At one of the largest transport hubs in eastern Africa – the Jomo Kenyatta International Airport in Nairobi – a fire in the main airport terminal destroyed the international arrivals area in August 2013. As the fire also destroyed facilities for national air traffic, it was essential that work on the construction of temporary departure and arrival terminals started without delay for both national and international flights, to ensure that disruption to passengers was kept to a minimum.
As the design and new construction of a typical airport building made from concrete and steel was out of the question, due to time restrictions, it was decided to create additional departure and arrival terminals in semi-permanent, temporary buildings.
The structure needed to be able to handle a capacity of 2 million travellers per year, in accordance with the IATA Code C Service Level, and also needed to be available on site for a period of ten years. It was also decided that the structure must comply with strict Kenyan building regulations, being able to withstand wind speeds of up to 150 km/h. They also wanted a provider who could handle the entire project: offering and delivering a ready to use solution.
This complex and unique project presented an interesting challenge to HTS.
Although five leading companies took part in the tendering process, HTS Clear Span Structure Systems received the contract and started work immediately.
Starting with ground preparations, HTS Clear Span Structure Systems worked together with companies from the region to establish a stable concrete foundation with fully integrated waste and fresh water pipes, supply lines for fire fighting systems, fresh water storage and power lines.
The main frame structure was designed and produced in the German factory during the 8 week preparation stage and was then shipped to Nairobi upon completion. The construction of the 40 m wide and 250 m long insulated structure took only slightly longer than 8 weeks.
The structure was equipped with more than 10,000 m² of thermally insulated roof canopies made from UV-resistant PVC, insulated composite wall panels, noise and heat insulating windows and doors, roller shutters and insulated panels. In addition, the rear part of the structure was also installed with several external roofing areas, to offer protection against rain and heat for baggage handling.
The subsequent internal organisation of the terminal building then took an additional 10 weeks: involving electronics, 28 toilet units, 54 internal rooms, fire protection, video surveillance, climate systems, 28 check-in desks, 6 passport controls, 6 security stations, separate baggage handling systems for departures and arrivals in line with the latest security regulations for baggage screening, interior and exterior lighting, IT, fibreglass wiring, phone and loudspeaker systems, equipment and outdoor facilities. Personnel were also educated on and trained in using the new equipment, as well as being trained on proper maintenance of the equipment.
A fully-functional airport terminal building was designed and manufactured in Germany and then transported to Nairobi in Kenya, where it was then constructed in June 2015: on time and on budget, within 12 months of the confirmed order date.
The terminal building was up and running and offering additional capacity for national and international air traffic both to and from Nairobi.
With the temporary airport terminal in place, the customer can now focus on the complex development work for the newly planned permanent installation. HTS Clear Span Structure Systems is proud to have been part of such an extensive and prestigious project.
