Case Study Bringing structures to life KAIA Infrastructure Client: General Authority of Civil Aviation of KSA Contractor: Saudi Binladin PBAD Location: Jeddah, Kingdom of Saudi Arabia Products: Special Formwork, Rapidshor, Megashor, Maxima As part of a major redevelopment of the KAIA Airport, which is focussed on improving its infrastructure through the construction of new terminals and enhanced transport links, RMD Kwikform engineers have developed a number of formwork and shoring solutions to support the new approach roads. The newly developed airport will be able to cater for 35 million passengers annually, more than doubling its existing capacity. There were three main shoring elements of the project that RMD Kwikform was involved in – the roadside decks, curbside arch and the curbside road decks. Commenting on the project, Gabriel Hackett, Sales Manager for RMD Kwikform Saudi Arabia said: “This large-scale and multi-faceted project presented us with a number of challenges that we had to overcome. Primarily, each of the three sections of the road construction that we were involved in required a unique design solution to ensure it would be completed to budget, and to schedule. “The construction of the roadside deck was challenging, primarily due to its scale, and the volume of equipment that was required. Over 1,000 tons of Rapidshor shoring, supporting 500 tons of specially fabricated steel deck panels, was used to construct the roadside decks. The steel deck panels were placed on top of the Rapidshor, giving the profiled curved decks the high quality finish that was required to ensure this section was in keeping with the aesthetics of the other airport developments. The modular design of Rapidshor meant it could be quickly and safely erected, and dismantled throughout the phased programme. When it came to the deck, we had to specially design the steel deck panels in order to ensure they could be craned off the Rapidshor system after the concrete on the deck had been cured, and moved to the next section of road very quickly. This was an incredibly efficient way of dealing with this section of construction, and really utilised the strengths of the Rapidshor system.” The next section of the elevated approach roads that RMD Kwikform was involved in was the construction of the curbside arches. Rapidshor shoring was used to support the specially fabricated steel forms, which were designed and constructed to form a twin leaning arch, which was to be used to support the road deck via a crosshead beam adjacent to the airport. The customers’ brief was to design a system that would enable them to cast the complete pier, which included two arches and 12 columns, on one single pour. Due to the scale and complex geometry of the pier; 30m long, 15m high and 10m wide, a three dimensional model was created to ensure the accuracy
