Gorge Made Travel
Difficult in Past

EFCO has participated in many major road projects in the Macro Southern Region of Peru and this project is no exception.

Bridge Huarangal Consortium was awarded the first stage of the construction of the Huarangal Bridge, which consists of an arc spanning 211′ (64.31 m) long and 67′-4″ (20.50 m) high from the natural terrain to the crown. An embankment was built to improve the terrain, which reduced the height toward the crown, creating 51′-7″ (15.70 m) in shoring height. Seen from above, the widths of the ends of the bridge are 67′-8″ (20.60 m) and 83′ (25.00 m), and the center of the bridge is 25′-8″ (7.80 m) wide.

The New Huarangal Bridge

The Torrentera Huarangal Gorge serves as natural drainage for rain and severe storm events which can make travel difficult for the community of 7,838. The new Huarangal Bridge will provide pedestrians and vehicle traffic with suitable conditions all year long.

Solution

Once the terrain was leveled into an embankment, the first step was to support the endpoints at the footings of the arc. This was quickly resolved by using EFCO SUPER STUDS®, which are ideal at withstanding diagonal loads because of their high compression capacity.

Next, shoring was needed to support the entire span of the bridge. The main requirements for this were: a light and practical system to minimize the volume of equipment to be moved because of the terrain and equipment that required the least amount of labor. Thus, EFCO’s E-Z DECK® system was chosen. Because its high-load capacity post enables greater spacing and higher productivity, it was the best solution.

The technical, logistical, training and jobsite support provided by EFCO allowed for us to successfully complete the project. We will surely work together again in the future.
