(San Francisco) Crushing concrete walls and masonry blocks may be uninteresting, but the Department of Public Works (DPW) Construction Management team for the recently completed Juvenile Justice Center showed that environment-friendly construction practices benefit the public and pocketbooks. 8,000 tons of concrete debris was diverted from landfills, and over $100,000 in dumping fees was saved.

Recognizing that having thousands of trucks haul debris of the old Juvenile Hall to a landfill near Half Moon Bay was not desirable, the project team decided during the demolition phase to bring in concrete crushing equipment and form a reclamation yard. Steel was separated from the mostly concrete building material and was hauled to an off-site steel mill for recycling. The concrete, however, was pulverized on site and piled for reuse.

The recycled concrete became aggregate base for the parking lots and roadways that surrounds the new Juvenile Justice Center. The crushed concrete was also used to backfill utility trenches. Remaining recycled concrete will be used on future projects.

 This was a win-win situation for everybody, said Joe Cheung, Deputy Chief of DPW's Bureau of Construction Management.  The public won't be burdened with more landfills. Taxpayers' money was saved. Since the contractor owns the debris from his demolition work, the contractor can make some money by selling the remaining recycled concrete to other ventures.

DPW Resident Engineer Albert Ko added that  by recycling the concrete on site, we also eliminated pollutants generated by trucks because hundreds of vehicles would have been needed to haul off the demolition debris and hundreds more would have been hired to bring in new building material.

The 90,000 square foot Juvenile Justice Center was opened last November and replaced an outdated facility that was built in 1950. The new building provides 110 sleeping rooms, with a capacity of up to 150 beds, and program space for educational, health care, food, and religious services. Outdoor recreation facilities will be completed later this year.

The construction cost of the new Center is $40 million.

The general contractor for the project is S.J. Amoroso.

Starting last July, private and public project contractors in the city were required to send their construction waste to a certified facility for reclamation and recycling, instead of straight to a landfill.
