Although the concept of an Owner’s Engineer (OE) has been defined before the turn of the century, it is specifically in the last ten years that the role has been more extensively used for infrastructure and power projects with great benefit to the owners and users of such infrastructure.

The primary function of an Owner’s Engineer (OE) is to provide expert advice and decision support to the client in the successful planning, oversight, execution and implementation of a complex engineering project from inception through to commissioning.

 An Owners Engineer acts as an independent third party to ensure that the technical and build contractors (EPC’s) are adhering sufficiently to the project specification. An OE also fills the gaps in resources and expertise that may exist for a project and hence should have capability across the full spectrum of needs in a project.

TAQA is uniquely positioned to provide OE skills and oversight from inception, feasibility, design and construction through to commissioning and operations. TAQA engineers have successfully acted as the Owner’s Engineer on numerous large-scale projects in the Power, Roads, Rail, Ports, Mining, Metals, Chemicals and Oil and Gas sectors across the globe.

Through our experience we have developed a strong understanding of how to maximise the benefit of the role of Owner’s Engineer for the client.

TAQA Engineering as Owner’s Engineer

TAQA activities as Owner’s Engineer are tailored to the needs of each client and the specific circumstances of the project for which we are appointed. Typically functions undertaken (in addition to what has been described above) by TAQA as Owner’s Engineer include:

  • Site Selection and Review
  • Oversight and Review of Scoping Studies, Prefeasibility Studies and Feasibility Studies
  • Technology Assessment/Selection and Review
  • Licensing support
  • Engineering, Procurement, Construction (EPC) Commercial Technical Specification and Bid assistance
  • Development of Division Of Responsibilities (DOR) for all parties
  • Contract negotiations support
  • Development of an overall project execution plan
  • Develop an integrated master project schedule
  • Identify and quantify project risks and develop a risk mitigation plan
  • Develop design for site specific activities and Owner’s assigned activities
  • Develop & update project cost estimates
  • Regulatory Environment Review and Support
  • Review EPC contractor’s procedures and related documents
  • Perform audits on behalf of the Owner
  • Represent Owner in EPC contractor’s procurement activities
  • Perform design reviews on behalf of the Owner of vendor documents (e.g. drawings, calculations, specifications, constructor/vendor document submittals, etc.)
  • Support Owner with reviewing EPC contractor costs, schedule, and progress
  • Support the owner with plant testing and start-up
  • Provide construction support including oversight of engineering, licensing, procurement and commissioning.
  • Support for design activities/interface with operating units
  • Independent engineering evaluation
  • Training support
  • Miscellaneous support (Deployment, etc.)

Benefits of an Owner’s Engineer

  • An Owner’s engineer can reduce a project’s overall cost by as much as 20% (capital, operation and maintenance) through dedicated oversight and expert knowledge.
  • An Owner’s engineer reduces the overall project risk for the owner.
  • An Owner’s engineer ensures deliverables are in-line with owner’s expectations.
  • An owner’s Engineer effects savings through control of project schedule, defined scope and management, overall project controls and expert technical knowledge.
  • An Owner’s Engineer ensures design optimization that reduces the owner’s lifecycle costs.
  • An Owner’s engineer, brought in when the project is still in the conceptual stage, can help with defining the project size, location, technology selection, configuration, scope, interfaces, and schedule.
  • An Owner’s engineer, involved from project inception can help develop a project execution plan and contracting strategy. The Owner benefits from having a dedicated engineering advisor who is familiar with all aspects of the project and will help the owner identify opportunities that may otherwise be overlooked while avoiding or minimizing risks.
  • Some of the most critical tasks for the role of OE include:
  • Defining and/or reviewing the project scope.
  • Developing a detailed Division of Responsibilities (DOR).
  • Developing, reviewing and refining project design criteria.
  • Assessing and evaluating budgets.
  • Manage feasibility and site selection studies and provide alternatives analysis when required.
  • Analyzing available technologies and their suitability to the project and owner’s goals.
  • Preparing integrated project schedules.
  • Preparing technical commercial specifications.
  • Support with the licensing process, permitting and environmental processes
  • Support with EPC contract documents, including RFP (request for proposal) and evaluations.
  • Provide detailed design, overall project management, contract administration, and construction oversight.
  • Preparation and/or review of equipment procurement specifications and ensure suppliers are in compliance with all contractual requirements.
  • Support development of configuration management control that captures the plant design basis.
  • Support owner’s process management, implementation of earned value, project cost reporting and trending.
  • Development of training programs and capacity building
  • Support the plant commissioning process (system turnover, start-up tests, performance testing, etc.).
