Archipelago Parking Ramp

Madison, WI
Partner: Potter Lawson
Size:163,427 Square Feet

The Archipelago Parking Ramp is part of a larger redevelopment on the East Washington corridor. It has 390 stalls to provide parking for WHEDA employees with a third-floor, fully enclosed skywalk leading directly to the office. Reserved parking is also available for Hotel Indigo guests.

The project started by removing 18,759 tons, or 987 dump trucks, of contaminated soil from the site. After clean fill was brought in, 379 piles — averaging 32 feet in length — were driven into the ground for support. This is our largest post tensioned (PT) project to date with over 5,200 cubic yards of concrete for the decks and 817 cubic yards for the columns — a total of 666 truckloads!
