16. Design and Specification Flashcards
What is the RIBA Plan of Work?
The RIBA Plan of Work organises the process of briefing, designing, constructing and operating projects into 8 stages. It explains the stage outcomes, core tasks and information exchanges required at each stage.
What are the stages of RIBA Plan of Work?
Eight stages from 0-7
0 - Strategic Definition
1- Preparation and Briefing
2- Concept Design
3 - Spatial Coordination
4 - Technical Design
5 - Manufacturing and Construction
6 - Handover
7 - Use
What are the main outcomes of Stage 0 - Strategic Definition?
Outcome: Best means of achieving the client requirements are confirmed.
Core tasks: Preparing client requirements.
Develop business case for feasible options including review of project risks and budget.
What are the main outcomes for Stage 1 - Preparation and Brief?
Outcomes: Project brief approved by the client and confirmed it can be accommodated onsite.
Core tasks: Prepare client brief including project outcomes, sustainability outcomes and spatial requirements. Undertake initial site information (surveys). Undertake feasibility studies.
Statutory processes: Source pre-application planning advise.
Initiate collation of health and safety Pre-construction Information.
What are the main outcomes for Stage 2 - Concept Design?
Outcome: Architectural concept approved by the client and aligned to the project brief.
Core tasks: Prepare architectural concept design aligned to cost plan and project strategies. Undertake design reviews with client and stakeholders.
Statutory processes: Obtain pre-application planning advise & submit outline planning application. Agree route to building regulations compliance.
Ensure: Updated cost plan. Signed off stage report by client.
What are the main outcomes of Stage 3 - Spatial Coordination?
Outcome: Architectural and engineered information spatially coordinated.
Core tasks: Undertake design studies, engineering analysis and cost exercises aligned to updated cost plan and project strategies.
Statutory processes: Review design against building regulations. Prepare and submit planning application.
Ensure: Updated cost plan. Signed off stage report by client.
What are the main outcomes of Stage 4 - Detailed Design?
Outcome: All design information required to manufacturer and construct the project completed.
Core tasks: Develop architectural and engineering technical design. Prepare and coordinate design team building system information.
Statutory processes: Submit building regulations application. Discharge any pre-commencement planning conditions.
What are the key outcomes of Stage 5 - Manufacturer and Construction?
Outcome: Manufacturing and construction completed.
Core tasks: Construct building. Monitor progress against construction programme. Inspect construction quality.
Statutory processes: Carry out Construction Phase Plan. Comply with planning conditions relating to construction.
What are the key outcomes of Stage 6 - Handover?
Outcome: Building handed over, aftercare initiated and building contract concluded.
Core tasks: Hand over building in line with Plan for Use strategy. Undertake review of project performance.
Statutory processes: Comply with planning conditions as required. Building Control sign off.
Ensure: Feedback on project performance.
What are the key outcomes of Stage 7 - Use?
Outcome: Building used, operated and maintained efficiently until end of intended lifespan.
Core tasks: Implement facilities management. Undertake post occupancy evaluation of building performance in use.
Statutory processes: Comply with planning conditions as required.
What are the key parts of Approved Document B relate to designing an office refurbishment?
Travel distances need to be less than 18m in one direction or 45m in more than one direction at 45 degrees.
Up to 60 people is 1 escape.
Up to 600 people is 2 escpaes.
More than 600 people is 3 escapes.
A inner room (room within a room) should have sufficient fire detection, vision panels, no more than 30 people capacity.
All escape routes should have 2m minimum head room. Fire corridors to have 30m fire protection.
Fire escape stairs should be between 1000mm and 1800mm depending on the number of floors and occupants.
What is an inner room?
This is a room by which escape is only possible by passing through another room.
What extra precautions would you take regarding the inner room?
People need to be warned if there is a fire in the outer room. Approved Document B suggests this can be achieved with detection in the outer room with an alarm that can be heard or seen in the inner room or a vision panel between the two rooms.
What are preliminaries?
These are items and costs that are required to complete the project but do not form a specific part of the works.
They provide the description of the project to allow for cost assessment and specify general conditions and requirements for execution. For example: project description, site access and parking.
Examples of preliminary items include: site welfare, scaffolding, provision of temporary services.
What are preambles?
A preamble is an explanation of a document. Commonly found in contracts, specifications and bills of quantities. It helps with the interpretation of a document. It may include:
1) Description of parties to the contract
2) Description of the competence of parties to a contract. This will include a set of general standards for quality of goods or services required.
3) Tendering procedures
4) Objectives of the project
