Safety interventions of a launching beam for the passage of typhoons.
The new connection between the island of Lantau in the Hong Kong archipelago and the artificial island of Check Lap Kok, on which the Hong Kong International Airport is based, is part of the development of the road infrastructure network that branches off to China to the north (Tuen Mun) and to the east (Macao), with works of impressive size that illustrate the ferment of Hong Kong and China.

Our intervention involved the safety of the assembly equipment of the prestressed reinforced concrete viaducts that connect Tuen Mun along an arm of the sea to the artificial island adjacent to the airport. The area of southern China where the Hong Kong archipelago is located is in fact subject to a long season of typhoons that reach winds above 250 km / h; the equipment in question, specifically the launching car that lays the prefabricated reinforced concrete blocks, had not been appropriately sized given the condition of exposure to the effects of a typhoon and for this reason the construction management of the work had blocked its activities with consequent shutdown of the construction site.

The project
Problem solving
To unblock the impasse created and avoid the heavy economic repercussions, the client requested the presence on site of one of our managers, called to assist in the re-inspection of the launching wagon in the exceptional scenario of the typhoon and to study the devices for putting safely on the batteries of the equipment. We have therefore produced the necessary documentation to illustrate the suitability of the equipment built and the project documentation necessary to build the temporary safety devices, allowing our client to quickly obtain authorization for the resumption of work by the validation body of the Hong Kong authorities.
We also provided assistance to the construction site during the production and installation phases of these devices, carrying out checks and modifications to the devices in real time due to the changing logistical needs of the construction site.
