The expanded Top 225 list firms had a combined revenue of $70.85 billion $70.57* 2014 For large international design firms, the past year has been one of uncertainty. Lower oil prices, regional tensions in the Middle East and economic turbulence in Europe have undermined growing demands for infrastructure around the world. And the sharp drop in the Chinese stock market and the Greek debt crisis have given designers two more things to think about. The impact of the uncertainty in the world market can be seen in the results of ENR s Top 225 International Design Firms survey. The Top 225 firms generated $70.85 billion in design revenue in 2014 from projects outside their home countries, down 1.1%, from $71.63 billion, in 2013. They also had $73.48 billion in revenue from domestic projects in 2014, up 1.6%, from $72.32 billion, in 2014. The total 2014 design revenue for the group was $144.34 billion, up 0.3%, from $143.95 billion, in 2013. On the Top 225 International Design Firms list, firms are ranked based on design revenue from projects outside of their home countries, measuring their presence in international commerce. The ENR Top 150 Global Design Firms list measures total worldwide design revenue, regardless of where the projects are located. On a regional basis, Canada saw one of the biggest drops in international design work for the Top 225, down 15.0% in 2014, as the oil price drop stalled some 72 ENR July 27/August 3, 2015 enr.com Firms need to be large enough to straddle various economic cycles and invest in organic growth and technology.

The Latin American market also saw a significant decline, with international revenue falling 18.5% as the economies of Argentina and Brazil experienced slowdowns and the mining sector in Chile was hit hard. The Asian market, hit by a slowing in and a market decline in Australia, fell 7.8%. The economic turmoil in the European Union, led by the Greek bailout crisis, caused the Top 225 international designers revenue to fall 7.5% in Europe. Surprisingly, the Middle East market rose 12.0% in 2014 for the Top 225, despite a drop in oil prices and some wariness about whether as this would impact regional investment. The U.S. as an international market surged 43.8% among the Top 225. Part of this rise can be attributed to Canada s WSP acquiring U.S.-based Parsons Brinckerhoff and Australia s GHD acquiring Conestoga-Rovers & Associates. Bigger Is Better Acquisitions have been a big story in the past year. AECOM now is No. 1 on the Top 225, after acquiring last year s No. 3 firm, URS Another big move on the Top 225 is by s Power Construction, which consolidated revenue from its operating units, including Hydrochina, to rise to No. 30 from No. 126.

They include the U.K. s engineering firm Hyder plc, with some 5,000 employees, and large, Seattle-based architect Callison LLC. European firms are getting bigger. Most recently, the ongoing acquisition by Sweden s Sweco AB of Netherlands-based Grontmij NV will create a new player with 14,500 employees. After a few years of bad results, Grontmij had reached a strategic crossroad, noted firm CEO Michiel Jaski in the acquisition s announcement this June. Between 2010 and last year, Grontmij s net sales fell 20%, while its net margins dipped to 0.9% from 4.1%. In that period, staff fell by nearly a third.

Ltd., which is predominantly geared to large projects in Africa, according to Krueger. Some design firms do not see these new megafirms as a direct threat. Some of our competitors are being bought up by large conglomerates that are focused on large infrastructure and oil-and-gas projects, says Con Murphy, sector director for Ireland s. However, he says this situation has left room in the market for new design firms that provide neither the quality nor the expertise but offer lower prices, which affects pricing for everyone. Many international designers continue to be wary of price pressure. One key negative trend that is affecting the international design industry is price-driven selection, says Andy Goodwin, CEO of Australia s. He says this undervalues the design input on a project and results in an inferior project outcome and higher costs over the long term through higher construction and maintenance costs. But Murphy says many clients are slowly moving back to qualifications-based procurement after being burned by low-cost providers. This is the continuous feedback we are receiving from those clients, he says. Market Turmoil Global financial and political turmoil has many international designers on edge.

