Posted By Peter MacDonald After the CTA card came the CSCS card, now I have been to a basic presentation of the ACE card which apparently will supercede all previous cards. Can someone tell me why the ACE card is required or give me some good links to further information. On a similar note, does a safety qualification such as a Nebosh 1/2 or other accredited course prove your competence to the Main Contrcators Group or do you require to sit the CITB 5 day course. Pete
