Post-placement Tasks

Question 1
For a beam with a span exceeding 20 ft, how many days are the soffit forms required to remain in place in the absence of strength tests?
Active Guidance

Beam soffits with spans over 20 ft must remain shored for 21 days unless field-cured cylinder tests prove sufficient strength gain. Smaller spans of 10-20 ft typically only require 14 days. The 'at least' qualifier correctly identifies the mandatory minimum threshold for longer structural members.
