TTC McNicolle Bus Garage- BIM Implementation and Architectural Drawings

weBIM was engaged in the architectural scope for TTC McNicoll Bus Garage project. As a part of the contractual obligation, Stratsman Architects in collaboration with Eastern-Budcon construction intended to use BIM tools for the project. Use of Revit Models was ensured during the construction to deliver as-built drawings along with the integration of IBM Maximo for the TTC project.

Business Challenges

  • Existing Garages were operating at over-capacity
  • New bus garage required within five years to accommodate increased ridership
  • Some buses serving east-end routes are stored and maintained in the west-end garage
  • Extra deadhead time (travel when buses are not in service) adds unwanted wear and tear on buses, shortening bus lifespan and increasing operating costs
  • Not feasible to expand existing facilities and insufficient capacity

Solution Provided

 The BIM implementation was completed in 2 phases:

Phase1: Building Information Model setup – This phase involved developing and auditing documents and methodology for TTC projects.

  • Revit Modeling Strategy
  • SAI BIM Standards – family content, annotation tags & other required elements
  • Review and interpreted the BIM Execution Plan (BXP)
  • Project model setup procedure for efficient output
  • Develop Construction Documentation process using Revit

Phase 2 – Architectural Drawings- weBIM assisted the organization in Floor Plans, elevation, sections, wall section and schedules and details.

  • Attend periodic project coordination meetings at SAI/Morrison Hershfield office
  • Develop Architectural Revit models in 2017 format
  • Make changes in model and drawings as instructed by SAI project Manager
  • Sheet setup for CD drawing set as per drawing list provided
  • Model coordination with other disciplines

BIM Use Analysis

TTC McNicoll Bus Garage_weBIM Projects_5The following BIM uses were pursued during the design and construction stages of this project:

  • Existing Conditions Modeling
  • Design Authoring and Review
    • Design Authoring
    • Design Reviews
    • Model Coordination
    • Visualization/Renderings
  • Constructability Review
  • Record Modeling

The following BIM uses were investigated during the Construction Operations Building Information Exchange (COBIE) planning process:

  • Engineering Analysis
  • Building Systems Analysis
  • Asset Management
  • Space Management and Tracking
  • Maintenance Scheduling
  • Disaster Planning

  • Less Rework and Duplication – BIM Model allowed each discipline to annotate and connect its intelligence to the project. The database aided such steps as the number and size of windows for quantity takeoffs that were updated automatically as the model evolved. As a result, there was a significant saving in labor and cost.
  • Maintain Control- The connection to the version history of the model’s evolution helped to avoid disastrous disappearances or corruption of files
  • Improved Collaboration- Sharing and collaborating with BIM models was easier than with paper-based drawing sets using Navisworks. Review and markup steps ensured that everyone had had the input on the evolution of the design and that they were all ready to execute when the concept is finalized.
  • Reduced Fragmentation– By pulling all the project’s documents into a single view, BIM-enabled teams to collaborate and communicate more effectively.
