API 650 Foundation Tolerances
API 650 Foundation Tolerances
(OP)
I am designing a cylindrical water tank with a concrete ring beam. I am attempting to conform to the standards of API and would like to incorporate the subgrade preparation requirements in my specifications. I have portions of the API 650 that reference Section 5.5.6, which I do not have. This section is referenced in Appendix B under B.4.2 "Earth Foundations with a Ringwall". It specifically states, "Tank foundations must be true to the specified plane within the tolerances specified in 5.5.6". What are these tolerances?

A comprehensive text discussing all aspects of aboveground storage tanks. Topics include codes & standards, materials, corrosion, foundations, seismic concerns, roofs, fire protection, emissions, inspections, and settlement. An excellent reference for those unfamiliar with certain aspects of tanks.

Also - why not use AWWA specifications?
