“FEASIBILITY STUDY OF AFFORDABLE MODELVILLAGE AT RILIMA IN BUGESERA district

Abstract

This project report entitled “Feasibility study of affordable model village of G+2 at Rilima site in Bugesera district” was designed to provide model village layout which is Rilima site and affordable to be implemented by Bugesera district. This study was done for the purpose of conducting the Geotechnical study, architectural and structural study, topographic study of Rilima site, bills of quantities and environmental impact assessment. To achieve the above objectives, different methods and material have been used. Geotechnical study conducted by site visit and conducting dynamic cone penetration test (DCPT) and the preferable bearing capacity of soil is 3.47Bar at 80cm penetration depth. Architectural drawing provided are three G+2 apartments, health post, bank, 12 classrooms, minor market, Playgrounds and two car parking area by using Arch card 24. Structural study included are designed of slab, beam, column and footing (here the most critical members are designed and the findings are applied to all related members) This was done by referring to British standards design procedures of structural elements and soft wares (Arcad and prokon) to determine maximum bending moment and shear force. Topographic study was conducted by site investigation and software (arch GIS) and result gives that Rilima site is somehow plane site which means that it is not too sloped. Environmental impact assessment(EIA) was done by documentation referring to be lows of conduct established by the government of Rwanda for the wellbeing of Rwandans. In this phase positive impact of project were observed and negative impact were found with their respective mitigation measures. The results after analyzing show that the reinforcements for slab have been found to be T10@300mm in long direction and T12@250mm in shorten direction of slab and no links required due to shear resistance is bigger than shear stress, beam reinforcements was found to be 7T12 maximum applied moment=90.38KNm, ultimate shear force(v)=123.69KN and links are T6@248mm. The steel reinforcement of column was 5T12, for turning ramp steel bar of T10@300mm was found while for and foundation reinforcements was found to be T16@75mm in both direction of the footing. The soil bearing capacity is equal to 3.47 Bar. As Rwanda housing authority(RHA) ordered all 30 Rwanda’s districts to house people who live in high risk zone and those who are not owned to land for accommodation. In line with government policy to work on the feasibility study of Rilima affordable model village and show its positive impacts and negative impacts with their mitigation measures t in Bugesera district especially the population of Rilima and their surroundings. It was concluded that the design of a Model village was a very careful task to accomplish because it includes many services (apartments, classrooms, health post, bank and minor market) which require great attention and enough time to accomplish. Every structural member was designed at their most crictally loaded areas to provide maximum safety and service ability of such dwelling buildings. The result of geotechnical study shows that the capacity of sub soil is capable of resisting the ultimate applied load. It was recommended to: Bugesera district possibly implement this designed project with any additional design other than that conducted, in this project. To ULK Polytechnic institute to increase the organized field visits for getting tangible knowledge and skills for linking the class trainings and the and reality on the field for the purpose of having qualified graduates with greater practical design skills. Future students of ULK Polytechnic institute to put more effort in studying civil engineering software because they are its base.
