How come that assemblies system is not more accurate than unit price takeoff?
In DD assemblies systems define more details and in which case shall proved more accurate cost estimate??
Sample question:
Which of the fallowing types of estimates is the most accurate?
A) order of magnitude
B) square foot and cubic foot
C) assemblies system
D) unit price takeoff
My answer is C- assemblies, however ncarb's answer is unit price take off? In programming the unit price ( such as per bed or per Pearson is used earlier on to define cost estimates, however as project moves on assemblies and more details of construction appear and cost estimates shall be more detailed more accurate, therefore is shall be correct answer assemblies? why Ncarb claims that correct answers to above question is unit price? Please explain.
