A lean approach to the planning of the construction process is a strategic challenge to analyse and manage organisational and technical factors that characterise decisions. Towards a non-schematic, non-repetitive, shared planning, construction managers need a flexible technique, tailored to the organisational process and able to represent an articulated semantic of the construction process. The in-progress research aims at the application of a planning technique, that permits flow processes to be represented through plan state sequences . Based on a careful description of activities, it may be possible to manage an interface analysis and to explicitly outline the complex frame of constraints put backward by every activities sequence. The objective is to support the contractors and the construction managers at the planning stage, paying attention to risk factors influencing quality and constructability performances. A planning system model representing interrelated construction activity requirement and performance data sets of is proposed. The aim is to extend the temporal and resource constraint of traditional planning techniques to sets of detailed constraints, formally described as conditions and effects, logically connected to pursue a quality goal. Quality planning requires clear decision traceability, planning consistency related to information availability, partial planning integration and flexible replanning while respecting external constraints. Related work and an experimental schema of integrated techniques oriented to a quality management implementation program are presented.
