The Owner Project Requirements (OPR) is a document that details the ideas, concepts, and criteria determined by the owner to be important to the success of the project. It typically includes key functional and operational parameters such as occupied hours of a building, use by space type, required temperature settings, and lighting levels. The OPR is used as a guiding document throughout the design and construction process to ensure that the team is aligned with the owner’s vision and goals.

The Owner Project Requirements (OPR) is a critical document that outlines the functional and operational objectives of a project, reflecting the owner's needs and expectations. This document serves as a foundation for the design team to develop the Basis of Design (BOD) and guides the project through its lifecycle, ensuring that the owner's operational needs, such as occupied hours, use by space type, required temperature settings, and lighting levels, are met. The OPR typically includes information on building occupancy schedules, space usage types, environmental conditions like temperature and lighting requirements, and other owner-driven criteria essential for the building's design and operation. By clearly defining these parameters upfront, the OPR ensures that the project team has a clear understanding of what is expected from the building's performance, facilitating a design that aligns with the owner's vision and operational needs.
