1.	In earthwork calculations, how many lifts are to be paid to the contractor when the earth is to be lifted for 4.5 metres?(a) Four(b) Eight(c) Twelve(d) SixteenThe question was posed to me by my school principal while I was bunking the class.My doubt stems from Estimation and Costing topic in section Rate Analysis, Estimation and Costing of Construction & Building Materials
Answer» The CORRECT answer is (a) Four To explain: In earthwork calculations, the unit of lift is 2 metres for the FIRST lift and one extra lift for every 1 METRE. Therefore, when the earth is to be lifted for 4.5 metres, four lifts are to be paid to the contractor. For the first 2 metres, one lift is needed and for the rest 2.5 metres, three more lifts are REQUIRED which sums up to a total four lifts.
