| Project: |
Clean up on Metro Light Rail Track |
| Dates: |
9-13-2008 to 9-13-2008 |
| Location: |
SSC crews worked over 12 hours consecutively to clear miles of track starting from the Central and McDowell Road intersection working south down 1st Avenue to Jefferson, then east to 26th Street and Washington. |
| Owner: |
City of Phoenix |
| Contractor: |
Archer Western Contractors |
| Description: |
SSC used their state-of-the art System 4000 to clear debris from track to allow Metro Light Rail to safely expand testing to the majority of its new line across the Valley. |
| Challenges: |
Two months after its initial introduction in downtown Phoenix, the Metro Light Rail began testing trains from Mesa through downtown to the intersection of Central and McDowel Road. Prior to testing however, miles of debris that had settled on the tracks during the three-year long construction process had to be cleared to avoid damage to the trains during the testing process. |
| Method: |
Vacuum Excavating |
| Results: |
If not for SSC and its unique fleet of System 4000 Vacuum Excavators, this might have been a much more difficult and time consuming process than one might think. With two Vacuum trucks in tow, SSC crews worked over 12 hours consecutively to clear 8 miles of track. With only one day remaining before testing was to commence, the crews did an amazing job that could never have been accomplished in time without the aid of the System 4000. |

| Project: |
Storm Drain Locating in Mesa, AZ |
| Dates: |
3-24-2008 to 3-25-2008 |
| Location: |

| Owner: |
City of Mesa |
| Contractor: |
ESI Contracting |
| Description: |
ESI contracted with SSC to expose an existing storm drain that was identified using reliable as-builts and an electronic locating device, 19 ft. below the surface. An area 15 ft. x 40 ft. wide x 15 ft. deep was excavated with a trackhoe to allow the vacuum to excavate the last 4 ft. and safely expose the storm drain. |
| Challenges: |
This was a challenging project for SSC as the buried storm drain was located so far from the Vacuum truck. |
| Method: |
Vacuum Excavation |
| Results: |
Vacuum excavation utilizes 95% air at a volume of 100+ PSI and 5% water to break up soil in record time. Using the powerful air-vacuum system allowed SSC to span the distance between the system and the excavation site and expose the utility as successfully as if it had been a routine potholing project. |
