Our team has been retained by UBC Social Economic Development Studies (UBC SEEDS) to redesign East Mall between Stadium Road and Agronomy Road in attempt to better accommodate sustainable transportation modes. The corridor’s current conditions do not accommodate the high amount of pick-up/dropoff traffic during the evenings, and do not promote sustainable modes of transportation. This report will provide and in-depth review for the detailed design of the transportation, structural, municipal, and environmental disciplines. Our recommended concept involves shifting the existing median East to separate vehicle travel lanes and bike lanes, reconfiguring the intersection of Thunderbird Boulevard and East Mall and upgrading the existing signal, and widening the segment from Thunderbird Boulevard to Agronomy Road to accommodate a new bi-directional bike lane. This design will improve the safety of cyclists, provide an abundance of green space for pedestrians, and reduce conflicts between vehicles and cyclists at drop-off pick-up zones while retaining parking for residents and users of the nearby facilities. An assessment of the existing utilities was conducted to identify impacts on the existing utility networks. The proposed reconfiguration is not expected to affect the system demands the water distribution and sanitary sewer systems. A stormwater management strategy has been developed on site, and the final corridor reduces the captured stormwater volumes within the project area. Specifications for the new permeable concrete cycling lanes and sidewalks have been developed, including an aggregate reservoir base to detain major storm flows for natural infiltration into the subgrade. The new pedestrian canopy consists of W200x31 section profiles for the columns and cantilevers with tempered glass panels mounted as the decking. The structure is 66.86-metres in length and will be constructed along the South side of Agronomy Road. The greenspace consists of the plantation of several new tree species to further improve the aesthetic of the corridor. Additionally, the greenspace has a community garden composed of various flowers to encourage people to gather and enjoy the surrounding landscape hence building the community. Estimated budget for the proposed solution will be $5,163,449 which includes labour, materials, operation & maintenance and a 15% contingency. Construction work will begin on May 2021 with a completion date of December 2021 with a duration of around 9 months.

SITE OVERVIEW Located on the University Endowment Lands, East Mall runs parallel to Westbrook Mall and is an important point of access for the UBC campus and bears a high volume of traffic on a day-to-day basis. It is a wide road with a large median strip separating single travel lanes. From 16th Avenue to Agronomy Road, East Mall contains two shuttle bus stops, a street bike lane, and a generous amount of curb side parking that also serves as a pick-up/drop-off zone to numerous sports fields and recreation centres. The current design poses several issues including speeding, cyclist safety, overdemand for curb side parking, pedestrian crossing safety, and lack of usable green space. Figure 1 and Figure 2 below show the current conditions and project site location. 1.2. PROJECT SCOPE The scope of work for this project consists of client required objectives as identified below. This report will address each objective and provide some insight on the design process, including calculations, technical drawings, and construction specifications. A summary of the major components of this project are: 1. Upgrade the existing East Mall corridor to promote sustainable modes of transportation and incorporate traffic calming measures to reduce travel speeds 2. Improve liveability along the corridor by reducing the possibility of vehicle conflicts with pick-up/drop-offs, pedestrians, and cyclists 3. Minimize impacts to the existing utility networks and prepare a stormwater management strategy aligned with UBC’s sustainability initiatives Figure 1: East Mall Figure 2: Project Location 8 4. Incorporate a pedestrian canopy along Agronomy Road that prioritizes comfort, safety, campus aesthetics, and cost 5. Prepare a Class A cost estimate and detailed construction schedule 1.3. STAKEHOLDER MANAGEMENT A stakeholder study has been completed to ensure the project accounts for all requirements. Our team identified the relevant stakeholders, developing a consulting plan, and reviewing feedback. Table 2 outlines the relevant stakeholders and their importance to the project. Table 2: Stakeholder Identification Stakeholder Association to the project UBC Social, Ecological, Economic Development Studies (SEEDS) The client UBC Students, Faculty, and Staff Primary users of the corridor and pedestrian canopy Ministry of Transportation and Infrastructure Governs transportation policies within BC TransLink Provides transit services along and nearby the corridor UBC Water & Energy Services Major utility owners within the corridor Musqueam First Nations Are the traditional, ancestral habitants of the territory UBC Neighbourhood Association Residents that live near the construction project UBC Properties Trust Manage the lands adjacent to the corridor The feedback provided by the stakeholders was critical to establishing an effective final design. Contact has been established with each of the stakeholder to gather information regarding their issues and concerns. Based on the feedback our team received from stakeholders, our team is confident that the project will receive full support during construction. We will continue to reach out to our identified stakeholders before, during and after construction and address any issues that arise. 9 2.

