Abstract:
Formwork is the largest cost component for a reinforced concrete structures. Its cost accounts for
40 to 60 percent of the cost of the concrete frame in developed country. A large proportion of the
cost of conventional formwork is related to formwork labor costs. Significant cost saving
will be achieved by reducing labor costs.
The main objective of this thesis is to assess on current application of formwork. This can be
achieved by identifying formwork types and materials used at building construction project sites
in Hosanna, by collecting factors influencing selection of formwork system, by investigate the
quality implication of current formwork practice and effects of the using current construction
practices
Among the different tools used to collect data, self-administered questionnaire in the form of both
close and open-ended questions used to collect all the relevant data used to answer the research
question. A total of 60 questionnaires were distributed to contractors & consulting firm. For
analysis a total of 57 questionnaires where used. The method of analyzing the collected data is
based on ranking the percentage of frequencies and by using relative importance index (RII). This
research used a mixture of descriptive statistics, graph and pie chart to present the collected data.
From collected data type of formwork used 65% of respondents use conventional formwork system
and the remaining 35% use modern conventional formwork system. Most commonly used
formwork materials are plywood and steel formwork materials in Hosanna town. Some of the
quality problems of using conventional formwork system are not straight vertical surface, uneven
surface and poor construction joint are some problems. The effects of using current formwork
practice high influential effect was high labor intensive, secondly limited no of reuse and thirdly
high wastage were the most three influential effects. Based on this results construction industry of
hosanna town formwork system should be improved by utilizing modern formwork system
