Mount Sinai Hospital

Phase 3 Redevelopment

Phase 3A represents a major renewal of the hospital's main site. HH Angus was engaged to provide mechanical and electrical engineering for the Renew Sinai redevelopment.

HH Angus worked with the Hospital, Stantec Architecture and other consultants to develop the Functional Program and Blocks Schematics for Ministry of Health and Long-term Care [MOHLTC) stages 2 and 3.1 submissions.

As part of our scope, we were involved in the investigation of existing infrastructure and systems. The age of the existing facility, together with previous renovations and multiple facility architects and consultants provided a challenge in obtaining a complete set of existing design conditions. We were provided with drawings in various forms (eg: PDFs. scanned hand-drawn images, AutoCAD and part plans), ranging from the original build to the most current renovation projects. We translated the relevant information into AutoCAD and, in with numerous site investigations, assembled a comprehensive set of record drawings detailing the existing systems and functions.

The scope of the project included a new Surgery Department, renovated and expanded Emergency Department, Critical Care, Medical Device Reprocessing Department, Integrated Practice Unit, Ambulatory, and labs, as well as miscellaneous relocates and decants.

Some of the key challenges of this project included reworking the major mechanical and electrical infrastructure to upgrade systems to current standards, and the integration of disparate systems with existing facilities.

Extensive renovations were implemented. To address the challenges of implementing new infrastructure, HH Angus provided extensive background information and on-site investigation to mitigate risks to the Hospital.

Minimizing disruption to hospital services was of paramount concern in scheduling the renovations. To ensure continued hospital operations, our design solution included planned sequential shutdowns minimized inconvenience to staff, patients and visitors.

Under a standing offer with Mount Sinai, we served as Mechanical and Electrical Engineers of Record and were involved in a variety of projects for Phase 3, including: peer review, fluoroscopy unit. Maternity Clinic renovation, Mouse MRI Lab, Biorepository Lab, Roth Lab, Bremner Lab, Distributed Antenna Systems, lobby upgrade, art gallery/ security/office renovations, and IMIT Planning for Phase 3 Redevelopment and renovations to multiple departments.

Waterfront East LRT - Union Station and Queens Quay Link

The existing streetcar service begins underground at Union Station, extends south under Bay Street towards Queens Quay Station, and continues west under Queens Quay before surfacing at the portal just west of Harbour Square. The expansion will include for a new portal on Queens Quay West, between Bay and Yonge Streets, to allow for service expansion eastward along the surface of Queens Quay West.

HH Angus was engaged to provide mechanical and electrical consulting services for Preliminary Design Engineering for the Waterfront East LRT project. The work includes a Baseline Design (~ 30% design completion), a Class 3 AACE Construction Cost Estimate, and Level 3 project delivery schedule. This is to accommodate the growth and future passenger volume as part of Toronto’s waterfront revitalization project for the expansion of the existing Union and Queens Quay LRT Stations, and a new running tunnel and portal. 

The upgrade will expand on the single track Union Streetcar Loop with a split unloading and boarding platform to become a side-platform station, with each platform capable of accommodating two vehicles simultaneously. An additional by-pass track with special trackwork on the outside of the passenger boarding/unloading track will also be accommodated within the station.

The existing side platform at the Queens Quay station will also be upgraded to accommodate two vehicles simultaneously boarding/unloading at each platform. In addition, the station will provide access to the Jack Layton Ferry Terminal and Toronto’s downtown underground PATH network.

The tunnel ventilation solution—providing at-grade ventilation shafts within a land-locked congested downtown area—required a thorough understanding of various design criteria, as well as meticulous coordination with Architectural, Structural and Civil Utilities disciplines. The final design would entail further computational design analysis beyond the scope of this project in order to address a design variance.

For the overhead catenary system, the team drew on involvement with previous projects (where we were not the designer of said system) to adapt and provide a tailored solution for the unique project requirement of traction power delivery within stations, tunnels, portals, above-grade and transitions in between, working closely with Civil Trackway and Structural disciplines.

Innisfil Health Partners 

Rizzardo Health & Wellness Centre

"[This is] a building designed with an aim of having the highest health standards, engaging the community, and being flexible to meet changing needs." *

The community health hub, an outreach of Royal Victoria Hospital (RVH) in Barrie, serves the towns of Innisfil and northern Bradford/West Gwillimbury. Among its many offerings are blood services, pharmacy, walk-in clinic, radiology, dental clinic, café/community kitchen, interactive kitchen, doctors’ offices, mental health services, physiotherapy, etc. HH Angus provided M&E and ICAT services to the base building and site, along with full tenant fitout.

Flexible design

The Rizzardo Health Centre was designed with flexibility in mind, to allow its services and spaces to adapt to evolving community care needs.

Protecting client interests

One of the challenges of this project was a change in procurement method during the execution of the work, from stipulated sum to design build. Part of our value to the client in this situation was in protecting them from added costs.

Ontario Gaming GTA Limited Partnership 

Great Blue Heron Casino

The Great Blue Heron Casino is located on Scugog Island, northeast of Toronto. HH Angus' scope for this project included electrical engineering, security and telecommunications consulting, and lighting design.

The first phase of the project featured a 20,000 ft2 expansion of the building to house gaming machines and tables, VIP rooms, bar and lounge, washrooms, offices, kitchen and service spaces.

HH Angus designed a new feeder, connected to the existing primary service, and full distribution throughout the expanded building and new outdoor generator. Telecommunications distribution required the addition of a new room to service gaming, corporate and security functions. The existing main telecom distribution room was expanded to support new networking and server equipment. In addition to horizontal distribution, new fiber and copper backbones, and incoming fiber service from Bell, was required to service the expansion. Upgraded and expanded surveillance and access control systems service the new gaming area.

The second phase saw renovation of the existing gaming floor and bar, buffet service and seating areas. The gaming area was completely reorganized for electronic games and a new Play Smart area. The front entrance also received a face-lift and new lighting. Phase 2 leveraged the earlier expansion of the main distribution room and upgrade for telecom distribution, and expanded on the security systems upgrade. As well, it included for a new 4 storey, 116 room hotel and connecting walkway, which required a second high voltage transformer in the existing substation to support the hotel operations.

Four telecommunication rooms were added, along with fiber and copper backbone connectivity. Additional surveillance and access control were included in the hotel scope. Phase 3 is still ahead.

Among the challenges of this project was an accelerated schedule for both design and construction. One solution was to develop strategies to save time on the design side and push the coordination into the construction phase.
