Concrete Foundation. (Tanks supported on concrete slabs)
Concrete Foundation a. All surface preparation will be conducted in accordance with the Steel Structures Painting Council Specification Surface Preparation Specification Number 13, SSPC-SP13 “Surface Preparation of Concrete”. An acceptable prepared concrete surface should be free of contaminants, laitance, loosely adhering concrete and dust, and should provide a sound, uniform substrate suitable for the application of protective coating or lining systems. All exterior concrete surfaces shall be power washed following a chlorine treatment as set forth in the Steel Structures Painting Council Specification Surface Preparation Specification Number 1, SSPC-SP13 “Concrete Preparation”. Power washing will be a minimum of 2000 PSI (at nozzle tip) to remove contaminants such as dirt, dust, mold, mildew, chalk and other foreign contaminants.
Concrete Foundation. The foundation shall be designed and constructed to safely and permanently support the structure. The basis of the foundation construction shall be consistent with the soils investigation data included herein at the end of these specifications. Appropriate changes to construction schedule and price will be negotiated if, during excavation, soil conditions are encountered which differ from those described in geotechnical report. The concrete foundation shall be constructed in accordance with ACI 301. Minimum concrete compressive strength shall be as specified in Section 03300, “Cast-In-Place Concrete”.
