1 THE IMMERSED TUNNELS MAIN BENEFITS AND INNOVATION BY. WAWAN SETIAWAN

2 GENERAL

3 GENERAL

4 THE CHARACTERISTIC OF IMMERSED TUNNELS Bila di bandingkan dengan jembatan, bore tunnels konstruksi immersed tunnels memiliki potensi lebih murah, lebih cepat dan lebih aman.

5 Cost effective Hydraulic Impact Decrease Visual and Air Impact Decrease Suitable for various and relatively poor soil conditions Parallel construction processes Relatively low and manageable risk profile Capable of dealing with (severe) seismic events 80-90% of all design and construction works can be done by local companies (limited input from international specialists) THE ADVANTAGES

6 Environmental impact of dredging Contaminated soils But also opportunities ? Land reclamations Construction impact on shipping Limited and manageable impact In practice often an issue that can be addressed properly by good communication DISADVANTAGES / PREJUDICES ?

7 Rectangular, circular etc Cost effective wide tunnels PRACTICALLY EVERY SHAPES

8 Air memberi manfaat kemudahan pelaksanaan PRACTICALLY EVERY WATERWAY

9 Soil Investigation Design Feasibility Studies Dredging Construction Immersion Safety Testing Running Operation IMMERSED TUNNELS SUPPLY CHAIN

10 KEY STAKEHOLDERS

11 PARTNERSHIPS POTENTIAL

12 PELUANG PTPP DI PROYEK IMMERSED TUNNEL IMMERSED TUNNEL DAN REKLAMASI MEMBUKA PELUANG PARTNERSHIP DENGAN PERUSAHAAN BELANDA

13 Type Partnerships Yang bisa dikembangkan 1.Collaborative Strategic Alliance : Short term, partnership untuk proyek-proyek tunggal, bermanfaat untuk membangun kompetitive advantage 2.Cooperative Strategic Alliance : Long term, pembentukan alliance body, bermanfaat untuk mutual learning dan transfer of knowledge PELUANG PTPP DI PROYEK IMMERSED TUNNEL

17 OTHER CASE Menurut Professor Indrasurya B. Mochtar (ITS) bahwa Immersed tunnels lebih cocok dikembangkan bila di banding dengan jembatan karena tidak akan mengganggu penerbangan. Rencana pengembangan tol bandara oleh pemda BALI
