Master plot plans

ISCO Chemical Company Ferrous Sulfate Recovery Plant Master Plot Plan... 

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. 

Reference Markers. Plant layout on the site requires a starting or reference point after the exact location of the property has been determined by permanent property markers already established or by independent survey of a local surveying firm. Markers are usually large-diameter capped steel pipe set in concrete, located outside the construction area, so that directional and elevation data can be taken relative to these permanent posts. One marker is called the zero corner point and all measurements start from there. Plant north and its relation to true north are next set up so that master plot plans can be oriented to the plant site and surveying stakes located in the working area. 

I thiiik it is important to make another general point about the innovation study. Uhile much work has gone into this stucfy, and there has been much public attention focused on it, it oust be viewed as only the opening skirmL in bat will be a long battle. We can t solve everything at once — we need to learn, and experiment. No one conceived and plotted the path of our previous innovative gains with any master plan, and it is unlikely that this will take place in the future.
