Jack Up System Lifts 1,500-ton Span on Fore River Bridge
No one would call the temporary bridge that was constructed in 2002 over the Fore River between Quincy and Weymouth, Mass., a work of art. The bridge replaced a 1936 Art Deco gem when it could no longer safely carry the 32,000 cars that cross the river each weekday.

Jacking System Slides the Holbrook Canal into Position
Minimizing the amount of time state highway 266 was shut off to traffic was a primary objective during the reconstruction of the bridge structure over Holbrook Canal. Utilizing an innovative Accelerated Bridge Construction (ABC) method Kiewit, Jacobs Engineering and the Colorado Department of Transportation developed a plan to build the replacement bridge adjacent to the existing bridge. The new bridge was initially used as a detour while the deficient bridge was demolished. Once demolished, the new bridge was then closed to traffic and needed to be slid into the position of the original bridge.

Quickly Removing Hundreds of Corroded Carriage Bolts with a Hydraulic Nut Splitter and Cordless Pump
Hundreds of vineyard line posts needed to be disassembled and removed. Many of the nuts had rusted onto the carriage bolt holding the vineyard trellis arms. Unbolting them was very time consuming, and faster removal methods such as grinding or torches were dangerous and posed fire hazards.

Jacking & Skidding a Tunnel Boring Machine for the Next Drilling Phase
In 2013, Jakarta, the capital city of Indonesia, broke ground on a mass rapid transit (MRT) system in hope to alleviate the city’s traffic congestion. The rail-based MRT is expected to stretch across over 108 kilometers. A tunnel boring machine (TBM) is being used to construct the underground routes. One of the critical phases of the tunnel construction is the pass through, in which the TBM needs to be moved through the underground stations to be relocated to the next drilling position.
