Specialized heavy equipment used to bore deep vertical holes into rock or soil for cast-in-place foundation piles, caissons, or deep foundation shafts.

Curb Machine

A specialized slipform paving machine used to extrude continuous concrete curbs, gutters, and highway barriers accurately along grade stakes.

Preventive Maintenance (PM)

Scheduled, routine servicing and inspection—including lubrication, fluid changes, and replacing worn components—performed to prevent unexpected equipment failure.

Predictive Maintenance

Condition-based maintenance that evaluates equipment health in real time using sensor data, such as vibration analysis, infrared thermography, and oil condition monitoring.

Corrective Maintenance

Maintenance tasks involving repair or replacement of broken parts carried out only after equipment has failed or malfunctioned.

Emergency Maintenance

Unscheduled, urgent repairs performed immediately on equipment to address sudden breakdowns that halt critical job site operations.

Rollover Protective Structures (ROPS)

Operator cabin framework, roll bars, and structures designed to protect equipment operators from injury in the event of machine overturns or rollovers.

Computerized Maintenance Management System (CMMS)

A software platform that centralizes maintenance data, automates work orders, tracks spare parts inventories, and monitors equipment upkeep schedules.

Construction Planning

The foundational project management process of deciding what to do, how to do it, when to do it, and who will do it by organizing resources including labor, materials, equipment, money, and time.

Project Scheduling

The process of sequencing, timing, and assigning start and finish dates to project tasks to execute a construction plan efficiently within set budget and quality parameters.

Critical Path

The longest continuous sequence of dependent activities through a project network diagram, determining the shortest allowable completion time for the project.

Float (Slack Time)

The amount of time an activity can be delayed without extending the overall project completion date, calculated as $S = LS - ES$ or $S = LF - EF$.
