Inadequate OPR documentation can lead to misunderstandings, miscommunication, and misaligned expectations among stakeholders, resulting in project delays, cost overruns, and compromised system performance. Without clear guidance, design teams and contractors may make assumptions that deviate from the owner’s intent, leading to rework, change orders, and potential safety risks. In extreme cases, inadequate OPR documentation can even result in system failures, downtime, and loss of business revenue.
