There are various studies that we have carried out that are public, and we've even shared them with the unions, in terms of the cost efficiency of the real property program, benchmarking ourselves against—and this is very important to understand—other corporate real estate entities, both in the private sector and more importantly at government levels, that show we basically have twice as many employees as other like organizations who manage the same type of property.
We also have another study, which has been carried out by CB Richard Ellis and Tiree Inc., that shows that the efficiency span within Public Works is approximately 20% higher than that of private sector entities.
Even when we outsourced our own property management to a third-party service provider, in the initial phase in 1996 we saved $20 million. And then further, when we retendered, we saved an additional $18.7 million per year, on an annual basis. So just through the efficiency of our own operations, we were able to pick up $40 million just by outsourcing the property management to the private sector. Also, when you benchmark us against other like organizations, we have twice as many employees on a per metre basis.
