Assessing the Quality of Construction work and the impact of unverified construction materials (sand and aggregates) on quality of privates buildings in Adama city

Abstract

The quality of the performance of any construction project is determined to achieve the intended purpose of the project. In order for this to happen, the stakeholders involved in the construction and the materials used for the construction are crucial. The researcher have tried to see if the necessary construction process and the following two important points are being followed on the buildings being built by private investors in Adama city. The main thing the researcher saw during this time was that many buildings were being built by private investors in Adama. So the researcher confirmed whether the buildings under construction are undergoing the necessary construction process or not.and also the researcher verified that the materials used for construction are being tested for quality and that they are being used for construction and also the researcher researched these points by asking the first and second objectives in the form of questioner and the third objective is to determine what the materials used for construction are determined by testing them in the laboratory. The main reason for looking at and answering these questions is that most studies in the past have focused on how to maintain the quality of construction, not on individual buildings but on public buildings. To this end, the researcher used descriptive research methods to evaluate the quality of construction and to assess the involvement of government bodies in private construction projects, and the researcher used causality research methods to assess the impact of unproven construction materials (sand and gravel) on private buildings.According to my research in Adama the government has issued a construction proclamation, but it is not being implemented properly. Also, most builders do not hire a registered contractor or consultant. In general, the buildings under construction in the city are in dire straits in terms of the quality of construction, the involvement of government bodies as authorized by the proclamation, and the quality of construction materials. Therefore, the parties concerned with the problem of each building, whether the building owner or the building authority, are recommended to use the solution set by the researcher.
