A lot of our telecommunications clients are surprised to learn we do much more than towers, just a brief sampling of some or our more interesting projects is below:
 |
SUPPORT OF EXCAVATION adjacent to the river, through 20-feet of soil, and 20-feet of rock, system consisted of secant piles, tieback, rock bolts, and shotcrete (contractor's design, not ours). We did borings, packer tests, and assisted GC. |
|
|
Sheeting & Shoring design for the new York County PA, Judicial Center (Courthouse), we used PYWALL to design the soldier piles and tiebacks. |
 |
UNDERPINNING/SUPPORT OF EXCAVATION Using soil nails and shotcrete, and existing wireless Telecommunications HUB building was underpinned 14-feet to allow for expansion |
|
|
Foundation modification existing tower in downtown Savannah Georgia, the challenge in this situation was to transfer load from leg to the new foundation, bypassing the overstressed anchor bolts. We worked very closely with Williams Form Engineering who provided pigtail anchors and huge eye bolts |
|
|
National Park Service, Fort Washington Here we used ground penetrating radar to scan the sides of the century old masonry to detect water damage. |
 |
Tie Down or Rock Anchor proof testing in the middle of nowhere, in the middle of winter. |
 |
Non Destructive Analysis of 1908 factory - Here we used radar to locate the "Kahn Method of Reinforced Concrete", then cored the floor, extracted samples, and had the yield strength determined. This was done in an operating candy bar factory. |
 |
In-Situ or Pressure Meter Testing for a parking garage in downtown Baltimore (Little Italy) - Here we used the pressure meter testing to validate to get much higher drilled shaft skin friction values than normal correlation to SPT would predict. |
|
|
Retaining Wall Analysis - This was 20 to 30 year old wall of unknown design or origin that was failing. |
 |
 Stealth Tower - The existing (1950) tower
was eventually surrounded by urban sprawl and it became advisable to
construct a stealth tower. |
 |
Light Pole Survey- A major mall owner had a series of light pole (50-ft) failures resulting is substantial property damage, but miracously, no injuries. Using a DM4-DL ultrasonic thickness gage with data logger, we survey 60 poles, getting 60+ reading per pole, and then compiled a risk analysis spreadsheet of the 4000 data points. |

Cantilevered sheet pile cofferdam (picture was taken before excavation), using PYWALL |

Routine geotechnical explorations in support of new mausoleum construction. |
