Sundt is hitting the road for another extension of the Valley Metro Light Rail system in Greater Phoenix.
The 1.9-mile Gilbert Road Extension in Mesa will stretch the system beyond the Central Mesa extension on Main Street to Gilbert Road. Scheduled for completion in 2019, the $113 million transportation project consists of two stations and a park-and-ride on the west side of Gilbert Road. The project will provide the ability to draw more light-rail passengers from the East Valley and bring more development opportunities to central Mesa.
The joint venture with Stacy and Witbeck will construct a roundabout on the route. The multimodal roundabout allows for cars, bikes and pedestrians to move freely, and when a train is present, the east and west traffic remains free-flowing. This innovative traffic control measure is the first of its kind at a four-way intersection on a light-rail project in the U.S.
Construction on the extension started in October 2016. Temporary lighting and traffic lights have been installed along Main Street from Mesa Drive to Gilbert Road and the median has been removed to make way for underground utility work.
The joint venture team recently completed the award-winning Northwest Extension. In 2008, the team completed more than half of the original 20-mile starter section of the Valley Metro Light Rail transit system (Line Section 4 and Line Section 5), plus the system’s maintenance and operations facility.

Sundt’s joint venture with Stacy and Witbeck on the Northwest Extension was delivered three months ahead of time and on budget.
Completing a challenging project requires a team effort. Sundt’s teamwork with Stacy and Witbeck produced a needed extension for a light-rail system in the Phoenix area and many awards, including a 2016 Arizona Transportation Partnering Excellence honor.
The joint venture was recognized for Valley Metro’s Northwest Light Rail Extension, a 3.2-mile addition to the Valley Metro light rail system that was completed last year. The award was presented at the annual Roads & Streets Conference in Tucson last week.
The transportation project was delivered three months ahead of schedule and on budget despite the challenges of being located in an urban area with a high volume of vehicles and pedestrians. Sundt/Stacy and Witbeck also coordinated more than 20 months of utility construction to remove and replace 100 percent of the water, sewer and storm systems.
To keep the community informed, the team developed a smartphone app to provide project updates and information about changing traffic control. The app also contained coupons, business promotions and route information.
The awards recognize teams that demonstrate a high degree of achievement through their practice of the partnering principles and application of partnering processes in the transportation industry.

The White Tanks project was once a massive area of dirt and mud.
Choosing a new project delivery method kept the Maricopa County Flood Control District from seeing its budget wash away during work on the White Tanks Flood Structure in Buckeye, Arizona.
In the past, the District constructed similar projects using Design-Bid-Build and sometimes faced change orders that nearly doubled initial bid values because of outside agency inspections during construction.
It’s now a flood control project that is coming in on time and on budget.
On White Tanks, the District decided to try Construction Manager at Risk and selected Sundt. Our Transportation Group partnered with agencies including the Arizona Department of Water Resources and the National Resources Conservation Service to write specifications exactly as the District expected, lowering the chances of costly change orders.
“It worked well,” said Preconstruction Manager Jeffrey Hamilton. “The only change order relating to additional cost was because of a flood event, and the District had a contingency to cover that.”
The joint venture with Rummel Construction consists of widening and extending an existing flood structure and adding upgrades, including an architecturally enhanced auxiliary spillway, drop inlet structures and principal outlet structures. While the initial contract value was $25.3 million, the team is looking to bring the cost down by about $1 million.
We’re delivering client value in many other ways, too, including using drone technology to provide required survey information to verify completed work for our payment purposes.
“This would be a difficult and costly task with a survey crew,” Project Manager Ryan Vlach said. “We found a drone company that was able to fly the site and provide the necessary information at a fraction of the time and cost.”
Preconstruction ended in January 2016 and construction began the next month. Even with a small change order extending the contract until August, the team intends to finish work by June.

The Northwest Extension is a 3.2-mile addition to the Valley Metro light rail system in the Greater Phoenix area.
Awards are rolling in for Sundt’s Valley Metro Northwest Extension project, including two from the prestigious Build America program.
The $160 million project won in the transportation category and also earned the Marvin M. Black Partnering Excellence Award, which is presented annually to projects that epitomize the principles of partnering. The awards were presented during the Associated General Contractors of America (AGC) National Conference in Las Vegas earlier this month.
“These awards, which are selected by a group of our peers, represent the best projects construction has to offer,” said Project Manager Chris Elison. “It’s an honor to be recognized by other great contractors for the work we performed.”
The project is a 3.2-mile addition to the Valley Metro light rail system in the Greater Phoenix area. The Sundt/Stacy and Witbeck JV work is the fourth project the team has finished as part of Valley Metro’s program. Scope included curb-to-curb replacement of water, sewer, storm, electrical, communication and gas utilities, roadway widening and installation of embedded double track with an overhead catenary system, train signals, three traction power substations and traffic signals. The project added three stations and a park-and-ride at Dunlap Avenue, and 6.4 miles of sidewalks, curb and gutter and pavement.
Build America awards honor AGC members who perform the nation’s most impressive construction projects ranging across the building, highway and transportation, utility infrastructure and federal and heavy divisions. Sundt’s most recent Build America honors came in 2015 in the environmental enhancement category for the Ocotillo Brine Reduction Facility renovation construction project in Chandler, Arizona, and the highway and transportation renovation category for the West Seventh Street Bridge in Fort Worth.

There’s a lot of progress to report on the Northwest Extension, the 3.2-mile, $162 million expansion of Phoenix’s light rail system. The Sundt/Stacy and Witbeck team is performing the last stretch of roadway widening and maintaining the schedule in spite of recent heavy rains. Track installation is ongoing and the structural steel has been set for the Dunlap and Glendale stations. Construction of the Park & Ride lot, which began earlier this month with utility work, is expected to be complete in September. Roadway widening is expected to be complete mid-summer. Track placement should finish up in late summer or early fall.
