One of the main characteristics of construction is that work flows through temporary production systems from the start to the end of a project. The way the production system is designed has a major influence in the outcome of the project. This paper presents a case study on rebar that illustrates how the application of PULL and CONWIP techniques can drastically improve value delivered. Benefits include reduction in physical inventories, an increase on transparency across the production system, reduction in variability levels for both demand and supply, lead time reduction, and better collaboration amongst stakeholders.
