METROPOL PARASOLSeville, Spain (2005-2011)

Metropol Parasol, is a place of identification and to articulate Seville’s role as one of the world’s most fascinating cultural destinations. It is a redevelopment of Plaza de la Encarnacion, Seville, Spain as its role as a unique urban space within the dense fabric of the medieval inner city of Seville allows for a great variety of activities such as memory, leisure and commerce. Highly developed infrastructure helps to activate the square, making it an attractive destination for tourists and locals.

Realized as one of the largest and most innovative bonded timber-constructions with a polyurethane coating, the parasols grow out of the archaeological excavation site into a contemporary landmark, defining a unique relationship between the historical and the contemporary city. “Metropol Parasols” mix-used character initiates a dynamic development for culture and commerce in the heart of Seville and beyond.

The site area cover by this project was around 18,000 square meters with the building area of 5,000 square meters. This 4 levels of building with the height of 28.50 meters. The roof of Level 1 is the surface of the open-air public plaza, shaded by the wooden parasols above and designed for public events. Levels 2 and 3 are the two stages of the panoramic terraces (including a restaurant), offering one of the best views of the city centre.

Most of the surface and solid structure were built by using concrete, timber and steel (Principal for exterior are timber and granite while principal for interior material were using concrete, granite and steel). The project took around 1 year for planning and more than 6 years for construction with 90 million euro.

He won multiple awards and one of his iconic works which is the Metropol Parasol is located in Spain. His building is a wood-en structure located right in the centre of La Encarnacion square in the old parts of Seville, Spain.Inspired by illustration and approach of art abstract as for Metropol Parasol it’s inspired by art of medevial and archaeological aspect as the trees and old cathedral structures around the site which is also an ancient market which gives him inspiration of making a building that express and shows sustainability of the lifestyle and culture of the site.He wants to create an iconic building which is elevated but also creates a building with modern construction technology and unique materials like wood which is not widely used to building an en-tire building as structure and appearance.

THE ARCHITECT

JÜRGEN MAYER H.

Founded in 1996 in Berlin, Germa-ny, J. MAYER H Architects’ studio, focuses on works at the intersection of architecture, communication and new technology. Since he was a student, most of his works were into art abstract and portrait in the way of expression of relationship of the human body and nature.The founder and principal of this cross disciplinary studio. He studied at Stuttgart University, The Cooper Union and Princeton Universtiy. His work has been published and exhibited worldwide and is part of numerous collections includ-ing MoMA New York and SF MoMA. Na-tional and international awards include the Mies-van-der-Rohe-Award-Emerging-Ar-chitect-Special-Mention-2003 and Winner Holcim Award Bronze 2005. Jürgen Mayer H. has taught at Princeton University, Uni-versity of the Arts Berlin, Harvard Univer-sity, Kunsthochschule Berlin, the Architec-tural Association in London, the Columbia University, New York and at the University of Toronto, Canada.

SECTION B-B5

CONSTRUCTION METHODPhase 1: Concrete structure -The solid steel structure of the museum and marketplace and the steel/concrete structure for the high-level cafe are completed. -Two of the concrete cores that house lifts and four concrete plinths have been constructed.

Phase 2: Timber trunks

-Construction of the timber trunks starts with the base plates at the top of the concrete plinths. -The timber panels, which are up to 16m high, are then set up according to a sequence which ensures temporary stability at all times.

Phase 3: Main structure -The individual elements immediately above the trunks are prepared at the plaza level before they are hoisted into place at high level. -The fire protection is constructed at the lower half of the trunks.

CONSTRUCTION METHODPhase 4: Scaffolding up -Scaffolding is built to temporarily support the main timber structure outside the area of the trunks. -Work started at the rear of the site and two cranes were needed to attend to the simultaneous erection of scaffolding and timber.

Phase 5: Scaffolding down

-Scaffolding is taken down zone by zone, from the outside of the structure inward, with continuous control of the structure ensuring safety. -The overall plaza is repaved and all urban infrastructures finished.

Phase 6: Finishing touches -The entire scaffolding has been taken down, and the high-level walkway constructed on top of the timber structure. -All services, such as lightning protection, are installed within the timber structure.

CONSTRUCTION MATERIALSIndividual precast concrete

Bent metal piece

FFM’s Kerto-Q light timber beams with a polyurethane coating

Tie rod

Steel reinforced concrete base

-The coat of the Parasol is self-cleaning, and only needs repainting every 20 to 25 years. -The architects decided on FFM’s Kerto-Q light timber beams with a polyurethane coating, which is cheaper than metal but still durable.-The polyurethane coating protects the wood and allows it to breathe - a sort of natural air conditioning and the wood itself doesn’t give off hazardous fumes when it burns. -It is also sustainably planted, with a certificate PEFC (Programmed for the Endorsement of Forest Certification schemes), granted by the Finnish Forest Council of Certification.

-Unusually the parasols are a composite structure, with the tie rod, to carry the tension forces.-The main elements are penetrated by two tie rods at the point where those sections meet, and these parts aren’t visible from the outside.

-Metropol’s interweaving waffle-like wooden panels rise from concrete base reinforced with steel. -This is to support the wooden structure (surface structure) as a Solid Structure.

LOAD DISTRIBUTION- Metropol Parasol is designed from the concept of tree. The whole weight of the tree is supported by it’s from the small brunches to the bigger brunches, transfer to the trunk and finally to the root and discharges into the ground.

- Diagram 1 is the stress analysis of the panel, Red to green colour represents the stress from high to low.

- As the labels are connected with releases in the intersection points around the vertical axis, the internal forces from the bearing capacity of plates are almost always negligible.

- Normally, the stress design is reduced to the stress occurring within the plane of the timber sheet.

- The timber cross-sections in the branching points where the timber grid-shell is divided into a top and bottom part.

- Diagram 2 shows the weight/ stress flow.

- The platform of the sky cafe also supported by the triangular support system and also weight transfer to the centre as show in Diagram 3.

LOAD DISTRIBUTIONThe whole Wood Panels is a surface structure which supports the whole form and the weight of them is transfer into the centre by using tensile strength similar to a tree.

MODELLING PROCESS

SIZE OF DIFFERENT COMPPONNETNT

Refering to orthographic drawings of the actual building measurement of individual parts were rescaled to 1:200 for the size model and 1:200 for details construction part. There measurements were used for paper molding later.

SITE CONTEXT

In order to create site context similar to actual site we used also balsa wood with accurate scale and proportion

STUDY MODEL

Here is our study model which we were doing all of our discussion with it and during analysis and all of the stages of making our model it was helpful for us.

1211

Large amount of balsa wood were cut perfect-ly in a shape of real building’s construction elements like floor, wall, columns and even the smallest parts the we were connecting them all together same as actual building.

DETAILS

As all of the details were cut and measured as close as and as proper as the exact mea-surements of the section and elevations of the building , and this will make our building too much realistic.

MODELLING PROCESS

15

In the continue of progress we started to make different the same parts in the dif-ferent scales. for more details we made the smaller scale which is our biggest joint model , then we made the also another one that shows many of those joints to-gether and in next one we show the whole building, for making it more realistic we used silver paint for the joint model and for the iron wires that keeps the woods tied together we used some wires that makes our models more realistic.
