Using their heads to move a pile of rubble
Filed under: Productivity — Tags: — kaegw

Debby and I are in India visiting two of our kids who have been wandering around here for the last seven months. It’s a fascinating culture. I tend to pay attention to things I know, so I’ve been watching the construction business here.

We were staying at a little cheap hotel and I could see a construction project out our window. A large pile of construction rubble (broken concrete, rocks, etc.) was within view. Since labor is cheap in India, their method to move the pile involved no equipment more complicated than a shovel.

Several women, wearing the traditional saris, made the process fascinating to me. Each woman walked quite erectly with a wide wicker basket balanced on her head. The basket seemed about 3′ wide and less than a foot deep. Men standing at the rubble pile loaded this basket and helped her lift it onto her head (the lifting seemed to take two people but the carrying was a solo activity).

The women kept making the trip back to the pile with empty baskets on their heads, then walked away with full ones. I watched for a while, intrigued by a very different method and set of relationships than I’ve ever seen on the job. I wondered a few things.

How do the women get treated on the jobsite? Do the men harrass them? Flirt with them? Ignore them? Does anyone go through an economic analysis of using labor vs equipment? What happens here with work site injuries? Do more primitive work methods bring less worker satisfaction since less gets done or is the level of worker satisfaction independent of technology and production?

The only thing I know for sure is that when we got back from a day of touring Mumbai, the pile of rubble was completely moved. The next day they were placing concrete for a 4th floor slab and the woman material movers were carrying concrete in baskets above their heads.

Some cool buildings
Filed under: Design — Tags: — kaegw

I came across some photos of buildings in Japan that astound me. Can you imagine being the Construction Supervisor on one of these projects? What must the prints have looked like? We’ve all built projects where the Owner just keeps changing the course of the project, I wonder if that’s how these buildings ended up the way they did.

Update on NYC crane rules
Filed under: safety — Tags: , — kaegw

With another crane collapse last weekend and over 26 workers dead in the past year, NYC continues to struggle with how to handle their construction boom more safely. ENR.com announced today that NYC will now require safety courses for all those working on cranes and a new accident tracking program. The 30 hour course will probably raise awareness in a few workers, but most of us that work around cranes understandthe dangers.

Why do you think so many accidents happen on construction sites? I know inexperience plays a role in many accidents, but I believe our own personal drive for efficiency and production often overrides our judgement. Too many times the machisimo of getting it done quickly controls our actions more than the side of our nature that acts cautiously. So I’m placing the responsibility for many accidents on the dedicated worker who’s pushing for efficiency. What do you think?

Here's a website where you don't want your project photo

Named Drunk Builders and Mad Architects, this collection of photos shows inspired stupidity with some great photos. Here are a few examples:

There are lots more examples of what not to do. It’s a great business, isn’t it?

Why are the cranes falling in NYC?
Filed under: Construction,safety — Tags: — kaegw

Have you ever been involved in a crane accident? It’s brutal. I’ve had two crane collapses on my jobsites. In the first, we had a little 50 ton hydraulic crane with a young operator. He just miscalculated the load and laid it down, fortunately with no injuries.

On the Hershey PA High School project, though, the steel erector’s crane had the main cable snap. Joe DiFava, a friend of mine who pays incredible attention to his environment, saw the boom falling towards him and shoved a co-worker out of the way, probably saving his life. The end of the boom just hit Joe’s hardhat, shooting him out of the way like a watermellon seed. The fellow who got shoved out of the way had the end of the boom land on his boot, losing several toes.

As you’ve probably read, another crane fell in NYC, with the boom and cab crashing into an apartment building below. This was the second crane collapse in three months, killing two construction workers. Now 26 construction workers have died on jobsites in NYC in the past year. The mayor responded by hiring 20 more engineers to inspect all the cranes working in the city. Do you think this was a reasonable response?
