In 1983, a highly successful video game called Bugaboo, also known in its various versions as The Flea, known as La Pulga in Spain, was published in the UK and later in the USA. It soon reached number one in the specialised games press. Created by two programmers from Extremadura, it is currently considered the first major milestone in the development of entertainment software in Spain, which is now one of the top 10 biggest players in the sector in the world and the fifth largest in Europe in terms of turnover.

La Pulga, which today gives its name to the Spanish national industry awards, was followed during the 1980s and early 1990s by other well-received productions such as Sir Fred, Livingstone Supongo (both in 1986), La Abadía del Crimen (1987, inspired by the film The Name of the Rose), Commandos, PC Fútbol and many more. All of them gave rise to what is known today as the ‘golden age’ of Spanish gaming, which ended in the early 1990s with the arrival of 16-bit technology.

A growing area of activity is that of serious games, which are being developed by around a quarter of Spanish companies in the sector. These are not intended for entertainment, but rather are designed for educational or training purposes

After a hiatus of a few years, with the turn of the century and the digital revolution, a resurgence began within the sector. In 2010, Castlevania: Lords of Shadow, developed by the Madrid-based studio MercurySteam, was released. The Japanese firm Konami selected them from a number of other American and Japanese proposals to redesign and revamp their product. The result was a mega-production with a budget of 20 million euros, which led to two sequels and became a worldwide critical and commercial success, marking a milestone for the sector in Spain. This is a sector that has experienced sustained growth over the last ten years, both in terms of turnover and business networks, although there is still a great deal of room for further expansion.

According to data from the Spanish video game development association DEV, in 2019, entertainment software production companies –some 400 in total, most of them small and concentrated mainly in Catalonia and Madrid, and to a lesser extent in Valencia and Andalusia– had a turnover of 920 million euros, 13% more than the previous year, 66% of which came from foreign sales. The fact that the main distribution channel is via global platforms on the Internet, mainly Steam, where 83% of Spanish studios make their sales, facilitates the process. According to DEV, physical sales account for only 4% of the total. North America (28%) and Europe (23%) are the main buyers of Spanish video games.

DEV forecasts annual turnover growth of 17% to EUR 1.7 billion by 2023. In terms of employment, the current workforce of just over 7,100 will rise to 8,500 direct jobs.

Indie games

In contrast to global and large-scale video games, the Spanish industry is characterised by the quality of its independent productions, which enjoy great international acclaim due to the originality of their game dynamics and aesthetics. Among the most recent, some of the most successful are Temtem known as the Spanish Pokémon, by Madrid-based studio Crema Games, which sold half a million units on Steam in its first month; or Blasphemous (2019), by The Game Kitchen from Seville, which mixes the folklore of southern Spain with action adventures and combat to the rhythm of guitar and saeta (a popular song typical of Easter), which has already reached one million players on Steam.

Among the best-selling, most-played and award-winning games of the last few years are They are billions, set in a zombie apocalypse designed by Madrid studio Numantian Games, which reached 15th place worldwide in January 2018 on Twitch; Gris, by Barcelona-based Nomada Studios, an intimate story with watercolour aesthetics, which received numerous awards and achieved an average rating of outstanding on the Steam platform; and The red strings club (2018), cyberpunk adventure game by Valencian studio Deconstructeam.

Esports: Beyond screens

League of Legends Smifinal, Vistalegre 2019. / PHOTO_RIOT GAMES

The video game sector’s growth is not only limited to software development, but also encompasses other activities with a high economic impact, such as esports: these are official and professional competitions for various battle and strategy video games, such as League of Legends (LoL), DOTA 2 (short for Defence of the Ancients 2), Fortnite, or Cs:Go (Counter-Strike: Global Offensive). All of them draw audiences numbering in the millions, not only online via streaming (live) on platforms such as Amazon-owned Twitch, but also, until the pandemic hit, face-to-face. That is to say, with audiences flocking to large venues to watch their favourite teams and players perform live. Spain has hosted some of these competitions, such as the 2018 final and the quarter and semi-finals of the League of Legends World Championship, held in November 2019 at the Palacio de Vistalegre in Madrid, which was attended by 8,000 live spectators, and another 1.7 million online during the two weeks of matches.

Esports in Spain generated 35 million euros in 2019, 22.5 million in advertising, which together with sponsorships are the main sources of revenue, according to the Spanish Video Game Association (AEVI). The sector employs 600 people, of which 250 are professional players, and Spain represents approximately 4% of the world’s esports economy, has 2.9 million fans –of which 55% are over 25 years old– and ranks 12th in the world in terms of esports audience share, which is mostly online, as well as having the highest percentage of female fans in Europe at 36%.

