Abstract:
Completing projects on time is an indicator of efficiency, but the construction process
is subject to many variables and unpredictable factors. In analyzing delays, the common
used methodologies include time impact and as-planned expanded. The purpose of the
study was to assess the effects of scheduling delay analysis in construction projects a
case study in Ashanti, Brong-Ahafo and Eastern Regions of Ghana. The research
design adopted for this study was descriptive cross-sectional case study and exploratory
design using quantitative method. A purposive sampling method was used to select 80
respondents. Opinions of employees were solicited using a structured questionnaire and
interview. The data was analysed using Statistical Package for Social Sciences (SPSS)
version 20.Results from the study showed that the major objectives of scheduling in
construction projects in the construction industries include “to expose and adjust
conflicts between trades or subcontractors” and to “resolve delay claims”. The major
causes of construction delays include construction mistakes, followed by poor
supervision, poor coordination on site, changes in specifications, contract modification
and, as well as delayed payments. The results from this study also indicated that a
relationship exist between time analysis and project scheduling. It was revealed that
project scheduling was explained by 67.0% (R2= 0.67) of the variance in time analysis.
It was also revealed that construction delays explained the bulk of the variance in asplanned
projects (beta= .943, t=, p<.001).The results indicate that there was
significant correlation between delays and project planning. In conclusion, the study
revealed that scheduling in construction projects is important in finishing projects on
time within budgets and ensure customer satisfaction. Again it may be concluded that
time impact analysis has an impact on project scheduling and Construction mistakes
were the major causes of construction delays. From the study, it is recommended that
project should be finalised with all details before tendering the work. Clients should
allocate sufficient time and adequate finances for the design of the projects.
