PUERTO QUETZAL, GUATEMALA - SUPPLY COMPLETE

Supply has just finished to the berth scour protection project in the central American pacific-facing port. A total of 19,100 m2 of scour protection mattress was engineered and delivered to site over an 11-month period.

The deck superstructure was completed fast and resulted in the scour protection works having to be executed underneath an already constructed deck with limited access. The fabric mattress panels were supplied in lengths of 55m, which zip together to form sealed ball & socket joints once pump-filled with concrete.

HAITI JETTY RECONSTRUCTION – MATTRESS INSTALLATION COMPLETE

11 months since installation of the first mattress panel, GLF USA have completed installation of the final module of scour protection at the main container terminal (400m lg) and RoRo landing (35m) in Port-au Prince, Haiti.

The scour protection was designed with a high permeability mattress in the tidal zone, and an increased thickness mattress in areas vulnerable to propeller and thrust action underwater. Installation of the mattress was undertaken with assistance from local divers and completed in parallel to the deck construction.

The piling and beams for the superstructure were constructed on area of temporary fill material to remove the need for costly marine works. The fill material then has to be excavated out to form the slope beneath the structure. This is one of a number of recent ports that have adopted this ‘Land-Infill’ construction method.

PUERTO QUETZAL, GUATEMALA SCOUR PROTECTION

Supply has commenced to newly constructed piled jetty at Puerto Quetzal, Guatemala which requires berth scour protection to combat against vessel scour action to the slope and wave zone beneath the jetty. The 350m long berth is to accommodate Panamax type vessels with drafts up to 15.0 m and installed powers in excess of 70,000 kW.

Constant thickness (CT150) mattress is being used for the extent of the slope which is subject to propeller action and bow thrusters during berth and unberthing. The upper section, exposed to wave action, is an open-hole mattress (OH220) for increased permeability to allow for effective wave rundown. A rock falling edge apron protects the mattress toe and sides from underscour.

COMMUNITY PROJECT – CAMBODIA

Proserve are proud to have been involved with a community build project in South East Asia. The Bomnong L'Or project is located in the chaotic centre of the port city of Sihanoukville, Cambodia.

The architects Orkidstudio along with StructureMode used the method of casting concrete in lightweight fabric molds, fabricated using single layer fabric donated by Proserve. They teamed up with a group of Khmer women to rebuild the community centre at the city’s urban heart. For over 10 years, the centre has worked to deliver further education to local children and adults, as well as functioning as a community meeting and work space.

The new building contains all areas of learning and teaching on a higher floor, leaving a series of outdoor spaces for play and interaction. This typology mimics the traditional local houses on stilts, but replaces wood with fabric cast reinforced concrete. Timber cannot be sustainably sourced locally due to uncontrolled deforestation.

Adopting a completely passive climate strategy, the building seeks to present an example of affordable design and quality, combining traditional and modern techniques and seeking to establish a new type of Cambodian construction.

Venice Barrage:
FABRICATION OF GROUT BAG SYSTEM FOR FLOOD DEFENCE FOUNDATIONS

Venice is to be protected from its present flooding problems by the MOSE barrage project. The concrete caissons are founded using a grout bag foundation system by Proserve to Malamocco and San Nicolo inlets.

The grout bag system is being pre-fixed to the bottom of caissons. The caissons weighing some 200,000t are to be floated into position and immersed using control barges. The caissons will be temporarily supported and levelled on pin jacks. A protective cover to the grout bags will be released by diver and the grout bags are then to be automatically grouted using pre-fixed grout hoses and a grout level sensor. This overcomes the tidal currents in the inlet as divers can only operate in slack water periods. The system provides a complete layer of cement grout to support the caissons onto a compacted stone layer and piled ground improvement. It also provides reliable grouting compartments, prevents grout wash out and allows control of grout uplift pressures.

Caisson immersion is due to commence in 2013 with the barrage expected to be operable for 2015.

COMPLETION OF SHELL JETTY SCOUR PROTECTION

The existing Shell Jetty was deepened for larger vessels and the existing revetment slopes required protection from bow thruster erosion. A 150mm thick cast insitu concrete mattress system was designed with crack and movement control joints at 2.2m and 3m centres to accommodate settlement. An FP225 porous filter point mattress was used in the tidal range with a geotextile under layer pre-sewn to the mattresses. Lower slopes subject to bow thrusters wash were protected by CT150 mattress. Toe trenches were provided to mattress edges to protect against underscour. The installation of the mattress was carried out by Kaymac Marine.
