Equipment stands at the ready over the weekend at 810 West Fulton Market, waiting to tear into the soil.

Stalworth Underground began drilling the first caissons on Monday for 801 West Fulton Market, the new seven-story office building from Shapack Partners. Stalworth tells us there will be 24 bell caissons for the site, and then Power Construction will begin going skyward. The Hartshorne Plunkard Architecture design will include commercial space at ground level, a green roof on top, and a surface parking lot. The building replaces a surface parking lot at the corner of Fulton Market and Halsted Street, just below the nearly-famous “FULTON MARKET DISTRICT” sign.
