Project control thoughts

Good project control implies both thought and action. It means... 

Operating Basis As the SIS engineering design nears completion, the resources and skills of plant operations should be considered. At some point, the SIS is turned over to operations and maintenance personnel, who must be trained on the new SIS and on their responsibilities. Consequently, thought should be given to the content and depth of the information that must be communicated to various personnel. This is especially important as the responsibility for the SIS transitions from the project team to operations and maintenance control. 

They have a much more powerful effect on data relevancy and validity than errors originating from sample or population variability. In fact, a thoughtfully conducted planning process takes into account the population variability at the project site, and errors originating from sample variability are controlled by the proper implementation of the field sampling procedures. 

When the gel time decreases toward half the time the pipe stays at one location, the uniformity of penetration can be remarkable (at least in these lab experiments). Figure 13.25 is an injection into stratified A, B, and C soils. The difference in penetration is less than 2, even though the permeability differences are about 30. Of course, in the field it is probable that improvements in uniformity of penetration do not match those obtainable under controlled laboratory conditions. Actually, uniform penetration is unattainable in most field projects. It should be thought of...
