In February 2001, Lima Airport Partners (LAP) started working at the International Jorge Chávez Airport to turn it into one of the leading private airports in the area. In October 2002, LAP and Overseas Bechtel Inc – Peru (OBI) carried out the whole project of redesigning and extending the airport for the 2003-2005 period. The most important parts of the project were: - Final design and construction of the shopping area ‘Perú Plaza’ and the building for boarding and arrivals (Passenger Terminal). - Modifications on the platforms and relocation of the airport operations This project included modifying, extending and demolishing structures that already existed, as well as adapting and building temporary facilities for the airport to continue operating normally. The safety and environmental systems of the project obtained a very high result in one of the audits that was carried out on the project. The total amount invested in the project by Betchel-Cosapi was $104 million for the 2003-2005 period.
For the concrete structures in the extension of the new terminal building, we used several formworks form the ULMA Construcción range.
To place concrete slabs we used ENKOFLEX, a horizontal wooden beam frame with three-layer boards. We used BRIO as shoring with this system.
For the circular columns we used CLR formworks. For the concrete works we used BRIO towers so the operators could work on a safe platform.
The COMAIN Hand-held Formwork was used to install the wiring in different places, and to build bases and dwarf walls. It was also used to install the beam formwork.
The wall formwork system was built with the vertical ORMA Formwork, mainly using 2.70 x 2.40 m panels. The rectangular columns were built with the great range of panels of this system.
Several BRIO ladders were assembled in different parts of the site to allow access to the structure levels that were built gradually.
For the concrete block enclosures the Multidirectional BRIO Scaffolding was installed with platforms at different levels.
Until then, in the part of the terminal that was being redesigned and adapted we had to use systems that would not interfere with the normal operation of the terminal, because the activity in this part was not interrupted for the project.
To remove 5000 m2 of asbestos from the ceiling of customs and of the main hall of the airport, as well as for the electrical, mechanical and electromechanical installations we needed two types of platforms: one that would isolate the area and another one that would bear greater loads, allowing the affected areas to operate 24/7. The solution that was chosen was the BRIO Multidirectional Scaffolding.
One of the main reasons to use this scaffolding was to be able to work without interrupting the operation and passenger traffic at the airport. The best solution was scaffolding suspended by threaded rods, adjusted with hexagonal nuts, and beams supported all the weight. BRIO platforms covered 6000 m2 and 4000 m2 of the platforms were covered with three-layer boards. The scaffolding had baseboards and railings and needed to bear the weight of materials and cables.
The parts of the BRIO Multidirectional Scaffolding are easy to assemble and disassemble and they adapt perfectly to the building. It had a wide span to allow 5 and 6-ton trucks to get past.
