Layout planning

With more and better information regarding the process and layout plans, estimating engineers can prepare detailed estimates which are often quite accurate, usually 10 percent for the best. It is the duty of the process designer to supply the best information in order to contribute to better or improved estimates. 

Layout planning involves knowledge of a wide range of technologies that will extend beyond those of individual planners and the full range of expertise may not exist in a production facility. Consultants can provide the expertise but guidance can be found in the published works listed in the References. 

The project plan should be started as soon as possible so that all aspects of the early layout planning can be incorporated into the plan. 

In the discussion of process and equipment design given in the previous chapters no reference was made to the plant site. A suitable site must be found for a new project, and the site and equipment layout planned. Provision must be made for the ancillary buildings and services needed for plant operation and for the environmentally acceptable disposal of effluent. These subjects are discussed briefly in this chapter.

Unit Areas Concept. The basic blocks with which to build an arrangement for plot plans are often used in the unit area concept. This method of planning is particularly well adapted to large plant layouts. Unit areas are often delineated by means of distinct process phs s and operational procedures, by reason of contamination, and by safety requirements. Thus, the delineation of the shape and extent of a unit area and the interrelationships of each area in a master plot plan is one of the first tasks of layout planning. Figure 5-1 is an example of this type of planning.
