Triad Associates 11814 115th Avenue N.E. Kirkland, WA 98034 RE: SPECIAL INSPECTIONS, SPRINGBROOK VAULT, RENTON, WA JCL#96-054-100 Dear Mr. Fure: Enclosed please find a copy of all material submitted to us regarding special inspections by Cascade Testing on the above subject project. Please note Cascade Testing Laboratory, Inc.'s letter of October 14, 1996 is in error. All work did not "...conform to approved plans..." Specifically, slab and footing concrete identified in field report 85265 and cylinder report No. 26020 had a 28 day strength of 2,260 psi. Although a break at 56 day showed an increase in strength to 2,480 psi, the concrete design strength of 3,000 psi was apparently not provided for construction. In anticipation of some concern over this non-compliance with the approved plans, we are providing the attached check on the adequacy of the concrete used in construction. Our calculations show the concrete strength of fc = 2,480 psi will be sufficient to handle anticipated design loads. These calculations assume all other construction was performed in accordance with the approved plans. Please advise if you require additional information.
