Faculty of Medicine Vajira Hospital, Navamindradhiraj University

Nakornping Hospital (Thai: โรงพยาบาลนครพิงค์) is a hospital located in Chiang Mai, Thailand. It is the second largest hospital in Chiang Mai with an in-patient capacity of 742 beds as of 2022. It is now serving as the regional hospital of Chiang Mai province. It is a CPIRD Medical Education Center for the School of Medicine, University of Phayao.

Navamindradhiraj University (NMU) (Thai: มหาวิทยาลัยนวมินทราธิราช; RTGS: Mahawitthayalai Nawaminthrathirat), formerly University of Bangkok Metropolis (Thai: มหาวิทยาลัยกรุงเทพมหานคร; RTGS: Mahawitthayalai Krung Thep Maha Nakhon), is a public university located in Bangkok, Thailand. The university focuses on medical science and public services such as medicine.

Vajira Hospital (Thai: วชิรพยาบาล, RTGS: Wachiraphayaban) is one of the first hospitals in Thailand, founded by King Rama VI. It is a teaching university hospital of the Faculty of Medicine Vajira Hospital, Navamindradhiraj University; the Faculty of Medicine, Bangkokthonburi University and an affiliated teaching hospital of the Faculty of Medicine, Srinakharinwirot University. It is situated on Samsen Road, Dusit District, Bangkok, Thailand.

In late September 2025, a significant ground collapse occurred on Samsen Road in the Dusit district of Bangkok, Thailand, adjacent to Vajira Hospital and the Samsen Police Station. The resulting sinkhole, which emerged at approximately 7:13 AM local time on 24 September, initially measured an estimated 30 meters in width and 50 meters in depth. This event caused severe structural damage and swallowing multiple vehicles, including a police tow truck. Prime Minister Anutin Charnvirakul, who is also an engineer, estimated that repairs would take at least a year. While no casualties were reported, the incident led to the immediate suspension of utility services and evacuation of nearby buildings as authorities assessed further risks. Following the initial sinkhole collapse, reports confirmed continued ground instability and further subsidence in the affected area to 40 meters wide. Structural assessments revealed significant cracking and slight tilting in the foundation of the Samsen Police Station, raising concerns about potential structural failure if ground displacement persists. Preliminary investigations suggest the sinkhole was triggered by a combination of underground subway construction and water pipe failure. The compromised pipe likely allowed water to erode the surrounding soil, which, combined with ongoing tunnel work and recent heavy rains, led to a sudden loss of ground stability. Responsibility for the design and construction of the tunnel and underground stations along the Taopoon–National Library section, covering a distance of 4.8 kilometers, lies with the contractor awarded Contract 1. This contract, valued at 19.43 billion baht (approximately S$778 million), is executed by the CKST-PL joint venture, which consists of CH. Karnchang and Sino-Thai Engineering and Construction. As the principal contractors, the joint venture holds accountability for ensuring the structural integrity, safety standards, and adherence to engineering specifications throughout the project duration. Consequently, any issues related to construction quality or subsurface stability within this section fall under their purview, subject to oversight by relevant regulatory authorities. This incident underscores the role of Bangkok’s characteristically soft ground in exacerbating the collapse, thereby highlighting the city’s broader susceptibility to infrastructure failures. It brings to the forefront the significant engineering and urban planning challenges confronted by rapidly developing metropolitan areas such as Bangkok. The confluence of aging infrastructure, expansive modern underground transit developments, and seasonal monsoon conditions generates complex geotechnical risks that necessitate comprehensive assessment and rigorous risk management strategies. Consequently, the sinkhole event has prompted renewed scrutiny regarding the safety standards and regulatory oversight of large-scale construction projects within densely populated urban environments.

Its name is origin of Thanon Nakhon Chai Si subdistrict of Dusit district, since it runs through the area.

The total distance is 3.185 km (round about one mi).Previously, it was named "Rachawat road" (ถนนราชวัตร). Its name was derived from a kind of Chinese porcelain with a fence-like pattern, which was a collector's item in those days. It was a road that King Chulalongkorn (Rama V) graciously ordered to be constructed and it was also one of the roads in the group of "Amphoe (district) Dusit Roads Project" that was jointly started with the construction of Suan Dusit Palace in 1898 itself was blocking the pathway of the people that resided within that area, so for the convenience of transportation and communications for the public, the king graciously ordered that Ratchawat road was to be built around Suan Dusit Palace and also the convenience of the travelling between the northern outer suburb and inner capital, and between Samsen railway station and up till the Chao Phraya river. Later on February 16, 1919, which corresponds to the King Vajiravudh (Rama VI)'s reign, he graciously ordered that the name of Ratchawat road that started from the Chao Phraya river to Prathat Thong road (now Rama VI road) to be changed as "Nakhon Chai Si road" in honour of Prince Chirapravati Voradej, Prince of Nakhon Chai Si, one of sons of King Chulalongkorn and half brother of King Vajiravudh, who considered as "Father of the Thai Army". Although it is short, Nakhon Chai Si road runs through important places, for example Rachawat bridge, a bridge over Khlong Prem Prachakon canal near the Dusit district office, Wat Amphawan, Wat Sawatwaree Simaram, Rachawat and Si Yan markets etc. In addition, the area that this road runs through is also known as "Rachawat" according its former name.
