Operational Readiness Activation & Transition (ORAT)

This publication summarises Arup's ORAT methodology, which is modular, flexible, and allows our clients to choose only those services that they don’t wish to fulfil in-house.

Delivering major projects is often achieved under considerable stress, with last minute planning and too much left to chance.

A lack of operational planning and testing can lead to delays—or worse—a premature opening that is riddled by incomplete facilities, system failures, poor customer service and ongoing teething problems.

ORAT is a methodology that provides a framework for managing the risk of opening a new or substantially upgraded, large/complex operation.

Our global Operational Readiness Activation & Transition (ORAT) team work across complex projects to ensure that a new airport, hotel, hospital, stadium or other public asset operates successfully from day one.
