Papua New Guinea has a significant and growing requirement for new infrastructure, but delivering projects successfully in PNG requires a very different approach to that used in more established construction markets.

Geography, logistics, contractor capacity, imported materials, foreign exchange exposure and regional labour availability can all have a substantial impact on project cost and programme. These factors can also change quickly, meaning that a budget established during early feasibility can become unreliable if it is not based on current market conditions and a realistic delivery strategy.

For governments, developers and investors, the challenge is therefore not simply establishing a project budget. It is understanding how the project can realistically be procured, resourced and delivered within that budget.

Growing Infrastructure Demand in PNG

Papua New Guinea has a significant and growing requirement for infrastructure across the country. Population growth, urbanisation, economic development and the need to improve access to essential services are increasing pressure on existing infrastructure and creating demand for new investment.

This demand spans a number of key sectors, each of which is important to supporting communities, economic activity and future development:

Transport Infrastructure: Roads, bridges, ports and airports are essential for connecting communities, supporting trade and providing access to services across PNG. Given the country’s geography and the limited connectivity between many regions, continued improvement of transport infrastructure is fundamental to social and economic development.

Utilities: Reliable power, clean water and telecommunications are essential to communities and businesses. Existing limitations in these services can restrict development, while improved utility infrastructure can support urban growth, improve living standards and enable wider investment.

Health and Education: Hospitals, healthcare facilities, schools and universities are essential infrastructure for PNG’s growing population. Investment in these facilities is required both to improve access to essential services and to provide the social infrastructure needed to support communities over the longer term.

Resource Sector Infrastructure: PNG has significant potential for further development in mining, energy and other productive sectors. Improved transport, power, water and communications infrastructure can help enable this investment, providing the supporting infrastructure necessary to make future projects more accessible, practical and commercially viable.

Cost Certainty Challenges

Establishing reliable cost certainty for infrastructure projects in PNG can be challenging. Project location, market capacity, availability of labour and materials, import requirements and changing market conditions can all have a significant influence on the final cost of construction. Understanding these factors at an early stage is therefore critical when establishing realistic project budgets.

Market Volatility
Construction costs in PNG can be affected by changes in material prices, labour costs, fuel, freight and foreign exchange rates. Many construction products and specialist systems are sourced internationally, meaning projects can be particularly exposed to movements in overseas markets and exchange rates between the Kina and major trading currencies.

Contractor and Resource Availibility
The number of contractors with the capacity, experience and resources to deliver major or complex infrastructure projects can be limited. Where several significant projects are progressing at the same time, competition for contractors, skilled labour, plant and specialist resources can place additional pressure on both cost and programme.

Limited Historical Cost Data
Historical project data can provide a useful starting point for budgeting, but direct comparisons between projects in PNG need to be treated carefully. Location, access, logistics, specification, procurement strategy and market conditions can vary significantly between projects, meaning historic rates may not always provide an accurate indication of current construction costs.

Importation of Materials
A significant proportion of construction materials, specialist equipment and building systems may need to be imported. Freight costs, shipping times, customs requirements, exchange rates and the availability of international supply chains can therefore have a material impact on project budgets.

The Importance of Realistic and Flexible Cost Planning

 Given the range of factors that can influence construction costs in PNG, early budgets need to be realistic about the level of uncertainty involved. Cost plans should reflect known project risks, current market conditions, logistics and procurement assumptions, rather than relying on a single fixed figure too early in the project.

Key considerations should include:

Appropriate contingencies and risk allowances for areas of uncertainty such as logistics, escalation, foreign exchange and design development.

Scenario testing where alternative procurement, programme or delivery strategies could materially affect project cost.

Regular cost plan updates as the design develops, market information improves and project risks become better understood.

Clear assumptions and exclusions so that clients understand what is included within the budget and where further cost exposure may remain.

This allows cost certainty to improve progressively through the project, while giving clients a more realistic basis for funding, approvals and investment decisions.

