This report is to present the detaileddesign regarding the East Mall Redesign Project. Design of each component is to comply withapplicable design guidelines, subjected to the City of Vancouver By-law and relevant City ofVancouver Construction Standard of Specification. Components details are designed to theelement extent, with supplement drawings for illustration.2.0 Key Components and Design CriteriaEast mall redesign target is a 1km roadway from 16th Avenue intersection to agronomy roadintersection. The road comprises five main intersections and 4 roadway sections. The differentrearrangements of each roadway component are aiming to fit into the existing land uses andoptimize the safety, comfortability and traffic conditions. The design key components include:● Roadway Realignment● Stormwater Management● Traffic Management● Traffic Signage & Pavement Marking Rearrangement● Canopy Design at Agronomy Road Intersection● Underground Utility2.1 Roadway RealignmentBased on the existing road right-of-way layout, the road is divided into four designed5sections as listed below:Road Section Length(m)Existing RoadRight-of-WayAverage Width(m)Proposed RoadRight-of-WayAverageWidth(m)Section 1 16th Ave. toStadium Rd300 40 25 (as required)Section 2 Stadium Rd toEagle Drive230 40 42Section 3 Eagle Drive toThunderbird Blvd220 40 42Section 4 Thunderbird Blvdto Agronomy Rd160 25 25Table 1. Summary of Designed Road SectionsEach section has a specific roadway arrangement plan in accordance to its property lines andthe existing street zones. The major adjustment of road alignment happens on road section 1,the proposed design removes the existing road median and narrows the entire roadright-of-way from 40m to 25m in order to maximize the space for the future stadiumneighbourhood and . Though the road gets narrowed, we keep the 2.7m multi-use parking6areas on both sides to support the high demand of the drop-off and pick up activity. As roadsection 1 has Thunderbird stadium on the west side and the UBC baseball field on the eastside, lots of entertaining and social events are held in this area frequently, so this section isclassified as the area of high pedestrian activity (including temporary special events orseasonal), the desirable sidewalk space of 3.0 m is designed on both sides of the road toprovide people with the spacious and comfortable pedestrian through zone to get access tothe sports field. And the new alignment of road section 1 will tie in with road section 2 fromthe stadium road intersection. Different from the existing street zone arrangement, exceptthe south bound of road section 4, all the road sections will replace the existing asphalt bikelane by the rubber bike lane which will be paved above the curb and separated from theparking lanes or car lanes by the curb and green space. This new bike lane is classified as theprotected bike lane with the highest comfortability which is protected from motor vehiclesby curbs and planters. This new design further improves the safety and riding experience ofcyclists as well as the safety of drop-off activities. As for the unchanged road section 4, thebike bollards will be installed to separate the bike lane and the car lane.The road design has 5 main road elements which include car and parking lane, bike lane,sidewalk, green space and curb ramp. The design strictly follows the City of VancouverConstruction Specification, Standard Detail Drawing and Design Manual. The typical crosssection of road section 1 is shown as follows, see Figure 1 for all the road cross sectionviews.7Figure 1. Typical Roadway Cross Section2.1.1 Car and Parking Lanes2.5% slope from curb to crown with 3 layers of material: a) 75mm surface layer: 19mmsuperpave hot-mix asphalt concrete paving. b) 150mm second layer: 19mm minus combinedcrushed granular base. c) 300mm third layer: 75mm minus crushed tailings granularsubbase.2.1.2 Rubber Bike LaneWith min. 2.0 % cross slope