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.
Use orange
mesh safety fence meeting the requirements of Article 4188.03.
1. Road
Closures.
a. Place a fence meeting the
requirements of Article 2518.02 across the roadway from outside edge of
shoulder to outside edge of shoulder. Securely support the fence so it is in a
vertical position without sagging.
b. Place a Type III barricade,
described in Part 6 of the MUTCD, immediately in front of the fence at the
approximate roadway centerline. Mount a ROAD CLOSED (RII-2) sign on the Type
III barricade.
c. In lieu of Articles 2518.03, A, 1, a and b above, place a series of
Type 3 barricades across the roadway from outside edge of shoulder to outside
edge of shoulder. Ensure that gaps between Type 3 barricades are no greater
than 6 inches. Mount a ROAD CLOSED (R11-2) sign over the top two rails of on
the Type 3 barricade located closest to the approximate roadway centerline.
d. Erect road closures as specified
in the contract documents. Erect them 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.
e. Erect road closures beginning
with the start of the contract period as specified in the contract documents,
or when the work commences.
2. Hazard
Closure.
a. Place a fence meeting the
requirements of Article 2518.02 across the roadway from outside edge of
shoulder to outside edge of shoulder. Securely support the fence so it is in a
vertical position without sagging.
b. Place a Type III barricade,
described in Part 6 of the MUTCD, immediately in front of the fence at the
approximate roadway centerline.
c. In lieu of
Articles 2518.03, A, 2, a and b above, place a series of Type 3 barricades
across the roadway from outside edge of shoulder to outside edge of shoulder.
Ensure that gaps between Type 3 barricades are no greater than 6 inches.
d. Erect hazard closures as
specified in the contract documents. Erect them at locations within a work area
when construction involves major hazards on existing or relocated roadways.
Such hazards may be located at streams, gullies, railroads, bridge approaches,
and driveway locations. Through public traffic should not normally encounter a
hazard closure.
e. Erect hazard closures beginning
with the start of the contract period as specified in the contract documents,
or when the work commences.
1. Maintain 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 is responsible for the restriction of public traffic into
the closed area.
2. 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.
3. The Engineer will notify the
Contractor of the date of removal of safety closures. The safety closure
remains 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.
2518.04 method of measurement.
The
Engineer will count each Safety Closure (either road closure or hazard closure)
erected.
A. Payment will be the contract unit
price for each Safety Closure counted.
B. Payment is full compensation for
furnishing all material, labor, and equipment necessary to erect, maintain, and
remove the Safety Closure, unless indicated otherwise in the contract
documents.
