The Design Quality Indicator (DQI) is a toolkit to measure, evaluate and improve the design quality of buildings.
Development of DQI was started in the United Kingdom by the Construction Industry Council (CIC) in 1999.Page 6, Spencer, N. and Winch, G. (2002). How Buildings add value for clients, London: Thomas Telford. {{ISBN|0-7277-3128-9}} It was initiated in response to the success of Key Performance Indicators devised for assessing construction process issues such as timely completion, financial control and safety on site by the construction industry's Movement for Innovation (M4I). The aim of the DQI systems was to ensure that the M4I's indicators of construction process were balanced by an assessment of the building as a product.Macmillan, S. (2004) Preface to Designing Better Buildings: quality and value in the built environment, London: Spon Press. {{ISBN|0-415-31525-5}} The Science Policy Research Unit at the University of Sussex was commissioned to develop the indicator tool, which was launched as an online resource on 1 October 2003.Construction Industry Council. [http://www.dqi.org.uk/DQI/Common/031001_Launch.pdf DQI Online – How well is your building designed?] 1 October 2003 In 2004 the DQI received recognition from the British Institute of Facilities Management for the role of involving users in the design process.{{cite web|url=http://www.elsalvadorproject.org.uk/maps/downloads/2004/IStructE%20online.pdf|title=DQI online service gets recognition from BIFM – The Structural Engineer|date=2 November 2004|website=elsalvadorproject.org.uk|access-date=8 September 2009|archive-url=https://web.archive.org/web/20111008210600/http://www.elsalvadorproject.org.uk/maps/downloads/2004/IStructE%20online.pdf|archive-date=8 October 2011|url-status=dead}} The DQI tool was made available to users in the United States in 2006, and an online American version was launched on 20 October 2008.
Unlike its forerunner the Housing Quality Indicator (HQI) system devised for the UK's Department for the Environment, Transport and the Regions (DETR) by the consultancy DEGW and published on open access in February 1999,Wheeler, P. (2004) 'Housing quality indicators in practice' in Macmillan, S. (2004) Designing Better Buildings: quality and value in the built environment, London: Spon Press. {{ISBN|0-415-31525-5}} the DQI system instead could be used only by approved facilitators. The criteria and the method of assessment, which though unacknowledged is a simple form of multi-attribute utility analysis, remained inaccessible to design teams and their clients unless they employed a facilitator licensed to use it. Guidance on using the HQI system can be found on the government website.{{cite web|url=https://www.gov.uk/guidance/housing-quality-indicators|title=Housing quality indicators - GOV.UK|website=gov.uk|date=7 March 2023 }} The DQI version for hospitals is also on open access on the national archive.http://webarchive.nationalarchives.gov.uk/20130124042007/http://www.dh.gov.uk/prod_consum_dh/groups/dh_digitalassets/@dh/@en/documents/digitalasset/dh_082085.pdf {{Bare URL PDF|date=March 2022}}
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.Gann et al. (2003), Design Quality Indicator as a tool for thinking: Building Research and Information, London: Spon Press. {{doi|10.1080/0961321032000107564}} 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.
Methodology
DQI is completed by a range of stakeholders in the briefing and design stages of a building project, or on a completed building. Stakeholders who participate include:
- Architects
- Building users (or potential users)
- Building clients
- Facilities managers (or future facilities managers)
- Project managers
- Quantity surveyors (Cost engineer)
- Structural and building services engineers
DQI is applied in a facilitated workshop that is led by a certified DQI facilitator.
