Hi all,
I have read that construction estimate cost in pre-planning is based on unit cost, and in schematic design is area volume. Is that right? Is it not the same?

Jennys note says during SD its based on MAJOR ELEMENTS OF BUILDING SYSTEM ( MECH, ELEC, STRUC,)

HERE'S AN IDEA NCARB , COME OUT WITH AN OFFICAL BOOK FOR THE SUBJECTS YOU WANNA TEST US ON , LIKE ANY OTHER PROFEESION!!!!
