To plan concrete works reliably it is necessary to analyse labour demands for all the technological operations,
including reinforcement placement and formwork operations in particular. Such analyses can be made using
planner’s own experience, the data delivered by formwork producers, Polish or foreign catalouges of labour
rates. Which of those provides the most reliable labour assessment? The paper describes different sources
of information on labour rates for concrete works, including formwork and reinforcement operations. It also
presents a brief review of factors influencing on labour productivity, as well as introduces a concept structure
of a new, intelligently managed database applicable for labour prediction. Database learning and labour prediction
is thought to be made using classifier ensembles.