from curb to side with 3 layers of material: (a) 12mm surfacelayer: 3-6mm recycled rubber granules. (b) 150mm granular base: 19 minus combinedcrushed granular based. c) 300mm third layer: 75mm minus crushed tailings granularsubbase.82.1.3 Sidewalk1.0% - 3.0% cross slope rising from gutter to the side with two layers of material: (a)100mm Surface layer: CIP hand-formed concrete (min. 32MPa at 28 days) with a 6mm x25mm sawcut joint on the surface. c) 150mm Second layer: 19mm minus combined crushedgranular base. Type B Curb and Gutter are selected for the design.2.1.4 Green SpaceCity approved topsoil products include: on-site topsoil, imported topsoil and manufacturedtopsoil with the min. depth of 450mm is suggested, and the designed depth of the topsoil andthe rock pit for the rain garden area will be specified in Section 2.4.1.1.City approved seed mix shall be applied. Comparing seed with sod, as the root systems ofseed usually grow more efficiently when the grass matures, we choose seeding over soddingturf for the long term quality consideration instead of . In addition, seeding is about 20 timescheaper than sodding.Trees are relocated to assigned locations with 8m - 10m average spacing, 15m^3 soilvolume/tree, and min. 0.3 distance from the back of the curb. The root barriers and the50mm mulch with 0.5m radius coverage will be placed for each of the tree pits.2.1.5 Curb RampApply double curb ramp for intersections and lane curb ramp for laneways with 7.1% ±1.2% ramp slope. Score lines shall be in direction of travel and parallel with crossing withmin. 6 lines and be 150mm apart.92.2 Traffic ManagementThe traffic management design aims to prioritize the travel efficiency of transit, walking, cyclistsover personal vehicles and reduce vehicle speed before intersection and ensure pedestrian safety.2.2.1 Intersection ComponentsOn each intersection, street name signs, PTZ cameras, advance warning signs and illuminatedcrosswalk wings should be provided2.2.2 LED Traffic Signal LightAccording to ITE standard, the traffic signal shall have a light center length of 62mm, 595 ratedinitial lumens, operating over the temperature zone from minus 40 °F to plus 165 °F. The designwill keep the existing four traffic signal lights on the Thunderbird and East Mall intersection butchange the phase time to accommodate future growth traffic volume and improve trafficefficiency.2.2.3 Detector LoopsDetector loops shall be installed in the final base lift of asphalt. Loop junction boxes and stubconduits are to be placed in a manner that the loop tails will not cut through or cross anyspecialty road surface treatments.2.2.4 Pedestrian Controlled Yellow Flash LightA 450mm bi-modal LED display with countdown display pedestrian signal light shall beinstalled on each side of the intersection of Stadium Road, Eagle Drive and East Mall. A yellowpolycarbonate backboard with 75mm border of yellow prismatic retro-reflective sheeting should10be provided on each pedestrian signal. A concrete base is buried on the ground to connectconduits and wires. An aluminum pedestrian use signal will be mounted on the pole which holdsthe LED signal light. There are totally four LED signal lights installed.Figure 2. Pedestrian Controlled Yellow Flash Light2.2.5 Traffic Sign2 speed limit signs, 18 pedestrian cross signs, 1 do not enter sign are installed on the East Mallshown on the plan view.11Figure 3. Pedestrian Cross Sign2.3 Sidewalk CanopyThe proposed canopy structure will be installed along both sides of the sidewalks alongAgronomy Road in between East Mall and Health Science Mall to provide a temporary shelter tokeep the traveling pedestrians from getting wet during the rainy or snowy seasons. Due tosidewalk constraint, canopies on eastbound and westbound are designed with differentdimensions. Dimension of the canopies are as follow:● Westbound - 4.5m x 90m, clear height 2.5m● Eastbound - 8.1m x 46m, clear height 2.5m;12Schematic