Introduction Project Background Located in the heart of Vancouver, Canada’s Earth Tower design proposal is in the rezoning phase to re-envision the third largest C-3A-zoned site in the City of Vancouver.

It is proposed to create a 38-storey, 31,494 square meters (340,000 square foot) residential mixed-use highperformance sustainable development, constructed using mass timber with a target of achieving Passive House certification. This 38-storey building consists of three storeys of below grade parking, a six-storey mixed use podium, including office, retail and residential tower above, as conceptually illustrated in Figures 1 and 2. The podium is designed to incorporate mass timber columns and 0 3

proposed as a concrete core with a mass timber structural frame (Figures 3 and 4). It is set to exceed Mjøstårnet in Figure 1: Canada’s Earth Tower North-South Section

Brumunddal, Norway, currently the tallest modern wood building in the world.

Fundamental to the project is demonstrating an approach to urban development that prioritizes meaningful initiatives to address humankind’s impact on climate change. Equally important, is to bring focus to the influence materials have over the health and well-being of the inhabitants, and the implications to the ecosystem that result from their creation. In pursuit of these two objectives, the use of wood is critical, with its capability to address greenhouse gas (GHG) emissions in a meaningful way. By employing wood as the primary structure, the proposed development will advance the industry by altering market perceptions, providing choice, prioritizing performance, and minimizing the environmental impacts.

Balcony Mock-up: Durability & Weathering As there is an increasing demand on employing exposed timber members for architectural aesthetics in an outdoor condition, it becomes a critical necessity to provide protection that enhances timber’s durability and weathering. Coupled with finish coating that provides weather protection for balcony timber members, careful selection and installation of balcony membrane is required to provide long-term moisture protection and proper balcony edge detailing to reduce the risk of water ingress into the wood components.

Balcony Mock-up: Cost Effectiveness

Figure 18: Custom steel connection through the unitized wall panel allows flexibility in adjusting the balcony height to address zero threshold condition.

Cost savings may be realized through the use of prefabricated balconies, but costs for the use of a hoist or crane to install the balconies must also be considered to have a meaningful comparison with other balcony construction solutions. Depending on specific project requirements, on high-rise projects the tower crane is normally kept to 6-8 weeks beyond the topping out of the primary structure; in this case the addition of the balconies as prefabricated items and requiring crane lifts may or may not significantly increase that duration. The total cost of incremental crane lifting to hoist all prefabricated balconies for Canada's Earth Tower would require additional analysis to determine exact amount.

While it is challenging to do a detailed ‘apples to apples‘ cost analysis at this prototype stage, our preliminary cost analysis indicated that the cost per square feet for this balcony mock-up is higher, comparing it to the conventional solutions constructed out of concrete or steel. However, this cost analysis does not holistically reveal full life cycle cost effectiveness of a prefabricated timber balcony construction solution. Environmental cost, such as carbon emissions of using timber versus concrete or steel and locally sourced materials versus outsourced ones, should be given equal consideration when assessing the overall cost effectiveness.

Detailing should be well thought-out in terms of transition support from the interior floor to the balcony deck finish and flashing termination, ensuring proper sequencing and execution of continuous building enclosure control layers early on the design process.

While the guard attachment was excluded from the balcony mock-up due to budget limitations, it should be given enough attention early in the design process, so it does not interface with or penetrate into the wood components.

Depending on how the guard attaches to the balcony while meeting lateral load requirements, it is important to consider proper balcony edge membrane overlap, to avoid penetrating the weather membrane, and to consider proper flashing termination.

Figure 26: Final balcony mock-up photo—the guardrails were not installed due to limited budgeting. However, the perimeter guardrail would have been fastened to the steel support structure so not to interface with or penetrate into the wood components, while keeping weather membrane undisrupted.

URBAN ONE CONSTRUCTION INC.

It is the trade contractor’s responsibility to verify all dimensions and conditions on site as required to supplement the shop drawings and to ensure compliance with the contract documents.

