According to CalTrans, braces from each lot must be tested up to which number?

• A. 100
• B. 250
• C. 500
• D. 750

Answer: (C)

The main idea here is about quality control through sampling. Caltrans sets a cap on how many braces from each lot must be tested to verify that the batch meets strength and fabrication standards. Why this cap matters: you want enough samples to reliably catch a batch that’s out of spec, but you don’t want to slow down the project by testing every single brace. A testing limit that’s substantial enough gives you confidence that the lot is consistent, catching systemic issues like weak material or improper workmanship, while keeping inspections manageable for the crew. In practice, this approach means you’re not relying on a single brace to judge a whole lot, nor are you wasting time testing more than is useful. The chosen limit reflects a balance between detecting defects and maintaining a reasonable workflow. The other options would either under-sample, risking missed defects, or over-sample, adding unnecessary cost and delay.
