onstruction defect can be defined as a fault in design, the worship and material system which leads to project failure.

Generally, defects occur as a result of failure to follow required guidelines resulting to
financial, property and personal damages as argued by Robson, (2015). Construction defects
are usually hard to identify since only experts can analyze when a procedure is not correctly
followed (Waziri, 2016).
Types of construction defects
Design defects
Errors in designing

Design defects occurs when engineers and architects make errors when
planning on how facilities are going to be constructed. The most likely losses
errors that might occur includes the water penetration plan, poor draining
system design and inadequate structural support leading to occurrence of
(Cogurcu2015).

Workmanship
Source:(Levelset,2018)
Material defects occurs when inferiorproducts are
used during the construction. The material used in
construction projects is based on the requirement of
the end products. the higher the quality of the end
product, the higher the material quality that should
be used. The use of inferior products means that the
buildings and infrastructures cannot last for long
period ((Tayeh, et, al, 2017)
The interpretation of designs is important for the safety of the
occupants and users of buildings. Workmanship is a scenario
where construction is not undertaken as per the directions of the
designers. It results from misinterpretation of designs and pans
leasing to poor quality of buildings (Bagdiya&Wadalkar,2015)

How defects lead to wastages in the construction industry
Effects of defects in construction
Source:(LMT,2018)
In construction works, defects must be corrected otherwise, they might lead to greater losses in
future. The wastage in defects comes as a result of additional work that needs to be performed to
correct defects that are noted.
Financial wastages
Financially, organizations are forced to use more funds to undertake repairs as a result of additional
work to mend the effects of defects. Since projects are run under strict budgets, there is need for
project managers to ensure that the actual expenses do not exceed the budget. However, it is
difficult for project managers in construction project to ensure that budget is actualized since more
resources will be allocated in order to amend the defects.
Human resource wastage
In terms of human resources, organizations are made to committee more employees for repairs as
opposed to using the employees in undertaking other important stages of the projects. In presence of
defects in construction projects hence means that employees will be used to undertake repeat tasks
rather than undertaking progress tasks and advancing the projects (Dey, et al., 2017).
Time wastage
Construction projects are undertaking in consideration with a time plan. This means that project
managers are required to follow the project plans in order to deliver each milestone at the right
time. However, the presence of defects in the projects is likely to lead to delays in the process of
project management (Gulghane&Khandve, 2015). Since defects have to be solved immediately,
they are realized, time is used when trying to redo the work. This leads to time wastage and project
delay. Milestones cannot be reached at the required time since employees have to concentrate in
amending the defects to reduce risks of losses and accidents upon completion of the project (Tejale,
