Why is a short-interval look-ahead schedule used during construction?
Correct Answer
D) To coordinate near-term constraints, crews, materials, and inspections.
Look-ahead planning turns the master plan into near-term coordination and constraint removal. It does not waive contract controls.
Why This Is the Correct Answer
Look-ahead planning turns the master plan into near-term coordination and constraint removal. It does not waive contract controls.
Why the Other Options Are Wrong
Option A: Use look-ahead planning to replace the master schedule permanently
The trap in A is To replace the master schedule permanently. That selection is wrong because the option tries to substitute, waive, or delete the Look-ahead planning control; the item instead requires To coordinate near-term constraints, crews, materials, and inspections.; Look-ahead schedules coordinate near-term constraints and work readiness.
Option B: Use look-ahead planning to waive permit inspections
Choice B gives To waive permit inspections. Its specific error: it removes the controlling Look-ahead planning requirement instead of meeting it.
Option C: Use look-ahead planning to approve substitutions without review
Choice C (To approve substitutions without review.) is rejected because the action skips the timing, documentation, or field-control step needed for Look-ahead planning.
Memory Technique
Make look-ahead planning a purpose cue; if the choice changes the purpose, it cannot be To coordinate near-term constraints, crews, materials, and inspections.
