Renovation of a library in Glenview, Illinois. Completed plans call for the renovation of a library.

As of September 15 , 2025 project was awarded to Martin PetersoN but awarded amount is not available. Sealed bids will be received by the Glenview Public Library hereinafter known as the Owner, for work performed for the Glenview Public Library Humidifier and Fan Motor Replacement Project. The purpose of this Request for Proposal (RFP) is to solicit licensed and qualified mechanical contractors for the replacement of two existing roof mounted humidifiers "H-1" & "H-2" (Nortec GSTC200; 200 Lbs/Hr. steam (280 MBH Gas Input)) serving two existing roof mounted air handling units RTU-1 (AAON RL-075; ~65 tons, 796 MBH heating capacity) & RTU-2 (AAON RL-095; ~80 tons, 1096 MBH) with new humidifiers of the same capacity. The units are located outdoors on the roof. The replacement is due to recent premature failures of the existing units as well as difficulty to maintain due to the current humidifier configuration. In addition, this RFP also includes the replacement of (2) 25HP fan motor, serving the existing RTU-2, located on the roof. The fan replacement shall be in kind and shall match the existing fan configuration. The contractor shall perform a pre-balance report and shall include all costs to balance the RTU to match the existing airflow. The additional motor will be retained for future use. The substantial completion date for this scope of work is to be no later than November 14, 2025. Bids will be held good and may not be withdrawn for a period of 60 calendar days from the date of receipt. Library Board project approval is anticipated to occur at the August 21, 2025, meeting of the Board of Trustees. Commencement of the work on the project shall be to the discretion of Owner. The Owner reserves the right to waive any irregularities and to accept any or reject all bids when, in the opinion of the Owner, such action will serve the best interest of the Owner Q/A :- Questions must be submitted via email, to Operations Director Jean Sanders at jsanders@glenviewpl.org no later than August 1, 2025, by 5:00 p.m. (CT). General Facility Description The existing Glenview Public Library opened in 2010 and is a two-story building with a basement and parking garage. The facility mechanical systems include large roof mounted VAV air handling roof top units, boilers for heating which are controlled by a central DDC controls system. In addition, a Fleck 5600SXT water softener system is present for water treatment. The mechanical systems are regularly maintained as well as the existing humidifiers (See Appendix B for current humidifier maintenance efforts). As a precursor to this project, the library has obtained recent water test data (see Appendix A) which should be used by the bidding contractor in selection of the replacement equipment as well as any required accessory equipment to ensure equipment longevity and ease of maintenance. The facility reports no current humidification issues, so a humidifier of a similar capacity is anticipated. It is the responsibility of the bidding contractor to evaluate all options submitted based on field investigation and the installation should include all manufacturer's recommended components and accessories. Approved manufacturers for the replacement unit are driSteem and Armstrong. It should be noted that Nortec / Condair brand humidifiers shall not be used. The following sequence of operation is taken from the original design documents, and should be verified with existing facility engineering as correct and followed for the replacement units.
