Abstract

The selection of formwork systems in high-rise buildings is often governed by their competence in optimizing concrete activities in an isolated manner, without relating this choice to the entire construction workflow. Known research efforts do not address this important aspect in analyzing high-rise formwork technologies, and formwork selection is usually left to constructors’ experience, and corresponding organizational knowledge. In this context, this paper studies the role of formwork systems in high-rise construction from a lean perspective and analyzes this role in shaping not only the progress of concrete activities, but the entire construction sequence. Employing lean concepts, the paper investigates advanced high-rise formwork systems versus traditional ones to better advise scholars and practitioners. Results highlight the importance of advanced high-rise formwork systems in streamlining the workflow of concrete and other downstream activities, allowing for more waste reduction, smaller work batches, less inventory, and safer working environment. This study is a conceptual framework for future related works involving case studies and field investigations, and may be further developed to target more aspects of high-rise construction.
