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

Date: 2008-2012
Type of work: Civil Work

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.

Arico´s Environmental Complex - Tenerife

Date: 2007
Type of work: Civil Work

Running a closed pipe using a domed structure. The closed pipe stretch had a 30 m length and the canopy had a 65 cm thickness.
The roof´s curvature ray was 3,5 m. The pipeline stalks were executed with Alisply Wall and the vault’s formwork support was performed using CL-40 Shoring System with a 1,09 x 1,09 confi guration. The vault´s formwork was performed with a network of HT-20 beams using the Alisán´s panels as a formwork surface. The advantage on using
the Alsina´s planned solution is the use of standard material, preventing the transport of specifi c material to vaulted structures in Tenerife. The client appreciated the wooden beams HT-20 lightness against metal beams.

Terrassa´s Can Roca station - Barcelona

Date: 2007/09
Type of work: Civil Work

New railway station construction with Alsina systems in Can Roca-Terrassa. In total there are four projected plants. The first plant, a 60 m long and 50 cm thick slab, runs with CL-40 Shoring System and Alsina table. This fi rst plant consists of 20 m opening with intermediate circular columns in the central vain and an average height of 7,5 m. The higher plants, with approximately 30 cm thick slab and 60 m length, are carried out with the Alumecano system
because of its high effi ciency and productivity.
Once the fi rst plant was fi nished, there were used half of the tables to prop up the higher plants during the implementation process.

Andorra Cement works - Teruel

Date: 2007/08
Type of work: Civil Engineering

Alsina collaborated in the implementation of the silo of the Andorra Cement works, in Teruel. The most complex phase, technically speaking, was the implementation of the concrete cone. It should be highlighted that the implementation with Shoring Systems of a cone of this type is very difficult. Alsina’s Technical Department proposed a polygonal type implementation. The phenolic boards were cut in a triangular shape as per the required dimensions. To produce the cone shape these phenolic boards were placed on secondary wood beams forming a triangle. Some of these secondary beams were levelled with wood wedges in order to give the phenolic boards the necessary curvature and getting so the final cone shape. All this material rested on the CL-40 Shoring System.

Thermal station at the Besós - Barcelona

Date: 2008
Type of work: Civil Engineering

Two levels of high load beams are implemented in two phases. In a first phase the first level is implemented with the Shoring System placed under the beam. The C-240 Climbing Section is used for the outer piles, helping in this way to set the working platform.
In the second phase the whole Shoring System is raised up to the desired level and the same solution is chosen for the outer piles.
Apart from supplying the material Alsina was also responsible for the assembly of the system on site. During approximately two months an average of six operators worked in the assembly and disassembly of this formwork system.
The final result was satisfactory and the project was finished according to its completion periods.

New Terminal Building, Pamplona Airport - Spain

Date: 2008
Type of work: Civil engineering

The works consist of the implementation of 15.000 m2 of Alucubetas with different rib widths (16 and 20) and different dome heights (30, 35 and 40). From these 15.000 m2 of works, 3.000 m2 were built with 40 cm + 15 c.c. N20 Alucubetas system and a free height of 8,60 m. With the aim of avoiding the double propping of those 3.000 m2 it was decided to place the domes on a Multidirectional Shoring System. In addition to these 15.000 m2 the roof was formed by 90x200 girders with a total height of 12 m, for which 30.000 m3 of shoring system were needed. Due to the complexity of its construction it was required to design special solutions along the development of works.

Type of work: Civil engineering

Alsina Systems: Alisply Walls, Alumecano, 5 m Posth-shore and 9 m Aligner.

A new treatment plant for urban solid residues of the province of Barcelona, where the main systems used were Alisply Walls, a modular system for wall formwork using large scale panels, giving a high quality finish. The performance of the system on the build, the speed of the assembly, the finish of the wall and the wide range of accessories make Alisply an ideal system for this type of site.

Torredembarra Lighthouse - Tarragona

Date: 1999
Type of work: Civil engineering.

The Torredembarra lighthouse is, with a total height of 59 m, the tallest lighthouse on the coast of Catalonia. This octagonal white-concrete tower was built using Alsina´s standard wall-climbing formwork systems. To successfully perform the formwork, Alsina designed a special solution that consisted of adapting the Alisply Walls formworking panels and the Climbing Platform system. The challenge was to overcome the octagonal geometry of the building and concrete the inner and outer faces of the climbing formwork at the same time. Alsitec technicians were on site during the work to advise the project managers, who showed their satisfaction with the construction of the lighthouse.

Marseilles integral waste treatment plant – France

Date: 2007/08
Type of work: Civil engineering

Located in Marseilles (France), it is one of the first plants in Europe to combine biomethanisation and incineration processes in the same facility (located on a 180,000 m2 plot). This plant will process around 600,000 tonnes of waste a year, produced by a total of 1 million inhabitants. The plant consists of several buildings and large facilities, including the waste collection pits, a three-line processing plant, two biomethanisation digesters, an incinerator and a grinding turbine.

The main building of the plant has a maximum height of 21 m, built using the C-160 Climbing Platform. A large number of Site stair towers were installed in this structure at great height to make it easier to change between building levels. A large amount of CL-40 Shoring system was used in this building for making slabs at height. Also important are the digesters made using Alisply Circular, with a maximum height of 25 m, using the C-240 Climbing Platform. During the project, Alsina fully complied with the demanding safety requirements.

La Paloma Biomethanisation Plant – Madrid

Date: 2007/08
Type of work: Civil engineering


The Alsina C-240 Climbing Platform system allowed for a quick movement of the unit formed by the wall plus the climbing platform. When concreting at a height of 5.40 m, having a stripping carriage considerably reduced the number of crane movements required. This made it possible to achieve highly productive working rates during the tasks of formworking and stripping the systems. The greatest savings in crane use were made when building the circular digesters at a height of 20 m.

BP refinery extension – Castellón

Date: 2007
Type of work: Civil engineering


The structure of the building consists of three levels of thick girders, one intermediate slab and one very thick top slab. To save time and money, Alsitec suggested first shoring the beams and then clearing them in successive phases to leave only two beam levels shored, stripping the shoring from the first level to concrete the third level. The proposed solution does away with the need to shoring the entire structure since it uses the strength of the previously built structure, so that the beams formworked in the first stage transmit their loads to the columns, absorbing the loads from a considerable part of the levels that were built in successive stages. The cantilever of the top slab required formworking with shoring at a considerable height, leaving striking views of the façade during the formworking stage.

Sabadell Airport Control Tower - Barcelona

Date: 2006
Type of work: Civil engineering.

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.
