【 Weak current College 】 construction drawing design change reason

Design change proposed by the premises Design Institute, map units, building, construction unit, sometimes including supervision units and quality supervision departments. The real reason for the design change, but only the summary of the following:

1. increase or decrease in engineering content

Changes in the project content, may be due to the need to increase the number of auxiliary facilities, capabilities increase's needs.

2. technology, changes in the use of functional requirements

Some of the production process, lifestyle and use features will increase in the construction process or change, turn on engineering content made the change request.

3. marketing requirements

During construction, particularly local or partially completed, after the entity's observation and experience, find some constructs and does not look good or inconvenience and, therefore, improve the design change requests.

4. examination of figure requirements

Audit diagrams construction drawings will be to identify some does not satisfy the standard requirements of local, designed to meet the audit requirements of figure qualified, so going to make design changes. Audit plan including construction drawing examination, construction drawing examination of planning, audit, fire, electricity, water supply and drainage construction audit, gas, Air Defense Review Tribunal and lightning protection Tribunal. Now also more energy-efficient audit diagram.

5. design errors, or omissions

Construction drawing of design errors, or omissions is a good thing, in construction will often be found. When you encounter this problem when you are designing corrections and additions.

6. the rationalization proposals

Into account in the construction process of the construction convenience, cost savings, material replacement, etc. will make some design changes.

7. construction errors

When a construction errors, some need to remove a bad; some of it is not possible to dismantle, then it can only be a bad bargain, reduce losses, the completed portion. In such cases, it will change the design parameters, the adjustment is not part of the construction of the blueprints to rectification.

8. equipment and material supply to meet the needs of design

Sometimes the design of the required material not only finding substitute products, which will change the design.

9. external environment changes

Due to the duration of delay, hurry need, such as when the weather changes and adjustments to the original design of the technological requirements and material requirements, and even the structure of the dimension.

Before construction due to the collected data is inaccurate and design changes. As exploration data and geological conditions.

10. construction craft requirements

When some widget cannot or present construction technology, construction equipment construction condition cannot, or will require the design change, thus ensuring the smooth progress of the construction.
