Ladd Canyon Salt Shed Foundation Plan.pdf

This is a structural foundation plan set from the Oregon Department of Transportation for the Ladd Canyon Stockpile Storage Facility located in Union County, Oregon. The project involves construction of a 60' x 100' bulk material storage facility for sand and/or salt storage, designed according to the 2014 Oregon Structural Specialty Code. The structure is specified as a pre-fabricated Acusteel fabric covered building with a maximum height of 32 feet, one story, and 6000 square feet of space. The building includes basic utilities but is designed as an unheated, non-cooled structure without fire suppression systems or plumbing fixtures.

The foundation design specifies precast concrete blocks with f'c of 4000 PSI, utilizing "Ultra Block" interlocking type blocks with standard grade finish. The foundation is designed for 1500 PSF allowable soil bearing pressure with a coefficient of sliding friction of 0.40. Steel connection hardware must be galvanized per ASTM A123 with G90 coating, including threaded rod anchors meeting ASTM A307 Grade 36 specifications. Special inspections are required for epoxy installations and post-installed anchors, with all work needing to comply with ODOT specifications and approved ESR reports.
