PROJECT QUESTION: What is the reasoning behind requiring the cast-in-place temporary Type F barrier? Can an anchored portable precast concrete barrier be used instead?

Question: What is the reasoning behind requiring the cast-in-place temporary Type F barrier? Can an anchored portable precast concrete barrier be used instead?

Response: No. An anchored precast barrier requires a deflection zone behind the barrier that would encroach into the work zone. A cast-in-place barrier will be required since it does not require a deflection zone.
