| Notes: A vital link in the Thiess / Santos / GLNG gas transmission pipeline from the gasfields near Roma to the liquefaction plant on Curtis Island near Gladstone, this 4.3 km long x 3.4m internal diameter underground tunnel was constructed with high performance precast segmental lining. 54 No. high precision moulds were cast twice a day, 6 days a week using advanced concrete technology and curing methods to meet the tight delivery schedule and ensure the tunnel boring machine could run around the clock uninterrupted. This is the third segmental tunnel lining project undertaken by the Precast Group and was a great success for the company and our clients. |