This review does not mean that Urban One approves the original design by the consultant or the details shown on the shop drawings by the trade contractor with respect to their suitability or performance. Urban One’s review pertains only to coordination of various trades’ work and does not alter the contractual obligations of the trade contractor in any respect. This review neither relieves the trade contractor from any obligation to correct errors and omissions inherent in the shop drawings.

PW: Noted that all interior floor decking has been changed from CLT to DLT.

Presume that the plywood over the DLT will not be coated. Recommend plywood over OSB or ZIP for polyurethane adhesion. SBS base (SOprema Elastophen Flam Stick base layer) should adhere

Will need to onsite confirm adhesion of the reinforced polyurethane deck membrane (BASF, etc) to this coating on the CLT. Can easily be sanded off if not.

okay

NOTE: CLT WALL PANEL WAS REMOVED FROM SHORT SIDE TO REDUCE THE TRIBUTARY AREA FOR THE WIND LOAD

PW: Noted.

agreed, consider the KP12-UVW if left exposed for long time to keep looking good

PW: Given that the balcony mock-up will be exposed to exterior conditions, recommend using KP 12-UVW as a base coat for solar uv and moisture weather protection, with a clear top finish coat to keep wood character/ appearance.

Sansin has products available for outdoor timber application.

2% SLOPE IN STRUCTURE

decking flat or sloped with balcony? Typically flat on tapered pedestal

PW: Decking is also sloped in a way that the decking is flush against top of balcony side plates and 168mm dia. steel pipe at the balcony edge. Refer to Arch detail 6&9/A32-10.

TIMBER BEARING PANEL - SIZE DEPENDS ON SOIL QUALITY

Site conditions assumed as compacted gravel.

These 3-lam 100 mm CLT base pads could have 20 mm holes drilled near corners. 15M rebar could be sledgehammered minimum 18" into the ground through these holes (4 per base pad) providing temporary lateral fixity.

This is in combination with the use of Dayton Superior Tilt-Up Braces to paired lock blocks.

Site Visit 01: Balcony Mockup at 21551 Westminster Hwy, Richmond

Balcony Waterproofing/Flashing First ply/coating of the SBS/urethane membrane has been installed on the top surface and sides and portions of the underside at the perimeter. The remaining components to be installed include the perimeter flashing, second ply/coating of waterproofing, and the door threshold transition components. Flashing to be installed within the steel frame on the balcony side edge and over the steel angle on the front edge. The sketches below show the general arrangement.

Action Required: PW/U1 to confirm detail and U1 to install remaining components.

1.2.

Balcony Walking Surface The deck planking will run parallel and perpendicular to the balcony/facade direction on different levels. Planking support pieces (strapping) must be arranged to avoid blocking drainage from the waterproofing surfaces per sketches below. Decking must not fasten into balcony waterproofing. Potential structural/lifting restraint of the decking from the top side to be confirmed if needed per structural.

Action Required: PW/U1 to confirm decking support arrangement.

Page 1

1.3.

Balcony Installation Each balcony includes coated steel framing and through-wall connectors back to the structure, which support the CLT and DLT balcony panels. The wood balcony installation sequence appears to require a three-step process as follows: 1.

Position the wood balcony on temporary sawhorses/stands above the steel support frame to allow installation of the first ply/coating of the waterproofing membrane on the top and perimeter of the wood.

2.

Lift the support frame up to the wood balcony structure and fasten in place. If possible, other balcony waterproofing/finish items can be completed except at door threshold/building-side tie-ins. These may include portions of walking surfaces, underside finishes, and guardrails.

3.

Lift the steel structure/wood balcony as one piece and attach to the connections on the façade. Complete remaining structural/waterproofing/finishing as needed.

The façade connectors include hook bracket/bolt components to allow the connector to be lowered into place and supported without additional fasteners. The brackets currently do not include the built-in adjustability that may be needed to position the brackets, but the general installation sequence appears to be represented. A cap bolt is installed on the top side of the hook brackets to prevent lift.

