Dive Brief:

• The Real Deal has ranked New York City's largest general contractors, based on Department of Buildings data from 2012 to 2017, and, once again, AECOM Tishman came out on top.
• The company built nearly 14 million square feet of ground-up construction in that five-year time period, almost twice that of its closest competitor Turner Construction, which built nearly 8 million square feet.
• The Real Deal identified Structure Tone as the city's top alteration and renovation construction company, with a total of $2.6 billion worth of work over the last five years. AECOM Tishman came in fifth in that category, with A&R permits totaling $799 million.

Dive Insight:

The AECOM Tishman brand is the result of major acquisitions by AECOM. The construction giant purchased Tishman in 2010 and Hunt — the general contractor behind projects such as the Atlanta Falcons' $1.5 billion Mercedes Benz Stadium — in 2014. AECOM announced it February that it would rebrand those acquisitions as AECOM Tishman and AECOM Hunt.

AECOM Tishman is currently underway with the $3 billion One Vanderbilt tower in New York, while AECOM Hunt is working as a joint venture partner with Turner on construction of the Los Angeles Rams' new $2.5 billion stadium in Inglewood, CA. 

In a previous Real Deal analysis of New York building permit data in 2015 alone, it found that Tishman had secured permits for eight projects, representing 8.243 million square feet and 270 stories of construction, which was three times the square footage of the next runner up.

A significant driver of construction activity in New York is A&R work. According to an April New York Building Congress report, that market, which NYBC President and CEO called "the unsung hero" of the city's building boom, totaled $9.3 billion in 2016, the third consecutive year that the segment has increased in value. 

Structure Tone is not only the leader in A&R work in the city, but it's also making inroads in sustainability. In March, the company's Manhattan headquarters was the first New York City property to earn the International WELL Building Institute's WELL certification. The Gensler-designed, 82,000-square-foot space won the Silver designation by incorporating such features as efficient mechanical systems, point-of-source water filters, circadian rhythm lighting and optimization of noise levels.
