QT joined up with the Pulice/Granite Joint Venture (PGJV) construction contracting team on ADOT’s $100 million Design-Build project that constructed HOV lanes on the L202 (Santan) Freeway between Gilbert Rd and the I-10 Freeway in Chandler, Arizona. In general, this 10 mile long project involved significant quantities of excavation and controlled fill placement; drainage feature and utility relocations; several new retaining walls; asphalt and concrete pavement sections; new concrete median barrier, roadway lighting, signing, and striping. In addition, this project included 5 new major bridge structures to connect the new L202 HOV lanes to both the existing L101 and I-10 freeways.
As is typical for alternate delivery projects of this size and scope, the ADOT contract requirements mandated that the design-build team develop and utilize a formalized Construction Quality Control Plan. QT initially worked closely with PGJV to develop this plan, worked through the review and revision process with ADOT, and ultimately implemented a plan that encouraged teamwork between QT inspection and testing personnel, PGJV production personnel, and ADOT oversight personnel. Drawing heavily from existing ADOT inspection tools and documentation standards, our plan for maximizing quality and minimizing non-compliance and potential re-work situations was well received by ADOT.
UPDATE: The L202 (Santan) project ended in 2012. Due to our success on that project, QT again teamed up with the Pulice/Granite Joint Venture to win a second $100 million Design-Build freeway project, the L202 (Red Mountain) Freeway between L101 and University Dr in Mesa, Arizona. On this high profile alternative delivery project that began in fall of 2014, QT is once again implementing our proven Quality Control Program and providing all inspection, testing, and related documentation.
