Conceptual Framework
DQI applies a structured approach to assess design quality based on the model by the architect Vitruvius, the Roman author of the earliest surviving theoretical treatise on building in Western culture, who described design in terms of utilitas, firmitas and venustas, often translated as commodity, firmness and delight. DQI uses a modern day interpretation of these terms as:
- Functionality (utilitas) – the arrangement, quality and interrelationship of spaces and how the building is designed to be useful to all.
- Build Quality (firmitas) – the engineering performance of the building, which includes structural stability and the integration, safety and robustness of the systems, finishes and fittings.
- Impact (venustas) – the building’s ability to create a sense of place and have a positive effect on the local community and environment.

Famous quotes containing the words conceptual and/or framework:
“Entification begins at arm’s length; the points of condensation in the primordial conceptual scheme are things glimpsed, not glimpses.”
—Willard Van Orman Quine (b. 1908)
“The city is a fact in nature, like a cave, a run of mackerel or an ant-heap. But it is also a conscious work of art, and it holds within its communal framework many simpler and more personal forms of art. Mind takes form in the city; and in turn, urban forms condition mind.”
—Lewis Mumford (1895–1990)