DESIGN CONCEPT Figure 3: Streetmix cross section of our East Mall Design 10 Our redesign of East Mall features a full reconstruction of the boulevard. The main feature of this configuration is the shifting of the existing median to the east side of East Mall and moving all the vehicle travel lanes to the west side. Additionally, new traffic calming measures will also be implemented along East Mall to reduce the speed of traffic. This new location of the median will improve the safety of pedestrians and cyclists as it creates a natural separation from the vehicular traffic. Improved access to this area also adds a variety of land use options, and will function as a greenspace featuring new landscaping and space for community garden boxes or public art. A new pedestrian canopy will also be constructed along Agronomy Road and provide shelter for bystanders. A stormwater management strategy has also been prepared centred around the use of permeable pavement for new cycling paths and sidewalks. Table 4: Summary of design objectives and features Discipline Design Objective Design Feature Transportation • Encourage use of active transportation modes • Reduce speeding along East Mall • Reduce vehicle – cyclist conflicts at pick -up drop – off zones • Retain ease of access for current residents • New 4.0m bi-directional greenway • Reduced travel lane widths • Dedicated drop off pick zones with no parking at any time • Retains parking on both sides of the road Structural • Encourage walking along Agronomy Rd. by implementing a pedestrian canopy • Comfortable and safe to use • Cost considerations • Fit with campus architecture • Spans the full width of sidewalk • Design was inspired from existing UBC bus loop to fit campus architecture • All structural components are the same size and thickness in order to save cost Utilities • Ensure post-development demands on UBC utility networks are within pre-development levels • Capture and keep stormwater on-site wherever possible • Reduce travel lane widths and introduce permeable concrete sidewalks and cycling lanes • Provide stormwater detention reservoir in aggregate base of permeable concrete Greenspace • Encourages active modes of transportation • Creates a barrier from vehicle traffic increasing safety of users • Minimize demand on UBC distribution networks and capture stormwater on-site • Planation of new tree species long median • Community gardens at various points throughout median • Use absorbent topsoil in landscaped areas to promote infiltration Construction • Minimize disturbances to surrounding residents • Existing utilities will remain in place and in-service during construction 11 3. TRANSPORTATION DESIGN This section will describe the design considerations relating to the roadway including roadway dimensions, intersections upgrades, and signage plans. 3.1. ROADWAY DESIGN Roadway design was done in accordance with the Geometric Design Guide for Canadian Roads, written by the Transportation Association of Canada (TAC), Engineering Design Manual from the City of Vancouver, as well as the British Columbia Active Transportation Design Guide. Key requirements include: all roadways to have a minimum crossfall of 2.0%, minimum vehicle travel lane width must be 3.25m or greater, grade of proposed alignment must not exceed 10%, and minimum sidewalk widths of 1.8m. Other factors considered in the detailed design include sightline requirements, driver comfort for sag and crest curves, as well as signal timing plans for the proposed signal upgrades at the intersection of East Mall and Thunderbird Boulevard. Software packages utilized in roadway design include AutoCAD and Civil 3D, and intersection analysis and timing plans were done with the aid of Synchro 6. Traffic signs were designed in accordance to the Manual of Traffic Signs and Pavement Markings from the British Columbia Ministry of Transportation and Highways. 3.1.1. ROADWAY CROSS SECTIONS Roadway cross sections for the newly designed East Mall segment must meet the requirements set out in section 410 in the TAC Geometric Design Guide for Canadian roads. In the proposed design, travel lane widths are set to be 3.30m wide, which satisfies the 3.25m minimum lane width for road segments with a design speed between 50km/h to 70km/h. Roadway crossfall in the design is 2.5%, which satisfies the TAC requirement of having a crossfall of 2% or greater, which is needed in order to provide adequate drainage for the road surface. 2.5% crossfall was chosen in consideration with the climate of the area which experiences high amounts of annual precipitation, and the higher crossfall will assist in facilitating drainage. Existing parking is retained in the new design with 2.4m parking lanes on both sides of the road. 2.4m was chosen to balance the goal of keeping vehicle speeds down on the segment by reducing the amount of space available to drivers, while providing enough room for parked vehicles. Sidewalk widths for the new segment are designed to be a minimum of 1.8m throughout the segment. 1.8m provides enough space for pedestrians to feel comfortable, safe, and allows for movement in both directions. A good sidewalk network is vital in encouraging more users to choose active transportation modes such as walking or cycling. Lastly, the multi-12 use pathway in the design is 4.0m, surpassing the required 2.7m as required by the British Columbia Active Transportation Guide (BCATG). A wide facility provides users more space to travel on the corridor and encourages more users to make trips with modes like cycling, walking, skateboarding, and rollerblading safely and comfortably. Having good a greenway network is also beneficial for the UBC campus as it allows for better accessibility for the future Stadium development, which is projected to add thousands of units of occupancy. Table 5: TAC Geometric Design Guide – Roadway Width Requirements 3.1.2. ROADWAY PROFILE The roadway profile was also designed to meet the requirements set out in the TAC Geometric Design Guide. Key requirements for the profile of the roadway include grade requirements and sightline requirements. The roadway profile primarily depends on the existing natural topography of the area, which is mostly flat. Hence the proposed roadway will largely overlap with the existing roadway profile and does not contain large elevation changes, with the biggest grade change at 4%, which is below the 10% maximum grade requirement outlined in the TAC Geometric Design Guide. When designing the roadway profile, sightline distances were also taken into consideration in order to satisfy the 65m sight distance for a roadway with a design speed of 50km/h. The length of the crests and sags were also calculated in accordance with best practices currently used in North America. Crest and sag lengths are important to rider comfort as well as stopping distances. Sample calculations can be found in the attached Appendix C. The figure below showcases the roadway profile of the proposed design. 13 Figure 4: Roadway Profile of Proposed Design 3.2. THUNDERBIRD BOULEVARD AND EAST MALL East Mall runs parallel to Westbrook Mall and Marine Drive and is one of the few roads that run North-South on the UBC Campus, providing key connections to locations such as the Health Sciences Parkade and Thunderbird Stadium. A traffic analysis on the intersection of Thunderbird Boulevard and East Mall will be provided in detail throughout this section. 