Mecanoconcept: Non Residential Facilities

New BBVA Bank Headquarters in Madrid - Spain

The site BBVA has procured for its new headquarters is located on the periphery of Madrid. It is surrounded by streets of newly erected offices, commercial buildings, and residential developments. It is a “site without qualities”, a desert-like place. We propose the creation of an artificial garden, an oasis, evolving from inside out—a place that establishes a balance between the natural environment and the buildings, and functions like a small city. Architects Herzog & de Meuron have designed this new headquarters for Spanish banking group BBVA.
A linear structure composed of three-story buildings, alleyways and irrigated gardens is laid over the entire site like a carpet that follows the topography. Analogous to an Arabian garden, a cool, moist, fresh microclimate is created. Each workspace has a “green view”. The layout, with its horizontal branches, is more appropriate to today’s working world than open-plan offices, in which an employee feels like a number.

In order to make the BBVA stand out in the skyline of the capital, the carpet is cut out in an approximate circle and tilted upwards: the result is a plaza and a slender, disk-shaped tower. Plaza and Tower anchor the complex and provide orientation. The Tower, containing offices with views across the city and the Sierra of Madrid, contributes to the diversity of the workspaces.
Alsina is already supplying formwork equipment for the execution of one of the horizontal buildings. At this stage of the site are being implemented a total of 180,000 square meters of concrete structure.
Later the engineering expertise supplied by Alsina will help to execute the singular tower with circular shape. To emphasize the human and technical capacity of Alsina team joined the allowed range of solutions to solve the complexity of this unique project.

Carthage College in Wisconsin, USA


We provided the shoring system for 6 levels of shoring for the student housing (dorms). The engineer determined 4 levels of reshoring was required. We came up with an affordable shoring solution utilizing HT Wood beams as joist and stringers and A3 post shores.
This solution allowed to bid more aggressively and obtain this project. There was a cantilevered beam along the perimeter of the building.
Because the ground was unstable we were unable to shore down to the ground. Instead we used C240 as a wall bracket.

The Director of the Basketball World Palacio Multiusos de Gran Canaria, Spain


The Director of the Basketball World Cup, Miguel de la Villa, accompanied by the people in charge of the construction, visited the works being carried out in the Palacio Multiusos de Gran Canaria to which Encofrados Alsina supplies equipment for the construction of the grandstand slab.
This project is of great importance to which the company has sent large amount of formwork materials: AR-80 Shoring System, Multiform, Alumecano, Alispilar and the steel mesh barrier.
The most distinctive feature of this work is the modular formwork finishing of the grandstand “Trough” concrete slab designed by the company. “Trough” is what is called the lower slab of the pavilion grandstand (due to the truncated inverted pyramid shape with a rectangular base similar to the utensil used to knead bread).
The formwork system for the trough shaped stand for the Palacio Multiusos de Gran Canaria is made up by a Multiform Alsina type structure, which adjusts to the geometry of the slab.
The Multiform structure stands on CL-40 Shoring System of Alsina’s Multidirectional System type. Each system module, once assembled, is manually moved by rack carts. In this way, the total amount of shoring system assembled and disassembled is minimized and the time spent on the lifting equipments is optimized.

Extension of Museum in Lugano, Switzerland


Located about 80 km from the city of Milan (Italy), the Lugano Museum is formed by an area of 168,000 cubic meters.
The building structure consists of some highly remarkable architectural enclaves. The building Hall consists of four bearing piles and roof with unidirectional beams of prestressed concrete. Museum building is formed by floors with beams to allow the light to pass through. And finally, the theatre is formed by solid structures of reinforced concrete and prestressed concrete.
It is precisely on the walls of the theatre where the most complex technical solutions have been implemented. The theatre wall consists of one external wall, executed with the C-160 and C-240 Climbing System and another 30 cm thick wall which closes the whole space and which had to be made with the one-sided climbing system Multiform (MF1). The climbing platform was 3 mts, due to the pressure it had to face, and was formed by 3 comprehensive Multiform brackets.
The climbing system operation assumed the connection of the MF beam to the concrete wall, with dywidag bars, nuts and plates in the holes of the panels. This beam was connected to the vertical ones with the assembly of the MF Climbing system. Finally, the Alisply wall panel used was 3x2, to reduce the pressure of concrete over the system.

