Rubin and the willingness of their managers to listen to them. Having access to management and having their voices Low-Key Firm Has Core Niche heard is important to today’s employees,” says Pierson. One important intangible for retaining young designers is the willingness of management to listen and, if warranted, act on their concerns. This means providing a vehicle for young peoples’ voices to be heard. For example, AECOM has an innovation challenge where teams offer ideas for solving common problems. “We have hundreds of entries each year. We have imple- mented many of these ideas, even if they didn’t make the top 10 finalists,” says Morriss. For some firms, the acceleration in the consolidation of the industry is actually helping staffing concerns. “Whenever you have a major merger, the technical and management talent in the affected firms start getting scared,” says Pierson. “We’ve picked up a lot of talent New York City-based AKRF has kept managing permitting and from firms like AECOM and CH2M who came to us, a low profile since its start in a compliance for a $600-million rather than wait for us to recruit them.” Manhattan loft in 1981 as an early clean-burning combined-cycle specialist in the then-new field of power plant in Woodbridge, N.J., Youth Movement mandated project environmental with the firm’s mission including review, as its website notes.
