- Proactively identify design conflicts, clashes, constructability concerns, incomplete information, and potential field issues, and work with the project team to develop practical solutions before they affect construction.
- Apply sound piping design principles, including equipment accessibility, maintenance requirements, operability, piping routing, support considerations, valve accessibility, tie-ins, installation sequencing, and safe access.
- Work with AutoCAD, Plant 3D, Navisworks, and other project-specific design and coordination platforms. Experience with Inventor, MicroStation, SolidWorks, CADWorx, Revit, and/or Revizto is an asset.
- Be willing and able to learn current design technologies, software, and workflows, including BIM and model based project delivery, as required by the company and its clients.
- Understand how information moves between design platforms and disciplines and adapt software workflows to meet client specific CAD, BIM, modelling, data, and deliverable requirements.
- Work within ONEC’s or client specific CAD/BIM standards, file structures, naming conventions, model-sharing environments, and document control workflows.
- Conduct site visits, equipment walkdowns, field verification, constructability reviews, and interference checks, as required.
- Review existing facilities and field conditions and incorporate accurate field information into brownfield designs and models.
- Establish and maintain CAD standards,



templates, and design workflows to improve consistency, quality, and efficiency.
- Establish and maintain Plant 3D catalogues, piping specifications, project configurations, templates, and associated project database information.
- Perform model coordination and interdisciplinary clash reviews using tools such as Navisworks, Revizto or other appropriate software and take an active role in resolving identified conflicts.
- Communicate and coordinate effectively with engineering disciplines, project managers, clients, vendors, construction personnel, and other project team members.
- Support client communication and provide technical input on mechanical and piping design matters.
- Ask appropriate technical questions, recognize when information is missing or inconsistent, and independently follow issues through to resolution.
- Take ownership of assigned design packages and manage priorities with limited supervision while keeping the project team informed of issues that may affect scope, schedule, cost, or quality.
- Ensure designs comply with applicable codes, standards, client specifications, and project requirements.
- Provide technical guidance and mentorship to junior designers and other project team members.
- Support the development of other designers by sharing design knowledge, software expertise, efficient workflows, and lessons learned.
- Continuously look for opportunities to improve design quality, modelling practices, workflows, templates, and overall project delivery efficiency.

- Working knowledge of applicable Canadian and industry codes and standards relevant to piping and mechanical design, which may include ASME B31.1, ASME B31.3, ASME Section VIII, CSA B51, applicable CSA B149 requirements, API standards, and Alberta regulatory requirements. Experience working on systems governed by CSA B52, CSA B139, and/or CSA Z662 is an asset.
- Solid understanding of construction practices, constructability, equipment access and maintenance requirements, piping installation practices, and multidisciplinary project delivery.
- Experience working on brownfield facilities where existing drawings, models, or facility information may be incomplete or require field verification is considered an asset.
- Excellent communication, organization, and problem-solving skills.
- Ability to work independently, lead design activities, and develop templates and standards for the design team.
- Highly motivated, accountable, and self-directed, with a demonstrated willingness to take initiative rather than wait for detailed instructions.
- A continuous-learning mindset and genuine interest in expanding technical knowledge, software capabilities, and understanding of other engineering disciplines.
- Comfortable learning unfamiliar software and independently developing an understanding of how different platforms can be used together to satisfy project and client workflows.
- Strong attention to detail with the ability to recognize inconsistencies, design risks, clashes, and potential construction issues before they become field problems.
- Able to balance design quality, constructability, project schedule, and budget when developing solutions.
- Experience with BIM, model coordination, common data environments, or other digital project delivery workflows is considered an asset.
- Experience designing plumbing and sewage systems is an asset.
