Development of the eastern saijo (tentative name)

　In Motoichi, declining birthrate and aging progress more and more in future, and aging rate is expected to exceed 26% in 2025 (Reiwa 7). The number of deaths is expected to increase, and the demand for cremation is expected to continue to increase.
　Currently, the city's saijo is operated by the municipal 4 saijo and the private 1 saijo, and the municipal saijo has made various efforts to maintain a stable supply of cremation over the future.
　The city recognized this situation as an urgent issue, and decided to develop a new saijo to meet the increasing demand for cremation.

Location: 18-18, Daikokucho, Tsurumi-ku, Yokohama-shi and others

※This is the current assumption. It is subject to change depending on future business progress.

　In order to convey the progress of our business, we have published a public relations paper called the Eastern saijo (tentative name) Maintenance Communication.

　We hold briefings to inform the progress of our business.

　About eastern part saijo (tentative name) maintenance business, we carried out public works evaluation (prior evaluation) based on Yokohama-shi public works evaluation system in 2019. As we decided prior evaluation record based on deliberation result of Yokohama-shi public works evaluation committee and citizen opinion offer result, we announce result as follows.

　For an overview of the system, please see the page of the Finance Bureau Facility Management Promotion Section.

　On February 4, 2022, the city planning change of the crematorium (addition of eastern saijo) was announced. The name of the city planning is "Tobu saijo", but the current name is "Tobu saijo". The name as a citizen-use facility will be determined in the ordinance of the City Counsil, with reference to the opinions of those involved.

　When we establish crematorium newly and are going to run, it is necessary to receive permission based on law about graveyard, burial. In addition, in receiving permission, it is necessary to perform procedure based on the regulations about permission of management such as Yokohama-shi graveyards.

　The following is a report on the progress of the project.

　The eastern saijo (tentative name) will drill about 8 meters of ground to build a parking lot on the first basement floor.
　Mountain retaining work was carried out in advance so that the surrounding soil to be excavated does not collapse. The construction method for the retaining work is based on the SMW method so that the surrounding groundwater does not flow into the area dug.
　In earthwork, we plan to proceed with the construction in two stages: primary drilling and secondary drilling. Currently, we are digging to the depth of the primary drilling and constructing an earth anchor to support the mountain retaining.

　The builder of the construction work was decided to be Taisei, Matsuo, and Watanabe Kensetsu consortium, and a temporary enclosure was set up in June, and the ground improvement work was started immediately in July. (Static tightening sand pile method: A steel pipe (casing pipe) is penetrated into the ground, sand is injected into the ground from the steel pipe, and a cylindrical sand pile with a diameter of about 70 cm and a depth of about 6 m is installed. This prevents liquefaction of the ground during a major earthquake. )
　In addition, the installation of two temporary site offices has been completed on the land adjacent to the construction site, and construction has begun in earnest.

　In the eastern saijo (tentative name), air conditioning is performed using underground heat.
　In order to utilize this geothermal heat, underground heat exchangers (U-shaped plastic pipes with a diameter of about 3.5 cm) were installed at 49 locations within the saijo project site.

<Reference: What is the use of underground heat?＞
　The temperature inside the ground, which is more than 10m above the surface, is almost stable, not only in the season, is cooler than outside temperature in summer, and warmer than outside temperature in winter. The use of this stable heat is called "ground heat utilization."
　In order to use this underground heat, the underground heat exchanger will be embedded deep underground and water will be circulated to collect heat and use it for cooling and heating.
