PROJECTS AND CONTRACTS

AIRPORT UPGRADE

Kilimanjaro

Construction supervision of the €37-million (R450-million) upgrade to Tanzania’s Kilimanjaro International Airport is to be undertaken by local consultants Royal HaskoningDHV and Tanzanian subconsultant, Howard Humphreys. Work is due to start in July this year and be completed by early 2017. The project is funded in part by the Dutch Grant Facility for Infrastructure Development (ORIO) and partly by a commercial loan to the Tanzania Ministry of Finance.

The Terminal building will be reconfigured and rehabilitated, including: • The creation of a central commercial lounge and separate waiting areas for domestic and international passengers • Improved security and passport control processes to modern international standards • Construction of a new roof terrace to increase the capacity of the lounge area. “The existing terminal building was built in 1971 and is generally in very good condition. By rehabilitating the building, rearranging the spaces and creating a new covered roof terrace we are able to extend the lifespan of the building and revitalise it. This will minimise the need for new resources and materials in construction. The end result will relieve congestion, provide space for future growth, create new opportunities for commercial activities and greatly enhance the passenger experience at the airport,” expounded Langeslag. “A challenge to the professional team is that the airport has to remain opera- tional throughout the entire duration of the works. This impacts the scheduling of the works, and requires temporary provisions and pro-active management of stakeholder expectations. The goals are to maintain safe airport operations at all time, and to minimise the adverse impact on passen- gers, airlines and other stakeholders at the airport,” he said. Gateway to Africa's wildlife heritage Kilimanjaro is one of East Africa’s most popular tourist destinations, with nearby attractions such as the Serengeti National Park, Ngorongoro Crater, Lake Manyara and of course Mount Kilimanjaro. Kilimanjaro International Airport (KIA) brands itself as the Gateway to Africa's Wildlife Heritage and provides a key entry point to the region known as the Northern Tourism Circuit in Tanzania.

Company spokesperson and project manager Marcel Langeslag explained that the construction contract was the culmination of

the donor organisations to get the project off the ground. We have been able to assist the airport with a wide range of services, including master planning, civil engi- neering and terminal building architecture,” explained Langeslag. The scope of Royal HaskoningDHV’s involvement includes the design review of the detailed designs that will be prepared by the Design & Build contractor, contract administration of the Design & Build contract as the Employer’s Representative (the engineer) and supervision of all construction works on site. Scope of work Kilimanjaro International Airport saw more than 800 000 passengers and more than 20 000 air traffic movements in 2013. Overlapping peak hours for domestic and international flights caused congestion in the Terminal Building and further traffic growth will put pressure on the 3 600 m long runway. Upgrades and expansions are required to accommodate the expected future growth of air traffic at the popular tourist destination. On the airside this project includes: • Extension of parallel taxiway to enhance runway capacity • Expansion of apron to create more aircraft parking stands • Rehabilitation of all airside pavements

several years of preparatory work by three Royal HaskoningDHV Group companies – its South African operation, NACO – Netherlands Airport Consultants and InterVISTAS. “Strong traffic growth and the mix of domestic and international flights at the airport have resulted in capacity constraints and this rehabilitation and expansion project will relieve congestion and provide capacity for future growth. It will also ensure the airport is given a make-over that will enhance the passenger experience,” he said. “In 2012 we were appointed for the update of the master plan, which was completed in early 2013. Subsequently, we were appointed for the concept and preliminary design of the rehabilitation works and the preparation of Design & Build tender documents. For the past three years colleagues from our sister company InterV- ISTAS have supported Kilimanjaro Airports Development Company (KADCO) in Air Services Development, increasing air traffic at the airport, and winning threeRoutes Africa Awards in the process (2013, 2014 and 2015). “Royal HaskoningDHV and NACO have been involved with this project from its inception, working closely with the client and
