1、 Highway engineering change reason analysis and cost of the project of influence Abstract: in the implementation stage because of highway engineering design factors, environmental factors, the influence of various engineering changes happened is more common, combining with engineering practice, this

2、 paper discusses the causes and engineering change of project cost. Keywords: engineering change, Reason, Cost Due to the highway project period, long, long line, so broad in construction of various causes by the engineering change is inevitable. Engineering change could lead to increase of construc

3、tion cost or time limit of the owner and the contractor, between the claim will claim and the cost of the project. Owner of change and the causes of the cost And when the owner change engineering bidding of construction conditions of commitment. SanTongYiPing referred to in the preceding paragraph,

4、the engineering tight finish, delay purpose will increase the contractors settlement fee, but little impact on total cost, the owner or project quantity change projects. Increase the project content or quantity, will increase the cost, Project content or cancel or reduce the number will reduce cost,

5、 but may affect the use function of engineering, because the owner with agreements for the existence of incomplete, or in the contract when division, can increase content of missing the contract cost, and the owners requirements, and shorten delivery of finished ahead of the original contract period

6、, invest more in construction unit cost of manpower and material resources, to increase, and improve the design standard requirement owner, beautiful Angle from security requirements of engineering structure change type, elevation, baseline, location, size and strength, make cost increase, and the o

7、wner to change in the construction organization design has approved the construction plan, cost increase, and the owner of the contract with the owner of the materials or equipment supply for the category and quantity, cause cost increase or decrease, and the owner of the contract specifies unreason

8、able, can make the cost is increased The design of change and the causes of the cost The design adopts the new standard, new technology, new technology, to replace the original design of the project, and put to use more favorable for owner reduce project cost, the depth of the design documents, cann

9、ot satisfy the relevant provisions of the relevant design phase of engineering change and requirements, cost increase or decrease, and when designing units in the preliminary design to fully consider the network planning, and in local government and related departments (e.g., environmental protectio

10、n, water conservancy, electricity, gas, communication, navigation, etc.) and the requirements of the project, the main structure change shape and size change etc, make the cost increase, and design personnel errors or omissions caused engineering change. Due to the two SanShen school system to imple

11、ment the change that cost is increased, Unit, uncoordinated cooperation between designers, or the highway facilities with the principal part of the project design, cause sync job change, make cost increase, and the design drawing not timely delivery time delay, provide, construction, make the cost c

12、ompensation shutdown caused by increased. Tthe contractor to change and cause the influence. Cost The contractor is unable to perform the contract or cant completely, the contractor shall take remedial measures proposed change, this kind of change of engineering cost, can increase by contractor burd

13、en loss, the contractor has been approved changes when bidding of construction project, this kind of change of cost, but almost no effect for the contractor may save construction cost, and the contractor for construction is convenient, or to shorten the construction period, or to reduce the investme

14、nt of construction, and puts forward such reasons, and more economical and reasonable, optimizing design scheme, this kind of change if owner recognized, can reduce the construction cost, also can reduce the cost of the owner and the contractor, mutually beneficial, According to the contract, the co

15、ntractor couldnt finish, engineering construction contract extension, the owner may terminate the contract terms, according to the content of construction contract in whole or in part, by the contractor, this kind of other changes generally does not make owner cost increase, but will make the contra

16、ctor under loss, due to the contractor technology or management of the error caused by engineering change, this kind of change to the contractor, the owner may claim generally do not increase the cost, stipulated in the contract, the contractor change by owner procurement materials, using other kind

17、s of materials, and therefore model brand damage by contractor, unless the owner to approbate, generally do not add cost the supervisor of change and the causes of the cost Supervision by the owner, commissioned by the cause of the change of the owner or expenses directly influence the cost. 1 and s

18、upervision engineer in order to coordinate the contractors operation, or section of this project contractors to coordinate with relevant departments or units where the relations of production, easy cause engineering change caused by increased cost. the site supervision engineers in actual situation

19、in the contract and the technical specification for the design, according to local modification and perfect or by design, this kind of change unit may cause increased cost. and supervision engineers work and coordination ability damage caused by lack of rework, engineering cost change work. and supe

20、rvision engineer proposed optimization design or construction, the design optimization or contractor agree, can reduce engineering changes caused by the project cost. The environment factors and impact on the cost of change Engineering geology unknown or insufficiency in design, engineering cost inc

21、reased to. and highway engineering construction projects from the construction, project feasibility study, design and construction drawing design to construction, due to various reasons, the project in the declaration and approval process, some problems existing in the construction stage, these prob

22、lems caused by exposure to change, and engineering cost increase. and national policies, laws and regulations and standard, the change of change, resulting in increased cost. Four, the local government of the peoples production and life convenient scheme adopted by engineering change after that cost

23、 increase. whose house is caused by delay, the work of engineering change, could lead to increased cost. Highway engineering change of a variety of reasons, this means that the appraisal work for engineering changes are complex and difficult to decrease the cost, the change of the effects are also d

24、ifferent. Through the analysis, is looking for engineering changes the various causes, and through the analysis of the cost control are not isolated, control cost, the key is to establish and perfect the scientific management system. Based on control cost, quality assurance and accelerate the progress, the principle of efficiency to determine the necessity and feasibility of engineering change. Only in this way can we truly achieve the effective control of the construction project cost and improve the economic benefit and social benefit.
