Please don't hesitate reaching out to me for in field during construction/ finishing phase advise. Most important how to maintain the QC and nip the evil in the bud. I mean when you are dealing a "theekaydar" who don't bother listening to you and says he is doing such thing from "baap daday kay zamanay say". Everything looks good on plans but the implementation of specification, like simple sand or the major component of your building the brick, mortar and concrete is big question mark. (H)
