Full-time
On-site
Job Description
The Earthworks Engineer specializes in soil mechanics, site grading, excavation, and complex ground stabilization operations.
The incumbent takes direct technical ownership of challenging terrain projects, focusing heavily on executing efficient de-watering systems and land reclamation strategies to transform waterlogged or swampy areas into stable, buildable construction sites.
Responsibilities
De-Watering Operations & Water Management:
Design, plan, and supervise comprehensive de-watering systems (wellpoints, deep wells, sump pumping, and cofferdams) for waterlogged and high-water-table sites.
Monitor ground-water movement, control discharge safely, and ensure continuous site dryness to prevent structural settling or soil liquefaction during excavation.
Select, deploy, and maintain appropriate pumping machinery, piping networks, and filtration units to match site-specific hydrological conditions.
Land Reclamation & Site Stabilization:
Spearhead land reclamation initiatives by evaluating soil composition, managing dredging output, and overseeing sand-filling operations.
Implement ground improvement techniques such as surcharging, vibro-compaction, geo-textile installation, and stone columns to stabilize weak swamp foundations.
Supervise heavy earth-moving machinery (excavators, bulldozers, wheel loaders, and compactors) to achieve proper grading, compaction densities, and elevation profiles.
Geotechnical & Surveying Analysis:
Review soil test reports, geological surveys, and topographical data to formulate safe and cost-effective earthworks execution methodologies.
Collaborate closely with surveyors to monitor settlement markers, slope stability, and excavation depth tolerances.
HSE & Quality Assurance Compliance:
Enforce stringent Health, Safety, and Environment (HSE) protocols around excavation pits, water bodies, and heavy machinery operation zones.
Ensure full compliance with environmental protection regulations, erosion control standards, and statutory civil engineering codes.
Cross-Functional Collaboration & Reporting:
Coordinate daily with site supervisors, project managers, and the General Manager (Technical) during toolbox briefings to align field targets.
Maintain accurate logs of earthwork volumes, fuel consumption, equipment deployment, and daily site progress reports.
Requirements
Bachelor's Degree in Civil Engineering. Professional registration (e.g., COREN) is an added advantage.
Minimum of 10 years of dedicated civil engineering experience, with a proven, verifiable track record in handling de-watering projects and land reclamation in challenging swampy or waterlogged terrains.
Deep expertise in hydrogeology, soil mechanics, and pump system engineering.
Proficiency in civil engineering design software and earthwork volume calculation tools.
Strong operational leadership, problem-solving skills under adverse weather/site conditions, and attention to safety detail.
