Ark Pacific (Ark) offers two proven building solutions designed to meet the demands of PNG’s mining and oil and gas sectors: Its established Flat Pack system and its modular Ready Box system. Both deliver high-quality, fit-for-purpose facilities, but each offers distinct advantages depending on a project’s requirements.
With more than 15 years of experience supplying prefabricated facilities to PNG’s resource sector, Ark has developed its products to address the practical challenges of building in remote locations and demanding operating environments.
Two Systems, Different Advantages
Ark’s Flat Pack buildings have become a familiar choice across PNG’s resource sector. Manufactured using 0.6 mm BlueScope steel insulated wall panels, the system is engineered to Australian standards and certified for use in earthquake zones. Its structural strength, quality and efficient transport footprint make it a practical solution for a wide range of accommodation, office and operational facilities.
Ready Box takes prefabrication a step further. Constructed using robust 3 mm plate steel, its buildings provide an even stronger solution for projects where environmental exposure and durability are particularly important.
The distinction is not about one of Ark’s building systems being good quality and the other being better quality. Ark’s General Manager, Cass Ruka, explains that “both are designed to deliver reliable, high-quality facilities. However, Ready Box offers additional strength and a greater level of off-site completion for projects where these features provide a clear advantage.”
That higher level of prefabrication also delivers a significant practical benefit: Ready Box buildings can be fully functional approximately 70 per cent faster to commission for use after arriving on site. With the building work completed before delivery, installation is primarily a matter of positioning the units, connecting services and commissioning the facilities.
Ready Box in Action: Enga and Lihir
Ark’s mid-2026 supply of a 170-person turnkey construction camp for Santos’ Agogo Production Facility Tie-In Project in Enga Province demonstrates the Ready Box system’s capabilities. The camp comprises 73 modular units covering a range of accommodation and support requirements, including offices, ablutions, medical facilities, kitchen and dining facilities, laundry and recreation areas.
Having arrived on site ready for installation, the buildings reduced the amount of construction work required in a remote location where additional labour, equipment and site activities would have added complexity, time and cost.
Ready Box is also the building solution chosen by Wagstaff Piling for ablution blocks, office buildings and crib facilities they require for the sea wall construction project they are about to undertake on Lihir Island for Newmont.
The selection reflects the particularly corrosive conditions of the project site on Lihir, where sulphur emissions from wellheads and salt spray from the ocean present significant challenges for building materials. In this environment, the additional robustness of Ready Box’s 3 mm plate steel makes it a suitable choice for the project’s requirements.
Experience Matters
The building system is only one consideration when selecting a supplier for a complex resource sector project.
Ark first entered the PNG resource sector market in 2010 with the delivery of a 1,000-person, multi-storey accommodation complex and support buildings for the Exxon Mobil LNG camp. It has delivered a variety of buildings on Lihir since 2017 and continues to supply facilities to other major resource-sector operators in PNG, including New Porgera Limited and K92.
Ruka says the growth of Ark’s business in PNG over a 15-year period, as well as the repeat purchase behaviour of its resource sector clients, is testimony of the superior quality of Ark’s products over others in the prefabricated market. “Our success is also indicative of the value clients place on our construction experience here in PNG, as well the relationships we build with them, and our understanding of local site conditions.”
Cost Effective
Ark’s two building systems give resource-sector developers the flexibility to select a solution that best suits their operational needs, environmental conditions and budgets.
Although Ready Box has a higher upfront manufacturing cost than Ark’s Flat Pack alternative, its overall cost advantage becomes clearer when the entire project lifecycle is considered.
Traditional on-site construction activities associated with assembling and completing buildings can require additional labour, equipment, supervision and time. In remote locations, these requirements can be particularly expensive and difficult to coordinate.
Because Ready Box buildings arrive complete and can be made operational much sooner, they reduce the amount of work required on site and allow facilities to be brought into service faster. When these savings are considered alongside the reduced time needed to establish operational facilities, the overall project cost can be lower than Flat Pack buildings despite the higher initial building price.
