RE: INTERVIEWS
As an endeavour to deliver adequate social housing to under privileged communities, simultaneously meeting National Building Regulations as set out, and ensuring their efficiency by NHBRC concerning the quality and well-being of owners of low-cost housing. This interview question is expected to get the knowledge and experience of Designer, Contractor and Inspector of the procedures and policies in use from inception to completion. This interview also intended to identify plans and strategies to make the Quality Assurance System effectively towards the delivery of low-cost houses. Construction is a multi-disciplinary industry involving different personnel from different departments with various skills, their inputs in this endeavour will assist the interviewer to; after completing conducting interviews and data analysis from the responses retrieved decide which mechanism is best to respond to quality concerns in low-cost housing. This interview is also anticipated to assist the interviewer in fulfilment of Master of Technology Degree in Construction Management (course) at Cape Peninsula University of Technology in the Department of Construction Management and Quantity Surveying. The title of the thesis is: “Analysis of the effectiveness of Quality Assurance Systems towards delivering low-cost housing in the Western Cape South Africa”. Acquiring procuring
Research Questions The research questions for the research are as follows:
Are the poor resultant quality problems still persistent in low-cost housing construction?
Which types of quality assurance systems are in practice in the delivery of low-cost housing?
Are the quality assurance systems assisting in the delivery of low-cost houses?
How can the system be implemented to achieve the objective of NHBRC of good quality standards?
What are the factors hindering the successful implementation of quality assurance systems in low-cost housing?
138
What strategies are put in place to ensure the complete implementation of quality assurance systems in low-host houses?
