Item Restricted Design and Construction of a Pneumatic Vibratory Conveyer.(Kabale University, 2024) Kalagala, AbdulbastTea, an aromatic beverage, is made by steeping hot water over cured or fresh leaves of Camellia taliensis. Typical tea processing stages include withering, rolling, oxidation, sieving, and firing. This project focused on designing a pneumatic-powered vibratory conveyor specifically for sieving tea leaves at the Kigezi Highland Tea Factory, Kabale branch. Vibratory conveyors are durable systems used to transport or sieve materials ranging from fine to coarse grains in workshops or factories. The project aimed to create a pneumatic-powered vibratory conveyor for industrial settings, offering lower power input and higher load capacity than traditional electric vibratory conveyors. At Kigezi Highland Tea Factory, the existing electric conveyor faces challenges, such as limited load capacity and high power consumption, which this design addresses. The new conveyor is designed to handle up to 25 kg, significantly more than the current 6 kg limit, and reduces energy consumption through pneumatic power. The system features a motor-driven single-stage compressor that supplies compressed air to two vibrators on the conveyor trough, enabling material transport and sieving. Designed for transferring and sieving tea leaves, the conveyor’s large trough surface allows for increased load capacity and enhanced sieving efficiency. Design methods included AutoCAD for 2D illustrations and sizing, MATLAB for calculations and vibration analysis, SOLIDWORKS for 3D modeling of the trough, frame, and components, and ANSYS for system analysis.Item Restricted Assessing the Effect of Different Particle Sizes of Coarse Aggregates on Concrete Properties.(Kabale University, 2024) Ahabwe, ReinhardConcrete's compressive strength represents the hardened concrete's capacity to resist compressive loads without cracking or deforming. Duff Abrams found that concrete strength largely depends on the water-to-cement ratio. However, other factors, such as cement strength class and fineness, concrete age, curing duration, admixtures, and aggregate properties (including size, shape, texture, and strength), also significantly impact compressive strength. This study investigated how varying particle sizes of coarse aggregate affect concrete properties. Results showed that compressive strength at 28 days increased as the size of coarse aggregates decreased, with strengths recorded at 25, 23.3, 21.5, and 19.7 MPa for 10, 14, 20, and 28 mm aggregate sizes, respectively. This trend is attributed to denser packing and stronger bonding among smaller particles. Additionally, workability was found to increase with larger aggregate sizes, with slumps measured at 76, 81, 87, and 98 mm for 10, 14, 20, and 28 mm aggregates, respectively, due to larger aggregates having a lower surface-to-volume ratio, which reduces contact between aggregate particles and the cement paste.Item Restricted Design and Analysis of a Hydraulic Scissor Lift Trolley.(Kabale University, 2024) Katwesigye, WilfredThis project focused on designing and analyzing a hydraulic scissor trolley to address the safety hazards and inefficiencies associated with manually handling heavy food sacks in warehouses and food stores. Current practices often involve workers climbing trailers using makeshift wooden stairs without guardrails, creating serious risks of falls and injuries. To improve safety and efficiency, the hydraulic scissor trolley offers a secure and ergonomic solution that minimizes injury risks while boosting worker productivity and operational flow. Powered by hydraulic fluid that drives a cylinder, the scissor lift allows for vertical movement of the platform. This project provides a comprehensive overview of essential components, such as hydraulic cylinders, scissor arms, and the base structure. Materials were selected for optimal durability and strength to withstand operational demands. Engineering sketches detail component dimensions, supported by static stress analysis performed using advanced software like Ansys and SolidWorks. The analysis includes calculations for lift height and additional lifting range, illustrating how this innovative design enhances safety and optimizes material handling in food storage facilities. By implementing this solution, the project aims to reduce delays and bottlenecks, thereby increasing overall productivity in warehouse operations.Item Restricted Investigating the Effect of Coffee Husk Ash as Partial Replacement of Cement in Concrete C-15.