Each architectural firm has its own benchmark on measuring success. Some benchmarks may include revenue earned, market saturation, building the brand, customer satisfaction, employment levels, team work and the firm’s ranking on the international landscape. The mission statement and vision of each firm guides employers and employees in what direction to navigate the firm’s growth. For many firms, one of the top priorities, is selling and marketing the firm to achieve more revenue.
While marketing is essential, some firms merge with other firms to attain greater accomplishments. The advantages of mergers and acquisitions include more revenue, cost efficiency, tax gains, administrative benefits and a growth in market share. This is illustrated in the case of AECOM which topped the list after acquiring URS Corporation, the firm’s former rival, in October of 2014. It was a $6-billion deal and it is documented as the biggest publicly traded company in Los Angeles. AECOM has designed and managed well-known structures, such as World Cup stadiums in Brazil and huge sports arenas. URS also has a strong business in federal contracting with the U.S. Army and Energy Department.
On the day of the merger, Michael S. Burke, AECOM Chief Executive Officer expressed, “Today is an exciting and historic day – for our industry, for AECOM and URS, and for our nearly 100,000 people around the world who are serving our clients in over 150 countries. Beyond the compelling benefits that this transaction creates for our combined clients, stockholders and employees, the combination of AECOM and URS dramatically accelerates our strategy of creating an integrated delivery platform with superior capabilities to design, build, finance and operate infrastructure assets around the world.”
