Abstract

Die bou van die Hugenote-tonne1 tussen Paarl en Worcester op Nasionale Roete N1 is die grootste enkele projek wat die Nasionale Vervoerkommissie nog aangepak het. 'n Hele aantal kleiner, maar ewe interessante, kontrakte het dle hoofkontrak voorafgegaan om die terrein voor te berei. Dit sluit in die bou van 'n loodstonnel, die toepassing van grondbevriesing in die ontgrawingsproses van die sagte grondgedeelte van die hooftonnel en die bou van die indrukwekkende Hugosrivier-viaduk. In die hoofkontrak is baie suksesvoile gebruik gemaak van 'n stelsel van gekose onderaannemers vir die uitvoering van gespesiaiiseerde werk, waarvan die elektro-meganiese toerusting van die tonnel en sy beheersentrum die belangrikste was. Na suksesvolle onderhandelings met die aannemer is die oorspronklike kontrak uitgebrei om ook die ontgrawingswerk van die toekomstige dubbelbaantonnel intesluit.

The construction of the Huguenot Tunnel between Paarl and Worcester on National Route N1 is the largest single project yet undertaken by the National Transport Commission. A number of smaller, but equally interesting, contracts like the construction of a pilot tunnel, the use of ground freezing methods for excavation in saturated soft material and the building of the imposing Hugo's River Viaduct prepared the scene for the main tunnel contract. In the main contract a system of selected subcontracts was very successfully applied for specialized work, with the electro-mechanical equipping of the tunnel and its control centre being the most important. As a result of successful negotiations with the main contractor, the original agreement was extended to include the excavation of the future double carriageway tunnel.
