Abstract
The perception of quality is different among every individual. The perception of construction
quality is different among all construction professionals. Construction quality is a big issue
in the construction industry. Quality in construction is of utmost importance for sustainability
of any construction project. Factors that affect quality in construction project must be
identified for improving quality in construction project. So, this study examines the
perception of Client, Consultant and Contractors, regarding the quality and factors affecting
quality in building construction projects in the Kathmandu Valley. Through a mixed-
methods approach involving questionnaire surveys, Key Informant Interviews (KII), and in-
depth interviews (IDI), the study identifies promising perception on construction quality and
key factors that affect construction quality in building construction projects. In conclusion
this study proposes probable measures to improve quality in construction in both private and
public sector projects.
A total of 57 respondents, including clients, consultants, and contractors, participated in the
study, providing insights into their perspectives on construction quality and factors that affect
quality in building construction projects. The findings reveal differing priorities between
private and public projects, with private projects emphasizing operational efficiency and
profitability, while public projects prioritize regulatory compliance and stakeholder
expectations. Spearman's Rank Correlation Coefficient analysis indicates varying levels of
agreement among stakeholders regarding factors affecting quality. While there is some
alignment between clients and consultants, as well as clients and contractors, significant
differences exist between consultants and contractors, highlighting potential challenges in
addressing quality concerns collaboratively. The study underscores the importance of
establishing clear quality control processes, with stakeholders unanimously recognizing the
need for robust quality management systems, training programs, and rigorous inspection and
testing procedures. Insights from KII and IDI further emphasize the importance of
documentation, feedback mechanisms, and continual evaluation to ensure sustained
improvement in construction quality.
