The focus of this project was primarily on regulatory compliance, current water infrastructure analysis, water conservation, and reuse applications.  As part of a dynamic team, future forecast demands and current potable water use were assessed and recommendations made to implement water reduction measures for support of current and future water demands. 

This project was completed while employee was under a different company. 



Project scope includes elevation and re-enforcement of a residential structure built in the 1940’s located on the Pacific coast. Tasks included analysis of existing foundation, enhancement of existing structural composition, and addition of interior structural support. Project completion involved the redesign of the foundation and structural components to include a stem wall.


Stabilization of Existing Structure During Excavation

Construction oversight focusing on stabilizing the foundation of a storage structure during contamination excavation.

After the excavation was completed and all contamination removed, the soil was compacted according to the required bearing capacity for a new structure and parking lot. Tasks included oversight, health and safety, and completion of daily quality control reports (DQCR) required by the USACE.
