AGENCY REQUEST FOR BUILDING COMMISSION ACTION September 15, 2010 DSF #: 10H1Y AGENCY: Department of Administration LOCATION: Milwaukee State Office Building 819 N. 6th Street Milwaukee, WI 53203 REQUEST: Request authority to construct a north-west exterior masonry/plaza repair project at the Milwaukee State Office Building for an estimated total cost of $649,900 Program Revenue Supported Borrowing. PROJECT DESCRIPTION: This project provides for the removal of the deteriorating plaza concrete wearing slab, drainage net and waterproofing membrane and installs a new waterproofing system that consists of a new concrete wearing slab over insulation; over a drainage mat over a protection layer of a fully adhered, fluid applied waterproofing membrane over the structural concrete deck. In addition, waterproofing detailing will be provided at all walls, transitions, drains and planters. All existing drains will be replaced with bi-level drains that accept water from the surface, as well as, water at the membrane level. In addition, the project repairs/replaces failing brickwork and the existing masonry barrier walls with new stainless steel railing system. JUSTIFICATION FOR THE REQUEST: The Milwaukee State Office Building is located at 819 N. 6th Street in downtown Milwaukee. It is a modern, ten-story, office structure with articulated window wall of precast concrete panels. The facade consists of masonry and glass with mechanically fastened foam insulation and insulcrete thin coat imbedded with white marble chips. The last cyclical maintenance done on the northwest plaza and barrier walls occurred in 1991. Currently, there is extensive spalling and failure of brickwork occurring at the exterior on the building, and on the plaza barrier walls. In addition, there is water infiltration occurring on the northwest plaza decks with occupied space underneath the deck being adversely impacted due to moisture issues. The masonry walls adjacent to the plaza have deteriorated to the point they need to be replaced and proper waterproofing and detailing needs to be performed. This project addresses theses issues though the installation of a new waterproofing system in the plaza; it repairs and/or replaces failing brickwork; and replaces the existing masonry barrier walls with new stainless steel railing system. In November 2009, the State Building Commission approved a project (DSF#09J3Q) that addressed exterior masonry/plaza repairs on the northeast section of the Milwaukee State Office Building. This request is for the second and final phase of the Plaza and Barrier Walls Project. The budget is based upon the November 2009 Condition Report prepared by an A/E consultant.
