2.3.1 What is snagging?

Snagging is a procedure used within
the construction industry to check newly constructed buildings for minor
defects and faults that have to be rectified by the developer or contractor.  Snagging is part of the procurement proceedings
in the construction industry and can influence the productivity and performance
of construction companies. Numerous factors that influence quality can be
connected to the design of the project and poor workmanship. Snagging includes
the correcting of errors and faults which includes ineffective work.  Therefore, the costs that apply to snagging should
be measurable for construction companies and contractors ( Sommerville, et al., 2004).

2.3.2 The Snagging Process

Sommerville & McCosh (2006) suggested that snagging methods are generally
focussed on checking properties for poor workmanship but, by its very nature
and complexity, the house building procedure frequently leads to minor defects
being identified in the finished product. Diagram
1 illustrates that the purchaser has very little input in the interpretation
of the functional requirements of the property or its quality standards. The
developer sets and manages the quality standards and, as diagram
1 illustrates, there are only two opportunities for rectifying defects prior to
the handover of the property (Sommerville & McCosh,
2006). Numerous
companies in the construction industry use a paper-based snagging procedure to
record and manage the snagging process. This paper-based method results in a
long and time consuming process where the recorded information has to be typed
up, scanned and copied in order to send information to the contractors who in
turn are responsible for correcting the defects ( Sommerville, et al., 2004). The snagging aspect
is regularly disregarded and the works involved under estimated. It is clear
that the construction industry need methods that have the ability to simplify
