Changes orredirection in the design
26、 can be accommodated without extensive redesign at this point, thereby saving the owner/user/stakeholders time and money.4.3 During the earliest stages of design, refer to value analysis as value planning. Use the procedure to analyze predesigndocuments, for example, program documents and space plan

At the predesign stage, perform VA to define theprojects functions, and to achieve consensus on the projects direction and approach by the project team, for example, the owner,the design professional, the user, and the construction manager. By participating in this early VA exercise,
28、 members of the projectteam communicate their needs to the other team members and identify those needs in the common language of functions. Byexpressing the project in these terms early in the design process, the project team minimizes miscommunication and redesign,which are costly in both labor exp
