Core Responsibilities

Primary Functions

Safely and proficiently operate a diverse range of heavy construction equipment including excavators, bulldozers, loaders, graders, and compactors to execute tasks such as excavation, trenching, backfilling, and material handling.
Interpret and execute work based on construction blueprints, survey stakes, grade markers, and verbal instructions from supervisors to ensure all operations are performed to the correct elevation, alignment, and specifications.
Conduct thorough pre-operational and post-operational inspections of all assigned equipment, meticulously checking fluid levels, tire pressure, hydraulic systems, and safety devices to ensure machinery is in safe and proper working order.
Perform routine and preventative maintenance on equipment, including lubricating parts, cleaning tracks or tires, and tightening fittings, and promptly report any mechanical issues or necessary repairs to the site foreman or maintenance crew.
Adhere strictly to all company, state, and federal safety regulations (e.g., OSHA standards), including the use of personal protective equipment (PPE) and following site-specific safety plans to maintain a hazard-free work environment.
Maneuver heavy equipment in congested areas with precision and care, constantly monitoring the surrounding environment for other workers, ground personnel, overhead power lines, and underground utilities.
Load and unload construction materials, dirt, gravel, and other aggregates from trucks and stockpiles, ensuring balanced and secure loads for safe transport across the job site.
Execute fine grading and finishing operations with a high degree of accuracy to prepare surfaces for paving, concrete pouring, or landscaping according to project requirements.
Collaborate effectively with ground personnel, such as laborers and pipe layers, using a combination of hand signals and verbal communication to coordinate tasks safely and efficiently.
Maintain a clean and organized work area, both within the equipment cab and around the immediate operational zone, to promote safety and efficiency.
Complete and maintain accurate daily logs and records of equipment usage, hours worked, fuel consumption, and work performed to assist with project tracking and reporting.
Identify and mitigate potential hazards on the job site, proactively communicating any safety concerns or observed risks to the site supervisor immediately.
Utilize GPS, laser guidance, and other modern machine control technologies to enhance accuracy and efficiency during grading, excavation, and site layout tasks.
Assist in the setup and takedown of job sites, including the placement of safety barriers, traffic control signs, and erosion control measures.
Operate equipment to dig trenches and excavations for foundations, pipelines, and utilities, ensuring proper slope, depth, and the use of shoring systems where required.
Monitor the performance and condition of the equipment during operation, listening for unusual noises and watching gauges to detect potential malfunctions before they become serious problems.
Participate actively in daily safety briefings ("toolbox talks") and training sessions to stay current on best practices and site-specific safety protocols.
Guide and assist truck drivers in positioning their vehicles for safe and efficient loading or unloading of materials.
Understand and work with different soil types and conditions, adjusting operating techniques to safely and effectively handle materials like clay, sand, rock, and loam.
Perform site clearing and grubbing operations, including the removal of trees, stumps, and other vegetation to prepare land for construction.
Install and bed utility pipes, storm drains, and other underground infrastructure, ensuring proper alignment and compaction of backfill material around them.
Respond to changing site conditions, such as weather or unexpected ground obstacles, by adapting operational plans in coordination with the site supervisor.

Secondary Functions

Mentor and provide on-the-job guidance to apprentice operators and general laborers.
Contribute to daily and weekly planning meetings by providing insights on equipment capabilities and task sequencing.
Assist with manual labor and other site duties during equipment downtime or as directed by the supervisor.
Participate in the development and review of Job Safety Analyses (JSAs) for specific tasks.
