| Project: |
Twin Peaks T.I. |
| Dates: |
July 29, 2009 to September 25, 2009 |
| Location: |
I-10 in Marana, AZ |
| Owner: |
Arizona Department Of Transportation |
| Contractor: |
Pulice Construction |
| Description: |
SSC was contracted by Pulice to complete 3 bores to install a total of 800' of 42" casing for a 24" in water line under Highway I-10 between Casa Grande and Tucson, AZ |
| Challenges: |
Maintaining line & grade |
| Method: |
Auger Bore |
| Results: |
Successfully completed bore to install 70' of 42" casing at 1st location. Successfully completed bore to install 175' of 42" casing at 2nd location. Third bore to be completed 4Q 09'. |
| Project: |
Sewer Line Upgrade Under SRP Canal |
| Dates: |
January 12, 2009 to January 26, 2009 |
| Location: |
SRP Canal at 71st Drive, Phoenix AZ |
| Owner: |
City of Phoenix |
| Contractor: |
Sundt Construction |
| Description: |
SSC was contracted by Sundt Construction to install 104-ft of 36-in casing for a new 12-in sewer line below the old SRP canal. |
| Challenges: |
Muddy soil conditions |
| Method: |
Auger Bore & Hand Tunnel |
| Results: |
Geotech reports 50-ft from the planned installation site at 71st Drive indicated sandy soil conditions, with a 8-9 blow count. However, crews quickly discovered mud during the first few feet of the bore, making it a challenge to maintain line and grade. Switching from auger to hand tunnel at the most dense locations, SSC was able to successfully complete the project in 1.5 weeks. |
  
| Project: |
Sewer Line Upgrades at 56th Street |
| Dates: |
February 7, 2008 to September 18, 2008 |
| Location: |
North of the 101 Freeway between 56th and 64th Streets, Phoenix, AZ |
| Owner: |
Meritage Homes Construction, Inc. |
| Contractor: |
DCS Contracting
Kimley Horn & Associates |
| Description: |
SSC provided consulting services to Kimley Horn & Assoc. for the design of on-site and off-site waterline infrastructures associated with a 270 acre mixed use development in north Phoenix. SSC provided pre-design potholing services to expose existing 42-in and 24-in waterlines. In addition to consulting and potholing services SSC was also awarded the sub-contract to install a 78-in casing for a diverted sewer line and a 36-in steel casing for a 12-n air jumper. |
| Challenges: |
Complex existing utility conflicts, that could not be taken out of service, made this one of the most unusual and technically challenging projects that SSC, DCS and Kimley-Horn had ever encountered. |
| Method: |
Auger Boring, Hand Tunnel |
| Results: |
Through close collaboration with the City of Phoenix Water Services Department, Arizona Department of Transportation (ADOT) and Specialized Services Company (SSC), Kimley-Horn designed an atypical but highly effective solution that split a 36-in sewer line into three 18-in lines at the point of conflict to allow for the transfer of flow below the existing 42-in & 24-in waterlines (with only 4-inches of separation). Two custom junction structures were also designed complete with internal diversion benches and air jumper. |

| Project: |
Hovensa Oil Refinery, US Virgin Islands |
| Dates: |
Oct 1, 2007 to Oct 19, 2007 |
| Location: |
St. Croix, US Virgin Islands |
| Owner: |
Hovensa, a joint venture between a subsidiary of Hess Corporation and a subsidiary of Petroleos de Venezuela, S.A. (PDVSA), operates one of the most modern refineries in the United States. With crude oil processing capacity of 700,000 barrels per day (BPD), Hovensa is one of the largest in the world. |
| Contractor: |
SSC |
| Description: |
The main refinery was constructed in the early 1960's, and sits atop a dredged ocean floor. Four of the original main lines, which pump crude oil from holding tanks to the main refinery, needed updating, requiring the installation of 4 new steel wall casings. |
| Challenges: |
Along the 120' bore path, 2 (48") steel casings & 2 (30") steel casings had to pass through at least six different soil types ranging from coral to sticky clay. This initially proved challenging for SSC because of the lack of binding materials in the soil to prevent cave-ins. |
| Method: |
Auger Bore |
| Results: |
With over 38 years of experience in all soil types SSC was able to overcome these challenges using time tested technology, finishing the project eight days early with line and grade intact. |
