Answer-
Labour productivity : productivity can be defined in many ways.
* In construction, productivity is usually taken to mean Labour productivity that is a units of work placed or produced per man hour. The inverse of labour productivity,man hour per unit (unit rate), is also commonly used.
*productivity is the ratio of output to all or some of the resource used to produce that output. Output can be e homogeneous or heterogeneous . resources comprise labour,energy, raw material etc.
Productivity = output / Labour cost
* horner and telhouni stated "A popular concept in the USA, and increasingly in the the UK, is the concept of earth hours. it release on the the establishment of a set of standard output or norms of for each unit operation. Thus a number of earn hour are associated with each unit of work completed."
* productivity may then be defined as the ratio of earn to actual hour. the problem with this concept is in establishing reliable norms for setting standard. it also depend on the method used to measure productivity and on the extent to which account is taken of all the factor which affect it.
* at the project site, contractor are often interested in labour productivity. it can be define in one of the following ways:
Labour productivity = output / labour cost
Or
labour productivity = output / work hour
there if no standard definition of productivity and some contractor use the inverse of above,
Labour productivity = labour cost (work hour ) / output
there are however, a number of different productivity measures that are commonly used. choosing between them usually depend on the purpose of the productivity measurement and the availability of data.
