Prima Pearl Apartment, n.d., 2014

01_Studio Report Activity OFF CAMPUS Develop an ability ro understand an unfamiliar building site and the different systems used in construction projects of various scales.

PRIMA TOWER UPDATED INFORMATION -Location- Residential skysraper under construction in the Southbank precinct of Melbourne CBD. -Comprise 667 apartments -Budget-$292408906 -72-storey reisdential tower -Full height of 256 meters and stands as the second tallest residential building in Melbourne.

-Now topped out ahead of schedule (with builders Brookfield Multiplex recently completing the final structural concrete pour onsite) -Low-rise portion(10-35) now completed with over 320 apartments settled and the majority of the clients have moved in.

-Work on the level 67 Sky Lounge now underway (major site we have been there during studio) (Prima Peral Construction Update, 2014) Prima Tower under construction Tower crane

Vertical Transport -Jumplifts -Internal Alimak -External Alimak

CRANES -1 core crane- internal climbing crane -1 external crane-Tower crane

(shutters are closed once reinforcing is completed-reuse it when builders are going up)

Internal climbing crane

Slabs construction Process -Formwork -Reinforcing Bars -PT –Post tensioned (slabs) -Pour concrete (every 4 days pouring concrete (for structure to go fast)

Vertical Elements -Precast Panels &columns -Precast Manufacture (Maintain 3 floors of production prior to site installation) -Minimum columns around (for reinforcing)

Initiatives to Accelerate -Removel of precast elements for tower design -Design change to post-tensioned flatslabs (conventiontal reinforced slbas with 200 deep beams)

Pouring concrete

FACADE -Curtain Wall Façade -Cantilevered off slab edge

Procurement -Panels from china manufacture in Shenzheng delivery 16 days

Initiatives to Accelerate -Night shifts for facade installation -Additional crane allocations -Weather Patterns (sequenced with programming installations)

FINISHES Step 1- Curing concrete formwork Step 2- 80-90% done (Toilets, shower, door frame) Step 3- 20% for different clients’ desire to fix or change / Finish painting Floors

Material Selection -Clients’ desire or request -Design & Construct (Buildability, budget, time reduction) -Wall types (precast wall-time consuming X/ stud, clockwok, precast- speed well) -Source of material (local, overseas) -Pre-fabrication off site

IN SITE

Finishes

Level 67 Sky Lounge (underway) -Higher roof top as clients’ change -Panel-7.6 metres high -Apartment has lower height than the sky lounge -Bear Wind load->spand glasses Panels Instore -Clipping in the external of

Steel Poles

the façade -lifted straight up -Sliding table to pull the table out after the panel(9200 panels in sky lounge) is instored -The tower crane is on the top of the sky lounge-> put the panels(heavy dense products) on the wheels to roll up

Metal Roof Decking -corrugated to increase the stiffnes and ability to span across open-web steel joists or more widely spaced steel beams and to serve as a base for thermal insulation and membrane roofing (Ching, 2014, p. 6.14) Rib-spaned Steel Roofing decking

FINISHES -Fire services –(Red poles) are all done with wall bars inside.

-Painting spray with different colours to mark where the walls go -Timber (nobbings) in pieces (footings) -Markers (red) to put the cable through Painting spray -Mechanical system- water pipe /lighting Lighting

Cable Stud

Noggin

MECHANICAL SYSTEM

-Provide the essential service to buildings -the Water supply system provides the water for the residents snitation and consumption.

-The electrical system distributes the electrical wiring can be safe around the under-construction building as shown in the photos where the holes in the wall frame.

Jack Studs

Lobby -the last thing to be filled -High switch sliding doors 45 -NO balcony in the rooms -Windows (only can open up to 45 degress) -Client choice for carpet or timber floor -SHOWER SREEN, TOILETS –FINISHES -Bedrooms – have light coming in -Big Pump in each floor.

-Blue tape (fixing things up/ clients’ request to change or paint) 5-7 ideas to fix (e.g. scratch) ->subjective process

Public Spaces -Pool/Gym Area (overhang gym) ->Tiles/ coulms/Steel screen (designed and builed by the clients) -Timber walls (big budget on it)aesthetical concept -> Manufacuring from Amy Tile

Overhang Gym (Reqire extra support->truss/columns)

Steel screen (designed and builed by the clients)

Dynamic Model -For the process -Foundation Test –>Bay(look like jelly) -Engineers work out how may piles need to use (aprox 200 or more) Temporary Walkpath (Safety)

Greenary wall screen (expensive)

02_Learning Loop Detailing for Heat and Moisture E- Learning, 2014

DETILING FOR MOISTURE

For water to penetrate into a building -An opening -Water present at the opening -A force to move water through the building (Remove any one of the conditions and water will not enter) Solutions -Remove openings -Keep water away from the openings -Neutralisze the force that move water through the openings (Although one is sufficient, two/more strategies are pursued->add security in case one fails.