layout of the canopies is shown in Figure 4 and virtual visuals are shown in Figure 5and Figure 6.Figure 4. Plan Layout of Canopies along Agronomy RoadFigure 5. Westbound Canopy13Figure 6. Eastbound CanopyComponents of the canopy structure are as follow:● Top cover of the canopy is composed of reinforced glazing panels. Glazing productadopted is Pilkington Planar™. Dimension of the glazing is to comply with thedimension of the canopies. These Glazings are frameless. Bolted to the Stainless Steel4-arm spider fitting at four corners, each piece of glazing is structurally secured, whileproviding maximum transparent area. Design Loads will be provided to Pilkington todetermine the strength and thickness of the glazings. Gap between glazings is 5 mm,which is caulked with rubber sealant to ensure the top is integrated and water-leak free.● Structural timber columns are the main support. Columns are spaced 4000mm on the longspan. Typical column is 241mm by 241mm Glulam PLUS. Each column has the bottompre-bolted with 4 bolt holes of 22mm diameter. A vertical rectangular groove of at least500mm from the bottom of column is cut for T-shape knife plate insert. Actual locationof bolt holes and groove should be adjusted to match the geometry of the knife plates.● Wood Struts are anchored to the columns as lateral bracings if necessary.● LVL beams are sized ½ inch by ⅔ inch. Beams are placed along the long span of thecanopy, setting on top of the columns. Beams are secured to the columns with L-anglesteel and bolted.● Wood members are shop fabricated and assembled on-site. Fire-resistant coating isapplied on all wood members.● 200mm aluminum gutters are installed along the long span on both sides of the canopies.Slope of the gutter is 2%. Additional aluminum flashing is attached to the gutter, and14lapped under the glazing in case of water overflowing. PVC pipe is used for gutter drain,and the pipes are anchored along the columns with U-shape plates.Typical cross section view of the canopy on Agronomy Road Westbound is shown in the belowFigure 7.Figure 7. Pedestrian Weather Protection (Westbound) Canopy Section View2.4 Stormwater Management - Utilization of Green SpaceDepending on each green section’s width and the availability of storm mains underneath, one oftwo different stormwater management plans is implemented. The two plans include tree plantingand rain garden.A rain garden does not require underdrain and will be used in the wider green15spaces to capture enough surface runoffs. While on some sections with much narrower greenareas less than 1m wide, planting trees is a good choice.2.4.1 Tree plantingTree planting is implemented in the 1m or less than 1m wide green spaces, which are listed below. Thenumber of trees for each section is calculated based on the section length and specified tree spacing.Table 2.

Rain gardens are designedto mimic the natural water cycle. Rainwater is soaked into the soil and then rechargesgroundwater for eventual uptake and use by plants. Therefore, no undertrain or external pipeconnections are required. Other design factors such as the garden shape and size, soil mix andlocation are considered.Proposed rain garden areas vary in different widths from 1.2m to 5.64m, depending on wherethey are located along East Mall. The following table 3 specifies key components of theproposed rain gardens at each road section including rain garden width, topsoil depth, rockpitdimensions and other relevant parameters. All rain gardens are designed to effectively capturerainfall runoff from impervious areas such as the sidewalk and rubber bike lanes. Please note thateach rain garden also consists of 0.2-0.3m gravel transition buffer width on both sides to separateit from adjacent the sidewalk and bike lane.Table 3: Summary of Rain Garden Areas with Key Design ComponentsRoad SectionTotallength(m)Raingardenwidth (m)Topsoildepth(m)Rockpitwidth (m)Rockpitdepth(m)16th AVE.

