Vibration Monitoring during Widening of Existing Ford Road/Bonita Canyon Dr. Undercrossing Northbound Bridge on State Route 73, Orange County, CA - Project Manager for conducting a vibration monitoring program to measure vibrations generated due to pile driving operations for installation of a deep foundation system for the proposed widening of the Existing Bonita Canyon Dr. undercrossing bridge on State Route 73. The measurements focused on monitoring ground velocity time histories and peak particle velocities (PPV) at surface and depth to evaluate its effects on structural integrity of the Metropolitan Water District (MWD) concrete encased 55-inch water pipeline passing under Bonita Canyon Dr. Bridge between Abutment 1 and Bent 2. Vibrations were measured with surface and downhole 3- directional geophones (triaxial seismometers). Four seismometers (3 on the ground surface in a row perpendicular to the pipeline alignment and 1 at depth) were used to evaluate attenuation of the ground vibrations with distance from source and its potential adverse effects on structural integrity of the feeder during construction compromising the reliability and continuity of the MWD conveyance system. Client: Jacob Engineering Group/MWD.
Jensen Filtration Pl ant Post-Northridge Earthquake Seismic Investigation, Granada Hills, CA An experimental and engineering analysis investigation was performed by HAI to study dynamic response of several structures at the filtration plant and determine effect of the site soils on recorded ground motions at the filtration plant. The site soils liquefied in some areas during the 1971 San Fernando earthquake, which resulted in major damage at the facility. The Northridge earthquake, however, did not cause substantial damage at the site of the plant. Understanding dynamic response of soils at this site and its effect on water filtration/treatment and conveyance structures is essential because of the critical nature of facility, which should remain operational in the event of a major earthquake.

RELEVANT EXPERIENCE
City of Watsonville Sanitary Landfill, Watsonville, Santa Cruz County, California (April 2023 - present) CQA Monitor supervising the 7-acre Phase (Cell) 4 Landfill Expansion Project Composite Liner construction and the 6 -acre Phase 3 L andfill Cover construction . CQA responsibilities included inspection , documentation, and testing of geosynthetics installation and backfill soils placement (nuclear gauge and sand cone density testing of the subgrade and compacted clay liner, cover soil, and operation layer) .
Inspected assembly of mechanical elements of leachate collection and re moval sy stem (LCRS) such as piping and pumps. The LCRS is designed to drain leachate to collection sumps which consist of an HDPE riser and submersible pump. Leachate drains to the leachate collection system, where it is transferred to a central collection pump and piped to an onsite holding pond. If necessary, the leachate is transported to an approved offsite wastewater treatment plant for disposal. The system is designed to automatically pump leachate to maintain compliance with state requirements.
Observes and documents installation of landfill gas (LFG) collection and processing mechanical systems.
Instead of escaping into the air, LFG is captured, converted, and used as a renewable energy resource.
LFG is extracted from landfills using a series of wells a nd a blower/flare (or vacuum) system. This system Woody Drew Arnold Field Engineer
directs collected gas to a central point where it can be processed and treated depending upon the ultimate use for the gas. From this point, the gas can be flared or beneficially used in an LFG energy project.
