The City of Philadelphia’s Water Department had a problem, and the obvious method of core drilling was ruled out as a solution due to limited access. So, an alternative solution was needed.
A specialty concrete sawing and drilling contractor was recently called to Port Manatee on the southeastern edge of Tampa Bay, Florida, to cut and remove a 600-foot-long, 44-foot-wide section of a 3-foot-thick concrete wharf and seawall.
A new 1,600-foot-long steel bridge had been open to traffic for several months before an oversight in its design was identified and needed immediate attention.
When a general contractor needed to remove 15,000 square feet of 16-inch-thick concrete weighing more than 3,000,000 pounds in one month, they contacted a professional sawing and drilling contractor.
Contractors use diamond wire to cut and remove large sections of heavily-reinforced concrete on piers, dams, bridge sections and in areas where work space is restricted. Of these restricted work areas, none present more challenges than when the structure is underwater.
The use of understrength concrete during the construction of a new motorway off-ramp meant a support beam and its surrounding concrete had to be replaced before the ramp was opened to traffic.
