Just want to add further...becareful of what you sign with them..when the final bill come, be sure to check all the entries..i've got experience with entries that are supposed to be deleted but were left on the bill. ID wise, the person I engage is ****. Drawings was not delivered to what we requested.Overall if you have already engage them to do the job, tough luck but if you ar ethinking of using them, I suggest to relook into it again.. **Remember- there's no free lunch in this world. The free stuff that they promised are terrible..they used bangladeshi to do carpentry work for you. No offence to all Bangladeshi but I've never known Bangladeshi to be good in this expertise.
