Structural steel estimating procedure

Structural Steel - Use procedure in Section 19.3 to develop take-offs and cost. Break down by structures and pipe racks and don t forget to identify and estimate miscellaneous service ladders and platforms related to specific equipment items. 

Concrete and Structural Steel quantities can be easily checked with the quick estimating procedures in Chapter 19. 

This procedure is used to estimate the weight, fabricated cost, and erection hours of the various types of steel structures required in a chemical plant. It is a very good tool for checking contractors take-offt and estimates as well as discussing and evaluating field extras. 

Other workers have published improved procedures for inspecting both reinforced concrete and prestressed concrete structures with regard to determination of the embedded steel components [110]. A prototype ultrasonic procedure was developed to determine the condition of prestressed and pretensioned tendons in concrete. The application of electrochemical surface-mounted systems for estimating the rate of corrosion of reinforcing steel and other embedded steel components in large concrete structures was described using this technique.
