Duggi-Salamanca Health Centre - Tenerife

Date: 2008-2010
Type of work: Building

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.

Toledo Hospital

Date: 2008-2010
Type of work: Building

Construction of the structure of Toledo Hospital, awarded in phases with a total of 360,000 m2 of slabs. The fi nal phase under construction has 180,000 m2 and uses more than 10,000 m2 of Alumecano, 2,000 m2 of Alisply equipment, between curved and straight sections and, for the fi rst time, Alsicar is being used to move elements between floors and has been very well received on the job site. The project was designed by the famous architect Alvaro de Siza and features special elements such as exposed curved walls, which are being built using Alisplay system, and joint drawings on all the walls to matching the 7.20 m pillar interaxial distances.

Data centre in Cerdanyola del Vallès - Barcelona

Date: 2009
Type of work: Buildings

Project of 16,000 m2, with 4 slabs of 4,000 m2 each, with a height of 5 m between slabs, except for the fi rst slab which has 6 m. The structure of the building is made up of post-tensioned oneway slabs with a thickness of 50 cm, resting on hanging beams with a section thickness of 90 cm and 90-cm capitals.To carry out the work, the multiform system was used in combination with Alsina A-lite props owing to the need for a fair-faced fi nish, the tight deadline and the need for the formwork to have a high load capacity.

Ibermática Pavillion - Vizcaya

Date: 2009.
Type of work: Buildings

The Ibermática Pavillion is an offi ce building in a technology park in Vizcaya.Alsina executed several double-height suspended fl oors with beams. The system used was the CL-40 Shoring System from Alsina whose versatility and lightness was key for a quick and effi cient execution. Alsina was responsible for the multidirectional assembly and the customer was very satisfi ed by the productivity of the system.

Hospital in Viña del Mar - Chile

Date: 2009.
Type of work: Buildings

Expansion of the Hospital of the coastal town of Viña del Mar (Chile) with propping of metal beams and anchors. A large health centre with four fl oors above ground and three basement floors. For the work the Alisply system from Alsina is being used in various ways: Alisply Walls and One-sided Walls for the execution of walls against terrain. The fi rst basement level was executed without a crane, moving all the formwork by hand, which indicates the lightness of the Alsina systems. For the piles, the Alispilar system was used combined with Alisply Walls.The slab was executed with the Vistaform Slabs system. The height of the slab is 2.8 m on average. At the end of the work the customer was very pleased with the versatility of the Alsina walls system.

Krakow Technological Park - Poland

Date: 2008
Type of work: Building

The new Technological Park of Jagiellońskie Centrum stands just in the heart of Krakow (Poland), a complex of modern facilities called to become one of the technological engines of this Polish city. For the implementation of the structure the company FORBAU SP assigned the project to Encofrados Alsina. Approximately 5.400 m2 of Alumecano system were required to carry out the structure. The columns were implemented with Alispilar system and Springform was also used to allow the implementation of different phases.

Lloret de Mar Casino - Girona

Date: 2009
Type of work: Building.

This singular building with high finish black concrete is located in the Mediterranean area of Lloret de Mar, situated in Costa Brava (Girona).
The main structure consists of post-tensioning walls and beams with variable edge of 3 and 5 m.
The shoring of the beams has been realized using Shoring System AR-80.
El apeo de estas jácenas se ha realizado utilizando Cimbra de alta resistencia AR-80.
This shoring system supports a post-tensioning slab, a ´sandwich´ type, that must be re-shored to support the loads of the superior beams.
The building shape consists of an annex module to access the main space, formed with inclined to 2 sides 45-degree slope slabs, respecting the horizontal level.

Oceanic Centre – Valencia

Date: 2004
Type of work: Building

Complex including a hotel, a shopping centre and an office building located opposite the new City of Arts and Science of Valencia. Construction in which the dominant slab structure consisted of 30-cm slabs, made in a profitable and efficient manner using our Alumecano system: a temporary slab system that optimises rotation cycles and ensures a faster working pace for the project. In the end, a total of 130,000 m2 of slabs were built.

Contemporary Art Museum of Aragon – Huesca

Date: 2003
Type of work: Building

In the construction of this unique project by renowned architect Rafael Moneo, Alsina systems were able to successfully deal with the sinuous structure of the building. The Vistaform Curve system was essential for dealing with the changes in the radius of the walls and the architectural concrete finishes required for the project.

Millennium Tower, Sabadell – Barcelona

Date: 2002
Type of work: Building

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.
