1 Bryant Park, The Bank Of America tower

The most amazing job I have had the honor of working on is on the tube right now, I see a lot of friends. This is an amazing green structure, I'm glad I got the call right after it began(thanks Greg). My girl is gonna Tivo it for me too. I hope it's not the last great job I'm on.

The show's called Man Made and it's on the National Geographic Channel

It's airing Friday at 12:00AM (that's Fri. morning if you're like me and need to think about it)
Saturday Nov. 8th at 4:00PM
and next Thursday Nov.13th. at 5:00PM

In the city that never sleeps, one architects dream for a greener future has been realized. The One Bryant Park building in New York City is not only going to be the second tallest building in the city, but is set to be one of the most energy efficient skyscrapers in the world. Richard Cook and his team have taken on an exhilarating challenge to transform the modern approach to green technology. Both groups envisioned breaking new ground in the arena of environmentally conscious skyscrapers, a significant step forward in a city known for massive energy consumption. Join National Geographic as we examine the trials and triumphs of erecting a skyscraper whose blueprints just might map out a new design for our planets future.

So set your Tivo's and DVR's people and get a small look into the craftsmanship of some of the worlds finest construction workers.

Finally a good judgment, right to the point: If you use untrained immigrant workers, you go to jail.

You would think that it would be a score one for the 'good guys', and you would be right, the only bad part is that this story didn't take place in the United states and it took 4 deaths and 3 injuries to bring this to light.

From the far away land of Qatar in the Persian Gulf region, "Jail sentence for supervisor" (7/6/08) - Gulf Times

A Doha court has sentenced a construction site supervisor to two years imprisonment for “negligence that led to an accident” which killed four workers and injured three others last year.

The Syrian and the company that employed him were also fined QR20,000 each. The company was made the second accused in the case.

The court ordered the Syrian, the company and the insurance firm to jointly pay QR150,000 as bloodmoney to the families of three of the victims. The family of the fourth victim had not put up any claim for bloodmoney during the trial and the court said that they can file a claim for it at a later stage in a civil court.

A witness told the court how a crane tilted and fell at a worksite near the West Bay on March 19, 2007, burying four workers and injuring three, two of them critically.
He said the workers were involved in a “complicated operation” at around 6pm when the accident occurred. An engineer representing the company,said the crane was imported from China and was being operated for the first time.

The court found the supervisor guilty of assigning the work to a batch of untrained workers, who were not qualified to do the job.

The judge, Mamon Hamour, said that the company committed a fatal mistake when it assigned such complicated work to an inexperienced supervisor, the first accused in the case.

The victims were identified as three Filipinos aged 20, 40 and 48 and an Indian (25).

Now theres one we can learn on, lets get that blood money and jail time here.

This is a good example of why tower cranes should be thoroughly examined, and more then just once or twice a year. Tower crane examinations require time and contractors are going to have to get used to it. - anonymous crane operator

A story for Scott

This crane operator, who after the deadly crane collapse in New York on May 30th., decided when he climbed his 450ft. tower crane that the first thing he was going to do was to check out the bolting system, what he found was distressing, heres part of the story, from Vertikal.net (6/2/08):

Don't put off till tomorrow, what you should do today

Before going to work at 5:15am I watched the news on the most recent NY crane accident and it was immediately apparent to me that the Slew-ring assembly had failed.

The first thing I did when I got to the top of the 450ft (136m) of 2003, tower crane was check the slew-ring bolts with a 2lb beater using minimum force. There are two rows of bolts, each row having 59.

With the crane balanced off, I started with the top row (slew bearing) and when I struck the third bolt it moved (loose), I continued checking and when I came to the 28th bolt it broke in two! I then went back to the bolt that had movement and decided to remove it for inspection, which revealed a severe crack at the same location as the one that sheared off.

Because of finding two bolts with a similar failure and the likelihood that there could be many more, I immediately put the crane out of operation. The manufacturer has been contacted and we're trying to arrange for a "Factory Engineer" to come out and thoroughly examine ALL the bolts, and if needed oversee the replacement of ALL slew-ring bolts. Which is the only certain solution!

I will admit that if not for this most recent event, I would not have gone through the extra effort/procedure needed to properly inspect a slew-ring. The typical way it's done by operators and inspectors is either just a "visual" while climbing through the slew-ring, or just a tap with a carpenters hammer, relying on your sense of sound to hear a difference between bolts.

The problem with this is that without balancing off the crane to ensure that the load on the bearing is distributed equally, you can't get a true sense that the bolts are equally tightened and torqued to the proper specifications. And that goes for mast bolts too!

Bottom line, it just doesn't tell the whole story, especially considering the potential for loss of life and property damage. These common, time-saving methods are just not enough for what's at risk. Like the old saying goes,” don’t put off till tomorrow, what you should do today"!

This is a good example of why tower cranes should be thoroughly examined, and more then just once or twice a year. Tower crane examinations require time and contractors are going to have to get used to it.

I was recently talking to a third party tower crane Inspector and he boasted that he can inspect a crane in three hours, easy money! In general a good tower crane thorough inspection should take at "least" six to eight hours (depending on configuration). And with all due respect to OSHA and others, "they are the Jack of all trades and master at none", and cannot be expected to have detailed knowledge of tower cranes.
