ICA ANNOUNCES FILING OF DEMAND FOR REVIEW OF THE RULING ON 
THE AWARD OF THE QUERETARO-IRAPUATO HIGHWAY UNDER THE PPP MECHANISM



Mexico City, March 1, 2006  Empresas ICA, S.A. de C.V. (BMV and NYSE: ICA), the largest engineering, construction, and procurement company in Mexico, announced today that it has filed a demand for review (recurso de revision) with the Ministry of Communications and Transport (SCT) with respect to the SCTs ruling on February 8, 2006, that declared void all the bids for the Queretaro-Irapuato highway under the PPP (public-private partnership) mechanism.

ICA seeks the suspension of the second call for bids for the Queretaro-Irapuato highway, the partial revocation of the February 8, 2006 ruling, and to be awarded the project.

ICA believes that its demand for review is supported by the facts that the bid made by ICA is solvent and transparent, does not fail to comply with any requirements established in the bidding documents, and does not violate any legal requirements.
