PORT HARCOURT UNIVERSITY

CONSTRUCTION PROJECT

Nigeria, 2011-2012

The project consists on the design of a

new university campus in the city

northwest, close to the Port Harcourt

international airport. The university is part

of the Urban Development Plan for the

city, whose promoter is the State

Government of Rivers State, Nigeria.

Esteyco, as a collaborator of the Angel

Asenjo studio, designed the construction

projects of structures of singular

buildings such as the library, the church,

the multi-use hall, among others, and a

six level accommodation building.

The construction plot of ≈170 ha where

the campus will be located is already

under the first phase of the construction

process, and according to the “Master

Plan” the rest of the phases will be

developed afterwards.

The construction area of ≈700,000m2 , is

divided in 87 buildings of several

different sizes and shapes. Different

typologies are developed, being the

predominant theme the reinforced

concrete beams and post tensioned

flagstones, sometimes combined with

metal profile modulus, creating

combined framings (concrete and steel).

The Rector and Conference buildings

are designed with more complex and

expensive enclosures, with metal sheets

of titanium or galvanized steel.

DSA-3 DEEP SPACE ANTENNA IN MALARGUE

CONSTRUCTION PROJECT, SITE WORKS MANAGEMENT

PROJECT MANAGEMENT

Mendoza, Argentina, 2010-2011

The DS3 Deep Space Antenna design

and construction was comissioned by

the European Space Agency, ESA, near

Malargüe, in the province of Mendoza,

Argentina. With the existing facilities in

New Norcia (Australia) and Cebreros

(Ávila) the new facility will complete the

system which receives signals sent by

satellites that explore Mars, Venus and

other planets of our Solar System.

The sensitivity of the electronic

equipment conceived by Canadian

engineering firm SED-Systems stricltly

limited the displacements of the pedestal

for the parabolic antenna, 35 m in

diameter, that was built in Germany by

Vertex Antennentechnik. The antenna

and pedestal were made to withstand

winds of up to 80 km/h without

exceeding rotations of 1/82,500 radians,

which is the equivalent to movements at

the head of the pedestal of 0.075 mm.

The structure is dimensioned to

withstand winds of up to 180 km/h and

seismic accelerations of 0.4g.

WORKS MANAGEMENT

Barcelona 2009-2011

•Birdseye view of the Market.

•Extension proposal cross-section.

•Floor-plan of the existing structure.

The Sant Antoni Market is located in the

heart of Barcelona, occupying one

complete city block of Cerda’s Ensanche

situated between the Paral·lel and the

Raval neighborhood. The current Market

building is shaped like a cross whose

limbs are arranged in a north-south and

east-west direction occupying the

block’s diagonals.

The structure of the limbs, which are 20

meters wide, is made up of two lines of

cast iron pillars, separated approximately

5 m, which make up the framework of

the lateral façades. Traditional riveted

Polonceau-type metal trusses are placed

transversally and underpinned by the

pillars. On these beams purlins with a 5

meters span and a lattice of wooden

beams are arranged supporting a fiber-

cement roof.

Four underground floors are built in the

remodeling project, the first is destined

to commercial and the rest to different

uses: parking, merchandise entrance

and storage space.

Project presented to tender for the Camp

Now Stadium enlargement, developed in

collaboration with Martinez Lapeña &

Elias Torres architectural studio.

In order to achieve the urban

transformation that has to be developed

as well as to generate the required

resources, the enlargement is not seen

as an end but as the means to achieve

the former objectives.

The stadium design creates a balance

between both public and urban spaces.

Conceptually, the project consists of an

underground pedestal where the

functional spaces that serve as

foundation for the new stands and metal

ribs that cover the stadium. The metal

ribs will function as skin, cover and

facade for the stadium

An atrium formed by 80 inclined columns

is generated by the “umbraculum”

structure with the rib succession giving

an angle shape.

The deconstruction and construction

processes of the third terrace area and

its cover was designed foreseen the

continuity of the football competition

while the construction takes place.

LIFTS TOWERS AND WALKWAYS IN AMETZOLA

CONSTRUCTION PROJECT AND TECHNICAL ASSISTANCE TO THE SITE WORKS

MANAGEMENT

Bilbao. 2006-2007

The solution proposed to solve the

continuity of the urban fabric consists of

creating a big park on the slope which

will be used as support of all the

communication elements among the

different points of the area, enabling the

pedestrian mobility by means of the

construction of roads, walkways, ramps

and stairs. The proposal would allow

accessibility among different streets

without architectural barriers and

combine the solution with a

complementary access to the three

levels of the underground car park

located under the Avenida del

Ferrocarril.

