The deck to the section that will carry the Gautrain lines across Nelson Mandela Boulevard is well advanced and parapet erection is in progress. Pier and trestle beam construction is finished on the remaining sections of this “Y-shaped” structure that crosses above the existing Metrorail tracks.
Between Gautrain’s Pretoria and Hatfield stations, a number of road bridges crossing the existing Metrorail railway have been lengthened, to accommodate the new tracks which will run parallel. These include bridges at Ridge Road, Grosvenor Road, Cilliers Street, Bourke Street, Walker Street, Walton Jameson Avenue and Lynnwood Road. Finishing work continues on some of these. Extensive lateral support work in the cuttings, together with the earthworks and construction of retaining structures necessary to widen the existing embankments, are in hand.
HATFIELD STATION
At Hatfield, lateral support and excavation of the southern embankment is complete, and construction of the station itself is in progress. The concourse slab extending over both the existing Metrorail tracks and the future Gautrain lines has been completed. Preparations are in hand for platform construction below the concourse level, and erection of structural steelwork for the concourse building to be located on top of this slab is in progress. All eight levels of the parkade structure have been cast, precast parapet erection is well advanced and the adjacent lift shaft is approaching completion. M&E works within the parkade structure are in progress. At the Grosvenor Street bridge, the final deck span has been cast. Construction of management facilities within the bus terminus area is in hand.
