Construxction of Montreal's New Champlain Bridge
[the middle lanes of traffic are dedicated to public transport vehicles including a light metro line.]
Andre MylocoposAndre and 111 others joined Manitowoc Crane Enthusiasts within the last two weeks. Give them a warm welcome into your community! Clarification: the black boom one is a 900 US ton and the blue boom is a 1433 US ton unit, one of only 3 built.

A challenging 42-month timeline has been established for construction of the new bridge....To meet the challenging timeline, the decision was made to maximize the prefabrication of concrete and steel parts and assemble some on site and some off-site. For this purpose, a total of five jetties (three for the new Champlain Bridge and two for the new Île-des-Sœurs bridge) will be created during the preparatory phase of work (June to November 2015). They will also allow for dry construction of various parts of the bridge and serve as docks for mooring the many vessels to be used on the Saint Lawrence River. [Engineering]
“That there are so many problems and that we spend so much time at the site repairing all this, no, it’s really not normal,” an engineer involved in the site, who requested anonymity, was quoted as saying.Another article [GlobalNews-defects] mentioned bad parts from Spain. I confirmed that Tecade is in Span at their headquarters and Seville.
The main problems detected were in six areas:
– HOLES BADLY MADE AND MISALIGNED: Some holes are not well positioned in parts that need to be bolted to each other, thus preventing their alignment. Other holes are poorly made and required new drilling.
– POROUS STEEL: Some steel plates from Tecade used in the ‘caissons’ (watertight retaining structures used to work on the foundations of the bridge pier) show signs of porosity. The metal contains bubbles that can compromise its strength. – CRACKED STEEL: They ‘discovered cracks that cross the entire plate in over a dozen locations next to the connection holes’, an engineer report from GHD said, who inspected the repairs made to the Tecade caissons.
– DEFECTIVE SCREWS AND BOLTS: Complete boxes of bolts and nuts arrived from Spain with important defects. Several did not have the dimensions required on the plans.
– INCOMPLETE WELDS: Teams of workers had to repair many defects in metal work especially incomplete welds.
– MISSING CONCRETE: The pillars of the bridge are composed of huge blocks. One of them was blown up because of a defect in the concrete used. The workers also had to add concrete in the spacer, a huge piece that must link the two pillars of the main pylon. The piece arrived with holes revealing the metal frame.
What is it about Canadian bridge building that they can't get something as fundamental as bolt size correct? The Nipigon River Bridge used bolts that were too long.
There are articles (Feb 23, April 13, June 27) about meeting the December 21, 2018 deadline for opening the bridge. The date had already been moved from Dec 1 to Dec 21. And officials have reserved $10 million to keep the old bridge open until June 2019. The consortium was saying that they will meet the deadline. But after a 9-day strike by the crane operators, they are now saying they are striving to meet the deadline.The strike was by thousands of operators across Quebec, and it was considered illegal. [GlobalNews-strike]
"Officials heading the consortium, led by SNC-Lavalin, insist they’re still striving to meet the deadline, but admit they do need to reassess....The consortium will face a fine of $100,000/day for the first seven days the bridge is late, and $400,000/day after the first week." [June 27] Maybe they should charge the crane union for 9 days of delay.
I lost track of how many workers have been added to the project to try to meet the deadline. And that was before the 9-day strike.
Alex Caron posted three photos with the comment: "Construction of new Champlain bridge in Montreal. Manitowocs as far as the eye can see!! Some 16000 , MLC650's, and Grove's visible in the picture."
Charles Klinger Great design on the peirs !
Donnavan Kelley They look cool! But there a pain to build!
Ben StalveyBen and 4 others manage the membership, moderators, settings, and posts for Manitowoc Crane Enthusiasts. Great shots several MLC 650 on this job.
Jim Browne And 2 of the only 4 2250 Ringer's ever built. I think a 900 ton and 1433 ton version?
[Crane rental alone would be a significant expense.]

M1200 ringer with boom 72. Champlain Bridge Project in Montreal.
Maxime Launier 9474-A 278’ of boom. 1,553,800lbs at 75ft but more impressive is 150,800lbs at 275’ radius. Keep in mind this is a barge chart and the crane is not max counterweight.Francis Letecia Reyna Pawelek Might need it in Corpus Christi harbor bridge soon
Gonna be 178 feet hi I believe
[The block alone being twice as tall as the men puts in perspective how big this thing is.]

[It has a MLC650 label on it.]
Anthony Lucibello posted two photos.
Maxime Launier This is from the Champlain Bridge Project in Montreal. This 650 has been sold to a company in the US which will pick it up shortly.
Anthony Lucibello Maxime Launier the other crane is a 650 as well right ?
Maxime Launier There are a couple of cranes left. There is another 650 with a luffer on the south shore.
[This link accesses a professional description of the project as an alternative to my babblings. They had to design for an ice load of 3 feet and do wind-tunnel studies of the cables that included ice in the wind. They used stainless steel for the rebar to meet the design goal of 125 years in a harsh climate. Of note is that the completion date is June 2019. I wonder when they gave up claiming Dec 2018. The cost is listed as $2.4b.]
[Note that with no load the counterweight tray has a small radius.]

Dennis DeBruler It appears that they did not meet the Dec 2018 deadline that they were still promising last Summer to achieve. https://industrialscenery.blogspot.com/.../champlain...