Local Engagement and Labour Considerations

Successful delivery in PNG benefits from a combination of strong local knowledge and access to wider technical and commercial expertise. Local understanding is important when assessing labour availability, contractor capability, logistics, community requirements and the practical realities of delivering projects in different parts of the country.

Key considerations include:

Local workforce and contractor capability, including the availability of suitable trades, supervision and specialist skills.

Community and stakeholder engagement, particularly where projects affect local communities or rely on local access and support.

Training and knowledge transfer, where local capability can be strengthened through collaboration with experienced international teams.

Access to specialist expertise, where particular technical, commercial or project delivery skills may need to be supported from outside PNG.

This is one of the reasons we operate with both local and international offices and teams. It allows projects to benefit from people who understand the PNG market and local delivery environment, while also drawing on wider specialist expertise and experience where required.

Resource and Logistics Constraints in Remote Locations

PNG’s geography can make the movement of people, plant and materials a significant consideration for infrastructure projects. Remote locations, limited road access and reliance on sea or air transport can all have a direct impact on both cost and programme.

Key considerations include:

Access to site, particularly where roads are limited, seasonal or unsuitable for heavy construction traffic.

Movement of materials and equipment, including reliance on ports, coastal shipping, air freight or multiple stages of transport.

Availability of plant, labour and specialist resources, which may need to be mobilised over long distances.

Weather and seasonal conditions, which can affect access, productivity and the reliability of supply routes.

These constraints need to be considered early, as logistics and resource planning can materially influence project feasibility, procurement strategy, programme and overall cost.

Regulatory and Compliance Challenges

Infrastructure projects in PNG can involve a range of regulatory, land and approval requirements that need to be understood early. These can affect programme, access to site, design development and ultimately project cost.

Key considerations include:

Planning, environmental and technical approvals, which can influence both design and programme.

Land ownership and access, particularly where customary land or multiple stakeholder interests are involved.

Permits and statutory requirements, including those affecting construction, labour, imported materials and specialist equipment.

Early stakeholder engagement, helping to identify potential approval or access issues before they affect delivery.

Understanding these requirements early allows them to be incorporated into the project programme, risk assessment and cost planning rather than becoming issues later in delivery.

How Quantity Surveyors Add Value

Quantity surveyors play an important role in helping clients understand, manage and control project costs from the earliest stages of development through to completion. In PNG, this requires a clear understanding of both the local market and the wider factors that can influence project delivery.

Key areas where quantity surveyors add value include:

Early feasibility and cost planning, helping clients establish realistic budgets based on scope, location, logistics and current market conditions.

Procurement and tender advice, including consideration of contractor capability, packaging strategy and appropriate routes to market.

Risk and contingency management, identifying areas of uncertainty and ensuring suitable allowances are incorporated into project budgets.

Cost monitoring and change control, providing clear reporting as the design and construction progresses so that decisions can be made before cost issues become significant.

Commercial management, including tender assessment, payment review, variations, claims and final account management.

The real value is not simply in estimating what a project might cost, but in helping clients make informed decisions and maintain commercial control throughout delivery.

Protecting Long-Term Infrastructure Value

Infrastructure investment in PNG should be considered beyond the initial construction cost. Decisions made during planning, design and procurement can have a significant impact on how successfully an asset performs, how easily it can be maintained and the value it provides over its operational life.

Key considerations include:

Whole-life cost, balancing initial capital expenditure against future operating, maintenance and replacement costs.

Durability and resilience, ensuring materials, systems and infrastructure are appropriate for local climate, operating conditions and location.

Maintainability, particularly where access to specialist labour, replacement parts or technical support may be limited.

Appropriate specification, avoiding unnecessary complexity and selecting solutions that are practical to operate and maintain locally.

Protecting the investment, ensuring decisions made during design and construction support the long-term performance and value of the asset.

A strong focus on long-term value helps ensure infrastructure is not only affordable to build, but remains practical, resilient and capable of delivering the intended benefits throughout its life.
