BAUER Fundaciones Panamá S.A. has successfully finished the construction of two foundation elements for Trasvase Daule-Vinces irrigation project. SENAGUA, the Ecuadorian Water Authority, awarded Bauer with the execution of approximately 6,200 m² of plastic concrete cut-off wall and 7,632 m² of reinforced concrete diaphragm wall.

The plastic concrete cut-off wall will serve as seepage barrier to the main lock system. It consisted in the excavation of 165 single bite panels in 3 different alignments up to maximum 27 m deep achieving full completion by October 2013.

The reinforced concrete diaphragm wall is designed to stabilize and protect the new river slope. Works included the excavation of panels up to 15 m deep and 7.2 m wide over an extension of 509 m, in total 7,632 m² of diaphragm wall. The works were carried out from November 2013 to January 2014 over 75 working days, 25 of which during the rainy season.

Scope of works:

• 6,200 m² of plastic concrete cut-off wall with maximum penetration depths of up to 27 m
• 7,632 m² of reinforced concrete diaphragm wall with excavation of panels up to 15 m deep over 509 m of extension
