The month of April saw major progress, as expected, in the testing and pre-commissioning of power, CCTV, telecommunications, fire alarm and detection, and traffic control system. Testing was ongoing while final installations of parts of these systems were being completed. This included OCC control room equipment and workstation connections and use and installation and commissioning of the VDU. Over all commissioning by ABB was at approximately 50% at end of April.

All main tunnel and evacuation tunnel lighting was operational from local control by late April.

The Contractor continued with installation works that should have been finished months ago at STP and NTP and in VMB. All substations except S/S#8 at STP were energised by end of April. The MV, fibre optic and road lighting cables were installed along the south road after months of delay in slow excavation of the cable trench.

On site training began in April with HAMADECO staff assigned to accompany PKIII trainers during field final installations and checking.

Installation of road lighting poles and luminaires along the south road and connections was almost completed as was the last road lights from NTP to Highway 1.

Final assembly of the Radio Rebroadcast system was ongoing in Belgium and FAT is expected in May.  Completion of installation works continues for parts of CCTV, traffic control, telephone, and for general electrical works.  PKIII have scheduled 1 month for completion of RRB in June. Main panel hardware and antenna mast has not yet been delivered.
