UBC Campus and Community Planning approached Roundabout Solutions in September 2015 to develop an intersection layout that improves the interface between vehicles, pedestrians and cyclists while revitalizing the location’s gateway aesthetic. The intersection improvement requires a low impact design that integrates into the existing BC Ministry of Transportation (BCMOT) roadway alignment.   In November 2015, Roundabout Solutions proposed a long term solution that would incorporate an immediate curb and lane improvement project that would demarcate cyclist travel with dedicated lanes, improve line markings to increase driver and pedestrian awareness of cross-traffic pathways, and improve turn storage and overall intersection geometry to improve driving experience. This low impact solution would deliver immediate improvements to the interaction experience by eliminating confusion and risk for all users.  A roundabout design was ruled out due to significant issues with encroachment onto the Pacific Spirit Park and the existing unfavorable horizontal and vertical alignments.  Roundabout Solutions has anticipated future growth of the intersection and has proposed a long term vision of the intersection with future project add-ons for a signalized pedestrian crossing and a pre-timed signalized intersection arrangement. This design add-on meets the BC MOT guidelines for signalized intersection warrants.  A terraced lookout was proposed for the North greenspace of Allard Hall to revitalize the local aesthetic. This 2.5m retaining wall design would leverage the site’s topography to produce a gathering area that would inspire movement to the North Campus area. The retaining wall is constructed from pre-fabricated blocks with granite façade and the 3000 square-foot patio area incorporates a functional and inviting seating area that will improve the gateway aesthetic.  Roundabout Solutions commenced on the detailed design phase of the project in January 2016. The estimated construction cost for the East Mall and NW Marine Drive intersection improvement project is forecasted at $1.0M. The project expected construction complete date is September 2016.  The following report outlines the specific design features of the project as well as the design inputs and estimated costs.

Introduction The East Mall + NW Marine Drive Intersection Improvement Project will revitalize the functionality and aesthetic of a key UBC campus gateway. This project achieves the objectives outlined in the 2014 UBC Transportation Plan [1]:   Prioritizing safe movements at the intersection with improvements to lanes, markings, andsignage. Increasing driver awareness of pedestrians and cyclists with improved intersection featuresand geometry. Improving the gateway aesthetic for students, visitors, and the community at large with a newlyinspired gathering place.The East Mall + NW Marine Drive Intersection Improvement Project scope is divided into two primary areas: 1) The roadway improvement scope includes the pavement refurbishment, crossing and laneimprovements, and the overall geometric improvements for the intersection and approaches.2) The lookout terrace scope includes the new gathering space and accompanying landscapingimprovements that highlight the importance of the gateway.This detailed design was performed by Roundabout Solutions over the first quarter of 2016 and included a series of iterative design steps aimed at refining the vision outlined in the 2015 Preliminary Project Design. Multiple field visits and design workshops have led to the development of a comprehensive scope of work. Analysis of terrace slope stability, traffic performance, and pavement resilience has guided the design of the project.   This report presents an outline of the specific design features of the project followed by an overview of the design inputs considered during the detailed design process.  The detailed project cost estimate has been updated and is also enclosed. The Summary Design Presentation slides are appended to the report along with a set of pertinent design calculations undertaken during the detailed design phase.       Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  6 Figure 1: Birds-eye of East Mall + NW Marine Dr      Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  7 2 Design Features The East Mall + NW Marine Drive Intersection Improvement Project is divided between the transportation (Intersection Scope) and gateway lookout (Lookout Terrace Scope) objectives as illustrated in Figure 2 .  The transportation design improvement includes a revised curb layout to improve storage and turning performance. A new demarcated bike lane and improvements to the location and visibility of the intersection crosswalk will improve cyclist and pedestrian safety. A long term solution to accommodate future growth of vehicle, cyclists, and pedestrians has been adopted into the short term design. If future demands warrant the implementation of a signalized cross walk or a pre-timed signalized intersection, the lighting, controls, and foundations will integrate within the proposed curb and lane layout.   The gateway lookout design integrates seamlessly with the existing greenspace north of the Allard Hall building. The retaining wall is designed to project north from the Allard Hall building giving a 2.5m lookout advantage for users. The lookout patio affords users unparalleled views into the Pacific Spirit Park.   The specific design features of each project area are outlined in this section detail.   Figure 2: Scope of Work Breakdown     Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  8 2.1 Intersection Scope  The objective of the intersection design improvements is to improve the horizontal alignment to improve efficiency and reduce confusion for users with limited interference to the adjacent properties and utilities.   The intersection scope of work is bounded by the private property lines that surround the intersection and include work on both provincial and private roads. Refer to Appendix C for all project drawings Figure 3 - Scope for Phase 2 of Signalized Intersection  2.1.1 Curb, Lane, Stormwater Improvements The curb layout was designed for minimal impact while improving stopping sight distance (SSD) and pedestrian and cyclist safety.    