[0070] Step 3: Preset the deviation level threshold set; according to the deviation level threshold set and progress deviation indicator Determine the construction progress deviation level and determine the construction progress adjustment method based on the construction progress deviation level.

[0071] Step 3 includes the following steps: Step 301: The method for determining the construction progress deviation level is: Deviation level threshold set includes high deviation level threshold and low deviation level threshold .

[0072] It should be noted that the high deviation level threshold and low deviation level threshold The method for determining the high deviation level is to collect historical data from the construction projects completed by the enterprise in the past and calculate the progress deviation index according to the above method, screen out the higher 20% progress deviation index and calculate its average value as the high deviation level threshold The reference value is used to screen out the lower 20% progress deviation indicators and calculate their average value as the low deviation level threshold reference value.

[0073] Deviation indicators based on deviation level thresholds and progress The standards for judging the construction progress deviation level are: When the construction progress deviation level is a high deviation level, the adjustment method is: hold an emergency meeting to clarify the specific reasons for the deviation and adjust the technical plan, strengthen communication and collaboration between construction teams, and promptly resolve problems arising in cross-operations through daily short meetings or on-site exchanges. According to the actual progress, dynamically adjust the short-term construction plan. For example, if it is found that the progress of some construction processes is lagging behind in a certain week, promptly adjust the construction plan for next week, increase resource input or optimize the construction sequence.

[0074] When the construction progress deviation level is a medium deviation level, the adjustment method is: analyze the construction processes that are lagging behind in progress, and rationally deploy labor from construction areas that are ahead of schedule or relatively loose to lagging areas. At the same time, project management personnel must strengthen the tracking and management of the construction progress, and promptly discover and resolve problems that arise during the construction process.

[0075] When the construction progress deviation level is a low deviation level, the adjustment method is: strengthen the daily maintenance of construction equipment, ensure that the equipment is in good operating condition, improve the utilization rate of equipment, make appropriate adjustments to personnel tasks based on the skills and work efficiency of construction personnel, and assign personnel with high work efficiency to progress-critical activities.

[0076] Combined with the content of step 301: Deviation indicators based on deviation level thresholds and progress Judging the deviation level of construction progress is conducive to accurately determining the degree of deviation. Determining the construction progress adjustment method based on the deviation level of construction progress will help to reasonably allocate resources and make the adjustment measures more in line with the actual situation.
