Missing Basic Documents• Approved Traffic Study, Traffic Counts and Approved Conceptual

DrawingsDespite 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 keyelement 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 anymajor modification during the preliminary stage (Basic Design).

•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:

Transition Length for Causeway Extracted from Employer’s Concept Design Drawing RA/140/1001-2

• Weigh Bridge at Shuwaikh Area

• The proposed location of weigh Bridge in Shuwaikhinterchange will result in the constraint of the length ofmerge/diverge Taper which is not in line with thedesign standards.

• It will also have an effect on weaving length betweenWeigh Bridge Taper and approach junction with visitorcenter road.



45 of 125

• Minimum GradientThe Design criteria for the project clearly mentioned thatthe minimum desirable longitudinal gradient forsatisfactory drainage is 0.5%.The drawings submitted show a minimum gradient 0%.

The ramps (or connecting roadways) within a grade-separated interchange shouldnormally have a lower design speed than the mainline

• Interchanges

• Non-reflection of rest areaRest area already built by RA126 project was notconsidered in the Employer’s Concept Design Drawings.

Current design of the Interchange does not comply withKDM requirement and overlapping occurs betweenacceleration lane of vehicles from the ramp of theInterchange and vehicles approaching towards restarea.

• “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.

• Current seabed level is about -4.0mPWD (about 9m of reclamation isrequired to reach the target level +5mPWD for Bay Island North platform)• Improvement of natural compressible(soft clay) foundation soils wasconsidered necessary to meet projectserviceability and stability requirements• Preloading with the use of PVD (only)was proposed by the Contractor(tender design implements stonecolumns at the perimeter bund as well)as the ground improvement technique.

• 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

• 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

• “BASIC DESIGN” REVIEW FINDINGS• Pavement and Material Design

• Pavement cross-sections were submitted for the following locations as per Concept design drawings:

• Shuwaikh Interchange• Subiyah Interchange

• Detailed pavement design calculations for each pavement section are not yet submitted

• Approval of final pavement design for construction shall be concluded upon the receipt of traffic volumes and defining the subgrade strengths at each location

Key areas of focus – April 2014• Inspections of seasonal monitoring:

• Algal beds (to start in April: 25 locations);• and Fish and Shrimp monitoring (25 locations

remaining).

• Establishment monitoring of New Vegetation Habitat –Scheduled end of April and end of May.

• Continue to work with contractors regarding development of key environmental management activities:

• Spill Response – Marine environment;• Pollution prevention - Terrestrial;• Chemical and waste management.