3.2.1. EXISTING CONDITIONS AND ISSUES Currently, the intersection of Thunderbird Boulevard and East Mall is controlled by an existing pre-timed signal. The intersection services around 800 vehicles in the AM peak period and around 1150 vehicles in the PM peak. A majority of the vehicle traffic in the AM period are vehicles heading northbound into the campus, while in the PM period most vehicles are heading south and leaving the campus. The existing configuration is as follows: The South, West, and North approaches all have one receiving and departing lane, while the East approach has one receiving lane and two departing lanes, one dedicated to a left turn movement and the other for through and right movements. The intersection also sees high pedestrian volumes, with around 300 crossings in both the AM peak and PM peak periods. Cyclist volumes should also be accounted, as there are 14 around 130 cyclists in both the AM and PM peak periods. The following figure shows the vehicle volumes serviced by the intersection: Figure 5: Existing Vehicle Volumes at intersection of Thunderbird Boulevard and East Mall As shown in Figure 5, there are many vehicles making the westbound-left movement in the PM peak period, and the current traffic signal is not capable of providing a protected left turn movement for those motorists and is a bottleneck in the system. 3.2.2. PROPOSED DESIGN CHANGES AT THUNDERBIRD BLVD AND EAST MALL To better facilitate pedestrian and cyclist movements, it is proposed that vehicle travel lanes on the North approach to be moved to the west side of East Mall, allowing the existing northbound lane to be converted into a dedicated bi-direction bicycle lane with bollards acting as a barrier to vehicle traffic. The goal behind this design is to prioritize active transportation modes and provide additional capacity for cyclists and pedestrians. Having dedicated conflict paint will provide users of the greenway a safer experience crossing the intersection by making drivers more aware. A bi-directional bicycle lane makes full use of the existing road space and encourages drivers to slow down due to having less buffer space. The proposed design also includes a full 15 signal upgrade on the intersection to allow for protected westbound left turn movements in the PM peak period to alleviate total intersection delays. To accommodate this, induction loops are to be installed on the westbound left turning bay on the East approach. Section 3.2.3 will discuss the rationale behind this upgrade and provide additional analysis and justification. The figure below highlights the proposed changes to the intersection. Figure 6: Proposed Design at Thunderbird Boulevard and East Mall 3.2.3. SYNCHRO ANALYSIS Intersection performance analysis at Thunderbird Boulevard and East Mall was performed using Synchro. The performance of the intersection with the addition of a protected westbound left movement was compared to the existing conditions. The results from the Synchro model showed that in the AM peak period, having a protected westbound left phase decreased the performance of the intersection due to the low volumes. Therefore, it is recommended that the AM peak period retain its current timing configuration. However, in the PM peak period, having a dedicated phase for vehicles making the westbound left movement decreases the delay from an estimated 43 seconds to 22 seconds while maintaining the same overall intersection delay. The 16 results from the Synchro analysis are shown in the table below. A sample Synchro report can be found in Appendix I.

AGRONOMY ROAD AND EAST MALL The intersection of Agronomy Road and East Mall is north of Thunderbird Boulevard and is the next intersection for users heading north on East Mall after passing Thunderbird Boulevard. This section will highlight the challenges currently posed on the intersection and the proposed changes to tackle these challenges. 3.3.1. EXISTING CONDITIONS Unlike the intersection at Thunderbird Boulevard, the intersection of Agronomy Road is much narrower and supports larger volumes of pedestrian activity due to its proximity to the UBC Centre for Advance Wood Processing and nearby businesses such as the Starbucks at the southeast corner of the intersection. For this report, vehicle volumes on the intersection are assumed to be lower than the intersection of Thunderbird Boulevard due to pedestrian activity as count data was not available at the time of the study. 3.3.2. PROPOSED CHANGES Sticking with the goal of improving active transportation along the corridor, improvements at the intersection of Agronomy Road and East Mall include installing conflict paint and elephant’s feet to help facilitate crossing of cyclists and continuing the bi-directional protected bicycle lane originating from Thunderbird Boulevard. The bi-directional bicycle lane is set to terminate at the Agronomy, but the conflict paint markings will allow cyclists 17 to continue northbound on East Mall and provide southbound cyclists a safe connection onto the greenway. The figure below shows the proposed changes at the intersection. Figure 7: Proposed Changes at the Intersection of Agronomy Road and East Mall 3.4. SIGNAGE PLAN The signage plan was designed in accordance with the Manual of Standard Traffic Signs & Pavement Markings from the British Columbia Ministry of Transportation and Highways. Many of the new proposed traffic signs are due to the greenway shifting the travel lanes to the east side of the boulevard. Due to the future Stadium Neighbourhood changes, two zebra crosswalks will be added to facilitate anticipated foot traffic growth on the south end. Additional time-limited parking spots will follow the current design, indicated by white paint. The proposed signage plan can be found in Appendix A. 18 4. STRUCTURAL CANOPY DESIGN The detailed structural design and analysis of the proposed pedestrian canopy is outlined in this section. The canopy structure will be made up of wide flange steel beams and columns with tempered glass panels. The structure will be constructed on the south side of Agronomy Road, due to the existing awnings and trees/shrubs on the north side the north side that would obstruct the proposed canopy. As shown in Figure 8 below, the canopy will have one 12.73-metre section and one 54.13-metre section separated by the parking lot driveway. The total length of the structure