What are the characteristics of the design and construction phases of construction projects?

Characteristics of the design and construction phases of the construction project

1. Characteristics of the design phase

(1) The design work is expressed as a creative mental labor. There is no necessary connection between the amount of design labor input and the quality of the designed product.

(2) The design stage is the main stage in determining the value and use value of construction works. In the design stage can basically determine the value of the entire construction project, the accuracy of which depends on the depth of the design achieved and the degree of perfection of the design documents.

(3) the design stage is the key stage affecting the degree of investment in construction projects. Here the "degree of investment" can not be understood only from the absolute amount of investment, can not be concluded that the less investment, the better the conclusion of the design effect. The so-called saving investment, is relative to the construction project through the design of the specific function and use value, should be understood from the perspective of value engineering and whole life cost.

(4) Design work requires repeated coordination. First of all, the design of the construction project involves many different professional fields, which requires repeated coordination between the various professional design; secondly, in the design process, there is also repeated coordination between different design stages, which may be either between the same profession or between different professions; again, there is also a need for repeated coordination with external environmental factors, which mainly involves coordination with the owner's needs and the government's relevant departmental approval work coordination.

(5) The quality of design has a decisive influence on the overall quality of construction works. In the design stage, through the design work will be the quality requirements of the engineering entity, function and use of value quality requirements have been determined, the content of the project and the construction program are also very clear.

2. Construction stage characteristics

(1) construction stage is to implement the plan-based stage. Into the construction stage, the construction project target planning and planning work is basically completed, the rest of the main work is accompanied by the control of the plan to adjust and improve. Therefore, the construction stage is to implement the plan-oriented stage.

(2) the construction stage is to realize the value of the construction project and the use of the value of the main stage. The value of construction works is mainly formed in the construction process, including the transfer value and the value of living labor or added value.

Construction is the formation of construction engineering entity, realize the process of construction engineering value. Construction is based on the design drawings and design documents, the construction object from the idea into reality, from the "paper products" into actual, available construction material production activities.

(3) construction stage is the largest amount of capital investment stage. The formation of the value of the construction project is also the process of continuous investment of funds. Although the construction stage affects the degree of investment is only about 10%, but in order to ensure the quality of construction, to ensure the realization of the design of the function and the use of the value of the premise, there are still through the optimization of the construction program to reduce the consumption of physical labor and live labor, so as to reduce the possibility of investment in construction projects.

(4) the construction phase needs to be coordinated content.

(5) the construction quality of the overall quality of construction works to ensure the role. Whether the design quality can really realize, or how much it realizes, depends on the quality of construction. Construction quality is not only the realization of the design quality to play a role in ensuring that the overall quality of the construction project to play a role in ensuring.
