    Filter System Upgrade

    ONEC provided preliminary mechanical, instrumentation, and structural engineering for the upgrade of a filter system on a client’s site. The project consisted of preliminary piping design, foundation design, and review of the 3D scan of the area to identify the location of tiepoints. The 3D model was also used for the review of constructability and cost estimating.

    Involvement: Mechanical Engineering, Instrumentation Engineering, and Structural Engineering


    SA2 Sulphur Charge Pumps

    ONEC provided structural, instrumentation, and mechanical engineering services for the upgrade of existing sulphur transfer pumps at a client’s site. The project consisted of new pedestals for the pumps, jacketed and steam traced piping, and tie-ins to existing piping and tank systems.

    InvolvementMechanical Engineering, Instrumentation Engineering, and Structural Engineering

    Design, Build, and Construction Management (DBCM)

    ONEC provided full DBCM services for a $13.2M expansion to a biosolids dewatering, storage, and unloading facility. The project was operational in less than 1 year from project kickoff and met the client’s schedule and budget for much-needed expansion to its ability to handle biosolids from the growing population. The project included new centrifuges, tank modifications, biosolids pumps, silos, buildings, HVAC, and truck loading equipment.

    Involvement: Multidiscipline Construction Management, Safety Management, Electrical and Controls, and Subtrades


    Diesel Power Plant Generator Retrofit

    ONEC provided engineering and construction services to retrofit an existing diesel power plant with a new generator. The power plant required upgrades to its existing structural and mechanical infrastructure, including new supports for the generator.

    Involvement: Mechanical Engineering and Field Fabrication 

    S02 Treatment Design System

    ONEC carried out engineering and design services for the installation of a new process at a recycled petroleum catalyst facility in Fort Saskatchewan, Alberta. The project involved project management services and civil/structural work to provide drawings/designs required to engineer the placement of the storage and reactor tanks, containment systems, and reactor pump skid.

    Involvement: Mechanical Engineering, Project Management, Civil/Structural Engineering



    Disposal Acid Piping

    ONEC was contracted by a client to design, procure, construct, and install the replacement piping for their in situ facility’s acid line. After providing an initial scoping study and design of the piping for the changeover, ONEC procured materials, completed offsite pre-fabrication work, and onsite construction of the piping system. The onsite construction work including testing and restoration of the pipe and installation to prepare for commissioning.
