The GSI TBL tool is intended to find the appropriate balance of grey and green infrastructure in Calgary and to evaluate which green practices hold the most promise. 3. This procurement process is not intended to create, and, will not create, a formal, legally binding bidding process. It will instead be governed by the law applicable to direct commercial negotiations. 4. Anticipate project completion is 2025 September 30.
