Abstract:
Construction industry has complexity in its nature because it contains large number
of parties as clients, contractors, consultants, stakeholders, shareholders and
regulators. The total annual cost of worldwide project failures alone is $7.5 trillion
dollars. A report from the Ministry of Roads and Infrastructure identified eight main
reasons for the failure of government projects. These included inadequate planning;
insufficient buy-in by senior management; failure to engage effectively with key
stakeholders; a lack of technical skills; poor project monitoring and review;
inadequate initial evaluation of the project; poor networking skills; and failure to
integrate the disparate parties needed to deliver project success. Hence, this study
examined the relationship between project planning and performance of urban road
projects in Kenya. Specifically, the study focused on project design, scope planning,
project cost planning, and project risk management planning as the independent
variables. The moderating effect of road construction policy on project planning and
the performance of urban road projects in Kenya was examined. The study adopted
the project management theory, systems theory, queuing theory, resource-based view
theory, fuzzy set theory, and incremental theory. The study adopted descriptive
survey research design and positivism research philosophy while its target population
included 34 urban road projects in Kenya and 408 Construction registered
professionals within the urban road projects. Census sampling was used to select all
the 34 urban road projects whereas Yamane’s sample size determination formula and
stratified random sampling method were applied to arrive at a sample size of 202
professionals from the urban road projects. The unit of analysis was the urban road
projects whereas the unit of analysis was the construction professionals. Primary data
was collected through the administration of questionnaires to the sampled
professionals in the urban road projects. A pilot study was conducted to establish the
reliability and validity of the questionnaires. For reliability, the questionnaire had a
Cronbach Alpha value of 0.944. In this study, quantitative data was analyzed using
descriptive and inferential statistics. Descriptive statistics were summarized into
percentages, means and standard deviation. Data was processed using SPSS version
25 and the results presented using graphs and tables. Inferential analysis was done
using the correlation and linear regression analysis. The study revealed that
separately and when combined with other variables, project design, scope planning,
project cost planning, and project risk management planning had a positive and
statistically significant effect on the performance of urban road projects in Kenya.
Results also indicated that road construction policy had a positively significant
moderating effect on the relationship between project planning and performance of
urban road projects in Kenya. The study concluded that project design, scope
planning, project cost planning, and project risk management planning had a positive
and significant effect on performance of urban road projects in Kenya. The study
recommended that construction firms should invest in specialized training and tools
to improve model development, optimization, and visualization for more efficient
and accurate project planning. Additionally, they should adopt modern construction
technologies such as Building Information Modeling (BIM) and project management
software to enhance integration and coordination across all phases of project design.
