Hill provided consulting engineering services for the expansion and modernization of Muscat International and Salalah Airports. The expansion of Muscat International Airport, the largest airport in Oman, included a new terminal capable of accommodating 12 million passengers annually. The expansion of Salalah Airport, the second largest airport in Oman, involved upgrading it from primarily a domestic airport to one suitable for international travelers and building a new terminal to increase the airport’s capacity. 

Hill was brought on to the project to replace the former consulting engineer and provided such services as construction supervision, stakeholder and interface management, technical reviews and management, risk management, permitting and approvals support and assistance, contract management and administration, cost management and control, claims management, scheduling, quality management and control, HSE management and control, meetings and reporting, document control, and training and knowledge transfer. To perform many of these functions, the Hill team deployed the data management system Aconex.

The expansion of Muscat International Airport included a 97 meter air traffic control tower, a new 580,000 SM passenger terminal building, 96 check-in counters, a baggage processing facility that can handle 5,500 bags per hour, 29 passenger boarding bridges, 30 aircraft remote stands, and 2 parallel runways. Other ancillary airport buildings, including a 90-room airside hotel, have a total area of more than 30,000 SM.

The expansion of Salalah Airport included building a new runway long enough to handle the A380 Airbus and a new terminal that increases the airport’s capacity to one million passengers annually. The new Salalah Airport has a 57 meter air traffic control tower, a passenger terminal with 65,000 SM of floor area, 24 check-in counters, 8 passenger boarding bridges, 8 aircraft remote stands, and 4,000 LM of runway equipped with the latest navigational instruments and automatic landing systems.

These projects used both design-bid-build and design-build delivery methods and were divided into multiple contract packages. 

Highlights of the Hill team’s work for these projects included overall integration and coordination of contract requirements, interfacing with the client and the relevant agencies and stakeholders, establishing and implementing project-specific procedures to provide a structured and organized project environment, refining the existing project documentation process to maintain a system that could be easily understood and implemented by all project parties, developing an effective Project Quality Plan and monitoring the strict implementation of quality controls to safeguard the client’s objectives and requirements, and developing an HSE Plan and monitoring the strict implementation of safety controls to protect the participants’ safety.

The project won the 2019 MEED Mega Project of the Year Award, MEED Middle East Business Intelligence.
