Here’s one company that didn’t live up to its name.

Testwell Laboratories was found guilty today by a Manhattan jury of falsifying records of some 3,000 concrete-strength test results on hundreds of construction sites across the city — including the new Yankee Stadium — and sending unqualified workers to do on-site assessments of newly erected steel.

Testwell CEO Reddy Kancharla was also found guilty, while one of his associates, Wilfred Sanchez, was acquitted.

The jury did not return a verdict against another associate, William Barone, and was ordered by the judge to continue deliberating.

The DA’s office argued that concrete tests that should have taken seven to 56 days were done overnight.
