NADBank provides construction loan for sustainable medical complex in San Luis Rio Colorado, Sonora

Mexico City, Mexico – The North American Development Bank (NADBank) and Nueve Uno Integradora, S.A. de C.V., signed a US$14.2-million loan agreement to finance construction of the OSME medical complex in San Luis Rio Colorado, Sonora. This project will increase access to general and urgent healthcare services for local residents, as well as for agricultural workers and their families in the southwestern region of the United States.

The project consists of the design, construction and operation of a private hospital with space for 67 beds, emergency room, intensive care unit, radiology and laboratory, among other areas, along with a medical specialties center.

“This project is the first sustainable building to be funded by NADBank,” said NADBank Managing Director Calixto Mateos Hanel. “The new facilities are expected to use 43% less water than conventional medical establishments and 18% less electricity, which will increase access to affordable and sustainable healthcare services in the region. 

Nueve Uno Integradora, S.A. de C.V. will incorporate sustainable construction techniques and thermally efficient building materials, which are expected to generate significant water and energy savings. In the latter case, the complex is expected to save an estimated 257 megawatts-hours (MWh)/year in electricity, which is similar to the annual consumption of 34 households.  

Once the new facilities are operational and reach full capacity, up to 33,800 primary care physical exams are expected to be performed annually, and the number of hospital beds in the city will increase 57%, from 117 to 184. 

The loan was made through the NADBank COVID-19 Recovery Program (ProRec).
