Mystic River Bridge Rehab Team Receives Award for Engineering Excellence

The American Council of Engineering Companies of Connecticut recently awarded Cianbro and TranSystems the “Grand Award for Engineering Excellence” for the Mystic River Movable Bridge Rehabilitation Project.  

The American Council of Engineering Companies of Connecticut is the leading organization for the business and professional interests of consulting engineering firms in Connecticut. The “Grand Award for Engineering Excellence” is awarded annually to a firm whose project demonstrates the ability to exceed the client’s needs, provide a strong benefit to the public, and find unique ways to overcome complex issues. The award, typically given to engineering firms, was shared by TranSystems and Cianbro because of TranSystems' recognition of the collaborative effort from both companies to work together to assess and overcome challenges as they arose during the accelerated pace of the project.

The award was presented to TranSystems and Cianbro on January 20th at the ACEC/CT Engineering Excellence Awards Dinner in Middletown, Connecticut. Matt Hebert and Alan Fisher accepted the award on Cianbro’s behalf. The projects entered are judged by the following criteria: Meeting or exceeding the client’s needs, Social, economic, or sustainable design considerations, originality, and complexity. Winning the Connecticut award qualifies the project to be considered for the National ACEC Engineering Excellence Award to be awarded in April.  

The Mystic River Bridge Rehabilitation project was comprised of three winter outages for the bridge to navigation traffic and traffic restriction. During the first season, crews performed a complete blasting and painting of the bridge. The second year brought about extensive steel repairs and the jacking and re-aligning of the counterweight balance truss. During this process, steel false-work was erected from the existing bridge and substructure to support the 600 ton truss and counterweight structure. The support allowed the counterweight structure to be realigned with the rest of the structure and facilitated the replacement of the counterweight trunnion bearings and balance link arms and bearings. The original design called for a pile supported structure in the riverbed to support the load and alignment work of the truss. Cianbro proposed an alternative which was embraced by the engineer and the owner, since the plan would reduce the risk to the stability of the bridge as well as to surrounding structures while reducing the timeframe in which the work had to be performed. The third year consisted of a complete removal of the existing control house and support steel, installation of an entirely new electrical and controls system, and a complete replacement of the operating machinery. The team also completed additional steel repairs and the installation of a new vehicle barrier gate to protect traffic approaching from the east during a bridge opening. Again, the two companies worked together to discuss challenges as they arose and came up with solutions which could be implemented without negatively impacting the project schedule. The project was a huge success for the owner, engineer, and contractor. During each of the three seasons, the work was completed on time or ahead of the April 15th U.S. Coast Guard required completion date for the bridge to be operable again. The success of this project is a testament to what can happen when people are willing to work together for a common cause. 

TranSystems is an employee-owned engineering firm with offices throughout the country, providing clients services in all modes of transportation, architecture, engineering, planning, real estate, security and management consulting.  

Congratulations to the entire Mystic River Bridge Rehabilitation Team: Scott Tierney, Matt Hebert, Kim Sieber, Alan Fisher, Bob Courtney, Tom Gilbert, Kevin Donovan, Mark Zagrobelny, Joanna Pyun, Joe Clough, Amanda McDermott and Charlie Nutter.
