Phil Sandlin, vice president for Bradford/Corfac International in Fort Worth, says Omaha-based Tenaska did look around before sitting down to rework the pact for its regional office at 1701 E. Lamar Blvd. in North Arlington. "They got themselves comfortable with the market and what's available in that market," he says, adding "there aren't very many larges spaces in North Arlington."

Sandlin tells GlobeSt.com that the eight-year tenant's 20,890-sf lease had three years to go before expiration so the deal was packaged as a co-terminus expansion with a five-year term and extension. "The ability to extend and on-site security was a plus for them," he says. Talks began about six months ago.

Tenaska's office takes up the entire first floor of the building's east wing and now part of the west wing's main level. Prior to the expansion, the independent power producer was tied in size with Texas Health Resources. Gary Walker, president of SCM Real Estate Services in Arlington, and his broker, Renee Efimoff represented the tenant.
