Abstract - Foundations are key element in construction
The failure of a structure may be due to poor design, faulty construction, overloads and foundation failure. The failure of foundation tends to the failure of entire structure, loss of life as well as economical problem. There are several factors contributing to the failure of the foundation, if overlooked or addressed unsuitably, such as, design error, improper soil investigation, fluctuation of ground water table, seismic loads, etc.
projects. Identification of foundation failures and providing necessary treatment is very important. Many foundation failures are due to inadequate protection to foundation soils, improper geotechnical investigation and design error, improper sequence of construction and water level fluctuation. This paper reviews different causes for distress of foundation and also discusses their solutions to overcome and prevent these failures in consideration with cost. The questionnaire survey was conducted to rate the factors that contribute to the problem/defects of foundation construction and cost effective remedial approach for foundation failure. The questionnaire survey was evaluated by Relative importance index method and analysed by Microsoft Excel.
2. OBJECTIVE The main Objective of the study is To identify the factor that contributes to the problems/defects of foundation construction field operation.
Key Words: Foundation failure, Distress factor, Cost effective remedial, Relative importance index method.
The aim of this research, investigate cost effective remedial approaches for different failure conditions of foundation.
1. INTRODUCTION
The study of safety aspects related to foundation in construction.
The main function of foundation is to transfer the loads from superstructure to, the underlying soil or rock over a large area at reduced pressure. It serves as an interface between superstructure and substructure. Generally foundations are classified as shallow foundation and deep foundation. A proper design of foundation system requires the following (i) purpose of engineering structures, possible service life loadings, various forms of framing, soil profile, construction approaches, construction costs, and clients/owner’s needs (ii) design without affecting environment and enough margin of safety with respect to unexpected events and uncertainty in determination of engineering properties of soil and satisfactory tolerable risk level to all the parties, i.e., public at large, the landlord, and the engineer.
3. METHODOLOGY The Main Objective of the study is Literature study Field investigation Preparation of Questionnaire Questionnaire distribution and collection Data Analysis Results and discussion
Additional contemplations that should be taken into account vary as per particular requirements and purposes, such as, foundation in extreme climate conditions, foundation on loose soils, foundations for different loading conditions like overturning, sliding or uplift, consideration for future expansion, production against corrosion or other injurious material present in soil, suitability with respect to local environment standards etc. It is well understood that engineering structures eventhough being constructed with suitable health and safety measures do fail or collapse.

The general procedure of this study depends largely on the survey questionnaire which will be collected from the various local building contractors of different places by mail or by online filling Google form. A thorough literature review was initially conducted to identify the factors that contribute to the problem/defects of foundation construction and cost effective remedial approach for different factors. Questionnaire survey – the data was collected through questionnaire survey delegated to contractors, consultants and clients that involve in management of construction project.
