Description of Project: | A combination of new building construction, air conditioning upgrades to existing buildings, and the ongoing conversion of existing buildings to a central chilled water system requires the extension of utilities infrastructure on the Urbana-Champaign campus. The most cost-effective, long-term means of heating and cooling campus buildings is often via the campus central steam and chilled water utilities. The expansion of the campus to the south and the potential remodeling of Lincoln Hall in the central campus area necessitate utility system upgrades.; The project will provide a variety of campus utility improvements, including the extension of the campus chilled water system, the extension of the sanitary sewer system, and the extension of steam lines to new locations. In addition, this project will convert some existing buildings to the central chilled water system.; The chilled water mains/branch lines to be provided include:; 24" mains from First St. and Peabody Drive south to First St. and St. Mary's Road. Branch lines to buildings south of St. Mary's Road.; 30" mains from Armory Avenue near Sixth St. to Chalmers and Sixth St. Branch lines to Lincoln Hall.; The sanitary sewer lines to be provided includes:; A new sanitary sewer pipe from teh Oak St. Chiller Plant to First St. and St. Mary's Road.; Steam utility work to be provided includes:; A new shallow trench steam tunnel with piping from teh existing tunnel at Florida Ave. and First St. to St. Mary's Road and First St., with branch piping to building south of St. Mary's Road. A steam utility feasibility study will be performed initially.; Building conversion work includes:; The Speech and Hearing Building and the Psychology Building shall be converted to accept central chilled water service with variable flow, including service entrance, meter station, DDC control work, and air handling unit conversion.; Further miscellaneous utility work may be included in the project scope if it is determined other utility improvements along adjacent routings need to be addressed as part of this initiative. |
