    Assessing the Impact of Sustainable Construction Practices on Project Performance.
    (Kabale University, 2024) Niwahereza, Blair
    The purpose of this research was to assess the impact of sustainable construction practices on project performance. Questionnaire surveys were conducted across stakeholders that included site engineers, consultants and contractors. The research categorized the proposed strategies to the implementation of sustainable construction practices using relative importance index (RII) as a basis of analysis. The most commonly used sustainable construction practices were identified as; use of local materials, use of bio-degradable materials, use of recycled materials, prefabrication and water conservation measures. Out of the 56 respondents, 16.1% were familiar with prefabrication, 14.3% were familiar with the use of bio-degradable materials, 28.6% were familiar with the use of water conservation measures, and 8.9% were familiar with the use of recycled materials and 32.1% constituted to those who were familiar with the use of local materials. The relationship between sustainable construction practices and project performance was critically determined using regression analysis and project performance was basically based on time, cost and quality. The general response from both parties were analyzed, high scored mitigation measures were discussed; awareness and education should be implemented, innovation and technology adoption; industry collaboration and partnerships, certification and standards, performance monitoring and reporting, and providing incentives were identified as the most effective strategies in implementing sustainable construction practices on construction projects. Awareness and education was ranked first with RII of 0.875, innovation and technology adoption was ranked second with RII of 0.857, industry collaboration and partnerships was ranked third with RII of 0.811, certification and standards was ranked fourth with RII of 0.807, performance monitoring and reporting was then ranked last with RII of 0.725.

    Impact of Municipal Solid Waste Leachate on Surface Water Quality: A Case Study on Kabuturumba Stream.
    (Kabale University, 2024) Rubarema, Paul
    The purpose of this proposal is to investigate and study the impacts of solid waste leachate on surface water quality. A case study on Kabuturumba stream in Mbarara city. There has been an increasing contamination of surface water sources due to poor methods of waste disposal around Mbarara city and Uganda at large. This study was carried out in different seasons of the year where by samples were collected in dry season and wet season. Different pollution hotspots where also considered in the upstream before joining the stream to clearly understand their potential impacts these points included Coca cola outlet, pearl diary discharge stream and Lubiri stream joining Kabuturumba stream from Kisenyi via Makenke barracks. Different physiochemical and biological parameters were tested in the laboratory. like pH/EC, turbidity, BOD, TDS TSS, heavy metal, bacteriological parameters such the presence of Total coliforms fecal coliforms and E. coli. Different parameters such as COD and BOD levels were found to be extremely high than the environmental standards but later on the hypofiltration or the cleansing capacity of the wetland around the stream helped on reducing them down the stream and almost reached the environmental standards, nutrient levels such as phosphates and Nitrates were also above the recommended values, bacteriological status was extremely higher and later on reduced downstream. The results indicate a level of surface water pollution and toxicities of these pollutants and their threat to human health. The seasonal effects were manifested in that the levels of pollutants increased in wet seasons as compared to dry seasons, this could have been caused by increased surface runoff during wet seasons. The study also indicates that some parameters and pollutants were affected by distance from the dumpsite while others were not.