The opening of the Madrid–Seville AVE was, certainly, a technological revolution for the world of Spanish railways, a leap forward that put us at the international cutting edge of the technology and construction of track and rolling stock. In a short time, high speed revitalised the railway and changed the modes of transport competing successfully with road and air travel. Through the trust of the Ministry, Renfe, and later Adif, Ineco began to participate in the development of high speed, working alongside many other Spanish engineering and construction firms.

In the start-up of the high-speed line, it was necessary to draw on practically all disciplines of civil engineering and architecture: alignment, geology and geotechnical engineering, structural calculation and design, underground works, hydrology and drainage, environmental recovery, railway infrastructure and superstructure, station design and remodelling, demand and traffic studies, the inspection of bridges, waterways and viaducts, load testing, track inspection and instrumentation, energy and substations, signalling, control centres, operation, etc.

In the start-up of the high-speed line, it was necessary to draw on practically all disciplines of civil engineering and architecture

That is why when Spain’s first high-speed line (and one of the first in the world) was inaugurated 25 years ago, the 250 km/h journey between Madrid and Seville (471 kilometres in under three hours) was for many people a triumph, a celebration almost as important as Expo’92, the major event with which the inauguration was timed to coincide.

Remembering these dates, we also recall those young Ineco engineers and technicians who, taking Renfe’s lead, had the opportunity to participate in this great project. Thanks to these humble beginnings and the expertise, rigour and talent of our professionals, companies in the Spanish rail sector today are more competitive and enjoy a well-deserved international recognition. An example of this is our participation in high-speed projects in Saudi Arabia, the United Kingdom, Turkey and India.

The UN’s Habitat III conference in Quito and the future role of transport in cities; the study of Europe’s main transport routes; modernisation works for a railway line in Turkey and the latest innovations in improving European air traffic; these are also important themes to analyse, and we hope that our readers find them enjoyable and interesting.

The environment, which takes centre stage on this autumn’s cover, increasingly influences our projects and activities in Spain and around the world. With the support of Ineco, Ecuador’s capital Quito has launched initiatives to reduce waste and foster a circular economy of resources; this will without a doubt translate into improved welfare and quality of life for the city’s inhabitants.

Public policy is key in the move towards more sustainable cities. We are honoured with the opinion of María Verónica Arias Cabanilla, Environment secretary for the Municipality of Quito, the highest authority for environmental policy in the Ecuadorian capital. The city’s environmental policy includes the ‘Cero Basura’ programme, based on the integrated management of resources; this is an ambitious project in which Ineco was responsible for the Master Plan for Comprehensive Waste Management and its legal framework. This coincides with Quito’s selection by the UN to host the Habitat III Sustainable Cities Conference in October 2016. In addition to this, as Verónica Arias points out in her interview, Quito is Ecuador’s most sustainable city and one of the 17 finalists for the World Wildlife Fund (WWF) award for the world’s most sustainable city.

Optimal management of an environmental resource such as the sky is another area of interest that we will address in these pages. Specifically, we have a report dedicated to ENAIRE’s significant technical efforts and investment to guarantee air safety with the highest levels of efficiency. The high concentration of flights in Europe requires a complex new automated air traffic control system: SACTA (so-called for its initials in Spanish) is a series of systems and equipment which ENAIRE is investing over 16 million euros to renovate. Ineco engineers, who are collaborating in the project, offer us a detailed description of the function of these services and what they bring us.

Public policy is key in the necessary move towards more sustainable cities

Also worth highlighting is Ineco’s more than 20 years of experience in supervising the manufacture of trains. This issue features an in-depth article on rolling stock design validation, supervision and testing, particularly in Spain, Chile, Brazil and Colombia, where we have recently renewed our contract.

Finally, I am proud to present the new modernisation project at Chiclayo airport in Peru, where a new terminal is being designed. This large aeronautical project will complement our existing project at Lima’s Jorge Chávez airport. These are big jobs and big challenges in a globalised world where we want to demonstrate the skills and capabilities of Spanish engineering.

The Bus Transport Strategic Plan for the Sultanate of Oman will provide the country with a public transport that is modern, efficient, sustainable and equipped with smart technology. The project involves a complete overhaul of both the supply –including new urban and interurban routes– and management of this means of transport in the Sultanate, where the use of private vehicles is heavy.

Throughout these pages we are privileged to have the perspective of Ahmed Al Bulushi, who is piloting the transition towards the future of the company Mwasalat, the national bus operator of Oman. We also address other works abroad, such as that carried out with Aena Internacional at the airport in the capital of Angola –4 de Fevereiro International Airport (Luanda)– the only international airport in the country for which Ineco conducted the operational safety study. Finally, we have dedicated an extensive report to the aeronautical study conducted for the expansion of the Port of Kaohsiung in Taiwan, where the installation of high-altitude cranes may interfere with international airport operations.

