How to control project cost in construction and design change

Some construction enterprises take advantage of the nonstandard issuance and management of some construction units. For example, some construction units examine and approve the representatives of construction units beyond their authority, there is no feasible internal control procedure to ask the leaders for examination and approval step by step, and the representatives of construction units lack the awareness and quality of visa price control and are irresponsible for visa work. , and often use the latter transfer process to communicate actively, using their own professional and technical advantages to confuse the construction unit and increase the project cost. Design changes should be made as soon as possible, and the earlier the changes, the smaller the losses. If it is changed in the design stage, only the drawings need to be modified, and other expenses have not yet occurred, so the loss is limited; If it is changed in the procurement stage, not only the drawings need to be modified, but also the equipment and materials need to be re-purchased; If changes are made in the construction stage, in addition to the above expenses, the projects that have already been constructed need to be demolished, which will inevitably lead to greater change losses. Therefore, the design changes should be strictly controlled, and the changes should be controlled in the early stage of the design stage as far as possible, especially the design changes that have a great impact on the project cost should be accounted for first and then changed. After the design changes, the audit is more important. No matter where the design change is proposed, the supervision department should negotiate with the construction unit, design unit and construction unit. After confirmation, the design department will issue a notice and the supervision engineer will sign it for implementation. Design changes should be true. The original design can't guarantee the quality requirements of the project, and the construction can't be carried out due to design omissions and errors and inconsistent site. Therefore, in the construction process, the construction unit should strictly review the design change visa. By changing the design, adding projects or raising the price, the construction unit not only carries out normal engineering construction according to the contract provisions and design requirements, but also uses the defects and bidding skills found in the bidding documents and design drawings to increase profits through design changes. Design changes, especially those beneficial to the construction unit, are an important means for the current construction enterprises to create profits.