will be 66.86-metres. Figure 8: Pedestrian canopy plan The detailed design process consists of sizing the main structural members, designing the connections, and sizing the foundations. Technical drawings and specifications for the canopy can be found in Appendix A. 4.1. DESIGN LOADINGS The loading on the structure was determined in accordance with NBC 2015 and consists of dead, snow, and wind loads. Live loads and earthquake loads were not included in this analysis. The considered loads will determine the member sizes and connection detail based on Ultimate Limit States or Serviceability Limit States. Since the canopy structure will not have live loading, the design of the members and connections will be governed by serviceability requirements. A summary of loads is given below: 19 Table 7: Summary of load combinations used for analysis Case NBC 2015 Load Combination Load on Cantilever [kN/m] Load on Column [kN] 1 1.4D 1.06 5.85 2 1.25D + 1.0S or 0.4W 2.42 10.54 3 1.25D + 1.5S + 0.4W 3.59 14.75 4 1.25D + 1.4W + 0.5S 3.19 13.31 Serv. 1.0D + 1.0S + 1.0W 3.31 13.37 4.1.1. SNOW LOAD Snow loading for the structure were determined in accordance with NBC 2015 Clause 4.1.6. NBC specified a 1.8-kPa 1-in-50-year ground snow load for the Vancouver City Hall region. The importance factor for this structure was assumed to be 1.0. The final snow load to be used for analysis was 1.64-kPa. Further detailed calculations can be found in Appendix D. 4.1.2. WIND LOAD Wind loading for the structure was determined in accordance with NBC 2015 Clause 4.1.7. The external and internal pressure cases were calculated, and both resulted in a wind uplift of 1.20kPa. The reference velocity pressure used was 0.45-kPa for the Vancouver City Hall region and the assumed importance factor was 1.0. Further detailed calculations can be found in Appendix D. 4.2. STRUCTURAL ANALYSIS The analysis completed on the structure consisted of a typical section (ie. cantilever and column) with fixed joints and supports. Loads from the previous section were applied as shown in Figure 8 below. The snow load was applied with global projected coordinate system, wind load was applied in the local coordinate system, and dead load was applied with global coordinate system. The analysis model is shown in Figure 9. 20 Figure 9: Loads inputted into S-Frame Figure 10: S-Frame analysis model All ultimate limit states requirements as specified by NBC 2015 were met. See Appendix D for the code checks from S-Frame. The wide flange section that resulted from serviceability limit states was a W200x31 section profile. The deflection at the outer edge of the cantilever beam due to the serviceability load combinations was 33mm. A L/120 deflection requirement results in a maximum displacement of 30mm. As a result, a standard 10-millimetre thick, 100-millimetre-high stiffener plate will be added on both sides of the top and bottom connection. See Appendix A for detail drawings. 4.3. CONNECTION DESIGN The top and bottom connections as identified in Figure 9 above will be a fixed moment end plate design with similar hex bolt layouts. The end plates will be welded to the column using a fillet weld 6-millimetres thick all around the wide flange section. Three checks on the connection capacities due to internal bending transfers were completed. The prying force on the end plate, yielding of the end plate, and strength of the welds were all passed for both connections. See Appendix A for connection details and Appendix D for calculations. 4.4. FOOTING DESIGN The plan dimensions of the footing were initially determined based on the soil type obtained from the Piteau Geotechnical Report. The specified soil type was dense sand with a soil bearing capacity of 150-kPa (based on NBC 2015 Table 9.4.4.1). The resulting plan dimensions are 0.7-meters wide by 1.2-meters long. The depth of the footing was found based on the required overturning resistance of the canopy loads. A depth of 21 1.3-meters was found to be sufficient to resist the overturning moment. See Appendix A for connection details and Appendix D for calculations. 4.5. CONSTRUCTION CONSIDERATIONS A construction plan was developed in accordance with NBC 2015. Since the location of the pedestrian canopy will be in a relatively high traffic area, construction fencing, and barricades will adhere to Clause 8.2.1 of NBC 2015 during weekdays. Construction of the canopy shall occur inside an enclosed area with at least 2.0-meters of distance between any adjacent pedestrian areas. Additionally, excavations for the canopy footing shall be kept clear of water to prevent soil and water contamination, and necessary shoring or bracing shall be installed. Proper pedestrian and vehicular traffic management should be implemented as necessary and construction waste materials should be disposed of appropriately. 22 5. UTILITIES DESIGN The following section details the municipal utilities engineering design including the water, sanitary, and stormwater network components. 5.1. EXISTING UTILITIES An initial assessment of the existing utilities has been conducted, based on information provided by the client. While a PDF displaying a plan view of the underground utilities was provided by UBC Seeds, titled UtiilityMasterMap2019, it is not up to date nor high enough resolution to determine accurate alignments and dimensions. As-built drawings for the project area were not available, and so no detailed location and depth information could be found. Figure 11 below shows a snippet of the master utility map. Utility relocations and diversions do not fall under the original scope, and so were not considered for this project. Further, certain utilities are likely to fall under different ownership groups such as FortisBC, and the decision to conduct realignment ultimately does not fall under the project teams’ control. The proposed design is generally limited to the road surface and does not introduce any major underground elements that would require the current alignments to be moved. However, an analysis of the water, sanitary, and stormwater systems was conducted to determine if upsizing will be required and can be found in the subsequent report sections. Figure 11: Existing underground utilities 5.1.1. UTILITIES DESIGN The following table summarizes the existing utilities identified based on available resources, as well as approximate dimensions, typical depths of cover, and key comments: 23 Table 8: Existing Utility Summary Utility Dimensions (mm) Typical Depth of Cover (mm) Comments