Field Inspector, Rawlings Reservoir Repair and Replacement; Tustin, CA; City of Tustin (Completion: 2013; Value: $12.5 million) —Mr. Alonso performed construction inspection services for the replacement of the Rawlings Reservoir, which required 150,000 CY of grading. The City's former 4.0-million gallon hopper bottom reservoir was taken out of service due to its age and deteriorating condition. After its decommissioning, the City proceeded with the design of two 3.0-million gallon pre -stressed concrete (circular DYK-style) water storage tanks to replace the reservoir. Prior to bidding, Butier assisted the City with solving construction access and temporary shoring issues. The project originally required the construction of a tie -back retaining wall, which would have extended the project into an adjacent property. At the City's direction, Butier performed a constructability review and proposed using a cantilevered shoring system, which would keep the project within the City's property line. In addition, Butier assisted the City in obtaining a temporary construction easement from the adjacent landowner to the north. Use of this undeveloped property provided the Project team with an access road down to the bottom of the tank elevation, as well as laydown and stockpiling areas. Field Inspector, Santa Ana River Enhanced Recharge Phase 1A Sedimentation Basin and Pipeline; Highland, CA; San Bernardino Valley Municipal Water District (Completion: 11/2018; Value: $14.4 million) — The project site is located adjacent to the southern flank of the San Bernardino Mountains on the western side of a relatively large alluvial fan complex associated with the Santa Ana River.

The new sedimentation basin removes fine sand prior to delivery to Valley District or Metropolitan facilities. It is 200-foot wide and 600- foot long and 10 feet deep. The new pipeline consists of 1,900 linear feet of 96-inch diameter CMLC welded steel pipe and 1,300 linear feet of 78-inch diameter CMLC welded steel pipe connecting the new sedimentation basin and the existing 78-inch diameter SBVMWD Foothill Pipeline.
