Thank you for the question.
I would say that PSPC, as a department and as an expert in real property, requires a review of each project. Each project is looked at based on the benefits of which materials should be used in its construction. It's not a decision that is taken across the board. It's a decision that is taken on a project-by-project basis to ensure that we are using the most efficient material, the most secure material and the material that has the smallest carbon footprint.
