MCDOT, Northern Parkway, Phase I

Northern Parkway, Phase I, was a $42 million conventional bid-build project constructed between February 2012 to October 2013 by the Maricopa County Department of Transportation (MCDOT).  This initial portion of the Northern Parkway runs east/west from Sarival Avenue, just east of ADOT 303L, to Dysart Road, and is located immediately north of Luke Air Force Base and Northern Avenue.  The project consisted of 4 miles of new alignment roadway construction; grade separations at Sarival Avenue and BNSF Railroad; and at grade connections at Reems Road and Litchfield Road. The work activities involved major structures and MSE walls; high volume roadway excavation, embankment with settlement requirements, special subgrade preparation, and paving; drainage and irrigation channels; and roadway lighting, signing and traffic signaling.  This complicated project required significant coordination effort between the project administration team, the contractor, MCDOT, the cities of Glendale and El Mirage, BNSF Railroad, the Maricopa Water District (MWD), the Flood Control District of Maricopa County (FCDMC) as well as the surrounding farms.

Quality Testing, LLC (QT) was a part of the Construction Management team led by Tristar.  Robert Clifford, a key member of QT’s management team,  provided construction management over the Northern Parkway project activities associated with the earthwork, paving, drainage and MSE wall construction for the BNSF overpass structure.  QT staff was also responsible for the materials management duties such as tracking all material test data, assessing materials compliance, maintaining a certification log, and to a large extent, provided the database tools and expertise for managing other project data including submittals, transmittals, change orders, and quantity tracking for pay estimates.
