Full Service EPCM

Throughout each gated stage our project manager, project controller, engineers and procurement agents engage our clients in the decision making process to optimize design, reduce rework, and ensure constructability, safety, and reliability.

It is our mission to help our clients make informed decisions resulting in a quality product that we can all be proud of.

Project Management/Controls

Grey Owl Engineering recognizes the importance of project controls and how they form the foundation of a successful project. We set standards for each project according to project size and scope, client requirements and Grey Owl principles.
Our management and execution standards are applied to all projects, big or small. Project controls are adapted to the complexity of the project, assuring a competent and justifiable expense to guarantee the project scope, cost, schedule and quality are managed optimally.
