NEOM ,094-i. Impact of each OBSTACLE POINT. Obstacle Description Impact on Lot 10.7 Notes 3-Delay of Gabion Rock delivery to site Many schedules promised, still no delivery to site started from AL Harbi Impact to progress based on base line time schedule Impact to project cash flow Risk of flood to be facing the unprotected dikes Still no delivery 4-Delay of MST rev.02 Approval for 86 tress translocation Trees No. 86 that clashes to existing expanded site stockpile area which need urgent translocation due to expansion of stockpiles due to not starting haulage of excavated materials - Difficulty of excavated material stockpiling process which delays the whole excavation process Still UR 5-Repeated changes of excavation typical section width ,depth and bottom shape Project typical excavation section changed four times which cause many repeated changes of plans, activities and methodology for excavation Impact to progress based on base line time schedule Impact to project cash flow - Unknown final bottom level causes slope start point conflict Still no final section that any one officially confirms it is last and final section.

NEOM ,094-i. Impact of each OBSTACLE POINT. Obstacle Description Impact on Lot 10.7 Notes 6-Existence of ground water table without officially confirmed final bottom of excavation level Ground water table has been hilted at CH+86.270 and CH+86.800 and expected along the first KM above TOR+1.5 m while the required final design bottom level still not confirmed Dewatering system design is not possible without confirmation of final required bottom excavation level Raised RFI for this issue Still no confirmation of final bottom excavation level to commence dewatering system design 7- Many Raised RFIs not answered Find next page some of the most important still outstanding RFIs Mis planning Mis design Delay of site activities Still outstanding RFIs.
