The examples above are very typical for production builders.  The construction supervisor in most cases expects the concrete contractor to install the moisture barrier correctly, but he does not inspect the work himself.  All of these photos were taken after the city inspector and the builder's third-party inspector had "passed" the make-ready.  What this means to you is that you are guaranteed water will be wicked-up through the concrete (can go as high as 300 ft.) and will be present underneath your flooring at the areas not properly protected
