3.1 What is snagging?Snagging is a procedure used withinthe construction industry to check newly constructed buildings for minordefects and faults that have to be rectified by the developer or contractor. Snagging is part of the procurement proceedingsin the construction industry and can influence the productivity and performanceof construction companies. Numerous factors that influence quality can beconnected to the design of the project and poor workmanship. Snagging includesthe correcting of errors and faults which includes ineffective work. Therefore, the costs that apply to snagging shouldbe measurable for construction companies and contractors ( Sommerville, et al., 2004).
2.3.2 The Snagging ProcessSommerville & McCosh (2006) suggested that snagging methods are generallyfocussed on checking properties for poor workmanship but, by its very natureand complexity, the house building procedure frequently leads to minor defectsbeing identified in the finished product. Diagram1 illustrates that the purchaser has very little input in the interpretationof the functional requirements of the property or its quality standards.
Thedeveloper sets and manages the quality standards and, as diagram1 illustrates, there are only two opportunities for rectifying defects prior tothe handover of the property (Sommerville & McCosh, 2006). Numerouscompanies in the construction industry use a paper-based snagging procedure torecord and manage the snagging process. This paper-based method results in along and time consuming process where the recorded information has to be typedup, scanned and copied in order to send information to the contractors who inturn are responsible for correcting the defects ( Sommerville, et al., 2004). The snagging aspectis regularly disregarded and the works involved under estimated. It is clearthat the construction industry need methods that have the ability to simplifydata
