 An ominous foreshadowing of cost overruns, Miami Access Tunnel requested money from a $150 million reserve fund in July 2011 for the unexpected need to grout the limestone beneath the surface so that the tunnel boring machine cuts more smoothly.This request alarmed new Miami-Dade Mayor Carlos A. Giménez when it was brought up at his first commissioners meeting as mayor on July 7.The contractor stated that they will continue without the additional requested money if FDOT denies it, but it may end up as a court case as the contractor seeks it later.
