Formwork for the 20-storey National Provident Fund Building constructed in Port Moresby, Papua New Guinea by Japanese contractor, Kumagai Gumi Co Ltd, was supplied by RMD KWIKFORM Australia Pty. The company provided a solution involving its Jump Form System, its Super Slim system and Alform beams to construct the formwork for single-face basement walls, central core walls and columns.

The unobstructed open-floor building features a large concrete central service core and 16 perimeter columns. Main beams were cast in-situ to support pre-cast secondary beams and in-situ cast floors. A car park, extending four levels below ground level, is lined with waterproof concrete perimeter walls.

The site had two tower cranes, primarily for lifting the pre-cast beams, the steel reinforcement and the concrete, so a number of formwork options were considered. The RMD KWIKFORM solution was chosen as being the most cost effective – less than half the figures quoted for competitors' self-climbing systems.
It utilised the company's Jump Form System, which is based around RMD Kwikform's well-established Super Slim soldiers – a readily available range of steel formwork beams and accessories. These were used in conjunction with Alform aluminum beams to form 22 large but lightweight panels for the service core formwork.

The largest of these panels or wallforms measured 7.5 meters by 4.5 meters yet weighed less than 3,000Kg. This allowed the panels to be repositioned quickly and inexpensively, using the tower cranes. Experience showed that the complete service core cycle of strip, lift form, rebar fixing, close up, alignment and concrete pour – approximately 850 square meters – could be achieved in four days.

The Super Slim system and Alform beams were also used for the 3.6 meter high, single faced basement walls – a total of 6,000 square meters of formwork without a single through-form tie. Additionally, the Alform beams were used with yokes to create formwork for the columns.
