2518.01 DESCRIPTION.
This section concerns Safety Closures erected as specified in the contract documents. Two types of safety Closures will be specified: Road Closures and Hazard Closures.

A. Road Closures.
A road closure shall consist of an orange mesh safety fence, meeting the requirements of Article 4188.03, placed across the roadway from outside edge of shoulder to outside edge of shoulder. The safety fence used in this situation shall be securely supported so the fence is in a vertical position without sagging. A type III barricade as described in Part VI of the MUTCD shall be placed immediately in front of the orange mesh safety fence at the approximate roadway centerline. A ROAD CLOSED (R11-2) sign shall be mounted over the top two rails of the Type III barricade.

The Contractor shall erect road closures as specified in the contract documents. Road Closures shall be erected on the mainline of the roadway where public traffic is diverted onto an on-site detour and where public traffic is prohibited from entering the work area. The Contractor shall be responsible for erecting road closures beginning with the start of the contract period as specified in the contract documents, or when the Contractor commences work.

B. Hazard Closure.
A hazard closure shall consist of an orange mesh safety fence, meeting the requirements of Article 4188.03 placed across the roadway from outside edge of shoulder to outside edge of shoulder. The safety fence used in this situation shall be securely supported so the fence is in a vertical position without sagging. A Type III barricade as described in Part VI of the MUTCD shall be placed immediately in front of the orange mesh safety fence at the approximate roadway centerline.

The Contractor shall erect hazard closures as specified in the contract documents. Hazard closures shall be erected at locations within a work area when construction involves major hazards on existing or relocated roadways such as at streams, gullies, railroads, bridge approaches, and driveway locations. Through public traffic should not normally encounter a hazard closure. The Contractor shall be responsible for erecting hazard closures beginning with the start of the contract period as specified in the contract documents, or when the Contractor commences work.

2518.02 ERECTION AND RESPONSIBILITY.
The Contractor shall be responsible for maintaining the location and condition of the safety closures. Any Contractor who temporarily moves the safety closure for equipment or delivery of materials, shall replace it in its original position and be responsible for the restriction of public traffic into the closed area.

If a safety closure placed by the Contractor is required for an area after the Engineer's approval of completed work for that specific area, maintenance of that safety closure will become the responsibility of the Contracting Authority. The Engineer will document in writing the transfer of authority.

The Engineer will notify the Contractor of the date of removal of safety closures. The safety closure shall remain the property of the installing Contractor. If the safety closure is not removed by the date specified in the notification, it will become the property of the Contracting Authority and the Contractor will be charged for any removal costs.

2518.03 METHOD OF MEASUREMENT.
The Engineer will measure, by count, each Safety Closure (either road closure or hazard closure) erected.

2518.04 BASIS OF PAYMENT.
For each Safety Closure counted, the Contractor will be paid the contract unit price. This payment shall be full compensation for furnishing all material, labor, and equipment necessary to erect, maintain, and remove the Safety Closure, unless otherwise indicated in the contract documents.
