McGill University Health Centre Glen Site

The McGill University Health Centre (MUHC) Glen Site is yet another example of our expertise in designing to LEED® (Leadership in Energy and Environmental Design) standards. Located in Montreal, Canada, the project is one of North America’s biggest public-private partnerships. It was also one of Canada’s largest construction sites with nearly 12,000 workers and 14 cranes equipped with the country’s first anti-collision system.

We helped arrange project financing, then designed and built the centre to LEED Silver certification standards. We delivered the cutting-edge, patient-focused healthcare facility in late 2014. Our team will operate and maintain it until 2044.

Here are some of the steps we took to meet and, in some instances, go beyond LEED Silver certification.

  • We reused and recycled 95% of construction waste and debris, 20% more than the LEED Silver standard requirement.
  • We used construction materials with high recycled content, including the metal aluminium cladding, reinforced steel and green Rocksul rock wool.
  • A retention basin is used to manage the discharge of wastewater into storm sewers during heavy rain.
  • We procured 20% of construction materials from local suppliers (less than 800 kilometres from the site), reducing greenhouse gas emissions associated with transporting materials.
  • The hospital will consume 35% less energy than conventional Canadian hospitals thanks to several energy-efficiency measures.
  • We implemented diverse solutions to recover heat from the exhaust air and boiler combustion gases.
  • The 92 roofs comply with LEED criteria and use white stones to significantly reduce the heat island effect. Underground parking and green spaces will also lessen this effect.
  • Automated interior lighting control systems in every room will minimize electricity consumption.
  • Low-flow faucets will reduce potable water consumption by at least 30% compared to similar buildings.
  • We installed 333 parking spots for bicycles and showers for staff who cycle to work. We also built bicycle paths linked to the local network of cycling paths.
  • We set up 79 charging stations for electric vehicles.
  • A waste management centre will sort paper, cardboard, electronic waste, glass and plastic for recycling by an external company.
  • We applied paint free of volatile organic compounds (VOCs) to the hospital walls.

John Hart Generating Station Replacement Project
In early 2014, we won the contract for a new generating station in British Columbia, Canada, by proposing a groundbreaking, cost-competitive design: we put the powerhouse underground. Not only did our design focus on protecting the environment, it also boosted the project’s social acceptance.

Building the powerhouse underground will enhance public safety and river recreation while reducing the project and site’s environmental footprint. A new water bypass facility will protect the downstream fish habitat by providing flow continuity below the generating station. Approximately 95% of the Campbell River flow passes through the John Hart Generating Station.

The new generating station will be more seismically robust than the existing facility. It will also ensure a more stable and sustainable source of energy on Vancouver Island for generations to come.

“BC Hydro is very pleased with the design of the John Hart project, along with the social and environmental benefits that include most of the existing surface hydroelectric facilities going underground with the area then remediated and re-forested to better fit within the surrounding Elk Fall Provincial Park.

The new facility’s downstream water discharge to protect downstream fish habitat, in the event of generating station equipment issue, will go to seconds rather than the approximate one hour existing timeframe to recover river flows. From improved trails, to wildlife and fish enhancements, and just as importantly the various considerations for fish and wildlife during the five-year construction period, it’s all lining up to be a successful project with continued strong community support.”

Confederation Line Light Rapid Transit Project

In Ottawa, Canada’s national capital, the Confederation Line Light Rapid Transit Project will convert the city’s existing bus rapid transit corridor into a full LRT system as well as widen and rehabilitate a four-kilometre section of Ontario’s Highway 417. In addition to improving the system’s reliability, comfort and convenience, the project will:

  • increase ridership
  • reduce air pollutants and greenhouse gas emissions
  • improve mobility
  • create jobs
  • foster economic development

- Reducing emissions
The project is also expected to decrease CO2 emissions by approximately 94,000 tonnes in 2031. It will also reduce criteria air contaminant emissions by approximately 4,600 tonnes in the same year. Vehicle kilometres travelled will also drop, reducing overall vehicle operating costs, accident costs and road network congestion.

- Downtown core redevelopment
The project will enable the downtown’s redevelopment and transit-integrated development. This will help Ottawa achieve its targets for increased re-urbanization and intensification. It will also help protect agricultural and sensitive environmental areas against urban population and expansion pressure. Land use changes involve redeveloping and reclaiming brownfield sites that are often contaminated and underutilized, resulting in more productive and beneficial use of these lands.

- LEED
Both the administration and maintenance buildings were designed for Leadership in Energy and Environmental Design (LEED) certification and will be registered with the Canada Green Building Council (CaGBC).

- Sustainable design and construction
We developed and implemented a sustainability plan to ensure the line’s design and construction are aligned with Ottawa’s ‘Choosing Our Future’ initiative as well as its environmental and sustainability strategies.

Gorgon Liquefied Natural Gas Project

The Chevron-operated Gorgon Liquefied Natural Gas Project is one of the world’s largest natural gas projects and the largest single-resource development in Australia’s history. It’s located 60 kilometres off Australia’s northwest coast on Barrow Island. Barrow Island has been a Class A Nature Reserve since 1910 and is an internationally important conservation estate.

Kentz has been working on the project in various capacities since 2009. We’re also playing a key role in protecting Barrow Island’s flora and fauna through compliance with the Gorgon Project’s quarantine management system. In 2014, our joint venture with CB&I received two Golden Barrow Environment Awards for our contribution to protecting Barrow Island.

Cerro Negro Norte Iron Ore Mine

Our Thickened Tailings Disposal (TTD) system is delivering significant environmental benefits at the CAP Minerias Cerro Negro Norte iron ore mine in Chile. The project is the largest-scale installation of this advanced technology.

Our industry-leading TTD technology thickens tailings to a consistency of hard soil by removing over 85% of the water. This prevents water infiltration, eliminates dust and allows the tailings to be used to contain other tailings. It also provides enhanced protection in the event of seismic events. The recovered water is reused in the mining process.

Halifax Central Library

One of the world’s most visually striking libraries is also one of its greenest. Located in Nova Scotia, Canada, the Halifax Central Library was designed and built to achieve Leadership in Energy and Environmental Design (LEED®) Gold certification from the Canada Green Building Council (CaGBC). Our structural and civil engineers found novel solutions to successfully deliver the building’s challenging and complex geometry and sustainability features.

For a library, sustainability means the facility needs to be built to last with a reduced operational environmental impact. It must also offer the flexibility to meet changing program requirements and support users’ social and cultural needs. The design team worked diligently to deliver on these commitments, integrating sustainable features and materials to ensure the buildings’ optimal performance.
