Geocon provided as-needed geotechnical engineering, observation and testing, and special inspection and materials testing services for the Riverside Unified School District for new construction and modernization projects throughout the district.  

Riverside Poly High School Campus Quad area  

Geocon performed a geotechnical investigation and provided a geohazard report in accordance with CGS Note 48 requirements.  Geocon also provided geotechnical observation, special inspection, and materials testing during construction improvements. The purpose of the geotechnical investigation was to evaluate subsurface soil and geologic conditions in the area of proposed construction, and based on conditions encountered, to provide conclusions and recommendations pertaining to the geotechnical aspects of design and construction. 

Riverside Polytechnic High School was constructed in 1964 and needed modernization and updates to bring the entire quad area up to ADA standards, replace and repair existing utilities, add shade and areas for the students to comingle, and upgrade the student entrance from the parking area for safety reasons as well as ease of access. The quad improvements at Poly High included new concrete ramps and walkways throughout the campus, underground infrastructure upgrades, two new shade structures, upgraded amphitheater area, new student entry portal, and ADA upgrades. 

Geocon provided special inspection of structural welding and bolting, concrete placement, and masonry construction to document the construction was performed in accordance with the project plans and specifications and DSA requirements.  

Riverside Poly High School Auxiliary Gym 

Geocon performed a geotechnical investigation and provided a geohazard study for the Poly High School’s auxiliary gym improvements in accordance with CGS Note 48. The building is a recreational gym consisting of a main court area with bleachers, and several rooms and restrooms. Additional improvements included paved access areas, hardscape, and utility improvements.  

The purpose of the investigation was to evaluate subsurface soil and geologic conditions in the area of proposed construction, and based on conditions encountered, to provide conclusions and recommendations pertaining to the geotechnical aspects of design and construction in accordance with DSA requirements. 

Geocon provided geotechnical observation and testing, and special inspection and materials testing services during construction of the improvements for the Poly High School auxiliary gym. 

Several shallow utilities were encountered during earthwork which prevented the remedial grading from being performed in those areas.  Geocon was immediately responsive, providing recommendations for slurry encasement of the exiting utilities which avoided the utility relocation and enabled the remedial grading to be performed.