(Kabale University, 2024) Ainembabazi, EdinaThis study explored the impact of incorporating Coffee Husk Ash (CHA) as a partial substitute for cement in concrete, aiming to lower costs and provide a sustainable disposal option for agricultural waste. CHA, obtained from the combustion of coffee husks, was added in varying proportions of 0%, 5%, 10%, and 15% by weight of cement, with a mix ratio of 1:1.5:3 and a water-cement ratio of 0.6. Compressive strength tests were performed at 7, 14, and 28 days of curing. The findings revealed that compressive strength increased with the addition of CHA up to 5%, in comparison to the 0% control sample; however, strength decreased significantly beyond this point. Consequently, it is advised to use CHA as a partial cement replacement at a maximum of 5%, as this not only improves compressive strength but also provides environmental advantages and lowers the costs associated with concrete production.Item Restricted Design of An Automobile Engine Stand.(Kabale University, 2024) Turyasingura, CosmasThis report outlines the design of a light-duty engine overhaul stand aimed at enhancing maintenance practices for light-duty engines by offering a specialized platform for efficient overhauls. The main goal is to improve maintenance efficiency by reducing the time and effort needed for engine servicing. The design features thorough analyses, material selection, and detailed drawings for both individual components and the complete assembled stand. Key elements of the stand include a handle, upright, baseplate, front leg structure, central beam, rear leg assembly, casters for mobility, a dedicated mounting arm, pins, and various bolts for secure fastening. Stress-strain calculations from the design analysis demonstrate that the engine overhaul stand can safely accommodate the intended medium load during maintenance, ensuring reliable operation. The cost-effective design emphasizes the use of readily available and affordable materials, making it advantageous for small and medium-sized garages, as well as some larger ones, due to its simple fabrication process. By utilizing this stand, garages can enhance their engine maintenance practices to align with international standards, ultimately improving operational efficiency. This improvement can lead to quicker service turnaround times, reduced costs, and increased customer satisfaction. For smaller and medium garages, the stand’s affordability and ease of production make it a practical option, enabling a more professional and efficient engine overhaul process. Although larger garages may already have dedicated stands, this cost-effective design presents a viable alternative for expanding service capabilities or replacing outdated equipment. In summary, the adoption of this engine overhaul stand has the potential to enhance maintenance practices across various garage sizes, positively influencing the overall efficiency and service quality within the automotive industry.Item Restricted Design and Pro-typing of an Electronic Coil Winding Machine.(Kabale University, 2024) Arinaitwe, JoelFrequently, putting the driven equipment back in service is the highest priority, and users have made their decisions based on speed and initial cost. In the past, electrical power was very inexpensive, so managers were not concerned if the rewound motor was less efficient and cost more to Industries. Though method used to do motor repair in industries is motor rewinding which is a way of repairing spoilt motors in the industries which quite as few experienced technicians in charge and it takes a long period of time to carry out a motor rewinding process. This project introduces an electronic coil winding machine that addresses these limitations. The machine will employ an encoder, a rotary sensor that translates rotational motion into electrical signals. This allows for: Precise Control: The encoder data can be used by a control system to precisely regulate the speed and direction of the winding spindle, ensuring consistent coil geometries. Accurate Counting: The encoder pulses directly correlate to the number of wire rotations, providing a highly accurate measurement of the number of windings. Data Recording and Analysis: The encoder data can be logged and analyzed to monitor the winding process, identify potential issues, and optimize machine parameters for different coil specifications.Item Restricted Improving the Properties of Non G30 Soil for Use as Subbase Material with Tea Production Waste-Lime Blend.