Plumbing and Piping Modeler - VDC

Mark III Construction is currently looking for an MEP Modeler to add to our virtual construction team in Sacramento, CA. The MEP Modeler works closely with the Trade Specialists, Foreman, Project Managers and design team during and after the preconstruction phase of Design‑Build, Design Assist or Hard Bid projects. This position’s main responsibility is to create constructible, clash‑free BIM models for MEP systems and to produce detailed fabrication drawings that can be used to pre‑fabricate the off‑site construction of MEP systems.

Mark III is a full‑service construction company comprised of three complementary business units: M3 MEP, M3 Service, and M3 Components. We support projects from initial concept through long‑term maintenance, with specialized expertise in healthcare, higher education, industrial, life science, and technology markets. Our integrated, big‑picture approach allows us to self‑perform electrical, HVAC, plumbing, process piping, prefabrication, and MEP design. By consolidating these services under one organization, clients benefit from reduced profit layers, minimized scope gaps, and simplified project schedules—working with a single, accountable partner rather than multiple consultants and subcontractors.

Headquartered in Sacramento, California, Mark III operates throughout California and Nevada. Our state‑of‑the‑art manufacturing facility serves as a centralized hub supporting five core trades: HVAC, mechanical piping, plumbing, electrical, and metal‑stud framing. To support our continued growth, we will be relocating from our current combined 62,000 square feet of office and operational space to a new 340,000‑square‑foot headquarters at 2031 Optisolar Lane, with the move planned for completion by the end of Q2 2026.
