Design Review (DR) is an independent and / or peer review undertaken by design team, subject matter experts & Client to confirm (a) Design suitability & adequacy against its requirements, (b) Technical & design integrity being maintained and (c) Effectiveness of design processes.
DR is required to ensure that design is safe, achievable, constructible, operable & maintainable. To evaluate if design meets all required technical & project specifications. To identify potential problems associated with design to address issues. To ensure all disciplines are aligned & required interfaces are in place.
After the closeout of DR comments, the refined P&IDs will be used for conducting HAZOP study.
