Points Earned for IAQ Test?

We haven't tested yet using v4 but used to often in 2009. We always ended up passing, though a few times we failed in one area because something from the punch list was ongoing. Once we failed a PM test when somebody needed to cut into the drywall to retrieve a broken cable from the conduit it got stuck in and another time we failed a VOC test because the hinges on an emergency exit to the basement had to be flipped and we were using Bondo type material. Both passed on retest after a day or two. We pursued the low-VOC credits and flushed the building leading up to the test. I'm interested to hear if v4 is more difficult to achieve. FYI - I reached out to our regular tester and he said this about costs: Small v3 projects such as what you describe (20 k SF, 3 story) range from $2,200-$3,000. v4 is a nightmare with no labs stepping up to offer a package of analyses that will fit the requirements. Using a patchwork of tests and labs, the cost would be approximately $7,000-10,000 per building.
