Secondly, splitting the model according to the subsection and the item; and when the model component is named, the actual attribute of the component is consistent with the type name of the component.
Thirdly, dividing the horizontal and vertical positions of the BIM structural model according to the structural characteristics and the structural type of the project; the floors at the bottoms of the assembled building columns are vertically divided, and the cast-in-place concrete part is divided according to the floors; dividing the horizontal position according to a dividing mode designed by a construction organization and combining the number of the sub-packages; performing work task decomposition according to the granularity of the work task of the analysis project, and compiling a total schedule of the Vico Office; and performing team-level construction procedure simulation in a linear progress plan mode.
For the third step, the main contents of work task decomposition comprise work task name writing, project amount correlation and work efficiency filling; and decomposing the granularity of the progress analysis corresponding to the labor yield in the later period by the work task. Compiling a site construction progress plan according to the design requirements of the model; the labor conditions of the site comprise teams, work efficiency and manual information; and (5) making a project amount statistical table.
In the embodiment, a Vico Office total progress meter is compiled into a key task for analyzing a key route, namely restricting the whole construction progress; wherein, the large-scale mechanical equipment fully meets the requirements of site construction and is used as a key line according to the process with the longest time consumption; the hoisting capacity of the tower crane can be used as a key factor temporarily at the stage of large hoisting machinery with large hoisting frequency requirement. Establishing a logical relationship among the work packages, and further determining the number of work shifts, the number of workers and an efficiency factor; and adjusting work groups, number of people and efficiency factors to ensure that the total construction period is consistent with the plan when the total construction period does not meet the plan requirement.
Three basic ways of ergonomics: adjusting an efficiency factor: the reason for adjusting the efficiency factor is mainly that the efficiency factor is applicable to different space environments and different position environments at the same time and the same work and the same construction team. Team consumption (number of work groups): the team consumption adjustment is mainly to adjust the number of working groups, and when the construction period is short, the progress can be guaranteed by increasing the number of groups. The method is applicable to the condition that the working face permission and the labor resource can be guaranteed. Consumption: the consumption is the work efficiency adjustment which is the core of labor productivity, the consumption adjustment can achieve the effect of pulling and moving the whole body, and the consumption adjustment is an effective means for improving or balancing the production efficiency of a construction site; the process of consuming continuous adjustment is also a necessary way for the establishment of the enterprise rating library and the construction rating library. The final goal of work efficiency optimization is to serve construction enterprises to organize production to achieve cost reduction and efficiency improvement effects, and work efficiency optimization is from the site and controls the site.
In the embodiment, the working procedures in the key line are calibrated and controlled every day, and the working procedures on the non-key line are paid stage attention; wherein individual module processing and output of quantification tables and correction tables are performed for project time, teams, materials and machines in the critical line.
And step four, acquiring data by adopting an intelligent construction site management platform and a digital asset management platform to obtain the work efficiency of equipment and various work classes and groups. The intelligent construction site management platform is used for performing integrated platform management on each management data and data generated in the construction process; the digital asset management platform is used for displaying required resources, manpower and the like in a data mode and performing Internet platform management. This way, it is beneficial to control the construction progress and consumption in real time. In the fabricated engineering, the working value of each team on the construction working surface is measured by adopting data collected by front-end equipment of a smart construction site and the frequency of the hanging times of the tower crane.
In the fourth step, the team efficiency is optimized, the technical route of the work efficiency optimization is to adjust the construction and production organization mode, and the progress deduction is carried out by selecting the construction organization modes such as sequential construction, parallel construction, flow construction and the like according to the actual situation on site; adjusting the flow section and the construction layer according to the condition of the sub-package team and the distribution condition of the engineering quantity; and adjusting work efficiency, namely adjusting the work efficiency of each process according to experience and actual on-site progress conditions to ensure the total construction period.
And step five, adjusting the interval value of the work efficiency of the team in BIM software, and generating a curve by the linear progress plan.
As shown in fig. 7, the construction sequence of the PC member is linear, and includes steel bar installation, prefabricated floor installation, formwork installation, cast-in-place concrete wall, beam, column, and floor slab in sequence; the time required for planning each construction process is clarified by dividing different floors and dividing the same floor into A, B construction zones.
Step six, taking the cell as a unit, and adjusting the crossed curve to be zero crossing; and sequentially adjusting subsequent processes and resources without repetition or interruption in the same time period.
As shown in fig. 8, the actual construction time of the construction process is recorded as the process progresses, and the start time of the subsequent process is automatically predicted. In the figure, the scheduled starting time of installing the precast floor slab in the 5-storey A area is 2018.1.21, and the actual time is 2018.1.20 for starting construction, which is 1 day ahead of the scheduled starting time, so that the starting time of future tasks is influenced; due to the increased efficiency of 'installing precast floor slabs', the required time for the PC components is changed when the task starting time is predicted to start 1 day ahead of the original plan in the 6-storey A area.
