Proposal: Lean Construction applies a production philosophy from manufacturing to building. Lean production was born on the factory floor and is an ensemble of empirically tested principles. The lack of a theory that explains why and how such principles work raises doubts if the can be applied to the construction environment. One of such principles is reduction of lot size as way to reduce lead time and this paper aims to use the learning curve to explain how and why this lean principle works Methods: Mathematical deduction and simulations from productivity data gathered from a building sight. Findings: A mathematical demonstration explaining how in line of balance programming of repetitive high rise buildings a reduction of lot size understood as the choice of smaller repetition units implies a reduction in lead in the presence of the learning effect. Originality/value: The use of the learning curve to supply a theoretical base and a mathematical underpinning of why and how a lean construction principle works.
