PRIMARY STRUCTURES

1. FOUNDATIONS - The ERC extensions sits on top of a row of T-Box girders with an in-situ slab of concrete from an existing building.
2. ORIGINAL ERC BUILDING - Southern portion of original structure with the north wall being used as a primary vertical member for canopy. 3. DOUG MCDONELL BUILDING - ERC extension connected to it at basement/ground level.
4. STEEL COLUMNS - Vertical members on Doug McDonell side to support cross beams. 5. CROSS BEAMS - Most crucial horizontal member of the canopy. Forward ones are cantilevered off McDonell side.
- Custom made beams bent at midpoint sit on top of steel columns on McDonell side and attached directly onto original ERC building on the other side. 6. L-BEAM - Joins all cross beams together at midpoint.
SECONDARY STRUCTURES

1. GLASS CANOPY FRAME - Steel frame sits on top of main cross beams to hold glass panels in place 2. ENTRANCE CANOPY - Same as the glass canopy frame but sits on top of cantilevered beams.
3. CURTAIN WALLS - Thin steel frames hold up glass curtain wall on front and and back. - Does not carry roof load.
4. ROOF JOISTS - Sits perpendicular to cross beams and used to support roof cladding and insulation. 5. ROOF SIDE FIXTURE - Hangs off cantilevered beams at entrance
- Frame holds wood cladding fixture and is non load bearing
STRUCTURAL MATERIALS
Above: (Timber Awards 2010)
Rendered reinforced concrete with aggregate wall from Old ERC Building is used as vertical member to hold up southern end of cross beams.
Above: (Timber Awards 2010)
Precast concrete T-box girders sit underneath the main structure and act as the main foundation support.
Main structural elements of canopy (beams, joists, crossbeams, etc) are composed of custom steel beams with anodized finish.
LOAD DISTRIBUTION
2 1 2
1 The beams are spaced evenly from each other and serve an aesthetic purpose internally
1. Steel I-beams distribute load of canopy onto adjacent structures. 2. Existing structures before redevelopment serve as vertical members in load distribution.

1. Cantilevered crossbeam. 2. Crossbeam is cantilevered off Doug McDonell Building. 3. Entrance roof side fixture welded onto cantilevered beam and hangs off there.
1. Crossbeams distribute load of canopy outwards towards the Old ERC Building and midpoint of crossbeam. 2. Load travels downwards towards foundations. 3. At the midpoint, lateral forces are distributed by means of an L-Beam that connects all crossbeams.
