Building information modelling - Integration of architectural design intentions for creating social values

Scope

This document defines social design intentions for digitalisation and automated BIM-based (Building Information Modelling) analysis. This is distinct and complementary to frameworks that assess specific social values (e.g. privacy, accessibility, spaciousness, etc.), where this document defines social intentions at a more general level. It is also distinct from, but aligned with, processes of documenting, predicting and evaluating a building's performance and adherence to design intentions, which may be done as Post Occupancy Evaluation (POE) or applying space syntax principles.
This document describes a generic data model for representing social design intentions, a process for capturing social design intentions (from elicitation to implementation), the integration of social design intentions into BIM models, and the relationship between social requirements, social intentions, and social values. These concepts apply to both existing buildings and newly constructed buildings.
The target groups of this document are primarily the following stakeholders:
- Architects and Building Designers in their leading of the design process;
- Architectural researchers and Consultants (e.g. anthropologists or sociologists based in architectural studios) in their support of evidence-based design and evaluating social impacts;
- BIM specialists and software developers for developing software that enables interoperability with BIM and supports the integration of social design intentions;
- Public agencies in their preparation of design briefs, managing public design competitions and tenders;
- Social commissioners when they assess social aspects of a building before design handover and after construction.
