What happens if a precast concrete noise barrier panel is damaged?
If the precast concrete noise barriers are constructed from standard products readily available, then replacement is typically not an issue. However, when utilizing a custom design involving detailed form liners and integral color or stains, the issue becomes more critical. To address this concern, some agencies have instituted stockpiling policies where the contractor or precast concrete manufacturer, at the time of construction, supplies additional components to the organization responsible for maintenance. Typically, an additional 1 percent or 2 panels per 100,000 square feet may be supplied to the responsible organization for stockpiling purposes. The disadvantage to this practice is that the responsible organization may end up with a large amount of stock on hand.