Openings Planned element (door, windows, skylights. etc) Unplanned openings in the buildings created by (1. Poor construction workmanship 2. Deterionation of materials over a period of time Techniques ot remove opening -Sealant (silicone) Need to be updated/maintained -Gaskets and take care for it

Keeping water away from opening -Grading (sloping) roofs so that the water is collected in gutters which then discharge the water to down pipes and stormwater system -Overlapping cladding and roofing elements (weatherboards & roof tiles) -Sloping window and door sills &roof/wall flashing -Sloping the ground surface away from the walls at the base of the building.

Detailing For Heat Heat GAIN & Heat LOSS occur when -Heat is conducted through the building envelope -The building encelope and building elements are subjetcted to Radiant Heat Souces ( reflective surfaces/ shading systems) -Thermal Mass is used to regulate the flow of heat through the building envelope.

Materials E- Learning, 2014 -Rubber (natural/synthetic rubber)

Neutralising the Forces- ( the most secure strategies for keeping water out of buildings based on neutralising the FORCE which moves water) -Gravity -Surface tension &Capillary action -Momentum -Air pressure differential

Hard, resist abrasion, low fragility, high flexibility/plasticity, waterproof, Useful insulator, durable, high recycle Uses-(Natural: seals, gaskets&control joints, flooring, insulation, hosin&piping) -(Synthetic:EPDM-gaskets, Neoprene-control joints, silicone-seals)

-Plastic Low hardness, low/medium fragility, high ductilitu (heated state), high flexibility, waterproof, poor conductor Types- (Termoplastics/Thermosetting plastics/Elastomers)

-Paint Colour of paint should resist fading (under sunlight), need to resist chipping, cracking and peeling, surface finished can range from matt to gloss Waterbased latex paint flexible> oil based paint Types-(Water based/oil based) WEATHER RELATED DAMAGE OF THEM

Arches, Domes & Shells Ching, 2014 ARCHES (curved structures for spanning and opening support a vertical load primarily by axial compression.

-Masonry arches -Rigid arches VAULTS -Barrel vaults -Groin or cross vaults

Upper-compression Base- tension

DOMES (Spherical surface structure having a circular plan and constructed of stacked blocks) -Scheweler domes/Lattice domes -Geodesic domes

SHELLS (thin, curved plate structure typically constructed of reinforced concrete) -Barrel shells (cylindrical shell structure) Surfaces -Hyerbolic paraboloid -Saddle surface -One-sheet hyperboloid (ruled surface)

-Ruled surface -Rotational surfaces

03_Glossary Appendix 1. Drip- the projection located at the front lower edge of a sill or cornice designed to carry the water away of the wall below.

Shingles

Roofing underlayment and substrate Drip edge

2. Down pipe- the water would run through the DOWN PIPE from the rooftop to the ground level.

Down pipe

3. Vapour barrier- is the material used for damp proofing, typically a plastic or foil sheet which can resists the diffusion of moisture (water) through the wall, ceiling and floor assemblies of buildings.

Vapour barrier

4. Flashing- refer to thin continuous pieces of sheet metal or other impervious material installed to prevent the passage of water into a structure from an angle or joint. Flashing operates on the principle that, for water to penetrate a joint (Ching, 2014, p.7.18).

5. Gutter-a shallow water trough fixed beneath the edge of the roof for carrying the rainwater away. They are typically of vinyl, galvanized steel, or aluminum, although copper, stainless steel, terne metal, and wood ones are also available, aluminum gutters can be cold- formed on-site in continuous runs without joints (Ching, 2014, p.7.18).

Gutters Various Shapes

6. Insulation- the material that can be placed between the interior surface of the building or the exterior surface of the building. It can reduce the of heat loss rate to the environment or heat gain from the environment. Usually used in roofing or ceiling of the top occupied floor in the building. It can also be used in wall system; the insulation can be placed between the exterior and interior walls of the building.

Layers 2’’ Rigid insulation Installed during framing

Insulated exterior wall

Exterior wall sheating

7. Parapet- the low wall or railing along the edge of the balcony or roof. It generally rises above the cornice of a building or form the upper portion of defensive wall.

Top flashing

Parapet wall

8. Sealant-the number of substances used for stopping leaks, waterproofing wood or others.
