ABSTRACT

If details are available, make rough take-offs and use prices in Section 19.3. If not, make an allowance consistent with the factors in Chapter 10. Concrete - Use procedure in Section 19.3 to develop take-offs and cost. Break down as many items as information permits. 1. Equipment - by item. 2. Structure Foundations - per structure. 3. Floor Slabs - per areas. 4. Dikes - per dike. 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. Buildings - Identify and estimate the shelter (roof and siding) requirements for process structures as well as the area of buildings included in the Scope of Work. Use unit prices in Section 19.3 to estimate costs. Insulation - The take-offs for piping insulation are developed as part of the piping account estimate. The take-offs for equipment insulation are developed by identifying and estimating the outside area of those items requiring insulation. The unit prices in Section 19.5 are used to estimate cost.