Communications 400 x 600 600 • Not shown on master utilities plan, but identified by UBC SEEDS • Likely third-party owned Electrical 400 x 600 600 • Not shown on master utilities plan, but identified by UBC SEEDS • Likely third-party owned Natural Gas  50 to  100 600 • Service connections not shown • Likely third-party owned Water  200 to  250 900 • Likely to be small diameter • Service connections not shown District Energy (Water) Unknown Unknown • Not shown on master utilities plan, but identified on UBC Energy publications • Located along Thunderbird Boulevard • High-temperature pressurized main Sanitary  200 to  450 1500 to 3000 • Manholes, service connections, and cleanout information not available • No distinction made between gravity and pressurized mains Storm  300 to  900 1500 to 3000 • Likely to be large diameter mains along East Mall • Manhole and service connection information not available While the communications and electrical duct banks were not shown on the plan view sheet, typical construction practice is to install close to the surface and underneath the main roadway or sidewalk. Based on an inspection of the project area, most buildings directly facing East Mall are only reachable by mains along the corridor and so must have service connections not shown in the mastery utility map. Service connections are generally installed perpendicular to the main utility with less depth of cover. Other major infrastructure components like manholes are visibly present in the project area, though they are not indicated in the utility map. 5.1.2. CONSTRUCTION CONSIDERATIONS Based on the City of Vancouver’s Engineering Design Guides, the geotechnical requirements for bus lanes call for a minimum of 50mm of surface mix, 180mm of base of mix, 150mm of 19mm crushed granular base, and 300mm of 17mm crushed granular base for a total excavation depth of 680mm beneath the road surface. Communications, electrical, and natural gas conduits will fall directly in the excavation zone and water mains 24 are likely to be encountered where over excavation is required. Information on the district energy system is not available but is likely to have similar specifications as the water mains. Based on the estimated depth of cover, sanitary and storm mains are unlikely to be encountered during construction. However, service connections to adjacent properties are generally found at shallower depths and could be located in the excavation area. Sanitary and storm sewer manholes also fall within the reconfiguration area, though are identifiable prior to construction. As such, safety during construction is the primary concern, and our team has outlined considerations in the General Notes of the drawing package and the Construction Specifications including the following key requirements: • The Contractor will perform a detailed utility locate to confirm the alignments and depths of existing utilities prior to commencing construction • Hand excavation will be required within 300mm of any pressurized utilities • The Consultant will be contacted prior to any construction work requiring the removal or shutdown of an existing utility 25 5.2. WATER AND SANITARY UBC owns and operates both the water distribution and sanitary sewer networks on campus. Both have been identified within the East Mall corridor, as well as the Academic District Energy System which intersects along Thunderbird Boulevard. Sheets W101 and S101 in the drawing package provide plan-view drawings of these systems, as well as construction comments and notes. The focus of this project is a road reconfiguration for East Mall and does not introduce any new developments to the project area that need to be serviced by the existing water or sanitary networks. As such, the post-development demands on these underground utilities will be unchanged from the pre-development demand. A survey of the existing hydrants was conducted, and no relocation will be required for the final design. No improvements will be required, and thus the emphasis will be to maintain service and minimize disturbances during the construction phase. Figure 12: Water Utilities Map at Thunderbird Blvd. and East Mall In addition to the previously identified construction considerations, stub lengths and pipe loops have also been identified in the water distribution system. Flow can often become stagnant in these areas, and potentially lead to health concerns if the system is not adequately maintained. UBC will be contacted to determine if these sections should be removed or grouted. Hydrants, manholes, and other ground-level infrastructure 26 should remain in place during construction. Service should not be stopped without first getting approval from both the Consultant as well as UBC. Without further information, the sanitary and district energy mains should both be considered to be pressurized and treated as high-risk. Excavation should be done by hand around the mains to avoid potentially damaging them. 5.3. STORMWATER Ensuring that UBC’s sustainability initiatives were met was one of the main design objectives, and proper stormwater management plays a critical role in this. The existing corridor has a paved roadway with a shared bicycle lane and an adjacent sidewalk drained through catch basins along the curb line. Rainfall is then directed into the stormwater sewer system, which is owned and operated by UBC. From Thunderbird Blvd. to Agronomy, runoff is directed into the University’s Western catchment and out through a creek adjacent to Wreck Beach. South of Thunderbird, runoff is directed along into the University’s 16th Avenue Catchment area and the majority drains out within Pacific Spirit Park. While a detailed control plan is not required based on UBC’s technical guidelines, the following section outlines the management philosophy for the site. 5.3.1. MANAGEMENT Throughout the design process, our team minimized runoff and the amount of impermeable area introduced wherever possible. Decreasing the travel lane widths and specifying permeable pavement for the new sidewalks and bicycle paths are two key features of the new corridor that reduces the impermeable area. These impermeable surfaces are associated with the fast runoff response in the system and reducing the tributary area that drains into pipe network reduces the total runoff volume and by extension reduces the peak flow entering the system. The capture method for the roadway has remained the same as before, with both directions sloped towards the adjacent gutter line. According to the City of Surrey’s Design criteria, catch basins should serve a maximum catchment area of 500m2. With a typical road width of 12.2m, catch basins will be spaced every 35m including a factor of safety. However, this spacing is actually less than what is currently being provided by the existing catch basins. Furthermore, as the stormwater main does not need to be upsized, removing the existing basin leads then installing new ones is redundant and adds unnecessary construction complexity. As a result, catch basins on the roadway will be relocated to follow the new curb line and the leads will be adjusted to suit. Existing basins should be reused wherever possible as long as they are in adequate condition to reduce construction waste. 