BAC, technical assistance in the dismantling of tolls

The technical assistance works are part of the actions planned for the dismantling of the toll infrastructures once the concession has ended.

BAC participates as technical assistance in the dismantling of 3 tolls on the C-32 motorway and a toll on the C-33 motorway, as well as in the adaptation of the current toll platform on which the new circulation roads will be restored that provide continuity to existing cross section.

The 4 tolls are:

  • Mollet del Vallès trunk toll, located on the C-33 and consisting of 18 lanes.
  • Vilassar de Mar trunk toll, located on the C-32 and consisting of 14 lanes.
  • Arenys de Mar trunk toll, located on the C-32 and consisting of 30 lanes.
  • Trunk toll of Santa Susanna, located on the C-32 and consisting of 26 lanes.


This emergency work only includes the dismantling of the central lanes (3 + 3), while the rest of the toll plaza will be pending until the approval of the construction project that will be promoted shortly by the Generalitat de Catalunya.

BAC new official supplier in UTM by RINA and ABS

BAC expands its services in thickness measurement in naval structure adding the certification as supplier for the classification societies: RINA and ABS.

The department of NDTs in naval structure of BAC has increased its services, adding the certifications for thickness taking by ultrasound (UTM) of the Italian classification societies (IACS) RINA (Italian Navale Registry) and American ABS (American Bureau Shipping) . This certification does not have any restrictions on the weight or size of the vessel, which enables BAC to be able to carry out this work in any vessel that has either of these two societies as a classification society.

These certifications are in addition to those that BAC has been renewing for more than 10 years, currently having the distinction of official supplier for taking thickness through NDTs with the following IACS:

  • Bureau Veritas
  • Lloyd’s Register
  • Det Norske Veritas (DNV GL)
  • RINA
  • American Bureau Shipping (ABS)

This certification allows us to carry out our work in 80% of all ships that transit worldwide, being able to offer our services anywhere in the world.

Realización Ensayo no destructivo

Non-destructive tests in the evaluation of structures

Abel Domato has been part of the team of experts that has travelled to Beirut on behalf of the International Atomic Energy Agency

This September, a group of the IAEA Experts, including Abel Domato, has participated in the mission organized  to train Lebanese counterparts on the application of NDTs (Non-Destructive Testing) in the evaluation of buildings affected by the explosion that occurred in Beirut last year. . The mission was composed of three experts, Dario Foppoli (Italy), Nor Azreen (Malaysia) and Abel Domato, accompanied by official IAEA personnel.

After a disaster like the one in Beirut, the deflagration, which had an effect similar to that an earthquake, the evaluation of structures is one of the most important parts of the reconstruction process. The contribution of the ENDs in this field is very important since it allows obtaining a large amount of information to be analysed later. As in other IAEA cooperation missions in which Abel Domato has participated in Albania, Mexico, Ecuador, Peru or Costa Rica, technical cooperation was provided to local governments, advising on the methods to be applied and the training of the local technical staff.

BAC is accredited as EC PCA for the measurement of acoustic insulation

With the authorization as a collaborating entity, it is intended to guarantee the quality of the technicians and of the companies dedicated to the measurement and evaluation of noise pollution

BAC has achieved accreditation as a control entity in the field of noise pollution prevention (EC-PCA), from the Generalitat of Catalonia, in the field of “measurement of the acoustic quality of buildings (QE)” and the following subfields:

  • Measurement of acoustic insulation to airborne noise between premises
  • Acoustic measurement of impact noise.
  • Measurement of acoustic insulation to airborne noise for facades.

With the qualification as a collaborating entity, it is intended to guarantee the quality of the technicians and of the companies dedicated to the measurement and evaluation of noise pollution, having to comply with organizational and quality requirements, as well as technical requirements with respect to personnel and the availability of equipment.

Decree 176/2009, of November 10, which approves the development of Law 16/2002, of June 28, on protection against noise pollution, creates the figure of entities for the prevention of noise pollution as entities employees of the Administration.

BAC i Ventayol realizando sondeos geotecnicos

Geotechnical borehole for the integration of the railway in St. Feliu de Llobregat

The Minister of Transport, Mobility and Urban Agenda, Raquel Sánchez, has visited the geotechnical borehole that Bac i Ventayol Geoserveis drills in Sant Feliu de Llobregat for Acciona.

The Minister has been accompanied by Teresa Cunillera, Government Delegate in Catalonia; Lidia Muñoz, Mayor of Sant Feliu de Llobregat, and Isabel Pardo de Vera, president of ADIF, as well as other authorities.

The Railway Integration project in Sant Feliu de Llobregat involves burying the track in a 1.9 km section, of which about 1 km consists of a mine tunnel under the current route, with a maximum depth of 24.6 m under the surface. The construction of a new underground railway station is also contemplated, and logically the suppression of the existing level crossing, which has been the source of numerous accidents in the past.

Bac i Ventayol Geoserveis drills 7 geotechnical borehole at depths between 25 and 35 m, with the execution of permeability tests, and the performance of precision pressure tests. This test is programmed in advance, and then it is fully controlled by the GeoBox computer equipment, although the specialist geologist has full control of the process at all times. It is a Ménard type equipment, which can reach pressures of 100 kg / cm2.

The main objective of the campaign is to accurately determine the resistance and softening parameters –strain softening- of a layer of low resistance silts detected in previous campaigns.

Equipo BAC Madrid. Staff directivo y equipo de control de la obra de la estación del metro

The new Gran Vía station of the Madrid Metro has been inaugurated

BAC has been the company in charge of controlling the modernization, expansion and improvement works of the Madrid Metro Gran Vía station with a work budget of more than 10 million euros.

BAC has completed the inspection, surveillance and control works of the “Modernization and Implementation of Lifts in the Gran Vía Station of the Madrid Metro” works, financed 50% with ERDF funds. These works have represented a great change in the structure of the station that now has a vertical axis with connections between the three new levels, L1, L5 and Cercanías.

The president of the Community of Madrid, Isabel Díaz Ayuso, has inaugurated the new station, which is the most modern of the suburban network in terms of technology and accessibility. “It will be the first 4.0 station in Spain and is, therefore, also one of the pioneering stations in Europe.” About 66,000 passengers are expected to pass daily through the station.

Autoridades durante la inauguración de la obra de la estación de metro de gran vía

The works, which have lasted for almost three years, have been coordinated by Metro de Madrid, the Directorate General of Infrastructure and Adif, which have collaborated together to launch one of the most ambitious projects in recent years, which connects the Puerta del Sol axis (with Metro and Cercanías-Renfe) and Gran Vía, two emblematic spaces of the Madrid capital.

Great job Almudena Vecino, Ricardo Planchuelo, Dámaso Picazo and Adrián Abad, with the support of the BAC technical office.
