Contracts 905 to 909 were previously referred to as the contracts for the MRT Downtown Extension. There has since been a change. All contracts concerning the MRT Downtown Extension are now referred to as the MRT Downtown LINE PHASE 1. This is reminicent of the former MRT Marina Line (which has since become Phase 1 of the MRT Circle Line). So speculation that the MRT Downtown Extension was part of the Circle Line is indeed proving to be pure speculation as its now part of its own line. Though not officially announced, this change in name when awarding contracts does prove that LTA has since firmed up its plans for the DTE, now DTL.Tender Reference (Contract No.)

Pre-Qualification Notice For Proposed Downtown Line Phase 1 (DTL) Rapid Transit System For Design And Build Civil Contract 905
INTRODUCTION The pre-qualification for the Downtown Line Phase 1 (DTL) for Design & Build Civil Contract 905 was advertised in the Hong Kong's South China Morning Post and GeBIZ on the 13 March 2006 and the names of the successful Applicants were released on 07 July 2006. The entire route length for DTL is approximately 3.4 km and consists of 4 new stations, Bayfront, Landmark, Cross Street and Chinatown stations. The proposed DTL will be packaged into 5 civil contracts 905, 906, 907, 908 and 909.
PREQUALIFICATION OF CONTRACT 905 This PQ is for Contract 905 which consists of 2 pairs of stacked bored tunnels across Marina Bay to CCL Promenade station. It involves the design and construction of mainly bored tunnels and a short stretch of cut and cover tunnels. A pair of stacked mined tunnels undercrossing the existing CCL tunnel is also included. The tunnel route length for Contract 905 is approximately 0.75km. Due to a change in the design scheme of Contract 905 from cut and cover to mainly bored tunnelling method, interested Civil Engineering contractors with proven expertise and experience in design and construction of bored tunnel works for Rail Transit System tunnels structures are invited to apply for this PQ.
On a side note, another fact to ponder over is that
1. Earlier contracts have asked for contractors to be prepared for constructing a shell box for Marina Bay Station Interchange
2. Tunnels fron Bayfront to Promenade are stacked twin tunnels = 4 tunnels
3. Overrun tunnels from Bayfront towards Marina Bay Station
So it does APPEAR that there will be tracks leading from Marina Bay Station to Bayfront and on to Promenade. And this could be the Circle Line Stage 6 we are thinking about. After all, what other line seems conveniently placed to connect to Marina Bay Station, and continue on with this possible Marina Bay-Bayfront-Promenade mini line?
LTA is one confusing authority.
