Extension of the Santiago de Chile Airport


IDOM has developed the Architecture and the MEP of the Auxiliary Buildings for the Extension project of the international AMB Airport in Santiago: Fire Prevention Service (FPS) and Police Buildings, Security Points, Transportation Center and Thermal and Electrical Power Plants.

The project covers an area of 350,000 m2

The Carabineros building has a clear difference on the ground floor between the access area and basement, the office area and the dining area. On the upper floor there is a clear symmetry in the male and female dormitory area. The building is perceived as a clear volume of concrete with a ground floor protected by lattices. On the facade two large windows with flared shape are distinguished that lighten the overall volumetry.

The FPS building includes a veterinary clinic area on the ground floor, with a clearly separated kennel area. On the first floor is the headquarters area, living areas, instruction rooms, a kitchen and dining rooms. On the second floor, the bedroom areas are arranged symmetrically. The second floor has terraces that formally distinguish a void in the general volume of the building, while the ground floor is slightly set back from the general overall volume. The concrete facades enhance the character of the elevated body of the complex.

In addition to these buildings, IDOM has carried out the architectural projects of the rest of the auxiliary buildings included in the airport expansion works.

The project, which is being developed using BIM (Building Information Modeling) technology, covers an area of approximately 350,000 m2.

A new power plant with an Installed Power of 15.6 MW has been designed using 3 chillers of 5.2 MW each, connected to 3 cooling towers of 6.1 MW each and a Heat Installed Power of 9.5 MW using four gas boilers of 2.37 MW each.

The current electrical substation has been expanded with the addition of two 11.25 MVA company feeders. The Installed Power in transformers is 30 MVA. An emergency supply is available through 12 MVA generators and a 120 kWp photovoltaic installation.

Both the new terminal and the new parking buildings have an automatic extinguishing system using water sprinklers, over 18,000 units and 48 hydrants in the exterior.

For the treatment of sewage, a new treatment plant has been designed with an average flow of 65 l/s and a maximum flow of 165 l/s.

In the design of fire protection, the most appropriate protection measures have been defined, seeking integral solutions, with the aim of effectively preserving the integrity of people and property from the dangers and effects of fire.

This includes fire extinguishers, fire cabinet network, water sprinkler network and inert gas systems for server rooms.

The entire water network is fed from the reserve ponds (2×300 m3) and the fire pressure group equipped with an electric pump, diesel pump (300 m3/h, 120 mca) and jockey pump (3 m3/h, 124 mca).

Likewise, a network of fire cabinets and hydrant system has been designed for the entire area of the project.

As a critical infrastructure, the airport has important security requirements, for which IDOM designed CCTV, access control and public address systems. In addition, the entire airport was equipped with an IP network, in order to provide ever more necessary connectivity to accommodate the most modern technologies. This network is connected to a Data Processing Center (CPD), also developed by IDOM, and a control center was designed to control security throughout the airport, also providing it with all available technologies for early detection and the control that such an infrastructure requires.
