Design & Specification Flashcards
What are the stages of the RIBA plan of work?
0 - Strategic definition
1 - Prep and briefing
2 - Concept design
3 - Spatial coordination
4 - Technical design
5 - Manufacturing and construction
6 - Handover
7 - Use
What does RIBA stage “0 - Strategic definition” actually mean?
what are you trying to achieve, what are your requirements?
Is a building even the best way to do it?
What does RIBA stage “1 - Prep and briefing” actually mean?
Meet on and walk around site, throw ideas out, what is possible, how much will anything cost, how long could it take
What does RIBA stage “2 - Concept design” actually mean?
Sketch design, discuss and adjust, think more about time/cost, sustainability, H&S.
What does RIBA stage “3 - Spatial coordination” actually mean?
Planning app + drawings. Drill down to more detail, make sure everything is buildable/functional.
What does RIBA stage “4 - Technical design” actually mean?
echnical drawings and spec, tender project and choose contractor.
What does RIBA stage “5 - Manufacturing and construction” actually mean?
Building actually built, CA role.
What does RIBA stage “6 - Handover” actually mean?
Handover, building is occupied, snagging.
Handover, building is occupied, snagging.
Use. Enjoy building! Maintenance and repair.
What do you understand by the term, modern methods of construction?
Use of off-site factory produced component parts, transported to site and connected together
Whole “modules” built off-site and assembled together
Use of materials other and “brick and block” again to speed up production, ie. timber framing
Use of technology to speed up production, ie. laser cutting of raw materials
When are design risk assessments required?
Whenever there is a designer(s) on a project, comes under CDM.
What technical standards are you aware of and do you use?
Approved Documents
Manufacturer’s instructions and guidance
British Standards documents (“BS”)
Eurocodes (“EN” – “European Norm”, German name “Europäische Norm”)
NHBC if there is a warranty on the building
At what stage would a Building Regulation Application be made?
No plans” application – “Building Notice” given to Local Authority 48 hours before works start.
“Full plans” application – made “well in advance” according to Planning Portal.
Also an “Initial Notice”, whereby Approved Inspector must notify LA at least 5 days prior to works commencing.
Explain the key difference between Prescriptive and Performance specifications.
- Prescriptive: write a detailed description of what you want, including materials, maybe even how it is put together. “Contractor, do what we write/prescribe, and we accept the outcome”. Quite “closed”.
- Performance: write what we want the outcome to be, and leave it up to the contractor to design and specify how it would be achieved. Quite “open”.
What are the 7 stages of RIBA Plan of works?
Stage 0 - Strategic Definition.
Stage 1 - Preperation and Briefing.
Stage 2 - Concept Design.
Stage 3 - Spatial Coordination.
Stage 4 - Technical Design.
Stage 5 - Manufacturing and Construction.
Stage 6 - Handover.
Stage 7 - Use
What is FSC - (Harrier Way)
Forest Stewardship Council - it verifies sustainable sourcing from forest to consumer.
All materials used come from responsibly managed, FSC-certified forests
What is regulation B4 (1)
B4(1) The external walls of the building shall adequately resist the spread of fire over the walls and from one building to another, having regard to the height, use and position of the building.
What is Regulation 7 (2)
Regulation 7(2) would require the same as achieving an A1 rating on the EWS1, in that all combustible materials (primarily timber) would need to be removed from the makeup of the external wall and replaced. Regulation 7(2) is prescriptive and specifies that all materials in the external wall, with very limited exceptions, must be of limited combustibility. This is a fundamental change since the Building Regulations 2000 and 2010 contain functional requirements that the external wall must adequately resist the spread of smoke and fire.
What is included in a tender specification:
- tender invite
- form of tender
- pre-construction information
- preliminiaries
- preambles
- schedule of work
- drawings.
What is the height of a step!
Doc M of the building regulations states that steps must have a height between 150-170mm.
What year was Arden House built and what regs applied at the time?
- It is nine storeys high and has a highest occupied storey more than 18 metres above ground level. It is believed that the Building Regulations 2010
What 3 RICS documents deal with design?
There are 3 key RICS documents you need to be aware of to support your knowledge of design and specification:
2. The RICS Managing the Design Delivery:
3. The RICS Design & Specification Guidance Note:
4. The RICS Building Surveying Pathway Guide:
What was the make up of the replacement wall at Francis Bacon Court with?
REPLACED WITH MARLEY EQUITONE PANELS.
90 minutes intumiscent “siderise” cavity barriers.
Remove temporary breather membrane & replace.
new carrier aluminium rail system. “Nvelope Rainscrean system”
Alideck
branded as B-s1,d0
The Steni Colour panels: The HPL cladding manufacturer
the supporting substructure is concrete slab, timber and cement block
It is used as a open joint rain-screen system which requires horizontal cavity barriers at each floor and around openings. The horizontal cavity barrier in this system should be intumescent to close the cavity only in case of fire. The damage to the installed mineral wool at second level shows that the detail has not been built to the standard required for a rain-screen system. The insulation is missing in most areas. It was observed in front of the floor slab to be Celotex which is not limited combustibility. It is suspected that the main insulation is behind the blockwork and the insulation added in front of the slab is to stop a cold bridging only.
B rated cladding.
Lack of properly installed cavity barriers.
Flammbile insulation
timber in walling.
balconies stacked with timber decking.
What are Marley equitone panels made from for Francis Bacon Court and Arden House?
Fibre cement panels