Banco Santander Communications Tower, Spain


Alsina has made the Communications Tower on the Provincial Data Center of Banco Santander in the Spanish town Solares in Cantabria. For this site we have had to design a custom solution to solve the body form of the tower which consists of a hollow concrete element.
The Data Processing Centre (CPD) of Banco Santander will be ended at November 22th of 2011, and operational in the first quarter of 2012. This facility has been built in the industrial area Marina y Medio Cudeyo, placed outside of the town of Solares. The final investment on this site is around 240 million €, including place, civil engineering works and technological equipment.
When the CPD will be operational in 2012, 250 people will have a job and this facility will be connected with other large data centers of Banco Santander located in Madrid, London, Mexico City and Sao Paulo. The CPD is the most advanced technology of the five banks with operations in the world "and will be a reference for those who can build in the future."
This is a high-security facility, built following the highest international standards to address all hazards, electrical faults, bad environmental, earthquakes and other external aggressions. This facility will operate continuously throughout the year.
Alsina has realized the part of the site that corresponds to the Communications Tower CPD. For this purpose the special parts department of Alsina has had to design a custom solution to solve the body of the tower that consists of a hollow concrete ovoid. The tower had a final height of 55 m, it was performed in 12 stage with climbs of 4.5 m in height, the wall thickness is 60 cm.

Miami Ballpark-Marlins Stadium - U.S.A.


Ambitious project in which Alsina was the company chosen to make several technically complex columns (specifically the two on the northern end and those on the southern end of the stadium) with angled double-sided walls. The columns on the northern end ware 48 m high with a total of 10 applications, while the columns on the southern end were 38 m high with 9 applications. In the first two applications of the columns, a combination of one-sided wall frames was used with the Alsina multidirectional system. After the second application the new T1C Climbing System designed by Alsina´s R+D Department was used. The Miami Ballpark is the first project in which this novel system was used, which can be applied in the following cases: one-sided straight and angled climbing walls, dams, two-sided angled walls (as is the case of Marlins Stadium) and two-sided straight walls with frame spacing up to six meters. The client was fully satisfied with the productivity and effectiveness of the new T1C Climbing System.

Duggi-Salamanca Health Centre - Tenerife


Construction of the retaining walls. Due to design requirements, the fi rst set-up (in which the M1C angle brackets were used) was made at a height of 2.7 metres. The rest of the set-ups (in which the C-160 platforms were used) were limited to 1.8 m. This height restriction did not result in inconvenience for the client since the wall is so thick that its construction was relatively slow (in total around 3,000 m3 of mass concrete used). The angle brackets were assembled with an inclination of 10º. Alsina recommended the use of concrete wedges, which turned out to be very successful.

Millennium Tower, Sabadell – Barcelona


Emblematic office building located on the Eix Macià in Sabadell. For the correct construction of this building, with a height of more than 90 metres, important aspects such as construction times and the amount of material required were taken into account. From the start, Alsina suggested using its Alumecano system for formworking the floor slabs. Alumecano is a slab formworking system designed to optimise rotation cycles and help maintain the working pace demanded by the project managers. For this purpose, Alumecano was designed with structural elements made from duralumin. The design of the components and the work organisation made it possible to obtain a very profitable work output.

Mieres Health Centre – Asturias


Several determining factors affected the setting out of the Multidirectional system. First of all, we needed to plan for its support at two different heights, since there was an intermediate floor. One of the parts had a clear height of 12 m and the other was approximately 9 m, so the setting out needed to adapt to this height difference.
The second determining factor was the metal columns installed prior to setting up the shoring system. These columns consisted of groups of three metal tubes, joined at the base and opening in a triangular shape towards the top slab (meaning that the metal columns were installed straight, diagonally or crossing the middle of the shoring system). This was of utmost importance when setting out on the main floor, when placing the towers, and later when installing the frame of girders, in order to clear the metal columns. Tubes and flanges were supplied so that, once the towers were in place, these metal columns could be fixed at the top so that no movements that might shift the columns would occur when concreting the slab.

Sabadell Airport Control Tower - Barcelona


Alsina designed a special solution that consisted of using the corners of the One-sided wall at 6 m to install a platform that could be used for formworking a slab at height. This slab had a thickness of 40 cm, approximately 17 m from the ground, overhanging the tower by 3.5 m. The conventional process for building this type of structure is to use shoring system, but it was necessary to provide access to the tower, meaning the entire perimeter of the tower could not be blocked with the metal rods of the shoring system. For this solution, Alsitec designed a special anchor for the wall, calculated to withstand the shear stress and pressure to which it would be subjected.
