Answer and Explanation:
The approximate estimates refer to the prediction of the nearest value while on the other hand, the detailed estimates refer to the estimation of the project or product that required a detailed analysis
based on the above explanation, the classification is as follows
A. Detailed estimates. As it required completed documents with respect to the design that needs comprehensive analysis
B. Approximate estimates. As the bidding is used so it required only approximation estimates
C. Approximate estimates. As the feasibility studies are used so it required only approximation estimates
D. Detailed estimates. If the project required high effort so detailed analysis should be there.
E. Approximate estimates. For comparing the alternative projects we needed detailed estimates
F. Detailed estimates. For project control, we required nearest value estimates
G. Approximate estimates. Since there is a high margin of error which required only prediction values to the nearest value
H. Detailed estimates. For making initial financial arrangements we need detailed analysis
I.Approximate estimates. For comparing the unit cost with respect to the same last projects we need prediction estimates
J. Detailed estimates. Since the concept based on actual quantities and there is a prediction price for estimating the project so in this we required detailed estimates.