Inurban areas, overland flow can accumulate over rooftops, driveways and sidewalks, which cancause damages due to flooding and water ponding within settlement. In order to minimize thesepotential impacts, excess runoff needs to be properly and efficiently discharged into the stormsystem. In Figure 8 below, existing storm mains are shown in bright green lines, which willremain in the system. However, due to the road re- alignments, there are adjustments to be madeon locations of manholes & catch basins. The figure below shows approximate new locations ofmanholes in black and catch basins in purple. Elevations of each manhole are obtained todetermine the overflow direction through Google Earth data. Elevation is the highest at M11( at96m) and lowest at M1 ( at 86m), which determines the runoff flows towards M1. As per City ofVancouver Engineering Design Manual, the catch basin connection leader shall be no more than30m. The exact distance between catch basin and manhole can be found in the plan views of theroad section in Appendix A. The cross-section views of the manhole and catch basin are shownbelow in Figure 9 & Figure 10.Figure 8. UBC Utility Map along East Mall with manholes and proposed catch basins19Figure 9. Cross-section View of a Manhole on Road Surface20Figure 10. Cross-section View of a Catch Basin2.5 UtilityFor underground utility, MLH has followed the UBC Technical Guidelines. Due to the lack ofaccurate locations of the underground pipelines, Utility Master Map 2019 and UndergroundUtilities within UBC are referred. Most of the pipelines will remain unchanged based on the factthat these underground utilities are located under sidewalks, which would not affect constructionof roadways. On the east side of East Mall, a 500 mm water main and a 250 mm storm sewer islocated below our new sidewalk .For the west side of the East Mall, the water supply pipes and storm sewer shall be located thesame as the east side of East Mall. Also, the electrical line is located at 650mm deep. The naturalgas mains are buried 200mm deeper than its origin place for safety purpose and ease formaintenance.3.0 Design Criteria & Technical Consideration3.1 Roadway Design CriteriaFor the roadway design, pavement design influences the roadway overall lifespan,maintenance requirements, driveability. The pavement shall strictly follow the design21criteria outlined by City of Vancouver.As the project is to realign the existing roadway, the pavement follows the original pavementdesign as well as the City of Vancouver Construction Specification. Pavement componentthicknesses are equal or greater than the requirements of Local/Residential (Light Duty)Streets and Lanes as shown in Table 4. The design life for the East Mall roadway is 30years.Table 4. Asphalt Pavement Structures - Local/Residential (Light Duty) Streets and Lanes(Source from City of Vancouver Design Manual Table 8-21)Pavement Layers ThicknessAC Surface Course 35mmAC Lower Course 40mmGranular Base 150mmGranular Sub Base 300mm223.2 Traffic Design Criteria3.2.1 Speed ControlTo determine the speed limit for vehicles, criteria including delay ratio and pedestrian safetyaverage travel time for each vehicle should be considered. Because the maximum speed limit inBritish Columbia is 50km/hr, the analysis will mainly focus on 40km/hr and 50km/hr.By considering the criteria discussed above, a 50km/hr speed limit is applied throughout the EastMall Road, and bumpers are applied 50m away from each intersection to help ensure pedestriancrossing safety.3.2.2 Traffic Signal PhasesThe traffic control of Thunderbird and East Mall intersection will be signal control and the otherintersection will be pedestrian push button yellow flash light control.The signal phase time is optimized for travel efficiency based on a model result on Synchro.Morning Peak hour:The actuated control type is applied to the intersection in the morning peak hour.● Vehicle Green time:○ Left turn at Westbound along Thunderbird Road: 4s○ Westbound(Thunderbird Road): 25s○ Eastbound(Thunderbird Road): 17s, 25s for call with no left turn at oppositedirection○ Northbound & SouthBound(East Mall): 27s23● Pedestrian Green time:○ Westbound & Eastbound north side: 17s○ Westbound & Eastbound south side: 25s○ Northbound & Eastbound: 27sAfternoon peak hour:The actuated signal control is applied to the intersection in the afternoon peak hour.● Vehicle Green time:○ Left turn at Westbound along Thunderbird Road: 11s○ Westbound(Thunderbird Road): 32s○ Eastbound(Thunderbird Road): 17s, 20s for call with no left turn at oppositedirection○ Northbound & SouthBound(East Mall): 20s● Pedestrian Green time:○ Westbound & Eastbound north side: 17s○ Westbound & Eastbound south side: 32s○ Northbound & Eastbound: 20sRegular hours:The Signal control type is applied to the intersection in the morning peak hour.