New terminal for Lima Airport

The Aeropuerto Internacional Jorge Chávez in Lima, Peru, is getting a new terminal – and BEMO is playing a central role in this. In order to equip the country’s most important airport for the increasing number of passengers, 1.5 billion dollars will be invested as part of a comprehensive expansion program. In addition to a second runway, which was already opened in April 2023, a state-of-the-art terminal with innovative roof and façade solutions from BEMO will be built by 2025.

The new terminal is located on the northern edge of the city of Callao, directly on the Pacific Ocean and about ten kilometers from Lima’s city center. The developer and operator, Lima Airport Partners (LAP), is a joint venture of international investors, including Fraport AG from Frankfurt. The aim of the project is to significantly increase the capacity of the airport while meeting the highest architectural and technical standards.

Behind the major project is the renowned general contractor Consorcio Inti Punku, which led the implementation on site. Our partner FORMAMOS ACERO S.A.C. from Lima-Peru was responsible for the entire material procurement and logistics and commissioned the company AguilarDeck, also from Lima-Peru, for the façade and roof installation.

A project of this magnitude entails high technical requirements. A sound insulation of 45 dB was required for the terminal in order to effectively shield the noise of the aircraft. At the same time, excellent thermal insulation with a U-value of 0.16 W/(m²K) had to be achieved in order to air condition the building in an energy-efficient manner. Special attention was paid to ensuring that no fastenings of the roof structure are visible from the inside, so as not to disturb the modern, elegant design.

In addition, a fully perforated trapezoidal sheet metal was used in the roof area to achieve maximum sound absorption inside the building. These technical requirements demanded innovative solutions and precise execution – and this is exactly where BEMO was able to contribute its expertise.

A complex multi-layer construction was developed for the roof. A fully perforated steel trapezoidal profile was used as the supporting shell, which was laid out with acoustic fleece and acoustic insulation in order to meet the strict requirements for reducing the sound reflection on the room side.

In order to ensure the load-bearing capacity of the further roof structure, statically load-bearing top-hat profiles were inserted into every second trapezoidal valley. Two layers of cementboards and a Tecsound membrane were laid over these top-hat profiles before the BEMO thermal halter type 205/80 made of GRP were attached through these layers into the top-hat profiles – invisible from the inside. This preserves the elegant ceiling look in the terminal. Two layers of mineral wool of 80 mm each were used for thermal insulation, which provide excellent insulation. The water-bearing level consists of BEMO N65/500 standing seam profiles made of aluminium, mill finish and matte, which are not only functional, but also visually impressive.

The façade of the new terminal was also implemented with innovative solutions. Vertically mounted steel sandwich panels with an inner core of 125 kg/m³ ensure high sound insulation values and a smooth interior appearance. An additional Tecsound membrane further strengthens the sound insulation and two layers of mineral wool à 90 mm provide the required thermal insulation.

Horizontal top-hat profiles serve as the substructure for the BEMO Thermo Halter Type 225/80 made of GRP, which were also mounted invisibly. This preserves the modern design of the interiors. The outer shell of the façade consists of BEMO N65/500 standing seam profiles, which are characterised by their durability and elegant appearance.

For the roof, around 23,000 m² of parallel and 3,000 m² of tapered standing seam profiles were used. The façade comprises about 36,180 m² of parallel standing seam profiles. The material is made of aluminium with a mill finish surface and a matt anodizing of 5 μm, which ensures a high-quality, weather-resistant and aesthetic appearance.

A special highlight of the project was the on-site production of the parallel and tapered standing seam profiles. This not only reduced transport costs, but also significantly shortened the construction time. Despite the large distance and time difference between Peru and Germany, BEMO ensured round-the-clock support and thus guaranteed a smooth implementation.

The innovative construction method also contributes to sustainability: The thermal bridge-free BEMO thermal brackets used ensure significant energy savings in the air conditioning of the building. This not only reduces energy consumption, but also contributes to environmental protection.

The new terminal at Aeropuerto Internacional Jorge Chávez sets new standards not only architecturally, but also technically and ecologically. It impressively shows how innovative products and close cooperation between all those involved create a future-oriented building.

BEMO makes a significant contribution to this with its intelligent roof and façade solutions as well as project-related advice and support, thus underlining its position as a leading supplier of high-quality building components. The project is an impressive example of how modern architecture, functionality and sustainability can be successfully combined.
