1. Sewer and Watermain Mainline Excavator Operator
The mainline excavator operator works with ground personnel to excavate trenches to the proper depth and grade so pipe can be installed at the correct line and grade. The operator must understand proper rigging of pipe, manhole sections, and similar materials, and ensure safe procedures are followed when lowering materials into the excavation.
Main Duties
• Excavate trenches to the proper depth, grade, and side slopes.
• Follow ground-crew directions for bulk excavating, fine grading, hoisting, and gravel placement.
• Cut grade efficiently to allow quick placement of bedding material, minimizing exposure time in wet conditions and keeping production on schedule.
• Ensure all trench work meets OHSA requirements, including trench boxes, slide rails, and shafts.
• Work with the Foreman, site supervisors, and the Health and Safety Department to investigate damage, incidents, and near misses, ensuring procedures follow TACC Construction Ltd.’s Health and Safety Program.
• Review the daily schedule and follow specific excavating instructions.
• Maintain focus on safety, communication, stamina, accuracy, teamwork, and time management.
Qualifications — Must Have
• Thorough knowledge and experience operating a 390 excavator or equivalent.
• Experience in sewer and watermain projects.
• Ability to accurately judge distance and slope.

2. Sewer and Watermain Mobile Crawler Crane Operator
The crane operator safely lifts, moves, positions, and places materials and equipment using specialized machinery. The role includes performing pre-operational inspections, calculating crane capacities, and ensuring compliance with all applicable safety laws and guidelines.
Main Duties
• Operate the crawler crane to precisely lift, move, position, and place equipment and materials in the trench for the sewer and watermain crew, including (but not limited to) sewer and watermain pipe, manhole sections, chambers, stone hoppers, and trench boxes.
• Calculate crane capacities using known weights to prepare for rigging and hoisting.
• Keep an up-to-date crane logbook.
• Review the daily schedule to ensure production targets are met without compromising safety.

• Own vehicle; able to reliably commute to and from various work sites, or relocate before starting work.
• In-depth knowledge and practice of OHSA safety standards and precautions (required for this role).
Assets (Good to Have)
• Experience in sewer and watermain projects.

3. Sewer and Watermain 950 Front Loader Operator
The 950 front loader operator runs a wheel loader in support of the sewer and watermain crew — loading and hauling material, supplying the trench with bedding stone and granular backfill, loading trucks, and keeping the work area organized so that pipe installation production is not compromised.
Main Duties
• Load haul trucks with excavated material (spoil) and clear it from the work area.
• Supply the trench and crew with bedding stone, granular, and backfill material as required to keep pace with pipe installation.
• Place and spread granular backfill into the trench in controlled lifts for the packer operator to compact.
• Stockpile and segregate materials (native soil, granular, topsoil) for reuse and backfill.
• Move pipe, manhole sections, and other materials around the site as directed by the ground crew.
• Assist with rough grading, haul-road maintenance, site access, and general site cleanup.
• Maintain safe distances from the open trench and from workers.
Qualifications — Must Have
• Experience operating a 950-class wheel loader or equivalent.
• Experience on sewer and watermain or underground utility projects.
• Ability to accurately judge loads, distances, and grades.

4. Sewer and Watermain 973 Track Loader Operator
The 973 track loader operator runs a track-type (crawler) loader in the soft, wet, or uneven ground conditions common to open-trench sewer and watermain sites, where track flotation and traction are needed for loading, dozing, backfilling, and moving material.
Main Duties
• Load haul trucks and move excavated spoil in wet or unstable ground where wheeled equipment cannot operate effectively.
• Backfill trenches and place granular material in controlled lifts behind the pipe crew.
• Doze, push up, and stockpile material; rough-grade the work area and maintain site access.
• Move pipe, stone, and equipment around the site as directed by the ground crew.
• Work safely near open excavations, maintaining stable track positioning and safe distances from trench edges and workers.
• Assist with site cleanup, haul-road maintenance, and erosion and sediment control measures.
• Include undercarriage and track checks as part of daily pre-operational inspections.
Qualifications — Must Have
• Experience operating a 973-class track loader or equivalent.
• Experience on sewer and watermain or underground utility projects.
• Ability to judge grade, slope, and ground conditions accurately.

5. Sewer and Watermain Sheepsfoot Packer Operator
The sheepsfoot (padfoot) packer operator compacts trench backfill over installed sewer and watermain, building up backfill in controlled lifts to the specified density to prevent settlement and surface failure, primarily in cohesive soils.
Main Duties
• Compact trench backfill in controlled lifts to the required density and specification, primarily in cohesive (clay) soils.
• Coordinate with the loader operator and crew so each lift is placed and compacted before the next is added.
• Make the required number of passes per lift to meet compaction specifications, avoiding over- or under-compaction.
• Work safely along and over the trench line, maintaining safe distances from workers and the open excavation.
• Assist with rough grading and proof-rolling of subgrade and backfilled areas as directed.
• Monitor compaction quality and report soft spots, voids, or moisture problems to the Foreman.
Qualifications — Must Have
• Experience operating a sheepsfoot/padfoot roller or self-propelled compactor.
• Experience on sewer and watermain backfill and compaction or comparable underground work.
• Working understanding of lift thickness, pass counts, and compaction requirements for granular and cohesive soils.
Assets (Good to Have)
• Familiarity with field density testing and compaction acceptance criteria.

What We Offer
• Competitive compensation at the applicable IUOE Local 793 union rate, commensurate with experience.
• Comprehensive benefits package, including health insurance and an RSP match plan.
