从现行的基本建设程序上讲，可行性研究后，提出项目建议，审批后，建设方委

From the current basic construction procedures, after the feasibility study, the project proposal is put forward, and after approval, the construction party entrusts a qualified design unit to carry out the preliminary design. The design unit preliminarily determines the overall project according to the function and requirements of the project Diagram planning, single unit, and related supporting planning to achieve the function of the project. In this preliminary design, most of the preliminary design is completed by planners, architects and related professional engineers, and cost engineers rarely intervene. The people who do not have the professional knowledge of cost, the factors that affect the project cost are naturally not comprehensive, and they are often prone to unnecessary waste, such as differences in geological conditions, differences in structure selection, differences in the balance of earth and stone in the site, etc. The unnecessary increase and waste of the project cost caused by the project cost consulting agency in the preliminary design stage can avoid the waste caused by the above reasons, so that the project cost control of macro-control and micro-guarantee can be truly reflected. idea

From the current basic construction procedures, feasibility study, put forward project proposals, after approval, the construction party commissioned the corresponding qualified design units for preliminary design, design units according to the function of the project and its requirements, to initially determine the project's overall plan, monos, as well as related supporting planning, in order to achieve the function of the project, in such a preliminary design, most of the planners, architects and related professional engineers to complete, and the cost engineers rarely involved, because the implementation of the people do not have cost expertise, The factors affecting the cost of the project are naturally incomplete, often easy to cause some unnecessary waste, such as due to differences in geological conditions, due to differences in structural selection, the difference in the balance of soil and stone in the field caused by unnecessary increases and waste of the project cost, if the initial design phase is followed up by the engineering cost consulting body, can avoid the above reasons caused by waste, so as to truly reflect the macro-control, micro-guaranteed engineering cost control concept

In terms of the current capital construction procedure, after the feasibility study, the project proposal is put forward, and after the approval, the construction party entrusts the design unit with corresponding qualification to carry out the preliminary design. According to the functions and requirements of the project, the design unit preliminarily determines the general layout planning, monomer planning and relevant supporting planning of the project, so as to achieve the functions of the project. In such preliminary design, most of the design units are qualified It is completed by planners, architects and related professional engineers, but cost engineers rarely intervene. Because the implementers do not have the cost professional knowledge, the consideration of factors affecting the project cost is not comprehensive, and it is easy to cause some unnecessary waste, such as differences in geological conditions, differences in structure selection, differences in earthwork balance, etc If the preliminary design stage is followed up by the project cost consulting agency, the waste caused by the above reasons can be avoided, so as to truly reflect the concept of macro control and micro guarantee of project cost control
