This project consists of refurbishing the existing building on Calle García Gutiérrez 1, opened in 1976. It has has a floor area of 9,924 m² spread over two underground floors and nine above-ground.
The whole building was demolished, including the flooring of the current building, preserving only the pillars and metal beams. The horizontal structure of the building was then reconstructed and two new floors were added above-ground.
With the addition of these two new floors, the gross floor area is now 11,472 m².
Work was later carried out on an old three-storey car park under the Plaza de la Villa de París. All of the intermediate flooring was demolished and a very high area was created (courtrooms), as well as another area with two levels.
An underground connection tunnel was constructed between both buildings and separate entrances were created for the public and police vans.
Urban development works were carried out in the surrounding areas.

The old post office building, now known as the Cibeles Palace, is located in the Cibeles Square in Madrid and is a complex made up of two buildings that are separated by a large interior courtyard and constructed on a 44,613-square metre area.
The history of this architectonic assembly goes back to the nineteenth century when the Courts approved the construction of a building for the central headquarters of the Spanish postal service. The awarding of this project was given to the architect Antonio Palacios and engineers Joaquín Otamendi and Ángel Chueca Sainz. The works commenced in April 1907, but the official opening did not take place until the 14th of March 1919 with the presence of King XIII and his wife, Queen Victoria Eugenia and which immediately became a symbol of modernity and progress.
Because of an agreement between the Treasury and the Madrid Council, the most recent and complete restoration took place in 2003 in order to adapt it as the definitive headquarters of the Madrid Council.
For this reason, the restoration project was awarded to the team of architects headed by Francisco Rodriguez Partearroyo and the actual works were executed by FCC. Full remodelling took place, with the building adapted to current requirements and provided with all the necessary up-to-date services and installations, but safeguarding the most outstanding architectonic elements, such as the main vestibule (location for a future museum of the city), the tiled stairways for interior communication (ornamental, handmade Andalusian tiles from the end of the nineteenth century), 771 square metres of glazing rehabilitation, the riveted metal beams, which were previously covered by stone masonry, were left visible so that the significant technical capacity, similar to that of the Eiffel Tower, could be appreciated.
As the culmination of the rehabilitation, the interior courtyard (known as the Pasaje Alarcón), which connects Alcalá and Montalbán streets, was covered by a large, 2,850-square metre glazed dome that enabled it to be used as a large conference room. This glazed covering was proposed in the original Palacios-Otamendi project, but was not actually executed until this latest remodelling work.
- The restoration works were executed while maintaining the original structure of the Palace.
- The Cibeles Palace has become one of the most emblematic buildings in Madrid.
- An innovating and multi-purpose space.
This emergency project that was requested by the Ministry of Public Works was due to a landslide caused by the rainfall in December 2010 and includes the repairs to the Centenary Bridge access by prior stabilisation of the dual carriageway with the construction of a 1.0-metre diameter secant pile wall of up to 42 metre length. This wall was secured by 150-tonne active anchors distributed in two lines. Once the ground was stabilised, the roadway was reconstructed by a "Y" shaped reinforced concrete bridge of six spans cemented over 1.50-metre diameter piles, on which reinforced concrete capping was executed, 1.50-metre diameter piers and the deck consisting of prefabricated, pre-stressed concrete beams with 1.35-metre edge depth.
In addition, other fill-in and drainage works were carried out at the slipped slope foot, with the construction of a channel and the execution of Californian drains distributed all along the slope foot.
With an approximate cost of 15.6 million Dollars, FCC executed the stabilisation of the western access to the Americas bridge, which was an emergency project requested by the Ministry of Public Works (MOP) to improve slope stability.
The project included an investigation survey to establish its design.
The survey consisted of boreholes with core recovery, testing and installation of clinometers and piezometers.
Both clinometers and piezometers are still being monitored.
This stabilisation, which was carried out over an average time of one year, included the following:
• The Installation of sub-drainage, construction of concrete ditches and basin on the mountain side to channel the underground and surface water of the mountain side basin to the Canal.
• Reconstruction of the existing piping for the water exit, from the mountain side to the Canal. A driven, 24-inch diameter, high-density polyethylene (HDPE) pipeline was installed parallel to the existing one, to guarantee drainage capacity from the mountain side to the area bordering the access highway to Veracruz, with special water-collection boxes.
• Slope stabilisation using two layers of launched reinforced concrete, with subsequent installation of 12-metre passive anchors, in a 4 x 4-metre mesh.
• To achieve deep stabilisation of the embankment, a cut-off wall of 1.20-metre diameter piles was constructed that was contiguous with the Veracruz access highway, followed by a crown beam and a 4.9-metre wall. After filling-in the space between the slope and the wall, the stabilisation of the deep embankment fault was achieved by providing weight on the slope foot. In order to achieve stability of the whole works, two rows of active anchors were executed on the wall, which support 150 tonnes per linear metre, with a length exceeding 50 metres.
• The hidden wall face was waterproofed by constructing a ditch at its foot to collect water underground water circulating through the underground drainage. A ditch was executed along the upper part of the wall to collect surface water.
• Californian drains were installed from the crown beam, with six-metre separation and length exceeding fifty metres, with a five-degree inclination.
• The final wall appearance from the Veracruz roadway was obtained with an apron from the pile cut-off wall crown beam to the water collection ditch at the roadway foot.
• The final access appearance was obtained by injection below the grade line, asphalt paving, together with lesser operations.
• Reforestation and seeding to control erosion.
This main aim of this project was to expand the building's surface area by adding two basements - the access level and the first basement. In order to do so, the existing foundations were underpinned by transferring them onto deeper ones.
The other objective consisted of fully refurbishing the existing floors: ground, first and second, by reorganising the space to insert exhibition rooms, open services to the public and internal museum services.
The project is structured into several areas of action:
