The Northwestern Mutual Life project required a temporary Earth Retention System to support the excavation for the new Northwestern Mutual Life office building in downtown Milwaukee, WI. MDF&E's solution was to provide a Steel Sheet Piling wall on all four sides of the excavation.

For three of the sides, we utilized one row of Hollow-Bar Tieback Anchors to assist in handling the lateral earth pressures. On the North end we utilized a second row with a waler to help support the additional load from the Whiskey Bar property.

The installation of the Steel Sheet Piling was done with an ABI Rig. The Tieback Anchors were installed with our Klemm 806-4 Hydraulic Drill Rig.

The Spincraft Machine Foundation project consisted of providing a fully enclosed Earth Retention Structure to allow for the excavation of the foundation for Spin Craft's new spinning lathe machine. Steel Sheet Piling was the system selected to complete this project. External walers with two pipe struts provided enough lateral bracing to maintain the 10'-6" deep excavation. This work was completed using our CAT 336 backhoe with a Movax SPX 100 Vibratory Hammer.

The Marquette University Vally Field Dome project consisted of installing Micropiles to help hold down a new dome over the athletic field to allow for practices in the Winter. MDF&E installed 166 Micropiles around the perimeter of the field. They were installed with an average length of 80'-0" and at a batter of 30º from vertical.

Proof tests were performed on 5% of the production piles. These Micropiles were installed using our Klemm 806-4 Hydraulic Drill Rig.
