COTO RMC

Issues: Lack of formal structure for approvals and

publishing of documents - Road Coordinating Committee (RCC) not functioning

Lack of national research fund Need for other COTO committees to be

reactivated.

COTO RMC

Points of interest New procurement system for professional

services: Competitive selection on balance between competence and price

Preference for accredited laboratories Request for a QMS from consulting engineers

(ISO 9001 or similar) Reactivation of COLTO specification committee

– compatibility with CIDB requirements and revision
