Last Thursday a significant milestone was reached in the Ohio River Bridges Project. After months of preparation Walsh Construction placed the first “tub”, a concrete form weighing over 240,000 pounds, that will be used to construct the western portion of the waterline footing at Tower 5, the pier nearest the Indiana shoreline. With that accomplished the foundation work on the bridge broke the surface of the Ohio River for the first time.

The yellow tub is the form that will retain the wet concrete that will be poured to form a portion of the waterline footing. The tub, which is 61 feet long and 22 feet wide was lifted and placed over two 12 foot diameter permanent casings that have been placed in the river after drilling over 30 feet into the bedrock of the river. Once those casings were in place they were filled with a steel reinforcement structure and poured concrete. Those two drilled casings were then used to secure the tub form that will be poured full in a single continuous concrete pour later this month. This is a massive concrete pour that will require the installation of a cooling system to handle the heat generated by the concrete as it cures.

Watching the crane operator lift and move this massive structure was very exciting. The longer I work with the men and women from Walsh Construction the more I appreciate the amazing amount of coordination that is required between the people on the ground and the crane operator to safely handle incredibly large structures. The crane operator had to be able to smoothly and safely lift the tub from another barge in the river and then pivot 90 degrees without allowing the load the swing or sway as he moved it into position over the two pier casings. His skill and the planning that went into making this “critical lift” paid of as the form was lowered into it’s final position and secured to the piers. This was the first time something like this has been done and it went exactly as planned.

The image at the top of the post is a three frame bracket set at +2, 0 and -2 EV which was first merged in NIK HDR Efex Pro 2 and then finished in Aperture 3. I am also including the zero EV image, which I adjusted in Aperture 3, at the bottom of the post to show why I  use HDR techniques. Using HDR techniques enhances the final image and reveals details in a much broader range than is possible when simply using a single frame and trying to adjust it for the very broad lighting situations that working in the field with available light presents.

The position of the hook and the man’s shadow on the rust colored sheet pilings really drew my attention. I processed this image with Topaz Clarity and Aperture 3 to enhance the texture and colors while maintaining the warmth of the early morning sunlight on the scene.

Construction Cranes

One of the most iconic pieces of heavy equipment on any major construction project is the crane. These monsters are essential to the Ohio River Bridges Project. Wherever I see cranes I can be sure there is some heavy work being done. They are used to move the massive steel beams, heavy timbers, sheet piling, concrete forms and other large items on the ORB. The crane operators have to be able to move their loads into very precise positions in order for the people on the ground to perform their tasks. The hand eye coordination required is incredible especially when you consider that almost all communication with the crane operator is done via hand signals. The more I am around them the more respect I have for their skills moving items that weight in the tons safely and precisely.

The difficulty I face when shooting cranes is my desire to include their long booms in the composition. Unless there is something else in the sky they can become nothing more than tall vertical elements. When I shoot them I look for mornings when the sky is filled with clouds or the sun is rising behind them. In this image I was able to include the heavy clouds for a background. I used the cranes themselves as repeating forms that provide strong diagonal lines within the composition and convey the scale of the scene.

This image is a HDR created from my standard three frame bracket set of +2, 0 and -2 EV. I merged them in NIK HDR Efex Pro 2 and did my initial tone mapping there. I then returned the file to Aperture 3 where I adjusted contrast, color channels, saturation and vibrance. Finally I applied my sharpening and added a small vignette to focus the viewer’s eyes within the frame.

This is another shot from Tuesday morning. I liked the way the silhouette of the crane operator and the hook were showing on the sheet pilings. I used a single frame in Topaz Adjust to create the image. After Topaz Adjust I returned it to Aperture 3 where I boosted the color saturation and vibrance to reveal the early morning colors. Download a free trial of any or all the Topaz Products at the link below:

I shot this image yesterday morning just after sunrise. I especially liked the way the hook and the crane operator, Cedric, were silhouetted on the rusty steel retaining wall. The morning light was simply gorgeous and I have several other images that really reveal the wonderful colors. While processing them I decided to see what one would look like in Black and White. I wanted to create an image that felt like it might have been taken at the turn of the twentieth century.

I used the normal exposure value of 0 EV which rendered the scene very well. I first processed this image in Topaz Adjust as a faux HDR image which allowed me to emphasize the colors and texture. I then took the resulting version into OnOne Perfect B&W where I applied the Ambrotype preset. I also added a border within OnOne Perfect B&W using the Emulsion 003 setting with a wide border size. I didn’t need to do anything else, except to add a little sharpening, when I returned the image to Aperture 3.
