The Astm International Group (formerly American Society for Testing and Materials) has been awarded the contract for the renovation of some parts of the "John Fitzgerald Kennedy" international airport in New-York. The works will be carried out through the US subsidiary Halmar International, which deals with the construction of civil infrastructure, together with the engineering company Skanska. The project is worth 1.24 billion dollars.

The Port Authority of New York and New Jersey (Panynj), which manages the transport infrastructures of the two states, has awarded the joint venture (70% Skanska, 30% Halmar), the reconstruction of the viability of the Central Terminal area of the "John Fitzgerald Kennedy", as well as the construction of a Ground Transportation Center with a new parking lot and the upgrading of utilities, with the aim of increasing passenger services.

Astm Group's recent projects, through Halmar, include: the recent completion of the Long Island Rail Road expansion, grossing 1.83 billion dollars to build the third track; as well as the 264 million dollars design and construction of the Potomac Yard Metro Station for the Washington Metropolitan Area Transit Authority.
