Beside to this the quality of construction material, sanitary and electrical fittings and improper installations. To alleviate this problem special attention is taken in designing process. The proposed typology is designed considering economy, safety and aesthetic values. Since we used common walls, common stairs, agro stone partition wall, energy saving lamps such as fluorescent and compacted lamps the designs are economical and cost efficient. From this project the lesson we learnt are the following: it improves the knowledge and skill of structural design, architectural design, electrical installation, sanitary design and computation of bill of quantity. It helps us to acquire knowledge through discussion, referring different books, consulting our advisors, familiarizing with EBCS (Ethiopian Building Code Standards). In addition to this familiarize with different software’s such as Arch cad, AutoCAD, SAP and ETABs. The project covers the majority of the courses which are in the curriculum. It helps us to revise the previous courses and to aqua ire fundamental knowledge. So, the project should continue as it is. Page 11
