In this photo William Moylan is working with Garran Wesseman who is standing on the right hand end of a side girder on Tower Three of the Downtown Span of the Ohio River Bridges Project. This was the first section of the downtown span that was attached to Tower Three and marked another milestone in the construction timeline. After this section was placed all three towers were supporting sections of the new bridge.

The surveyors continuously monitor the placement of the bridge components in order to make sure that the bridge is staying true to the design specifications. Their survey equipment is all electronic and communicates the measurements to the surveyors and engineers in real time so that the decisions they make are accurate.

The Surveyor… William Moylan

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.

The surveyors on Walsh Construction’s Ohio River Bridges Project are a critical part of the bridge building process. Without them the whole project would grind to a halt. By continually measuring and checking the installation of the foundation components these folks assure that everything goes into place exactly as called for in the plans.

This image is a three exposure bracket set that was merged and tone mapped in NIK HDR Efex Pro 2 before being returned to Aperture 3 for final adjustment. By using HDR techniques I was able to handle the wide dynamic range that was present due to the strong backlighting of the sun in the clouds behind the surveyor.
