Buildings are one with the rock in the Spanish town of Setenil De Las Bodegas

I had never heard of this town before seeing the post on Setenil de las Bodegas is a small town of about 3,000 people in the Spanish province of Cadiz. The town is built within the narrow gorge cut by the Rio Trejo. Some of the buildings in the town are built into caves and beneath rock overhangs making this a very dramatic, and exotic European town! [Source: More info at Image: La Pantera via Wikimedia]

LIDAR Helps Locate New England Archaeological Sites PDF Print E-mail

LIDAR imagery from New England archaeological sites

One of the advantages of LIDAR topography data is the ability to "see through" vegetation so to speak. The light beams aren't actually seeing through physical objects, but because of the high density of LIDAR pixels, some of the beams in a vegetated area see through the canopy to the ground surface. The vegetation can then be screened out of the data using post-processing. This kind of "bare earth" imagery was recently used by archaeologists in New England to locate "lost" settlements that dated back to the 18th century.

Similar in the way that people who know wine understand terroir, or how the earth and geology influences the nature of wine, Beer is influenced by the geology as well! This is a really neat little article that I saw mentioned in the AEG Insider. Did you know that areas with softer water typically produce lagers and darker ales, and those with harder, more mineral-rich water are more conducive to paler, hoppier ales? I'll drink to that. Cheers! [Source: Check out this important Beer article in EARTH Magazine! via AEG Insider]

Attempting to Remove the Pipe Blocking Bertha PDF Print E-mail

Infographic on measures used by STP to remove the steel well casing blocking the Bertha TBM

The Seattle Tunnel Partners JV is attempting to remove the rest of an 8 inch diameter steel well casing that has been blocking the Bertha tunnel boring machine since December 8, 2013. The upper 55 feet was removed earlier, but another 64 feet or so remains in the ground in front of the cutter face.

The team is using a drilled shaft rig to drill 5 foot diameter shafts directly in front of the TBM face to attempt to intersect the steel. The first two shafts were completed last week. The first one did not strike steel, I'm not sure about the second one. I believe they have two more to go. The shafts will be backfilled with concrete to help form a protective wall in case workers need to enter the excavation chamber just behind the cutter face. If the steel is encountered in the shafts, they will attempt to remove it using augers or clamshell buckets. The DOT press release seems to indicate that there may be more what's blocking Bertha than just the well casing. We'll keep you posted. [Source: The Seattle Times.

Pittsburgh, PA – January, 7, 2014 – Nicholson Construction was recently awarded a $72.1 million dollar Design-Build contract to replace an existing force main from the Virginia Key Central District Wastewater Treatment Plant (CDWWTP) under Biscayne Bay Norris Cut to Fisher Island.

The project, which involves changing out the current 54-inch sewer force main for a 60-inch replacement, is set to last approximately 26 months. The main scope includes the installation of a precast concrete segmental tunnel, which will stretch more than a mile from the treatment plant on Virginia Key to Fisher Island.

8 Inch Well Casing Stops Bertha TBM PDF Print E-mail

Steel pipe blocking Bertha's cutterhead

WSDOT held a press conference on Friday to discuss findings regarding the obstruction that had stalled the Bertha Tunnel Boring Machine since December 6. It is an 8 inch well casing, 119 feet deep from a 2002 groundwater investigation associated with the tunnel project. Crews were finally able to dewater the TBM face enough to get a look last week.

The interesting part is that the TBM struck the casing on December 3, three days before it stopped. The rotation of the cutterhead lifted the casing 5 to 7 feet out of the ground. Crews removed the upper 55 feet of casing and thought that was the end of it. There were fragments of boulder on the conveyor belt, and crews felt they were dealing with a large boulder problem. So what now? The WSDOT officials were not specific, but likely Seattle Tunnel Partners crews will need to perform an intervention outside of the cutter face to remove the pipe and inspect for any damage to the cutterhead. The cost of the issue will count against a $40 million risk allowance for repairs and inspections near the front of the rotary cutting face — plus a $105 million general contingency fund. The overall tunnel project budget is $2 billion.
