The Preconstruction Engineer will support Clark Bros, Inc.’s preconstruction and estimating efforts by developing accurate digital terrain models, performing earthwork quantity takeoffs, and preparing construction models using AGTEK and AutoCAD. This position plays an important role in evaluating project feasibility, developing competitive estimates, identifying potential construction challenges, and supporting project teams through the transition from estimating to construction.

Working closely with the preconstruction, estimating, and operations teams, the Preconstruction Engineer will review civil plans, specifications, existing site conditions, and proposed grading designs to develop reliable quantity calculations and constructible earthwork models. Responsibilities include analyzing cut-and-fill quantities, evaluating site grading and material movement, assisting with quantity reconciliation, and identifying opportunities to improve project efficiency and reduce construction costs.

The ideal candidate has a strong understanding of heavy civil construction, grading and earthwork operations, and digital modeling workflows. This position requires attention to detail, technical problem-solving skills, and the ability to translate design information into practical, cost-effective construction solutions while upholding the company’s mission, values, and commitment to safety.

• Know, understand, and uphold the company’s mission statement and core values.
• Develop and maintain digital terrain models, existing ground surfaces, and proposed grading models using AGTEK and AutoCAD.
• Perform detailed earthwork quantity takeoffs, including cut and fill, over-excavation, unsuitable material, import/export, and other applicable sitework quantities.
• Review civil engineering plans, grading plans, profiles, cross-sections, specifications, and topographic survey data to understand project scope and construction requirements.
• Interpret design surfaces, contours, spot elevations, and site geometry to develop accurate earthwork models and quantity calculations.
• Prepare, analyze, and reconcile earthwork quantities to support cost estimating, bid preparation, and project planning.
• Utilize AGTEK and AutoCAD to develop and refine grading models, surface comparisons, quantity reports, and supporting exhibits for estimating and construction teams.
• Identify discrepancies, design conflicts, missing information, and potential constructability issues during the review of project documents and digital models.
• Assist in evaluating alternative grading concepts, construction approaches, and earthwork strategies to identify cost savings and improve project efficiency.
• Analyze haul distances, material balancing, borrow and waste requirements, and other factors affecting earthwork costs and production.
