Highway Design Engineer Parsons International Company Limited
October 2011 to Date (PICL Muscat, Oman)
Worked on two major projects from start to finish out of which one is:
i) Dualization of Adam - Thumrait Road Oman (US$2bn) is a new two-lane road to be constructed adjacent to existing road to form two-lane dual carriageway. Length of project road is 720 km starting from Adam and ending at Thumrait. It includes the design of 44 interchanges, 26 Camel Crossings, 55 Lay-bys, 8 Weigh Stations, 42 big water channel crossings and 12 Rest Areas.
The second project is:
ii) Upgrading of Junctions on Existing Batinah Highway Oman (US $1.6bn) is a four lane dual carriageway comprised of 24 interchanges, including single point urban interchange (SPUI), compressed diamond, elevated roundabout, split diamonds and vehicular underpasses.
• Alignment Study, preliminary and detailed design of horizontal and vertical alignment of main road, interchanges (ramps, bridges and roundabouts), junctions, service roads, cross-section, super elevation, pavement grading plans and pavement classification plans. Prepared and checked issued for construction drawings (IFC) according to the Parsons Quality Policy.
• Designed dumb-bell, split diamond and vehicular underpasses to AASHTO and Highway Design Standards (HDS) of Oman 2010.
• Developed TIN and contours from survey data using IN-ROADS software and designed vertical profile of proposed main road, interchange ramps and cross-roads, camel crossings and water channel crossings.
• Designed super-elevation for main carriageway, interchanges and service roads.
• Checked vertical clearance of interchange bridges from main carriageway and provided finished road levels to structural team for design of bridges.
• Developed proposed main road and interchange cross-section templates in IN-ROADS software and computed earthwork quantities.
• Prepared standard drawings for rest areas, lay-bys, emergency median opening, camel crossings and weigh stations along main road.
• Designed pedestrian crossings where main road traverses through urban areas.
• Provided guard rail and barriers at hazardous locations along the project road.
• Followed Parsons Quality procedures and checked drawings before submission.
• Associated with pavement design.
• Attended meetings with client, local authorities and other stakeholders. Collected and implemented their requirements and got design approvals at alignment study, preliminary and detailed design stages from client.
• Took the responsibility to finish the time critical projects and assigned tasks to junior engineers in order to distribute the work load. For better quality and production motivated and assisted junior engineers to improve geometric design skills and learn InRoads software.
• Liaised with utilities, structural, drainage and CAD departments to finalize the design.
• Accomplished the project with minimum input from design manager.
