Museums

In 2017, Niagara Parks’ engineering team began a thorough assessment of the century-old building to determine the state of its structural integrity.

The initial inspection revealed water from the Niagara River was still entering the plant and flowing into the penstocks. The large headgates that acted as a barrier had deteriorated from rust. Safety was of the utmost concern.

Based on the findings of the assessment, a concrete barrier was placed in front of the penstocks to stop water from entering the power station. A swing stage was also built to allow access to different levels of the plant where geotechnical and structural inspections were completed.

Phase 1 Construction
Phase 1 construction took place between 2018 and 2021, with most of the construction concentrated inside the 600-foot forebay to protect the generator hall.

Part of the forebay was reserved to create a 100-foot water feature that will show visitors how power generation began with water flowing into the plant. On either side of the water feature, new floor space was created for amenities such as shopping, guest services and future culinary experiences.

The original equipment in the generator hall was meticulously shined and restored to showcase the incredible power generating technology built in the early 1900s.

Heritage Preservation
As the environmental and cultural stewards of the Niagara River corridor, preserving the heritage of the power station was of the utmost importance, driving all the decisions during the adaptive reuse construction process.

A comprehensive strategic conservation plan determined what elements were most important to preserve. All the equipment showcased in the generator hall have been carefully cleaned and left as they were when they were originally built. The power station was built utilizing durable materials such as limestone, granite, brass, and copper.

More than 400 people have worked in the facility during the adaptive reuse construction, including more than 100 staff from Niagara Parks.

Featured Machinery
There are 11 generators inside the power station. The first five were installed when the power station opened in 1905. The remaining six were added up to 1924, when the plant was fully operational. The generators inside the power station have been cleaned and painted blue, the original colour prior to the power station closing in 2006.

Each of the generators has a corresponding governor that controlled and regulated the rotational speed of the turbine. The governor made it possible for the generator to produce a constant frequency of alternating current electricity. The frequency was measured in hertz. The governors you see inside the power station have been meticulously cleaned and hand-polished to preserve their heritage quality.

Exciter units were mounted on the same shaft as the main generators and produced DC power for the field windings. They weighed 45,000 pounds and created excitation powered by water. When spinning, the exciters could reach up to 600 rotations per minute! When the power station first opened in 1905, its five exciter units were placed deep underground in the wheelpit. Eventually, it was discovered the environment was too moist, and the exciters were moved to the main generating floor. The exciter placed outside, in Power Plaza, was reduced to 16,000 pounds. A special powder coating was applied to protect it from the outdoor elements.

The Workers
At Niagara Parks, we are fortunate to have many talented and diversely skilled tradespeople who played a vital role in bringing the power station back to life. During the adaptive reuse construction, we employed our electricians, plumbers, masons and laborers.

In addition, approximately 75 contractors were hired and more than 400 people have worked in the facility, including more than 100 staff from Niagara Parks.

The Kingston Pump House Museum is a demonstration of the original waterworks that served the City of Kingston in the 19^th Century.

The Pump House is located in one of Canada’s oldest original water works – where steam-powered pumps provided the first running water to Kingston residents from 1851. Only six similar preserved water pumping stations remain in North America. The assignment involved an addition to house workshops, arrival and orientation space for school groups, new accessible washrooms and office areas, as well as renovations to the existing historic building.

During excavation underground structures were discovered that were not identified in sub-surface investigations at early stages of the project. Removal of the structures and replacement with engineered backfill would have resulted in a large extra. To mitigate this, change our team mobilized on site within a few days and facilitated a meeting with between the civil contractor, the general contractor and the structural engineer to revise the footing system to avoid subsurface obstructions. By quickly addressing the issue we avoided schedule slippage.

Delay was incurred on this project due to the glazier installing curtain wall that did not match the shop drawings and specifications. Our team worked with the product manufacturers to ensure the delivered installation would still meet specified performance standards. In order to mitigate a 90-day extension to the construction schedule we instead negotiated a significant credit and applied aftermarket films to achieve the desired design. The museum was able to open on time and the overall budget was reduced.
