Owner’s engineer & design assurance

Independent engineering for the people who carry the risk.

Design assurance roles under National Grid TP141, owner’s engineer support, technical bid writing and the project and procurement management that keeps a scheme on programme.

Contractors and asset owners increasingly need engineers who can hold a design to account without slowing it down. We provide Contractor Design Assurance Engineers under TP141, act as owner’s engineer for developers and utilities, and write the technical responses that win tenders.

The same engineers also take on the unglamorous work that decides whether a project closes out cleanly: requirements management, specification, procurement, factory testing and commissioning documentation.
