Formwork Presentation

This document provides an overview of the formwork systems used for a high-rise building project consisting of 4 towers ranging from 53 to 72 floors. It describes the Mivan formwork system, which uses a 4-day cycle to erect walls and slabs, and the Automatic Climbing System (ACS) which involves climbing wall panels up the building during construction. The ACS operation involves several stages including tying reinforcement, fixing climbing cones and wall shutters, lifting and climbing wall panels up levels, and repeating the process as the building rises.
