oa Journal of Construction Project Management and Innovation - A comparison of construction related rework in Uganda and Mozambique

 

Abstract

The realisation of the expected minimum client quality requirements in both the products and processes in the construction industry remains challenging. The effects have been increased wastage and value loss through rework in both public and private sector initiatives providing social services in developing countries. The purpose of the research was to compare the impact of construction related rework on project budgets and schedule in public building construction in both Uganda and Mozambique, being examples of developing countries. The objective of such comparison is to document where focus should probably be placed in ensuring that quality requirements in construction are achieved. Case study approach was adopted and separate case study protocols prepared. The scope of study in the Ugandan project involved construction of classroom blocks, health centres and staff housing between 2008 and 2011. The scope of study in the Mozambique project involved the construction of 209 public housing units in Mozambique. The units of study were rework-related project budget and schedule overruns with further comparison of rework-related impacts on both project budgets and schedules under study. In Uganda, the mean percentage rework range was 12.45% - 15.58% of the construction contract scope. It was determined that the mean percentage of rework-related impact on project budget and schedule was 4.53% and 8.42% respectively. In Mozambique, the mean percentage rework range was 3.35% - 4.40% of the construction contract scope. It was determined that the mean percentage of rework-related impact on project budget and schedule was 0.56% and 12.0% respectively. Acknowledging the differing cultural contexts of both countries where the study was conducted, these findings could improve governance and strengthen the regulatory framework on quality management in both Uganda and Mozambique.
