State support: yes, Virginia, C&D recycling can save money.

Faced with crowded landfills, high construction costs and environmental concerns, cities and states across the nation are recycling recycling, the process of recovering and reusing waste products—from household use, manufacturing, agriculture, and business—and thereby reducing their burden on the environment.  construction debris and implementing other Green Building practices, while trying to minimize cost and timing barriers. Virginia is now among those states.

 Complex and is leading the Commonwealth of Virginia's efforts in demolition, recycling and construction by tapping into Green Building techniques with the building of a new parking structure.

Green Building practices incorporate environmental sensitivities in the design and construction of new structures by recycling and reusing materials and making new structures energy efficient.


In the fall of 2003, the sounds of bulldozers roared through the air as contractors working for DGS began demolishing two abandoned buildings, the former Division of Consolidated Laboratory Services building and the former Motor Fuel Lab, both located at the corner of Fourteenth and Bank Streets in downtown Richmond, Va.

"Before we started the project we met with the construction contractor to convey to him and his staff the importance of the recycling program," says Chinh Vu, DGS Manager for Security and Special Projects. "This is the first time the scat of government has taken on a recycling effort of this size and we wanted to make sure we had the commitment from everyone involved to make this work," Vu says.

As in most urban areas, parking is scarce for government employees and visitors to government facilities located in the central business district. Since the buildings located at the corner of Fourteenth and Bank Streets had outlived their useful life and there was a pressing need to replace parking spaces that were being lost, this site was viewed as being an ideal location for a new parking deck.

The project provided an opportunity to implement, for Virginia, a radically different approach incorporating an aggressive effort to recycle re·cy·cle

The demolition of these two buildings yielded almost 14,000 tons (28 million pounds) of asphalt asphalt (ăs`fôlt, –fălt), brownish-black substance used commonly in road making, roofing, and waterproofing.

The fate of the concrete was markedly different. A concrete Crusher was set-up onsite to recycle 100 percent of the concrete, which amounted to 12,750 tons of the total amount of material generated. The crushed concrete was used as backfill back·fill

. This considerable recycling effort, the first of its kind in the Commonwealth, resulted in a savings of more than $485,000. This is a conservative savings estimate because it does not include the cost of labor. Including the labor costs to haul material away could increase the savings to more than $500,000.

Expenditures in a typical demolition and construction project under the conventional approach include transportation to the landfill, disposal charges, buying backfill materials, and paying for the transportation of these backfill materials to the site. The estimated cost to do this at the Laboratory Services site was almost $590,000.

Calculating the cost of recycling the concrete onsite includes expenditures for equipment, such as the concrete crusher, excavator ex·ca·va·tor

A comparison of the methods demonstrates that if the conventional method of demolition and construction were used, costs would have been upwards of $590,000, while the aggressive recycling approach utilized by DGS cost less than $100,000. Recycling these materials did not affect the overall project schedule.

"Government should lead by example," says Richard Sliwoski, Director of Engineering and Buildings. "This project clearly-demonstrates that states can recycle construction materials, build a project in a timely manner, safeguard the environment and save money."


Prior planning was critical in ensuring that recycling activities did not cause contractors to deviate from the project timetable.

This project was not the typical low bid job, but rather was procured under an approach known as Construction Manager at Risk. Companies bidding on the project were required to include recycling processes into their proposals mid develop a timetable for sorting, recycling and project completion. Other options reducing the demolition time were explored, including implosion implosion /im·plo·sion/ (im-plo´zhun) see flooding.

During the four-month demolition period, the debris was removed from the basement area and all materials were sorted into appropriate piles piles: see hemorrhoids.  and recycled. Now well underway, the new $19 million parking structure is an example of a new approach to traditional construction methods.

"Everyone always asks us what lessons we learned," Sliwoski said. "We knew this was possible and we proved it can be done in a timely, cost-effective manner if it's built into the project plan. Instead of waiting for laws to catch-up and require recycling of construction materials the state is leading by example. Yes, Virginia, you can save money through recycling."
