Minimum Headroom? (stairs)
1950 mm plus the height of one riser (150mm)
number of riser formula
Floor to floor height / height of a riser
Materials used for vertical circulation - stairs
Wood (Prefabricated , Residential)
Steel (Prefabricated, Most common for commercial)
Concrete (Cast on site, Costly, Rarely Used)
Who you must coordinate if you run through an exit stair?
A fire rated bulkhead (lowering available headroom or available width)
Services that serve the exit stair:
Electric wiring that service ONLY the exit stair
Stair pressurization ducts
Elevator Requirements
Not required for buildings less than 3 stories
Types of elevator?
Hydraulic
> operates using pneumatically pumped oil
> intended for low rise (<4-6 stories)
Electric traction
> operates using an electric motor
> better for mid to high rise
Who can pass through elevator machine rooms?
A fire rated bulkhead
Elevator Machine Room Temperature
typ 13 - 32 C
Types of fireplaces
Wood/solid fuel
Gas
Electric
Window frame materials
Wood
Aluminum
Vinyl
Steel
SHGC
Solar Heat Gain Coefficient
> Larger number means more heat gain
Door Coordination
Door grilles are specified by mechanical but coordinated with architectural
Basic Ingredients of concrete
Cement
Water
Aggregate
Fresh concrete properties
Important for foundation
Hardened concrete properties
Important for structure
Additional rebar
used in columns
Shallow foundations
cheaper
less strength
need good soil
Deep foundations
More expensive
Used on high rise
deep piles
drilled piers
Deep foundation - drilled piers vs piles
Piles are better in very wet areas
Pile driving is very loud
Piers require a cure time. Piles can just be tamped into place
Piles cause vibrations during install
Reinforced concrete
rebar used to add strength
Prestressed - post tensioned
tension elements installed prior to pour
Concrete formwork - Materials
Wood
Steel
Aluminum
GFRP (Glass fibre reinforced plastic)
Joist
connects to beams
Beam
connects to columns
