Giken Uses Non-Vibratory, Minimal Noise Press-in Pile in Manhattan

Steel pile driving equipment retains a reputation in the USA for being noisy, vibratory, and disruptive. A recently completed site project in New York City’s borough of Manhattan was initially designed using a soil-mix method in part due to New York City’s requirements for foundation construction near existing structures. However, Giken America put forward a value engineering proposal for a steel sheet pile wall utilizing the non-vibratory, low noise, confined access Press-in method. The proposal offered reductions in both construction time and cost and was an excellent opportunity to raise awareness of the Press-in method’s applications for residential and urban areas. 
HRC 670 Field Installed T-Heads to Solve Rebar Elevation Issues
One of the main challenges deep foundation contractors face is the coordination of rebar cage lengths and top of cage elevations. Additionally, designs commonly require hooks at the top of the cage where the vertical rebars terminate. Headed Reinforcement Corp.'s 670 T-Heads are a great alternative to hooked anchorage. They help reduce the risk with setting cages at the wrong elevation and can be used for field fixes with the cage in place! HRC 670 T-Heads reduce congestion, making installation of adjacent reinforcing easier and allowing for better concrete consolidation! HRC 670 T-Heads can be the problem solver on your next project! 
PPT Develops Centering System Using “W” “H” or “I” Beams in Large Diameter Shafts
As larger diameter shafts grow in popularity, the need for internal reinforcing hardware becomes a concern. Therefore, Pile Protection Tops (PPT) developed a centering system for these extremely heavy, long beams that require proper alignment. Several versions of this system are available based on shaft diameter, beam specifications and soil types.
Specrete Introduces Tremie Concrete Admixture System
Specrete introduces a system of admixtures designed to be used together to improve the properties of tremie concrete. Micro-Aid TCA, Flo-Aid HR and Flo-Aid EWT combine to produce a stable mix that is pressure filtration and bleed resistant with an extended working time. This system of products is used to meet the recommendations of the EFFC/DFI Guide to Tremie Concrete for Deep Foundations. In the last couple years, this system was utilized in several projects, including the Westerly Storage Tunnel in Cleveland, Ohio, and the Storm Water Storage Facility along I-35 in Minneapolis, Minnesota.
