CalPERS, the pension giant for public employees in California, has refreshed its “spring-fed pool” of agencies for services like crisis communications and writing, following a fall RFP process.

The pension system, which ended September with an investment portfolio of $219.4B and counted more than 1.6M members as of June, earmarked six vendors for crisis services as-needed over the next four years, including Weber Shandwick (Los Angeles), Burson-Marsteller (San Francisco), Ogilvy PR Worldwide (Sacramento), Halldin PR (Rocklin), Edelman (Sacramento) and Booz Allen Hamilton (San Francisco). That group was also tapped for its media training pool.

Burson also got a nod for video and multimedia work, while Weber Shandwick and Booz were designated for specialized benefits communications efforts.

CalPERS, which also selected pools for writing/editorial, marketing and A/V work, said it will use the pre-qualified groups of firms through June 30, 2016.

The pension giant employs more than 2,300 with a budget topping $334M.
