1、是否涉及到大规模的结构改动，结构改动越多，工期越长。比如是否要用钢结构搭两层，是否要浇筑混凝土楼梯，这需要足够的养护时间。
1, whether it involves large-scale structural changes, the more structural changes, the longer the duration. For example, whether to use the steel structure to build two floors, whether to pour concrete stairs, this needs enough maintenance time.
2、是否只能夜间施工，很多公共空间白天不允许施工，这需要把一些声音小的施工安排在白天，晚上加班加点做开槽之类的声音大的工作。夜晚施工，工人的效率必然会下降，也会增加工期。
2, whether only at night construction, a lot of public space in the daytime does not allow construction, this needs to make some small sound construction in the daytime, night overtime and other sound work. At night, the efficiency of workers will inevitably decrease and the construction period will also be increased.
3、物业的因素，进场施工需要物业审批，审批的进度也是工期的影响因素之一。
3, the property factor, enter the construction need property approval, approval progress is also one of the factors affecting the construction period.
4、节省时间要有严谨有效的工程组织安排，各项工作齐头并进，各项材料至少在是各种工序前备齐，能外加工的展柜、吧台、座椅等可以多选择外加工，进行成品定制，这是一个协调平衡的过程，防止窝工。
4, save time to have strict and effective organization of the project organization, all the work go hand in hand, the materials at least in the various processes before the preparation, can be processed outside the showcase, bar, seat and so on can choose the extra processing, finished product customization, this is a balanced process, to prevent working.
5、现场管理出效益，工人的督促管理，严谨拖延偷懒，工地的规划布置，材料与施工的位置距离等等
5, site management benefits, workers' supervision and management, rigorous delay and laziness, site planning and layout, material and construction location distance and so on.
6、工艺的复杂程度，人工花纹的雕刻是否繁复，吊顶的造型是否需要很多工时。
6, the complexity of the process, the complexity of artificial sculpture, whether the shape of the ceiling needs a lot of hours.
7、设计方案是否及时确认，中期方案更改的多少。
7, whether the design plan is confirmed in time, and how much the medium-term plan changes.
8、天气的原因，尤其是酷暑时因为施工工地还没有安装空调，导致工人工作效率降低。
8. The reason for the weather, especially during the heat season, is that the construction site has not yet installed air-conditioning, resulting in lower efficiency of workers.
9、面积的大小和工期并不完全成正比，麻雀虽小，五脏俱全，面积小同样需要各项工序，面积大只要工序协调进行，总工期也能适当压缩。
9, the size of the area and the duration of the work is not exactly proportional to the size of the sparrow, although the sparrow is small, full of five zang organs, small area also needs various processes, as long as the area is coordinated, the total time limit can be properly compressed.
