Missing Basic Documents •

Approved Traffic Study, Traffic Counts and Approved Conceptual Drawings

Despite the effort done thankfully by MPW, We have not received the approved traffic study (by KM and MOI) for the project which should include the Traffic counts (approved by MOI), also we didn’t receive a copy from the approved design presented to KM and MOI. The following is to be noted: • The traffic study for the project is one of the most important fundamental elements for the design of the project, starting from the number of lanes, determine the level of service, type and configuration of interchanges / intersections. • The traffic count data that are based on the study of traffic is also a major key element to calculate the pavement structure for the different type of roads. • The approval of design at concept stage by either KM and MOI will avoid any major modification during the preliminary stage (Basic Design).

Design Issues (Under Discussion) •Transition length for Causeway The KHDM and AASHTO are very clear and strict about the maximum allowable length for the transition curve which shouldn’t exceed √24R in addition to what stated into KHDM, and as per AASHTO, safety problems have been found to occur on spiral curves that are long. Such cases were investigated as per below table:

Curve No.

Design Issues (Under Discussion) • Weigh Bridge at Shuwaikh Area • The proposed location of weigh Bridge in Shuwaikh interchange will result in the constraint of the length of merge/diverge Taper which is not in line with the design standards. • It will also have an effect on weaving length between Weigh Bridge Taper and approach junction with visitor center road.

43 of 125 MINISTRY OF PUBLIC WORKS Roads administration

Design Issues (Under Discussion) • Minimum Gradient The Design criteria for the project clearly mentioned that the minimum desirable longitudinal gradient for satisfactory drainage is 0.5%. The drawings submitted show a minimum gradient 0%.

45 of 125 MINISTRY OF PUBLIC WORKS Roads administration

Design Issues (Under Discussion) • Interchanges The ramps (or connecting roadways) within a grade-separated interchange should normally have a lower design speed than the mainline

Design Issues (Under Discussion) • Non-reflection of rest area Rest area already built by RA126 project was not considered in the Employer’s Concept Design Drawings. Current design of the Interchange does not comply with KDM requirement and overlapping occurs between acceleration lane of vehicles from the ramp of the Interchange and vehicles approaching towards rest area.

Geotechnical and Marine (11/23) • “BASIC DESIGN” REVIEW FINDINGS • Ground Improvement and Embankment Stability • Subiyah Embankment • • •

Current ground surface elevation is +3.0m PWD (about 2m of reclamation), deep compaction is not anticipated. Improvement of natural compressible (soft clay) foundation soils was considered necessary to meet project serviceability (settlement) requirements. Preloading with the use of Prefabricated Vertical Drains (PVD) was selected as the ground improvement technique.

97 of 125 MINISTRY OF PUBLIC WORKS Roads administration

Geotechnical and Marine (12/23) • “BASIC DESIGN” REVIEW FINDINGS • Ground Improvement and Embankment Stability • Bay Island North • Current seabed level is about -4.0m PWD (about 9m of reclamation is required to reach the target level +5m PWD for Bay Island North platform) • Improvement of natural compressible (soft clay) foundation soils was considered necessary to meet project serviceability and stability requirements • Preloading with the use of PVD (only) was proposed by the Contractor (tender design implements stone columns at the perimeter bund as well) as the ground improvement technique.

98 of 125 MINISTRY OF PUBLIC WORKS Roads administration

Geotechnical and Marine (13/23) • “BASIC DESIGN” REVIEW FINDINGS • Ground Improvement and Embankment Stability • Bay Island South • Current seabed level is about -1.0~-2.0m PWD (about 6~7m of reclamation is required to reach the target level +5m PWD for Bay Island South platform) • Soft soils require ground improvement to meet project serviceability and stability requirements

99 of 125 MINISTRY OF PUBLIC WORKS Roads administration

Geotechnical and Marine (14/23) • “BASIC DESIGN” REVIEW FINDINGS • Ground Improvement and Embankment Stability • Shuwaikh Embankment • Current ground level is about +2.0m PWD (about 3m of reclamation is required to reach the target level +5m PWD for Shuwaikh embankment platform) • Reclamation area is divided into two parts according to soil type: Stage (I) no need for ground improvements. Stage (II) on soft/ loose soils that require ground treatment to meet project serviceability and stability requirements
