California, United States - Safely and successfully decommissioning, decontaminating and demolishing a 241-station, 5,000-acre Cold War-era manufacturing plant is a significant challenge. When that plant is a former rocket propellant facility, with explosive materials that must be cleaned from a wide range of equipment, the risk is daunting.

Achieving the unachievable
Arcadis assumed liability for every aspect of this highly complex and hazardous project and served as General Contractor/Construction Manager, using a large and diverse team of subcontractors and self-performing construction crews. We successfully closed the site while maintaining full compliance with the requirements of 11 regulatory agencies and meeting an accelerated schedule that many believed unachievable — all while implementing a world-class safety management system.
By effectively combining cutting-edge technology, technical skill and discipline, and effective program and health & safety management, we worked with our client to overcome unique and intensive hazards and demonstrated that systematic risk management works.
Overcoming extreme site hazards
This was in no way a normal demolition project. Few outside the Arcadis team believed it could be done. We developed a comprehensive risk-based and nearly surgical approach tailored to the unique and extreme site hazards. We developed and employed innovative methods to assess and mitigate the risks associated with explosive residues in site structures and inaccessible spaces, and designed and implemented customized deconstruction techniques to keep our people safe.
Creating habitat through innovative site restoration
Recognizing the unique and sensitive nature of the site — home to rare plants and threatened and endangered species — our team designed and implemented a comprehensive remediation program that pioneered the development of new cleanup criteria for site soils, groundwater and surface waters. We also created innovative site restoration features, including ponds and streams, more than 100 acres of upland grassland habitat, and a first-of-its-kind bat habitat via conversion of a former three-story-deep basement into a thriving bat cave. The site is currently being marketed for sale.