27 Figure 13: Typical Catch Basin Landscaped areas like the greenway do not drain into UBC’s system, and precipitation is expected to percolate into the groundwater. In accordance with UBC’s technical guidelines, the greenspace will also feature a 450mm layer of absorbent topsoil to promote infiltration. More extensive gardening and planting on the proposed greenspace helps to improve stormwater quality by acting as a filter prior to percolation. Similarly, the permeable concrete also allows stormwater to be kept on site instead of captured into the sewer system and conveyed away. From the Integrated Stormwater Management Plan, UBC’s preferred implementation strategy is to use detention to capture flooding. As such, the permeable concrete was also designed to have A base aggregate reservoir capable of storing a major storm event. Drawing D101 shows a plan view of the stormwater utilities in the project area, including landscaped and permeable areas. 5.3.2. PERMEABLE CONCRETE Permeable concrete is still a relatively developing field, and there are currently no widely accepted standards. The design for the permeable concrete was developed based on best practices and guidelines from the City of Vancouver, National Ready Mixed Concrete Association, UNH Stormwater Centre, and Flood Testing Labs. Layer depths were determined based on the capacity required to store a 10-year 24-hour duration intensity storm, assuming no infiltration into the subgrade. The final design offers 95.2mm of storage compared to an expected 67.2mm of precipitation. This contingency can help to detain excess rainfall from the adjacent landscaped areas and prevent ponding in extreme events. Detailed calculations are available in Appendix E. 28 Table 9 summarizes the target construction specifications for the permeable concrete, and Figure 14 below illustrates the required layers for construction: Table 9: Permeable Concrete Specifications Specification Requirement 28 Day Compressive Strength 20 MPa Infiltration Rate 8600 mm/hr Void Space 15% Unit Weight 1500 kg/m3 to 2000 kg/m3 Slump 15cm to 18cm Figure 14: Required permeable concrete layers A detailed mix design was considered to be outside of the scope of the project, and the Contractor will be expected to develop a final mix design meeting the above specifications. Due to differences in load response, permeable concrete requires slightly different procedures than conventional concrete. Detailed specifications are provided in the Construction Specifications, but the following key points are identified: • Conventional strength tests are not recommended as compaction is highly variable in cylinder tests for permeable concrete. Instead, a void-density curve should be established for the final mix-design and used for quality assurance during construction • Concrete should be moistened then covered for curing within 20 minutes of initial placement and compaction 29 • A minimum of two panel tests should be conducted on site according to ACI 522.1-13 to establish acceptable ranges for hardened concrete • Three cores will be tested every 75 m3 poured to verify infiltration rate, dimensions, and average hardened density are within values obtained from the test panels in accordance with ASTM C1754 30 6. GREENSPACE The final design includes a multi-purpose green space separating the travel lanes and the cycling path. One of the primary objectives is to encourage use active and sustainable modes of transportation. This new greenspace encourages provides a place for people to gather and enjoy the surrounding landscape, thereby improving the sense of community and health of residents. The landscape architecture design for this area was based on UBC’s sustainability recommendations and past examples of integrated spaces like the Arbutus Greenway. The final greenspace design involves the transplanting the existing maple trees and the planting of 4 new trees at each crossing to further improve on the aesthetic of the corridor. The four new trees to be planted are the Saucer Magnolia, Weeping Cherry, Eastern Redbud, and Red Oak. Additionally, the greenspace features a community garden consisting of several different species of plants at various locations of the median. A summary of the plants utilized in the final design is summarized in the figures below. Figure 15: Hydrangeas (gardeningknowhow.com) Figure 16: Rudbeckia (oscseeds.com) 31 Figure 17: Fountain Grass (gardeningknowhow.com) Figure 18: Mearlow Sage (americanmeadows.com) Figure 19: Tulips (americanmeadows.com) The overall layout and locations of the various components of the greenspace is shown in Figure 20 and 21 below. Figure 20 displays the greenspace plan from Thunderbird Blvd to Eagles Dr, and Figure 21 displays Eagles Dr. to Stadium Rd. Figure 20: Greenspace Plan from Thunderbird Blvd to Eagles Dr. 32 Figure 21: Greenspace Plan from Eagles Dr. to Stadium Rd. Construction requirements for the greenspace include the following: Construction for the greenspace is expected to be done in accordance with the UBC Exterior Improvements Technical Guidelines. In conjunction with current best practices the following key requirements have been identified: • Where possible, existing trees along the current median are expected to be transplanted to their new proposed locations • Newly planted and transplanted trees must be spaced apart according to their mature canopy spread • Erosion control devices such as silt fencing shall be installed to prevent siltation and/or erosion within the tree protection zone • Ensure that soil texture, fertility and drainage at the new planting site by laying composted bark mulch and absorbent topsoil • Soil should be tested prior to installation to ensure acidity and nutrient composition is adequate for the specified plants 33 