The Tip O’Neill tunnel was built as part of the Big Dig. Its roadways make up the central artery of transportation under downtown Boston. As part of maintaining this crucial roadway Specialty Trades was contracted to preform repair and replacement of delaminating fireproofing throughout the tunnel.

This job presented many logistical difficulties that needed to be addressed upfront, because of the heavy usage of the highway all work needed to be preformed during low impact hours which turned out to be between 12AM-5AM. Each night the work must be done between those hours and the road had to be fully operational by the time morning traffic hit.
