    • 3. Project Team <ul><li>Traditional Project Delivery: Design-Bid-Build </li></ul><ul><li>Client - York Region Transit </li></ul><ul><li>Architectural / LEED Consulting - Delcan Corporation </li></ul><ul><li>Mechanical & Electrical Engineering - HH Angus </li></ul><ul><li>Structural Engineering - Banerjee & Associates </li></ul><ul><li>Landscape Design - McWilliam & Associates </li></ul><ul><li>General Contractor – Bondfield Construction </li></ul><ul><li>Commissioning - Hunter Facilities Management </li></ul>
    • 4. Client Objectives <ul><li>York Region Transit (YRT): </li></ul><ul><ul><li>Continue to provide services for the increasing volume of public transportation for all nine municipalities of York Region </li></ul></ul><ul><ul><li>Conversion of an industrial building into an efficiently planned space for the smooth operation of a bus facility that stores, maintains and repairs a fleet of 230 buses as well as the related operations and administration space </li></ul></ul><ul><ul><li>Is targeting LEED Silver </li></ul></ul>
    • 5. Site <ul><li>4.5 hectares (11 acres) </li></ul><ul><ul><li>Building – 2.1 hectares (5.1 acres) </li></ul></ul><ul><ul><li>Asphalt/landscaping – 2.4 hectares (5.9 acres) </li></ul></ul>

    • 9. Existing Envelope <ul><li>Remaining cladding - either insulated metal panels or metal over lightweight concrete: 10% Siporex </li></ul><ul><li>Roof deck - 80% Siporex </li></ul><ul><li>All Siporex removed due to deterioration and compromised structural integrity </li></ul>
    • 10. Siporex <ul><li>Aerated concrete: </li></ul><ul><li>Aluminum added to a concrete slurry, where reaction causes expansion </li></ul><ul><li>Touted as a viable insulating concrete </li></ul><ul><li>Failure: </li></ul><ul><li>Panels are susceptible to moisture damage and eventual failure </li></ul><ul><li>Such was the case in this building </li></ul><ul><li>Fully recyclable </li></ul>
    • 11. Proposed Site Lay-out <ul><li>Existing asphalt to be removed due to poor condition and pour drainage & low bearing capacity </li></ul><ul><li>New landscaped frontages </li></ul><ul><li>New permeable pavement </li></ul><ul><li>New access to Keele in the southeast corner of the site </li></ul>
    • 12. Building Envelope Upgrades <ul><li>Peeled back exterior skin, where necessary: </li></ul><ul><li>Walls - Siporex panels (10%) replaced with insulated metal panels </li></ul><ul><li>Roof – 4-ply gravel on Siporex panels removed, new white reflective roof membrane on insulated metal roof deck </li></ul><ul><li>Office block - masonry cladding to be covered with insulated metal panels </li></ul><ul><li>Openings - Numerous new overhead doors on the north facade for bus entry, others on the south and west façades </li></ul>

    • 14. Structural Steel <ul><li>Local source and high recycled content specified </li></ul><ul><li>Structural steel will be removed and existing columns relocated </li></ul><ul><li>Additional horizontal bridging at the underside of the roof structure </li></ul><ul><li>Provide steel framing for wall cladding system and above new Overhead Doors </li></ul><ul><li>New galvanized steel roof deck. </li></ul>
