Receive patching material shipping documents, certifications, and MSDS for field engineer Select approved material supplier prior to bidding (if applicable), receive price quotes, and arrange delivery schedule and sign contract agreement
Maintain materials storage area Verify compliance of safety and environmental regulations in material staging area
Equipment Assemble required hand tools of correct sizes prior to starting work Inspect equipment for damaged components that can cause disruption to project Verify project has necessary equipment on site prior to starting work, including equipment such as vacuums required for air quality compliance Verify equipment is in compliance with OSHA regulations and state air quality plans
Assemble safety equipment and protective wear for project Inspect testing equipment to insure it is properly working and in good condition Verify fuel supplies are readily available and convenient for equipment (saw, compressor, and so on)
Inventory quantity and condition of traffic control devices to comply with specifications and traffic control plan Maintain sufficient replacement blades for sawing joint face Verify weather radar is available or accessible to monitor potential adverse weather conditions
Check air compressor for air dryer and oil trap and inspect for contaminant-free operation
Preparation Deploy traffic control devices consistent with traffic control plan Inspect traffic control setup Initiate public relations outreach to notify residents of pending work Coordinate scheduling of project to avoid conflicts with major public events or unrelated work
Maintain work zone safety with traffic flagging operation, pilot car, or as otherwise specified Verify traffic flow and pedestrians are away and protected from potential flying debris Delineate areas by marking (painting) pavement repair locations consistent with plans
Deploy protective wear, including respirators for, sawing, and so on Direct necessary preparatory work, such as marking area to be removed, checking equipment and so on Conduct pre-construction meeting with crew to discuss all project elements, including safety and traffic control
Inspect full or partial depth repair procedures and techniques Sequence relocating work zones to coordinate a moving repair operation with planned traffic flow
Monitor equipment operation used to saw area of concrete to be removed
Application Deploy traffic control devices consistent with traffic control plan Direct sawing and drilling operations Check weather forecast and radar to insure suitable condition for joint sealing Troubleshoot potential problems
Maintain work zone safety with traffic flagging operation, pilot car, or as otherwise specified Direct mixing and placement of patching material or pouring of ready mix concrete Sequence relocating work zones to coordinate a moving repair operation with planned traffic flow Review project after completion to insure joint debris or materials are removed from site
Cut and remove deteriorated concrete Make cylinders for material testing Troubleshoot potential problems
Drill holes in sound concrete for dowels for load transfer for all full depth repairs Ensures that finished concrete is properly cured
Mix and place patching material or assist with pouring of ready mix concrete ensuring finished patch is level with adjacent pavement Reseal joint if patch is adjacent to pavement joint
