Week 3 - Studio Journal

WEEK 3 - STUDIO JOURNAL New structure uses a mix of wooden framing, concrete slab for foundation as well as concrete blocks for support, seen in the photo to the right.

Plastic sheets are placed around basement of the building for waterproofing and metallic ribbing on each floor serves as reinforcement for slab. The new building has a different structural foundation than the old pavilion. The old pavilion is supported by timber/concrete stumps, meaning the floor level is above ground.

Different grades of gravel have been used to make for different types of concrete. General rule fo thumb is that the bigger aggregate of the gravel, the cheaper the concrete. The very coarse red rocks in the top right photo is used as footing on the ground when it is muddy.

Framing for roof structure

Compression Structure

In order to create the round shape of the structure, large circular plates were used while wooden planks were placed vertically around the outside of the plate.

Construction uses wooden frame beams and columns with a concrete slab as the foundation, as seen in the photo to the left. It retains the old pavilions and links the new structure to the existing building.

It also links to the football oval.

WEEK 3 - STUDIO JOURNAL The Dalton Library links/ connects to an older sandstone building, United Faculty of Theology.

The building uses box gutters placed inside the ceiling of the building as a means to get rid of the rainflow from the roof.

The roof is mainly flat, so a typical eaves gutter cannot work, must have a box gutter to transfer rainwater into the ceiling and out the side of the building, as seen in the photo to the right.

Steel H-columns are used on the inside of the building as the framing of the building. The steel columns take a lots of the dead and live loads that the building has and is subjected to a lot of compression.The outside of the building is covered by non-load bearing glass panels which serves as a means to let the sunshine in. The steel columns and glass panels are seen in the photo above.

Concrete columns hold up the roof on the outside of the building. The concrete columns are made on site, where the cement is transported in. This is cheaper than precast concrete. If the external underside of the roof, the sophet, was taken away, the inside of the roof can be seen as criss-crossed beams supporting the roof, held up by the steel and concrete columns of the building. In the photo above, it can be seen that only that particular side of the roof is cantilevered, where it is supported by the concrete columns.

WEEK 3 - STUDIO JOURNAL The Queens College extension is a structure that extends on the existing Nicholas Laboratories.

The roof is made from a dark steel sheet, as highlighted in the photo below. The roof is slightly slanted as uses eaves gutters to transfer rainwater away. The eaves gutters are attached to downpipes.

The structure connects the ERC to the Doug McDonell building. The roof, as seen above, is supported by steel half eye beams. Spaces between the beams are covered by a timber sophet.

The beams start horizontal and bend to angle upwards and attached to the ERC building, seen in the photo to the left. Because of the bending in the beams, the beams are custom made in a factory and are very expensive.

The concrete flooring have spaces/ joints between them. This is to allow for the natural expansion of the concrete.

The small food booths and pods inside the structure are supported by steel framing with wooden non-load bearing walls. The wooden planks are placed to cover the inside framing.

It can be seen in the photo above that the new structure uses a wooden frame to support itself, and has non-load bearing concrete walls. This method of construction is acceptable on a smaller scale such as this. However, is not sustainable in larger buildings and structures due to the fact that a wooden frame does have the material strength to securely support larger walls of concrete as well as the additional live loads that the structure will be subjected to.

WEEK 3 - STUDIO JOURNAL The MSLE building links the two buildings on either side of it. It is support by steel sheet framing. It essentially uses roof material, steel sheeting, as the wall material for the structure, can be seen in the photo to the left. Because there is no internal framing, the structure uses the buildings on either side to support itself upright. However this presents a potential problem as both buildings are going to move differently. If the structure transmits movement from one building to the other building, the structure may crack and break.

From all the factors above, it can be seen that the structure was a small construction project with a small budget.

The top level from inside the structure is cantilevered using steel beams, as shown in the left photo. The steel beams are attached to the external wall of the building that this structure links to.

The structure uses downpipes to transfer the rainwater picked up on the roof to an external water collection place.

The structure also have air vents to allow for the air from the inside to go out. The vents are angled downwards to prevent particles going inside.