Internationalisation has irrefutably been a key event in recent years, a result of the experience and knowledge acquired over the course of decades developing Spanish infrastructure. In this regard, I am pleased to announce the contract signing with the Costa Rican Ministry of Public Works and Transport for management of the Transport Infrastructure Programme (PIT). It is a new opportunity to strengthen ties with a country that Ineco has collaborated with for years, and that we wish to continue supporting in its development.

We are privileged to have the perspective of Ahmed Al Bulushi, who is piloting the transition of the company Mwasalat towards the future

With Ineco’s new showroom –described on the inner pages– we strive to reflect the know-how of Spanish construction and engineering firms and their experience and impact around the world. The new Centre for Interpretation –which I invite our clients and friends to come visit– was recently inaugurated at our central headquarters in Madrid. It is a visit that I am sure will provide great insight into the scope of our works.

Finally, we complete this space with articles from our experts on highly-specialised projects such as variable gauge facilities –a technology pioneered by Spain–, water studies to protect high-speed lines or Big Data and transport. With the publication of these studies and works we hope to contribute to the dissemination of these new technologies in addition to engaging our readers.

What do you think Spanish technology and experience can bring to our corridor?

I am sure that, under the leadership of Ineco, a Spanish public company with extensive experience in different HSR systems, the consortium will do a fantastic job. I wish them every success in their endeavors. Furthermore, during our visit to Spain in September 2014, we noted that several different systems and technologies had been used to develop the Spanish High-Speed Rail system network, which is the second largest in the world. This knowledge will allow Ineco to provide us with comparative analyses and conclusive technical recommendations.

What was your impression from the visit?

I believe that it was a great success. Our technical experts could see various technologies at work, used to create HSR infrastructures and operate HSR trains. The most interesting things were the gauge changing train, the different traction systems and the signalling and train control systems. The delegation was also impressed by the high-maintenance quality of the tracks and rolling stock.

Coming back to the project, what is the current service level of the existing line between Delhi and Kolkata?

The passenger trains between Delhi and Kolkata currently run at 120-130 km/h. There are various classes on offer to passengers, including First Class Air Conditioned, Two-tier Air Conditioned Sleeper, Three-tier Air Conditioned and the Three-tier Non-Air Conditioned Sleeper, as well as a general, non-reservable class. There are about 17 trains each way every day, which carry around 900-1,400 passengers each.

What kind of comfort levels and technical standards is HSRC currently considering for the new high-speed rail lines?

HSRC is a project development agency whose technical standards are determined by the Ministry of Railways. As part of Indian Railways, there is a specific organisation called Research, Design & Standards Organization (RDSO) which is helping to improve technical standards. Nonetheless, this contract includes a comparative study of the different technologies available on the international market. The most important areas include civil engineering structures, rail tracks, traction systems, the power supply system, the control system, signalling, telecommunications, rolling stock and automatic fare
collection technology. The railway tariffs in India are highly subsidized.

Our technicians were impressed by the high quality of maintenance of the Spanish network

In your opinion, what are the challenges involved in introducing high-speed rail lines with speeds up to 250km/h?

Constructing a new high-speed rail line will bring many challenges. For HSRC, the most complex task will be securing funds, acquiring land and completing the project on time. In any case, the study’s conclusions and recommendations will have a big impact on this question’s answer.

The number of passengers in India will continue to grow –will the Diamond Quadrilateral project address this growth? Or at the very least, will the project reduce traffic congestion?

The HSR lines will really boost the existing network’s passenger capacity, as the operation will be a lot faster, with more passenger trains that will probably be more frequent. This will allow for a reduction in traffic congestion, not only on the railway network but also on the roads.

What kind of economic growth do you expect this new line to generate?

Historically, Kolkata has been a very important port city for eastern India. Nowadays it is the capital of the state of West Bengal. It was the capital of India for a short while, before the country gained independence. Linking Delhi to Kolkata via HSR will give an extra economic boost to an already economically important region.

Spanish engineering and its 3,000 kilometres of AVE has made an impression on the country with one of the most extensive rail networks in the world. A team of engineers and experts from Ineco, Typsa an ICT have been working since 2015 on examining down to the last detail the feasibility study for the future high-speed line that will connect the capital New Delhi with Kolkata.

After years of postponed initiatives, the current government –the National Democratic Alliance (NDA)– led by Prime Minister Narendra Modi, has given a definitive push to implement the high-speed line between its four main cities: New Delhi, Kolkata, Mumbai and Chennai. These four metropolises together have a population of 55 million people in a country with 1,276 billion inhabitants (one sixth of the world’s population). New Delhi has a metropolitan area of around 17 million inhabitants, Mumbai, 18, Kolkata, 14, and Chennai, formerly Madras, around 6 million.

