Vancouver’s Port Mann Tunnel Finally Goes into Service with Help from Moretrench’s Ground Freezing Expertise

By | News | No Comments

Port Mann, Fraser River, Moretrench, Canada

“What they did was really quite unique” City of North Vancouver Mayor Darrell Mussato.

As reported by the Vancouver Sun, Metro Vancouver’s new 3,280-ft long Port Mann Mater main finally went into service in late February after long delays resulting from a mid-bore breakdown of the TBM deep below the riverbed. With all other possible approaches ultimately ruled out due to environmental issues, Moretrench was called in to develop a ground freezing plan to isolate the cutter head from the high surrounding earth and hydrostatic pressures and allow access to the chamber behind the cutter head for repairs.  After just 12 days of freezing, the repairs were able to able to take place and tunneling resumed.

Moretrench, ESOP, Employee Ownership

Recently, Moretrench hosted several representatives from Rutgers University School of Management and Labor Relations who are currently involved in producing a video that will include a section on employee ownership, a particular area of expertise for the University. As Moretrench has been 100% employee owned since 1999, we were more than happy for them to come and see an ESOP company in action. President and CEO Art Corwin, and Staff Engineer Johnna Emanuel participated in the video, contributing their thoughts and experiences from senior management and young engineer perspectives.

Its not just George Washington’s birthday this week… its also National Engineers Week!

By | News | No Comments

georgewashingtonsurveyorYes, there is a connection.  Our nation’s first President was also an engineer in his own right.  In fact, he’s considered America’s first engineer, most notably for his surveying work. National Engineers Week was started in 1951 by the National Society of Professional Engineers to call attention to the contributions to society that engineers make, and this particular week was chosen to encompass his birthday.

During his lifetime, Washington surveyed more than 200 tracts of land totaling more than 60,000 acres. He is credited with drawing more than 100 maps,  including a map of the city of Alexandria, and had a hand in planning the technical layout of Washington D. C.  Engineering as we know it today was still in its infancy. The Industrial revolution was yet to come. Washington’s work was accomplished without benefit of a formal engineering education, making it all the more remarkable.

Today, on his birthday, as we at Moretrench tip our hard hats to American engineers everywhere, we reserve a special nod to George Washington –the man who, in more ways than one, put America on the map.

See you in Orlando!

February 11th is National Inventor’s Day USA

By | News | No Comments

MoretrenchHistoricWellpointHere in the USA, National Inventor’s Day is celebrated annually on the birthday of Thomas Edison, “The Wizard of Menlo Park” and inventor of the first commercially viable light bulb.  And here at Moretrench we have our very own inventor to honor –our founder Thomas Francis Moore.  While Moore’s invention did not impact the world, as Edison’s did, it had a profound effect on the construction industry.

Moore was just 12 years old when Edison made his light bulb breakthrough in 1879. Moore’s own “light bulb” moment came some years later in 1924. By this time, he was manufacturing and leasing conveying excavators for utility trenching from premises in Rockaway, New Jersey.  When one of his machines encountered locally notorious Bull’s liver silts, Moore set about resolving the problem himself, first experimenting in his kitchen sink at home and then field testing.  The result was the first practical wellpoint, which revolutionized the underground construction industry and marked the beginning of Moretrench becoming a nationally recognized leader in geotechnical contracting.  And it all began with one man, a vision, and determination –  and who understood, as Edison once said, that “Genius is 1% inspiration and 99% perspiration”.

NYC’s Second Avenue Subway Now a Reality

By | News | No Comments

NYC, Second Avenue Subway, MoretrenchAlmost 100 years in the making, New York’s Second Avenue Subway opened on New Year’s Eve.

Moretrench is proud to have played a part in the first phase of this long anticipated extension, undertaking a number of diverse contracts.  These include dewatering  and groundwater treatment  for excavation of the 800-ft-long launch box;  ground freezing to overcome mixed faced conditions along the twin tunnel alignment;  jet grouting to close windows at the intersections of secant pile and slurry wall excavation support;  rock grouting to stabilize shallow, fractured rock cover above a hard rock TBM receiving shaft; and compensation grouting to stabilize the rubble foundations of existing multi-story buildings in concert with excavation for new deep sewers as part of the station construction.

The newly opened section runs for 1.8 miles and is anticipated to carry approximately 200,000 passengers daily.  When completed the Second Avenue line will run 8.5 miles along Manhattan’s East Side.

Moretrench’s Rapid Response Capability Earns Delaware River Bridge Repair Contract

By | News | No Comments

Delaware River Bridge, Emergency Repair, Micropiles, Temporary Support System
The Delaware River Bridge, which carries 42,000 vehicles daily between the New Jersey and Pennsylvania turnpikes, has been closed since January 20th when a significant crack in a truss member beneath the deck was discovered during final painting inspection. The bridge was immediately shut down, and Moretrench was one of several geotechnical contactors contacted the next day by the New Jersey Turnpike Authority to provide the micropile foundation systems proposed for support of eight temporary steel jacking towers that will stabilize the bridge during repairs.

“We demonstrated that we had the resources to do the work and were able to mobilize immediately,” said Project Manager Yaser Taheri, P.E.  “We were awarded the job on the 23rd and were on site the next day.”

The fast-track operation calls for six, high capacity micropiles installed at each jacking tower location to depths of between 120 and 140 feet.  The towers will tie directly into the foundation system. Moretrench has mobilized three drill rigs and five crews and has been working around the clock since Day 1.  “We are installing micropiles at several locations simultaneously,” said Taheri. “Despite difficult drilling through variable geology, we are comfortably within schedule.”
