Inaguration of motorway A-33 section between Yecla and Jumilla

Last 5 October, the Motorway A-33 section between Jumilla and Yecla was opened to traffic. In December 2014, the Minister of Development at the time, Ana Pastor, placed the work’s first stone.

Of the 23.4 kilometres constructed, 7.5 of them were built by CHM in UTE with Padelsa, with a 18,277,432.52€ budget (VAT excluded). Works were completed 7 months ahead of the initial deadline set by the Spanish Government.

The three sections open between Jumilla and Yecla join the two sections between Blanca and Jumilla, put in operation in August 2012, which will continue from Yecla to La Font de la Figuera. When all of the A-33 sections are in service, the motorway will benefit traffic, connecting Medio and Alto Vinalopó with Murcia and Valencia.

In addition to other attendees, the Minister of Development, Mr Íñigo de la Serna, the President of the Region of Murcia, Mr Fernando López Miras, and the mayor of Yecla, Mr Marcos Ortuño, were present at the inauguration.

CHM awarded renovation of the Calpe-Teulada stretch of Tram line 9

Ferrocarrils de la Generalitat Valenciana (FGV) has awarded the contract for line renovation and infrastructure improvement work on the stretch of Tram line 9 between Calpe and Teulada stations to the temporary joint venture formed by CHM plus FCC and Convensa. The intervention is part of work being carried out by the Valencia Government Department of Housing, Public Works and Territorial Vertebration to modernise the line. The contract is worth 15.7 million euros with a 12-month execution period and includes work on tunnels, bridges and other structures along the line. The renovation of more than 12 kilometres of tram line will result in better safety, greater user comfort, increased lifespan for the line and a reduction in maintenance.

Last October, the joint venture formed by CHM and Tecsa was also awarded a contract worth close to 4 million euros for work on another stretch of Tram line 9 between Benidorm and Dénia.

CHM Infraestructuras receives the National “Best Environmental Practices” Prize

reconocimiento a la sostenibilidad

The Spanish Association of Manufacturers of Asphalt Mixture (ASEFMA) hands out the only award recognising the sustainability of asphalt surfaces.

The project “Reflective surfaces for mitigating climate change”, developed by the R&D+i team at CHM Infrastructuras, received the “Best Environmental Practices” prize on 30 May. This is the most important national accolade in the sector, and is awarded by the Spanish Association of Manufacturers of Asphalt Mixture (ASEFMA). The prize was accepted in Madrid by Vicente Vilanova, president of CHM.

The jury, comprising members of the Technical Committee of the 12th National ASEFMA Seminar, evaluated the projects entered in this competition, scoring them based on their originality, innovativeness, impact on the sector and their benefits to the environment. They also assessed the presentation of the practice, printed materials and report. The three finalist projects (CHM Infraestructuras, Composan/CIRTEC and Alberto Moral/UAX) were deemed to be the best environmental practices developed in Spain in the asphalt mixture area.

CHM’s research has found that reflective flooring helps to reduce CO2 emissions because of its energy-saving impact on climate control and lighting in cities, by mitigating the effects of overheating during summer, which leads to healthier, more comfortable conditions for pedestrians.

The “Best Environmental Practices” Prize is a sector initiative whose purpose is to raise the profile of the significant investments in R&D undertaken by companies to improve asphalt mixtures, to create more sustainable, environmentally responsible materials that add technical value and are economically viable. The prize reflects the growing environmental sensitivity among asphalt manufacturers and those who produce, transport and apply their products.

The section is 9.55 kilometres in length and passes through the municipal areas of San Isidro, Granja de Rocamora, Callosa de Segura, Cox, Redován and Orihuela, in the Province of Alicante.

The works consist of the following main elements:

Callosa-Cox viaduct with a length of 742.75 metres and widths varying from 14 to 34 metres for the double-track main line, two side lines and pedestrian platforms of 6.30 metres width.

Redován viaduct, a hyperstatic viaduct of 589.10 metres in length, 14 metres in width and 16 spans of 29 to 37.65 metres.

Elevated walkways over platform (4), three of them with a width of 8 metres, one with a width of 15 metres and length of 476.80 metres.

Callosa-Cox station is located on the Callosa Cox viaduct, with the passenger building and station car park under the viaduct and the platforms on top. The works for the station include the building, platforms, facilities, parking, urbanisation and reorganisation of the necessary access roads.

Callosa tunnel (which is immediately after the Callosa-Cox viaduct) has a length of 2,050 metres, a free width of 8.60 metres and an interior free space of 85 square metres, crossing the Sierra de Callosa and the “Sierra Callosa de Segura” LIC (Area of Regional Importance). In addition to the railway tunnel, two auxiliary emergency evacuation tunnels have been constructed (parallel to the main tunnel along its right side), with safety areas in each tunnel entrance.

In order to maintain existing railway traffic, a diversion to the current railway line has been constructed, of conventional width, over which the railway traffic will run until the new line is opened.

In addition to the one-off units, works have been done for the stabilisation the ground, drainage and gravel columns, foundations with in situ prefabricated piles, embankments, causeway, platform preload, transverse drainage works, relocation of services, environmental restoration, etc.

CHM is undertaking an ambitious infrastructure project in Algeria

CHM Obras e Infraestructuras, in consortium with other Spanish and Algerian companies, is carrying out one of the most ambitious civil engineering projects in the Western region of Algeria. The new Pénétrante de Mascara Autoroute connects with the highway (East-West) and covers 43 kilometres with three lanes in each direction.


The contract awarding body for this project is the National Highways Agency, owned by the Ministry of Infrastructure of the People’s Democratic Republic of Algeria.


The project involves great technical difficulties owing to the complex geography in that area. Work entails moving approximately 6 million cubic metres of excavated material, 4 cubic metres of embankment, 250,000 cubic metres of concrete and 50,000 tonnes of passive steel. The highway also has 3,750 metres of structure on the main carriageway and 120 metres on overpasses.


The project budget stands at 19,408,747,923.78 Algerian Dinars, equivalent to €180,857,061.74. Work is expected to be completed by mid-2018.