7. CONSTRUCTION MANAGEMENT This section will provide information regarding construction sequencing, anticipated issues during construction, the construction schedule, and our traffic management plan. 7.1. SEQUENCING To mitigate disruptions to the overall network, construction activity has been sequenced into five sections, each relating to a specific portion of East Mall. The bulk of the work has also been further divided into three phases. Figure 22 details the scope of each specific sequence. For full breakdown of tasks and timelines, refer to Section 7.3. Materials and equipment rentals will be procured at the start of each section. Reviews will be undertaken at the end of each activity, with an audit at project turnover. Figure 22: Construction phases and sequencing 7.2. ANTICIPATED ISSUES A detailed risk assessment was conducted to outline potential setbacks during construction. Table 10 provided below presents several key hazards identified, along with their likelihood of occurrence and impact to the project. A more detailed description of the hazards is also provided in this section. Refer to Appendix H for the risk register in its entirety. Table 10: Risk analysis of construction method Risk Likelihood Impact Design changes Low High On-site incidents Moderate Moderate Interrupting Buried Utilities Low High Traffic Delays Moderate Moderate Damage during tree transplant Moderate Low Design changes Due to continuous stakeholder engagement, there is potential for varying magnitudes of design changes. Unforeseen site conditions might also require change orders during construction. A substantial change could greatly impact the traffic and stormwater analysis, resulting in schedule delays and cost revisions. To mitigate 34 this, site constraints will be clearly communicated to stakeholders and contractors. Our team will also address issues case by case to mitigate design changes. On site incidents This hazard includes both worker and pedestrian accidents on site. Due to the sheer number of days worked, it was deemed a moderately probable occurrence. Impacts would vary depending on the incident. To mitigate this, procedures will be developed with worker safety at the forefront. A daily hazard assessment of the site must be conducted prior to start of work by the supervisor. Routine site inspections will be conducted to ensure WorkSafeBC compliance. Equipment will only be operated by qualified personnel. Adequate signage and fencing will block off public spaces and minimize contact with pedestrians. Interrupting Buried Utilities Due to the limited information regarding buried utilities, there is potential for accidental contact during construction work. Depending on the affected system, the impact can range from moderate to high. Mitigation will require detailed confirmation of pipe depths at areas with substantial earthwork. Amount of excavation has also been optimized in the design. Hand digging will also be done when in proximity to known utility locations. Given the new development proposed at Stadium Road, it is likely utility owners may already have upgrade works planned. In this case, construction could be coordinated so that the upgrade works can happen in conjunction with the road reconstruction to minimize disruption to the community. Traffic Delays Congestion induced by site work will limit access and result in project delays. As such, the East Mall corridor must be able to shoulder a majority of the usual volumes despite construction. Traffic delays were classified as a moderate probability; it will be lowered through the phasing of construction work. Mitigation will consist of the provided Traffic Management Plan and ensuring clear communication with contractors. A bulk of the work is also schedule for the summer with lower volumes. Equipment transport will also occur outside of peak hours when possible. Damage to trees With 47 existing trees requiring uplift, there is a moderate probability of damage during the process. To mitigate this, work will be done in accordance with the Tree Protection Guidelines outlined in the UBC Vancouver Campus Plan Part 3: Design Guidelines (2014). 35 7.3. CONSTRUCTION SCHEDULE Commencing May 3rd, 2021, construction duration was estimated at around nine months, completing on December 16th, 2021. Workdays were taken as Monday to Friday, eight-hour days with statutory holidays off. A schedule summary is provided in Table 11. For a full task breakdown and Gantt chart, refer to Appendix G. Table 11: Key construction dates Activity Start (2021) End (2021) Site Preparation May 3rd May 7th Phase 1 Construction May 10th June 11th Canopy Installation June 14th July 23rd Phase 2 Construction June 14th September 2nd Phase 3 Construction September 2nd December 6th Site Clean-up December 7th December 16th To prevent congestion along East Mall, construction was sectioned into chronological phases. Figure 23 below presents the scope for each phase. Phase one includes the Thunderbird & East Mall intersection upgrades along with roadwork north to Agronomy Road and the pedestrian canopy. Canopy installation will begin mid-June with to minimize roadway disruption. The structure will be complete and inspected by August, allow for immediate use during the fall months. The remaining work along East Mall is divided into two phases. Phase two details the median removal while phase three is dedicated to the new median and greenspace installation. Dividing the work allows traffic to be shifted onto the open lane with capacity for two lane flow. Meeting the usual capacity is essential as phase three will extend into the 2021 winter semester. Temporary parking and traffic control measures will be required. Figure 23: Construction phases 7.4. TRAFFIC MANAGEMENT PLAN Under project classifications set out by the Ministry of Transportation and Infrastructure, the redesign falls under Category 2: moderate impacts on the travelling public and involves some complexity. As such, a full 36 traffic control plan will be required. The figures below provide our management plan for all phases of the project. Temporary signage codes are derived from the BC Traffic Management Manual for Work on Roadways (2016) 7.4.1. PHASE 1 Work zones will be divided into halves of road. The first half will require the closing of the southbound lane. While work is in progress, the adjacent lane will allow for two-way traffic flow, with a total width of 18ft. Traffic flow operators and temporary 15 mph speed limit signs will be posted at appropriate intervals to