Efficiency Drives the Dream
Filed under: General Technical Skills — Tags: — nedpelger

I’m reading My Bondage and My Freedom, a book written by brilliant former slave Frederick Douglass. Everyone should read this book to gain a sense of the realities of slavery and the African-American experience. As a newly escaped slave, Douglass writes about the efficiency he sees in New Bedford, MA compared to the slavery system he was born into:

My first afternoon, on reaching New Bedford, was spent in visiting the wharves and viewing the shipping. The sight of the broad brim and the plain, Quaker dress, which met me at every turn, greatly increased my sense of freedom and security. “I am among the Quakers,” thought I, “and am safe.” Lying at the wharves and riding in the stream, were full-rigged ships of finest model, ready to start on whaling voyages. Upon the right and the left, I was walled in by large granite-fronted warehouses, crowded with the good things of this world. On the wharves, I saw industry without bustle, labor without noise, and heavy toil without the whip. There was no loud singing, as in southern ports, where ships are loading or unloading—no loud cursing or[269] swearing—but everything went on as smoothly as the works of a well adjusted machine. How different was all this from the nosily fierce and clumsily absurd manner of labor-life in Baltimore and St. Michael’s! One of the first incidents which illustrated the superior mental character of northern labor over that of the south, was the manner of unloading a ship’s cargo of oil. In a southern port, twenty or thirty hands would have been employed to do what five or six did here, with the aid of a single ox attached to the end of a fall. Main strength, unassisted by skill, is slavery’s method of labor. An old ox, worth eighty dollars, was doing, in New Bedford, what would have required fifteen thousand dollars worth of human bones and muscles to have performed in a southern port. I found that everything was done here with a scrupulous regard to economy, both in regard to men and things, time and strength. The maid servant, instead of spending at least a tenth part of her time in bringing and carrying water, as in Baltimore, had the pump at her elbow. The wood was dry, and snugly piled away for winter. Woodhouses, in-door pumps, sinks, drains, self-shutting gates, washing machines, pounding barrels, were all new things, and told me that I was among a thoughtful and sensible people. To the ship-repairing dock I went, and saw the same wise prudence. The carpenters struck where they aimed, and the calkers wasted no blows in idle flourishes of the mallet. I learned that men went from New Bedford to Baltimore, and bought old ships, and brought them here to repair, and made them better and more valuable than they ever were before. Men talked here of going whaling on a four years’ voyage with more coolness than sailors where I came from talked of going a four months’ voyage.

Those who excel in construction tend to see the efficiencies that Douglass discusses. He writes about the use of the block and fall (pulleys) to multiply the power of labor. We should all understand how basic machines work and the simple science behind them. My son sent me this video with an amazingly simple and helpful explanation of a differential gear. I love seeing complexity explained with clarity.

Efficiency really does drive the dream. Strive to understand the physical word that we inhabit and build.

Female Construction Supervisors Out-Earn Men
Filed under: Construction — Tags: — nedpelger

In the overall US Economy, a Bureau of Labor Statistics reports that women earn $0.81 compared to $1.00 for men. However, there are some exceptions. A recent Forbes article titled 15 Jobs Where Women Earn More than Men listed Construction Supervisor. Apparently 97% of Construction Supervisors are men, but those few women make more.

The article states, “Researchers have found that both sexes fare better when they are in the minority,” says Caren Goldberg, a management professor at American University’s business school in Washington, D.C. “Women who choose male-dominated jobs are likely perceived as “atypical” or less consistent with the stereotypes associated with women, which are also associated with lower-paying jobs.”

With the relatively high wages and the enjoyment of building things in the construction industry, I’ve always wondered why more woman don’t participate. I wonder if Port-A-Potties have anything to do with it?

An Owner’s Owner Manual: How to Understand Your Building Construction Owner
Filed under: People Skills — Tags: — nedpelger

My brother Jim was running Pelger Electric, a small electrical contracting firm started by our Dad and Grandfather in 1946. Jim and I were discussing Owners and he said, “You know, you should just let chislers work with chiselers.” I remember thinking about the various rotten Owners I’ve done projects for and how the ones I knew would be chiselers certainly ended up acting the part. The projects we did for them were torture and rarely made enough money to be worth doing.

At the time Jim and I spoke, I was running a 75 person general contracting firm and felt I needed to take whatever work we could snag to keep all the bodies busy. When I went on my own, I was able to more carefully choose my Owners. Life improves dramatically when not working for chislers (Owners who aren’t happy unless you’ve been financially beaten up). I’ve often turned down offers for projects when I determined the Owner didn’t seem likely to have integrity. I have never regretted making one of those calls.

On the other hand, I’ve almost always regretted working for chiseler Owners. I generally had a gut feeling going into the project that this guy was going to screw me. By the end of the project, sure enough, I had been screwed. As my old boss Ed Abel said, “Never get in a pissing contest with a skunk.” In this instance, that meant that the chiseler Owner would be willing to act worse than I would and would accomplish his shenanigans.

