As a site manager you get to enjoy the satisfaction of seeing a project from the original paper concept to a completed final and physical product. Something that many set as a goal as a site manager is a Chartered membership to the CIOB, if they are not already. A CIOB accredited course is available from The College of Contract Management: Level 4 Certificate and Diploma in Site Management. This course will give you all the knowledge you need to apply for a CSCS Black Card.
