Summary from Contractor

The Contractor's site construction progress for the month of January slowed down because of shortage of LV cable and equipment. Distribution boards, power distribution, monitoring and control panels, telecommunications panels, traffic control/CCTV panels and other panels for substations did not arrive on site until mid January despite being accepted at FAT by the Engineer in early October.

At the end of December PKIII identified to the Engineer a shortage of LV power and control cables because of deficiencies in their purchasing and scheduling. As a result cabling works between equipment inside substations had not yet started at end of January. This work should have been ongoing since late November. All substation buildings had been handed over to PKIII by late December 2004, starting with availability of S/S#7 & 8 in May and S/S#5 in August 2004.

Installation of road lighting pole foundations along the south road was substantially completed as was the erection of the 9m poles and pole top luminaires. Tunnel overhead works were limited to cable ladder crossings at EP and VAC intersections with main tunnel, installation of brackets for the support of radio rebroadcast (RRB) coaxial antenna, fire sensor cable, and CCTV camera supports. Conduit and boxes continue to be installed in VAB as PKIV work progresses.

Medium voltage (MV) cable pulling began at the end of October in the main tunnel and continued in the ventilation adit and on Lang Co bridge. Approximately 90% of MV cable joints in the main tunnel have been done. The installation of MV cable from S/S#3 to S/S#6 inside the adit cannot be completed because, as with LV cable, the Contractor did not order the correct amount of MV cable and is now seeking additional lengths.

Design work at site continues on the preparation and submittal of installation shop drawings. Detailed design continued in ABB Finland on systems (Fire alarm, and radio rebroadcast (RRB).  Factory acceptance tests (FAT) were completed in early October in Finland on traffic control, lighting control, power distribution control, and main SCADA systems and on systems integration. 

PKIII turned over responsibility for maintenance of all of PKV works (OCC building and power system) to HAMADECO in January but continued to support HAMADECO until end of January.
