How to become a delay analyst?

I hope someone can give me advice on what should be my next move to become a delay analyst.

I have been a planner for a number of years (8) with plenty of experience of EOT's and I am also due to graduate next month for a MSc Construction Law & Arbitration (Dissertation was about Delay and Disruption techniques).  This has give me MCIarb letters and was considering doing the APC route for the RICS, however, being a contract planner would be difficult to gain this experience for RICS.

I notice a few planning experts have come from the QS route.  IS this experience neccesary to become a claims consultant/delay analyst?  Also, would i need to take a step back in pay to train as a forensic planner for a law firm say?

I feel this website would be the best for this advice.

Thanks
