The new Psychiatric Facility built adjacent to Vejle Hospital in Vejle, Denmark provides a psychiatric emergency room, a children’s and youth department and about 100 psychiatric beds.
The new facility was built on an embankment of approximately 20.000 m² on postglacial organic clay. The embankment was constructed as part of preparation of the building site. The filling height of approximately 4.5 m was carried out stepwise to prevent failure in the sub soil.

Crossrail C501 Liverpool Street Station
Crossrail is set to deliver a high frequency, high-capacity service to 37 stations linking Maidenhead and Heathrow in the west, to Shenfield and Abbey Wood in the east via 21 km of new twin-bore tunnels under central London. It will bring an additional 1.5 million people within 45 minutes commuting distance of London’s key business districts.
Advanced station works were carried out for the Moorgate shaft to provide ventilation and emergency access to the western end of the new Crossrail Liverpool Street station.
Work included the construction of a diaphragm wall and the removal of existing large diameter piles within the excavation.
In order to protect the Grade II listed buildings immediately adjacent to the shaft boundary at 8 Moorfields and 87 Moorgate, a steel frame was be installed within the buildings to prevent structural damage during construction of the shaft.

Al-Faw Grand Port
Staging Pier/Eastern Breakwater for Al-Faw Grand Port
Both Iraq and the broader northern Gulf region need a fully-equipped deep water sea port with sufficient capacity to handle rapidly growing volumes of international trade. The Iraqi government identified the existing port of the Al-Faw Peninsula, where the Shatt Al-Arab meets the Gulf, to be developed to meet this need.
The depth of the quays (-17.5 m) will allow the operation of the new generation of container ships. The special quays will be 7,000m long (about 20 berths). The specialist quays for moving dry bulk will be 3,500m long (about 12 berths).
A dredged channel 400m wide and 24km long will connect the new port to the deep water; dredged volumes will be approximately 60.000.000m3 for the navigation channel and 82.000.000m3 for the port basins, protected by rubble mound breakwaters approximately 15km long.
As part of the port development a rubble mound breakwater approximately 15km long was constructed.
