3 basement car parking levels. 175 columns, 6 pours per level. Columns were delivered pre-slung after the slab pour and immediately set down on the extended deck.
Conventional timeframes on Meriton sites similar to this one typically factor in a concrete pour not less than once every four days —> 18 pours x 4 days = 72 working days @ 5.5 working days/week = 13 calendar weeks.
Using our system First pour occurred 17th October 2018, the last pour occurred 19th Dec 2018 —> 9 calendar weeks. Total time saving: One month.
Value of the construction contract—> 352 units @~$180,000 per unit = $63,360,000 ——> @ 4.5% p.a. average cost of funding = $237,600 of interest saved on the construction funding component alone
Note: The above calculation does not include the savings on the holding cost of the land value. Other cost savings not included are; waste reduction, and the extra safety provisions that would normally be employed if the conventional method was used.
The use of the One Up Columns resulted in fewer people on-site, less loose materials, no open penetrations in the deck and therefore much more straight-forward work health & safety compliance, easier project management due to less trade co-ordination, a cleaner site, and less waste.