● Vehicle Green time:○ Left turn at Westbound along Thunderbird Road: 6s○ Westbound(Thunderbird Road): 16s○ Eastbound(Thunderbird Road): 26s○ Northbound & SouthBound(East Mall): 16s24● Pedestrian Green time:○ Westbound & Eastbound north side: 17s○ Westbound & Eastbound south side: 35s○ Northbound & Eastbound: 27sThe traffic and pedestrian volume will grow by 7.76% in ten years. The change will not affectany traffic design applied now.3.2.3 Traffic and Pedestrian Volume AnalysisIn this report, the traffic and pedestrian volume analysis will only focus on the future ten yearsand the growth rate will be 0.75% per year according to UBC SEEDS engineer’s suggestion.3.3 Canopy Design CriteriaDesign of canopy structure is to conform with applicable design guidelines.3.3.1 Design LoadDesign load complies with BC Building Code 2018 (BCBC2018) Division B, Section 4.1.3 andSection 4.1.6. As the canopies are exterior, with no other items expected to sit on top of thestructure, they are considered only subjected to rain load, snow load and wind load. Sectionstatement is shown in Figure 11 below.25Figure 11. BCBC 2018 Division B Section 4.1.6.2According to Section 4.1.6.2, the specified weather load associated with snow and rain isderived, and design factored stress is calculated to be 0.196 kPa. This is the stress incurred by 1in 50 years snow precipitation in Vancouver. For canopy structure capacity, LVL beam bendingcapacity dominates. While the shear force from design load is derived to be 0.784 kNm, LVLbeam capacity is 18.13 kNm, giving a factor of safety of 23. In the case of extreme heavysnowfall, the structure can resist an amount equivalent to consecutive 20 days of snowaccumulation. Given that snow melts and is directed out from the gutter, this extreme scenariocan barely happen.263.3.2 Structural ElementsThe following design guidelines provide basis for element material and dimension selection:● Design of wood members conforms with BCBC 2018 Division B, Section 4.3.1,CSA-O86, “Engineering Design in Wood” and CSA-0177, “Qualification Code forManufacturers of Structural Glued-Laminated Timber”.● Design of steel connections conforms with CSA-S16 “Design of Steel Structure”.● Design of gutter conforms with CAN/CSA S157/S157.1, “Strength Design inAluminum/Commentary on CSA S157-05, Strength Design in Aluminum”.● Design of glazing panels conforms with CAN/CGSB12.20-M, “Structural Design ofGlass for Buildings”.3.4 Storm Management Design Criteria3.4.1 Tree plantingTree planting is used on most of the narrower green spaces in this project, of which width usuallyranges from 1m to 3m. A complete guidance on Street Tree is provided by the City of Vancouver.A few key design requirements and constraints in the guidance are extracted from City ofVancouver Street Tree Guidelines Year 2011 revision:● Tree size selected: Small or Columnar ( Global Maple, Eastern Redbud, ColumnarNorway Maple,etc…)● Spacing: 6-10m● Constraints: minimum distance 1.8m away from driveways, minimum 1.5m away fromelectrical trolley poles273.4.2 Rain garden designDesign of the rain garden is to conform with applicable design guidelines.Simplified rainfall capture method was used to calculate total capture volume by each raingarden.A volumetric reduction criteria of 72% of a 2-year, 24-hour rainfall event was applied todetermine total rainfall in mm. Based on the current IDF curve shown below, a 2-year 24 hourrainfall event has a PPT of 54.41 mm. Therefore the design uses a total rainfall of 39.18mm toestimate input volume for each rain garden. The captured volume, which is designed to be largerthan the input volume, includes evaporation volume, infiltration volume, topsoil volume androckpit captured volume. The evaporation rate and infiltration rate are set at 1mm/hour and1.5mm/ day as per City of Vancouver Engineering Design manual. Detail calculations areprovided in the Appendix.Figure 12. IDF Curve at Vancouver UBC283.4.3 Road Source Control3.4.3.1 Catch basin designThe design of Catch basin complies with City of Vancouver Engineering Design Manual Section5.4.4.Table 5. Catch Basin Catchment Areas and SpacingBased on the requirements provided in the Table 5 above, the number of catchment between twoconsecutive manholes can be calculated by dividing the road area by preferred catchment area.The following Table 6 provides the number of catch basins required between manholes.29Table 6.

