utility systems, including potable water,
<br />reclaimed water, hydronic water, sanitary sewer,
<br />and natural gas. An array of uti I ity testing and
<br />tasks performed were visual assessments of
<br />above/belewground components and manholes,
<br />the ultrasonic thickness of accessible metallic
<br />components, leak detections, and confined
<br />space entry into the manholes and underground
<br />tunnel systems. Also, concrete testing through
<br />concrete sounding, concrete penetration,
<br />concrete surface pH, surface penetrating radars
<br />(SPR), and coating evaluations. The desktop
<br />review and assessment of the sanitary sewer
<br />pipe conditions are per the NASSCO standards.
<br />Also, performed were soil resistivity testing
<br />through evaluations for corrosive impact
<br />potentials the native soil may have on buried
<br />metallic components. We delivered a technical
<br />report detailing the results of the condition
<br />assessment findings and recommendations for
<br />improvements, including recommendations for
<br />preventive maintenance and rehabilitation using
<br />qualitative and quantitative data obtained during
<br />the assessments.
<br />Santa Clara Valley Water District Cross Valley
<br />Pipeline and Calero Pipeline Inspection and
<br />Rehabilitation Project. Morgan Hill, CA
<br />Project engineer for the inspection and
<br />rehabilitation of approximately 11 miles of 78-
<br />inch prestressed concrete cylinder pipe. The
<br />purpose of the project was to inspect the raw
<br />water transmission pipeline to determine if
<br />repairs were needed, rehabilitate various
<br />appurtenance vault sites, and install an acoustic
<br />fiber optic (AFO) monitoring system on the
<br />pipeline. Specific responsibilities included the
<br />planning and coordination of lockout-tagout,
<br />pipeline dewatering, AFO monitoring system
<br />installation, the electromagnetic and visual
<br />inspection, and the carbon fiber reinforced
<br />polymer (CFRP) repair method. [2018]
<br />Santa Clara Valley Water District Cl
<br />Levee/Access Road Repair. Morgan Hill, CA
<br />Project manager for the replacement of seven
<br />culverts that are embedded in the Calaveras
<br />Fault levee/access road, which allow water to
<br />pass through the levee without impounding. Due
<br />to degrading and aged infrastructure, the
<br />corrugated metal culverts would be replaced with
<br />HDPE pipe. Specific responsibilities included
<br />developing design drawings, acquiring
<br />environmental permits, determining material
<br />a
<br />quantities, and developing a cost estimate and
<br />schedule. [2018]
<br />Santa Clara Valley dater District Penitencia
<br />Water Treatment Plant Expansion Joint
<br />Replacement. San Jose, CA
<br />Project manager for the replacement of a 66-inch
<br />seismic joint located on a transition riser at the
<br />District's water treatment plant. The existing
<br />joint was leaking due to corrosion at the flange -
<br />bellow connection. Specific responsibilities
<br />included performing an on -site field assessment
<br />of the failure, preparing design specifications for
<br />a new joint, procuring materials, coordinating
<br />repair work, and developing a root -cause analysis
<br />report. [2018]
<br />Santa Clara Valley Water District Cross Valley
<br />Pipeline Inspection. Morgan Hill, CA
<br />Project manager for the electromagnetic and
<br />visual inspection of approximately 3 miles of a
<br />78-inch raw water pipeline. The purpose of the
<br />inspection was to assess the condition of the
<br />prestressed concrete cylinder pipe (PCCP) and
<br />determine if any repairs were needed. Specific
<br />responsibilities included developing a dewatering
<br />plan, coordinating lockout-tagout and dewatering
<br />operations, acquiring environmental permits,
<br />developing an inspection plan, coordinating with
<br />external consultants for confined space rescue
<br />support and electromagnetic inspection services,
<br />and performing the visual inspection. [2018]
<br />Santa Clara Valley Water District South County
<br />Recycled Water Pipeline Project. Gilroy, CA
<br />Project engineer for the design of 13,000 linear
<br />feet of 36-inch HDPE recycled water pipeline,
<br />which included multiple jack and bore crossings,
<br />a creek crossing using horizontal directional
<br />drilling, and air release and blow -off
<br />appurtenances. The pipeline began at the sewer
<br />treatment facility and ran through various
<br />farmland, public roads, and land developments
<br />in Gilroy. Project success required coordination
<br />with Caltrans, Department of Fish and Game,
<br />State Water Quality Control Board, City of Gilroy,
<br />County of Santa Clara, and the South County
<br />Regional Wastewater Authority. Design elements
<br />included materials evaluation, multiplejack and
<br />bore crossings, a horizontal directional drill
<br />crossing, flow control facilities, air release and
<br />blow -off structures. [2015]
