The accuracy and reliability of delay analysis performed
by existing techniques are thus highly influenced by the availability
of adequate project information, most of which are program
related. A major source of the information is also generated by
contractors on a periodic basis in the form of statused/updated
and revised programs (Fruchtman 2000; SCL 2002; Arditi and
Pattanakitchamroon 2006). The timely keeping of this information
in an accurate, well-organized manner throughout the life cycle of
the project is a key task in preparing, analyzing, and resolving delay
claims (Pinnell 1992; Pickavance 2005). Therefore, many of the
issues affecting the proper analysis of delay claims and their settlement
relate to how construction programs are developed and
maintained in the course of construction.