The current government has given a definitive push to implement high speed in the country

Modi has made the industrial development of the country the central focus of his mandate, represented by the ‘Make in India’ campaign, which aims to promote internal production and reduce dependence on foreign countries. To stimulate his economy, the construction of infrastructure, particularly railways and roads, are crucial. Since his arrival to the government in summer 2014, the Prime Minister has implemented the Diamond Quadrilateral Program, a diamond with four corners, which includes the cities of New Delhi, Kolkata, Mumbai and Chennai, separated by more than 1,000 kilometres and connected by modern rail infrastructure: the seed of India’s future high-speed network. The project of this corridor covers 14 states and will serve as an economic driver as well as contributing to rejuvenate the country’s very old rail network, in which every day 18,000 trains operate, around 23 million passengers travel and around 2.6 million tonnes of goods are transported.

Although trains are the mode of transport most used in India –the country is literally knit together with a network of 64,460 kilometres– modernisation of its infrastructure and improved travel times and safety are issues that need to be resolved, which new investments aim to remedy.

Ineco was helped in the awarding of this tender by the support and commercial coordination of the Spain Business Overseas office in India. From New Delhi, its delegate Pedro Sinués has remarked that “the ability and technical experience of Spanish companies has allowed them to achieve the Diamond Quadrilateral tender, which has placed India on the international high-speed map”. “Proof of it –added Sinués– is that the consortium led by Ineco competed against 11 other international consortiums. As such, it becomes more important that two Ineco-led Spanish companies can apply their knowledge acquired in Spain to such an emblematic corridor (connecting what was the capital of India until 1911 with the current capital) and it is important in the socioeconomic structuring of the country”.

The amount awarded is over two million euros and the execution period is one year

The study, commissioned by the state company High Speed Rail Corporation of India Ltd. (HSRC), includes demand studies; prior analysis of route alternatives; calculation of journey times; selection of rail technology to implement (track gauge, track superstructure, electrification, communications and safety installations, etc.); necessary special works; regeneration and resettlement of affected populated areas; environmental analysis; rolling stock and operation and maintenance. Lastly, an economic-financial analysis will be carried out that will be used to determine the feasibility of the new line as well as the most adequate method of funding. The amount awarded is over two million euros and the execution period is one year.

The length of the corridor is around 1,500 kilometres and it passes through cities of great commercial, social and touristic interest, such as New Delhi, Agra (the city of the well-known Taj Mahal), Aligarh, Kanpur, Lucknow, Allahabad, Mughal, Varanasi, Sarai, Patna, Gaya, Dhanbad, Asansol, Durgapur and Kolkata. The line runs through quite a flat area, near the river Ganges, and crosses various rivers and streams, which will require the design of viaducts.

For Félix Zapata, technical director of the project and Ineco engineer, “the work basically consists of analysing the feasibility of its construction, bearing in mind its financial cost and the social advantages that it will bring. Furthermore, we will offer the most appropriate financial model for its implementation”. “The works –adds Zapata– are aimed at achieving speeds and levels of comfort and safety within the modern high-speed standards. For this purpose, we will propose the most appropriate rail technology: type of track (ballast, slab track), electrification, communications and safety installations, rolling stock, specifications for the operation and maintenance of the new high-speed line, etc.”

The extensive Indian rail network has great potential and its own industry, but also many challenges: only 33% of its network is electrified, there are few fibre optic networks, they lack enclosure, stations do not have ticket purchasing systems or safety controls, etc. The project includes adaptation of the current stations to high speed or, failing that, the proposal of the location and preliminary design of new stations. As such, the construction of rail infrastructure with the characteristics mentioned previously will be a very important advancement in the Indian rail network.

In 2014, Ineco conducted a feasibility study on the high-speed rail connection between Haldia and Howrah for Indian Railways, a study carried out with the Spanish companies Ayesa and Prointec, which is part of the projects planned in the Diamond Quadrilateral. Furthermore, in 2009, Ineco provided technical assistance for the works of the Mumbai metro.

“To create a unique symbol for each place”

Bruce Fairbanks, founder of Fairbanks Arquitectos, has accumulated extensive experience in the design of airport buildings since 1996 when he won the tender for the construction of the Madrid-Barajas control tower.

Presently in the world of airports there is a trend to promote the control tower as a symbol, an image that represents the airport and a reference point for the arrival in, and departure from the city where it is located. This trend has created increased interest in architectural execution in the design of control towers in addition to their functional requirements. It is precisely the individuality of these requirements that significantly affects the type of building, such that throughout history there are various examples of “types” of tower designs, which, once designed, were repeated in various airports: one notable case is the leoh Ming Pei control tower. It was designed between 1962 and 1965 with the objective implementation in 70 airports, although in the end 16 were built. The concept of locating in upper levels strictly that which was necessary was developed, putting the maximum amount of functions in the base building, which was adapted to the specific characteristics of each location. As such, the tower could be prefabricated and repeated with standardised equipment, giving the airport network an image of safety since a controller could work in any location without having to adapt. The tower was designed with 5 standardised heights (18-46 m) in accordance with visibility requirements in each location. The control tower’s cab is pentagonal so there are no parallel façades and so as to avoid reflections. In Spain, in the 1970s, Juan Montero Romero, an aeronautical engineer, built a tower, which was repeated in several cities: Málaga, Alicante, Valencia, etc.

