Enayam Port

Tamil Research Institute
RAPID TECHNO-ECONOMIC FEASIBILITY REPORT FOR
DEVELOPMENT OF COLACHEL PORT AT TAMILNADU
FINAL REPORT
Berth equipment such fenders, bollards, ladders or mooring rings have been considered. Both fenders and bollards
have been assumed to be located every15 m.
STS rails (A150) and fixtures (pads, clips, plates, bolts, etc) have been considered along the container berth as well.
Dredging and reclamation
This section includes the dredging costs to obtain the required drafts for the basin, the berth pocket and the approach
channel. It also includes the costs for land reclamation, which is assumed to be done through dredging from
surrounding areas of Phase 2 and 3 of the port. Finally, the ground improvement of reclaimed areas has been
included too.
Reclamation for port related industrial areas has been included but no ground improvement or pavement has been
considered. Instead of it, ground improvement costs are only estimated over the yard areas of the port.
A breakdown of quantities on dredging and reclamation is included in clause 9.5.
Rates for dredging include equipment mobilization, demobilization and service tax (14.42%).
Yards
Pavement design has been estimated in different areas. Three zones have been studied:
• Container yard-Stacking area:
80 mm thickness concrete block paving + 30 mm laying course material + 470 mm cement bound granular
mixture C8/10 + 450 mm aggregate sub-base + 900 mm capping layer
• Container yard-Operation area:
80 mm thickness concrete block paving + 30 mm laying course material + 560 mm cement bound granular
mixture C8/10 + 450 mm aggregate sub-base + 900 mm capping layer
• Multipurpose area:
240 mm concrete C32/40+ 150 mm aggregate sub-base + 900 mm capping layer
The design has been performed in accordance to “The Structural Design of Heavy Duty Pavements for Ports and Other
Industries” (NTERPAVE -4th Edition: 2007), based on British Standards and broadly used for this kind of ports.
ARMG concrete beams, rails (MRS 87A) and fixtures have been considered in container yard too.
Equipment
The quantities included in this section are the required so that the terminal is working at full capacity in 2020.
Buildings
A rough estimate of buildings has been made in this section. Four entities are included, depending on the type of
building.
• Administrative and operation buildings: Port administrative building, private operator administrative building,
port and yard operations buildings.
• Maintenance buildings: Cranes maintenance and others repair buildings,
• Utility Buildings: Fire station, electrical sub stations, fuel station, reefer shop and other utility buildings.
• Miscellaneous buildings: Canteen, quay workers restrooms, security booths, and others.
