Carpenters Working On Concrete Forms (Gallery)

Posted on by Nick Roberts

The images in this gallery are of the Carpenters working on concrete forms on the Indiana Approach for the Downtown Span of the Ohio River Bridges Project. The carpenters are installing cooling lines that will carry water from the river through the concrete after it sets in order to keep it from overheating as it cures. Concrete cures due to a catalytic reaction between the cement and other chemicals in the mixture. If the concrete overheats during the curing process it may not be strong enough to do it’s job which is why it is crucial that some way to transfer the heat from curing out of the mass of material.

I processed the full color versions of these images using Adobe Camera Raw using a series of steps that i learned from reading Scot Kelby’s book on using Photoshop CS5. Rather than use my usual method of creating HDR images from three frame bracket sets I instead decided to work with the “normal” exposure alone and see what I could accomplish using ACR.

After creating the color images I decided to use [thirstylink linkid=”13827″ linktext=”Topaz” class=”thirstylink” title=”Topaz”] B&W Effects to produce versions that have an antique feel to them. I used various adjustments to create my own preset that desaturated the colors and added a vignette of faded edges. I then applied a border from Topaz that I thought fit the idea I had for the final images. I saved this preset to use later on other images that may benefit from similar treatment.

One of the wonderful things about photographing construction work is seeing Journeyman of the many Skilled Trades that are teaching Apprentices the skills they need to be qualified trades people. The history of the Skilled Trades is filled with the accumulated knowledge that generations of earlier tradespeople have shared with their Apprentices. By sharing their experience with an Apprentice a Journeyman provides continuity and pride in the ability to master a trade.

An Apprentice faces unknown tasks that, unless they have been properly trained, could result in an inferior result. The Journeyman doesn’t do the task but instead instructs and verifies that the Apprentice learns the proper tools and procedures to follow when they have earned their own Journeyman’s card. In time today’s Apprentice becomes experienced enough to qualify for a Journeyman’s Card and completes the cycle by taking an Apprentice of their own to mentor and share the skills of the trade with.

Watching this young woman learn the proper way to complete the task of installing bridge decking is one of the great things being a construction photographer. Photographing them working together allowed me to see the way skilled Journeymen can make a difference in someone else’s life. As they joked and kidded one another they also were developing a bond that will last a lifetime for both of them. The Apprentice learned how to secure decking in a way that insured that it was properly installed and the Journeyman had to feel a sense of pride in sharing his skills with her.

As with the Ironworker’s trade the Carpenter’s Union also trains new Carpenters through the Apprenticeship model. The process is the same though; a Journeyman Carpenter trains and instructs the Apprentice in the skills he or she will need to earn their own Journeyman’s card and join the ranks of Journeyman Carpenters going back generations in time.

All four of the images in this post are three frame bracket sets of +2, 0 and -2 EV exposures that have been merged in NIK HDR Efex Pro 2 software and finished with Aperture 3.All required strong anti-ghosting application due to the movement of the men and women as they went about their tasks. The anti-ghosting feature in NIK HDR EFex Pro 2 is by far the best I have used and remains the main reason I prefer it to any of the other HDR apps on the market today.

The Surveyor in this image is William Moylan. I met William last year while he was surveying the placement of a caisson in pier 6 during it’s installation. I shot some photos of him that morning and ultimately chose one for a blog post. William saw the photo and thanked me for sharing it with the world. At the time he said to me that no one ever takes pictures of the surveyor. Later as we got to know each other he told me that his Mom in Ireland was able to see what he did for a living and the job he was working on because of that photo.

I was waiting for the crew boat yesterday when I saw William and a Carpenter working together. I liked the angle that I had and started shooting them discussing the task they were both working on. In this image they are making plans for William to ride up in the aerial lift to check the platform being placed for a hammerhead form that the carpenters are building on pier 8.

In this image you can see the floor of the hammerhead form that William and the Carpenter are leveling. William has climbed out onto the form floor with his measuring equipment and the Carpenter is moving into place underneath the form to make leveling adjustments.

Both of these images are three frame bracket sets of +2, 0 and -2 EV exposures that have been merged in NIK HDR Efex Pro 2 and finished in Aperture 3. For the top image I had to sue 100% anti-ghosting to eliminate the ghosting of the figures. In the second image I was able to get by with only 60% anti-ghosting. My advice regarding anti-ghosting is to strive for the lowest amount you can use in order to minimize halos and still achieve a reasonable final result.