To create a landmark, the architect must find within the functionality the characteristics that distinguish one tower from others

Converting control towers into airport landmarks and reference points for cities is a challenge in the work of an architect: creating a symbol, always unique for each location, which meets all of the requirements for the optimal functioning of the tower. The location, the height of the control room, its form and the layout of its structural elements are some of the first elements to define. Control towers typically have a base building and a shaft that supports the upper floors, which are designed to adapt to the control operations. Given the form, with an upper part and a lower part and the height of the type of building, in my opinion it is essential to incorporate the construction process into the design of the tower, and this is what I have done in those which I have designed. This design comes from an analysis of the functional aspects, the programme and the location. To create a landmark, the architect must find within the functionality the characteristics that can distinguish one tower from others and strengthen them to create a unique tower with its own character in each case.

Analysis of four cases

The following examples of control towers show diferente conceptual approaches to design this building type and the elements that diversify its design.

1962. Dulles airport, Washington DC
Eero Saarinen

The Dulles tower has all of the equipment rooms at a height, elegantly assembled by Saarinen with two juxtaposed bodies. The form of the tower is integrated with that of the terminal building, also designed by the same architect.

1992. JFK airport, Nueva York
Pei Cobb Freed & Partners

The upper part of the JFK tower, 97.5 metres in height, contains only the aerodrome control cab and half way up the shaft there is the platform control room, which takes the same form as the upper levels.

1997. Adolfo Suárez Madrid-Barajas airport
Bruce Fairbanks

The Adolfo Suárez Madrid-Barajas control tower had the specific feature of a 400 m² equipment room located at a height. To resolve the transition between the shaft of the tower and the projection, an inverted half sphere was adopted, with a floor for air conditioning equipment being inserted in the support. The octagonal shape defined for the
cab is extended throughout the top of the building, the structural design of a central column and 8 perimeter columns is repeated on all levels.

Another particular feature of the tower is the construction system designed as an integral part of the design. The shaft is built with prefabricated segments assembled in spirals, which, on the inside, contain the service ducts and circumscribe the emergency stairway. The upper floors were built with a metallic structure on the floor and subsequently hoisted onto the shaft. The system allowed the tower to be built in nine months, without using scaffolding.

2004. Barcelona-El Prat airport
Bruce Fairbanks

The functional requirements were similar to those of Barajas, with the exception that a large part of the equipment is located in the base building. The resistant structure is defined independently from the functional elements of the shaft, which was developed as a representative design element. An eight-pointed hyperbola generated from the octagonal shape of the cab holds the upper floors.

The hyperbola links the tower with Catalan Modernism and Antoni Gaudí, who used this form in many of his designs, including on the domes of the Sagrada Familia. The construction system is a representative part of his design. The assembly of the hyperbola, built with prefabricated concrete girders, was guided by a central aluminium structure designed to contain the elements of the shaft. The upper floors were built on land and hoisted into position, supported by the eight points of the hyperbola, consolidating the whole structure when it was under load.

“In the future, it will not be necessary to view operations”

Roberto Serrano has participated in more than 50 aeronautical projects, amongst them, the NET and SAT control towers of Madrid-Barajas airport and the new control tower of Eldorado airport (Bogotá).

Although the first control towers date back to the 1920s (in 1921, Croydon airport in London was the first in the world to introduce air traffic control), it was from the 1930s that they became commonplace, due to the fact that growing aircraft traffic made controlling and managing it necessary. At that time, in which technology was nothing like the current systems, the need to visually supervise aeronautical operations around the airport was met by placing the control room (cab) in an elevated and predominant position of the airport (control tower).

To date, the first steps in designing a control tower involve establishing its site and the height of the cab. Internationally, to meet the viewing requirements from the cab, the recommendations of the Federal Aviation Administration (FAA) are applied. The optimum height and location of a control tower is the result of weighing up many considerations. The view from the cab requires the air traffic controller to be able to distinguish the aircraft and vehicles that circulate in the manoeuvring area, as well as aircraft that fly over the airport, particularly in take-off and landing paths. The objective is to have the maximum visibility possible and avoid the sun, external light sources and reflections from adjacent buildings affecting the visibility of the controller.

