Evaluation Of Building Construction Project Template Scheme

The real estate industry has driven the development of template industry,and the construction of real estate projects cannot do without templates.From the perspective of project cost,the cost of formwork accounts for about 30% of the cost of reinforced concrete structure,and the construction period of formwork accounts for about half of the total construction period.From here we can see that the importance of template in the construction of real estate projects is self-evident.Due to the emergence of a large number of super high-rise buildings,the construction period,safety,quality,cost and other aspects have higher requirements,which brings new challenges to the construction industry.How to improve the economic benefits of the enterprise by choosing a reasonable construction project template scheme is a topic worthy of our study.Therefore,it is very meaningful to study the evaluation of construction project template scheme in this paper.In this paper,value engineering method,comparative analysis method and case analysis method are used to study the template scheme selection of construction project.Firstly,the factors influencing the template selection are analyzed and the evaluation index system of template scheme is established.Secondly,according to the theory of value engineering,the fuzzy mathematics evaluation model and evaluation index system of construction project template scheme are established.Finally,a commercial and residential building in Xi’an city is selected as a case study.The value engineering method is used to analyze the function and cost of wood formwork,aluminum formwork and steel formwork,and it is concluded that aluminum formwork has the highest economic benefit.Through the comparison of different types of formwork,it is found that the safety function,technical function and construction feasibility have an impact on the economic benefits of construction projects.Therefore,taking these three factors as the basis of evaluating the construction template scheme,the evaluation index system of formwork scheme is established,and the index weight and scheme evaluation model are determined.Then,taking the template scheme selection of a commercial and residential building in Xi’an city as an example,experts are invited to grade and evaluate the aluminum formwork,steel formwork and wood formwork selection scheme.Then,the AHP and fuzzy mathematics method are applied to comprehensively evaluate the function index data of the formwork scheme.Combined with the value engineering method,the wood formwork value index is 184.00,and the steel formwork value index is 256.88 The value index of aluminum template is 310.66.According to the theory of value engineering,the larger the value index,the better.The results show that aluminum formwork is better than steel formwork,and steel formwork is better than wood formwork.The final scheme is to selectaluminum formwork,because the value index of aluminum formwork is better than steel formwork and wood formwork.When using aluminum formwork,it is suggested that the turnover of more than 32 times should be in the form of purchase,and that of turnover less than 32 times should be in the form of leasing,so as to save construction cost and improve construction economic benefits.Through the comparison of the economic benefits of aluminum formwork,wood formwork and steel formwork,it can be seen that the economic benefits of aluminum formwork are obvious.The aluminum formwork technology conforms to the promotion concept of green construction of construction projects in China,and is conducive to saving resources and protecting the environment,and promoting the harmonious development of the construction market.
