Civil engineers and project managers must control and manage the project management discourse with the client and other stakeholders or risk slippages to time, cost, and programs. This paper explores how communicative choices and the representation of project requirements and engineering issues are intrinsic to effective civil engineering work. Using a social semiotic framework, the paper contributes to civil engineering learning by revealing how various engineering communications (e.g., schematic drawings, visual images) function in civil engineering contexts. The research builds upon civil engineering communication scholarship, highlighting the significance of representational choices for affecting engineering work. The social semiotic and multimodal-informed analysis clarifies processes of cognition, interpretation, and understanding at play when civil engineers interact with project stakeholders. The findings inform civil engineering education and the teaching of communication skills: communication composition being intrinsic to effective civil engineering work.
