Please describe the project specifications

Opened in 1954 and located in Antofagasta, is currently the largest passenger airport in the II Region of Chile. During 2011 multiple options for the roof were developed, in form and color, including single layer proposals with copper color inserts, characteristic mineral of the region, and also transparent stripes. Finally at the end of that year and after studying the proposals AB Architects define it to be total white and with a double layer to control thermal and lighting aspects. With the draft already defined, in 2012 we started to develop the final engineering and other specific details of the membrane cover.
The cover design remained the same structural modulation of the existing building, resting on the beams and columns each 12m. The area to expand maintained the same condition. The deck was organized in thirteen typical modules and a module for each end, north and south, covering 8300m2. Each module is developed between two main beams and these in turn into two parts West and East divided by a central axis. The whole surface was about 18,400sqm.


What was the purpose of this project? What did the client request?

The current building built in 1972, was arranged to be modernized, so in 2011 started the task to develop the project for remodel and expand the airport. The building was re-designed by Amunátegui Barreau Architects, who decided that the best option would be to cover it with a tensile structure, basically because the membrane was appropriate for the weather and lighting conditions in northern Chile and the aesthetics benefits, it was conceived as the unifying element of new and existing works. To achieve this, A-Port currently responsible in Chile for the operation, administration and management of the airport, asked CIDELSA to design and develop the tensile structure solution, this work was conducted in joint work with AB Architects.


What is unique or complex about the project?

It is unique because is the first Airport in South America with a textile roof over the whole building, we use 27,000 sqm of membrane, type II for the outer layer and Type I for the ceiling.
It was quite complex to design over an existing structure, architecture and engineer details were very tough. Also during the construction, because it must be scheduled in two phases to avoid interrupting the normal operation of the airport.


What were the results of the project?

The results were good, we had some normal problems during the construction, but they were solved efficiently and on time, finally the client was happy with our product and management.
