FOREWORD,
0. This Indian tandard ( Part I ) was adopted by the Indian tandards Institution on 15 March 1974, after the draft finalized by the Planning and Organization at ite ectional Committee had been approved by the Civil Engineering Division Council. chedule of rates form the basis for preparing the detailed estimates for works. These are also very useful in considering the reasonableness of the tenders received from the contractors and for pricing the alterations, addiIt is, therefore, necessary tions, omission and substitutions in a contract that the schedule-of rates should be prepared correctly and be based on rationally stipulated material and labour constants. 0.3 At present different departments at a place are having their own schedule of rates. A comparison of the labour and material constants used for different items of work in these schedules of rates has indicated that there is a good variation in them and due to which different rates exist in various departments for the same items of work in the same locality. This standard is being issued in order to rationalize the labour output constants for different buildin works. 0.4 The labdur constants have been arrived at by the Central Building Research Institute, Roorkee by taking actual observations, using wor measurement techniques, on the construction sites at Delhi and Roorkee. Different types of building works up to 10 m height of CPWD, MES and other organizations were included where the workers from neighbourin ufficient number of observations to ensure a confidence states were working. limit of 95 percent and an accuracy of f5 percent were taken. The relaxation allowance for the time required for rest to overcome physical fatigue and working condition allowance has been taken as per the standardized values given for Indian conditions b y the Ministry of Labour, Employment and Rehabilitation, Government of India. Other allowances, such as organizations, incidental holdups, ineffective time arising out of preparatory work and additional weightage for small size works have been arrived at by the activity sampling studies and mutual agreement at the committee meet-

.5 For the purpose of deciding whether a particular
requirement of this standard is complied with, the final value, observed or calculated, expressing the result of a test or analysis, shall be rounded off in accordance with IS 2-1!330*. The number of significant places retained in the rounded off value should be the same as that of the specified value in this standard.
1. S C O P E 1 .l This standard ( Part I ) covers the recommended labour output constants
for general items of building work for north zone which comprises of the following areas: Punjab, Haryana, Delhi, Uttar Pradesh and Rajasthan. 1.1.1 The labour constants for other zones would be covered separately