(Kabale University, 2024) Baluku, BennetThis research examined the potential of enhancing the engineering properties of non-G30 soil from Kabale Municipality for use as subbase material by stabilizing it with a mixture of lime and tea production waste. The study aimed to identify the optimal blend that improves the soil's strength and work-ability while adhering to G30 specifications. Lime was combined with tea waste, an organic by-product of tea processing, to assess its effectiveness in modifying key soil characteristics such as the California Bearing Ratio (CBR), Maximum Dry Density (MDD), Optimum Moisture Content (OMC), Liquid Limit (LL), and Plasticity Index (PI). Various replacement ratios of lime and tea waste were analyzed: 3% (2% lime, 1% tea waste), 5% (3% lime, 2% tea waste), 7% (4% lime, 3% tea waste), 9% (5% lime, 4% tea waste), and 11% (6% lime, 5% tea waste). The results indicated that the optimal stabilization was achieved with a 5% to 7% blend, where the soil met the required CBR, CBR swell, LL, and PI values, making it suitable for subbase use. However, higher amounts of tea waste led to reduced CBR and increased LL, highlighting the importance of balancing the organic content. The study concluded that using a lime-tea waste blend offers a sustainable and cost-effective approach to improving non-G30 soils, particularly in regions like Kabale Municipality, where tea waste is readily available.Item Restricted Design and Simulation of Power Quality Improvement System for Low Voltage Distribution Networks in Uganda.(Kabale University, 2024) Arinde, FrancisThe design of reliable power filters that mitigate current and voltage harmonics to meet the power quality requirements of the utility grid is a major requirement of present-day power systems. In this project, a detailed systematic approach to design a universal active power filter for power quality enhancement is discussed. The detailed universal active power filter shall be designed and simulated for balanced nonlinear loads using MATLAB/Simulink. The simulation results are intended to indicate that the proposed filter can minimise the harmonic distortion to a level below that deployed by the institute of electrical and electronics engineers (IEEE) standard, which say that THD in a network should not exceed 5%.This project focused on enhancing power quality in low voltage distribution networks at the point of common coupling (PPC) through the design and simulation of a universal active filter system. By combining shunt and series active filters, this hybrid approach addresses both current and voltage distortions, including harmonic currents, reactive power, voltage sags, and swells. [1] The effectiveness of proposed system will be validated through detailed simulations using MATLAB/Simulink software. The goal is to provide a comprehensive solution that improves power quality, protects sensitive equipment, and enhances overall system efficiency.Item Restricted Numerical Investigation on the Effects of Embedding PVC Pipes in Reinforced Concrete Beams.(Kabale University, 2024) Ampaire, ComboniThis study focused on how embedded PVC pipes affected the way reinforced concrete (RC) beams behaved. One of the six 300x300x3500mm beams that were modeled in Abaqus was solid, and the other five (B-25.4mm, B-50.8mm, B-76.2mm, B-101.6E50mm, and B-127E100mm) had different pipe sizes and locations. The material properties both elastic and plastic were assigned to the models and also contained concrete damaged plasticity (CDP) material qualities to effectively forecast failure processes. A concentrated load of 500KN was loaded onto the modeled beams and treated as simply supported. In addition, meshing was finished, with reinforcing meshing with global mesh with a global size of 100mm and concrete elements assigned to element type C3D8R hexagonal elements. After the analysis was turned in, the results were compared to those of a solid beam, including stresses, strains, the load-deflection ductility index, and crack patterns. The results indicated that the stresses in the bottom reinforcement and concrete increased as the pipe size grew. Furthermore, the ductility index and loading capacity declined with changes in pipe placement and size. Therefore, the location and size of the pipe affect the strength, stiffness, and ductility of the reinforced concrete.Item Restricted Design and Simulation of a Solar Thermal Dryer for Fruits.