Introduction
Scope:
The scope of the study will cover how to avoid or minimize defects in
construction projects. The study is needed to apply those defects
concepts in planning, scheduling, and field operation. As India
developing country this study is essential to develop future
infrastructure on an economical basis. So that it will contribute to the
importance of growth rate potential and increase the competitiveness
of the economy.
Objectives:
To identify the factors responsible for the defects in construction.
For each important defect identified, the contributions of sources or
causes are to comp.
To work out remedial measures on causes under consideration to
minimize post-construction defects

Conclusion:
Defects found in flooring and external wall occur greatly (widely) in
Flats. While the percentage of defects occurring in flooring and
external wall in flats are the same and appearing in large percentage
is 18.35% in flooring and 17.7% in the external wall. The main reason
behind this may be because many services are done here. So special
care should be taken during the construction stage for these building
areas.
Recommendation:
From the above conclusions, it can be observed that wetted areas
are more prone to defects so it is recommended that these areas
should be given more attention during the construction stage, also
the use of good quality materials, as well as skilled supervision, must
be provided. So, a five-step process for managing the construction
defects is suggested and they are as follows,
•
•
•
•
•
Awareness
Investigation
Discovery
Evaluation
Treatment or remedy
This process can be termed as the life cycle of the investigation and
resolution of a construction defect issue
