"Reestablishing those connections is a step-by-step process" and will take a while, Rice said.
Harris Beach's offices on the 22th-24th floors didn't sustain damage, but the firm did have some file storage in the basement, Kedley said. Fortunately, those files were backed up electronically, he said.
Harris Beach had to get new equipment, printers and laptops, Rice said.
"Clearly everyone's business routine was completely disrupted by that. It's not a matter of clicking a switch," he said.
Kedley said the building recently received a green sticker, meaning it's safe and the building is allowed to resume operations.
"That allows us to get our facilities and IT folks back on the ground in that building," Kedley said.
And the building was planning to switch back to Con Edison power from generator over the weekend.
"Everybody wants to go back downtown," Kedley said. "Things are never the same" in temporary space.
Harris Beach has flood insurance and insurance for business interruption, he said, adding "that's not to say we won't experience some economic hit for portions of the cost because some things won't be covered."
The disruption will ultimately cost the firm at least $50,000, which is the firm's insurance deductible, he said.
