Remember; you’re ocean front, and most likely in 20 years it’ll look the same regardless of equipment manufacturer. That’s just my opinion based on location.
I’ve seen integral tracks replaced yes…with common type bolt on door equipment (GAL) but there are extra modifications to align or integrate old with new and it adds quite a bit to the labor portion of the bid. And if the hoistway side (hallway door equipment) is modded, the car side will have to be as well. I’m not even sure Otis would have a direct replacement 20 years later, but it might be worth looking into to save a ton of money with one phone call. But for the most part, GAL Manufacturing door equipment has remained nearly unchanged for over 30 years. There are available replacement parts for nearly all types of their door equipment, so they are a good choice. But again, Otis may offer a straight replacement as well with minimal corrections to existing equipment. Hard choices now, but whichever way you choose it’ll be easier in the future because it won’t be you choosing! Just kidding. So you’ve got a bit more homework to do, but you’re smart in asking for advice.
Here is the official OTIS recommendation:"After discussing extensively with our lead field engineer, it is our professional recommendation to replace the car and hall hanger rollers, eccentric rollers, interlock assemblies and gibs, at each landing serviced by the elevator. We would be replacing all the moving parts. We will also sand the tracks to remove rust, paint and lubricate them. Price $13,500
Since you have integral tracks and hangers, a full track and hanger replacement would also require Otis to replace the car door and all hall doors, since the current hanger assembly is attached/integrated with the doors. The new style of tracks (Otis Mod Tracks) has a different footprint than your existing tracks so they wouldn't be a like-for-like swap out (likely require additional engineering by Otis to make them fit properly without having big holes/gaps at each floor).
Doing so would cost between of $50K-80K and have very long lead times...therefore, we are confident the attached scope of work will significantly improve the condition of your equipment and be a more cost-effective solution"
Sounds like the best -"only" path forward?
