About this file

This document provides details for a federal contract opportunity to replace air handling units and chiller plants at the Clement J. Zablocki VA Medical Center in Milwaukee, Wisconsin. The contract will require replacing one air handling unit with a packaged rooftop unit including external steam and humidification equipment, and replacing two other units with a single larger unit including a separate rooftop air-cooled condensing unit. Additional requirements include demolishing the existing chiller system, reusing existing steam piping and ductwork, upgrading HVAC controls, and replacing mechanical room lighting with LED. The project cost is estimated between $1-2 million. The solicitation is scheduled for posting on October 28, 2019 with bid opening on December 4, 2019. The opportunity is a 100% SDVOSB set-aside to be issued by the Department of Veterans Affairs Veterans Health Administration VISN 12.

Overload Current Rating: 100% for 1 minute every 10 minutes.

The Class 10 trip rating of the MMP device will not withstand an across‐the‐line start of a fan and should not be used with VFDs with bypass circuits.

The customer must provide a platform or catwalk for accessing the power‐disconnect.

Statement of Compliance

YORK® Solution XT AHU's meet IBC seismic requirements for non‐critical equipment (Ip = 1.0) for locations with design spectral response Sds <=

0.43. Units must be rigid mounted.

The anchorage of the unit to the ground or building structure needs to be evaluated by and is the responsibility of the engineer of record.

Specification of seismic requirements is the responsibility of the project design engineer. If formal certification is required, please contact your sales representative and/or application engineer for review. Certain application and site requirements may require additional cost and/or lead time.

Component locations are listed as Segment Hand (Unit Hand): ex. Left (Right). See SubmittalDrawing for additional details Air handling unit parameters vary depending on conditions. Parameters such as airflows, air pressure drops, and coil capacities are shown for design conditions.
