Study On The Influence Of Construction Scheme On Project Construction Cost Under The Price Pattern Of Quantities

Building products is a special product.It involves large investment,long construction period and involves a wide range of professional.If the cost failed to be controlled,it will cause three-excess phenomenon.So it is essential to the entire process construction cost.To do a good job in construction cost control is conducive to the successful completion of the project.It also can achieve design goals and produce economic benefits.The main purpose of this paper is to control the cost by the construction plan.At the same time,the construction meets the quality and duration requirements.Since 2003,the bill of quantities valuation model is implemented by the Government.This is the future mainstream model which can reflect the fair market competition and enterprise level.This paper first introduces the domestic and international engineering pricing model.We can learn experience and inspire how to progress.Introduce the differences and connections between the current list and quota.So it is easy to understand the necessity of quantities list valuation.And we need to realize the progress and limitations of the new code of valuation with bill quantity.We should be familiar with the composition of the cost of the project.The control of the project cost have different emphases at different stages.We need grasp the focal point and take measures to control the cost.There are many factors affecting the cost and analysis of the construction program is one of the important factors.Construction plan is the basic basis of engineering cost activities and reflects different costs.The design and construction plan should be based on scientific and reasonable principles.And on this basis,there is still a lot of plans for choice.Taking engineering examples,the change of construction cost is caused by changing the construction plan.The cost of the project is determined by quantities list valuation.The factor sets and weights are determined by the method of comprehensive scoring and the optimal scheme is evaluated.Because of different construction plans,the extent and extent of the impact is also different.Three examples are chosen,foundation pit support,formwork engineering and earthwork excavation construction machinery.Each case has two construction scheme.The different schemes are discussed and studied.It is found that the constructionprocess has the greatest impact on the cost.The materials and machinery are second.In view of the influence of the construction scheme on the cost,a scientific evaluation and quantitative index need to be used to judge the construction plan.And it can help to determine the optimal construction plan,control the cost of the project and achieve the construction goal.Construction enterprises should be encouraged to optimize construction plans to highlight the benefits of market competition.At the same time,it is also beneficial to further improve and improve quantities list valuation.