Action Required: Observation

1.4.

Moisture Monitoring Setup As per the attached sensor plan, RDH will be installing moisture monitoring equipment on the mockup once waterproofing and decking is complete, and site access is in place.

Moisture pins will be left in place to log the moisture characteristics of the balcony wood components.

Action Required: PW/U1 to confirm access to upper balconies is in place.

Site Visit 02 Update: Balcony Mockup at 21551 Westminster Hwy, Richmond

Balcony Waterproofing/Flashing Mockup The perimeter flashing has been installed at Level 3. Several items require correction for the Level 1 and Level 2 install as follows: 1.

The vertical leg of the flashing at the front edge is slotted between the panel edge and the L-angle structure which is incorrect. It should extend over the exterior side of the L-angle to allow water shedding (see below).

2.

The flashing is installed with nails into the deck. It should instead be set into sealant or temporarily taped in place to avoid penetrations into the bottom membrane.

3.

The side edge flashing should include a drip edge over the structural tab (see below)

Action Required: 1.

PW/U1 to confirm detail and U1 to install remaining components. Avoid penetrations into bottom membrane ply.

2.

U1 to leave Level 3 flashing as is and install remaining membrane/components

Membrane Blistering PW noted blistering spots beneath the Level 1 SBS membrane. It could not be confirmed if these are the result of membrane discontinuities.

Action Required: U1 to cut open blisters to confirm if water is present, drain and dry wood surface if necessary, repair as necessary prior to second ply installation.

Canada’s Earth Tower: Balcony Mock-up

Decking Material Review

88

Matthew Wollin Sales & Specifications Representative Upper Canada Forest Products 604 374 5435 mwollin@ucfp.com Decking Material Review Canada Earth Tower – Mock-up Assembly June 08, 2021

Upper Canada Forest Products (UCFP) is grateful to be a participant in the Canada Earth Tower, Deck Assembly mock-up. For this mockup, two separate deck materials have been installed.

1. Accoya – Acetylated Radiata Pine 2. Thermal Ash – ThermalWood Canada’s heat-treated ash Dimensions

Deck Board 20mm x 140mm

Sub Assembly 26mm x 145mm

Clip Height Flush

Total 46 mm

Future Considerations 1.

2.

3.

4.

Expansion and contraction of thermal ash decking system Substructure ventilation and screw penetration Natural “Greying” and coating systems Deck board orientation

Expansion and Contraction of Thermal Ash Decking System Based on technical data from the Accsys Group, Thermal Ash will experience additional expansion and contraction. Over time this will result in a less even decking surface. Review of butt joints should be completed during the testing window. Please reference chart below (both installed decks are tangential sawn).

Thermal Expansion:

Substructure Ventilation and Screw Penetration Accoya recommends that a minimum of 25mm of fastener penetration be obtained for deck installations. If Accoya is used as a subframe, they suggest a minimum of 10mm between the end of the fastener and the bottom of the sub assembly board. This creates a 35mm minimum total sub assembly height from a fastening perspective.

Screw Penetration:

For typical deck applications Accoya’s technical literature recommends a 70mm ventilation space. There may be an argument that the deck system’s exposure to wind/air flow should allow for better ventilation in comparison to a traditional ground level deck. The mock-up testing should provide helpful data regarding moisture build up. Check for mold or mildew growth at the edges of the decking material.

Natural “Greying” and Coating Systems The Accoya deck was left 100% raw. Thermal Ash has a CUTEK oil-based coating that was used to help prevent surface checking. In both cases the material will naturally grey due to UV exposure. If desired, a coating system can be applied to both products to help maintain colour and prevent greying. Further information on coating systems can be found in Accoya’s technical literature.

Deck Orientation On the parallel deck design considerations should be made to ensure the secure fastening of the shortest angled deck board. In this orientation an additional sub-frame support may be required.
