Scope

Michels constructed an underground water retention cistern inside of an occupied apartment building. Due to historic water levels in Milwaukee, WI, a parking garage had been underwater and inaccessible since March of 2019.

Michels' scope included dewatering the site and excavating below the water table to construct the cast-in-place concrete cistern with a traffic accessible precast concrete lid and drive surface.

Residents of the building were notified weekly of all updates from the property manager, including when materials were moving and when crews were pouring concrete, to ensure minimal disruption.

The work site was a 75 by 75 foot below ground parking garage. To locate the generator to power the dewatering equipment, a barge was required as three sides of the site were landlocked with a river on the north side. Crews also strategically maneuvered equipment around the site due to some areas with low overhead clearance.
