THE PACIFICA (STRUCTURE)
$42million (Structure only)
Project Completion: October 2020
Structure Completion: May 2020
The Pacifica Apartments complex is one of Auckland’s highest residential building projects. Dominion Constructors were engaged as the structural super-sub for the development.
Once complete, The Pacifica Tower, will be 178m tall, 56-level building with the first 6 levels comprising of a 41-suite boutique hotel and high-end retail on the Commerce Street front & 7 level carpark at the rear serviced by two car lifts; and the tower which is 282 apartments above this.
The build offers residents all facilities including lounges, a lap pool, sauna, steam room, spa, gym, media room, library and barbecue terrace. Dominion have faced many challenges with this project, starting with its central CBD location, a busy shared working environment with minimal space available for storage, loading, lifting and site navigation.
Despite all challenges; for the first time in New Zealand, we operated a full-footprint jumpform, designed and provided by Icon. The jumpform was self-sufficient with a concrete boom pump attached to the jumpform for all concrete placing and a formwork hoist integrated into the screens for the movement of formwork and materials between the floors and welfare facilities.
The tower crane was utilized for the vertical transport of reinforcement for construction of the structure only.
The total jumpform including screens weighed approximately 350 tonnes and climbs using electric screw jacks, with a single floor “jump” taking one hour. The floors are constructed within the perimeter screens which are hung from the jumpform and encapsulate 6 levels. This jumpform screen system offers higher levels of safety and productivity.
The most complex part of the build, which has additional outrigger walls was from levels 23 to 28. We used more than 50% of the concrete required for the project, having poured in excess of 7000m3 of concrete in both vertical and horizontal elements in the first 26 levels.
