814.01 Description. This work shall consist of furnishing and installing or
constructing a handhole, a heavy-duty handhole, or a double handhole.
814.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Coarse Aggregate for French Drains (Note 1) ................................... 1004.05
b.Portland Cement Concrete (Note 2) ....................................................... 1020
c.Composite Concrete Handhole (Note 3) ............................................ 1088.05
d.Handhole Frame and Cover .............................................................. 1088.06
e.Precast Concrete Handholes ............................................................. 1042.17
f.Preformed Expansion Joint Fillers .......................................................... 1051 Note 1. Gradation CA 5 or CA 7 shall be used. Note 2. Class SI concrete shall be used. Note 3. Hardware used for assembling a composite concrete handhole shall be hot-dip galvanized or stainless steel in accordance with Article 1088.03. CONSTRUCTION REQUIREMENTS
814.03 Construction. The location of the handhole shall be excavated so
that the top of the handhole is set flush with the sidewalk or paved surface. When installed in earth shoulder away from the pavement edge, the top surface of the handhole shall be 1 in. (25 mm) above the finished grade. The excavation shall be deep enough to accommodate the depth of the box and french drain. The french drain shall be constructed underneath the proposed handhole according to Article 601.06. Art. 814.03 Gulfbox Junction Handholes shall be constructed as shown on the plans and shall be cast-in- place, composite concrete, or precast units. Heavy duty handholes shall be either cast-in-place or precast units.
a.Cast-in-Place. The method of forming the handhole and placing the concrete shall be approved by the Engineer. The handhole frame and cover shall be set accurately to the finished elevation so no subsequent adjustment will be necessary. Where a handhole is contiguous to a sidewalk, preformed joint filler of 1/2 in. (13 mm) thickness shall be placed between the handhole and the sidewalk.
b.Composite Concrete. If located in sidewalk or other paved surface, the handhole shall be constructed with a portland cement concrete collar around the perimeter of the handhole. The collar shall be 3 in. (75 mm) wide and the depth shall be equal to the adjacent paved surface. Preformed joint filler of 1/2 in. (13 mm) thickness shall be placed between new concrete and existing concrete.
c.Precast Concrete. Where a handhole is contiguous to a sidewalk, preformed joint filler of 1/2 in. (13 mm) thickness shall be placed between the handhole and the sidewalk.
814.04 Backfilling. Backfill shall be placed and compacted in 6 in. (150 mm)
lifts. Any backfilling necessary under a pavement, paved shoulder, sidewalk, or within 2 ft (600 mm) of the pavement edge shall be made with sand or stone screenings. The backfill shall be compacted according to Article 550.07.
814.05 Cleaning. The handhole shall be thoroughly cleaned of any
accumulation of silt, debris, or foreign matter of any kind.
814.06 Basis of Payment. This work will be paid for at the contract unit price
per each for HANDHOLE, HEAVY-DUTY HANDHOLE, or DOUBLE HANDHOLE, of the material type, when specified. SECTION 815. GULFBOX JUNCTION
815.01 Description. This work shall consist of furnishing and installing a
gulfbox junction.
815.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Coarse Aggregate (Note 1) ................................................................ 1004.01
b.Portland Cement Concrete (Note 2) ....................................................... 1020
c.Gulfbox Junction ................................................................................ 1088.07 Gulfbox Junction Art. 815.04 Note 1. Gradation CA 6 shall be used. Note 2. Class SI concrete shall be used. CONSTRUCTION REQUIREMENTS
815.03 Installation. The location of the gulfbox junction shall be excavated
so that the top of the gulfbox is set flush with the sidewalk or paved surface. When installed in earth shoulder away from the pavement edge, the top surface of the gulfbox shall be 1 in. (25 mm) above the finished grade. The excavation shall be deep enough to accommodate the depth of the box and the base. When the gulfbox is to be constructed over existing conduit, the conduit shall be cut, 90 degree elbows instaIled, and the box constructed as shown on the plans.
a.Cast Iron Gulfbox. The base shall be constructed of 6 in. (150 mm) of concrete placed at the bottom of the excavation. The concrete shall be placed around the conduits and the conduits shall protrude approximately 1/2 in. (13 mm) above the concrete surface. The casting shall be secured by setting the bottom flange into the concrete surface 1/2 to 3/4 in. (13 to 19 mm) while the concrete is still plastic and then trowel the surface smooth. Any piping slots in the sides shall be plugged. The remaining excavation shall be backfilled with suitable material.
b.Composite Concrete Gulfbox. The base shall be constructed of 6 in. (150 mm) of coarse aggregate placed at the bottom of the excavation. The conduits shall protrude approximately 1 in. (25 mm) above the coarse aggregate. The gulfbox shall be set on this base. The remaining excavation shall be backfilled with coarse aggregate. If located in sidewalk or other paved surface, the gulfbox shall be set with a minimum of 3 in. (75 mm) of concrete placed on each side of the gulfbox. Preformed joint filler of 1/2 in. (13 mm) thickness shall be placed between new concrete and existing concrete.
815.04 Basis of Payment. This work will be paid for at the contract unit price
per each for GULFBOX JUNCTION, of the kind of material when specified.
