I'm abit doubtful with your sister PM skill..

RM700k include what item? Based on your photo, you should have finalized your roof design c/w shop drawing for Approval..

For all Mechanical works, should us piping should have proceeded as per design.. How come you still looking for WC or any other fitting..

For electrical works, u need to finalize your contractor ASAP as the brickworks is moving.. Does your project have a M&E consultant?

do you mind to mentioned what does the RM700k has covered so far? From the photo I can listing down for you the following items :-

A) Roofing
B) window + glazing
C) floor finishes (natural stone, tiles, timber flooring or etc)
D) wall finishes (ditto)
E) painting works
F) hard landscaping works
G) soft landscaping works

If your RM700k hasn't include the above work.. Better start planning your financial as well as finalize your design...
