Title
Public Works Emergency Rooftop Make-up Air Unit Replacement - Proposal
History
The Vehicles & Equipment (V&E) area of the Public Works facility uses Makeup Air Units (MAU) to “condition” air in the mechanic bays. Makeup air units are typically used in spaces where the air within a building or room cannot be recirculated and must be exhausted to the outside like a mechanics garage where fumes must be positively ventilated. The makeup air units bring in fresh air from the outside to replace the less than ideal air that is being ventilated. The V&E application of the MUA’s, ensure that during the spring and summer months, the makeup air units simply brings in outside fresh air without altering (conditioning) the temperature of the outside air flowing into the space. During the cooler fall and colder winter months, the makeup air units are designed to heat or “condition” the air to keep the space warm.
V&E has three rooftop makeup air units that have gone well past their useful operating life. In spite of numerous attempts to repair the units, all three units have failed. Staff requested and received a proposal from the Village’s preferred qualified provider, the CTS Group of Chicago, IL. CTS was competitively selected by the Village of Orland Park in June of 2015 to provide researched turn-key proposals and competitively priced and fully engineered solutions, with installation oversight being managed by the CTS Group.
CTS has provided the engineering and selection of the following makeup air units that will efficiently and effectively serve the Public Works facility. The units have been selected to reduce energy, meet capacity requirements, and provide ease of maintenance for village staff.
CTS recommends the following makeup air units for the V&E area. The Village of Orland Park will install the units in-house with staff.
