It's about eight in the morning and, as a breeze still wends its way through the area, crews are busy all around downtown, trying to get as much as possible done before the heat of the day smothers any urge to work. The men in these pictures are working to repair and replace brick pavers that have become loose or broken in the streets and sidewalks around Monument Circle.
The photo above shows an air hammer being used to chip away the underlying cement and base, not only to improve the foundation for new bricks, but to prepare it for new curbing. It's a fairly selective annihilation; even as the workers pull up the existing bricks, they're trying to save as many of the pavers as possible. Not only will this cut down on the expense for replacements, it also helps to maintain a kind of patina from daily use, which the new pavers would not have. The piles of bricks below will be blended together as they are laid in order to avoid too much contrast between old and new.
The man below is taking a few moments to verify his calculations for the number of pavers needed to complete the project. As the project manager, he's hoping he won't need to order very many more of them, if at all. Lying on his foot he has a working drawing of the area and in his hands a little contractors' reference manual used to look up formulas for various calculations.
He's got a bit of figurin' to do because the bricks are not only being replaced as needed, their numbers are being increased with changes in the layout of the streets and sidewalks. The following photo shows the markings made at the northwest corner of the intersection of Washington and Meridian Streets; it appears Washington Street is being narrowed with the sidewalks to become wider to provide a more friendly, boulevard atmosphere for pedestrians. The white marks indicate the cut lines for the workers who'll remove the pavement, but the writing indicates "Do Not Cut Bricks." Earlier I'd seen an older layer of bricks beneath the existing pavers. Perhaps they plan on using some of the them, as well, if they can be salvaged.
There aren't any letters to give a clue to the meanings of the orange and red hash marks, but that's a question for another day. These markings extend from the pavement on into the sand and gravel base of the new work. The ones shown above lie to my left as as I looked west on Washington Street to take this picture.
