Specifications include, but are not limited to:The State of Iowa Department of Administrative Services is currently seeking equipment recalibration services from qualified Trade Contractors for improvements to Buildings 14, 7 & 8 at the Iowa State Penitentiary in Ft. Madison Iowa.Building 1 Housing Unit 1 Building 1 has five housing wings and a center office area. The primary system that conditions the majority of the building is a variable air volume unit with chilled water and hot water in the preheat position. The AHU is sized for 50,000 CFM (summer)/ 38,000 CFM (winter) supply airflow. This AHU supplies 54 variable air volume boxes. Only eight VAV boxes do not have a hot water reheat coil. There are two large 15,000 CFM ERUs that supply air continuously to the AHU. The exhaust pulled through the ERUs comes mainly from the cells and some from the center office area. One ERU operates for two housing wings and the other operates for three housing wings. These ERUs exhaust air at a constant rate and do not vary. The outside air has the ability to bypass the ERUs and fully economize. The airflow pattern design intent is to pull air from the center office area thought the housing wings and out the cellblocks. This is achieved by putting the cellblocks under a negative pressure by design. The chilled water and heating hot water is supplied by seven water-to-water heat pumps (EcoKubes). The EcoKubes have a single-non-variable compressor the produces both chilled water and heating water from two separate heat exchanges on the evaporator and condenser. They reject heat to a geothermal loop sized for Building 1 alone and require a constant 100 GPM of water flow through both the evaporator and condenser. Each unit has an individual primary pump that have been balanced to 100 GPM to ensure this water flow is available during operation