(Kabale University, 2024) Amanya, SylusThe write-up presented in this report focused on the design and manufacture of a solar thermal dryer for fruits that dries 5Kg of fruit slices, 5mm thick per batch, and can be used for small-scale farmers that grow fruits in western Uganda following a challenge they face like pests and disease infestation during open sun drying, nutrient loss and among others. The designed dryer aims to improve food security and reduce waste since there will be reduced post-harvest losses allowing people to preserve fruits for longer periods. More so, there will be economic empowerment and income generation as it will necessitate shelf-stable products that can be stored and sold thus generating additional income. The main objective was to design and manufacture a user-friendly solar fruit dryer that utilizes minimal effort and harnesses the power of the sun to dehydrate various fruits into tasty chips. This was guided by three specific objectives i.e. to conceptualize the design of an efficient solar thermal system for drying fruits, optimize the drying efficiency by creating a controlled airflow system, and evaluate the performance of the proposed dryer through simulation. The methods used in carrying out this project included library search, internet search, and brainstorming of different ideas. By reviewing the design parameters of other already established related designs, the conceptual design was formulated and developed in SOLIDWORKS. The design of major components was carried out while others were selected. Steady-state thermal and fluent analyses were performed with the help of the ANSYS workbench 2024 R1 software to study the behavior of the absorber plate, solar collector, and trays.Item Open Access Investigating the Effect of Seasonal Variation on Road Traffic Accident Occurance Along Selected Routes in Western Uganda.(Kabale University, 2024) Kwesiga, IvanThe study examined the seasonal variations in Road Traffic Accidents (RTAs) along Kabale Katuna, Kabale-Kisoro and Kabale Mbarara highway, western region, Uganda from 2018 to 2022 and explored the relationship between RTAs and seasonal changes and the effect of seasonal changes and road traffic accident on accident causalities on the routes. Secondary data on RTAs and mean monthly rainfall were collected for the period covered by the study from the Uganda Traffic Police Force and the Uganda National Meteorological Authority, Kabale Meteorological Station. The Analysis of Variance (ANOVA), and simple statistical techniques of frequencies and percentages were used for the data analysis. Correlation models were also used to explain variations in RTAs and to assess the degree to which the variations in RTAs were associated with the monthly rainfall. The study found out that there were 109 minor, 178 serious and 42 fatal accidents in the dry season and 121minor, 152 serious and 47 fatal accidents in wet season for the study period of 2018-2022 The study also revealed an increase of 0.77% of total traffic accidents during the Dry season. The number of RTAs and road injuries during the study period increased by 2.47% (n=133 to 149) and 4.12% respectively while death due to RTAs increased by 4.65% (n=23 to 29) from 2018 to 2022 and further revealed an increase of 0.77% of traffic accidents during the Dry season for the study period. Weak negative correlation (-0.049, -0.18 and -0.275) for the Wet season in 2021,2022 and (-0.275) for dry season of 2019 respectively, correlation between rainfall and accidents along the route during the study period is generally negative in wet season and positive in dry season. These indicate that weather is also a factor contributing to the recorded RTAs in the study area. However, the month of December and January had a highest number of registered road accidents which was associated with the higher volume of road traffic as people tend to travel more. It was concluded that there is no positive relationship between rainfall and Road traffic Accident but rather rainfall has a slight static significant on Accident Causalities due to weather changes and reduction of sight distance.Item Restricted Performance of Sisal Fabre as Natural Geotextile to Reinforce Soil Layers on Unpaved Road.(Kabale University, 2024) Kyomugasho, LilianNatural geotextiles are strong synthetic fabric usually used in civil engineering construction projects such as high way that stabilizes loose soil. Geotextiles may be used to improve; the embankment stability against bearing capacity failure, stability against slope failure through the foundation, allow a more controlled construction over very soft or difficult foundation soils. And sisal fibre is the one of the most widely used natural fibre and is very easily cultivated. The soil sample was obtained from Nyamkana road in Ntungamo district and the laboratory tests were carried out at Mbarara Regional laboratory. The tests carried out included; field density compaction, maximum dry density and California bearing ratio. The main objective was to investigate the performance of sisal fibre as a natural geotextile to reinforce the soil layers on unpaved roads so that we solve the problem of developing potholes, rutting, corrugation, weak subgrade resulting into mud formation, poor drainage system, non-uniform narrow width, stoniness, and environmental