Arroyo Grande High School
Student Support and Multipurpose Rooms,
Arroyo Grande, California

The Student Support and Multipurpose Rooms are approximately 11,000 and 13,000 square feet respectively, and are single-story with conventional continuous and spread foundations as well as concrete slabs-on-grade.  They are of masonry, structural steel, and stud construction.  The new structures replace the previous Administration/Multi-Use building.  The project also involved landscaping and exterior pedestrian walkways composed of Portland cement and asphalt concrete. 
 
Earth Systems Pacific performed a soils engineering investigation entailing site reconnaissance, subsurface exploration, laboratory testing, and geotechnical engineering evaluation of the data collected.  Preliminary geotechnical recommendations were provided to guide the development of project plans and specifications.  Construction began in November of 2006 and was completed in 2009. 
 
Our technicians and inspectors performed compaction testing, certifications of grading and backfill operations, concrete sampling and testing, and inspection of masonry, structural steel, and epoxy anchor bolts.
