Building Information Modeler (BIM) 5

About the role

CDM Smith’s Water Services Group is seeking an experienced Building Information Modeler to support site development and water infrastructure projects.

Responsibilities

• Develop and manage Civil 3D models from conceptual and preliminary layouts through fully developed IFC-level models, often using best available or incomplete data.
• Independently establish and refine: horizontal alignments and vertical profiles; sample lines, section views, and cross-section production; complex surfaces using corridors, feature lines, grading objects, and breaklines.
• Perform pressure and gravity pipe modeling for water, wastewater, and storm systems.
• Generate automated plan, profile, and cross-section sheets in accordance with firm and client standards.
• Produce coordinated, construction-ready plan sets throughout all phases of project delivery.
• Perform earthwork determinations and volume analyses using modeled surfaces.
• Develop quantities and calculations derived directly from models, ensuring consistency with project assumptions and design intent.
• Maintain robust data management practices, including file structure, surfaces, references, and model integrity across project lifecycles.
• Apply firm and client standards, workflows, and QC procedures to all modeling and sheet production.
• Cookordination models with engineers, designers, surveyors, and other disciplines to ensure constructability and design intent are preserved.
• Provide technical direction and review as required; while this role may guide others at times, it should not assume the routine availability of junior staff support.

Qualifications

• A high school diploma or equivalent with vocational technical training in basic CADD drafting technology and intelligent modeling.
• 9 years of related experience.
• Domestic and/or international travel may be required.

Preferred Qualifications

• Noteable experience and project examples demonstrating intermediate to expert-level proficiency in Autodesk Civil 3D, including: Alignments, profiles, corridors, grading tools, feature lines, Surface creation and management, Gravity and pressure network modeling, Plan/profile/cross-section sheet automation, Direct experience supporting site development projects with an emphasis on water conveyance systems and buried utility infrastructure.
• Proven ability to work independently with limited oversight; interpret sketch-level information and design intent; and manage multiple active models and deliverables concurrently.
• Experience working on both public and private infrastructure projects within multidisciplinary teams.
• Demonstrated self-starter mentality with strong attention to detail.
• Able to function effectively in a high-demand, deadline-driven environment.
• Strong communication skills and the ability to collaborate across disciplines.
