Wide range of MK System capabilities at Interlomas Viaduct, Mexico

Forming part of Mexico City’s transportation infrastructure development plan, this viaduct reaches 227 m in length to connect the residential and commercial area Interlomas with the Naucalpan-Toluca Motorway.

One of the defining requirements for this project was the demanding timeline. ULMA designed a solution fully tailored to meet the pace and needs of the client: gantry falsework for two 59 m outer spans, and a CVS Form Carrier for the central span of 108 m.

ULMA’s engineering team combined robust OC Shoring with the Heavy Duty MK Shoring system to shore the deck at heights greater than 15 m, thus adapting to the steep terrain. An MK Truss, placed between a pier and the MK Shoring assembly, covered a gap more than 20 m in length.

For the central span, the flexibility of the CVS Carriage made it possible to adapt to the irregular deck thickness – which ranges from 3.4 m to 6.5 m at the pier segment – even while ensuring rapid completion of the 4 m bridge segments.

The two hollow piers with rectangular cross-section measure 42 m in height, and were built in 5 m segments with ENKOFORM V-100 formwork set on CR-250 roll-back climbing brackets. The advance carriages started work on both of the pier segments at the two extremes of the central span, advancing toward each other until meeting at the end segment.

The MK System once again demonstrated the wide range of its capabilities, serving at once as an advance carriage, shoring system, heavy-duty truss, and a formwork solution. A single system that serves for an entire project.