This project develops the connexion

solution between Padura Street and

Ferrocarril Avenue through the

construction of a vertical communication

structure compossed of two lifts for

independent use of the car park and

pedestrians and connected at Padura

Street through a pedestrian walkway of

three metres wide. The structure is

located on the space reserved to a car

park emergency exit, leaning on the

concrete walls which forms the shaft. It

was necessary to make both lifts

independent by means of the

construction of two concrete towers,

separated by the distance of the

footbridge, which will also be the support

for it. The low tower, of 14 m high,

includes the connexion lift between

Padura and the car park. The highest

one, of 22 m, stands out in Padura as

the unique element of connection

between the highest part of Irala and

Ametzola area.

Both towers, the walkway and the car

park exit building, form a single element

made of concrete and coloured glass,

located at a strategic spot at the end of

the avenue and with the future Irala park

as backdrop.

• Elevation of lift towers.

• Foreshortened perspective of the built

towers.

• Night view highlighted thanks to the inner

lighting.

Both towers, the footbridge and the exit

structure framework of the car park are a

unique element made of concrete and

coloured glass, strategically located at

the end of the avenue, and with the

future Irala park as a backdrop.

Located in the historic downtown of

Alcalá next to the future buildings of the

Courthouse and the Tourism Parador.

The parking garage is characterized by

its spatial diaphanous quality, enabled

by the choice of a large-span structure

typology that distinguish the inside

space, turning it into a large area, lit with

natural light, and that enable optimizing

functionality. The garage consists of two

floors below ground level, with a surface

area of 66.50 by 63.40 m and a 2.60 m

clearance height between floors. It

provides over 300 2.60x5.00 m parking

spaces for rotational use. A one-way

road design allows the arrangement of

the traffic, providing an adequate

functionality and safety. Circular

skylights, each 7.80 m, are located

along the axis of the roads of level -1

providing natural light to the inside. This

same diagram is repeated in level -2,

aided by artificial lighting.

The access/exit of vehicles takes place

through a wide two-way ramp

perpendicular to Santo Tomás de

Aquino Street. The ramp is open to the

outside on both floors, providing natural

lighting and ventilation to the inside of

the parking, and allowing a visual

relation with the exterior. The ramp,

converted in to a one-way, continues to

level -2. The exit takes place through a

wide circular ramp. The position of the

ramps has been designed in a way that

allows the greatest degree of functional

independence between both floors,

avoiding unnecessary traffic. This

improves and facilitates the use of the

parking. Three pedestrian accesses,

located in unique spots of the square

and the parking garage, have been

designed. Skylights are incorporated,

thus allowing oneself to find one’s way

easily from any point in the inside,

thanks to the abundance of natural light.

LA PALOMA SQUARE UNDERGROUND PARKING

GARAGE

CONSTRUCTION PROJECT AND SITE WORKS MANAGEMENT

Alcalá de Henares, Madrid. 2006-2007

The underground parking in the

Eucaliptus square, in the Torre Baró

neighborhood, is located in a very

important block within the neighborhood,

since we can find nearby a health centre,

a library, a metro station and a regional

train station.

The narrowness of the plot provides a

great complexity to the building. The

parking is going to be carried out at the

same time than the adjacent one,

although they both have an autonomous

operation.

Both share, nevertheless, the road

accesses and the double direction only

ramp. That optimizes the use in floors of

the limited plot.

The car park consists of three floors in

total. It has 171 standard parking

spaces, five for disabled and ten for

motorcycles.

UNDERGROUND CAR PARK IN LOS EUCALIPTOS

SQUARE, TORRE BARÓ NEIGHBOURHOOD

CONSTRUCTION PROJECT

Barcelona. 2008-2010

The parking is strategically located in the

cultural activity center of the city of

Bilbao, next to the Guggenheim and the

Arts museums, Deusto University and its

new library, and the new auditorium of

the Basque Country University (UPV).

Located as well next to the tower of

Iberdrola, which will be inaugurated in

2011, and will be the biggest building of

Euskadi, mainly full of offices.

Geometrically speaking, the parking has

a semicircular plant under the city

square with an extended “arm” heading

the Ria under the new street Ramon

Rubial. There are 4 levels of 2.6 m of free

height between forgings. It contains

almost 800 parking places, of 2.5x5 m,

of which 400 are accessible for any user

(levels -1 and -2) and the rest for

residents of surrounding neighborhood

areas(levels -3 and -4). A design of vials

with just one direction, of 5.5m width,

allows a fluent and well-arranged

circulation of vehicles, with an adequate

functionality and security.

The accesses for vehicles will be

performed through the R. Rubial street at

the levels n-1 (entrance) and n-2 and a

third gate is foreseen (n-3) for residents

under the Deusto Bridge.

Due to the location in singular points,

Mazarredo, Deusto bridge and R. Rubial,

all three pedestrian accesses are

adapted to the final shape of the square

that is to be constructed, integrating in

the design of it the ventilation exits of the

parking through sculpture elements.

The construction of the structure has

been done along side with the

urbanization projects of the square itself,

the R. Rubial street and the surrounding

buildings.