Nowadays, technology allows a practically blind landing

With regard to the location, we must consider the potential effects of local weather: flood areas or areas susceptible to fog. Its compatibility with the potential future development of the airport must also be studied, thereby avoiding the need to relocate the tower before the end of its life cycle. Insofar as possible, the tower and its buildings should be located on the landside of the airport, thus avoiding access through the airfield and facilitating the entry of staff. Furthermore, the location should be such that it does not affect the quality of the signals of the airport’s radio navigation aids (ILS, VOR, DME, etc.), or communication systems. The minimum height required for the control tower can be obtained with the aid of the FAA visibility analysis tool, ATCTVAT (Airport Traffic Control Tower Visibility Analysis Tool), in accordance with the physical conditions of the airport.

Once the position and height has been determined, the infrastructure is designed, and generally includes a cab and an antenna field, which, located on the roof of the cab, normally has communications antennas, radio relays, and other electronic and lightening protection elements. Furthermore, there are areas for staff, equipment, power, air conditioning, etc.

In an era in which technology provides information to pilots to allow a practically blind landing, is it necessary to keep air traffic controllers in a high position so they can see these operations? In the future, air traffic control rooms will probably be in buildings that are more similar to those of offices or air traffic control centres than the current towers.

The future has already become reality

2015. Control tower of Örnsköldsvik airport, Sweden

Recently, Örnsköldsvik airport in Sweden replaced its control tower with high-tech cameras. Signals are sent to controllers stationed in Sunvsal airport, located around 150 kilometres away, from a 25-metre mast with 14 high-definition cameras. The high performance of these cameras eliminates blind spots, provides information in rain, fog or snow and, along with a whole series of weather sensors, microphones and other devices, it allows controllers to feel as if they were beside the runway. The Swedish Transport Agency approved remotely operated towers on 31 October 2014. Six months later, the first airplane landed in Örnsköldsvik airport using the remote tower services.

With more than three million travellers in 2015, according to data from the Ministry of Public Works, passengers have given the ‘thumbs up’ to the Atlantic Axis, a railway infrastructure designed for speeds of up to 250 km/h. The renovation, electrification and duplication of existing routes in addition to the construction of new bypasses and several viaducts, bridges and tunnels have made it possible to transition from the old, non-electrified single tracks to high-performance rail infrastructure: greater speeds, capacity, safety, frequency and comfort for passengers who save up to 58% in travel time. In addition to making renovations to the rolling stock, Renfe has also maintained fares and reorganised rail services which are now divided into “express” and “local” services to cover direct routes between large cities as well as between the urban centres near these cities.

Ineco collaborated in the execution of these projects which have revitalised railway transport in Galicia. According to data from the Railway Observatory of the Ministry of Public Works, the A Coruña-Santiago route is one of the top five regional rail lines for traffic in all of Spain. The Businessmen’s Association of Galicia (Círculo de Empresarios de Galicia) considers that the growth in traffic along this route –a growth of more than 90% between 2008 and 2013– is “a fact that must be directly attributed to the improvement in infrastructure and the implementation of a high-performance rail line on this route of the Atlantic Axis”.

Ineco has worked in construction & environmental management & monitoring, project drafting, inspections & structural testing

In April 2015 the Santiago de Compostela-Vigo section was inaugurated –the third of the three sections that make up the majority of this route which represents a milestone in the modernisation of the Galician railway. The territory of this region is characterised by a great dispersion of populated areas: few big cities –concentrated in costal areas–, many small, isolated areas –especially inland– and very rugged terrain. In addition to these characteristics we can also mention the natural geographical barriers that separate Galicia from the Meseta –barriers that have historically stood in the way of constructing land transport infrastructures, both road and rail.

A far-reaching project

The Axis, spanning 155 kilometres, runs along Galicia’s Atlantic Coast and connects the main areas of industrial and economic activity as well as universities, areas which fuel the demand for transport. The pre-study phase is already underway for the connections A Coruña-Ferrol (63.2 km) to the north of the Axis, in addition to Vigo-Border of Portugal (22.1 km) in the far south of Galicia. The route also connects Santiago with Ourense in the east where this section links up with the high-speed access route to Madrid which is currently under construction.

Initial work on the transformation of existing infrastructure into a modern, high-performance, rapid railway corridor began in 2002. Work was carried out in phases and consisted in installing, along the entire route, a double track with multi-purpose sleepers that will later allow for the change from the Iberian gauge to the standard gauge. The line has also been electrified to 25 kV at 50 Hz, and bypasses have been constructed which have shortened the route by almost 22 kilometres. New sections of the line, owing to the land’s rugged terrain, required several structures: 37 tunnels –totalling a distance of more than 60 kilometres– and 32 viaducts that span a total of 14.9 kilometres. The majority of these structures are located along the section between Santiago and Vigo. This was the most complex part of the route to construct and was the last to begin operating, following both A Coruña-Santiago in 2009 and the Santiago-Ourense connection in December 2011.

