The Ottawa Hospital General Campus (Ottawa, ON)


Castleglenn Consultants was retained to determine the traffic impacts and the parking requirements associated with the major expansions of The Ottawa Hospital facilities including:

  • the Ottawa Regional Cancer Centre;
  • the Critical Care Tower;
  • the Eye Institute;
  • the Regional Lab;
  • the Ottawa Hospital Research Institute (OHRI);
  • the Ottawa Regional Cancer Centre shell;
  • the Children’s Hospital of Eastern Ontario (CHEO) Maternal New-born Centre; and
  • the CHEO expanded operating suites.

The work involved assessing traffic circulation patterns associated with the proposed expansion of the General Campus and undertaking intersection capacity analysis of existing and forecast traffic volumes using simulation techniques that included SynchroTM traffic simulation. The analysis led to the recommendation of an alternative access configuration and parking layout that maintained the number of parking stalls and led to a more efficient on-site traffic circulation.

This Transportation Study assumed the advent of the Alta Vista Transportation Corridor (AVTC).  The Phase I portion of the AVTC will ultimately connect Riverside Drive through to the OHSC Ring Road at a point mid-way between CHEO and the OHSC by way of a 2-lane collector roadway that would also provide a direct connection to the Transitway corridor which runs parallel to, and east of Riverside Drive.  A diversion analysis of existing traffic patterns indicated that the facility, by the end of the 2014 horizon year, could see the diversion of approximately 650vph in the peak direction away from Smyth Road.

Subsequent to completing a Transportation and Traffic Evaluation Study of the Ottawa Health Sciences Centre (OHSC) site, Castleglenn Consultants was retained by the Ottawa General Hospital to complete the detailed design of improvements warranted to the Main Hospital Entrance including widening of a major 4-lane arterial roadway.

Castleglenn was involved in all phases of the design process beginning at the conceptual design phase to obtaining approvals, undertaking detailed design and final preparation of tender documents.

As part of the design process Castleglenn was required to:

  • liaise with utility companies;
  • produce construction cost estimates;
  • obtain design approvals from the City of Ottawa;
  • prepare plan and profile drawings for the roadway widening and access modifications;
  • recommend a pavement structure for the road widening;
  • develop a pavement striping and signage plan;
  • coordinate the road widening/access improvement project with the City of Ottawa as part of a overall rehabilitation of a 3 km section of Smyth Road;
  • prepared tender documents including drawing, construction specifications and quantity estimates;
  • attend design review and pretender meetings; and
  • liaise with project contractor.