THE TOP 225 INTERNATIONAL DESIGN FIRMS Creation of the Asian Infrastructure Investment Bank and the Silk Road Fund, with $100 billion and $40 billion [respectively], is already starting to impact the development of the whole region. Yan Li, Vice President, CCDI Group. the global economy is a concern, as evidenced by the current financial collapse in Greece, the impact of the Chinese economy and, more locally, Australia s ongoing difficulties, says David Prentice, CEO of New Zealand s Opus International Political instability in some regions of the world, as in the Gulf region and geopolitical tensions in Europe, are halting international growth, says Stéphane Aubarbier, executive vice president of Assystem Group. He says financing issues in developing countries and financial debt in developed countries, especially in Europe, could cause the delay or abandonment of major infrastructure projects. Global economic turmoil has led to the overall uncertainty in countries where IBI has a presence, including Greece and, says Trevor McIntyre, global director for IBI Group. This uncertainty makes it difficult to define stable markets and ensure business success in these environments, he says. The financial uncertainty also has made bidding a challenge. As an international company, fluctuation in currency and changes in global economy are always a concern, says Park Seung Woo, CEO of Korea s Dohwa Engineering He says the weakening of the Japanese yen has made it harder to compete financially with Japanese firms. Park also says the European Central Bank s (ECB) monetary policy may affect payments made in euros. With the quantitative easing by the ECB caused by the fear of deflation in the eurozone, clients may choose to delay the payment in euros. This would lower our profits while increasing the price competitiveness of European firms, according to Park. Despite global market uncertainties, many European firms are doing well. Lars-Peter Søbye, CEO of Denmark s COWI Group, reports another good year, with orders in the transportation and infrastructure sectors booming. COWI has very healthy growth in areas we want to invest in, says Søbye, citing Scandinavia, the U.K. and COWI North America, as well as tunnels, bridges and marine markets. With sales up some 25% and margins up by around 17%, business is reasonably good, says Keith Howells, chairman of the U.K. s Mott MacDonald Groups. The water sector is good in the U.K. and North America and could be better in other regions, especially Asia, he notes. Transportation is busy globally, with lots of people wanting to do metros, he says. The energy markets over the past three years have been very strong, says McArthur of ARCADIS, citing the Middle East and Asia. The firm has a very strong position in Brazil, he adds. Mott grew to about 16,800 staff after last fall s acquisition of Bentley Ltd., an 800-person contractor in the water sector that Mott often partnered with. With Bentley, we have the potential to double the business in the next five years just in the water sector, says Howells. Søbye agrees that, with 6,400 staff, COWI is modestly sized by global standards. Where we can make a difference [is] where we are best in class, he says. The big groups really want to have us on their teams. In Europe, the U.K. is as busy as it has been for some years, says Howells.

There are also five market-based units covering the business lines, such as transportation and public-private partnerships. However, international firms are finding the U.S. a tough market to crack.

However, there is promise for the regional market with the new trade and infrastructure initiatives in the offing, including the Trans-Pacific Partnership (TPP) treaty backed by the Obama administration. Trade agreements, such as the ambitious TPP, are helping to enhance trade and investment between countries and [creating] opportunities in the international design market, says Greg Lowe, CEO of New Zealand s Beca Group Ltd. With the launch of the -backed Asian Infrastructure Investment Bank in October 2014, we expect more large-scale infrastructure projects funded by multilateral development banks [MDBs], including urban planning, railroads and industrial plants. More funding from MDBs would allow projects to take place in more regions, says Park of Dohwa Engineering. s recent One Belt, One Road initiative to fund transportation and maritime projects has had a major positive impact. The initiative covers most of Eurasia and part of Africa. This initiative targets an underdeveloped area that connects East Asia to the eurozone. Infrastructure improvement will be a prime focus, says Yan Li, vice president of s CCDI Group. Creation of the Asian Infrastructure Investment Bank and the Silk Road Fund, with $100 billion and $40 billion [respectively], is already starting to impact the development of the whole region, he says. Singapore is still active, and there s a bit of resurgence in the Philippines, while Indonesia is disappointingly quiet, says Howells.

I think India is full of the greatest opportunities for businesses in the international design market at the moment. There is so much pent-up demand for infrastructure of any kind. I believe being able to understand the local situations is the key to be successful there, says Yuichiro Motomura, CEO of Japan s PADECO But for many international designers, India remains a challenge. India has endured a lot of uncertainty coming up to recent elections, which has affected investment in projects across sectors, such as the automotive industry as well as the usually robust pharmaceutical and food sectors, says Murphy of. Murphy also notes that India has its own strong stable of designers to compete against. Success in India depends on whether the client sees us bringing added value. It is impossible to compete with local companies unless the client believes we are bringing this value, he says. The Middle East continues to offer the same old mix of opportunities and risks, says Howells. Mott is cool about Saudi Arabia, which the firm perceives as risky due to regional tensions and low oil prices. In the Middle East, we go in with first-rate contractors, adds Søbye. He sees opportunities in Qatar and also in Saudi Arabia. Some firms remain optimistic about the Middle East. Despite falling oil prices, the Gulf region, particularly in the United Arab Emirates and Saudi Arabia, is showing a diversification of markets, says McIntyre of IBI enr.com July 27/August 3, 2015 ENR 77

