According to local media Regina Leader Post, the Clayton municipality applied for funding in the fall of 2017 through the Saskatchewan-administered Municipal Roads Program. In January of the following year, the program management committee approved the funding application and decided to construct the Dyke Memorial Bridge.
The Dyke Memorial Bridge opened on September 14, 2018. However, the Dyke Memorial Bridge collapsed on the day it opened. No one was injured in the collapse of the bridge.
Jay Meyer, Executive Producer of the Municipal Roads Program for the Saskatchewan government, said the state had been requesting Clayton's local government for months to submit engineering standards for the bridge, but Clayton provided the materials. It seems that it was never done.
The total cost of constructing the Dyke Memorial Bridge is 1.1 million Canadian dollars (about 120 million yen), of which up to 750,000 Canadian dollars (about 81 million yen) will be funded by the local government road program. It was planned. However, the subsidy that was finally paid to Clayton from the program is 350,000 Canadian dollars (about 40 million yen).
About this, Mr. Meyer said that the municipal road program only recommended a specific bridge design, and explained to Clayton, 'This bridge exceeds our needs. We do not need this bridge.' is revealed.
According to Doug Wakabayashi, spokesman for the Saskatchewan Department of Transportation, Clayton Municipality used 'concrete and wood pilings that are commonly used in bridge construction' to build the Dyke Memorial Bridge. It seems that it was 'a pile used to construct a deck' instead. Wakabayashi also pointed out, 'We are fairly consistent that bridge designs funded through our road planning program must be proven to be safe.' In addition, the Saskatchewan state government explains that 'bridges under the Municipal Road Program are expensive but safe.'
According to Duane Hicks of Clayton Municipality, Can-Struct Systems was responsible for the construction of the Dyke Memorial Bridge, and it seems that the company will be in charge of repairing the collapsed bridge. The repair cost of the bridge was estimated to be about 340,000 Canadian dollars (about 37 million yen).
Then, in 2023, the Disciplinary Commission of
The APEGS Disciplinary Committee has described the collapse of the Dyke Memorial Bridge as a 'catastrophic failure' and has also issued an order to investigate Mr. Gallatcher's misconduct on multiple projects, not just the Dyke Memorial Bridge. Masu. The regulator noted that Gallacher had not conducted a geotechnical analysis of the construction site and had not conducted a proper engineering design for the spiral pile foundation. In addition, Mr. Galatcher has received disciplinary action for design work on five other bridges.
The Disciplinary Committee also stated that Mr. Gallacher's design of the bridge 'has a lack of design information, including imprecise wording, in the design of the bridge, resulting in an inability to support the minimum loads required by the Code.' Enough five superstructure designs were born, ”explained the cause of the collapse of the bridge.
At the time of writing the article, Mr. Garatcher says he lives and works outside Saskatchewan, but he wants to return to Saskatchewan and work as an engineer. The 18-month suspension given to Mr. Garatcher has been in effect since June 8, 2022, so the suspension will be lifted in December 2023.
However, even after returning, Mr. Garatcher will be prohibited from engaging in a bridge project in Saskatchewan for five years. In addition, Mr. Gallacher will be subject to APEGS supervision for three years after suspension and will need to receive five hours of verifiable ethics training in three years.
In addition, Mr. Gallacher needs to pay APEGS a research fee of 32,000 Canadian dollars (about 3.5 million yen) and a fine of 15,000 Canadian dollars (about 1.6 million yen) imposed by APEGS.
In addition, Mr. Galatcher testified that he paid 250,000 Canadian dollars (about 27 million yen) on his own to restore the Dyke Memorial Bridge.
