"The whole landscape is going to change," says Mysore Nagaraja, president of capital construction at the Metropolitan Transportation Authority.
At peak construction on all of these projects, a total of four tunnel boring machines (TBMs) will be grinding through the Manhattan bedrock at the same time: two on East Side Access already in operation, and, later this year, one on the No. 7 extension and one on the 2nd Ave. Subway.
The four TBMs may not seem particularly remarkable when compared to Shanghai, China, with a population approaching 30 million people ("they have 50 TBMs running at the same time," says Nagaraja) but it's unprecedented in the city's history.

"The greatest challenge right now is that the construction industry is so saturated and so much work is going on not only in New York City, but all over the country and all over the world," says Nagaraja."The resources and the contractors [we need to get] have been a challenge, and the prices are much higher that we expected them to be."
In addition to putting a strain on management and consulting firms in terms of the sheer amount of work, the number of projects running concurrently limits the skilled labor available to do the job."The good contractors always depend on the best skilled labor in the industry the A-teams," says Nagaraja.

However, the scope of New York's new construction is such that all of MTA's projects, for example the 2nd Ave. Subway, East Side Access, and the No. 7 extension amount to a mere 15 % of all work in the city, according to Nagaraja.

"New York City is 100% developed - both under ground and above ground," says Nagaraja.
...
"We have been very transparent," says Nagaraja."And we need to be."
"Once we have the launch box [for 2nd Ave. Subway] between 92nd and 96th Sts., once the TBM is lowered, the TBM will be doing work underneath," he explains.
...
"We have not done these kinds of projects in a long time," says Nagaraja.
