Projects / EPSA Caserones


EPSA is a company with more than 40 years of experience in earth moving projects around the world. As their operations in the mining industry continue to grow in Chile, EPSA needed to source infrastructure solutions to meet the challenging working conditions located 4200 meters above sea level at the top of the Andes mountain range.


EPSA was looking at revamping operations at the Caserones project and needed a truck maintenance building that could be erected quickly and safely that also would conform to the stringent construction standards required to meet the environmental loads at the top of the Andes. In addition, there were a number of demanding site conditions to consider when selecting the appropriate building solution which included accessibility to site, high wind loads which often exceed 115 MPH ,as well as working conditions building infrastructure at the high altitude in the Chilean Andes.

In mid-May of 2010, EPSA contacted Sprung to supply a structure measuring 30.4m (100’ ) wide by 53.4m long (175’). Sprung’s proven track record at mining locations around the world, speed of delivery and construction, light weight aluminum substructure and large clear span relocatable design were all contributing factors in selecting Sprung as the product of choice for this demanding application.
