construction projects from the contractors’ view are

• Materials and equipment (severity index = 60%); and
• Laborers (severity index = 58.59%).

span; it ranges from 49 to 62. The results show that the design
group is the one with the lowest severity index of value
of 49.02%.

the design group is the one with the lowest severity index of value
of 41.33%.
Table 18 shows that the top three groups of delay in road
construction projects from the combined view are
• Materials and equipment (severity index = 60.23%);
• Owner (severity index = 59.8%); and
• Laborers (severity index = 57.69%).
Table 18 also shows that the groups’ severity indices have a
short span; it is ranges from 45.4 to 60.2. The results show that
the design group is the one with the lowest severity index of value
of 45.42%.
