TRCA intends to establish a Vendors of Record for firms with the expertise, material, equipment and workforce required to supply and deliver various aggregate materials throughout TRCA’s jurisdiction. The Proponent's awarded for this Vendors of Record will be responsible for providing aggregate materials only for the aggregate categories they provide pricing for. These categories include:

• Category 1: Granular

• Category 4: Non-stackable Armour Stone
• Category 5: Round Stone

These aggregates will be required at up to 15 different TRCA construction projects at different stages of implementation and with varying demands for aggregate. These materials require adherence to strict engineering requirements and specifications. The types of projects include, but are not limited to:

• Bank/slope/channel stabilization projects, armour stone retaining walls, mechanically stabilized earth (MSE) slopes, drainage channels, revetments and buttresses;
• Waterfront development and remedial shoreline protection, including lake-filling, placement of rip rap, armour stone headlands, groynes and breakwaters;
