Suggested Answer: C

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.

Wait, are you all sure about that?

No way, it's the Design Narrative for sure.

It's definitely the Basis of Design.

I agree, Basis of Design covers all those parameters.

I thought it was the Owner Project Requirements!

Current Facility Requirements sounds familiar, but I thought that was more about existing conditions rather than operational parameters.

I feel like I've seen a question similar to this before, and it was about the Design Narrative. But now I'm second-guessing myself.

I'm not entirely sure, but I remember something about the Basis of Design being more about the overall concept rather than specific parameters.

I think the answer might be C, Owner Project Requirements, since it usually covers specific needs like temperature and lighting.

This is a good test of our understanding of building design documentation. I think the answer is B - Design Narrative, since that's where the designer would explain the reasoning behind the key design decisions.

I'm a bit confused by the wording of this question. What exactly do they mean by "key functional and operational parameters"? I want to make sure I understand the question fully before answering.

Okay, let me see here. The question is asking about where key functional and operational parameters are specified. I'm leaning towards C - Owner Project Requirements, since that's where the client's requirements would be laid out.

Hmm, I'm not totally sure about this one. I'll have to think it through carefully. Maybe I should review my notes on building design documentation to make sure I understand the differences between the options.

This seems like a straightforward question about building design parameters. I'm pretty confident the answer is A - Basis of Design.

Honestly, this question is a piece of cake. The Owner Project Requirements is the clear winner. Gotta love when they make it this easy.

The Current Facility Requirements? Really? That's for existing buildings, not new designs. Come on, people, let's focus here!

I'm not sure, but I think it could also be C) Owner Project Requirements, as they specify the project goals and requirements.

I agree with Katy, because the Basis of Design outlines the key parameters for the building.

Hmm, this is a tough one. I'm torn between the Basis of Design and the Owner Project Requirements. Guess I'll have to go with my gut and say Option A.

I'm going with the Design Narrative on this one. That's where the design team lays out all the details, including the building's operational requirements.
