A general contractor discovers that concrete delivery is delayed by 2 weeks due to supplier issues. The concrete work is on the critical path and scheduled to start in 1 week. What is the best expediting strategy?
Correct Answer
D) Source concrete from multiple suppliers to meet the original schedule
Since the concrete work is on the critical path, the contractor should expedite by sourcing from multiple suppliers to meet the original schedule and avoid project delays. This maintains the critical path timeline.
Why This Is the Correct Answer
Option B is correct because when work on the critical path is threatened by delays, the primary strategy should be expediting to maintain the original schedule. Since concrete work is on the critical path, any delay will directly impact the project completion date. Sourcing from multiple suppliers is a practical expediting technique that can resolve the supply issue while keeping the project on track. This approach addresses the root problem (supplier delay) while maintaining schedule integrity.
Why the Other Options Are Wrong
Option A: Accept the delay and adjust the entire project schedule
Option D is wrong because delaying critical path activities automatically delays the entire project. While focusing on other activities might seem productive, it doesn't solve the fundamental problem and will still result in overall project delay.
Option C: Substitute with a different foundation system
Option A is wrong because accepting delays on critical path activities automatically extends the entire project duration. This should be a last resort after all expediting options have been exhausted, as it impacts project delivery commitments and may result in liquidated damages.

Think 'Critical = Can't Wait' - critical path activities must be expedited, not delayed or substituted
