【正文】 ment construction technology and construction project management of the organic integration of product it is after the project construction activities in an orderly efficient scientific and reasonable to carry out the guarantee. Its characteristics are: 1 includes both techniques including economic more precisely the bination of technical and economic documents can solve the technical problem but also consider economic effect. 2 of the whole file quote overall quote refers to the engineering object is whole file content is prehensive play is full. 3 is a guide to contracting process from start to pletion of bidding end. The construction before after all in all sorts of problems to be considered and make are as on able analysis piled on the construction activities for full deployment guide the construction preparation and construction process technical economy document. It from the construction of the overall situation according to the specific conditions formulate construction scheme determine the construction program construction flow construction sequence construction method and technical measures of organization labor organization arrangement of construction schedule and labor equipment materials ponents and various semifinished goods supply on the road transport site use water and electricity energy guarantee onsite facilities layout and construction planning in order to predict construction in a variety of needs and its changes to prepare in advance the design and construction technology and economy front and rear the overall business activities and construction project the construction units departments and between each project stage the relationship between the organic coordination so that the whole construction process of a scientific and rational management system so as to achieve the best people turn material resources to good account high quality low cost high efficiency to obtain the best economic benefits. Construction organization design as a whole prehensive technical and economic documents is a munication bridge between engineering design and construction. It should not only show the proposed project design and use requirements but also accord with the objective law of engineering construction whole process of construction plays an important role in the planning and guidance .Mainly has the following several points. (1) It guide the engineering bidding and engineering contract signed as a bid to the books content and part of contract. (2)It’s for guiding the construction before the disposable prep and the entire process of construction work. (3) as a project management plan documents proposed construction schedule control quality control cost control safety control field management each factor of production management and technical measures of organization enhance prehensive benefits. Construction organization design of classification according to the construction organization design stage can be divided into two categories: one category is prior to bidding construction organization plan referred to as the standard design another kind is the engineering contract signed after preparation of the construction organization design referred to as the standard design. A building or a group of building construction must be by a lot of work to finish .Every project construction process can take different construction methods and different construction tools. The building or building group of construction sequence often have different arrangement. Every member can be produced by different mode of production every kind of transport operation can adopt different means of transport and transport operation. Work on the mechanical equipment warehouse yard and office space often can have different arrangement scheme. In short whether in technology or in the organizational aspects usually have many feasible schemes for the construction of personnel selection but a different schematic economic effect is not the same. To this end (1) contracting parties in the editorship of engineering investment not only familiar with the construction drawings choose the applicable quota cost standard but also indepth field set collate carefully as appropriate construction organization or construction plan. The different construction organization or construction plan will directly influence the quota subitem of the sleeve and influence from the engineering cost. As the employer in the pipeline project cost should be strictly from fine from solid improve the accuracy of project cost eliminate overestimate risk eliminate unfair to improve project cost phenomenon as a construction method for a project contract authority must optimize construction organization design so that the series of the project cost more accurate.( 2 )the construction drawing budget quantity statistical table that lists the unit works in all kinds of labor and materials required quantity it is construction unit the preparation of construction plan reduce the project cost and reliable evidence accurate or not will directly affect the construction preparation work. (3) the accurate construction graph budget can make construction method to execute economic accounting and strive to ensure quality and construction period of the premise with less l
