Project: Construction Material Recovery Facility
Client: Del Webb
Location: Lincoln, CA
Highlights:
- $7,300,000
- Purchased debris sorting equipment used for the WTC disaster in New York
- Recycled 84.5% of debris from the construction of 6,500 homes
- Turned 36 million pounds of waste lumber into fuel for co-generation plants and generated enough clean electricity to power 1,500 homes for a year
Del Webb�s Sun City Lincoln Hills project required construction debris clean-up for 6,500 homes in Lincoln, CA. Construction sites typically accumulate
debris in front of each house which is periodically picked up and hauled off to local landfills. But Two Rivers Demolition developed an innovative solution.
Our President traveled to New York and purchased the mechanized system that was used to sort through the debris generated from the collapse of The World
Trade Center towers. By screening and sorting the debris, we diverted 84.5% of the construction debris from the local landfill.
In addition to the lumber, each month we recovered, processed, and baled 40 to 50 tons of cardboard, 20 to 40 tons of metal, plus tons of sheet plastic,
paper, and California Redemption Value (CRV) cans and bottles. Over the course of the project, we also recovered more than 5,000 tons of dirt-type fines
for golf course sculpting and alternative daily cover at landfills. We believe that this was the largest single-project material recovery facility in the
country.

- Recycled 99.4% of all materials
- Six-story concrete building with a footprint encompassing an entire city block
- Building demolition completed in 8 days
- 20,000 tons of concrete recycled on-site into Cal-Trans Class II Base Rock
- 1,200 tons of iron recycled
- 500 tons of trees and green waste recycled
Project: Chauvet Hotel
Client: Chauvet Hotel & Development Company, LLC
Location: Glen Ellen, CA
Highlights:
- Preserved a four-story earthquake-damaged building thought to be a total loss
When the roof of the Chavet Hotel collapsed after a small tremor, Two Rivers Demolition was brought in to handle the demolition. Built in 1913 by Jack
London, the building held significant sentimental value to the small vineyard community. Using live feed digital calipers and lasers to measure movement of
cracks in the walls and to monitor shifts in the building, the project team was able to carefully remove the roof debris that rested on the building�s
fourth floor.
The force of the roof collapse pushed one of the building�s exterior walls out and it was initially believed that the wall building would have to be
completely demolished. But Two Rivers Demolition conducted careful analysis and discovered that the wall was actually still completely in tact and needed
only to be shifted back in to place�which we were also able to accomplish. We performed all engineering and installation of shoring for every floor of the
building and bracing at all four exterior walls on the fourth floor.
Averting disaster, the owners were then able to convert the building into multi-million dollar lofts resulting in a successful project.
Project: East Ridge Mall
Client: VCC Contracting / Galleria Development
Location: San Jose, CA
Highlights:
- $1.5 Million Project
- Recycled 65,000 tons of concrete
- Recycled 1,100 tons of iron
This multi-story shopping mall required extensive demolition work for a major redevelopment project. Two Rivers Demolition gutted three-quarters of the
two-story mall, removing 125,000 square feet of interior concrete slab and 58,000 square feet of structural mezzanine. We were also responsible for the
engineering to preserve the existing columns until the structural retrofits could be installed.
The project also required demolition of a 52,000 square foot ice rink and a four-story department store building. We were able to recycle 65,000 tons of .
concrete into Cal-trans Class II base rock.
Project: Work/Live Lofts
Client: Hauser Architects
Location: San Francisco, CAA
Highlights:
This pair of two-story concrete warehouses that were built in the 1930s, required an extensive interior strip-out. Two Rivers Demolition completely gutted
all interior walls and ceilings. We also removed the entire concrete roof, all second story columns and beams, 25% of the concrete floor on the second level
and 100% of the concrete floor on the first level.
In addition, we made large openings throughout all exterior walls and performed mass excavation of 2,000 cubic yards of hazardous soils to make way for a
new basement garage. We performed all engineering for bracing and shoring of the existing structures.
Project: The Tuesday Club
Client: Sutter Hospital
Location, Sacramento, CA
Highlights:
- Diverted 3,000 cubic yards of demolition debris from the landfill
- Shredded the building�s wood components to produce fuel for a local cogeneration electricity plant
- Prevented damage to nearby church with $5 million stained glass windows
This historic four-story, 11,000 square foot building presented demolition challenges due to its proximity to another historic building: a church with
expansive stained glass windows imported from Rome and insured for $5 million.
Two Rivers engineered unique protective solutions and demolition approach in order to safeguard the church. Since the hotel was built with wood stick
construction, the original plan called for 52 high-side end-dump loads of building debris to be sent to a local landfill. But Two Rivers Demolition found a
better solution. We had the 314 tons of wood ground into chips and sold to a cogeneration plant. Rather than filling up the landfill, the wood fuel generated
enough energy to power 7,500 homes for a day.
Other debris from the site was also recycled including 84 tons of metal and 1,000 tons of concrete that was crushed onsite and used for backfill material.
The remaining debris left just five dump loads for the landfill, a substantial decrease from the original plan that called for 52 loads.
