Construction Testing and Laboratory Services
Our services do not end with site evaluation and design. Complete quality control testing and inspection services are also available during grading and construction. LOR's technicians are trained to provide testing and field observation services on a wide variety of projects. Behind each field technician is the support of professional engineers and geologists to provide timely on-site solutions to construction problems if they arise. All of our field and laboratory technicians are Caltrans and ACI certified. Construction testing and laboratory services are listed below:
Site grading control
Construction inspections of public infrastructure improvements
Batch plant inspections
Compaction testing services