THE TOP 225 INTERNATIONAL DESIGN FIRMS #177 CHODAI OF JAPAN is designing the 1,408-m 3rd Bosporus Bridge and the 1,550-m Izmit Bay Bridge in Turkey. OVERVIEW Group. But with it, there is significant competition in the areas of consulting, including industrial development, transportation, infrastructure, mixed use, resorts and residential, he says. Keeping It Local For international designers, local competition and local workers and material-use policies are becoming a bigger concern. Localization constraints also have become stronger, says Aubarbier of Assystem. We believe that international expertise must be coupled with the capacity to deliver locally. Policies that favor local companies are arising in some of the most promising markets. In Indonesia, the shift of policy emphasis toward domestic aspects seems to be negatively affecting the participation of international design firms, says Motomura of PADECO Co. Financing patterns also have been evolving, particularly in developing countries. Although [Japan s] Official Development Assistance [ODA] projects have, until now, been an important part of our work, some developing countries, which used to be significant recipients of Japanese ODA, have seen their economies grow rapidly, says Mori of Chodai. Thus, these developing countries are less interested in financing projects with ODA than before and are increasingly looking to other means of funding, such as public-private partnerships and private financing initiatives, Mori says. Such developing countries have also developed their technological capabilities and can nowadays design and construct many projects that, in the past, would have required foreign assistance. The answer for many international designers is simply being local in a global market. For example, Dohwa Engineering has been opening local offices and hiring local experienced experts. Local offices have been working to keep good relations with the local contractors, while the head office provides training and production of proposal documents, says Park. n Companies By Debra K. Rubin Yank CEO Returns Down Under Richard Wankmuller, newly named CEO of Australia-based Cardno Ltd. (No. 35 on ENR s Top 150 Global Design Firms list) is an American who formerly headed North American operations for GHD Pty., also based Down Under, and had lived there for five years. He takes over the $1.1 billion-firm as it faces challenges in business results, to be announced on Aug. 18, and in changing markets in Australia and elsewhere. What are the continuing risks in Australia s economy? Are there potential market opportunities, as well? Australia remains a challenging and uneven market. The slowdown in capital expenditures in the resource sector has obviously had a significant impact in many key states. This situation has been further aggravated by recent delays and some cancellations of planned infrastructure upgrades due to changes in state governments and infrastructure policies. Even so, New South Wales is moving forward on some very impressive infrastructure upgrades. This [new work] has created a shortage of top people in some areas while fueling business uncertainty in others. It s disappointing, as it creates turmoil in our industry. We hope some delayed work will be brought back to the market. Other hopeful signs relate to the need for LNG projects to continue, such as the North Rankin gas-compression project off the western coast. WANKMULLER What is the outlook for Cardno in North America? We are well positioned to benefit from the integration activities of last year and expect to see gains in efficiencies and capabilities. We have adjusted regional staffing levels in response to the wind-down of our monitoring and remediation of the Gulf of Mexico oil-spill impacts. We have also adjusted to the dramatic drop in oil prices and begun to retool services, so they are less dependent on new investments. Recent wins are starting to replace cancelled work. In the interim, this will remain challenging, but we expect to see an improvement. What is helping Cardno to find success in the international design market? We applied our big-data management techniques developed during our oil-spill work to our work on the Inpex LNG project in Darwin. Likewise, we ve leveraged our construction-materials testing expertise developed on LNG projects in Queensland and applied [it] to projects in Texas. Cardno also just unveiled a biodiversity mapping tool to help the U.S. energy industry identify endangered-species habitats. Cardno has been developing truly innovative solutions that are also environmentally and socially responsible. This combination is right at the heart of what many clients are looking for. n How To Read the Tables Companies are ranked according to revenue for design services performed in 2014 in $ millions (*).
