​Client: St. Catharines Hydro Generation Inc.
​St. Catharines Hydro Generation Inc. retained ELLIS Engineering Inc. to complete the detailed structural design, specifications, and drawings for the construction of a 4.2 megawatt hydro-electric generating station and control structure on Twelve Mile Creek in the City of St. Catharines. The powerhouse structure included four Mavel Kaplan Pit turbines and the control structure included four Andritz Hydro overshot gates. The new structure was designed as a low head, run-of-the-river generating station with an average flow rate of 200 cms. ELLIS Engineering Inc. completed the structure design, global stability design checks and coordinated the integration of the turbines, gates, stop logs, trash rakes, fish passage system, mechanical and electrical components.

Ontario Power Company Tunnel Inspections

​Location: Niagara Falls, ON
​Client: Niagara Parks Commission
ELLIS Engineering Inc. was retained by the Niagara Parks Commission to complete structural inspection of the Ontario Power Company Generating Station’s three decommissioned hydro tunnels, which extend under portions of the Niagara Parkway. The three conduits were constructed between 1905 and 1912 and extend from the gatehouse just south of Dufferin Islands to the Ontario Power Company generating station just south of the base of Murray hill in the City of Niagara Falls, Ontario. The three 1.8km long tunnels include: a steel-lined conduit, a reinforced concrete conduit,
and a timber-lined conduit. Access to the confined space was provided by GeoArc Industrial Inc. ELLIS provided detailed visual inspection of all components, identified effects of deterioration, damage, structural deficiencies, and hazards. ELLIS prepared a structural inspection report including recommendations for rehabilitation.

The project scope included preliminary and detailed design, as well as contract administration for the rehabilitation of the bridge. Golder Associates were retained to complete a detailed condition survey. The construction contract was awarded to Rankin Construction Inc. ELLIS provided contract administration and site inspection services during construction.

Niagara Power Generating Station Forebay Bridge Reconstruction

​Location: Niagara Falls, ON
​Client: Rankin Construction Inc./Niagara Parks Commission
The reconstruction of the Canadian Niagara Power Forebay Bridge was completed with Rankin Construction as a design-build project. ELLIS Engineering Inc. completed the design for the reconstruction of the CNP Forebay Bridge, and also the rehabilitation and conversion of the adjacent Ice Bridge for pedestrian use. The existing five span stone arch structure was built circa1905 at the forebay of one of the first power stations in the world, near the brink of the Horseshoe Falls. An innovative approach was taken to build a new bridge superstructure, saving the 1905 stonework, and retaining the look of the original arched bridge. The new reinforced concrete deck was cast in place using the existing arches as formwork. The existing arched stonework was tied into the new concrete deck via ‘edge beams’. New architectural features, such as railings and light poles were provided to match the surroundings and nearby structures.

Canadian Niagara Power Generating Station Tunnel Project

​Location: Niagara Falls, ON
​Client: Rankin Construction Inc./Niagara Parks Commission
ELLIS Engineering Inc. (ELLIS) was retained by the Niagara Parks Commission (NPC) to provide design and construction inspection services as part of a design build project with Rankin Construction Inc. (Rankin) to repurpose the decommissioned Canadian Niagara Power Generating Station for a new NPC attraction called “The Tunnel”. ELLIS completed the detail design and drawings for an elevator shaft, a 670m long walkway through the Tunnel, and a viewing platform at the Tunnel outlet consisting of a reinforced concrete walkway with a pedestrian railing, constructed on top of rock fill. Gates were also designed and installed at the Tunnel outlet.
