POINT OF INTERESTGTAA Central Utilities Plant and Infield Concourse Hot Water Pipe Replacement

Located in Oshawa, Ontario, the Harmony Creek Water Pollution Control Plant (WPCP) is rated at 34,000 m3 per day and treats sanitary wastewater from Oshawa and Clarington. This facility is a conventional activated sludge treatment plant which utilizes anaerobic digestion for sludge stabilization.

Work for this contract is nearing completion and required refurbishment, upgrades, and expansion to several areas of the plant. Upgrades to the secondary and solids treatments processes consisted of refurbishment of digester 1, conversion of digester 2 to a biosolids storage tank, new digester steel roofs, and replacement of the heat exchanger. Upgrades to the digestion gas system were also completed, including rerouting of gas piping and flare installation, replacement of two secondary clarifier chain and flight sludge collection systems, and two high-speed blowers.

Expansion work consists of construction of a new biosolids thickening facility including two glass-lined biosolids thickening tanks, a new polymer dosing system, new administration building complete with laboratory, offices and changing areas, and implementation of a plant-wide SCADA network. Building upgrades include HVAC modifications, architectural and structural improvements.

Construction began in February 2018 and is scheduled to be substantially completed by December 2019. The existing facility has remained fully operational throughout construction.

Introducing the new www.kenaidan.com

The Greater Toronto Airports Authority (GTAA) Central Utilities Plant (CUP) and Infield Concourse (IFC) Hot Water Pipe Replacement project was a fast-track replacement of hot water lines, the main source of the heating system for Terminal 1 at Toronto Pearson Airport. This critical repair and replacement contract required re-installation of the heating lines in time for the heating season. The project required the excavation, removal, and replacement of 80 m of 500 mm steel pipe, buried at a 4 m depth.

Due to the nature of fast-track repair projects, unforeseen challenges and schedule impacts

can be detrimental to the success of a project. One such challenge was the discovery of an interference with routing of the new buried piping and the existing footings of a steel structure.

With the heating season looming, and the potential impacts to provide the needed services, Kenaidan’s Engineering Department developed six different solutions to resolve the issue. The selected approach was to construct a temporary support structure to transfer the loading of the interfering support column. This allowed for the removal of the existing footing to run the buried heating piping. Due to space

limitations, micro-piling was utilized to support existing structures while installing the new buried piping. The new design replaced the footing and set the structure back in place. Adjustments were made to the routing of new piping to avoid this interference and potential future expansion projects.

Kenaidan successfully commissioned and re-instated heat through the new piping on September 22nd, 2019, in time for the Toronto Pearson Airport heating season.

Setting an ExampleO U R M E S S A G E

With the elections over, it has become clear that the environment is a hot topic that Canadians are holding dear. In this past election, most parties had to have some sort of environmental plan and if you didn’t, you ignored a large percentage of voters. We may not be able to drastically affect climate change, being a country that creates a small percentage of the problem, but we can set an example as Canadians on the world stage; this includes leading by example on our job sites.

I am not proposing massive changes in the way we do things, especially ones that cost lots of

money. However, there are a lot of small things, that when added together, can make big environmental impacts and can save money.

Here are some of the things we can do on our job sites and at home:

• Separate our garbage by having several labeled bins (concrete is cheap to get rid of if not contaminated and garbage is expensive if contaminated with concrete and metal)

• Bottles and cans will be picked up for recycling by the City/Municipality for free on recycling day

• Make sure that we have adequate power panels to limit the use of generators (they take a lot of fuel and require someone to fill them)

• Put thermostats on temporary heaters• Use refillable coffee mugs and water bottles • Turn off equipment and pick-up trucks when not in use• Take your own bag to the grocery and hardware stores

There are many little things we can do in our daily lives to help reduce our environmental footprint. If everyone does a little, it will add up to a lot, and ultimately can make a big difference.

On November 28, Kenaidan’s Head Office atrium was turned into a popular game show set… the Fabulous Feud! Employees teamed up to test their knowledge. “Survey Says”… it was a fabulous event!

At our Keele Station, Easier Access Phase 3 project, Kenaidan and TTC teamed up to offer riders free coffee and muffins. Our way of saying thank you for their patience during construction.

Starting midnight on October 23rd, our GTAA CDF Improvements and Glycol Storage Tank project team placed 460 m3 of concrete in 8 hours. Kenaidan self-performed all aspects of the pour with a 10 man crew and a 65m pump. The pour was a success and crucial to completing the tank and maintaining the aggressive schedule.

Don Pletch (left) and Will Gaete (right) put on their happy faces to celebrate the successful concrete pour.
