Feasibility study of affordable G+2 model village at Rilima site 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, structural study, topographic study of Rilima site, 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 334.7KNm2 at 80cm penetration depth. Structural drawing provided are three stories 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 T7@12 and links are T6@248mm. The steel reinforcement of column was T5@12, 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
