WEEK SEVEN: Site visit Site Visit: ! - 2 connecting buildings, 2 basements (2 levels) under both,! - 4 levels in back building, 3 levels in front building! - 26million budget for the build
!
Basement ! - levels: B1 and B2! - Drill piers go down 12 metered ! - Anchored piers into surround properties 15 meter long anchors ! - Slab poured ! - Once ground floor is in it distresses anchors ! - Above slab as are holding priers ! - Can be pulled out if want to ! - Concrete piers drilled with a pilling rig ! - Standing piling rig ! - 12 a day 136 in total ! - Reinforcement made from steel ! - Foundation piles! - Services! - Artificially ventilated ! - Ducks ! - Plumbing services, storm water and servers ! - Storm water extraction system ! - Capping beam ! - Ground level above capping beam ! - Fully reinforced ! - No cold joins as they can let water in ! - Insulation: requirement 25mm fire board ! - Everything under post tension slab has a deflection in it !
basement masonry wall, movement joint is present
Footings for concrete columns Drill piers
!
Tower Crane ! - Sitting on bed rock ! - Mass pads 2.4x1.4 deep ! - Tower crane are 4 piles! - Base of power crane ! - 8 bolts that hold it down !
Steel Stud frames used: Cheaper and quicker to timber
Service ducks in the basement
WEEK SEVEN: Site visit Ground level ! - Existing brick wall had to be braced with steel beams ! - Load bearing walls made from pre cast panels ! - Steel framing: cheaper and quicker to construct ! - Transfer loads from above to these Floors ! - Fire check plaster board installed ! - Column and beam system used for the rooms and building structure, therefore fire rating element ! - this floor is nearly completed compared to the above floors as most of the secondary structure has been built ! - plasterboard as been put up on the walls but not on the roof !
Second floor! - Metal stud work, see a pattern occurring, sae structure as below floor ! - Timber frame (studs and noggins) where vanity will go in order to support the load of a ceramic vanity as metal would not be strong enough ! - Metal stud can be a but flimsy ! - Noggins to go into kitchen joineries as well to support the load of the kitchen services ! - Plaster board acts as bracing for the metal stud, strengthens it ! - Timber studs more labour intensive ! - Metal stud frames already contain service holes and make it easy to infall electricity and plumbing ! - Timber studs braces by cold rolled metal !
!
Existing masonry external wall, had to had steel bracing
Plaster board acts as bracing for the metal stud
Ground floor rooms nearly finished room isolation and fittings need to go in
Mostly steel stud frames used, however some areas contain wooden studs and noggins where heavier elements such as where the bathroom vanity will go
WEEK SEVEN: Site visit Top level ! - Steel frame ! - Columns welded into concrete for extra support! - the Single lift is built from steel beams and pre cast concrete ! - the roof system is slightly tilter in order for the gravity to transfer and catch the water into the box gutter ! - Insulation is being installed in order to trap heat n the building structure ! - box gutter transfer the water down to the basement levels where the water tank is located ! - Only one gutter, all falls down that way ! - mostly bolt joints (pin) !
most of the joints in the building are pin, this on however is a fixed joint and the steel beam has been moulded in the slab
Roof system being installed, it is a tilted roof with a steel frame
!
Flow of information: ! - Data management network like a cloud ! - Revisions plans distribution: multiple disciplines working on this project, need to always keep up to date and send out the revised plan ! - Document control !
!
Materials ! - Concrete: pre cast and in situ ! - steel joins! - Window frames: steel and aluminium ! - insulation: wool ! - plasterboard: waterproofed, fire and regular !
!
Box gutter: this catches all the water and takes it into the basement level where the water tank is this shows how the studs, insulation and plasterboard works together
Plasterboards
WEEK SEVEN:Learning loop  Plastics (Newton, 2014)! - ETFE: light construction lining ! - moulded into different shapes! - source: made from silicon, carbon, hydrogen, nitrogen, oxygen and chloride chemical reactions into monomers, monomers coming each other to form polymers, polymer are long chains of monomers that make the product called plastic! Types and uses: ! - 1. thermoplastics: mouldable when heated and become solid again when cooled, can be recycled, perspex acrylic, polyvinyl chloride (PVC, vinyl), poly carbonate ! - 2. thermosetting plastics: can be shaped and moulded , melamine formaldehyde (laminex) widely used for finishing surfaces, polystyrene mostly used for insulating panels ! - 3. elastomers (synthetic rubber): EPDM, neoprene and silicone !
!
Rubber (Newton, 2014)! - natural: found in nature, source naturally! - synthetic: made at the beginning of the 20th century ! - source: naturally source from rubber tree its slap, can be synthesised in a lab generating a range of variations (plastic)! - properties: resist abrasion, provide good seal, highly feasible, do not shatter to break, highly waterproof, 1.5x density of water, poor conductors, useful insulators, easily recycled, embodied energy varies, cost effective! - natural: seal, gaskets and control joints, flooring, insulation, hosing or piping! - synthetic: EPDM, neoprene and Sicilian ! - considerations: loose properties when exposed to weather ! - protection: avoid sun exposure

Detailing heat and moisture (Ching, 1975; Newton, 2014)! Moisture: ! - strategies to stop water entering a building ! 1. remove openings ! - planned: windows, doors! - unplanned: poor labour, deterioration ! - remove openings: sealants, gaskets ! 2. keep water away from openings ! - sloping roofs with gutters to downpipes or storm water systems ! - overlapping cladding or roofing ! - sloping window sills or wall flashings ! - sloping ground surface away from walls ! 3. neutralise forces that move water through openings ! - forces: gravity, surface tension and capillary action, momentum, air pressure! - PEC: pressure equalisation, capillary break, internal and external flashings ! Heat: ! Heat control! 1. thermal insulation: reduces heat conduction ! 2. thermal breaks: stop materials that conduct heat ! 3. double/triple glazing: multiple layers of glass stops heat ! radiation control: ! 1. light reflective surfaces! 2. shade surfaces! thermal mass: capture heat at day and release at night (stored heat), delay transfer of heat ! Air: ! - similar to water: same 3 conditions, building wrap, weather striping gaps