regulate traffic. Figure 17 details the first half of phase one and the required signage and personal on site. Occurring synchronously with phase 1 is the construction of the pedestrian canopy. To prevent congestion, equipment and operational vehicles will detour down Agronomy and Health Science Mal into the highlighted alleyway. The southern sidewalk of Agronomy will be closed with pedestrian demand relocated to the north. Figure 24: Phase 1 traffic management plan 7.4.2. PHASE 2 Existing median removal headlines phase two which will require work on the southbound lane of East Mall. The wide roadway easily allows for two-way traffic flows on the adjacent lane. Parking will be restricted to meet demands. Adequate signage and pylons will be placed alongside traffic flow operators. Figure 18 below 37 details the phase two configuration. A temporary 15 mph vehicle speed limit will be imposed for pedestrian and worker safety. Figure 25: Phase 2 traffic management plan 7.4.3. PHASE 3 Phase three will require the closing of the northbound lane, with the volume shifted on the finished southbound lane. Similar to phase two, a temporary no parking limit on the southbound lane will be enacted to meet capacity. A 15-mph vehicle speed limited will also be imposed for worker and pedestrian safety. Figure 26: Phase 3 traffic management plan 38 8. COST ESTIMATE The total project is estimated to cost $5,163,449, with an annual operations & maintenance cost of $23,500. A high-level cost breakdown is provided in Table 12. To account for potential uncertainty during construction, a 15% contingency has been assigned to overall costs. For the full detailed Class A Cost Estimate, refer to Appendix F. Unit cost for specific materials has been derived from cost guides from different locales and times. As such, RSMeans Cost Indices were used to normalize costs when applicable. Table 12: Cost Summary Design $179,600 Development $179,600 Construction $3,826,224 General Permitting $28,100 On-Site Personnel $324,000 General Construction $450,000 Site Preparation $690,730 Road Replacement $797,875 Median Installation $131,725 Bike Lanes & Sidewalks $118,025 Stormwater Facilities $100,000 Greenspace $646,650 Permanent Traffic Controls $177,035 Structural $188,084 End of Construction $174,000 Maintenance & Operations $23,500 Contingency (15%) $604,399 Total Cost $4,610,222 PST (7%) $322,716 GST (5%) $230,511 Total Cost + Tax $5,163,449 39 9. SERVICE LIFE MAINTENANCE PLAN This section will outline the potential maintenance concerns associated with the new roadway, canopy, utility, and greenspace upgrades. The items below are only common issues and therefore not exhaustive. Additional issues may arise throughout the lifecycle of the project. 9.1. TRANSPORTATION The main component of the road requiring maintenance is the asphalt. The asphalt road in our final design has a design life of 18 years, after which the road will require repaving. However, to achieve this design life maintaining the driving surface and other roadside upkeep is required. The road maintenance plan consists of the following: Table 13: Maintenance summary and frequency for roadway Activity Maintenance Frequency Crack sealing As required with annual inspections Snow and ice control As required seasonally Pothole patching As required with annual inspections Signage repair As required with annual inspections Pavement marking repair As required with annual inspections Effective road maintenance addresses damage early. Preventive maintenance for the road will be performance based. This approach maximizes the service life and reduces long term costs of the project. 9.2. STRUCTURAL The hot dip galvanized steel canopy has a design life of 70 years. Hot dip galvanized steel structures provide long-term durability. The main concern for the steel canopy is corrosion due to it being located outdoors in a wet climate. That is why a zinc coating was selected since it would be able to provide the proper protection. A Hot Dip Galvanized coating is known for its durability and low maintenance; therefore, the maintenance plan is not overly involved and consists of the following: Table 14: Maintenance frequency and summary for canopy Activity Frequency Inspect and repair damaged welds As required with annual inspections Repair corrosion on the steel by brushing off any rust with a hard plastic bristle brush and repainting with Zingalu spray As required with semi-annual inspections 40 9.3. UTILITIES No new utility mains are installed as part of this project, and so the service life of the existing mains should be unchanged. New catch basins are specified to replace the existing, and the lifespan of a typical precast concrete catch basin including its service lead is estimated to be around 75 years. The on-site utilities do not require any special servicing plans, and the following suggestions are made on the basis of UBC’s Technical Guidelines to preserve utility lifespan: Table 15: Maintenance summary and frequency for utilities Activity Maintenance Frequency CCTV inspection of underground utility services shall be conducted every 5 years to identify potential leaks, root intrusion, among other damage in accordance with UBC Technical Guidelines Section 33 82 01 Once every 5 years Sewers should be flushed in accordance with UBC Technical Guidelines Section 33 01 30.41 Yearly Clear out catch basin sumps and surrounding grate area Twice a year or whenever ponding is observed Vacuum permeable concrete areas with regenerative vacuum sweeper Yearly or whenever ponding is observed 9.4. GREENSPACE The greenspace including its plants and trees all have an indefinite design life and should not require replacement as long proper care and maintenance is provided. Maintenance services are necessary to ensure that the landscape is healthy and looking good. The maintenance plan for the greenspace is the most intensive and consists of the following: Table 16: Maintenance summary and frequency for greenspace Activity Maintenance Frequency Standard lawn care of the land surrounding the garden including lawn mowing and other techniques to maintain the overall appearance of the garden itself Bi-weekly during necessary seasons Watering of all trees and plants along the greenspace Daily Renewing mulch to protect roots and soil moisture Bi-weekly Lawn fertilization and pest control Annually Tree and shrub insect treatments As required with annual inspections Leaf removal and trimming Annually Aeration and over seeding of the grass Annually 41 10.
