Building Information Modeler (BIM) 5

CDM Smith•UNAVAILABLE, UNAVAILABLE

About The Position

CDM Smith’s Water Services Group is seeking an experienced Building Information Modeler to support site development and water infrastructure projects. The role involves independently developing, managing, and delivering Civil 3D models and construction plan sets across multiple disciplines with minimal guidance. The position supports public- and private-sector projects in a fast-paced, delivery-driven environment where initiative and attention to detail are expected. The modeler develops models from conceptual and preliminary layouts through IFC-level deliverables, including alignments, profiles, surfaces, corridors, grading, and pressure and gravity pipe networks. The role also produces coordinated construction-ready plan sets, model-derived quantities and earthwork analyses, and automated plan, profile, and cross-section sheets. It requires robust model and file management, adherence to firm and client standards and QC procedures, and coordination with engineers, designers, surveyors, and other disciplines. Technical direction and review may be provided as needed, but routine junior staff support should not be assumed. Domestic and/or international travel may be required, with travel of 10% or less.

Requirements

High school diploma or equivalent, with vocational technical training in basic CADD drafting technology and intelligent modeling.
Nine years of related experience.
Excellent communication skills and strict attention to detail.
Ability to be a flexible team player and adapt to changing requirements.
Software experience using Microsoft Office for design-related tasks.
Advanced working knowledge of intelligent modeling/CADD drafting commands.
Solid working knowledge of intelligent modeling technologies.
Equivalent additional directly related experience may be considered in lieu of a degree.

Nice To Haves

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, and plan/profile/cross-section sheet automation.
Direct experience supporting site development projects, particularly water conveyance systems and buried utility infrastructure.
Ability to work independently with limited oversight, interpret sketch-level information and design intent, and manage multiple active models and deliverables concurrently.
Experience on public and private infrastructure projects within multidisciplinary teams.
Self-starter mentality and strong attention to detail.
Ability to function effectively in a high-demand, deadline-driven environment.
Strong communication and cross-disciplinary collaboration skills.
Commitment to quality, consistency, and defensible technical work products.

Responsibilities

Develop and manage Civil 3D models from conceptual and preliminary layouts through fully developed IFC-level models, using the best available data, including incomplete data.
Establish and refine horizontal alignments, vertical profiles, sample lines, section views, and cross-sections.
Develop 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 project delivery.
Perform earthwork determinations and volume analyses using modeled surfaces.
Develop quantities and calculations directly from models, maintaining consistency with project assumptions and design intent.
Maintain file structures, surfaces, references, and model integrity throughout project lifecycles.
Apply firm and client standards, workflows, and QC procedures to modeling and sheet production.
Coordinate models with engineers, designers, surveyors, and other disciplines to preserve constructability and design intent.
Provide technical direction and review as required.
