600 Longworth Garage Door Project

The Greater Dayton Regional Transit Authority (RTA) is soliciting proposals for 600 Longworth Garage Door Project .

The current door manufacturer is not certain, but the current garage doors operators at both the entrance and exit doors are OSCO Model GSL Bi-Parting Doors. These doors have worked very well for approximately 50 years. The bi-parting door design works extremely well for transit bus operations as compared to a roll up type door. To the best of my knowledge, these doors have never been hit by a bus entering or exiting the garage. The doors completely open in 15 seconds, stay open for 30 seconds and close completely in 15 seconds. There are approximately 250-300 openings and closings daily for each set of doors, entrance and exit, making it about 110,000 cycles per year per door. The current doors are operated with 480v 3 phase electric and are tied into RTA’s backup generator and the new door systems should operate on 480 3 phase electricity.
