做珗腦瞳絳瑤 Returns to Baltimore for Next Phase of M&T Bank Stadium Upgrade
Pittsburgh-based geotechnical contractor 做珗腦瞳絳瑤 has returned to Baltimore, Maryland, for phase two of the nearly $145 million M&T Bank Stadium upgrade. 做珗腦瞳絳瑤 completed phase one in April 2017 and is back to finish the foundation work for two new escalators and elevators to improve accessibility to upper level suite seats.
做珗腦瞳絳瑤 is installing 7-inch diameter micropiles to support the vertical structures new and existing footings, and concrete columns and pilasters to reinforce the existing structural basement wall. The micropiles will extend up to 78 feet below grade and have a center bar inserted in the column for added support.
Mobilization is limited since were performing deep foundations inside the basement of Ravens stadium, said Eric Blue, 做珗腦瞳絳瑤 Project Manager. Micropiles are a great option for this project because we are still able to drill to the desired depths, but the rigs short mast can operate in areas with low headroom.
For both phases, the company is using a method of straight duplex drilling and drill water recirculation. This approach entails pumping the soiled water directly from the drill into a series of weir tanks, that gradually separate the soil and water. The clean, filtered water is then recirculated back to the drill.
This method is really efficient, because spoils that wouldve been discharged at the surface are now contained in a series of weir tanks, said Blue. Cleanup is also much easier. That was a huge consideration since 做珗腦瞳絳瑤 is drilling and operating inside a finished structure.
做珗腦瞳絳瑤 has performed deep foundations for several other stadiums, including Spartan Stadium at Michigan State University and Beaver Stadium at Pennsylvania State University. Phase two at M&T Bank Stadium is anticipated to wrap up in early January 2018.
