a. Machinery breakdown

b. Power failure

c. Accidents

d. Drop in the efficiency of workers.

e. Drop in the efficiency of machines and tools.

f. Strikes.

2. Avoidable Errors: Some of the errors can be avoided by the estimator while preparing the estimates. These errors may occur due to less experience, carelessness and hurry in preparing the estimates.
