Looking beyond finance

As global leaders in infrastructure development convene in Singapore this week, they must confront a multi-trillion-dollar gap in investment. New solutions - some already being explored in Singapore - can help overcome this challenge.

Singapore implemented an electronic road pricing system in 1998 and the system, the first of its kind, has been credited with lowering traffic volume and providing a more efficient transportation network.

ACROSS the globe - in developed and developing countries alike - insufficient and outdated infrastructure is eroding the quality of life for individuals and slowing national economic development. Adding to the challenge, trillions of dollars in infrastructure investment are needed annually just to keep pace with expected population growth.

Almost 200 world leaders in infrastructure development and investment are meeting in Singapore this week for the fourth annual Global Infrastructure Initiative (GII), a summit convened by global management consultancy McKinsey & Company. Among the crucial topics on the table is how to narrow the gap between current spending trends for road, bridges, water and power systems, and other essentials of public infrastructure and the projected needs.

A new analysis from the McKinsey Global Institute (MGI), to be released this week in tandem with the summit, estimates that the world must invest US$3.7 trillion a year on infrastructure over the next two decades, primarily for roads and power systems, to keep up with population trends. In total, US$69 trillion of investment will be needed between now and 2035. The majority of the need is in emerging markets, and more than half is in Asia.

However, investment to date is not keeping pace. MGI found that from 2000 to 2015, average investment rates lagged what will be needed going forward in many large economies. Notably, gaps appear most pronounced in Brazil, Indonesia and Mexico, but the developed world (e.g. the United States, United Kingdom and Germany) is also falling short. The gap to 2035 amounts to US$5.5 trillion even before additional costs to meet the Sustainable Development Goals.

Market voices on:

Fortunately many countries understand the challenge and increased their infrastructure spending, in terms of share of GDP, between 2013 and 2015, notably India, Indonesia and South Africa as well as some European countries. At the same time, however, spending has stagnated in the United States. And it has dropped, arguably rightfully so, in China and Australia.

Outdated and insufficient infrastructure can be dangerous as well as simply inconvenient. But beyond these considerations, inadequate infrastructure can be a significant drag on economic growth.

Among other benefits, appropriate infrastructure provides safe and reliable energy, promotes inclusive industrial growth, and eases movement of goods and labour. Every dollar invested in infrastructure can return an additional 20 cents to GDP in the long run, a 20 per cent rate of return.

Without doubt, governments must continue to increase their investment in infrastructure, but spending increases alone will not bridge the projected gap with real needs. Beyond finance, government must take the lead to ensure that infrastructure spending and assets deliver the greatest benefit.

McKinsey has identified three specific areas in which improved infrastructure efficiency and effectiveness can save more than US$1 trillion a year globally. Singapore is already exploring or leading in some of these opportunities and can offer first-hand insights to leaders gathered for the infrastructure summit.

First, governments must strive to squeeze the most use out of existing infrastructure. While new projects often attract attention, improving and prolonging the life of current infrastructure could capture about two-fifths of the estimated savings.

Governments and asset owners can use modern data analytics to prioritise maintenance and repairs, deploy smart systems that augment capacity and reduce demand with targeted pricing mechanisms.

Singapore, for example, implemented an electronic road pricing system in 1998 for traffic in the country's central business district. The system, the first of its kind, is credited with lowering traffic volume and providing a more efficient transportation network. The system is also expected to be expanded to include features like parking payments and real-time traffic information.

Next, public and private sectors must work together to deliver projects more efficiently, beginning with construction. Streamlined delivery accounts for another two-fifths of the estimated savings. MGI found that, globally, annual labour-productivity growth in construction averaged just one per cent over the past two decades, compared with an average of 2.8 per cent for all sectors and 3.6 per cent for manufacturing.

Despite improvements in recent years, construction productivity across Asia continues to lag that in other industries. In Malaysia and Singapore, for example, labour productivity in construction is about a third the average seen across other industries, which costs Singapore about US$15 billion a year in lost value and Malaysia about US$11 billion. The situation is more pressing in Indonesia, where construction productivity is just more than a tenth the overall average, costing the economy about US$190 billion a year in lost value.

By addressing a full menu of initiatives - regulation, design processes, contract structures, procurement and supply-chain management, on-site execution, new technology, materials and automation, and workforce development - construction productivity could be boosted by up to 60 per cent, MGI concludes.

The final fifth in estimated savings comes from improved project selection. Too often, for instance, projects are still approved based on a "wow" factor, political tradeoffs or wildly optimistic use projections. Instead, governments should use fact-based analysis to identify projects that present the strongest objective business cases and to evaluate the realistic costs and benefits of each idea.

As the world struggles to meet the infrastructure needs of a growing population, increased finance is just a part of the solution. Governments and private companies can work harder to extract greater good from current assets and new funding, delivering greater benefits to individuals and companies and creating a smoother path for economic growth.
