Abstract:
Construction industry is universally criticized due to failures to deliver projects on their
planned objectives. This situation is severe for housing cooperative buildings which are
executed with limited saving sources. The purpose of this paper is to assess challenges of
housing cooperatives and the impact on performances of the projects in Siltie Zone,
Southern Ethiopia. To achieve the intended objectives mixed design method is used. To get
primary data, 111 questionnaires were distributed to engineers working in urban
development and construction department, contractors and housing cooperatives. RII and
Kendall’s coefficient of concordance analysis techniques were applied by using MS Excel
and SPSS V-26. Analysis result has revealed that the top five construction phase challenges
are stemmed: fluctuation of construction material price; absence of options to get and
manage financial shortages from financial challenge clusters; and absence of local financial
initiatives; lack of access to infrastructural services; problem of similar design schemes and
rigidity from institutional challenge clusters are identified as critical factors. Also, results
unearthed that impact severity of construction phase challenges on cost and time
performance is as severe as high. Specifically, impact severity of financial challenge clustertechnical specifications and cost should be properly prepared; mobilizing resources at right
time; and hiring competent labor and contractor are the top four mechanisms to improve
construction phase performance of housing projects. From the results special attention to
housing program by government is recommended as the basic and central to solve the
aforementioned construction phase challenges. The results may enable construction project
managers, designers, contractors, local government and policymakers in broad to be
integrated on enhancing construction phase performance of housing cooperatives in the
study area and elsewhere similar to this study.
