IICA ANNOUNCES THE PARTICIPATION OF THE INTERNATIONAL FINANCE 
CORPORATION IN THE IRAPUATO-LA PIEDAD PPP PROJECT



Mexico City, September 21, 2006  Empresas ICA, S.A.B. de C.V. (BMV and NYSE: ICA)announced today that the International Finance Corporation, IFC, the private sector arm of the World Bank, has provided a partial credit guarantee of up to Ps. 130.5 million for the financing approved by Santander-Serfin for the expansion, modernization, and operation of the Irapuato-La Piedad highway. The Public Private Partnership (PPP) concession and service contract for this highway was awarded to an ICA subsidiary by the Ministry of Communications and Transport (SCT) in October 2005.

IFCs participation in this project confirms the strength and viability of the PPP structure. The Mexican government has been developing the PPP mechanism for the past three years, and ICA has participated actively in the development process, said Alonso Quintana, ICAs Administration and Finance Director.

Franciso A. Tourreilles, IFCs Director of the Infrastructure Department noted, IFC is pleased to be working with ICA and Banco Santander in this path breaking PPP transaction in Mexico. It will have an important demonstration effect for PPP infrastructure projects in that country and, more broadly, in Latin America. We believe that the successful development of effective private-public partnership models such as this one will play an important role in helping attract critically needed private investments in infrastructure in the region.

Santander is committed to the financing of infrastructure in Mexico. We are grateful to ICA for their confidence in selecting us as Advisor and Bookrunner for the first PPP transaction in Mexico. IFCs participation contributed to the success of this transaction, and we look forward to working together on other transactions in the future, said Octaviano Couttolenc, the Santanders Head of Structured Finance in Mexico.
