Title: Factors influencing construction quality in Ghana: Comparison of designer’s and contractor’s perspectives
Abstract: In the construction industry, projects are mostly anticipated to establish an equilibrium amongst
project time, cost and quality. Achieving quality when carrying out construction project is the
ultimate objective among others to every stakeholder. Quality of construction execution plays
a crucial role in determining the acceptance of construction project by clients and resultant
contractual payment levels. This has enlighten construction industry stakeholders to be
conscious of quality as a relevant objective in attaining client satisfaction and achieving
competitive advantage. In this thesis, by gathering relevant research findings, aims to
investigate factors influencing construction quality in Ghana from perspectives of the designer
and contractor. Four objectives were set on which literature review was conducted which
includes: determining whether designers and contractors equally consider design quality
important in setting the overall quality of project, identifying the causes of poor construction
quality in Ghana, identifying whether there are difference in the perspectives of designers and
contractors on the causes of poor construction quality and identifying potential solutions to
improve construction quality. Quantitative method was adopted in which survey questionnaires
were administered to respondents to gather primary data obtaining a sample size of 52. The
analytical tool utilized was Descriptive statistics. The findings of the research indicated that
both designers and contractors equally consider design quality important in setting the overall
quality of project. Also, Out of the findings of the research conducted, it indicated that: Lack
of proper supervision from architects, Use of low quality materials, Change orders, Poor
communication among project participants and Poor planning and scheduling are the most
significant causes of poor construction quality. More so, it was established that Good site
working conditions with proper inspection, Constructability of design, Competence and
experience of project team members, Quality materials in construction and Efficient teamwork
and cooperation are the most significant potential solutions to improve construction quality. It
was recommended that designers must be encouraged to put in their best during the designing
stage of construction projects since design quality is important in setting the overall quality of
a project. Moreover, contractors must also be engaged in designing stage of project to
contribute to feasibility and constructability of project design.%%%%A thesis submitted to the Department of Construction Technology and Management,
