FYI, one of the recently completed (additional, # 4) elevators at BAM’s Condominium project-Treetops at Patthaya by Thyssen Krupp with 14 landings (~16 levels in o/a height, Machine room-less) was finished in about 6 weeks (to install & commission).
Hence, I am sure it will be possible for you to achieve the same schedule at BPI11 as well for installation and slow speed testing.
Please review and confirm your revised schedule. We really need to finish all elevators for Aor 6 inspection, say, by mid-October 2016.
