Making Progress Against Our Goals
April 12, 2018
In the early hours of March 26, Balfour Beatty's Southeast Rail Extension (SERE) project team in Denver, CO successfully completed a major milestone on-site. Over a nine-day track shutdown, crews from the SERE project and additional crews from the North Metro Rail Line project worked around-the-clock to tie the new extension into the existing Regional Transporation District's light rail system. The SERE project adds 2.3 miles and three new stations to the existing Southeast light rail transit line and extends service on the E, F and R lines from Lincoln to SkyRidge, Lone Tree City Center and RidgeGate Parkway. The $140 million SERE light rail extension will open for revenue service in 2019.
While completing the required work in the tight nine-day work window is a remarkable feat on its own, the team measures the operation’s success by its safe completion. Throughout the continuous nine-day schedule, Balfour Beatty displayed its strong commitment to Zero Harm by achieving more than 6,000 manhours in 108 12-hour shifts without a single safety incident.
The team’s nine-day scope of the work involved transforming the existing 1,200-foot long double track rail tracks into a 1,600-foot long double track with a new pocket track running down the middle. Crews removed the existing tracks and constructed new track with universal crossovers tying into the new pocket track. Balfour Beatty’s team also built a new overhead catenary system and installed a new train control system along with a new relay house. Upon completion of construction, the team performed comprehensive testing to ensure the work met the agency requirements for revenue service.
Ultimately, after the conclusion of systems testing, Balfour Beatty completed all of the required tie-in work on schedule and trains commenced their routes on the new part of the system.
“Everyone on the Balfour Beatty and subcontractor teams demonstrated a strong commitment to safety throughout this coordinated operation,” said Anders Lindgren, project director for SERE. “We prioritize safety throughout every aspect of the work, but the team’s safety focus during this 24/7 work period truly made the cutover operation a success.”
Congratulations to the SERE and North Metro team members who safely completed this complex transit cutover on time.
