Delivery Methods That Drive Durable Concrete Repairs
Durability can be shaped before construction begins. This presentation compares design-bid-build, construction manager at risk, and design-build through case-based examples, focusing on how each method affects investigation completeness, decision speed, constructability, risk allocation, and the ability to respond to unknown conditions. The practical conclusion is to align the delivery method with uncertainty and execution constraints so repair decisions can evolve without sacrificing long-term performance.

Anchorage decisions often determine whether a repair detail is practical, code-compliant, and capable of transferring load into existing concrete. Presented with Luis R. Pelayo, PE, SE, this session connects code and qualification requirements to the realities of existing members: uncertain geometry, reinforcement congestion, edge distance, concrete condition, installation access, and temporary loading. The case studies show how those constraints shape partial-depth repairs, section enlargement, and full replacement.

Pull-off testing appears straightforward, but applying it inside a nuclear quality program requires much more than a test procedure. This presentation examines how acceptance criteria, work sequencing, performer qualification, documentation, and communication interact when concrete repairs affect regulated structures. Three lessons learned show why variable test results need clearly defined response paths—and why ambiguity can turn a field issue into a project-wide delay.
