Stantec to rehabilitate major Boston sewer tunnel

BOSTON

Stantec has been retained to engineer rehabilitation of a major sewer tunnel running beneath a densely populated section of the city.

The firm will redesign the West Roxbury tunnel, a 12,500-foot-long, 84-inch-diameter rock tunnel that has become severely corroded over time.

With depths of up to 220 feet and limited points of access, the project requires carefully planned logistics.

It marks the largest and most complex linear infrastructure rehabilitation project ever awarded to the firm.

“With so much focus lately on improving our country’s infrastructure, now is an especially opportune time for a job of this magnitude,” said Bill Powers, Stantec’s project manager.

Construction is scheduled to get under way in 2012 on the estimated $30 million (US) project. Completion is expected by December, 2015.

Stantec will examine the conditions of the tunnel and explore the viability of several rehabilitation or realignment options.

It also will manage the traffic control, permitting, surveying, hazardous materials handling, and other services related to the design and construction of the new or rehabilitated tunnel.
