Agency Institution Facility ID Facility Name University of Wisconsin Oshkosh 285-0F-0061 Heating Plant

Project ID Project Title 19G2T Heating Plant Chiller & Cooling Tower Replacement

Project Intent

This project provides investigation and research, pre-design, and design services in accordance with the DFDM Consultant Policy & Procedure Manual to fully build out a 4,200-ton chilled water plant by replacing the smallest chiller machine and its associated cooling tower. The chilled water plant, machines, controls, and piping will be evaluated to identify deficiencies, develop design solution alternatives, and recommend appropriate corrective measures.

Project Description and Scope

Project work includes replacing the 450-ton centrifugal chiller with associated cooling tower, pumps, piping, valves, controls, motors, and electrical service with a new 1,400-ton chiller and cooling tower. The new chiller unit and controls will be connected to and integrated with the existing chiller machines and controls to work in tandem. The expanded central chilled water plant will provide adequate capacity for all 22 buildings and/or building wing additions and 1,752,963 GSF connected.

Background

The chilled water plant addition (98179) was originally designed for the installation of three 1,400-ton chiller machines. The original plant was established in 1998 with two units and a combined 1,850-ton capacity. A direct-buried piping system was installed for the distribution of chilled water to campus facilities. Those initial facilities included Arts and Communications, Halsey Science Center and Reeve Memorial Union. This initial project installed one new 1,400-ton electric centrifugal water chiller and one refurbished 450-ton unit taken out of service at UW-Whitewater. In 2004, the chilled water plant was upgraded to its current 2,800-ton capacity (04H1S) by installing a second 1,400-ton chiller. Piping was extended to an additional five buildings where the existing chillers were 30 years old, past their life expectancy, and used regulated refrigerants (CFC an CHFS). These facilities included Clow Social Science Center/Nursing Education, Dempsey Hall, Elmwood Commons, Polk Library, and Swart Hall. From start-up of the expanded plant, there were leaks. Extensive repairs were completed in 2003, but these repairs failed to fully resolve the problems. Additional repairs were completed on the 450-ton cooling tower and both 1,400-ton cooling towers were replaced, with the expectation that the plant would be able to produce 3,250-tons of capacity. The chilled water system piping completed under the previous cooling towers replacement (12B2Q) project was designed and sized to facilitate this planned upgrade in capacity. This project was enumerated in 2019 Wisconsin Act 9 as one of five components in the combined systemwide utility repairs, renovations, and replacements request.

Analysis of Need and Project Justification

Buildings located on all of the UW System campuses are served by a variety of utilities, which are critical to their operation, and have a replacement value in the hundreds of millions of dollars. Repair, renovation, and replacement of these systems is a constant process requiring a substantial and consistent investment. Routine maintenance is supported by the operating budget. In addition, each biennium the UW system identifies critical repair and renovation projects to be funded through the capital budget, as well as replacements for systems beyond their expected service life and/or where repairs are no longer feasible. This proposed scope of work is considered to be the most efficient, practical, and economically justifiable to meet present and future needs of UW-Oshkosh. A campuswide central utility master plan was completed in 2010 and during the design process for the recent Fletcher Hall addition and renovation, the master plan conclusions and load demand data were updated to include the recent additions of Sage Hall and the Horizon Village, which reflected a total campus load of 3,093 tons. The Fletcher Hall addition and renovation added an additional 283 tons of load to the already overloaded chilled water system. The installation of a third chiller will allow several additional facilities to be connected including Albee Hall, Donner Hall, Evans Hall, Harrington Hall, Kolf Physical Education, and Stewart Hall.



Department of Residence Life and Conferencing Services utilizes all of the campus residence halls during the summer to house camps, conferences and attendees to the major events in the City of Oshkosh including Experimental Air Adventure (EAA). This event alone brings thousands of local, national and international guests to the area. In order to offer the accommodations and provide a source of revenue to the campus, air conditioning is necessary. By offering these housing options during the summer, this allows our campus to keep the rates down for student residents during the academic year.

Consultant Requirements

Consultants should have specific expertise and experience in the design and coordination of campus chilled water systems, chilled water production and distribution equipment, cooling towers and related electrical and mechanical control systems as part of a design team. Work includes site surveys, acquiring field data, and verifying as-built conditions to assure accurate development of design and bidding documents, and production of necessary design and bidding documents. Consultants should indicate specific projects from past experience (including size, cost, and completion date) in their letter of interest and when known, include proposed consulting partners and specialty consultants.

The consultant will verify project scope, schedule, and budget estimates, and recommend modifications as required to complete the specified project intent. This project will develop a design solution, plans, and specifications beginning with the conclusions and recommendations documented in the 2010 campuswide central utility master plan (07A2Q) and the subsequent follow up analysis conducted during the design of Fletcher Hall Addition & Renovation (13B2B). A Design Report will be published at the 75% project development stage and be used as the basis for seeking construction authority from the University of Wisconsin Board of Regents and State of Wisconsin Building Commission. Upon release for construction, the consultant team will develop bid and construction documents and provide construction support services. The scope of services will also include an evaluation of issues related to plant operating efficiency and operability and final placement of the plant on the site identified below. Landscape protection and rehabilitation will be expected throughout the distribution route. The consultant team should have expertise in the design of institutional central chilled water systems comparable to those at other University of Wisconsin campuses and Wisconsin Division of State Facilities design guidelines.