We are starting to build 84 apartment units today and the Owner on the project got me thinking about this concept. He’s the opposite of a chiseler, he’s an honorable man who has succeeded in business by integrity and amazing competence. Dereck Hench, the Construction Supervisor I work with, told me an interesting observation about this Owner. After meeting to review lots of details, the Owner asked Dereck a question about hunting in Montana. That led to a discussion that went on for about an hour. The Owner learned about Dereck’s family, his background and many of the people they both knew. He didn’t do it to be nosy or to check him out, but he genuinely cared about who he was to be working with.

Dereck told me later, “I never had an Owner take that much of an interest in me.” By his tone I knew he appreciated the time and the attitude. This Owner not only learned more about his Construction Supervisor, he also created in Dereck an ally to protect his interests above and beyond.

Remember, just because the construction industry is struggling through some hard times now, this truth about Owners doesn’t change. Working with a chiseler Owner will generally be worse than having no work.

As you strive to understand the Owner on your project (or perhaps your boss) you can gain some useful insights with my phone app Strategy of Personality Profiles for Better Communication. This recently posted review was encouraging.

“Very Nice! Good, Quick, and knowledgeable – I used to describe my personality. And plugged wife’s, friends, and work colleagues. Right on target for all four. Can’t wait to use it more. Would be nice to print/email results (without copy and paste).” – User review from BlackBerry App World

So You Think You’ve Got a Big Tool?
Filed under: Construction — Tags: — nedpelger

We love our tools in construction. We always want to have the right tool for the job, knowing how much better everything goes. When it comes to heavy equipment, the bigger the more impressive.

Lex sent me this photo of a tunnel drilling rig, which staggers the imagination.

Look at that man crawling on the rocks, he appears to be an action figure. They are completing the NEAT Gotthard Base Tunnel that crosses the Alps in Switzerland. The huge construction project should complete in May 2016 and will cut the travel time dramatically from Zurich to Milan. The sketch below fascinates me as well.

Understanding Radiation Risks
Filed under: Energy — Tags: — nedpelger

I love to see a well conceived chart that conveys complex information in an intuitive way. Having attended a one day seminar by Edward Tufte, Presenting Data and Information, I learned to see the beauty of complexity shown simply. I also learned to spot how many charts show information incorrectly, out of scale or just wrong. Prof Tufte still travels the country teaching those seminars and I encourage you to try to attend one.

My friend Neal Leininger sent me a note, “With all the news outlets scrambling to fan the flames of panic: Here are some FACTS.” The chart about radiation levels shown below was linked.

You can quickly consult this chart (click on it to enlarge or follow the link) and understand the relative danger levels of radiation. Having access to this kind of knowledge makes us more effective. I try to present construction knowledge in ways that are also clear and intuitive. Sometimes I succeed.

Be Ye Skeptical
Filed under: People Skills — Tags: — nedpelger

Surely You’re Joking, Mr Feynman is one of my favorite books. Bruce Jackson, a brilliant friend who recently died in a plane crash, recommended it to me. In one wonderful scene, Dick Feynman gives a short talk at the Princeton Institute for Advanced Studies. He’s a young guy (in his 20s), full of good and bad ideas. As he begins to talk, he realizes Albert Einstein and Niels Bohr are both in the audience, along with several other science giants.

Feynman was taught by his father, as I was taught by mine, to not respect the rank or the uniform. Struggle to find what’s true, while being skeptical of those with rank and more open to those without. As these science legends made suggestions about Feynman’s talk, he argued back with vigor. He cared more about the idea than the personage.

He speaks in the video about how hard it is to know something. He explains how careful you have to be to know something in science. So many folks act scientific, act like what they are saying is true and scientific. So many times it’s just propaganda or wishful thinking.

httpv://www.youtube.com/watch?v=Bgaw9qe7DEE

This long video was a pleasure for me to watch. Feynman discusses his time working in Los Alamos on the Manhattan project in the early 1940s and the jubilation, then depression after the atomic bombs were dropped. He’d watch men building a bridge and think, “How foolish, don’t they know that this will all be destroyed?” He assumed that nuclear war would closely follow the end of WWII. I’m grateful he was wrong.

If you want to stretch your world view, to learn better how to learn, consider watching this video or reading more Feynman. He’s a Curious Character who will make you laugh out loud sometimes and think deeply others.

Construction Remains a Drag
Filed under: Industry outlook — Tags: — nedpelger

From Vanguard’s Economic Week in Review: Fed’s outlook brighter but stocks shaky:

Gradual improvements in the labor market helped lift the Federal Reserve’s outlook for economic recovery, though construction remains a drag. Food and energy prices jumped, with core inflation still modest. But investors were perhaps more distracted by declines in stock prices during the week in the wake of Japan’s earthquake-tsunami-nuclear woes.

I just returned from a Lancaster County Mud Sale, huge community auctions run by Amish folks to benefit volunteer fire companies. I spoke with an old friend. His carpentry and home renovation business has no work currently. He said, “Last year was bad, but so far this year, I haven’t had any work at all.” He’s a competent, honest contractor who does excellent work. He just can’t find any.

