underground utilities)
Trades involved in Demolition Phase - ANSWER Demo contractor, Utilities contractor (possibly heavy civil
sub)
Phase 3 of Construction - ANSWER Building Superstructure - Concrete, Steel, Timber
Phase 3 - Building Superstructure - Concrete - ANSWER - More rigid than steel
- Slower to go up than steel
- Need to have 3-4 decks below with scaffolding / reinforcement
- Needs coordination for MEP inserts, embeds and penetrations on its decks
- Pre-Case Concrete can also be used for super-structure construction
Trades involved in Building Superstructure - Concrete - ANSWER Concrete, Plumbing, Electrical,
Mechanical, Elevators, Envelope trade (precast, windows, masonry, etc.)
Phase 3 - Building Superstructure - Steel - ANSWER - Faster than concrete
- Still requires concrete to be poured on decks
- Coordination on steel deck penetrations as vital as in concrete
Trades involved in Building Superstructure - Steel - ANSWER Steel Fabrication, Steel erector, Concrete,
Plumbing, Electrical, Mechanical, Elevators, Envelope trade (precast, windows, masonry, etc.)
Phase 3 - Building Superstructure - Timber - ANSWER - Faster than concrete and steel
- Still may require concrete to be poured on timber decks (not residential)
- Timber needs to be specially treated for fire retardant and humidity properties
