【 Weak current College 】 how to control the design change?

Construction unit in the project accounts, only to find the project cost is far exceeding the project budget. And then go back to look for cost reasons, increased significantly, it is in large part because of the engineering process of design changes. While the causes of these design changes, what is it?

Design change main causes:

1. proposed by the construction unit

Construction units often because during construction construction site found out, the part not imagine then look good, so practical and propose design changes; sometimes as tenants, user request design changes; sometimes initially did not consider satisfactory; there is construction, supervision, design units made a few design changes; sometimes also due to underground geological conditions, weather, accidents, etc make design changes, thus ensuring the smooth completion of construction.

2. the construction unit made

Construction units will be in constant construction, materials can not buy, weather, and even to can save money for the construction units and other reasons and design change requests.

Construction units may also be because construction mistakes and design change requests, tasks have been completed buildings.

3. Design Unit

The original design drawings and omissions, the figure does not pass, the relevant government departments of the drawings do not meet the specifications and requirements and design units for design changes.

4. surveillance, reconnaissance units proposed design changes

Sometimes supervision will make some design changes, construction, exploration will during construction since the original investigation has found no issues and change requests.

5. other construction unit made

During construction, General construction will have multiple units involved in the construction, there is a possibility that a professional conflicts with collision phenomena, in order to facilitate the construction, some construction units will make this professional or other professional design change requests.

How to reduce construction design change?

1. to investigate the design front, housing requirements correctly complete carefully.

2. design units relative to give sufficient time for them to meet construction requirements of the finished drawings. Drawings in order to achieve the design depth specification and construction requirements.

3. carefully examining figure, on the one hand you want to submit to the Tribunal all graph drawing review units, meet the requirements of the relevant departments; on the other hand the construction units to serious amounts of figure, ensure that the drawings accurately express the intention of building construction units and few errors.

4. before the commencement of the construction of the professional team of hearing good figure, put some construction challenges, somewhere in the conflict to come before construction, and develop solutions.

5. decrease in errors in the construction process.

6. measures for design changes, there is a very important, is rarely out of the design changes. Design change volume is the geometric form of growth, there is a vicious circle of cumulative effects. Even if it is a design change, nor to the construction works volume increased by visa in order to control the amount of design change.
