一般来说，加快进度、缩短工期需要增加投资（成本），加快工程进度可能影响

In general, speed up the progress, shorten the duration of the need to increase investment (cost), to speed up the progress of the project that may affect the quality of the project, strict quality control standards may also affect the progress of the project. Therefore, prior to the preparation of project schedule must first develop practical scientific progress of the plan, there must be a certain degree of predictability and forward-looking, must fully understand the goals of the project cost control and quality control in the preparation of project schedule.

In general, speeding up the progress and shortening the schedule requires increased investment (cost), speeding up the project may affect the quality of the project, and strictly controlling quality standards may also affect the project progress. Therefore, before preparing a project schedule, a realistic scientific schedule must be developed in advance, a certain degree of predictability and forward-looking ness must be made in the preparation of the project schedule, and the objectives of project quality control and cost control must be fully understood.

Generally speaking, to speed up the progress and shorten the construction period needs to increase investment (cost). Speeding up the project progress may affect the project quality, and strict control of quality standards may also affect the project progress. Therefore, before preparing the project schedule, it is necessary to make a feasible scientific schedule in advance. When preparing the project schedule, it is necessary to have certain predictability and foresight, and fully understand the objectives of project quality control and cost control.
