Job Description: CAD/BIM Drafter & Modeler

D N B Infrastructure, Inc (formerly R N R Construction, Inc)

About Us

Founded in 2007, we are a fast-paced civil and structural infrastructure design and construction firm specializing in bridge projects, but our expertise extends to all types and sizes of earthwork, steel, and concrete infrastructure work. Our advance digital workflows allow us to provide comprehensive solutions to our clients in both bid-build and design build projects.

Our engineering and drafting team operates under the principle of maintaining a single, reliable “source of truth.” While we leverage multiple Autodesk modeling and drafting platforms, our workflows are centered on creating interconnected, data-rich models grounded in actual structural geometry and standard construction practices. By harnessing the strengths of each software, we integrate all construction disciplines within the Autodesk Revit environment—producing a unified model that enables effective clash detection and interdisciplinary coordination across the entire project scope.

The result of this drafting and modeling philosophy is a powerful digital prototype of the construction—developed well before work begins in the field. This proactive approach has enabled our firm to significantly reduce RFIs (Requests for Information) during construction, thereby promoting a faster, safer, and more streamlined project delivery.

Because our workflows are grounded in real-world construction practices, our output models consistently achieve a Level of Detail (LOD) of 350 or higher. This high level of detail enables us to 3D print precise structural models for both conceptual visualization and construction sequencing. What began with a single Creality Ender 3 has grown into a dedicated 3D printing lab equipped with printers of various types and sizes—allowing us to produce accurate, tangible representations of complex infrastructure designs.

Position Overview

We are seeking motivated and dynamic CAD/BIM Drafters to join our innovative team. The ideal candidates will have experience interpreting civil infrastructure plans, proficiency in Autodesk Civil 3D, and a foundational understanding of 3D modeling software—whether Autodesk Revit, Inventor, or other transferable platforms such as SolidWorks, SketchUp, or Rhino.

We’re looking for individuals who are driven, curious, and eager to push the boundaries of existing modeling workflows. Candidates should thrive in a constantly evolving environment—one where we continuously refine our processes, adopt new technologies, and innovate in the creation of accurate, data-rich 3D models that reflect real-world construction practices.

Key Responsibilities

• Develop detailed 3D models using Civil 3D and Revit software.
• Produce comprehensive engineering design and construction drawing sets, ensuring all documents are design-complete and construction-ready.
• Read, review, and interpret civil & structural plan sets of various complexities, including all disciplines of earthwork, underground, utilities, and structural with a strong attention to integrating all information, and identifying discrepancies or conflicts.
• Communicate effectively with project teams to address plan discrepancies and propose solutions to avoid conflicts.
• Create parametrically correct 3D models for visualization, including using our 3D print lab.
• Collaborate with the visualization lab manager on the development of VR, AR, and the latest Mixed Reality models for enhanced client and project visualization on location.
• Stay current with emerging technologies and contribute to the development of new workflows and practices.

Qualifications

• Very High proficiency in Autodesk Civil 3D and Revit software is required.
• High experience in reading, understanding, and interpreting civil and structural ( in 2D Sic!) drawing sets, especially survey, alignment and elevation data and structural details, experience reading complex infrastructure drawings is required.
• Strong attention to detail and the ability to understand earthwork, structural and civil 2D design drawings, and think and visualize in 3D.
• Excellent English communication skills, particularly in conveying technical information, modeling workflows, and resolving design and construction clashes.
• Proactive, forward-thinking attitude with a willingness to embrace emerging technologies and methodologies unseen in the Infrastructure Markets.

Why Join Us?

At our firm, we deliver drawing and modeling services followed immediately by our own construction of those drawings. This is non-existent in the infrastructure industry. Our in-house modeling and visualization capabilities are becoming iconic, and foundational to delivering projects in a workflow that did not exist a few years ago and does not exist in the marketplace. Join an Infrastructure Design and construction Team that is a decade into some of the most cutting-edge Modeling, 3D Drafting, and 3D printing, disrupting at its core an Infrastructure Design and Construction Industry, dislocating its static in the 2D “Plan”, “Elevation” and “Section” views of the 19th Century.

Compensation ?

This firm offers some of the best compensation and benefits in the engineering and construction industry. Located in Sacramento, CA, a wonderful Northern CA location just a hop away from Tahoe, Napa, the Sierras and the Bay Area, we require the entire team on location every day.

How to Apply

If you are a thinker, proficient at Autodesk, passionate about civil and structural infrastructure design and construction; if you are courageous to work with a team that embraces cutting-edge drafting technology, we encourage you to apply immediately as multiple positions are now open. Please submit your resume and a portfolio of relevant work to [email address].
