Description

This Spanish public procurement tender, located in Madrid, is for the construction of infrastructure supporting a semiconductor facility. It is split into two distinct lots. The first lot involves the construction of an underground 66kV power line and associated switching station. The second lot covers the construction of a research and development complex. Critically, this complex will include a cleanroom environment essential for 300mm wafer research and development, adding a high degree of technical complexity to that specific lot.

The total published value is approximately €189.4 million. This suggests a project of significant scale, requiring substantial resources and experience, particularly in cleanroom construction for the R&D complex. Given the tight deadline of one week from publication to submission, contractors must act quickly to assess the tender documents and determine if they possess the necessary qualifications, expertise, and capacity to compete effectively. The project also demands proficiency in Spanish regulations and standards within the construction sector.

The presence of a cleanroom within the R&D complex implies stringent adherence to environmental control, material selection, and construction methodologies. Bidders should also consider the electrical infrastructure component involving a 66kV underground line to factor in high-voltage engineering expertise.

Original description

This tender is divided into two lots: construction of an underground 66kV line and switching station for a semiconductor center, and construction of a research and development complex for 300mm wafers, including a cleanroom.
