Analysis on the Importance of Preliminary Work based on Engineering Fixity Yanting Ma1,a, Chunjie Ma2,b 1,2Institute of civil engineering, Zhejiang University, Hangzhou, China atina.margaret@163.com, b13905742430@139.com Keywords: Engineering fixity, Preliminary work, Construction organization method, Project Management Body of Knowledge (PMBOK) Abstract.
On the one hand, construction personnel, building materials, machinery and equipments flow with different engineering locations, and new production preparation conditions need to set up with every change of a construction site.
Engineering fixity works on project overall arrangement For project formation and overall arrangement, through the study of the characteristics of engineering fixity, the construction unit can estimate the amount of necessary labor and material resources as well as the construction schedule more accurately, and make full use of the existing resources.
The list of project participants is a file also full of engineering fixity, which contains a list of all project-related personnel and their contact information, like residents around the site (there will be a certain probability of interference by construction), relevant government staff (to play a key role in the issuance of building permits), etc.
