Someone in the handover department told me they will start in 2-3 weeks. They will do it in a phased manner.
Based on my phase 3a experience, don't have very high expectations. Expect long delays in the defect rectification process. They will start with a bang then trickle down to a whimper. Lots of promises, very little action. Deadlines and promised dates mean nothing. What is promised in a week could easily be a month. It's almost like standing and watching paint dry up on wall.
My 2c, be on top of things. Be prepared to make frequent trips. Chase them to death. Be ready to escalate to senior management. Last but not the least, make sure you reiterate all communications by email and document everything. Click pictures and attach them to your email communications in a PDF file.
Oh, unless you are in a big rush, don't start your renovation before they do defect rectification. As long as it takes. Otherwise the blame game and finger pointing will start. I made that mistake. One more tip - don't be too nice. The stick works better than the carrot. Learnt that the hard way as well.
Good luck bro! As much as you have just heard me whining and complaining, overall, I am still very happy with what I got for the price paid. I have no regrets about my decision to buy from them and would recommend them in a heartbeat. UEM is a great company overall. It is just that the project department that needs to get their act together. I am sure they will get there. Rest of the departments rock!
