PROJECTS GRAN MANGLAR VIADUCT CARTAGENA DE INDIAS, COLOMBIA BACK TO ALL PROJECTS A VIADUCT BUILT THROUGH A NATURE RESERVE WITH THE INNOVATIVE TOP-DOWN METHOD The Gran Manglar Viaduct is part of the project for the construction of the Cartagena de Indias e Barranquilla highway. The viaduct is 3.7 km long and crosses the Cienaga de Tesca lagoon. For the construction of the viaduct a top-down construction method has been chosen. All structural elements, including piles, pile-caps and beams, are made of precast concrete and are erected using a special erection equipment designed for this type of construction which does not require access from the ground. COLOMBIA'S LONGEST BRIDGE, WHICH WILL PASS OVER THE LA VIRGEN SWAMP AT CARTAGENA, WILL BE READY IN JUNE 2018, FOUR MONTHS AHEAD OF THE ORIGINAL SCHEDULE PRESIDENT JUAN MANUEL SANTOS EXECUTION PROJECT Gran Manglar Viaduct COUNTRY Colombia YEAR 2018 THE SOLUTIONS MINIMAL DISRUPTION The top-down construction method avoids the need for dredging, concrete slabs and the construction of access roads, which otherwise would have damaged the natural reserve for years. The solution consists of a launching girder which is able to drive piles in the marshland and to launch pile caps and girders. REQUEST INFORMATION PRECASTING PROCESSES TO MANTAIN SCHEDULED DELIVERY TIMES The viaduct consists of 129, 37m-long spans and it is entirely made up of prefabricated, prestressed concrete elements, excluding the completion elements and the cast-in-situ slabs. Prefabrication of the elements takes place in a precast yard adjacent to the abutment 130. The implant consists of three production lines: pile caps, piles and girders. REQUEST INFORMATION PROJECT PHASES TENDER STAGE PRECAST YARD VIADUCT ERECTION # An alternative construction method has been implemented starting from the original proposal envisaged by Colombia's National Infrastructure Agency, and resolves all the projects requirements and issues. A similar project has already been developed by Deal on the Washington Bypass, North Carolina.
