FINAL INTERNSHIP REPORT 1. INTRODUCTION 1.1. General introduction An internship program offered 4th year engineering students is planned by Arba Minch university institute of technology, which forms the foundation for the development of capacity building and competitiveness of industries in the field of Engineering and technology. Moreover it can give students to develop their three and half year‟s theoretical background to practical one. This program takes one semester long time, starting from beginning of March to end of June. On this regard I was able to at look this internship program after I had successfully completing my three and half years academic study and holistic exam. After this I had applied for my hosting company (Berhanu Alemayehu building contractor), which is found in Addis Abeba, and I had accepted as they promised by the confirmation paper. The project was building of ground plus three (G+3) residential building. 1.2. Background of the company 1.2.1. Brief history of the Company As a full service general contractor Berhanu Alemayehu, building construction has grown dramatically since its establishment in 2006E.C. The company is established with purpose of providing various construction services like construction of buildings, foundations, and various types of civil engineering structures contributing to the development of the construction industry. Berhanu Alemayehu building construction is not fully equipped with machineries and tools in accordance with the applicable regulation of the federal ministry of works and urban development and has been participating in different region of Ethiopia. Rendering service of high quality, timelines and coast effective management schemes are principal concern.

FINAL INTERNSHIP REPORT 2. OVERALL EXPERIENCE In this section I tried to list the overall work what I had seen in my company, the process of getting the company, the section that I perform my task, work flow of the section and the detail expression of the site work. 2.1. How I get in to the company After I finished the first semester of the 3rd and half year courses and completed the holistic exam, I was invited to take the internship program. Before I was employed to I delivered the letter which was given for me from my compass. And the company accepts my request letter and they gave their accepted letter for me, then after I submitted the acceptance letter which was received from the company to my department. After this I submitted the necessary documents to the company (BERHANU ALEMAYEHU GENERAL CONTRACTOR) which I received from my university. My supervisor gave me an orientation about the whole activities which will be done during my intern time. In addition to this he told more about the organizational structure of the construction company, the management level of the organization and the raw materials used or their resource and other related information‟s in the first week of the internship time. Moreover, he advised me what I have to see and what shall I do in four months internship period. Then I was investigating the construction site and saw what types of works were done in the site. When I was investigating the site, my supervisor told me new terms used by workers in the site. 2.2. Section of the company I have been working in On the company there were two working sections, office and site. But I was able to work at the site section, because there are a lot of activities in the site which are related with our classroom theoretical knowledge and it have no sustainable situation to see office work. 2.3. The workflow in the section In the project engineer work section there are three main working sectors and other assistance working sectors that play a great role in the success of the project. This is because in any construction project one section of work is highly dependent on another working section.

FINAL INTERNSHIP REPORT To have a good quality in any kinds of construction each member of the working section must cooperate and work together. The workflow is:

General Manager General for man Subcontractor

2.4. Site work In this section of my report, I will try to describe activities and practices that were done in my hosting company during my internship time. During my internship time I was able to see the practical works starting from excavation to some superstructure working. I used observation method as well as participate in all activities that have done in the site to achieve my task and to find out the practical knowledge. I will try to describe the activities in my intern time in to two parts:  Substructure working and  Superstructure working 2.4.1. Substructure works Sub structure is a part of the building located below the ground level. By the time I arrived at the site, the setting out had already been completed. Different parts carried out, these and other works include in this sub topic.  Preparation of the project site This is the first stage in construction work. At this stage the site is prepared as follows:  Clearing the site,  Dewatering if any water exist etc.

 Earth work Any work related with excavation, backfill, cart way of surplus material and the others which carried out in the site where the building/civil engineering project/ will be constructed is known as earth work. It‟s better to classify earth work in to the following major classes to deal with more:-

A) Excavation:-removal of soil from the construction site to specified depth to provide space for the intended work. Some of the main excavation types are listed below:1. Bulk excavation It refers to removal of huge amount of soil from the site to fulfill the structural requirements. Excavation to get reduced levels of every structural element below the ground level is called bulk excavation. Bulk excavation is required: To reduce the ground level to the specified depth for the foundation  When the topography needs a cut for the ongoing work  To achieve the required soil type which satisfies the specified bearing capacity 2. Pit excavation This excavation work for the purpose of footing is expressed as pit. In pit excavation the depth is decided by considering the depth that the sub structure, footing will be situated and its dimensions are based on the member dimensions and the working areas. Excavated materials may be reused for back fill or cart away to an appropriate tip. Pit excavation are in order when the soil stability is good, especially when there is no or low wall slide. If not, excavation of the whole area, bulk excavation, is recommended. In our site the soil is so stable that pit excavation was incorporated.
