Background/Discussion
The lighting for the Mid-America Center ballroom and pre-function areas was installed when the building was new in 2002. The dimming controls for this lighting were no longer functioning and replacement parts for the system were unavailable due to the use of compact fluorescent lamps used in the main pendant fixtures and high wattage halogen bulbs used in the downlights. The use of these lamps also contributed to high utility costs.
The work included the replacement of the dimming system with new components that are more readily available for repair and will allow for future changes in equipment without replacement of the system and retrofitting existing fixtures with LED lights that will reduce the amount energy used at the facility. Materials included new retrofit led light fixtures to replace the 250 watt halogen downlights, retrofit led light modules for the compact florescent pendant fixtures, new dimming modules compatible with the retrofit and existing light fixtures, associated wiring, partition sensors and new control interfaces for the different areas.
There were two change orders totaling $10,718.00. One for the repair of a pendant that was not properly supported and a signal wire modification to better control a group of lights to reduce additional light rigging during events. The second change was to retrofit the cove lighting in the ballrooms with led lamps for additional utility savings.
