First construction phase of Detroit´s M-1 RAIL completed
Published: Mon, 2014-12-08 11:00M-1 RAIL has completed its first phase of construction between Campus Martius Park and Grand Circus Park in downtown Detroit. After the floats, clown corps and spectators have departed on Thursday, vehicle traffic will once again be able to travel the Downtown stretch of Woodward Avenue.
Construction Manager/General Contractor Stacy and Witbeck, Inc., in partnership with the Michigan Department of Transportation (MDOT) and local construction companies and suppliers began construction of the Downtown portion of the rail system in late July.
Several Detroit-based firms, including Hart & Associates Construction and Farrow Group have been part of the construction. After securing the work zone and erecting pedestrian fencing and bridges, detailed surveying was performed by crews prior to moving in heavy machinery to remove layers of asphalt and concrete to make way for the new track slabs.
Over the course of four months in downtown, construction crews installed electrical and telecommunications conduit.
They received and welded then steel track into 560-foot sections. After that they moved it onto Woodward Ave to reinforce the steel track with an elastomeric grout pad or “rubber boot,” which provides vibration dampening and noise reduction.
They strengthened also the imbedded rail with special thermite rail welds and they built and installed a supportive rebar substructure over the track to better support the concrete.
After that they poured, levelled and texturized a high-performance, faster-curing type of concrete and removed layers of old asphalt. The team resurfaced then it with high-quality asphalt; and installed granite curbs, reinforced manholes and completed temporary pavement striping.