HDR Construction Images of a Morning in November 2013

Today’s post is rather long on images yet short on words. I decided that what I wanted to show my readers was a series of several HDR construction images from a morning in November 2013. I thought sharing these HDR images from a single morning shoot would help my readers see how busy things are on the Ohio River Bridges Project.

I am always amazed at the skill and expertise that is required to do the work of Heavy Highway and Bridge Construction. Ironworkers, Carpenters and Operating Engineers must choreograph so many moves into placing the pieces of a single pier. The skill and commitment  to safety that they use to get the massive components in place is a sign of their professionalism and dedication to their respective trades. Any miscalculation when handling these pieces could result in slowing or stopping construction or even worse the very real possibility of the loss of someone’s life. For that reason the attention paid to properly performing each element in the process is paramount to safely accomplishing the task at hand.

I hope these HDR construction images help reveal the size and scope of the Ohio River Bridges Project as well as the my admiration for the skilled tradesmen and tradeswomen who perform these critical tasks. I also hope that the next time you see a construction site or meet a construction worker you will see their contribution to our way of life and the valuable part they play in building the world. Maybe you’ll even have a little more understanding of the important role that organized labor plays in providing skilled professionals that construct safe and dependable infrastructure for our world.

One final note about these images. All of the images in this post were created from three exposure bracket sets of +2, 0 and -2 EV exposures. They were merged in NIK HDR Efex Pro 2 and finished in Aperture 3. I use NIK HDR Efex Pro 2 because it does the best job I have found of reducing, and in most cases eliminating, ghosting when working with active subjects such as the men and women in these images. I finish the merged images in Aperture 3 because it allows me to control all the other variables such as color, contrast, sharpening etc in a non-destructive workflow.

HDR Photos of Progress on the Ohio River Bridge North Tower

Going Up

The Ironworkers and Carpenters have been very busy over the winter and the North Tower of the Downtown Span is progressing well. In this first image you can see the tower base as it stands today. The Ironworkers are tying the rebar for the next section and as soon as that is done the Carpenters will form that section for the next concrete pour.

I regret that I was under the weather for the first two months of this year and unable to get out to the Ohio River Bridges project very often. In looking back at the images from the end of 2013 I can see that there has been a great deal of progress. I’m back on the job now and will be posting on a regular basis as I did throughout the end of summer and into fall.

All of these images today are HDR images processed in NIK HDR Efex Pro 2 and Aperture 3. As is my standard practice I shot everything handheld in three frame bracket sets of +2, 0 and -2 EV exposures. I applied 60% anti-ghosting during the merging of these three exposures and used the Balanced Preset as my starting point. After merging them and applying the preset I went back into the tone mapping settings and changed the Detail slider to Accentuated and the Drama slider to Deep. That is all I did in NIK HDR Efex Pro 2 before returning the merged file to Aperture 3 where I adjusted the color channels, sharpening, contrast and applied a small vignette.

In this image the Ironworkers are working with the crane Operator to lift more materials onto the tower scaffolding. They have to communicate with the Crane Operator using hand signals and radios to safely manage material transfers. I am always amazed at the skill of these crane operators to place everything from a small bundle of steel reinforcing to massive concrete forms on the job with pinpoint accuracy.

In this HDR image the concrete form is being removed from the angled surface of the eastern side of the eastern pier of the North Tower. The carpenters have unbolted it and rigged it for the crane Operator to lift it and transfer it to a waiting barge until it is needed again. Seeing the Carpenters alongside these forms gives scale to their size. Once again the Crane Operator and the Carpenters are working through radio and hand signals to safely move this massive piece of concrete form.

For this HDR image I chose to shoot the removal of the concrete form in a vertical format to better capture the cranes and the upward momentum that the project exudes as it progresses.

This HDR image shows both bases for the North Towers of the Ohio River Bridges Project Downtown Span. The progress that is being made really comes out in this HDR photo. The concrete forms have been removed from the base of the western side of the towers and scaffolding is surrounding the transition point as the base morphs into it final cylindrical shape which will be approximately 150 feet in the air when it is completed.

This HDR image shows a cooling manifold being lifted into place. It is used to distribute cooling water through the concrete as it cures. When concrete cures there is a lot of heat inside it; this is due to the catalytic reaction of the materials that are used to make concrete. Without cooling this reaction would cause the concrete to overheat and lose it’s strength. The cooling process goes on until sensors built into the structure provide the information to show that it is safe to stop cooling the concrete and allow it to finish curing.

I’m really glad to get back to shooting the Ohio River Bridges Project and posting my work again. I hope that small hiccup at the beginning of the year won’t be repeated and I can complete my project of documenting the Ohio River Bridges Project and the men and women who are doing it.
