PROJECTS

GEG - ENGINEERING STRUCTURES FOR LIFE

The expansion of the South Container Terminal at the Port of Leixões was a vital measure to increase the importance and dynamics of an infrastructure which has a great impact on the whole north area of the Iberian Peninsula. This part of the port occupies a 16 ha area and this specific project demanded the duplication of the area for containers storage and the design of a new extension for the existent railway, 500 meters in double track, in order to make it reach a more external end of the new containers storage area. GEG developed the study for the Port of Leixões’s South Container Terminal enlargement, including the design of the new railway and the project management. With this work, the south terminal acquired a capacity for 10.000 containers, which represents an annual capacity to deal with 226.000 containers.

APDL - IC1 motorway viaduct over Port of Leixões

Widening and Rehabilitation The IC1-A28 motorway viaduct over the River Leça and the Port of Leixões was built between 1956 and 1961, and is composed of two 405 meters long separated viaducts spread over 15 spans. The viaducts are constituted by a concrete slab supported on prestressed concrete girders and the foundations are on precast reinforced concrete piles. The enlargement and rehabilitation of this viaduct sought to solve the problems caused by an intense traffic flow, not just on the IC1 motorway but also the one generated by the Port of Leixões, and some serviceable problems. With this purpose, GEG developed in 1998 the traffic study and the design of the enlargement of the viaduct and its accesses, from 2x3 to 2x4 lanes, plus walkways, and developed the viaduct rehabilitation design, which included new expansion joints, bearing replacement and concrete rehabilitation. The enlargement structural solution comprised a reinforced concrete slab, which rests in longitudinal metal girders, supported by steel frames located in the alignment of the existing reinforced concrete frames.

Engineering solutions to solve collision damages In 2006 a vehicle collided with a steel beam causing the warpage in its entire length and breaking the connection between the bracing struts and the inferior beam. GEG was responsible for the inspection of the structural damage and defined a temporary structure and a new beam to replace the damaged one. In 2010 another accident occurred with the collision of a vehicle on the steel structure. GEG made the inspection analysis to the damage area and defined an engineering solution which consisted on the implementation of corrective and rehabilitation measures on the damaged structure.

The first bascule bridge of the Port of Leixões opened in 1959. It was a steel bascule bridge, 8 meters wide and with a 58.56 m clear span. In 1990 GEG developed the rehabilitation design of this remarkable bridge that maintained its function until 2007, when it was replaced by a new bascule bridge with a bigger span (94 meters) which increased substantially the channel capacity and enabled the access of bigger vessels. The rehabilitation design developed by GEG included the beam’s reinforcement, the structural joints elimination, the concrete rehabilitation and the access viaducts enlargement. GEG was also responsible for the structural inspection and design.

PROJECTS

GEG - ENGINEERING STRUCTURES FOR LIFE

This project concerned terrestrial accesses to a logistics platform which comprised three new zones, occupying a total area of 86 ha, and is part of the expansion project of the Port of Leixões. The accesses comprised in a new railway branch line with a total extension of 1.820 meters and a new roadway approximately 1.200 meters long. For the first 1.100 meters of the railway it is a single track, and for the remaining ones a double track. The roadway was set to have 2 lanes, 15.6 meters wide, considering the large paved side of the road, which may be adapted as another lane in the future, depending on the flux of traffic. Two interchanges were foreseen for the roadway, one of them with VILPL, the direct roadway link to the Port of Leixões. The adopted geometry for these accesses implied 2 roadway viaducts, 3 railway viaducts and 1 roadway underpass. For the roadway viaducts, with maximum spans up to 25 meters, two possible solutions were then studied and presented, considering either just using cast in place concrete or by integrating precast elements. The railway viaducts consisted in simple solutions, to the exception of the viaduct over River Leça, which amounted to a total extension of 310 meters, divided into 11 spans. GEG developed the feasibility studies and conceptual design for these railway and roadway accesses, including the geological and geotechnical studies, the road geometry definition, the structural and railway viaducts.

Following the feasibility studies for road and rail accesses to the new logistics platform, the execution design was developed for the road connection between the exclusive accesses to the Port of Leixões (VILPL) with the port’s expansion zones – Pólo Gonçalves. The roadway geometry suffered changes in relation to previous project phases, namely the suppression of an interchange by the inclusion of a roundabout. The roadway included a bridge that develops itself in a curve, being consequently transversely inclined. It is 18.10 meters wide and approximately 60 meters long, divided into three spans, the central one with a 33 meters span. The defined structural solution for the deck consisted in a cast in place solution with pre-stressed reinforced concrete beams. GEG developed the detailed design of all the engineering disciplines, including the road layout and earthworks, drainage and pavement design, signalling, foundations and structural design, and the communication infrastructures.