In addition to the work concerning electrification, platforms and route corrections (bypasses), adapting the line to new, high speeds also required the remodelling of stations at A Coruña, Santiago de Compostela, Pontevedra, Uxes, Villagarcía de Arousa and Arcade-Apeadero, as well as the construction of new stations: Cerceda-Meirama, Ordes, Padrón-Barbanza, Redondela High Speed and Vigo-Urzáiz, as well as the “temporary” Vigo-Guixar station.

Ineco on the Atlantic Axis

Throughout these years, Ineco has offered their services to the Ministry of Public Works, Renfe and Adif in these highly technical and complex activities, just as they did for the rest of the rail network. Ineco was thus responsible for carrying out tasks regarding the management, coordination and surveillance of construction work, the environmental management of different sections along the whole of the Axis, and the drafting of architectural plans (stations) and railway installations (signalling, safety, telecommunications, etc.).The company also conducted a number of studies in addition to inspections and structural load tests, some as exceptional as that of the Ulla viaduct (see IT54)

Ineco furthermore provided assistance in the management and coordination of tunnel construction work, such as the Vigo access tunnel measuring 8,266 metres long which was carried out using tunnelling machinery, and in the installation of safety systems: electrical installations, ventilation, fire protection systems, etc..

Also worth mentioning in relation to architectural work is the drafting of the construction project for the Vigo-Guixar station which, starting in 2011, has operated as the sole station following demolition of the old building while the new terminal was constructed (in the same location). The Guixar station is a two-storey passenger building boasting 1,000 square metres of space, three platforms measuring 285, 165 and 100 metres long for long-distance and regional rail trains, parking, and bus and taxi stops. When the new Vigo-Urzáiz station began operating in 2015, the Ministry of Public Works decided to keep the Guixar station open to freight transport as well as to local trains.

Ineco also carried out a project, completed in 2010, to standardise architectural elements such as marquees, enclosure gates, decorative elements and locks at nine stations: Redondela, Pontevedra, Padrón, Ordes, Cerceda, Uxes, Pontevedra-Universidad, Arcade and Vilagarcía de Arousa. New passenger buildings were also designed for the latter two stations.

The 155-km line has reduced the average travel time between A Coruña and Vigo by 58% and is one of the most widely travelled routes Spain

With regard to new sections of the line, Ineco coordinated the construction of the Ordes bypass in the province of A Coruña, a section that, over a span of just 7.2 kilometres, required two tunnels and a handful of viaducts. The Vilagarcía-Padrón bypass located between Santiago and Vigo stands out for its complexity, reaching a length of 26.1 kilometres. The company provided technical assistance throughout the management of construction work as well as during the environmental management, control and surveillance of several subsections. The bypass was one of the corridor’s most complex sections with seven tunnels and a dozen viaducts, including one which crosses the Ulla river (spanning a distance of 16 kilometres) and another that crosses over the Sar river –the longest on the Axis- measuring 2.4 kilometres.

Ineco also played a role during each of the phases of development of another high-performance railway connection: the line which links the Atlantic Axis to Ourense from Santiago (see IT18 and 44). The company was highly involved in all of the stages of development of this 150-kilometre section of the line, from project drafting to drawing up operations and maintenance plans, as well as during the construction phases including construction and environmental management services, technical assistance, surveillance and coordination services, etc. Since it entered into service in December 2011, the Santiago-Ourense corridor has also contributed to improving railway connections with the Meseta by reducing existing conventional service travel time by 50 minutes.

Spain is the third most popular tourist destination in the world in terms of revenue and for another year it has beaten its own record by exceeding 68 million visitors in 2015, three million more than the previous year. According to all of the analyses carried out, a factor that has benefited the sector is the situation of political instability from 2011 in Mediterranean destinations such as Tunisia, Egypt and Turkey. They all compete with Spain, which mainly receives European tourists: seven out of ten are British, French, German or Italian although, in relative terms, the increase in arrivals from the US and Asian countries is notable. According to Turespaña data, almost 80% of the total number came by air (half on a low-cost airline); a determining factor in this figure is that the Balearic and Canary Islands, for example, which are amongst the most touristic destinations in the world, are islands. As such, in 2015 all of the 46 airports in Spain registered more than 207 million passengers, 5.9% more than the previous year.

During 2015, eight out of ten visitors came to one of the 46 Spanish airports

Besides the two major Spanish airports, Adolfo Suarez Madrid-Barajas and Barcelona-El Prat, which between them accounted for 41.7% with 86.5 million, more than 101.7 million passengers –49.1% of the total– were counted in the 14 airports classified as “touristic”, coinciding with the most touristic destinations: the Balearic Islands, Palma de Mallorca, Ibiza and Menorca; the Valencian community, with Valencia and Alicante airports; Andalusia, with Málaga and Seville; the Canary Islands, with the airports of Gran Canaria, Tenerife South, Lanzarote, Fuerteventura and La Palma; and Catalonia, with Girona and Reus airports.

