Structural Restoration La Pedrera

Sector: Building
Client: Francisco Asarta and Robert Brufau
Years: 1994 – 1996
Description:

 

Architectural and structural design for the rehabilitation of one of Antoni Gaudí’s masterpieces, the emblematic Casa Milà building (also known as La Pedrera).

The design followed the methodology of the original project designed by Gaudí, based on the catenary method, although it benefited from modern technologies. These made it possible not only to understand the source of the problems needing repairs, but also to be true to its unique spirit without compromising the concept of the original design.

CCIB - International Conference Centre of Barcelona

Sector: Building
Client: Josep Lluís Mateo
Years: 2002 – 2004
Description:

 

New conference centre for the city of Barcelona. Its design included the creation of a 150 x 90 metre space that has large box-section portal frames instead of columns. These frames with lattice walls and two pins at the base were placed every 15 metres.

Tensions arising between two supports are absorbed by post-tensioned tendons that join them together in a longitudinal direction. There is a system of beams and battens supporting the composite steel deck slab for the roof.

Hotel Arts Barcelona

Sector: Building
Client: Skidmore, Owings & Merrill (SOM) and Frank O. Ghery
Years: 1988 – 1993
Description:

 

Design of one of the first high-rise buildings in the city of Barcelona in collaboration with the studios of SOM, Frank O. Ghery and GCA. The hotel has 44 floors and it is 154 metres high.

The structure is defined by exposed steel elements on the facade that also contain the bracing to ensure the building is horizontally stable. The interior is composed of a steel structure with a composite steel deck floor.

As there was hardly any prior experience of this type of buildings in Barcelona, especially on the seafront, innovative design systems and on-site load validation had to be used.

Las Arenas Retail and Leisure Centre

Sector: Building
Client: Richard Rogers and   Alonso-Balaguer
Years: 2002 – 2011
Description:

 

Refurbishment of the former Las Arenas bullring to transform it into a new retail and leisure centre in Barcelona.

Among other issues, the project included keeping and shoring the protected facade while the new five-floor basement was constructed, as well as the design of a multifunctional space in the roof, which is only supported by four tree-shaped columns.

The space is topped by a wooden dome that is 80 metres in diameter.

The planning of the construction process had to take the proximity of the metro lines into account.

Sector: Building
Client: Richard Meier & Partners
Years: 1988 – 1994

MNAC - National Palace of Montjuïc, Barcelona

Sector: Building
Client: Gae Aulenti, Enric Steegman and Josep Benedito
Years: 1989 – 2006
Description: Refurbishment and consolidation of the building constructed for the 1929 Barcelona International Exposition to house the National Art Museum of Catalonia.

Given the diverse structural types in the initial construction, a wide variety of construction methods had to be employed for the reinforcement works, including widening girders, lining vaults and the systematic creation of suspended floors supported by the original caisson foundation.

However, the most exceptional part of the project was the need for expansion joints in a building over 200 m long that did not have any, which is why it had cracks that were sometimes more than 10 cm wide. For that reason, walls up to 20 m high had to be cut from top to bottom using a continuous wire saw, and the dome above the great hall was cut into eight sections.

Olympic Basketball Arena, Badalona

Sector: Building
Client: Esteve Bonell and Francesc Rius
Years: 1990 – 1992
Description:

 

Design of the Olympic basketball arena for the 1992 Olympics in Barcelona.

One of its most important design features is the elliptical roof with spans of up to 120 metres. It comprises a main post-tensioned central girder with a variable depth (up to 15 metres) supporting the transverse beams designed as Fink trusses with spans between 40 and 80 metres.

The court and attached facilities are located below ground level; the platforms for the warm-up courts and other facilities are supported by concentric-depth beams spanning 18 metres.

The top floors stand out as the structural floors cantilever from the central core support with spans of up to 12 metres.

The facade structure in this top area is made of steel.

Foredeck Building, America’s Cup 2007, at the Port of Valencia

Sector: Building
Client: David Chipperfield and Fermín Vázquez and b720 Arquitectos
Years: 2005 – 2006
Description: The design of this emblematic building at the Port of Valencia is based on the concept of four floating structural floors supported only by four core areas giving rise to spans of 30 metres and cantilevers of up to 12 metres. The structural solution includes post-tensioned composite slabs with a depth of 1 m.

The design team had to adhere to a very short time frame, since they had only 14 months from the award of the tender contract to establish the structure on-site.

General improvement. Les Masies de Voltregà bypass. c-37 road

Sector: Transport
Client: GISA
Years: 2003 – 2004
Description:

 

The C-17 road (former N-152 road from Barcelona to Puigcerdà) is one of the most important corridors connecting the metropolitan area of Barcelona with the Pyrenees. The project started at the junction between the C-37 and C-17 roads in the municipality of Les Masies de Voltregà. From this point the C-37 road was doubled to the BV-4608. This dual carriageway section coincides with the Vic – Olot and Vic – Ripoll corridors to the west of the existing road. The fork for the C-17 and C-37 roads starts at 1+000 and the number of lanes increases from two to three in both traffic directions.

From the previous junction, the new bypass continues as a two-lane dual carriageway crossing the River Ter over a bridge that is 291.50 m long and 24 m wide, and which ensures enough depth for a flood return period of 500 years.

The section continues to connect with the Sant Hipòlit de Voltregà road with a junction formed by two roundabouts that are 40 m in diameter and a viaduct forming a flyover. Next, the dual carriageway crosses the Riera de Vinyoles with a 76.95-m long bridge. With a curve of 530 m radius, the bypass continues until it connects with the C-17 and BV-5225 roads and Torelló junction by means of a roundabout and two underpasses.

A-24 Highway: Lleida – Huesca. Section: Monzón Bypass.

Sector: Transport
Client: Ministry of Public Works and Transport
Years: 2002 – 2003
Description:

 

The Monzón bypass is a section of highway from Lleida to Huesca that is 12.06 km long. Its cross-section is two carriageways each with two lanes. Its horizontal and vertical alignment parameters classify it as an AV-100 with a circulation speed of 100 km/h.

The Monzón bypass is of special interest for diverting passing traffic from the N-240 road given the traffic congestion problems and hold-ups occurring at the Monzón crossing. The problem with the Monzón crossing on the N-240 road, where local traffic mixes with passing traffic, is aggravated by the fact that a Monzón street with traffic lights and the local roads A-1236 from Monzón to Fonz and A-1237 from Monzón to Almunia de San Juan all meet with the N-240 at this point.

Improvement of the East Sea Wall Phase 1

Sector: Transport
Client: Autoritat Portuària de Barcelona
Years: 2011
Description: Phase 1 consisted of the demolition of the existing pavement, footway and wall and the construction of a new superstructure with a clear width of 5.20 m.
