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.

The Co-operators

Guelph Headquarters

The Co-operators’ Headquarters in Guelph, Ontario has been certified a 'Zero Carbon Building' by the Canada Green Building Council. The project is also targeting LEED Gold and WELL Platinum.

The renovation project covers three floors totalling 226,000 ft2, and includes a data centre, cafeteria, fitness centre, conference rooms, and three-storey open atrium. HH Angus provided mechanical and electrical consulting engineering, as well as IMIT and lighting design.

The building features an all-electric design to eliminate direct carbon emissions from any on-site source. This means that the company did not need to undertake any retrofits or decarbonization plans to achieve net zero targets. The building has been designed to be highly energy-efficient and to minimize indirect annual carbon emissions from electricity.

Any remaining emissions will be offset through high-quality carbon offsets or carbon-free renewable energy sources. The construction process was also meaningfully reduced, offsetting “embodied carbon” emissions resulting from the manufacture, transportation, and disposal of all building materials.

The Canada Green Building Council has identified the building sector as Canada’s third-largest emitter of greenhouse gases (GHG). Presently, residential, commercial, and institutional buildings are responsible for 17% of Canada’s GHG emissions, and this figure approaches 30% when building materials and construction processes are taken into account.

Despite an aggressive construction schedule, the project overcame the challenges of integrating an all-electric design and achieving Zero Carbon Building certification. It also intended to surpass goals for energy and GHG savings beyond the Ontario Building Code’s all-electric baseline and heating load reduction minimum for new builds. The building features a rooftop solar array and a high-efficiency water source, showcasing innovative approaches to sustainable design.

The building’s low-impact features include:

Energy and GHG savings 40% greater than the Ontario Building Code’s all-electric baseline
60% reduced heating load, surpassing the minimum code requirement for new office builds requirement for new office builds
A 282 kW rooftop solar array that is expected to produce ~9% of the building’s annual total energy
Automatic window tinting to reduce glare and save energy
A highly-insulated and airtight envelope to conserve energy
High-efficiency water source technology to recover and redistribute heat throughout the building
LED lighting equipped with occupancy and daylight harvesting sensors that turn on only when needed

Confidential Client

BIM Laser Scanning

HH Angus was engaged to create a 3D Revit model (LOD 300), accurate to reality, of the existing structure and visible HVAC, plumbing and electrical infrastructure. This model was delivered to the client for their use in 3D coordination of their high voltage switchgear replacement project.

The 17,000 ft2 area was scanned using a Faro S70 Laser scanner, with the scans subsequently registered using Faro Scene software to create point clouds. Point clouds were then processed in Edgewise modeling software and used to automatically extract and model walls, structure, piping, conduit and ducts, before being imported into Revit. This efficient process resulted in a very significant 60% reduction in modeling time. The remaining MEP infrastructure was modeled in Revit, with special attention paid to the location of the entry and leave points within rooms for all MEP infrastructure, in response to the client’s requirement.

One of the challenges of the project was the lack of easily accessible data required to create the Revit model. Recap pro or Faro Scene software is needed to review the point clouds and images; this software required licensing and installation on individual machines, which prevented it from being easily accessible to everyone on the project team. The software also requires additional computing power to run smoothly, and this presented an issue for machines that did not meet the software requirements.

AstraZeneca

Tenant Fitout

"The goal of AstraZeneca's iWORK workplace strategy is to create facilities that meet expectations of how a great place to work should look and feel."

AZ Workplace Strategy Guidelines

A further goal of the fitout was to use available space more efficiently to create more collaborative, vibrant working environments to achieve a science-driven, patient-focused culture and mindset.

HH Angus provided M&E consulting engineering and IMIT communications design to the project, which presented a number of interesting challenges requiring thoughtful solutions. Among the challenges was an aggressive schedule. The team worked efficiently and collaboratively to meet the project deadlines.

The project did not allow for core drilling to feed workstations or standalone furniture. To address this, the design team and engineers had to be strategic in using perimeter and under-carpet raceways to conceal wiring. A new lighting design was implemented throughout the 5th floor, and provided a sophisticated wireless lighting control system, complete with daylight harvesting and an occupancy setting, independent of the base building control system.

During the schematic design phase, our team noted several deficiencies within the existing base building system affecting the project’s location. We requested the team have a complete site audit done by a local air balancing contractor, which identified several issues with duct connections, system operation and controls. Through this process, we were able to rectify many issues prior to the close-out phase of our project. This resulted in an efficient transition for the client, saving them both time and money.

KEY SCOPE ELEMENTS
Open floor layout accommodated despite base building risers | Base building deficiencies identified, saving client time and money | Team exceeded contract obligations in protecting client from added costs due to COVID pandemic and to ensure timely project completion

Open concept design

The client had expressed a preference for an open floor layout; however, several of the base building risers were in locations not conducive to the planned interior design. In order to accommodate the client’s wishes, we proactively identified a new shaft location, and re-routed various systems to deliver the floor layout desired by the client.

Pandemic response

The COVID 19 pandemic began in the midst of construction. The project team reacted immediately during these challenging times by providing effective and responsive coordination virtually. The team worked through construction-related delays, and helped mitigate supply distribution delays by using local contacts to expedite shipping to meet the client-requested deadlines.

The McEwan Group

Fabbrica TD

Fabbrica's second location was designed as a take-out venue. The 4200 ft2 retail space is accessed via Toronto's underground PATH system, in the heart of the city's financial district. Fabbrica on the PATH joins its sister outlet across the hall, the McEwan grocery store.

HH Angus was engaged to provide mechanical, electrical and lighting design services for the tenant fitout of the new Fabbrica on the concourse level of the TD Centre. Fabbrica took over an existing space which required ceiling demolition in order to install new lighting and electrical systems.

Custom interior lighting was designed to attract the attention of commuters and shoppers in the PATH system. To achieve this, 3500K 12W high-colour-rendering LEDs were incorporated into the lighting design to showcase the vibrant colours of the meal offerings prepared for hungry consumers.

The project's location in the concourse level posed a design challenge to the team, due to the modest amount of ceiling and underfloor clearance. To accommodate these restrictions, HH Angus designed solutions to manage the routing of piping, conduits and drainage within the limited space.
