In January 1852, it became clear that the government authorities would not sanction the purchase of sufficient land nor the necessary water frontage, despite demonstrations from Turnbull that the terminus would continue to expand. In May 1852, the detailed station plans were the major work of Turnbull and his team of engineers. In October, four tenders for building the station received from 190,000 to 274,526 INR against an estimate of 250,000 INR.
