The opening image is a shot of Monique Jones in the cab of here Front End Loader while working on the Ohio River Bridges Project. “Moe”, as she is known by the crew members at the Kentucky Approach of the Ohio River Bridges Project, is seldom without her wonderful smile. She is on the go all day long moving everything from rock for the project to large containers of parts.I don’t think I’ve ever seen her when she wasn’t sitting up there in her “office” smiling.

The photo above is of Todd Blankenship one of the many Crane Operators on the Ohio River Bridges Project. It seems that nearly every photo I shoot of crane operators is from this vantage point. I think it is appropriate since their work has them looking high into the sky over the job.When guys like Todd have a load hanging from the crane they are constantly looking up to see the signals from the people they are working with. The job of a Crane Operator is one that carries immense responsibility; any mistake by them could cause a catastrophic situation if the load or the crane itself were to topple.

In this photo Slade Rock and Jimbo Clark are working together to build a rebar structure for one of the many pier caps that support the roadway. In the background you can see a column with a concrete cap sitting on it. The structure Slade and Jimbo are working on will be lifted up and placed inside the concrete forms on another column to strengthen the concrete cap. Jimbo is a Journeyman Ironworker and is training Slade, who is an Apprentice Ironworker, how to layout and properly tie the rebar according to the blueprint specifications. As an Apprentice Slade will spend thousands of hours under the watchful eyes of experienced Journeymen like Jimbo learning the Ironworker’s Trade.

I shot this photo of Jimbo Clark as he was tying the mat for the new roadway that will carry eastbound traffic onto I-71 North out of downtown Louisville. I liked the way the concrete abutment and the rebar for the barrier wall framed Jimbo in the shot. One other interesting thing about Jimbo is his love of photography. Almost all of the people on this job carry smartphones and snap photos of one another throughout the course of a day though few have as good an eye for composition as Jimbo. Jimbo shared several images on his phone with me one day and I was really astounded by the way he had framed his shots. When he told me he had been carrying a camera with him since his early days as an Ironworker I understood that he too was an avid photographer.

One of the great pleasures of being a Heavy Highway and Bridges Construction photographer is getting to see the sunrise. Building our nation’s infrastructure is a demanding job that requires the women and men working there to face the elements each day. Many of them have commented to me about a beautiful sunset that they saw that morning especially if I get to their section later in the morning and fail to see what they saw. In this image I wanted to tell the story of how the day begins as the sun rises and the workers gather their tools and get their work assignment together.

Whenever you see the Road Grader on the site you can be sure they are preparing the new road bed for the next phase of construction. The size and power of these massive machines is needed to move hundred of truckloads of gravel into place and leveled according to the plan specifications. On the Ohio River Bridges Project there in only one such grader working in Section One; it is operated by Neil Childress, another member of the Operating Engineers Union Local 181 in Louisville, Kentucky.

This view of the area by Slugger Field shows the progress being made on the current phase of Section One. On the right side you can see the cap for carrying the girders for the new roadway. On the left can be seen another cap that has been formed and will soon have concrete poured inside to make another pad for the girders that will carry the road. In the background the first completed section of southbound I-65 is clearly visible as it passes by Slugger Field.

In the image above two Carpenters are working together to build a catwalk and safety rail around a concrete form for a bridge cap. Safety is paramount on the job and shows the commitment of the workers to preventing injury to anyone on the job.

While building these concrete forms it is important that the Surveyors measure and verify that everthing is within the design specifications. In this image a Surveyor is being helped to get on top of the concrete form to take measurements.

I couldn’t resist taking this shot of the shadows formed by the steel girders and cross braces that placed cast initials on the ground. I took it as a sign that I am where I should be at this time and that my desire to document the Ohio River Bridges Project is the right choice for me.

 

Carpenters Working On Concrete Forms (Gallery)

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.

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.
