Columns. For rectangular sections, minimum to be 1200*300. This is to satisfy FRL180 to retail areas.

Retail (GF) lift and stair cores = min 225mm thick.

Retail (GF) transfer slab = Allow for 350mm thk structural zone.

Lift and stair cores = 200 thk Residential Slabs = Min. 180 thk at wet setdown areas. Elsewhere, maintain 200mm min thick.

7 floor (attic floor plan) = allow for 250mm structural zone Electrical Requirements

Communications riser - Please allow 1200mm w x 600mm D x full height per floor per core (next to each lift) – allow for NBN Communications Room at B1 – Please allow 2100mm w x 2000m D x min 2.2m H at Basement 1 – allow for NBN Electrical riser with meter panel – please allow 1.4m W x 600m D x full height with full front for access to DBs and meter panel per floor per core (next to each lift) Electrical riser (meter panel in main switch room) – please allow 800mm W x 600mm D x full height with full front access to electrical cabling and house DB Main switch Room at basement 1 - 4m x 3m x full height with 2 egress doors – for house and shop meters only, no apartment meter allowed Main switch Room at basement 1 – 6m x 4m x full height with 2 egress doors – for house and shops and apartment meters Kiosk substation at street level is recommended for this site – 4000mm x 3300mm – to be confirmed CCTV cameras recording equipment can be located in security room with monitor. CCTV cameras and DVR can be IP addressable and be monitored remotely if required. Please also refer to Council conditions for CCTV cameras requirements.

Mechanical Retail Kitchen Exhaust - On a tenancy by tenancy basis, assuming full fire separation and system segregation, a 600 x 600 duct will pass 3,000L/s of exhaust air. This will be adequate for an average sized restaurant

Next revision

Car Park Exhaust - The ventilation covering both car park levels will require a single exhaust duct, 1,000 x 1,000. The point of discharge is required to be not less than 6m from any mechanical air intake or point of natural ventilation, not less than 2.5m above ground level. It is preferred that the discharge be at roof level to remove the need for a ventilation pillar at street level. The exhaust fan and attenuators are estimated to be 3600mm long x Ø900mm.

Additional space of 800mm on each side of the fan/attenuator assembly is required for maintenance. Supply air ventilation intake duct is required to be 700 x 700, separate from the exhaust point. The fan assembly will be 2800mm long, x Ø700, plus allowance for maintenance access. Plant room space will be required, subject to further co-ordination with risers, for fan

placement. Current plant room locations do not provide access to an area near lift cores where the duct discharge to roof would normally be located.

4.3

Minor exhaust ventilation ducts are required to be provided to plantrooms used for electrical and fire services and waste storage. Fans for these spaces can be located in the space served.

Allow duct size of 300 x 300 to each space.

4.4

Lift Lobby ventilation (Residential Floors) - Lift lobbies on each level, because there is no means for natural ventilation, will require a central fresh air supply from the roof. Allowance for these ducts is to be 400 x 400 each. Allow for a Ø300 fan for each riser.

4.5

Bathroom Ventilation - Assuming discharge on the façade, allow for a 350 x 350 weatherproof Next revision louvre and Ø300 flexible duct to façade where there are two bathrooms and laundry connected to a single fan.

4.6

Residential Kitchen Exhaust - The kitchens to each residence is located away from the façade and will be equipped with a range hood. The range hoods need to be ducted to building exterior, separate to the wet areas (code compliance). The estimated duct allowance is Ø250mm to a 350 x 350 weatherproof louvre on the façade.

Residential AC - Condensers require direct access to cooling air without recirculation of vented air. The current proposal needs to be modified to prevent recirculation. Condenser space allowance for each apartment is; • 3 bed: 1400h x 900w x 350d, • 2 bed: 1000h x 900w x 350d • 1 bed: 1000h x 900w x 350d It is recommended that additional plant spaces be provided so that each apartment has direct access to its own condenser.

Hydraulic Central gas hot water plant room size 3m X 2,5m ( roof level ) - detail attached Tankpak. Please also consider individual hot water to be in the same enclosure wit AC unit Refer to attached detail- as also the hot water meter will not be required for this option.

Note: As per councils DCP Section E2– OSD is not required due to the site being in an exemption area (Discharges directly into the harbour). However water quality treatment will be required for the site, this will require approx. 15m2 area of surface rain garden pending further analysis in addition to an underground treatment device (GPT or filter).
