Memo to : Executive Committee

3rd November, 1987

The underlying procedures and controls of both HCCM as well as the JVC-CM have been examined by the contractor and the JVC management in depth. It has been concluded that, although the procedures adequate in concept, it is necessary to implement a programme of improvement measures to ensure that they can be used successfully on site. The major areas of improvement include:

Mobilization of additional qualified staff, and strengthening of quality supervision and control actions in both the HCCM and the JVC's construction team and QC surveillance team.

Adaptation of the existing procedures and controls (which are taken from French projects) to local conditions including detailed instructions, more specific check procedures and improved recorda.
