About the Role

Key Responsibilities:

Design Development and 3D Modeling

• Develop and maintain intelligent 3D plant models using AutoCAD Plant 3D for water and wastewater treatment facilities.
• Generate and annotate 2D fabrication, construction, and layout drawings directly from 3D models, including general arrangements, sections, and isometrics.
• Prepare and maintain accurate Piping & Instrumentation Diagrams (P&IDs) reflecting process and control intent.
• Design comprehensive facility and yard piping layouts, ensuring proper routing, connectivity, and maintainability of buried and above-ground systems.
• Produce detailed pipeline profile drawings, including pipe slopes, elevations, fittings, and utility crossings.
• Apply and reference corporate standard details to supplement design layouts, ensuring constructability and consistency across projects.

Piping and Material Coordination

• Design and model piping systems utilizing a variety of materials, including PVC, HDPE, Zeron 100 (Super Duplex), 316 Stainless Steel, Ductile Iron, and CLDI.
• Apply correct ANSI flange ratings, valve types, pressure classes, and fitting standards in all design outputs.
• Ensure compliance with ASME, AWWA, and relevant piping codes and design standards.
• Work closely with mechanical and process engineers to validate piping layouts, hydraulic suitability, and installation feasibility.

Instrumentation and Interdisciplinary Integration

• Integrate instrumentation components—such as flow meters, level sensors, analyzers, and control valves—into 3D models and associated drawings.
• Collaborate with Electrical and Instrumentation Engineers to coordinate control devices, cable routes, and panel interfaces.
• Generate accurate instrument location plans, annotations, and tag lists consistent with P&IDs and project standards.

Drawing Quality, Coordination, and Standards

• Produce high-quality, clearly annotated drawings suitable for fabrication, construction, and field installation.
• Maintain and control drawing revisions, transmittals, and registers per corporate document management procedures.
• Conduct self-checks and participate in design and model reviews for constructability, functionality, and compliance with standards.
• Collaborate with Process, Mechanical, Electrical, and Civil teams to ensure multidisciplinary model integrity.
• Support fabrication shops and field installation teams by providing drawing clarifications, asbuilt updates, and redline modifications.
• Contribute to the continuous improvement of CAD standards, drawing templates, and standard detail libraries.

Qualifications

• Minimum 8+ years of experience in 3D CAD design for water and wastewater treatment plants or similar industrial facilities.
• Advanced proficiency in AutoCAD Plant 3D, including equipment modeling, piping design, and orthographic/isometric generation.
• Demonstrated experience producing yard piping layouts and pipeline profile drawings.
• Strong understanding of piping systems, materials, valves, and instrumentation integration.
• Ability to interpret and prepare P&IDs, general arrangements, and fabrication-level deliverables.
• Proficiency in applying standard detail drawings to improve layout clarity and support field constructability.
• Excellent attention to detail with strong organizational and documentation skills.
• Proven ability to coordinate across disciplines and maintain drawing accuracy under tight schedules.
• Effective communication and teamwork skills in a multi-discipline engineering environment.

Preferred Skills

• Experience with skid-mounted modular systems or prefabricated water treatment packages.
• Familiarity with Navisworks, Revit, or Inventor for 3D coordination and model visualization.
• Exposure to instrument loop drawings, control system integration, and I&E coordination.
• Prior involvement with fabrication, field installation, or construction support activities. xhmxlyz
