Why This Is the Correct Answer
A201 requires notice and evaluation for concealed or unknown conditions before adjustments are resolved.
Why the Other Options Are Wrong
Option A: Remove it without notice and claim extra payment at final completion, while relying on a meeting agenda instead of a contract instrument
Remove it without notice and claim extra payment at final completion, while relying on a meeting agenda instead of a contract instrument skips the written authority, scope, price, notice, or release control needed for concealed conditions.
Option C: Treat it as a bid addendum even though bids are closed
Treat it as a bid addendum even though bids are closed skips the written authority, scope, price, notice, or release control needed for concealed conditions.
Option D: Ask the lowest earthwork bidder to decide the owner adjustment
Ask the lowest earthwork bidder to decide the owner adjustment skips the written authority, scope, price, notice, or release control needed for concealed conditions.
