The windows at River Heights are cleaned twice a year. The elevator have had problems and finally the drive belt (a major part) required is not in stock in the Uk and is being fitted this week. We have escalated the matter through every channel with Otis, including on Twitter. And Jon Beckwith, Independent lift engineer is engaged also. We expect the lift to be transformed by the new drive belt and have out notices up on site that people jamming the lift doors open will be recharged for damages caused and that people must ask the 24 hour concierge to escort them and use the lift key when moving in and out - as this will help reduce lift failures. We are acting on all recommendations given to us by the equipment specialists but are happy for any other input that you can provide. If you are not receiving regular updtaes pleaee go ask the concierge to add you to the system. And if you would like us to arrange a call with Otis and you so you can hear 1st hand what has been going on we can arrange that too.
