Integration of design, engineering and construction (D-E-C) aligned to collaborative networks (CN’s) is about overcoming traditional barriers. Collaborative Network systems are submitted to economic, social and environmental circumstances. D-E-C integration linked to CPFR and submitted to CN’s could bridge traditional barriers, when aligned to an agreement and a joint business plan. CPFR contains four levels and eight collaborative tasks and was initiated and co-led as CFAR by Wal-Mart in 1995. CPFR offers entrance to a synchronized process and identified partners submitted to a joint workflow management system. Limits to arrive at D-E-C integration are indicated by defining ontology (a theoretical model) on interdisciplinary activities.