pollution from dust during dry seasons, rapid gravel loss, and these all together have increased regular maintenance costs. The study was limited to some soil tests on subgrade materials, to achieve the objectives, the study undertook the following methodology, particle size distribution, atterberg’s limit, maximum dry density test and testing CBR in the laboratory. The findings relating to these laboratory tests include: The liquid limit was 38%, plastic limit was 21%, plasticity index 17%, MDD was increased from 1.829 to 1.849Mg/M3 and CBR values using 60,30 and 10 blows increased from 3.7% to 9.2%,6.9%, 5.2%after the application of sisal fibre after the second, third and fourth layers of the soil compared to the CBR values without sisal and particle size was obtained and the clay soil was classified as silty or clayey grave sand and soil sample fall under group classification of A-2-6. Finally, it was observed that placing sisal fibre after the second layer gives the highest CBR value and MDD values. Based on the results the expansive soil reinforced with sisal fibre at the second layer can be used in unpaved road layers since it gave an increase in CBR from 3.7% to 19.2% since it meets the requirement as per the Uganda ministry of works, Housing and communication, 2005 and the general specification for roads and Bridges. Further research should be conducted to assess the long-term performance of sisal fibres and its performance under different weather conditionsItem Restricted Investigating the Efficiency of Coffee Husks in Bio-Retention Model for Storm Water Treatment.(Kabale University, 2024) Musasizi, JosephA bio-retention is the storm water Best Management Practices (BMP) designed to capture and treat the runoff using the natural properties of soil and plants to remove contaminants. Storm water from rooftops, paved areas, bare soil and sloped lawns transports eroded soil, animal wastes, litter, salts, pesticides, fertilizers, oil and grease and other potential pollutants which flows directly into the streams and rivers. This spoils the stream water quality and thereby causing a decline in aquatic biota. However, the selection of appropriate media structure and optimized design have not been adequately researched. Additionally, the applicability of bio-retention systems has not been introduced and implemented in Uganda. Therefore, this study is aimed at investigating the efficiency of bio-retention system in the removal of storm water pollutants using coffee husks. The physical bioretention model of four Columns: J, M, N and P of 102 mm diameter and 1050mm height was developed. The layers of filter media arranged as described in table 3.2 in chapter 3. The coffee husks were introduced into columns M, N and P in varying depth leaving J as control experiment (traditional sand filter bed). Materials used in the media structure were analyzed to meet the standards according to the bioretention design manual. The quality parameters of raw stormwater composite sample were determined before passing through the model and after passing through the model at different intervals i.e., at 0, 5, 10, 20 and 30 days after introducing the coffee husks into the model. The parameters tested were Temperature, pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Total Coliforms (TC), Faecal Coliforms (FC) or E. coli (EC), Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Oil & Grease (OG), Chlorides, Sulphates, Phosphorous, Turbidity and Colour. The results of the study showed that the bioretention column P drastically improved storm water quality at 30 days by reducing values of Faecal Coliforms, Total Suspended Solids, Total Coliforms, Biological Oxygen Demand and Nitrates as compared to the tested raw storm water composite sample except Colour.Item Restricted Investigating the Suitability of Partial Replacement of Basalt with Scoria as a Base Course Material for a Flexible Pavement.(Kabale University, 2024) Wambei, AllanThis study aims at evaluating the applicability of Scoria gravel as an alternative base course material in flexible pavements through blending with Basalt by modifying the physical and mechanical engineering properties of scoria. They are two types of scoria in Uganda with probably different properties that is black and red Scoria. In this case, Red scoria was used. This scoria was obtained from Kisoro district at the slopes of mt. Muhabura while basalt was obtained from Ntungamo district in Karegyeya. The material was taken to Mukono where it was tested from. Non-Probabilistic sampling techniques and experimental methods were used. To achieve the objectives of the study, the laboratory tests were passed in three steps. First, the Engineering properties