Technical change is also called engineering change, which has a broad meaning. Generally speaking, the technical changes in the construction process of an engineering construction project mainly include the following. ^[1]

No matter which party proposes a technical change, the engineer should issue a change instruction, and then the corresponding part of the original construction drawing can be modified according to the technical change clause in the contract. According to the "Construction Contract for Construction (Model Text)": "During the construction, the contractor must make a change to the original project design, and shall notify the contractor in writing 14d in advance. The change exceeds the original design standard or the approved construction scale At the time, the contractor should report to the planning management department and other relevant departments for re-examination and approval, and the corresponding design and drawings provided by the original design unit for the change. Due to the change, the contract price will increase or decrease, and the contractor will be damaged. The construction period shall be postponed accordingly. The contractor shall not alter the original project design during construction. The contractor shall bear the costs incurred by the contractor's unauthorized design change and the direct loss to the contractor, and the delayed construction period shall not be postponed " ^{[ 1]}

As technical changes will increase or decrease certain project subheadings or quantities, causing changes in project prices, affecting construction periods, and even quality, it will increase ineffective repetitive labor and cause unnecessary various losses. Therefore, designers and contractors The contractor has the responsibility to strictly control and minimize changes, which can be controlled from the following aspects. ^[1]

1. The approval right of the engineer should be reasonably limited ^[1]

1. For the construction unit, in the construction of the project, the project functions should be considered more comprehensively. Have a specific and accurate understanding of the project site, adjacent buildings, surrounding environment, hydrology, geological conditions, and traffic conditions to ensure that the design basis is accurate. The survey and design commission should be detailed and thoroughly mentioned. After the preliminary design is completed, it should be carefully reviewed before a formal construction drawing is formed. Reduce errors, reduce changes, pre-control changes, and save money. The losses caused by mistakes in the early stages of construction to the implementation stage are also amazing. ^[2]

2. For design institutes, drawings should be as complete and accurate as possible, and construction drawings should be issued after internal audit. Actively cooperate with and solve problems raised during the review and construction. Also pay attention to the drawings during the construction process, do not always know the problem passively. Minimize errors, reduce changes, and save money.

3. For the supervisor, the drawings should be read carefully, and the correct implementation of the drawings is also crucial. Changes and approval orders are now signed by the supervisor.

4. For the construction enterprise, the drawings must be familiar with repeatedly. After receiving the drawings, the drawing review will be done first, and a large number of problems will be resolved during the review. Before the construction, the drawings should be thoroughly understood and the problems should be mentioned before the facts. Make more safe, economical and convenient suggestions to make up for the lack of work of design and construction units and avoid losses.
