Level 3 Flashcards
Why were there restrictive spatial parameters (Highgate Wood School, Haringey)?
Following my measured survey, I had to take into consideration the space available and by following guidance such as Technical Annex 2A:Sanitaryware to ensure I met the current guidelines.
What is the guidance you followed for designing the unisex toilet?
School Output Specification Technical Annex 2A: Sanitaryware
Standard toilet cubicles size as per Annex 2A?
At least 1500mm deep x 800mm wide.
What other guidance was available under Technical Annex 2A?
1) Cubicle doors shall be lockable and opened manually from the inside.
2) Cubicle doors shall be of a contrasting colour to pilasters to allow for use by partially sighted pupils in accordance with AD M.
3) In a Secondary School, a floor to ceiling cubicle system shall be used for increased pupil privacy.
4) Toilet cubicle systems shall be constructed from waterproof solid laminate, moisture resistant laminate
What other guidance are you aware of in relation to toilet design?
Approved Document M & BS 8300.
Why did you need a plant/service room?
The existing Biology Preparation did not have enough existing services, a new water heater and booster pump was required and it was not practical to locate this within the Unisex toilet.
Why did the client want clerestory windows?
It was a request from the school business manager as they wanted natural light to enter the toilet.
Why was the sandblasted glass block walling a better solution?
It was cheaper, allowed more light in as it was wider and the lead in time was shorter.
Would could be some drawbacks of installing a clerestory window?
1) Bespoke- so more costly and challenging to replace.
2) Requires more maintenance than glass block.
3) Would need to consider placement such as adjacent to a flat roof (150mm clearance).
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 45º.
- Up to 60 people – 1 escape / Up to 600 people – 2 escapes / More than 600 people – 3 escapes.
- An 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?
Room from which escape is possible only by passing through another room
What do you call a room which can only be accessed from another room? What extra precautions might you take with regard to the inner room
Inner room - People within the room need to be warned if there is a fire in the outer room. Approved Document B suggest that this can be achieved with detection in the outer room with an alarm that can be heard or seen in the inner room, a vision panel or partitions that do not go full height to the underside of the ceiling.
Why did you advise that a consultation with Building Control department?
Inner-inner rooms are not permitted by Building Regulations. Ultimately it was there decision as to whether the inner-inner room proposed would be deemed acceptable.
What is BS 9999?
BS 9999: Code of practice for fire safety in the design, management and use of buildings, provides a best practice framework for fire safety.
Why would you use BS 9999 over Approved Document B?
It is collectively agreed in the fire industry that BS 9999 has advanced a level closer to fire engineered, performance base approach and it has the potential to provide invaluable benefits to the design team.
