project performance. These problems include the political situation,
border problems, and financing problems.
The top five severe causes of delay as seen from the combined
view of contractors and consultants are the following:
• Political situation;
• Segmentation of the West Bank and limited movement
between areas;
• Award project to lowest bid price;
• Progress payments delay by owner; and
• Shortage of equipment.
Conversely, the bottom five causes of delay as seen from the
combined view of contractors and consultants are:
• Poor ground condition;
• Insufficient inspectors;
• Inappropriate design;
• Monopoly; and
• Natural disaster.
The value of the Spearman’s rank correlation coefficient of 75%
indicates that there is relative good agreement between contractors
and consultants on the severity rank of the delay causes.
The statistical analyses of the data show the following: (1) No
participant response specifies any cause with no influence on the
delay of road construction projects; (2) there are no causes with a
severity index less than 30%; and (3) the groups, index is between
45 and 61%. These all indicate that the identified causes are highly
relevant to the problem of delay in road construction projects in the
West Bank.
