The session will demonstrate how early coordination between facility operators, engineering teams, and modular building providers can streamline project execution and reduce costly changes during fabrication and installation. Real-world examples will illustrate how comprehensive front-end planning enables modular buildings to be safely integrated into complex chemical and petrochemical facilities while meeting applicable codes, safety standards, and operational requirements. Attendees will gain practical insight into how a disciplined project planning process can improve communication between stakeholders, accelerate engineering timelines, and enhance project outcomes for industrial facility infrastructure projects.