Pedestrian cross-walks and bike lanes  Proposed footprint to fit within existing  Integrate with existing plans for Chancellor Blvd Bike Lane Alignment (Bunt & Associates).  Proposed pavement to match existing elevations   Lane widths of 3.6m and 1.5 were used for car and bicycle use respectively. To ensure the local drainage patterns were preserved and guidelines for the UBC Integrated Stormwater Management Plan (ISMP) the following scope is proposed:  4 additional catch basins  5 catch basin rehabilitations   Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  9 2.1.2 Pavement Rehabilitation The pavement rehabilitation scope considered pavement rehabilitation and pavement construction.  Pavement rehabilitation consists of milling off the top 50mm of existing pavement and applying a new wear-coarse of asphalt.   New pavement area new consists of base courses of gravel, compacted fill, and asphalt.  2.1.3 Future Option – Specialized Crosswalk Consideration has been made to incorporate a future allowance for a signalized crosswalk if future crossing opportunities are restructured by an increase in traffic volumes. The scope includes:  Pedestrian crosswalk signals including foundations, electrical conduit, and poles  Roadway improvements for pavement, curb and gutter  Improved crosswalk signage.  2.1.4 Future Option - Traffic Signals Design considerations have been made when volumes warrant the need to establish signalized control at the intersection:   Installation of traffic control cubical box with a pre-timed signal phasing system  Low voltage power and duct banks.   Installation of traffic signals and accompanying supports.      Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  10 2.2 Lookout Terrace Scope The lookout terrace will be formed as a gravity wall using the proprietary “Recon” retaining wall system incorporating their standard drainage, fencing and wall cross sections. This was chosen because of the versatility of the design, ease of installation and ability to conform to UBC’s visual aesthetic. The Lookout addition provides a Gateway feature consistent with the UBC campus plan and addresses a larger scale community improvement with the creation of an enjoyable public space.  The lookout terrace project limits are bounded by the triangular green space adjacent to East Mall, Iona Drive, and the north face of the Allard Hall building and is shown on Figure 4.  The wall system, patio, and area improvement scope is discussed in further detail below.  2.2.1 Retaining Wall System The retaining wall system serves as the structural support for the terrace patio and extends to the shallow footings supporting the stairway and the upper landing connected to the Allard Hall Gateway building.   The retaining wall will also serve as a Gateway entrance and feature a University of British Columbia sign.  2.2.2 Area Landscaping and Improvements The Lookout landscaping and improvements scope is split into two sections, preservation and rehabilitation. Most of the area encompassing the Lookout will be preserved, which includes mature trees and a monument (west of the Lookout), and a gas access (east of the Lookout). However, as the project commences the majority of the area will require rehabilitation. This includes the introduction of native and edible plants, shrubs, and other simple landscaping elements. Recently planted ceremonial trees will need to be considered, as the trees are in the Lookout’s footprint. This will require the relocation of the trees, which requires a Project Landscape Architect.  Figure 4: Allard Hall Lookout Terrace        Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  11 3 Design Criteria The design of the East Mall + NW Marine Drive Intersection Improvement Project has been developed to meet both the robust requirements of a provincial highway and the long term asset lifespan expected for a university facility. The BCMOT guidelines for highway design were used as the basis for lifespan requirements for the curb, pavement, and line markings.The British Columbia Building Code was used in conjunction with UBC specifications for asset reliability in determining the resilience and design loadings for the lookout structure. 3.1 Intersection Design Criteria  3.1.1 Design Life & Demand A 20-year design life for the pavement and curb components was chosen based on BC MOT standards.  The primary design loading consideration is the Equivalent Single Axle Loadings (ESALs) derived from available traffic count data.  Roundabout Solutions has specified a coloured bike lane treatment resilience in absence of a provincial or campus specific standard. Due to the high volume and variable stopping behavior at the intersection, a non-paint based marking system is specified which must exceed 6 times the expected lifespan of a traditional paint marking (1 year). The design ESAL loading, pavement lifespan and bike lane marking lifespans are illustrated in Table 1.   Table 1: Design Loading - Pavement Criteria Loading/ Lifespan ESAL 3.32M Spot Repairs  (40mm thk patch) 10 years Mill & Hot Mix  Wearing Course 20 years Green Bike Lane Markings 6 years  3.1.2 Transportation Design Manuals  The project’s transportation design basis was established from the BCMOT manuals as outlined in Table 2. Table 2: BCMOT Standards for Transportation Planning BCMOT Document Input Description Electrical and Traffic Engineering Manual (2013) Volumes required for signal warrants Pedestrian Crossing Control Manual for British Columbia (1994) Pedestrian crossing design options and volume warrants for signal controls  Planning and Designing Access to Developments (2009) Project scope planning and governance identification    Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  12 3.2 Lookout Terrace Design Criteria 3.2.1 Design Life & Loading Roundabout Solutions criteria for the design of the Lookout Terrace retaining wall was developed with guidance from the 2012 BC Building Code. Following the above listed guidelines and others listed in Table 5, it was determined that the retaining wall for the lookout terrace would have a design life exceeding 20 years, and would comply with the designated factors of safety for stability listed in table 3. The Peak Ground Acceleration (PGA) used during the design phase was consistent with a 1-in-475-year seismic event.

