The difference between Height of Collimation Method (HCM) and Rise and Fall Method (RFM) are as follows:

HCM :It is more rapid and saves a considerable time and labour.

RFM : It is laborious as the staff reading of each station is compared to get a rise or fall.

HCM : It is well adopted for reduction of levels for construction work such as longitudinal or cross-section levelling operations.

RFM : It is well adopted for determining the difference in levels of two points where precision is required.
