Investigators are probing whether concrete strength tests were skimped on at the new Yankee Stadium, the Freedom Tower and as many as a dozen other of the city's biggest recent construction projects.
The probe's target is Testwell Laboratories, one of the area's leading concrete-testing companies.
Manhattan prosecutors believe the company overbilled on some of its testing services, and billed for other tests that were not performed at all, according to one investigator who asked not to be identified.
New concrete is routinely tested as a safeguard against mixing and pouring irregularities that could affect durability and strength, said the source.
(P.S. I used to love those polka-dotted cement trucks when I was a kid. They seemed to be everywhere back then.)
