【摘要】 近年来,越来越多的住宅项目采用装配式工艺建造。鉴于住宅项目工期长、分工协作程度高,施工过程中受到环境变动、工序繁复和多工种交叉作业的显著影响,导致施工进度时常面临滞后和交付延期的风险。因此,传统的施工进度管理方法已经无法有效管控装配式住宅项目施工进度,迫切需要优化施工进度管理方法来实现装配式住宅项目的进度管控。首先,本文以Y装配式住宅项目作为研究对象,对项目施工进度实施情况进行了分析,发现实际进度滞后47天,滞后原因之一是施工关键路径把握不清,因此亟需对项目的施工进度进行优化。其次,本文采用关键链法,以最低限度延长整体项目工期为目标,构建了关键链优化模型和缓冲区设置模型,运用上述模型对项目关键路径进行了优化和对缓冲区进行了设置,进而编制了优化后的施工进度计划。然后,运用BIM技术构建了项目的三维施工模型,并与优化后的施工进度计划进行关联,完成了BIM-4D施工模型构建,将实际进度数据与模型关联,构建了BIM-4D实时模型,基于上述模型对项目的进度偏差与调整展开了分析。接着,基于BIM-4D实时模型搭建了BIM-4D施工进度管理平台,并将实时采集到的实际施工进度信息导入平台,进而不断对项目实际进度状态进行分析和调整。最后,项目经历了624日历天后正式交付,比原计划工期625天提前1天,实现了施工进度管理的目标,并从管理、组织、技术和经济四个方面制定了相应的保障措施,分析了可视化施工进度管理成效。通过针对Y装配式住宅项目施工进度管理进行研究和分析,所制定的施工进度管理方法与措施具有一定的科学性、适用性与可推广价值,能为其他装配式项目施工进度管理予以经验借鉴和有益参照。图43幅,表13个,参考文献86篇。更多还原

【Abstract】 In recent years,an increasing number of residential projects have been constructed using prefabricated techniques.Due to the long construction period and high level of division of labor and cooperation in residential projects,the construction process is significantly affected by environmental changes,complex processes,and cross operation of multiple trades,resulting in the risk of delayed construction progress and delivery delays.Therefore,traditional construction progress management methods are no longer effective in controlling the construction progress of prefabricated residential projects,and there is an urgent need to optimize construction progress management methods to achieve progress control of prefabricated residential projects.Firstly,this article takes the Y prefabricated residential project as the research object and analyzes the implementation of the project’s construction progress.It is found that the actual progress is delayed by 47days,and one of the reasons for the delay is the unclear grasp of the key construction path.Therefore,it is urgent to optimize the construction progress of the project.Secondly,this article adopts the critical chain method,with the goal of minimizing the overall project duration,and constructs a critical chain optimization model and buffer setting model.The above model is used to optimize the project’s critical path and set the buffer zone,and then the optimized construction schedule is formulated.Then,BIM technology was used to construct a three-dimensional construction model of the project,which was correlated with the optimized construction schedule.The BIM-4D construction model was completed,and the actual progress data was correlated with the model to construct a real-time BIM-4D model.Based on the above model,the progress deviation and adjustment of the project were analyzed.Subsequently,a BIM-4D construction progress management platform was built based on the BIM-4D real-time model,and the real-time collected actual construction progress information was imported into the platform,continuously analyzing and adjusting the actual progress status of the project.Finally,the project was officially delivered 624 calendar days later,one day ahead of the original planned construction period of 625days,achieving the goal of construction schedule management.Corresponding guarantee measures were formulated from four aspects:management,organization,technology,and economy,and the effectiveness of visual construction schedule management was analyzed.Through research and analysis on the construction schedule management of the Y prefabricated residential project,the developed construction schedule management methods and measures have certain scientific,applicable,and promotable value,which can provide experience and useful reference for the construction schedule management of other prefabricated projects.43 images,13 tables,and 86 references.更多还原