The design standards were influential in both developing the design criteria and the detailed design attributes of the design drawings.  4.1 Roadway Design Standards Roadway design inputs considered the various jurisdictions present in the project and can be summarized in Table 4.

Table 6: UBC Landscape Design Considerations Landscape Consideration Input Criteria  (VCP Section 3) Architectural Style ‘International Style’ District design area ‘Contemporary’ district Planting area edging width 3m Street-side Trees Maple (Chancellor Boulevard) and ‘Reinforce Forest’     Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  15 5 Technical Considerations The detailed design of the East Mall + NW Marine Drive Intersection Improvement Project required engineering assessments for the transportation, stormwater, and geotechnical systems. Two major engineering challenges were reviewed.  Firstly, the intersection improvements needed to perform over a minimum 20 year lifespan. This required an extensive review of potential growth issues that might impact the intersection. Secondly, an assessment of the interaction between the retaining wall system and existing utilities and roadways was critical due to the close proximity between the intersection and the lookout terrace. This assessment also sought to evaluate the project’s stormwater impact on the downstream system.The assessment tools used as well as the assessment findings are outlined in the following sections.  5.1 Project Assessment Tools Engineering analysis software was used extensively throughout the detailed design of the project. Specific tools related to the transportation, stormwater, and geotechnical assessments are described further below.  5.1.1 Transportation Modelling & Assessment Roundabout Solutions implemented Synchro 6 as the traffic analysis platform to evaluate the intersection performance for both present day and future conditions. A baseline scenario using 2014 traffic count figures was established to develop a do-nothing scenario. Using growth factors (see     Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  16 Table 7) developed in the Preliminary Design phase of this project, future conditions extending out to 2041 were modelled.  Roundabout Solutions evaluated the performance of the intersection using the stochastic features of TrafficSIM simulation. This software provided a visual representation of both live action performance of the intersection as well as visual representations of queue length.  5.1.2 Site Hydrology Analysis Software Roundabout Solutions used QUALHYMO’s Water Balance Model (WBM) to evaluate the post-development impact associated with the Lookout. This online tool rendered a model to evaluate runoff quantities and onsite source controls. WBM evaluated the impact associated with installing impervious paving of the terrace patio and reducing the site’s overall cross slope grade.  5.1.3 Geotechnical Design Software During the design of the Lookout Terrace, the geotechnical design calculations were completed using Microsoft’s Excel program, and by hand. Please see Appendix E – Geotechnical Calculations for a typical example of calculations used for the Geotechnical Design. 5.1.4 CAD Design Software The geometry of the road layout, alignment, and details were designed using AutoCAD Civil 3D 2016.     Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  17 5.2 Traffic Forecasting Assessment The transportation planning analysis was the starting point for the intersection design considerations. Traffic count data for 2013 and 2014 was supplied by the UBC Campus and Community Planning department.  The traffic count data contrasted the volumes between major (Chancellor Blvd and eastbound SW Marine Drive) and the minor (East Mall and southbound SW Marine Drive) routes. The anticipated growth of the vehicular and pedestrian/cyclist traffic was previously estimated by Roundabout Solutions in the 2015 Preliminary Design Report. The governing volume design scenario is presented in Table 7. A major finding of the traffic assessment was the signal warrant volumes for both pre-timed intersection signals and pedestrian signals are not immediately large enough to warrant traffic flow interruption according to BC MOT specifications [3], [4]. This is illustrated using the Warrant 9 Peak Hour Volume graph in  Figure 5 [3]. Using the 1.7% vehicle growth rate, Roundabout Solutions estimates that the traffic volumes will warrant a signalized intersection in the year 2040. Furthermore, using a 2.7% pedestrian and cyclist growth, Roundabout Solutions estimates a specialized crosswalk will be warranted in 2036.  Evaluation of the proposed design layout using a 5-year growth estimate was performed in Syncho 6. The results of the analysis made the following conclusions:  - Short range capacity Utilization: 41% - ICU Level of Service: A - Average Delay: 4.9s - East Mall V/CMAX: 0.31 The Unsignalized Intersection Capacity Analysis is presented in Appendix A and informs Roundabout Solutions’ conclusion that the intersection will exceed BCMOT performance requirements.

