Thank you very much.
The main decisions made by the House of Commons, which Mr. Patrice explained to you, helped the design take shape. The design process is highly collaborative and mobilizes many partners beyond Parliament, such as the National Capital Commission and Parks Canada's Federal Heritage Buildings Review Office.
Because of the importance of the design work on perhaps the most important public building in Canada, and the complexities involved, PSPC, in partnership with the National Capital Commission and Parliament, engaged the Royal Architectural Institute of Canada to obtain independent feedback on the evolving design. The RAIC brought together a group of eminent Canadian architects and design professionals, as well as a former architect of the Capitol in Washington, to form the independent design review panel shown on slide 15 to provide feedback on the design direction.
The design I will walk through today continues to be shaped through this engagement, and it is helping us find a point of balance between restoring this heritage masterpiece and modernizing it to support a 21st-century Parliament, and making it more open and accessible for all Canadians.
The first point to highlight is this: the key principle of this design is that both the renewed Centre Block and new Parliament welcome centre will respect what was there before. In this spirit, slide 17 shows that the parliamentary lawn is completely restored and lines of sight from Centre Block are maintained. At the foot of the Centennial Flame, Parliament Hill will look a great deal like it did when Centre Block closed. Traditional operation of the Hill will also be respected and traditional access routes will also be maintained.
Canadians will continue to pass by the Centennial Flame as they move up the central path toward a new, fully accessible front door to Parliament. As well, it is important to note that parliamentarians and visiting dignitaries will still be able to enter the Centre Block through the traditional entryways. As a visitor moves up the central pathway, the universally accessible front door comes into focus. The goal is for the entry to be subtle, but also for it to work intuitively for Canadians visiting Parliament Hill.
The Vaux wall and the central staircase will be returned to their former positions, and the entry will be integrated under the central staircase, with access from both the east and west.
When a visitor enters the Parliament welcome centre, as indicated on slide 18, they first enter a mezzanine. This is a secured area, but an opening allows the visitor to quickly see the layout and function of the space.
The central feature in this space is also immediately evident; the now exposed foundation of the Peace Tower and Confederation Hall both anchors the space and connects it to the Centre Block.
Stairs and elevators will be accessible from both sides to lead visitors from the main public entrance of the Welcome Centre.
Visitors will then pass through airport-style security screening, with a bypass lane for parliamentarians and dedicated lanes for business visitors. The majority of the lanes will be used by the Canadian public and visiting school groups.
Once a visitor enters the main welcome hall, there will be dedicated spaces for visitor engagement, exhibition space and an interactive theatre, as well as classrooms for school groups, which will be available for use by parliamentarians to engage schools, constituents and other groups.
Visitors will flow around the foundation of the Peace Tower as they move toward the Centre Block. Two sets of skylights will fill the space with natural light and connect it to two of the Centre Block's most iconic elements: the Peace Tower and the Hall of Honour.
Previously only visible from outside the building, there will now be several vistas of the Centre Block's defining feature, the Peace Tower. The point of interface between the Parliament welcome centre and the Centre Block will be the east and west courtyards. A visitor on a public tour will enter through the west courtyard adjacent to the House chamber and exit through the east courtyard adjacent to the Senate chamber.
As visitors take elevators up into the previously unused courtyards, they will ascend into new, light-filled spaces. The use of the courtyards will have multiple benefits, making the Centre Block more energy efficient and much more accessible. Leveraging the courtyards is critical to ensuring that the Centre Block can continue to operate both as the Parliament building and as a public building, open and accessible to all Canadians.
Visitors participating in a guided tour, those attending a committee meeting or leading other activities will exit the interior courtyard through the south hallway. Those attending question period or a vote will go up one floor using the stairs or elevator to reach a mezzanine adjacent to the Chamber gallery.
As visitors move toward the gallery, they will pass through an antechamber that will act as a sound trap to ensure that activity in the courtyard will not disturb chamber proceedings.
As a visitor enters into the new code-compliant and universally accessible gallery, the chamber will look as it always did. The heritage elements will be fully restored, but with fully integrated modern infrastructure to meet broadcasting and acoustic standards.
As Mr. Patrice said, seating design in both the gallery and the chamber floor is an area on which we continue to work hand in hand with the House of Commons to ensure that we're able to align the functional needs of Parliament and the objectives of universal accessibility. Specifically, we are working to maintain as many seats as possible in the gallery and to provide additional seats on the chamber floor to accommodate the increasing numbers of MPs over time. Further consultation with Parliamentarians, including mock-ups, will be part of the process to further develop the seating plans for the chamber.
Using slides 23 to 25, I will provide an update on heritage conservation and construction progress.
Many of the more than 20,000 heritage assets in the Centre Block have been removed for repair and restoration. Internationally recognized best practices for conservation are being followed to both protect existing heritage elements and design new features that serve modern functions.
Following the careful removal of the heritage layer, much of the building has now been taken down to the studs. The removal of asbestos is 65% completed. Approximately 16 million pounds of asbestos-containing material have now been removed. The painstaking work will be completed on floors one, four, five and six before the end of 2022, while work on the high heritage floors, two and three, including the chambers, will extend into 2023.
The following slides show before and after pictures. You can see the progress made inside the building to prepare the start of the next phase of construction to reinforce the building's structure, meet modern building codes and install new systems.
The first image is of the chamber after the hand-painted linen ceiling was carefully removed for important conservation work. The second image shows the former fifth-floor cafeteria.
Slide 28 shows progress made at the visitor entrance, located on the first floor of the building. The next slide shows the 6th floor.
The last slide in this series shows the reading room. It is now being used for rapid testing of all the workers. That has been a key part of a comprehensive strategy, with great leadership demonstrated by the construction industry, to keep the site safe and operational over the past two years.
Slide 31 shows the masonry work progressing well on the north facade. Twenty-five per cent of the north facade is now completed, which represents about 5% of the overall masonry work. This will involve the complete rehabilitation of the almost 400,000 stones on the building's exterior, requiring the complete removal and repair, and in some cases replacement, of approximately one-third of the stones. This work is extremely labour-intensive and time-consuming.
Excavation of the Parliament Welcome Centre, which we can see on slide 32, are on the right track and progressing well. In fact, 60% of the excavation is now done. To date, 26,000 loads of rocky substrate have been removed. The western section of the excavation has reached its final depth, which is 21 meters. Excavation will be done by the end of this year.
I will now look forward to some key upcoming milestones and activities. A key focus this spring will be to finalize the schematic design and then seek design endorsement in the form of a federal land use approval from the National Capital Commission.
Turning to construction, we will begin the removal of the floor slab in level one and begin excavation work in the basement and the courtyards. This technically challenging work is key to both advancing the base isolation strategy for seismic upgrading and interconnecting the Centre Block and the Parliament welcome centre.
In 2023, main excavation of the Parliament Welcome Centre will be behind us, and we will come to the end of our demolition and asbestos removal inside Centre Block. By the end of 2023, after the creation of a series of geothermic wells, we will start to pour concrete for the Parliament Welcome Centre.
In closing, the restoration and modernization of the Centre Block and the insertion of a new Parliament welcome centre into the heritage landscape is complex and challenging. At the same time, it provides a number of opportunities not only to restore this Canadian masterpiece but also to digitally equip Canada's Parliament and make it more secure, sustainable and accessible to all Canadians, enabling more Canadians to engage in our country's parliamentary tradition and democratic process. This work will ensure that the Parliament buildings are ready to serve Parliament and Canada for another century.
Thank you for your attention. We'd be pleased to take your questions.
