Big Dig - One of Engineering's Greatest Mistakes?

Enggirl1 writes "Design News discusses Boston's Big Dig and begs the question - is it one of engineering's greatest failures? The article reveals that forums and blogs are popping up all over the Internet as vehicles for engineers and contractors to discuss, under the guise of anonymity, their skepticism, thoughts and reactions to one of the biggest infrastructure failures in the news today." From the article: "One blogger, whose profile notes that he is an ICC Reinforced Concrete Special Inspector and an ICC Pre-stressed Concrete Special Inspector, among other specialties, says he has nearly 20 years of experience performing both placement and post-placement inspections of rebar, post-tensioning systems, concrete, masonry, etc. He says if structural engineers who specify epoxy for dowels and the like believe that the work is being done correctly then they live in a world unfamiliar to him."

Inspecting your own work

[xXBondsXx]

One of the main problems the team had on the Boston Dig project was that some genius decided to hire the same contractors for both the construction and the inspection of the tunnel. Consequently, the inspector gets put in an awkward position, for if he finds anything wrong, he can either...

A) blow the whistle, cost the company extra money, and then get fired for "undisclosed reasons"
B) look the other way like a good little puppet of the company, get paid, and never have to really deal with the consequences face to face

Seriously, whoever thought that it was a good idea to hire the same company for both construction and inspection is a little naive. Would you let McDonald's do the FDA testing on their own food?

Re:Cheap, Illegal Labor != Good Quality

On any project that involves public safety, an English-speaking, literate, educated worker is much more preferable than a non-English-speaking, illiterate, uneducated worker.

You create a false dichotomy, because there are many American construction workers who can't read the instructions for assembly.
Quality isn't an illegal immigration issue. Doesn't matter if it's a Mexican illegal or American just off the farm, if they don't have the skills its the problem with the construction company. They didn't do a sufficient job of ensuring their laborers had the skills and ensure the quality of work. Illegal immigrants are just a pool of labor, the impact they have is on the value of labor in certain industries. Those who make hiring decisions are the ones responsible for sacrificing service and quality for price.

Hardly the biggest mistake - an amazing project

As Yoda might have said, "Break me a fscking give!" --

The big dig constitutes several of the most ambitious and complex infrastructure projects imaginable. They had to freeze the ground in the back bay by piping supercooled fluid through it while digging in that part. They have completely re-routed one of the largest transportation networks in the world without closing the old one (other than a few hours at a time at night or weekends). As the last phases are completed -- the cleanup of the old site -- Boston becomes one of the most beautiful cities in the world. What used to be a hideous elevated six lane highway becomes a walking park with small shops, museums, and playgrounds that connects the entire downtown area from Haymarket and Fanuel Hall past the New England Aquarium, all the way to South Station.

It was typically corrupt on a scale only an eastern (or European) city could manage, it was over budget and time on an epic scale -- but did anyone really expect otherwise? Someone really screwed up on these bolts. They'll get fixed, the lawsuits will settle, and in the meant time this project will be the pride of Boston for many years to come.