This wonderful business we’ve chosen—to design and construct buildings and other structures, seems to be navigating the most challenging times in the past 50 years. What words of wisdom can I offer?

What doesn’t kill me makes me stronger.

Try to use these challenging times to better understand yourself and this business. Try to position yourself in a place to win. Remember the fundamental rule of success:

Successful people do the things unsuccessful people don’t want to do and won’t do.

Some Useful Tech Advice
Filed under: Phone Apps for Construction — Tags: — nedpelger

My son Lex wrote a helpful post listing two important ways to protect your tech data.

  1. Have all your important files backed up automatically to the cloud with minimal effort and low cost.
  2. Add a phone finder app to your smart phone that helps you foil thieves and your own stupidity.

You can get to the post either by following this link or clicking on the Phone Apps Blog icon at the top of the ConstructionKnowledge.net site. Lex lives in Belgium these days, but his writing hasn’t seemed to pick-up an accent yet.

Fission Primer and the Japanese Crisis
Filed under: Energy — Tags: — nedpelger

The Fukushima I Nuclear Power Plant experienced the earthquakes and flooding of the past few days. The nuclear reactors shut down automatically after the earthquake, but the subsequent flooding and loss of power via emergency generator flooding has caused loss of control of the reactors. The sketch below provides a bit of insight into the Fukushima reactors:

As I tried to understand the crisis, here are a few things I learned.

  1. Are the various explosions nuclear explosions? No, the exposed (due to lack of cooling water) metal fuel rods react with the steam to produce hydrogen. The reactors are designed for that hydrogen to burn off prior to explosive levels being reached, but the lack of electricity probably kept that system from functioning. Therefore, the hydrogen concentration increased then exploded (think Hindenburg).
  2. Did those explosions crack the containment vessels? It appears the containment vessels (prestressed concrete several feet thick with a steel core) has not been damaged by the hydrogen explosion. The upper building shell (mainly in place to keep weather off the reactor) was damaged.
  3. Why is Reactor #3 the most critical? There are 6 reactors, but only #3 uses plutonium as a fuel. The byproducts of the plutonium reactor are much more carcinogenic than from the other five.
  4. How much radiation has actually been released? The levels at the plant were around 751 microsieverts, a dosage similar to a stomach x-ray. A fatal dose of radiation would be more than 7 million microsieverts. The Japanese authorities are instructing nearby residents to stay indoors and are distributing potassium iodine pills to prevent radiation from building up in the thyroid (the most dangerous aspect of nuclear fallout). One resident commented, “My house was washed away by the tsunami, now the government tells me to stay indoors.”
  5. What is a meltdown? Actually, the term meltdown isn’t used in industry codes or documentation. The media uses that term, but it doesn’t have a precise industry definition. Generally, though, a meltdown would be the nuclear fuel rods creating some much heat as to melt through the steel and concrete core liner.
  6. Will the containment structures be breached (meltdown)? Each day seems to bring some good news and some bad news. As of today, it’s possible each of the 6 reactors will be adequately cooled with ocean water or their normal cooling water and prevent further damage. It’s also possible (though I think much less likely) that the cooling systems will fail and a meltdown will occur.

Update on March 19, 2011: It appears Reactors #1, 2 and 3 are currently stable (though with damaged cores), with sea water being pumped into them via fire hoses. The helicopters dropping water and water cannons spraying flumes were creative but unsuccessful efforts. Reactor #4 seems to be most at risk, with little data available about the current condition. The life threatening work performed by the plant workers inspires me. What great honor and courage!

I’ll update as seems appropriate.

Courage vs Prudence
Filed under: People Skills — Tags: — nedpelger

Take 25 seconds to watch this gorgeous natural natural rock water slide in Brazil.

httpv://www.youtube.com/watch?v=ldZZPFssHKI

Certainly the slider shows some courage, slipping into the unknown experience. A gash and some stitches or a cracked head could have happened, though they didn’t. I love the visual of the kid sliding with the audio of the circumspect.

So where do you stand on the courage vs prudence issue?

Yesterday, a potential client drove with me to an old apartment building. The real estate agent didn’t have the key in the key box, so there appeared no way into the building. My client managed to jump up on an electrical meterbase, then reach for the tip of a descending steel fire escape that no longer descended, then pulled himself up and shoved a door open. Then he said to me, “You probably can’t get up this way, I’ll see if I can get another door open”.

Though he was a bit younger than me, the “You probably can’t do this” statement sufficiently motivated me to scurry right up that sucker as well. Perhaps not too prudent, but it got me thinking about that dance between courage and prudence.

I’ve long abhorred the concept of living in fear of any risky consequence. The “Sleepwalking through life to get to death safely” seems such a waste of our adventure here on Earth. Yet, as my father still reminds me, “You don’t need to play in traffic, either.”

I’ve found a helpful trick: try to never let fear dictate your actions. Don’t be afraid to be courageous. Don’t be afraid to be prudent. Actively choose your course, not from fear, but from experience, wisdom and the knowledge that none of us get out of here alive.
