Practices adopted to the execution and quality control of foundations in building construction

The foundations are the elements of a building that have the function of transmitting the loads of the building to a resistant soil. A drawback of foundations is the difficulty of identifying execution failures upon completion, because their elements are buried. Therefore, these failures are often discovered only when pathologies arise in the building, such as cracks. In order to avoid the occurrence of failures in a building, it is essential that the engineer and his team have full control of the execution of foundations and the company has a strict quality control system. Thus, this article aims to conceptualize briefly the execution techniques of foundations applied in building construction and analyse their quality control. In addition, the procedures adopted by construction companies in terms of execution of foundations and quality control are evaluated through the case study of a construction of a multifamily residential project from a large construction company in the city of Rio de Janeiro, Brazil. In this construction were implemented three different types of foundation, namely: spread footings; steel piles; and micropiles. Finally, the main practices to be adopted by construction companies toward making the execution and quality control of foundations more effective are identified.
