In estimating the labour cost of a unit of work the cost of labour supervision must be considered.
The direct supervision of labour is carried out by gangers, trade foremen and leading hands, these being in turn supervised by a general foreman who co-ordinates the labour supervision and labour as a whole under the agent and his staff.
In costing work with a view to producing estimating data a decision has to be made as to what labour supervision is a direct labour charge and what is included in the Preliminaries Bill.
This is generally resolved as follows:
- Gangers trade foremen and leading hands are a direct labour charge.
- The agent and the site administrative staff and general foreman are included in Preliminaries.
