Constructing Journal Week 5 Week 5 Tutorial NOTE// This is all work we did as a group so is not individual Foundations & Footing: - The Ormond Theology building uses shallow concrete footings, also known as a spread foundation - In some areas of the building, it uses a concrete slab foundation - The footings are classified by its size, allowable load, reinforcement, bearing of footing and is written as (eg. BT1) Primary Structure (Horizontal & Vertical): - Uses steel beams and columns & horizontal & vertical members to carry ap- Structural Fixings I. WELD plied loads to the ground - The steel beams and columns are arranged in a grid frame - The roof beams are cantilevered, only secured by concrete columns on the The use of melting, mixing and breaking can be used as structural fixing but is only restricted to some metals exterior Not appropriate for joining materials with low weldability Secondary Structure (Horizontal & Vertical): - The building uses a cladding grid frame as support for the glass wall at the entrance - Framing is used around windows and doors to increase the combined stiffness of the glass for structural stability - The awnings that overhang from the building are held to the building by braces and clamps.

II. CONCRETE The mixture of cement, aggregates and water. It’s a thick paste that will transform into a stiff structure Poured into ground in order to fix structures III. BOLT They are used in conjunction with a nut attach and fasten two materials together Suitable for two thin materials IV. SCREW An externally threaded and headed fastener that tightens when torque is applied The threads resist movement of the screws and the pull-out force V. NAIL Pin-shaped fastener Is driven into the workpiece by a hammer Holds materials together by friction axially and shear forces laterally

Sustainability/Environmental Analysis/ Economical Implications

-Concrete slabs and columns were in situ which saves energy and cost of transportation of heavy materials -Transportation of materials to site increases both energy and pollution from vehicles (fuel etc) as well as cost -Embodied energy and carbon footprint increases in the construction of the building through machinery use -Concrete walls have different finishes (made to look like timber etc) which requires extra time and expertise, increasing overall cost -Short footings and shallow spread foundations is highly economical -glass panelling of the buildings facing is more expensive than conventional windows -A cantilevered roof requires stronger members/ supports in order to sustain higher loads, need for steel/concrete instead of more conventional timber, increasing cost

Lecture, Readings and Word.

This weeks lecture, readings, and podcasts were all relatively simple in terms of how easy the ideas of materials was able to be understood. I particularly found the podcast about wood and seasoning the wood interesting as it related specifically to my site visit due to the wooden framework of the first story of the house being put up this week. The tutorials were also very helpful because it helped us understand site plans better though they are still very confusing.

A developer is somebody who buys land and builds commercial or residential properties.

Pine Wood Framework

Site Visit 4

This weeks site visit was all about the wooden pine framework that was being constructed on the first floor of the building.

Framework has a bottom and top stop plate, and the wood is pine with a grading of MP 10.

The vertical pieces of wood are called studs and the horizontal pieces are called noggins. The studs are used to keep the building upright, whereas the noggins are used to ensure that the weight of the floor above doesnt cause spreading and bowing. the noggins have to be every 1350mm or less apart to ensure maximum stability.

There are some steel metal braces which hold the walls plumb.

There are larger beams of wood over windows, and the reason for this is that the areas where the windows sit are weaker than the rest of the frame as less wood is holding that particular section up, so in order to strengthen the section a thick piece of wood has to be placed over the section where windows are going to be placed.
