18
Q

Deep foundations

A

More expensive
Used on high rise
deep piles
drilled piers

19
Q

Deep foundation - drilled piers vs piles

A

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

20
Q

Reinforced concrete

A

rebar used to add strength

21
Q

Prestressed - post tensioned

A

tension elements installed prior to pour

22
Q

Concrete formwork - Materials

A

Wood
Steel
Aluminum
GFRP (Glass fibre reinforced plastic)

23
Q

Joist

A

connects to beams

24
Q

Beam

A

connects to columns

Q

What is a deadload?

A

weight of the slab

27
Q

When coordination with mechanical about concrete slabs, elevated slabs, beam supported floors, what is shown on the structural plan?

A

Slab thickness
Slab bands, beams

28
Q

Slab band

A

It is a wide beam along a column

29
Q

When determining the concrete fire resistance what is it based on?

A

thickness

30
