HOAG, Ancillary Emergency Building

Twining was tasked with developing the materials testing program and providing a condition assessment for this project. Our scope of services consisted of:

Materials Testing Program:

• Performing GPR to locate reinforcing steel prior to core drilling and coupon extraction
• Providing a Project Engineer to oversee the sampling, documentation and custody of concrete samples and steel coupons
• Extracting cores for compressive strength, density, and modulus of elasticity per ASTM C39, C42, C469
• Extracting cores for compressive to be use as a control core to determine the 40% of the ultimate strength prior to testing for MOE
• Extracting steel coupons for Yield/Tensile Strength2 and Chemical Analysis3
• Extracting cores for splitting tensile strength
• Extracting web coupon at select locations for Yield/Tensile and Chemical Analysis

Condition Assessment:

• Provide visual verification of existing building components per Exhibit A: “Condition Assessment Criteria” and Section 4.1 “Condition Assessments of Concrete Elements”
