Intelligent Modeling Lead (CADD/BIM) – Transit Projects

CDM Smith; Nashua (NH); On-site; USD 46,000 - 76,000; Full time

Job summary

CDM Smith seeks an Intelligent Modeling Coordinator to lead cross-discipline modeling for transit and multimodal projects. You will coordinate federated models across architecture, vertical structures, transportation structures, roadway design, and MEP, run clash detection in Navisworks, and ensure CADD/BIM standards are followed.

Ideal candidates bring extensive experience with Autodesk tools (Civil 3D, AutoCAD, Revit, Navisworks) and Bentley OpenRoads/OpenRoads Designer, plus mentoring staff

Qualifications

• High School diploma or equivalent with vocational technical training in basic CADD drafting technology and intelligent modeling.
• 12 years of related experience.
• Equivalent additional directly related experience will be considered in lieu of a degree.

Responsibilities

• Cross-discipline coordination — Serves as the firm's go-to Intelligent Modeling Coordinator for transit and multimodal projects, coordinating deliverables across architecture, vertical structures, transportation structures, roadway design, and MEP into a single federated, clash-checked model throughout the project lifecycle.
• Model coordination & clash detection — Runs clash detection in Navisworks and leads resolution across disciplines, catching conflicts early rather than in late-stage design or construction.
• Standards & governance — Establishes, documents, and enforces CADD/BIM standards, templates, and workflows across offices, built on the Autodesk stack and compliant with governing transit agency and DOT design criteria.
• Mentorship & guidance — Provides lower-level modeling personnel with design sketches for preparation of finished design drawings and general layouts, and guidance in refining technical requirements; mentors and trains production staff across offices to build a repeatable, institutional capability.
• Acts as Intelligent Modeling Coordinator for basic to highly complex projects during the project lifecycle to ensure coordination between the design team.
• Performs crosscheck of drawings to ensure consistency of drawings, cross sections, section placement, and layering guidelines, and adherence to the firm's Q/QC standards.
• Performs CADD/technical support tasks such as verifying intelligent model integrity, managing model health and versioning, and maintaining interoperability across the Autodesk toolset (and Bentley where projects require it).
• Reviews manufacturers' or fabricators' prints for aid in design documents.
• Determines material needs and performs necessary calculations using accepted formulas and references per the firm's standards.
• Establishes design criteria for assigned phases of a project requiring the application of engineering principles, material properties, and familiarity with construction, installation, and maintenance procedures.
• Provides general conceptual input to projects during the planning stages and supports or leads field assignments as required.
• Develops BIM Execution Plans, contributes to model-based deliverable scoping, and advises pursuit teams on integration approach, LOD, and production level of effort (LOE).
• Interfaces with clients, agencies, and subconsultants on model deliverable requirements, coordination expectations, and data handoff standards.
• Performs related fundamental engineering support tasks such as plotting drawings, preparing transmittals and overnight packages, file management, filing and distributing prints, assisting in simple design calculations, and coordinating specifications with drawings.
• Performs other duties as required.
