The federal government says it’s planning another major overhaul of the central heating and cooling plant that serves dozens of downtown Ottawa buildings.
Public Works published a procurement notice Tuesday that says the rehabilitation and partial deconstruction of the Cliff Heating Plant is expected to cost between $1 million and $5 million.

In a project unrelated to the explosion, the federal government budgeted $3.8 million in 2011 to replace two electric chillers at the plant.
