Week 10 Journal

Oval Pavilion Site Visit

The construction workers were working on the concrete seating facing the oval. The concrete seats were angled using formwork built with timber. The concrete seats had a rebate which was used for a flush finish to the timber, whilst the top of the bench had timber nailed to the concrete to lift the timber slats off the concrete. Similarly to the concrete bench, a concrete wall had been constructed using plywood and Oregon timber. The Oregon timber created an imprint on the wall.

The wall to the left has the Oregon timber grain imprint.

The yellow caps at the front are all covering reinforcing bars which will be used when concrete is poured to create another bench.

The tradesmen are attaching timber to the concrete, which will be used to support the timber slats that will be used for seating.

At the back of this picture is the social room. It is a steel frame structure with four wooden columns at the front. The wooden columns are attached to the steel frame with a plate inserted into the timber and then fixed with a 55mm drive pin. The timber columns are used primarily for aesthetics. Steel Purlins are running between the steel beams, however between the purlins and the roof battens, there is 25mm timber before the insulation, this is because of the high amounts of moisture. The columns are LVL (Laminated Veneer Lumbar) because it the glue makes it stronger than normal timber and it is also cheaper.

This is the two way gas fire place on the Eastern wall. The structure is cladded with tunnel groove timber. The tunnel groove timber allows for a cleaner finish as the boards can fix to each other below the surface. At the bottom of the structure (behind the scissor lift) is the fire place, this is an architectural design that makes use of materials allowing people to utilise the fire both inside and outside. The timber frames to the right of the fire place are going to be cladded with cement sheeting. Under flashing is being installed at the top of the timber cladding which a box gutter is attached. Over flashing is then fixed to the box gutter.

Here is Henry demonstrating the tunnel groove timber. The timbers slide into one another as the groove on one timber accommodates a tab on the adjacent timber.

The timber frame work incorporates steel top hat battens. The top hat battens differ from solid battens as they provide greater sound and heat insulation.

The timber frames are attached to the foundation, which is a 230mm thick slab. The bottom plate is fixed to the slab with carbon fibre nails that are able to grasp the slab without any splitting or weakness.
