2006 Geotech Report - MLE Improvements.pdf

This is a Preliminary Geotechnical Evaluation report dated May 4, 2006, for the Nogales International Wastewater Treatment Plant (Project No. 601421001). The report documents site conditions through photographs and boring investigations, providing baseline geotechnical data for the facility located in Rio Rico, Arizona. Key observations include documentation of desiccation cracks on the surface near boring B-1 and various views of the plant's basin structures (northwest, northeast, southeast, and southwest basins), establishing subsurface and surface conditions relevant to design and construction planning.

This geotechnical evaluation directly supports the related Design-Build solicitation (191BWC26R0010) issued by the International Boundary and Water Commission (USIBWC) for construction of the Sludge Dryer Building. The preliminary geotechnical data from this 2006 report informs the Phase 1 design activities required in the current solicitation, which include site investigation, surveying, and geotechnical investigations necessary for developing construction documents for the new sludge dryer facility. The evaluation provides essential baseline information for contractors responding to the design-build contract, which requires completion within 365 calendar days after Notice to Proceed and is anticipated to be set-aside for small businesses.