A simplified workflow is illustrated below.Figure 14. General Workflow of Road ConstructionThe East Mall project has been divided into 4 sections as mentioned, the designed roadway.willbe constructed section by section, Prior to excavation, the site shall be cleared and surveyed bythe designated surveyors, the proposed storm drain inlets, manholes, centerline of the34right-of-way, face of curbing, elevations etc. shall be staked out by field markers. With thepermission from the owner, the contractor shall move in their equipment and set the materialstockpiles at the designated location (See Appendix A). The excavation will take place after theasphalt cold milling, the roadway excavation activities include the removal of the roadway,granular base and subbase until the proposed subgrade depth is reached. The relocation of thestorm drain system shall be completed and backfilled during the excavation phase. Contractorshall design the temporary detour plan to maintain the traffic during the excavation phase. Whenthe proposed subgrade depth is reached, the 150mm thick 19mm minus crushed granular baseand 300mm thick 75mm minus crushed granular sub base shall be placed to where the existingroadway gets removed with the proper grading and compaction application. The traffic can beallowed to enter the paved areas immediately after the last rolling of the base course.The pavement removal of the curb side will take place after the greenspace removal, utilityrelocation. The removal activity involves sawcutting the existing edge of pavement on both sidesof the road, removing the entire existing concrete curb and gutter, concrete pavement surface andthe granular base material, Placing 150mm thick 19mm minus crushed granular base and 100mmthick concrete pavement to the designed location.the installation of Type B curb and gutter insideof the edge of the surface course and tie-in the curb surface with the road surface. The existingrain leaders which are affected or damaged by the construction will be replaced and extendedthrough the face of the curb. Design depth of topsoil, rockpits will be placed at the designatedspots, the water valves/meters elevation and location might be adjusted based on the newlyinstalled topsoil. Trees shall be replanted at designated locations, All topsoil areas and tree pit35areas shall be seeded and mulched. In the end, tie in the concrete driveways with the asphaltroadway.5.2 Site SetupProject Boundary is the East Mall segment between Agronomy Road and West 16th Avenue.Fencing will be set along the boundary line. The orphan land between Stadium Road and West16th Avenue can be deployed for construction preparation use and locate temporary site huts,material laydown areas, material and equipment storage areas and site vehicle parking. Landdeployment will be negotiated with the Ministry of Transportation and Infrastructure.Figure 15. Designated land deployed for site preparation36Entrance to the site will be at the roundabout at West 16th Avenue. Heavy vehicles coming from West16th Avenue shall follow the roundabout and enter East Mall. Traffic control is to be implemented at theintersection to direct normal vehicles. Traffic control crews are to be at the four entrances of theroundabout to provide stop signals to normal vehicles whenever site vehicles are incoming.5.3 Anticipated IssuesThe following issues associated with construction are considered and solutions are proposedaccordingly.● Noise Control: As scope of the construction is in proximity with many sports fields andcommunities along East Mall, construction noise will inevitably affect neighbors.According to City of Vancouver Noise Control By-law 6555, street construction time islimited between 7:00 a.m. to 8:00 p.m. on weekdays, and between 10:00 a.m. to 8:00p.m. on weekends, including holidays. In this project, construction time will follow theCity Bylaw since surrounding areas are mostly sports fields and users are less susceptibleto noise. For the East Mall Segment between Logan Ln. to Agronomy Road, where officebuildings and residence are more dense, notification of construction noise will be given tobuilding users one week ahead. As street construction noise mainly derives fromoperation of heavy machines, noise control is only needed during heavy machineoperation. Wherever a heavy machine is in operation, temporary noise barrier walls willbe set by the site boundary to mitigate construction noise.● Dust Control: Similar to noise control, wherever dust spread is to occur, notification willbe given to surrounding building users one week ahead. Dust Barrier Zipwall should37encase the area with heavy dust, and industrial dust collectors will be provided tominimize dust spread.