1. INTRODUCTION
1.1 Background
Part 1 - Repair to Service Berth no. 4
Service Berth No. 4 was constructed as part of seven service berths in 2000-2001. Four of these berths have
developed cracking of mass concrete blocks in the quay wall structure attributed to Delayed Ettringite
Formation (DEF). Three of the most severely affected berths were replaced in 2010-2011 with more
stringent specification to avoid DEF. The fourth berth, Berth No. 4 was put under monitoring at that time. In
light of an increase in the number of cracked blocks in the most recent observation and in line with the
earlier service berths repair and replacement work, repairs to this existing Service Berth No.4, has been
initiated.
Part 2 - New Berth for MARPOL Reception Facilities
i) MARPOL 73/78 is a marine pollution control convention under International Maritime Organisation
(IMO) that ensures that the signatories shall provide reception facilities for ship generated wastes.
State of Qatar has ratified MARPOL 73/78 all annexes.
ii) For the partial fulfilment of the obligations under the MARPOL Convention, a berth with basic
provisions to receive ship generated waste is to be constructed. The facilities and plant to receive,
treat and dispose the effluents will be executed separately under a different contract.
iii) A barge will collect the slops and liquid waste from ships at other locations and deliver the waste
cargo, which will be received at this berth.
iv) To utilise the new berth to the maximum, the importation of stone aggregates through this berth is
under consideration.
1.2 Project Objectives
The Project objectives are:
1) To repair Service Berth No.4, which has cracks in the mass concrete blocks making up the quay wall and
to construct a bund to demarcate the disposal area at Wakra Dock to contain the dumped material within
the bunded area?
2) To construct new berth for MARPOL reception facilities.