of materials were independently tested; the results proved the marginality of red scoria gravel yet basalt showed suitable physical and mechanical properties. Second, scoria gravel was mechanically and physically stabilized in percentages by weight increments of 5%, 10%, 15%, 20%, 40%, 50%, 60%, 80% and 100%. The fundamental tests required for the base course CRR class are plasticity index, particle size distribution, flakiness index, linear shrinkage and ten percent fines value according to the general specifications for roads and bridges of Uganda. According to the general specifications for roads and bridges works, (Ministry of Works, Housing and Communicatins, 2005), the minimum requirements for plasticity index, particle size distribution, flakiness index, linear shrinkage and ten percent fines value are non-plastic, within the specified upper and lower limits, below 35% (<35%), below 3% (<3%) and above 110 kN with a ratio of soaked to dry being greater than 75% respectively. Basalt, scoria and their corresponding percentages satisfied the requirements for plasticity index, linear shrinkage and flakiness index. 5%Scoria-95% Basalt and 10% Scoria-90% Basalt satisfied all the requirements for the base course as per the general specification of roads and bridge works. 15% scoria-85% basalt and 20% scoria-80% basalt did not meet the requirements for ten percent fines value but satisfied all the other requirements for the base course. The remaining percentages failed to meet the requirements for both particle size distribution and ten percent fines value test but passed all the other tests. The optimum percentage blend was obtained as 10% scoria-90% basalt. Finally, based on this study it was recommended to use scoria gravel as an alternative base course construction material.Item Restricted Investigating the Performance of Epoxy Concentrations in the Self-Healing of Concrete.(Kabale University, 2024) Manzi, Evans EvalistConcrete, a fundamental construction material, is susceptible to various forms of damage (cracking). Formation of cracks may result due to the shrinkage effects during curing and mechanical loading which deteriorate the concrete performance especially in terms of durability aspect. Traditional methods of repair often involve human intervention and significant costs. In recent years, the concept of self-healing concrete has gained traction as a potential solution to mitigate the impact of cracks and enhance the longevity of structures. Self-healing concrete by using bacteria as a healing agent had gained interest among researchers. In contrast, this research delves into the intricate relationship between epoxy concentrations and the self-healing capabilities of concrete, aiming to provide comprehensive insights into optimal concentrations and their implications for construction. The experiment involved varying epoxy concentrations, ranging from 0% to 15%, in concrete mixes. Critical parameters, such as slump, compressive strength at 28 days, and microscopic structure after crack induction, were meticulously analyzed. The objective was to understand how epoxy, known for its adhesive and cohesive properties, influences the mechanical properties and self-healing potential of concrete. The experimental setup aimed to simulate real-world scenarios where concrete structures may be exposed to external stresses leading to cracks. The results revealed a consistent decrease in slump as epoxy concentrations increased, indicating a reduction in concrete work-ability. Notably, the compressive strength at 28 days exhibited a fascinating trend. At 5% epoxy, there was a modest increase in strength, while the optimal concentration of 10% demonstrated a significant enhancement. However, concentrations beyond the optimum (15% epoxy) led to a decline in compressive strength. The experiment's pivotal phase involved crack induction to assess self-healing capabilities. At 10% epoxy concentration, the compressive strength increased after crack induction. Microscopic analysis further corroborated these findings, revealing signs of self-healing within the concrete matrix. This enhancement suggested a unique healing mechanism associated with the optimal epoxy concentration.Item Restricted Assessing the Effect of Partial Replacement of Fine Aggregates in Concrete with Iron Ore Tailings in Kigezi Sub-Region.