Architectural Design, Technology and Environment flashcards for ARB Registration (Architects Registration Board)

18 of 50 cards from the Architectural Design, Technology and Environment deck — real questions with worked answers.

1. In RIBA Plan of Work terms, what is the purpose of the 'Brief development' stage and what document captures it?

   Brief development (Stages 1-2) defines the client's requirements, project objectives, spatial needs, budget and constraints. It is captured in the Project Brief, which evolves from the Strategic Brief into a detailed brief informing concept design.

2. List the key elements a thorough site analysis should record before concept generation.

   Topography and contours, orientation/sun path, prevailing wind, access and circulation, services and utilities, existing vegetation and ecology, geology/ground conditions, climate and microclimate, views, noise, neighbouring context, planning constraints, and site history.

3. What is a 'concept' (parti) in architectural design and what role does it play?

   A concept (or parti) is the central organising idea or guiding diagram that drives a design. It distils the brief and site analysis into a clear strategy that informs spatial arrangement, form and material decisions throughout the project.

4. Define 'human scale' in spatial planning and give a typical comfortable circulation corridor width.

   Human scale relates building dimensions to the size, proportions and movement of people so spaces feel comfortable. A typical comfortable single-occupancy corridor is about $1200\,\text{mm}$ wide, with $1800\,\text{mm}$ allowing two wheelchairs to pass.

5. Distinguish horizontal and vertical circulation, giving examples of each.

   Horizontal circulation moves people across a level (corridors, lobbies, streets). Vertical circulation moves people between levels (stairs, lifts, ramps, escalators). Good design coordinates both into legible, accessible routes.

6. What is the difference between 'served' and 'servant' spaces (Louis Kahn's classification)?

   Served spaces are the primary occupied rooms where main activities occur; servant spaces support them (services, stairs, ducts, stores, toilets). Separating them clarifies plan organisation and services routing.

7. Define 'place-making' in the context of design quality.

   Place-making is the design of buildings and spaces to create distinctive, meaningful and well-used environments that respond to local context, character and community needs, fostering identity, activity and a sense of belonging.

8. What does 'context' mean when assessing design quality, and name three contextual factors a scheme should respond to.

   Context is the physical, social, historical and environmental setting of a site. Schemes should respond to factors such as local building materials and vernacular, scale/massing of neighbours, street pattern, views, and cultural/historical significance.

9. State the seven principles of Universal (Inclusive) Design.

   1) Equitable use, 2) Flexibility in use, 3) Simple and intuitive use, 4) Perceptible information, 5) Tolerance for error, 6) Low physical effort, 7) Size and space for approach and use.

10. What is the difference between 'accessible design' and 'inclusive design'?

    Accessible design meets minimum standards (e.g. Part M) so disabled people can use a building. Inclusive design goes further, creating environments usable by the widest range of people regardless of age or ability without special adaptation or segregation.

11. What is the maximum gradient and maximum individual flight length (going) for an accessible ramp under UK Approved Document M?

    An accessible ramp should be no steeper than $1{:}12$ for a flight up to $2\,\text{m}$ long, $1{:}15$ up to $5\,\text{m}$, and $1{:}20$ up to $10\,\text{m}$, with level landings between flights.

12. Define a 'load path' in a structure.

    A load path is the continuous route by which forces (loads) travel through structural elements from their point of application down to the ground/foundations, e.g. slab to beam to column to foundation to soil.

13. Distinguish dead loads, imposed (live) loads and wind loads.

    Dead loads are permanent self-weight of the structure and fixed elements. Imposed/live loads are variable occupancy loads (people, furniture, snow). Wind loads are lateral and uplift pressures from wind acting on the building.

14. Compare a frame structure with a load-bearing wall structure.

    A frame structure (columns and beams) carries loads through a skeleton, allowing open, flexible plans and non-loadbearing infill walls. A load-bearing wall structure carries loads through solid walls, limiting openings and plan flexibility but is simple for low-rise.

15. What is the difference between a beam in bending experiencing tension and compression, and where do they occur in a simply supported beam?

    In a simply supported beam under downward load, the bottom fibres are in tension and the top fibres are in compression, with a neutral axis of zero stress between them.

16. Name three structural systems used to resist lateral (horizontal) loads in buildings.

    Shear walls, braced frames (diagonal bracing), moment-resisting (rigid) frames, and central cores. These transfer wind and seismic forces to the foundations.

17. What are the primary functions a building envelope must perform?

    Weathertightness (keep out rain/water), thermal insulation, airtightness, control of vapour/condensation, structural support of cladding loads, fire resistance, security, acoustic separation, and daylight/ventilation control.

18. Distinguish a 'rainscreen' cladding system from a face-sealed system.

    A rainscreen has an outer screen with a drained and ventilated cavity behind it, so any water passing the screen drains away. A face-sealed system relies solely on the outer surface and joints to keep water out, with no second line of defence.
