17. Road tunnels
In the last five years, Geoconsult has designed above ten road tunnels for highways, it means,
above 25 km excavation. Besides, we have participated as Supervision in important
infrastructure works such as bypass highways in cities like Bilbao, Madrid, etc
SOUTH METROPOLITAN BYPASS IN BILBAO:
(Pais Vasco. SPAIN)
This infrastructure runs a bypass beltway around
Bilbao city. For this, it was designed seven tunnels
with a big section ((Argalario, Mesperuza, Santa
Águeda, Arraiz, Larraskitu, Arnotegi and
Seberetxe), above 20 km excavated.
Some of our pioneer designed works are known
worldwide such as the construction of a huge
Big chamber in Arraiz tunnel chamber in Arraiz tunnel, 28 m wide and 100 m
long.
Larraskitu and Arnotegi tunnels portal
PEINADOR TUNNEL
(Vigo. SPAIN)
Double tunnel for highway that runs 20 m under
Peinador Airport. The tunnel has been designed to
be built without interrupting the landing and takeoff
operations.

MAMES
(Bilbao. SPAIN)
We have designed the exploitation
installations (electrification, ventilation,
lighting, safety, signalling, etc) in five
artificial tunnels and tunnel in mine for the
redesigning of the access to Bilbao
through San Mamés.
TUNNELS EQUIPMENT ADEQUACY

ASTURIAS
(Asturias. SPAIN)
The project redesigns the road tunnel
installations for its adequacy to the
minimum safety requirements. It includes
new designs of connection galleries to
access to emergency vehicles, CRT,
ventilation, lighting, protection against
fires, CCTV, safety, etc
INSTALLATIONS ADEQUACY FOR THE
SOMOSIERRA TUNNEL
The project adecuates the installations and
the existing equipment
20. Inspection and tunnel
rehabilitation projects
Geoconsult has carried out the biggest geotechnical surveys campaigns developed in Spain in
the lineal infrastructure works range.

REHABILITATION PROJECT.
LINES 1 AND 2. METRO DE
MADRID.
(Madrid. SPAIN)
Inspection to verify the structural
and functional status of the oldest
lines in Metro de Madrid (Lines 1
and 2).
With the data obtained by the
inspection, it was carried out a
project of structural support and
tunnels improvements
INSPECTION AND TUNNEL
REHABILITATION PROJECTS
FOR BASQUE RAILWAY
NETWORK IN GUIPUZCOA
(Guipúzcoa. SPAIN)
The project consists of the
inspection and drawing-up of
tunnels rehabilitation projects for
Basque Railway network.
To carry out this work, it was
used modern inspection
techniques with our own
equipments (GPR, Impact-Echo,
termography, etc.)
21. Mining
Geoconsult designs projects in huge underground mining exploitations
“A FRAGUIÑA” MINING EXPLOITATION
CHAMBER
(Orense. SPAIN)
In O Barco de Valdeorras (Orense), it has been
designed several underground chambers to
exploit shales.
Their dimensions are enormous for this type of
material: 60 m high x 30 m wide x 120 m long.
“APARIO” CHAMBER FOR CALCAREOUS
AGGREGATES EXPLOITATION
(Vizcaya. SPAIN)
In Lemona, it was developed the project Apario
Chamber. It is an underground exploitation for
calcareous aggregate. It uses the sublevels
method.
MINING PONDS MONITORING. “LAS
CRUCES” COPPER MINE
(Sevilla. SPAIN)
Monitoring by inclinometers, piezometers and
surveying.
22. Geotechnical surveys for linear
infraestructure
Geoconsult has carried out the greatest geotechnical surveys campaigns developed in Spain into
linear infrastructure works range.
GEOTECHNICAL SURVEY IN
PAJARES BYPASS
(Asturias - León. SPAIN)
Geotechnical survey of a high speed
railway section, 45 km long, including
Pajares tunnel (25 km). It was drilled
more than 20 km.
GEOTECHNICAL SURVEY OF THE
NEW RAILWAY ACCESS TO BASQUE
COUNTRY (Y-VASCA
(Vizcaya - Guipúzcoa. SPAIN)
Survey referred to layout mountain
section belonging to the new basque
network of high speed railway, 32 km
long, It was carried out more than 250
drillings, 10 km long
