Replacing Bridge Bearings without Interrupting Traffic to the Second Bosphorus Bridge
Located on the O-2 Highway in Istanbul, the Sadabad Viaduct is a connecting motorway to the Second Bosphorus Bridge; the 19th longest suspension bridge span in the world. Approximately 400 bearings needed to be replaced on the Sadabad Viaduct while the road remained continuously open to traffic.

Pulling Pins on an Oil Well Casing Elevator Spider
The borehole of every oil well drilled must be cased with a durable material to prevent contamination and provide structural support during drilling. An elevator spider is used as a guide to aid in centering each casing. The pin on the elevator spider must be replaced after every drill in order to remove corrosion, dirt and grime built up during drilling. MOISS’s existing process for removing the pin took up to 4 hours and required continuous hammering.

Lifting and Installing the Deck Sections of the Golden Horn Metro Bridge
The Golden Horn Metro Bridge is a 936 m (3,071 ft.) long cable-stayed bridge which spans the Golden Horn waterway in Istanbul, Turkey. Portions of the bridge deck rotate in order to permit large shipping vessels through the waterway. The rotating bridge deck segments were fabricated off-site and floated in on a barge. The 300 ton deck sections needed to be lifted off the barge nearly 17 meters and installed into position.

Turbine and Generator Installation at a New Power Plant in Libya
Çal?k Enerji is constructing a new simple-cycle power plant with a 542 megawatt capacity in Khoms, Libya. The Sarilar Group was tasked with installing a GE gas turbine weighing approximately 280 tons and a GE generator weighing approximately 214 tons. Installation required lifting the turbine and generator over 5 meters high and lowering into position on a concrete foundation.

Installing Pylon Sections of a Cable-Stayed Bridge with a SyncHoist
Gotowski constructed a 200 meter long cable-stayed "University Bridge" to connect two parts of Bydgoszcz separated by the Brda River. The bridge's design requires the erection of two 68 meter tall pylons (towers) to support the bridge deck. Constructed in sections, the pylons weighed 90 to 130 tons and needed to be positioned with precise accuracy.

Hydraulic Drive System for Las Vegas Observation Wheel
Erecting the Las Vegas High Roller Observation Wheel included installing the 28 passenger cabins. To ensure accurate and safe installation, a hydraulic drive system was needed to turn the wheel for correct positioning and placement. The drive system would also be critical in the overall rotation of the wheel, which would serve as the permanent operating system. Enerpac and Schwager Davis Inc., a specialty contractor, worked together to supply a reliable system solution.

Box Girder Launching System on the I-95 Whittier Bridge
Constructed in 1951, the John Greenleaf Whittier Bridge is currently in the process of being replaced by a new bridge compliant with current safety standards. The high traffic bridge connects Newburyport and Amesbury via I-95 over the Merrimack River. Walsh Construction is employing a rail mounted gantry crane system to simplify the placement of the steel bridge girders and precast deck to create the approach spans. Two 6 foot tall, 960 foot long temporary support steel box girders will be launched across temporary piers to create a rail system for the gantry crane to operate on during the approach span construction. The steel box girder arrangement will be moved after the placement of each approach span. It’s critical that the two 550 ton temporary steel support box girders move in unison in order to prevent binding or misalignment of the gantry crane operating on top of the rail system.