A future stormwater management project, ISMP#11, has been identified by UBC and proposes a 1,700m3 detention structure be installed within Chancellor Boulevard to retain a 1:200-year rainfall event [5].  Furthermore, it is understood that restrictions for stormwater infiltration exist due to concerns of slope erosion on the Pacific Spirit Regional Park [6].  Roundabout Solutions has assessed the post development impact of the curb improvement and lookout terrace designs to ensure a) no overland drainage impacts the system and b) adequate source controls are established to reduce stormwater volumes and velocities. The Water Balance Model was used by Roundabout Solutions to assess the project impact. The results are available in Appendix B and can be summarized as the following:   - Point Source Control: Impervious Terrace Paving with 150mm thick sand base.  - Reduction to overland drainage: 18.6% Roundabout Solutions has also incorporated improvements to the roadside catch basins as a site inspection revealed multiple stormwater catch basins are damaged and plugged. Details for the stormwater design can be found in the attached detailed design package.  Figure 7: ISMP Project #11 Prelminary Layout                       Figure 8: Water Ponding on SW Marine Drive - Photo Taken Jan 29 2016         Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  20 5.4 Lookout Geotechnical Assessment Geotechnical design and calculations were based on various design guides. Assumptions of soil characteristics were based on previous campus geotechnical reports. Further site investigation is strongly recommended to verify soil conditions. The design inputs, criteria, and presented assumptions are presented in Table 5 and Table 8.)   Table 8: Geotechnical Design Assumption Inputs Soil Characteristic Assumed Values Primary Soil Layer Sand and Gravel (Trace silt) 0 – 0.9m, compact to stiff, Moisture Contents 18-33% Primary Soil Layer properties ɣ = 18 kN/m3, ɸ = 35°, tanδ = 0.5, c = 0 Secondary Soil Layer Sand, some silt, 0.9m – 2.4 m, compact to dense, Moisture Content 10-33% Ground Water Level (GWL) 2.4 m below surface        Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  21 5.5 Recommended Pre-Construction Assessments  Roundabout Solutions recommends that UBC undertake a 2016 traffic survey and a geotechnical investigation. These additional assessments prior will reduce risk if done prior to construction and are outlined further below.  5.5.1 2016 Traffic Study Update Roundabout Solutions recommends that a 2016 Traffic Count be performed on the intersection to establish a pre-development baseline performance.  A 2016 traffic count should include a qualitative study on pedestrian and cyclist experience through the intersection. This would be accomplished with the following data capture:  - Street interview to canvas pedestrians and cyclists using the intersection with emphasis on user experience.  - Traffic study counts of traffic violations made by pedestrians (jaywalking), cyclists (failure to stop), and cars (failing to yield).  - Reports of near-misses between traffic and pedestrians/ cyclists.  5.5.2 Geotechnical Investigation The Geotechnical design process was completed using assumed values and soil conditions similar to The Acadia and Toronto Roads – Preliminary Geotechnical Report (2015) which was provided to Roundabout Solutions. Roundabout solutions is recommending that a further geotechnical investigation be completed in the area designated for the Lookout Terrace. The purpose of this Geotechnical Investigation would be to provide accurate site specific soil conditions, and more precise input values to be used during the design phase. The British Columbia Building Code: Schedule B, dictates that a Geotechnical Investigation be conducted during the design phase of a retaining wall. A prepared Geotechnical report will be invaluable in ensuring Roundabout Solutions can provide a cost-effective. The Geotechnical Investigation would consist of two (boreholes) on site and would included a prepared report on the findings from the contracted Geotechnical Firm. The anticipated cost $5,000. The borehole drilling can be completed in one day, and the report would require a week to prepare.

