Abstract:
Formwork is one of the most important factors in determining the success of a construction
project in terms of speed, quality cost and safety of work as it accounts about 40% of the total project cost
of the structure. To minimize the costs the contractor needs to complete the project as soon as possible
and the client wants the building to use the building as early as possible for the intended purpose. In highrise
building construction the most efficient way to speed up the work is by achieving a very short floor
cycle. That directly depends on the selected form work type for the construction. This paper will present
about the existing formwork types in Sri Lanka and the available new techniques in formwork erection.
This paper will clearly present an analysis and comparison of costs and durations of projects when using
different types of formworks. The main objective of this paper is to identify the least no. of typical storeys
required in a high-rise building construction project, to use aluminium panel system formwork.
