Boston – The American Council of Engineering Companies of Massachusetts (ACEC/MA) has named Jacobs as a 2019 bronze award winner for engineering excellence for their work on the Middleboro Secondary Trestle Replacement MP 15.95.
Using an innovative pre-cast concrete culvert instead of a traditional bridge to replace the deteriorating Middleboro timber trestle, Jacobs minimized disruption to a vital commercial freight line and saved approximately $4 million in construction costs.
The box culvert design maintained the span and flow channel width, increased the flow channel height to above the 100-year storm FEMA requirement, restored the right-of-way to its original two-track configuration, and was installed within the CSX-mandated four-day operating outage despite an unexpected snow storm.
The new ballasted deck which replaced the existing open deck is virtually maintenance free and extends the culvert’s service life. An international firm, Jacobs has Massachusetts offices in Boston and Bourne.
The 2019 Engineering Excellence Awards were announced at the recent ACEC/MA Engineering Excellence and Awards Gala with special guest emcees Jonathan L. Gulliver, highway administrator at MassDOT; and Frederick A. Laskey, executive director of MWRA.
