Stand at the fence by PPG 2. The fire hydrant you see will be on the sidewalk by the building. When you see that, you realize how WIDE the renovated sidewalks will be. It's very surprising. There will be plenty of room for sidewalk cafes!
Here you see a compacting machine. Before you lay a sidewalk or road, you must make sure the soil is well-compacted. Dirt slowly settles over time and without any support pavement will crack. You can avoid settling by compacting your dirt first. You may see this machine at other Downtown work sites, like Three PNC's work on Market Street, a block from the Square. This is another chance to comprehend how deep pavement layers are; the mulch around the tree will be flush with the sidewalk when finished. The City-standard 3'x3' tree pits are protected during this process by fencing. This is another reason to use small, hand-held machines instead of large ones - to protect the tree pits and branches. When working on the larger open areas, where the trees will not be endangered, you will probably see larger compacting machines.
This week they are also focusing on the electricity that runs to the tree pits. They are setting the stage for the lighting that will be installed later in the project.