Thereby, two important elements need to be reviewed. First, the intersection will need sequencing during construction to help mitigate interruptions to traffic flow through the intersection. Second, a risk assessment is needed to provide a contingency for potential hazardous events that may occur during construction. The construction sequencing and risk assessment are outlined in the flowing sections. 7.1 Construction Sequencing To help mitigate interruptions to traffic during construction, a sequencing plan was developed using MoT’s 1999 Traffic Control Manual for Work on Roadways. Using this manual, a two-phase construction stage sequence was developed to mitigate traffic flow through the work area to provide safety for pedestrians, cyclists, workers, and other road users.  Phase 1: A 21 day closer time will be implemented in the south section of the intersection, see Appendix F Drawing TM1 - Traffic Management Plan Phase 1 for work area and other details.   Phase 2: A 7 day closer time will be implemented in the north section of the intersection, see Appendix F Drawing TM2 - Traffic Management Plan Phase 2 for work area and other details. A traffic control company will be subcontracted to provide traffic management. This will consist of signage, fencing, delineators, message boards, stop guards, and other traffic management tools. 7.2 Risk Assessment A project risk assessment was conducted to reduce the potential impact of a hazardous event. Project activities that provide unknown risk characteristics were tabulated in a matrix.  The cost of the consequence and the probability of occurrence were determined. The option to avoid, mitigate or accept the risk was made followed by a calculation of a reasonable project contingency value. Please refer to Risk Matrix Analysis in the Appendix C for more detail of the risk assessment and contingency basis. The total risk contingency recommended for this project is approximately $82,000 or 7.4% of the total project construction cost. The project cost estimates are prepared using a +/- 30% cost variance which equates to a $300,000 contingency in cost variance considerations.     Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  25 8 Project Schedule Roundabout Solutions has prepared a project schedule timeline. According to the BC MOT manual for development access, the detail plan will be the primary document for road authority approval. Estimates for permit processing time have been included in the overall timeline. The detail project schedule forecasting the implementation date has been prepared in MS Project. The full project schedule is found in Appendix E: Project Schedule. Highlights of the project timeline are as follows:  A detailed design phase for the intersection and lookout has been estimated to occur over a 9-week window  It is expected that a Traffic Impact Assessment (TIA) is required as a permitting deliverable and a 30 day TIA window has been developed into the project timeline  Permitting for BC MOT and UBC Campus Planning is expected to take 30 days once the detailed design package is prepared  A 38 day window for project procurement has been estimated for tendering once the permitting phase of the project is concluded.  Construction is expected to kickoff at the beginning of July 2016 with a 56 day window estimated for the intersection and a 77 day window for the lookout. The intersection would be open for traffic in mid-September 2016 and the lookout would open for users mid-October 2016.  Contingency for project unknowns has been built into the engineering and procurement phases. See the following section on  Activity durations have been developed from past experiences with projects of similar scope and complexity.     Final Design Report – April 2016 EAST MALL + NW MARINE DRIVE INTERSECTION IMPROVEMENT PROJECT  26 9 Cost Estimate The current cost estimate has been prepared using an 80% design complete assumption and available unit rates. This cost estimate will be refined once the design is accepted as “pre-tender”. The estimating methods and cost breakdowns are identified in this section and detailed estimates are provided in the appendix.  9.1 Estimating Methodology Roundabout Solutions has prepared the transportation project scope estimate using the 2013 MOTI Project Cost Estimating Guidelines. The current estimate is based on an 80% design-completeness assumption and implemented the prescribed “Elemental Parametric Estimating Method” as outlined in the guidelines. MOTI unit rates were used as a basis and a 20% (+/-) contingency range is proposed.  The Lookout Terrace cost estimate was prepared using estimated unit rate from precedent projects and past experience with work completed in the UBC area. Assumptions on ground conditions and available materials have been made for the project.  Maintenance cost estimates will be prepared for the final design report using the surface area of landscaped area and newly added fixtures such as lighting and hardware.  9.2 Intersection Cost Impact A summary cost breakdown for the 2016 intersection curb improvement scope of work is presented in Table 8. A detailed cost estimate breakdown is appended to this report and outlines the unit rates, contingency allowance, and the forecasted cost of implementing a signalized intersection in year 2040.

The refurbishment and redesign of intersection presented herein will exceed BC MOT performance requirements and prioritize the safe movement through the intersection with improvements to intersection geometry, signage, and lane control.  This design is a cost efficient solution to manage the present demands of the area. The implementation of protected crosswalks and a signalized intersection is included in the design to accommodate future growth and play a role in the long term solution to traffic management near the University. The Gateway Lookout design will create an aesthetically attractive entrance to the UBC campus’ East Mall. With stunning views facing the Pacific Spirit Regional Park, the lookout can serve as a gathering space for students, which is consistent with the requirements of the UBC campus plan. Overland drainage impacts across the intersection and lookout have been reduced to protect the Pacific Spirit Regional Park.