Within the whole framework of the project for restructuring the road network of the Port of LeixĂľes, new entrance gates for custom control at the south area of the port were also designed. Along the functional issues to be considered on the design of a gate structure, the client required that the structure should stand out against the whole port environment. Thus a steel structure was designed with that purpose while enabling, at the same time, a faster assembly and construction time. The structure is constituted by a curved roof supported by four W shape steel frames, joined on the top by the main beams. The columns are released on their base with the aim of annulling the bending stress. The structure comprised also a truck inspection gallery, located 5 meters above ground. GEG developed the structural conceptual and detailed design.

In the context of the project for the expansion and rehabilitation of the Marina of Leixþes and its surroundings, GEG developed the conceptual design and detailed design of a new quay bridge, including the geological and geotechnical studies for the foundation, the structural design, the coordination of architecture and engineering design. GEG also performed on-site technical support. This quay bridge would be used to support an international sailing event on 2007 but would also become a permanent structure, aiming thus a long life cycle and reduced maintenance requirements. With that purpose it was chosen a fixed bridge / pier solution, which establishes continuity between the existing quay, with access to the marina, at the water level, through a floating pontoons dock, and a linking ramp. The quay bridge’s deck is 10 meters wide and 60 meters long. The deck uses a composite solution, with concrete slab, mostly pre-cast, supported on steel profiles.

APDL - Slope stabilization of the roadway access to the Port

Due to the implementation of more tollbooths in the main toll entrance of the Port of LeixĂľes and the construction of a new lane, for access to the Silos, there was a need to stabilise the adjacent excavation slope along an entire length of 585 meters. The Port administration decided not to re-excavate the existent slope and so in order to reduce geotechnical risk solutions for slope stabilization were designed, including steel wire mesh associated with rock nails. In sections with enough available space and where the slope presented deteriorated rock a slope toe wall was defined. Rock fall was a potential risk and so retention ditches were planned along the top of the wall. GEG developed the geological and geotechnical studies, the roadway alignment definition, and the slope stabilization design.

The scope of work was concerned to the future salt water pumping station which is included in the Hamriyah power plant, the largest in the Emirate, and compasses the construction of intake and outfall structures and the pumping station. The consultancy services provided by GEG were related with the Design and Construction Supervision contract regarding this project, commissioned by the Sharjah Electricity and Water Authority (SEWA) to Sogreah Gulf. The pumping station consists of a single storey reinforced concrete structure and the bottom of the pumping station is located about 13 m below the finished grade level. The ground stratigraphy at the proposed pumping station location consists of sand fill underlain by native sand. A silt layer was noted within the native sand at some parts of the project site. Generally, groundwater was encountered at depths ranging from 1.6 to 2.8 m below the current ground surface. As a consequence of high growth in demand and environmental considerations there is a great need to expand water production facilities by desalination while maintaining or reducing abstraction from ground water and partially desalination by use of brackish water RO systems. This project is expected to raise the total generation capacity of Hamriyah Power Station on 2,850 MW and to provide, in 2012, a total desalination capacity of 140 million gallons of drinking water per day.

The right bank of the River Douro, near Arrรกbida Bridge was the location of Massarelos bridge pier. The client Helitours wanted to rehabilitate and expand this space, with the purpose of preparing it to become a heliport platform. GEG was responsible for the development of the structural inspection, the structural design of the new structure and the rehabilitation design of the pre-existent bridge-pier. The visual analysis of the pre-existent Massarelos bridge pier revealed a noticeable degradation. The scope of this project included the data analysis of the pre-existing

GEG - ENGINEERING STRUCTURES FOR LIFE

This project was requested by the Municipal Water Authority as a result of erosion phenomena occurring during the winter of 2014 with a consequent retreat of the dune system, putting the presence of some infrastructure and buildings at risk. There are many causes for the degradation of the dunes, ranging from the simple trampling to the opening of roads and paths, the off-road vehicles circulation and the sand extraction. However, the severity of the autumn and winter months of 2013 and 2014 contributed significantly to an abnormal development of these damages. The implementation of coastal protection reinforcement measures is part of a broader range of counter-erosion and coastal defence measures which are to be
