markings and raised reflective pavement markers.
783.02 Equipment. Equipment shall be according to the following.
Item Article/Section
a.Grinders (Note 1)
b.Water Blaster with Vacuum Recovery ............................................... 1101.12 Note 1. Grinding equipment shall be approved by the Engineer.. CONSTRUCTION REQUIREMENTS
783.03 Removal of Conflicting Markings. Existing pavement markings that
conflict with revised traffic patterns shall be removed. If darkness or inclement weather prohibits the removal operations, such operations shall be resumed the next morning or when weather permits.

On those improvements where no pavement rehabilitation is required, the pavement shall be repaired with material according to Article 406.05 to the satisfaction of the Engineer. When permanent raised reflective pavement markers are present and conflict with the revised traffic patterns, only the reflectors shall be removed.
783.04 Cleaning. The roadway surface shall be cleaned of debris or any
other deleterious material by the use of compressed air or water blast. Over cleaning to the extent of possible damage to the roadway surface shall be held to a minimum.

follows.
a.Contract Quantities. The requirement for use of contract quantities shall be according to Article 202.07(a).
b.Measured Quantities. The existing pavement marking removal will be measured in square feet (square meters). All existing lines, letters, and symbols will be measured in square feet (square meters).
783.06 Basis of Payment. This work will be paid for at the contract unit price
per each for RAISED REFLECTIVE PAVEMENT MARKER REMOVAL, or per square foot (square meter) for PAVEMENT MARKING REMOVAL – GRINDING and/or PAVEMENT MARKING REMOVAL – WATER BLASTING. Electrical Requirements Art. 801.04

GENERAL ELECTRICAL REQUIREMENTS SECTION 801. ELECTRICAL REQUIREMENTS
801.01 Definition. Codes, standards, and industry specifications cited for
electrical work shall be by definition the latest adopted version thereof, unless indicated otherwise. Materials by definition shall include electrical equipment, fittings, devices, motors, appliances, fixtures, apparatus, all hardware and appurtenances, and the like, used as part of, or in connection with, electrical installation.
801.02 Standards of Installation. Materials shall be installed according to
the manufacturer’s recommendations, the NEC, OSHA, the NESC, and AASHTO. All like materials shall be from the same manufacturer. Listed and labeled materials shall be used whenever possible. The listing shall be according to UL or an approved equivalent.
801.03 Safety and Protection. Safety and protection requirements shall be
as follows.
a.Safety. Electrical systems shall not be left in an exposed or otherwise hazardous condition. All electrical boxes, cabinets, pole handholes, etc. which contain wiring, either energized or nonenergized, shall be closed or shall have covers in place and be locked when possible, during nonworking hours.
b.Protection. Electrical raceway or duct openings shall be capped or otherwise sealed from the entrance of water and dirt. Wiring shall be protected from mechanical injury.
801.04 Equipment Grounding Conductor. All electrical systems, materials,
and appurtenances shall be grounded. Good ground continuity throughout the electrical system shall be ensured, even though every detail of the requirements is not specified or shown. Electrical circuits shall have a continuous insulated equipment grounding conductor. When metallic conduit is used, it shall be bonded to the equipment grounding conductor, but shall not be used as the equipment grounding conductor. Detector loop lead-in circuits, circuits under 50 volts, and runs of fiber optic cable will not require an equipment grounding conductor. Where connections are made to painted surfaces, the paint shall be scraped to fully expose metal at the connection point. After the connection is completed, the paint system shall be repaired to the satisfaction of the Engineer.
