Creating an Entirely New オンライン カジノ 入門 Racecourse

Just before the reopening of the new Centennial Park オンライン カジノ 入門 Racecourse (As of February 2023)

Take the Keihan Main Line from オンライン カジノ 入門 city center to Osaka and you will be struck by an eye-catching construction site just before arriving at Yodo Station. オンラインカジノ has been renovating the オンライン カジノ 入門 Racecourse, which will celebrate its grand reopening in April 2023.


100 years of tradition for future generations

The オンライン カジノ 入門 Racecourse was first constructed in 1908 when modern horse races were held in Shimabara, Shimogyo-ku, オンライン カジノ 入門. After moving to Kyotamba Town in 1925, the racecourse was constructed on the current Yoshijima Watashibajimacho site in Fushimi-ku. The rebuilding of the grandstands and renovation of all other facilities including the stables and racetrack are currently underway as part of a commemorative project to mark the course's 100th anniversary in 2025.

The project has been divided into three zones and Obayashi is in charge of the grandstand オンライン カジノ 入門 zone. The new grandstand at 35 meters will be the same height as the current Grand Swan stand that is earmarked for demolition in this project. However, the ceilings on each floor will be higher to create a spacious and open atmosphere. Shifting to cashless ticket purchases has facilitated a reduction in the size of the backyard. The newly transformed state-of-the-art horseracing facilities will offer more spacious customer areas and greater convenience.

The side of the new grandstand facing the track will feature powerful horizontal lines created by an interlayer truss structure with a 25-meter cantilevered frame. It will make for a magnificent landscape, together with the pond filling the inside of the course. The rear of the grandstand facing the paddock, where spectators can go to see the condition of the horses before the race, is a hybrid structure that combines natural wood and steel. It features large eaves fortified with horizontal braces and gracefully curved step-like green terraces.

Racecourse use is the top priority

Transferring the functions of the stands set for demolition

Races at the オンライン カジノ 入門 Racecourse will be closed for about two years from November 2020 when the dismantling of the Grand Swan building starts. However, during that time, Park WINS (a nickname for off-track betting) will be held every Saturday and Sunday. That meant the renovation work such as relocating various functions and transferring infrastructure to enable betting slips to be sold in the Big Swan building, which was not being dismantled, must be carried out.

Furthermore, with off-track betting going on throughout the renovation period, the ticket sales system had to be checked every Friday to confirm it was properly linked to other racecourses in Japan. Renovation work week was therefore confined to Monday to Thursday, and many restrictions were on this project.

So that the Big Swan could be kept open for customers over the weekend, demolition work on the Grand Swan was carried out with restricted movement of goods on and off site and within limited permitted areas

Surveying water levels at the site between rivers

Challenging of soft ground and groundwater issues

Grout machines lined up to improve the ground and control water pressure. Additional work was carried out on cut-off walls, sheet piles, and anchoring to further stabilize the ground.

The オンライン カジノ 入門 Racecourse is located between the Uji River and the Katsura River. To ensure the effectiveness of measures to control water during the underground portion of the stand construction, water level surveys of groundwater under pressure (artesian groundwater) were conducted in advance over a period of roughly six months. As a result of those surveys, the water levels were higher than the data originally given would suggest, and that the water level was particularly influenced by the water level of the Uji River. That indicated a potential seasonal risk of heaving (when upward water pressure acts on the lower surface of the groundwater layer causing a rise in the excavation floor).

As a necessary measure, we grouted to make the solid firmer. Around 100 machines were brought onto the vast site to inject chemicals to solidify the ground. Reducing the オンライン カジノ 入門 time was one of the most important considerations, but the plan had to be changed to take all possible measures to prevent any heaving that might cause a major accident later on.

When constructing the new elevator in the Big Swan building, wellpoint dewatering pipes were driven into the ground during the excavation to suck up the water when the bottom concrete was being casted.

Thorough review of materials, equipment, and オンライン カジノ 入門 methods

Steady progress is being made in the オンライン カジノ 入門 of spectator seating in the 255-meter-long grandstand running east to west.

Various changes to the initial plans involving such aspects as materials, equipment, and オンライン カジノ 入門 methods have been made to help shorten the オンライン カジノ 入門 period. When building the foundation for the new stand, the racecourse parking lot was used to process and assemble rebars for the piles and pre-assemble foundation beam rebar units. Reinforcement inspections were also carried out on the parking lot before the assembled rebars were transported to the オンライン カジノ 入門 site for installation. By splitting the work into processes that had to be done on the オンライン カジノ 入門 site and those that could be done outside the site, work can be done at their own pace without being influenced by the progress of subsequent processes. This was just one way to reduce worker waiting time and not bring on-site work to a grinding halt.

In addition, the scaffolding used for the finishing work on the stand's large roof and eaves was changed from mobile partial scaffolding to full suspended scaffolding. This enabled many workers to work on different sections of the scaffold simultaneously, not only at various height levels but also across the same level. In another measure to reduce the オンライン カジノ 入門 period, the number of cranes was increased from the original 8 to 13 and they were retained longer than originally planned, in accordance with the site policy of using machinery to supplement human effort, which has its limits.

Multiple オンライン カジノ 入門 projects were proceeding simultaneously on the site. Therefore, ensuring efficient オンライン カジノ 入門 by redrawing work allocation plans on a daily basis in order to reduce any factors that might result in accidents or losses were needed.

Boosting productivity with a 1,500-strong team

On the day that this interview was conducted in November 2022, 93 people from Obayashi and 1,300 people from suppliers and subcontractors were working on site. When オンライン カジノ 入門 peaked, supplier and subcontractor employees alone exceeded 1,500. In オンライン カジノ 入門 work that adheres to a strict process, you have to align the goals of many involved parties and improve productivity, so on-site key word was "ultra-short オンライン カジノ 入門 period."

Shorten meeting times, make quick decisions, and work efficiently. According to the project director who supervised this challenging オンライン カジノ 入門, Mr. Yoshihiro Maeda, "It's not just about reducing hours, but about reviewing all operations from the perspective of making them ultra-short and encouraging everyone to be conscious of the need to boost productivity. That's how to implement true work style reform and deliver high-quality buildings."
