SECTION 02930

DETECTABLE WARNING AT HANDICAP RAMP

SCOPE

A curb ramp shall have a detectable warning. The detectable warning shall extend the full
width of the curb ramp (exclusive of flared sides) and shall extend either the full depth of
the curb ramp or 24 inches (610 mm) deep minimum measured from the back of the curb
on the ramp surface.

MATERIALS AND CONSTRUCTION

chimney seals or liners. Contractor shall perform holiday detection testing in the presence
of an inspector with test equipment appropriate for the product. All detected holidays
shall be marked and repaired by abrading the coating surface with grit disk paper or
another hand-tooling method. After aorading and cleaning, additional coating shall be
hand-aoplied to the repair area as needed. All touch-up/reoair procedures shall be in
accordance with the coating manufacturer's recommendations. All verification and

3.07

Changes in direction of flow or sewer centerline within a manhole shall be made by
forming the flow channel along a smooth curve with as long of a radius as the inside of
the manhole will allow.

Bench shall slope toward invert as shown on the Rehabilitation of Existing Manhole detal|
on Drawing DO2 for proper drainage to the invert channel.

Benches shall be built up to a height as shown on the Rehabilitation of Existing Manhole

detail on Drawing DO2 for the entering and exiting pipes and shall be given a uniform
wood float finish.

3.05

materials handling, mixing, environmental controls, working time, working temperature,
pot life, allowable time between coats (recoat time), safety, and spray equipment. A
permanent identification and date of work performed shall be affixed to the structure in a
readily-visible location, and a final written report shall be provided to Owner and
Engineer detailing the location, date of report, and description of liner installation.

3.03

Active leaks shall be stopped with chemical or hydraulic sealants or cements prior to
installation.

All aveas to be sealed shall be dry, clean, and free of dust, dirt, sand, and othe
contaminants prior to installation. A torch may be required to ensure a dry surface.

Spray System by Warren Environmental, Inc., or Engineer-aoproved equal. Epoxy or
polyurethane coating shall meet the following requirements at aminimum:

1. Shore D Hardness: 85 (per ASTM D2240)
2 Compressive Strength: 12,000 psi (per ASTM D695)

3. Tensile Strength: 6,800 psi (per ASTM D638)

4. Flexural Strength: 11,000 psi (per ASTM D790)

5 Finished Dry Thickness: 125 mils

6. Adhesion to Concrete: Substrate failure (per ASTM D7234)

infiltration of groundwater through the manhole walls and morta’ joints, and to be
structurally caoable of withstanding the pressure of groundwater based on the depth of the
specific manhole being lined.

2. Name(s) of all supervisory personnel that will be directly involved in the Project

3. Proposed product information showing compliance with the specified
requirements listed herein, including chimney seal, grout, and internal liner
material, and the respective manufacturer’ s installation instructions.

4. Documentation of certification of the Contractor, specialty technician, and/or
installer by the product manufacturer and/or its authorized representative