They all underwent processes of improvement and enlargement in the 2000s in order to increase their capacity, closely linked to the growth in tourism, known as the Barajas Plan, Barcelona Plan, Levant Plan, Málaga Plan, Canary Islands Plan, etc. During this time, Ineco has provided its services to the Ministry of Development and Aena in the planning and execution of the activities. Since 2008 it has also been in charge of the Traffic Forecast Office, which plays a key role in airport planning. A few times a year, a team of engineers and technicians updates the forecasts, and this is carried out with a macroeconometric model called PISTA (Integrated Prognosis of Air Traffic Systems), also developed by Ineco, with a specific methodology based on the concept of a ‘network’ and independent models for the national and international segments, based on significant economic variables. Furthermore, in preparing the specific forecasts for each airport and for the short-medium-term, other factors are taken into account such as competition from other means of transport (mainly AVE), the existence of other airports in the area of influence, changes in offers from airlines (new destinations, greater frequency, new models of airplanes used, etc.), special events (sports competitions, summits, etc.) and others.

Since 2008, Ineco has also been in charge of the Traffic Forecast Office, which plays a key role in airport planning

Not only are volumes of passengers, operations and goods for each airport in the network forecast, but the design values (DHP, design hour passengers; and DHA, design hour aircraft) that are essential for adequate planning of the infrastructure are also considered, since they allow detection of the needs that airports will have and, furthermore, when it will be necessary to carry out the activities. The results of the traffic forecasts are used to prepare Aena’s business and investment plans, as well as to design commercial strategies in airports and, as such, they are very important.

How can we ensure that a taximeter is reliable or that a nuclear facility is safe, that a bulletproof vest is really bulletproof or that the MOT that reviews a vehicle does not act arbitrarily? In Spain, more than 1,600 entities ensure that many products, procedures and services available in the market comply with the regulations of their respective sector. A Spanish government body, the National Accreditation Entity (ENAC), is responsible for authorising who guarantees the safety of consumers and end users. Entities must renew their accreditation every year, demonstrating that they comply with the strict requirements of independence, rigour and transparency that are required for this work.

Rail lines

The wide range of products and services subject to receiving a certification endorsed by an ENAC entity covers any type of production and different types of entities, such as testing or calibration laboratories, inspectors, or certifiers and environmental verifiers from practically any sector: industry, energy, environment, health, agriculture and food, research, development and innovation, telecommunications, tourism, services, construction, transport, etc.

The inspection activity of Ineco falls within the latter, specifically within railway, and in 2009 it obtained its first ENAC accreditation as an ‘independent safety assessor’ with the number 76/EI058. In 2015, it was renewed and extended to the fields of rolling stock, energy, infrastructure, maintenance and exploitation and traffic management. The company has a multidisciplinary team consisting of professionals accredited by ENAC. The work of the entities certified by ENAC, moreover, is not only valid in Spain, but also in the over 70 countries with which it has mutual recognition agreements, including the European Union, United States, Canada, China, Japan, Australia, Brazil, India, United Arab Emirates and Mexico, amongst others.

Why an independent safety assessment?

In addition to rolling stock, since the beginning of rail at the end of the 19th century, the main rail elements related to safety have been signalling systems, in order to avoid the greatest risk of all: collisions between trains. From manual signals to lights, to digital systems and radio without physical signals on the tracks –as is the case for ERTMS level 2–, the different control, command and signalling systems (ASFA, LZB, ERTMS, etc.) have evolved to become more complex and sophisticated, always with the objective of guaranteeing the safe circulation of trains.

The current rail lines –conventional and high speed–, are very complex infrastructure that consist of a large number of elements and undergo very extensive legal and technical regulation that requires a high degree of specialisation by the inspectors. From the time they are planned until they are commissioned, European and international regulations require verification that each and every one of the elements and subsystems work correctly, from the simplest, such as the ventilation of a tunnel, to the most complex, such as software.

For this purpose, two types of safety study are carried out. On one hand, risk analyses, in which threats are identified that could bring the system to a potentially dangerous situation and work is being carried out on mitigation measures or barriers to avoid them. They can be carried out in any stage of the project and seek to detect the weak points of the system. Moreover, and on a higher level, there is the type of study known as ISA (Independent Safety Assessment). Unlike risk analyses, ISA can only be carried out by an accredited entity. They are essential to guarantee for a third party –the operator or rail authority– that a new line or modification of an existing line is safe and can begin or continue to be used.
