The Contractor shall return all work areas to the condition that existed prior to any work being undertaken. The expectation is that there will be minimal disruption to agency workspaces or missions. Work needs to be coordinated to determine if some work can be accomplished during normal working hours.

Upon contract award, the Contractor shall conduct an initial planning meeting with GSA Property Manager and the facility manager. The Contractor shall have its Implementation Plan (Section 2.6) prepared for referencing against the building tenant housing plan. The Contractor shall maintain detailed tenant impact documentation as part of the Implementation Plan based on dates of construction work impact, floor level, and tenant impact. Tenant areas under construction which may require guard service at night during unoccupied hours shall be identified during the design phase, so that appropriate RWA may be obtained.

Additional items for coordination are the Contractor’s security plan, safety plan, and work hour scheduling.

In public areas, the construction work shall be conducted after hours unless approved by the GSA and GSA Property Manager. Design and management site visit inspections may occur during the day. As part of the Contractor’s Implementation Plan, the Contractor shall provide a design visit schedule for GSA review, as well as any proposed testing or sampling. Any light construction activities or construction in non-occupied areas of the building proposed by the Contractor for normal work hours will require approval by the GSA and the facility manager.

A building housing plan for tenant location and floor plans are provided as reference documents. These documents indicate where a Federal agency is located, the limits of its occupancy, the rooms, and room numbers for the rooms. The room numbers on the CAD floor plans are from a design document room tag numbering system, and the actual room number signage in the building is a different room signage numbering system. The Contractor in indicating work areas should provide dual designations for work areas – CAD floor plan designation and room number signage.

Below is a summary listing of the tenants by floor level in the building; recent relocations, if any, need to be confirmed on site. Refer to the Drawings for existing tenant information on floor plans.

Historic Preservation

General Requirements and Guidelines The following section provides general requirements and guidelines for minimizing the impact on the historic fabric of the Milwaukee Federal Building and U.S. Courthouse where the fire protection system will be upgraded or replaced.

In Zone One and Zone Two rooms, the devices and electric conduit routing will impact the historic materials and appearance of the space. The proposed fire detection and voice evacuation fire alarm design will comply with the applicable requirements and guidelines listed below. Specific Federal guidelines for adding new fire detection and voice evacuation fire alarm systems to historic buildings are published in the document Fire Safety Retrofitting in Historic Building and the 2018 version of the PBS- P100. Where guidelines do not reference a specific Federal document, they are based on historic preservation “best practices”; these guidelines are summarized below.

Coordinate the location of all fire detection and voice evacuation fire alarm devices with both the GSA’s Fire Life Safety and Historic Preservation Staff.

Install smoke detectors, heat detectors, fire alarms and required electrical conduits so that they are not unusually prominent or do not affect the significant historic fabric of a building (Fire Safety Retrofitting in Historic Building, pg. 20).

Select the style of alarm devices so that its appearance is in harmony with other architectural elements of the historic building (Fire Safety Retrofitting in Historic Building, pg. 20).

It is not recommended to install smoke and heat detectors in historic plaster relief or cornices (Fire Safety Retrofitting in Historic Building, pg. 20).

In compliance with all code requirements, where possible, smoke detectors will be placed to minimize destruction of ornamental surfaces. Where ceilings are elaborately embellished, explore alternative detection products and approaches such as air sampling detection, projected beams, low-profile spot detectors, recessed installation, or custom-coating detector housings to blend with ornamental finishes. Application of special finish treatments outside of the standard factory process will be coordinated with, and approved in writing by, the manufacturer to ensure that UL labels and detector performance are not compromised. Smoke detector housings will be removed before application of special finishes (PBS-P100, pg. 222). It is not recommended to install smoke and heat detectors on the surface of ceilings that are historically significant (Fire Safety Retrofitting in Historic Building, pg. 20).

It is not recommended to install fire alarm pull stations in such a manner that they detract from or permanently change the appearance of the historic building or area (Fire Safety Retrofitting in Historic Building, pg. 15).

All electrical conduit routing will be carefully planned to minimize cutting and patching of historic material. This may include installation from a non-, or less, historically significant space where feasible (e.g., installation of conduit for a highly historic space from the backside of a wall in an office space). The Contractor shall create as many inspection openings as necessary to determine adequate routing.

All electrical conduit in Zones One and Two is to be concealed.
