The Proposed Project

Block 2 is the city block immediately south of Parliament Hill in downtown Ottawa. It faces the Centre Block and Peace Tower to the north. It is the threshold between city-owned and Crown-owned lands. The block is bounded by Metcalfe, Wellington, O'Connor and Sparks streets.

Our goal is to transform the block into an innovative complex that will meet the needs of Parliament and the public. The Block 2 Redevelopment project will create two new complexes (Block 2 East and Block 2 West), that will redevelop the undeveloped lands and rehabilitate/integrate several existing buildings. The redesigned block will service parliamentary functions and will also include renovated retail space.

The Construction Manager has installed construction site hoarding to ensure safe construction operations and to maintain public safety during the construction period. Following installation of the hoarding, the following work packages had been initiated and are ongoing at the Block 2 site, and have been covered under Phase 1 and Phase 2:

• Decommissioning, Demolition and Abatement: involves the decommissioning of mechanical and electrical equipment, as well as the abatement of hazardous building materials in support of interior demolition and deconstruction activities at Bate, Birks, Fisher, Marshall, Canada Four Corners and Union buildings.
• Major Site Utilities Reconfiguration/Relocates or Removals: involves the identification and/or re-confirmation of underground utilities at the Block 2 site (watermains or watermain branches, temporary storm water and sanitary sewer systems, electrical and communications infrastructure, natural gas, Cliff CHCP heating and cooling). All applicable utility and telecom provider approvals will be obtained before isolation, reconfiguration or removal.
• Block 2 East Selective Structural Demolition and Structural Stabilization: involves structural and façade stabilization activities and mass demolition to support the long-term vision and design for the Block 2. This will include masonry consolidation, interior selective structural stabilization, below-grade shoring to stabilize the foundations, and above-grade façade stabilization shoring.

Phase 3 of the Block 2 project will include the following work package:

• Mass Demolition and Residual Abatement: involves mass building demolition work at Block 2 east, and residual hazardous materials abatement to building envelope elements. All federal heritage building facades will be retained, kept and supported during the construction of this work package. Interior heritage elements have been removed and preserved as part of earlier work packages mentioned above (e.g. decommissioning, demolition and abatement). This work is generally limited to exterior elements and all structural elements to be removed. At least 90% of building demolition waste will be diverted from landfill.
