Abstract:
In construction, the formwork supports and retains the freshly poured
concrete till the time it cures. Formwork has an essential role in the structural
works and its operations are labor exhaustive and time-consuming. Modular
formwork systems of many types are in use all over the world. These smart systems
have automated the process, improving the productivity and cost effectiveness due
to their simple and systematic fixing and striping methods along with less skilled
labor requirements, higher strength and smooth finished surface.
In Pakistan such modular formwork systems are not commonly used. It is
important to determine the impact and barriers of such modular formwork systems
on Pakistan’s construction industry which could be done by comparing the same
with the traditional steel formwork systems. For this purpose, the current study
focused on modular formwork erection and striping methodology in view of
manufactures guidelines and its comparison with traditional steel formwork.
In total, 14 on-going and completed projects were considered and related
technical data for both systems was collected to assess the practical approach and
impact on the productivity. Systematic literature review, field data, site observatory
data and interviews with professionals helped in selecting the most appropriate
formwork system considering the top ranked factors through a decision support
system. It is found that the lifecycle cost of modular formwork system is
economical. However, there is a lack of relevant skilled workforce. It is
recommended that such a formwork system be specified in contracts. Lastly, it has
become imperative for workers to be provided with necessary skills through
training programs and vocational education systems.
