They must be licensed as an S or a J under Oregon Administrative Rule 918-282.
Construction
00960.40Excavation - Remove and replace sidewalks, curbs, paved surfaces, and other materials
as needed. Replace and finish all surfaces to correspond with the existing surfaces. Restore all disturbed landscaping and underground systems to original condition.
Excavate trenches, foundations, and junction boxes to locations, Neat Lines, grades and Cross Sections as shown or as established or approved. Furnish, place, and remove any shoring required to prevent caving of walls.
Dispose of all excavated materials according to 00290.20.
00960.41Horizontal Directional Drilling - Drilling shall not "hump" or deform the Pavement and
shall be guided. Keep drilling pits at least 2 feet from the edge of Pavement. Do not use water to the extent that the Pavement might be undermined or Subgrade softene d. Sand bedding and marking tape are not required with this method.
If jointed conduit is used, verify the joints have not separated by pulling a mandrel through the conduit after installation.
00960.42Conduit :
cylindrical mandrel of the proper size for that conduit and blo w out with compressed air. Mechanical pulling methods may be used for conduit cleaning.
conduit, temporarily remove all existing cable(s) and wire(s). Clean e xisting conduit with cylindrical mandrel of the proper size for that conduit and blow out with compressed air. Mechanical pulling methods may be used for conduit cleaning. Stop W ork and notify the Engineer immediately if there are any difficulties cleani ng the existing conduit. Reinstall existing cable(s) and wire(s) in existing conduit unless otherwise shown. 00960.45 927
00960.43Foundations : Construct foundations for pedestals, posts, and cabin ets according to
Directly against the sides of the excavation in undisturbed or well -compacted material or place in forms. With a continuous pour. To the elevation shown or directed. With conduit ends and anchor rods held securely in proper vertical position, to proper height, using a manufacturer's recommended template until the concrete sets.
Maintain rebar clearances during concrete pour.
Make no adjustments of anchor rods after concrete has set.
Set forms square and true to line and grade. Construct forms of rigid materials that remain in position until removed.
Remove forms and place subsequent loading according to Table 00540-1.
Finish tops of foundations to Roadway, sidewalk or curb grade, or as directed.
Finish exposed concrete foundations to present a smooth, neat appearance. Fill all holes.
00960. 45 Grounding and Bonding :
boxes, metallic junction box covers, and cabinets mechanically and electrically secure to form a continuous, effectively grounded and bonded system.
wire in conduit or as shown. Use an un- insulated No. 4 AWG stranded copper grounding/bonding wire o utside of conduit or as shown.
into the ground with the top of the ground rod 2 inches to 3 inches above the bottom of the junction box to allow for an accessible clamp.
2 inches to 3 inches above the top of the foundation to allow for an accessible clamp.
to the grounding electrode system.
between all poles, pedestals, posts, and cabinets. Bond wires are not required in conduit that only contains circuits that operate at less than 25 volts.
00960.46 928 00960.46 Service Cabinet and Electrical Energy - Install service cabinet and associated Equipment , then arrange for the Utility providing power to have the service cabinet inspected and make the electrical hook -up prior to field testing. Field test according to 00990.70(g) for traffic signals, or according to 00970.70 for illumination.
Bill e lectrical energy costs to the Agency for permanent installations.
Maintenance
00960.60Maintenance, Operation and Power Costs - The Agency will continue normal
maintenance and operations of the existing systems including the furnishing of electrical energy. Do not use for construction purposes electrical energy billed to the Agency or other agencies.
Finishing and Cleaning Up
00960.71As -Built Plans - Upon c ompletion of the installation, submit a red- lined copy of the original
Plans noting all changes made. The information furnished shall include all modifications made and shall represent the material installed and in operation. It shall be sufficiently det ailed to enable maintenance forces to replace or repair any part of the Project under routine or emergency maintenance by direct reference.
