Hi All What's a conservative cost estimate for basement carparking for a development. So far I have got figures of $1000/sqm to $2000/sqm. assuming about 700sqm of parking. What are peoples thoughts? Thanks
Construction cost is dependent on the State but in Sydney (where construction is expensive) you are looking at least $3k per sqm and more if you include lifts, etc. $1k does seem extremely cheap even for Perth. Also ask if people are including GST in their quotes as this tends to sting a lot of people.
It depends on a lot of factors but as a general rule, I'd say around $2000-2,500/m2. Coastal - limestone, cap rock? Near river - water table, clay (drainage?) Water table in general - dewatering required? (an extreme example is Finbar's Civic Heart in South Perth)
Hi Travis. Sandy soil, not using transfer slab, setback from boundary, using dincell or similar etc about $1200+ GST per sqm. Introduce a transfer slab, sheet piling / grout injection / BA20s, cavity fill brickwork etc and it gets north of $2000/sqm pretty quick.
thanks Aaron for the input. I did manage to find a copy of Rawlinsons 2018 as well, which had a range of $1,855 to $2,000/sqm. Add a bit more for today's prices.
That would likely be for cavity brick retaining off boundary with a transfer slab.....? Best way to avoid the transfer slab is to get your apartment modules lining up with your carbay piers. Slab goes from 686mm to 343/429mm in the blink of an eye.
