The paper “Managing the Receding Edge” focuses on the challenges of completing construction activities, particularly with post-tensioned, cast-in-place concrete slabs. It emphasizes the importance of the “receding edge,” which ensures that work is fully completed before subsequent tasks begin. The study highlights the need for standard processes and proper resource allocation to maintain efficiency and reduce cycle time. Lean methods are proposed to address these challenges, aiming to keep the receding edge progressing in tandem with the leading edge.
