Deeply apologize for the inconvenience caused for postpone the schedule re-cleaning today. Due to heavy rains this early morning so the contractor contacted with us for the external window cleaning, it may not be ready today because there will be obstacles to abseil and we also predicted that may be raining again during the day which will be effected for this cleaning will not be successful. Therefore the building management decided to postpone the schedule to re-clean next time at the appropriate time so that the cleaning is accomplished.
