Boston, MA – June, 2015
Hennigan Engineering Company, Inc. was retained by a National Design/Build Contractor to perform Emergency Response Video Inspection and blockage removal from a municipal pipeline linked to their construction of an addition to an active hospital in downtown Boston, Massachusetts. The blockage came on unexpectedly during construction and was sufficient to cause back-up into active/occupied spaces within the hospital.
Two other contractors failed to solve the problem after several days of trying, then Hennigan Engineering was called into the situation. The affected wings of the hospital were in imminent risk of being shut-down by local Public Health officials as well as the City’s Engineering Department. The municipal pipe was approximately 15 ft. below two heavily travelled city streets.
If Hennigan Engineering was not successful in locating and removing the blockage, our client would have been mandated to excavate the municipal pipe and replace approximately 150 ft. of this 24 in. pipe. This would have been a significantly detrimental direct cost and project delay cost for our client.
What two other pipeline service contractors failed to achieve over the course of three days; Hennigan Engineering’s specialized crew and equipment achieved in less than one day. The blockage was found to be comprised of construction debris including PVC pipe segments and whole bricks. The debris was removed without shut-down of the affected hospital wing or further construction delays.
It is this type of consistently cost-effective and reliable performance by Hennigan Engineering that continues to set the firm above all others.
