He suggested that we could request PM to install "BLOCKING" - a piece of wood that goes across the studs - which would help flat-screen TV installation. Posting this as i am hearing this term the first time.
Google search revealed that this is more useful for cabinets. http://en.wikipedia.org/wiki/Blocking_(construction)
I called my PM - he said that blocking can be installed - i just need to let him know where the Flat screen should go.
Plumbing is half-way thru, Electrical connections in progress, bath-tubs have arrived.
