>An accountant discovered the discrepancy while reviewing the budget for new train platforms under Grand Central Terminal in Manhattan.

>The budget showed that 900 workers were being paid to dig caverns for the platforms as part of a 3.5-mile tunnel connecting the historic station to the Long Island Rail Road. But the accountant could only identify about 700 jobs that needed to be done, according to three project supervisors. Officials could not find any reason for the other 200 people to be there.

>“Nobody knew what those people were doing, if they were doing anything,” said Michael Horodniceanu, who was then the head of construction at the Metropolitan Transportation Authority, which runs transit in New York. The workers were laid off, Mr. Horodniceanu said, but no one figured out how long they had been employed. “All we knew is they were each being paid about $1,000 every day.”

>A Dizzying Maze of Jobs

>The reasons for the M.T.A.’s high costs start with the sheer number of people employed.

>Mike Roach noticed it immediately upon entering the No. 7 line work site a few years ago. Mr. Roach, a California-based tunneling contractor, was not involved in the project but was invited to see it. He was stunned by how many people were operating the machine churning through soil to create the tunnel.

>“I actually started counting because I was so surprised, and I counted 25 or 26 people,” he said. “That’s three times what I’m used to.”

>The staffing of tunnel-boring machines came up repeatedly in interviews with contractors. The so-called T.B.M.s are massive contraptions, weighing over 1,000 tons and stretching up to 500 feet from cutting wheel to thrust system, but they largely run automatically. Other cities typically man the machine with fewer than 10 people.

>It is not just tunneling machines that are overstaffed, though. A dozen New York unions work on tunnel creation, station erection and system setup. Each negotiates with the construction companies over labor conditions, without the M.T.A.’s involvement. And each has secured rules that contractors say require more workers than necessary.

>The unions and vendors declined to release the labor deals, but The Times obtained them. Along with interviews with contractors, the documents reveal a dizzying maze of jobs, many of which do not exist on projects elsewhere.

>There are “nippers” to watch material being moved around and “hog house tenders” to supervise the break room. Each crane must have an “oiler,” a relic of a time when they needed frequent lubrication. Standby electricians and plumbers are to be on hand at all times, as is at least one “master mechanic.” Generators and elevators must have their own operators, even though they are automatic. An extra person is required to be present for all concrete pumping, steam fitting, sheet metal work and other tasks.

>In New York, “underground construction employs approximately four times the number of personnel as in similar jobs in Asia, Australia, or Europe,” according to an internal report by Arup, a consulting firm that worked on the Second Avenue subway and many similar projects around the world.

>That ratio does not include people who get lost in the sea of workers and get paid even though they have no apparent responsibility, as happened on East Side Access. The construction company running that project declined to comment.