● Traffic Detour: East Mall segment subjected to construction connects Agronomy Roadand W 16th Avenue. Vehicles intending to travel across should be rerouted to WestBrookMall. During the construction phase, traffic control is to be implemented at the twoentrances to the East Mall segment. Temporary fence gate will be set. Given that theroundabout at W 16 Avenue and East Mall intersection has a large traffic flow,construction caution, speed control signages and reroute billboard are set at the entranceof the roundabout to notify drivers. Traffic control crews are to be at the entrances of theroundabout to guide vehicles.6.0 Cost EstimateThe cost estimation encompasses the construction of the East Mall redesign on the East Mall inbetween Agronomy Rd. and W. 16th Avenue. The total cost of the project is $11,432,982including 15% contingency (see Table 10), with details outlined in Appendix C: Cost Estimation.This estimate was determined by precedent examples of similar projects, permitting regulationsby law of British Columbia, as well as RSMeans data.East Mall Redesign Cost EstimationMaterial Cost ($) Labour Cost ($) Equipment Cost ($) Incidental Costs ($)8956837.584 636160 273814.48 74911.4128338Total Cost + 15% Contingency ($) 11432982Table 11. East Mall Cost Estimation7.0 ScheduleThe project starts from May 1st, 2021 as required, and ends on Aug 22nd when the last task ofEast Mall construction, painting and signage installation finishes, which lasts 114 days. Projectschedule is divided into three parts: intersection, roadway and sidewalk, since their tasks aremostly independent.As for the intersection, only canopies will be installed there, and the installation is splitted to 6small tasks with one day duration for each of the tasks. A detailed schedule is shown in thefigure below, and the arrows between tasks represent the dependent relationship. The totalduration for this part is 5 days.Figure 16. Intersection Construction Schedule39The duration of the roadway is the longest among the three. Starting with setting out, the part has20 tasks and most of them take around a week. The total duration is 114 days.Figure 17. Roadway Construction ScheduleThe construction of the sidewalk starts after the asphalt milling finishes, and ends when theplanting completes. The total duration is 40 days.Figure 18. Sidewalk Construction Schedule408.0 Maintenance PlanThe road maintenance plan of the East Mall redesign project could be split into 3 categories,namely, routine, periodic, and emergency (see, Table 11). The routine maintenance mainlyfocuses on the daily inspection of the pavement, gutter, sodding conditions,intersection canopydesign, and drainage, etc. Moreover, the routine maintenance activities require both labour andequipment to provide works and adequate quality under cost-effective manners. The result of thismaintenance will be reported weekly, and then analyzed for monthly periodic roadway andintersection maintenance. Whereas the emergency maintenance basically comprises works torestore the sections and related facilities to the normal operating conditions after damages.Table 12. Typical Types of Maintenance8.1 Road Maintenance Quality ControlThe maintenance quality of the East Mall road section depends on the well-ogranizatedsupervision. The supervising department of MHL is responsible for maintenance of road androad facilities for the East Mall redesigned section, implement the maintenance plan, andsupervise the controlled quality of the progress. The maintenance costs should be reimbursedaccording to the actual implemented maintenance cost estimation. Besides, the government and41regulatory authorities of East Mall should carry out a policy of road improvement to reducepotential damage that could happen on the East Mall redesigned project.8.2 Canopy Intersection Maintenance Quality ControlThe main maintenance focuses of the intersection design are the canopy and greeninfrastructures. It requires the same well-organized supervision from the regulatory authoritiesand the MHL company. The maintenance plan shall include the daily routine check towards thewooden frame and glass cover of the canopy and the green infrastructures along the canopy.Also, the routine maintenance plan should be reported and analyzed for the periodic maintenanceof the design, like repairing of the wooden frame, replantation of the green infrastructures, andrecoating of the frame structures. As for emergency cases, the intersection shall be locked downfor safety reasons, and apply maintenance plans corresponding to the site situation.42ReferenceCity of Vancouver Standard Detail Drawings.
