Design phase is the origin of the project,is a key to the success of the project,determine project contains the main content,but also influence the critical stage of the project cost in this paper,from the design process of main influencing factors of detailed analysis of the cost.In the design of the most important content is the influence of structure design,the same construction projects have different building use function,the structure arrangement,different security performance,and the corresponding will have different project cost,so in this paper,the structure of the building,respectively from the macro and micro factors nuanced analysis of cost control in construction,structure design of the main influence factors,and the content of the system introduces the concept structure design,based on the principles of the introduction of value engineering and quota design,optimization design is given at the time of the appraisal indexes and methods,make its form a complete set of process system,detailed operation of the actual project has a certain reference value.Then,by introducing some practical engineering cases,the same to draw different structure layout of construction projects,using PKPM software structure model is set up by the same parameters,comparing related concept structure indicators,and other functions,the cost of different scheme corresponding,through the application of value engineering design of the selected value,can effectively control structure via computation cost.Main content of this paper summed up: 1.The structure design of the macro factors mainly include: the selection of structure form,structure,reasonable layout,structure overall performance index of control;The micro factors mainly include: the determination of the upper component selection,material strength grades,reasonable structure,good control template.2.Better focuses on analysis and design phase must be considered,the relationship between architectural design and cost structure,its content mainly include:(1)design directly related to the project cost;(2)design influence daily expenses;(3)to design quality directly affect the investment details of architectural design cost control each link of the work process.3.The design phase of cost optimization of related theory and method,the content mainly include:(1)scheme comparison of value engineering in the design phase;(2)structure concept design safety evaluation index;(3)limit design in the design phase of the application of cost control.By the integral to the local details of the design process of a project through a series of scheme comparison and structure index analysis can get a cost control,guaranteeing function and the overall performance of high quality design.By introducing the value engineering,describe the application theory of the process steps,and the deficiency existing in improvement Suggestions are put forward.Introduction about the limitation of design index of the control theory and application,and puts forward some effective Suggestions for improvement.4.The introduction of the structure in concept design,detailed introduces the integrity of the meaning and function of the 7 comprehensive index,and the corresponding norms,make engineering design personnel can better grasp security functions at the same time,can further explore the effects of threshold indicators.5.Application and engineering example,detailed analysis of each index structure,the function of the comparison of different schemes,the cost coefficient,finally calculate the maximum value coefficient for the project structure optimization scheme,through the process of the application value of contrast method can effectively control the project cost,get the fully functional,the structural safety of optimal layout scheme.6.Combined with the article illustrates the problems of the design phase of cost control put forward some Suggestions for practical measures,roughly:(1)to strengthen the budget preparation,budget and design of personnel information communication;(2)strengthen the standardization of design,and on the basis of safety incentive cost control;(3)to strengthen cost in the design bidding stage than choose factors;(4)the introduction of the third party involved in strengthening the cost optimization,the supervision.