(Kabale University, 2024) Musasizi, AllanThis study aimed to assess the strength properties of concrete produced using IOT as partial replacement of the natural sand as fine aggregates. IOT is a waste product of iron ore mineral that is abundantly available in some regions and has the potential to be used as a sustainable alternative to traditional fine aggregates. In this research, the mixture, C15, was designed with 10%,25%, and 50% of IOT, natural fine aggregates and natural coarse aggregates. Properties considered included: workability, unit weight and compressive strength. Test results indicated that in all cases, IOT concrete gave high compressive strength than the conventional concrete. In conclusion, this study suggests that IOT can be used as a viable alternative to partially replace traditional fine aggregates in the production of concrete with acceptable strength properties for structural applications in pavement and floor slabs. Further research should however be carried out to investigate the durability and performance of IOT-based concrete.Item Restricted Impact of Municipal Solid Waste Leachate on Surface Water Quality: A Case Study on Kabuturumba Stream.(Kabale University, 2024) Rubarema, PaulThe 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.Item Restricted Assessing the Impact of Sustainable Construction Practices on Project Performance.(Kabale University, 2024) Niwahereza, BlairThe 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.Item Restricted Establishing Empirical Relationship Between Project Scheduling and Project Success in the Uganda Construction Industry.(Kabale University, 2024) Mukisa, JohnMany building construction projects in the Uganda construction industry experience project failures in the sense of not being finished within the scheduled time frame, approved budget, and not meeting the quality standards as per the initial plan. The purpose of this study was to establish empirical relationship between project scheduling and project success in the Uganda construction industry. Questionnaires were administered to eighty four targeted respondents. Seventy three respondents were able to return them giving their opinions on the project scheduling practices commonly used in Uganda, their impact level and effectiveness in achieving project success. The data gathered were analyzed using statistical techniques with relative importance index and regression analysis as the bases of analysis. The study identified the project scheduling practices that are commonly used as Gantt chart (RII = 0.992), CPM (RII = 0.940), Resource Levelling (RII = 0.860), PDM (RII = 0.759), and PERT (RII = 0.622), while Agile scheduling methods (RII = 0.614), and line of balance method (RII = 0.296) are least used. This showed that Gantt chart, CPM, resource leveling, PDM, and PERT are the most suitable and widely used. The impact level of the practices was determined as Gantt chart (RII = 0.973), CPM (RII = 0.964), Resource levelling (RII = 0.901), PDM (RII = 0.792), PERT (RII = 0.658), Agile scheduling methods (RII = 0.627) and line of balance method (RII = 0.332). This indicated that Gantt chart, CPM and resource levelling had a very high impact level on building projects, being followed by PDM and PERT. The regression analysis determined that Gantt chart, CPM, and resource levelling were the most significant scheduling practices thus being the most effective in achieving project success. The study recommended that further research should be conducted to investigate the role of technological advancements and emerging trends in project scheduling, such as lean construction, Agile scheduling, and Building Information Modelling (BIM).Item Restricted Design and Construction of Underground Cable Fault Location and Notification System.(Kabale University, 2021) Mugisha, SimonThe overhead lines are mostly used when compared to underground cables though in towns and cities, underground cables are preferred. The underground cables are largely used in urban areas instead of overhead lines. This is because they have minimized transmission losses, can lead to death of human beings and destruction of property like buildings. This comes as a result of tall buildings being near the conductors. In determining the location of a fault point in the underground cable, the AC power in the cables is first switched off because they cannot carry both AC power and DC power at once and the standard concept of Ohms law is applied that is, when a low DC voltage is applied at the feeder end through a series resistors representing the cable lines, then current would vary depending upon the location of the fault point in the cable. In case there is a short circuit (Line to Ground), the voltage across series resistors changes depending on the fault location. This voltage is then fed to an Analogue to Digital Converter (ADC) to develop precise digital signal and the Arduino nano communicates the LCD screen to display the status of the underground cables by showing the fault location (distance) in kilometers with its respective phase.
