Data Analysis With DCP

DCP (Dynamic Cone Penetration) Testing is a simple, reliable and cost-effective method to evaluate the in-situ stiffness profile of soil to a depth of about three feet. Its extreme portability, minimal disturbance of the subgrade, and ability to produce a continuous depth profile make it an ideal system for testing the mechanical properties of a pavement system during any stage of construction. The following simple equation is traditionally used to express the stiffness of a material from DCP test values: PR = Depth of Penetration / Number of Blows If you are new to DCP testing, you may be wondering whether the PR value can be used to calculate to other, more familiar geotechnical parameters, and whether DCP test results correlate well with those from other testing systems. Much has been researched and written on this subject, and the short answer is yes —DCP testing can easily and repeatably measure the same parameters as other in-situ and lab-based soil testing methods. For example, the California Bearing Ratio (CBR) test is another penetration test commonly used to measure the load bearing capacity of road beds. Perhaps you want to know the CBR values for a test site, but you have opted for a DCP system instead, due to its simplicity and lower cost. No problem! PR values can be converted to CBR values by applying a simple equation. This widely used conversion was developed by the U.S. Army Corps of Engineers and is used by many state DOTs and federal agencies: Log (CBR) = 2.465 - 1.12 Log (PR) This calculation and many others can be performed automatically by a state-of-the-art DCP setup. The Vertek SmartDCP kit can be operated and transported by a single user by hand, and provides instantaneous data collection and graphing capabilities via smartphone app. Data can [...]

Seismic Averaging in SCPTu testing

Did you know that our CPTSND Data Acquisition program can average repeat seismic strikes? Once you have a strike on the screen, simply accept (retain) the strike and then add another strike of the same type ( A strike for example). This second strike will display below the first strike and when the second strike is accepted (retained) it will be averaged with the first strike and only the averaged strike will remain on the screen. If a third strike is added and then accepted (retained) it will be averaged with the result of the first two. (NOTE: Our software does not retain all the individual strikes- once they are averaged only the average is on file) Averaging strikes is recommended by some of the top GeoTechs in the nation!

Karst sinkholes form when the bedrock of the Earth is slowly worn away by erosion.[SLIDESHOW: How karst sinkholes form]Under the top soil is a layer called the overburden. Under that is bedrock, which may seem tough and solid, but it's actually filled with cracks and crevices water is constantly seeping through and infiltrating. As the water erodes the bedrock, the overburden starts to fall down into the space left behind. Years later, all that's left is a thin layer and the potential for a sinkhole to open up.However, if there's a slab over the surface you may not know there's a problem until it's too late. That's why Matt Dettman developed MSEDS, short for Mechanical Sinkhole Early Detection System. Dettman is a WKU Associate Professor of Civil Engineering [...]

MSD budgets $200 million for Ohio River Tunnel project – WDRB 41 Louisville News

The Metropolitan Sewer District is budgeting $200 million for the Ohio River Tunnel project to improve water quality in Louisville. LOUISVILLE, Ky. (WDRB) – The Metropolitan Sewer District is budgeting $200 million for the Ohio River Tunnel project to improve water quality in Louisville. According to Jacob Mathis, an MSD engineer and manager of this project, just a tenth-of-an-inch of rain can overwhelm parts of the sewer system in the district, sending stormwater and drainage straight into the Ohio River or Beargrass Creek. “In a typical year, there’d be four billion gallons of sewage released into these waterways,” Mathis said. In hopes to reduce sewer drainage across the country, the federal government is requiring communities to find ways to mitigate the damage by Dec. 31, 2020. If Louisville does not meet the deadline, the government could enforce fines or penalties. In response, MSD engineers devised a plan of three new basins in three different neighborhoods to store overflow. But there were concerns over how much that could interrupt construction, business and daily life. MSD decided to take a different route and came up with the Ohio River Tunnel project. “This project is one of the first of its kind in Louisville or even the state of Kentucky,” Mathis said. Engineers describe it as being on the same level and magnitude as the Ohio River bridges undertaking. But this project is intended to be out of sight, out of mind. “There will be less disruption to the community itself with traffic impacts, economic impacts,” Mathis said. “We won’t disturb the big economic corridor along Main Street.” The tunnel will start underneath what will be the western part of Waterfront Park near 13th and Rowan Streets. It’ll head east underneath the Ohio River towards I-64. At the Second Street Bridge, the tunnel then jogs inland to Butchertown. [...]

Drilling in Southwest Indiana at a 15-year peak

Indiana State officials say Southwest Indiana is experiencing a boom in oil and gas exploration, with a peak number of wells drilled over the past 15 years. The Indiana Department of Natural Resources Division of Oil and Gas released a report earlier this week that says oil and gas wells are being drilled in Indiana "At a pace that hasn't been seen for at least 15 years," according to Herschel McDivitt, director of the DNR Division of Oil and Gas. DNR officials say the division issued more than 450 drilling permits in 2006, a number that McDivitt expects to steadily increase during the next several years, due to the anticipated higher prices for crude oil and natural gas. "This is an exciting time to be in the oil and gas business," McDivitt said in a press release announcing the news. "While much of the interest is in drilling for crude oil, a growing number of wells are being drilled for natural gas, especially in the southwestern part of Indiana where companies are actively developing wells." McDivitt acknowledged that along with the increase in drilling applications has come a significant number of questions from landowners who have been approached by companies seeking to obtain leases from the landowners allowing them to drill on their properties. "Many landowners are unfamiliar with the process of leasing their land for oil and gas and are seeking more information about oil and gas operations and looking to find answers to their questions," McDivitt said. DNR has also made some changes in the Division of Oil and Gas's organizational structure. Jim AmRhein will be responsible for all inspections and compliance- related functions within the division's program. Previously, AmRhein was in charge of all permitting functions, as well as inspections and enforcement duties in central and northern [...]

Upcoming Tunneling Projects – Tunnel

2/10/2016 Upcoming Tunneling Projects CALIFORNIA Laguna Beach Tunnel Stabilization and Sewer Pipeline Replacement Approved by the South Coast Water District Board of Directors in 2010 and the City of Laguna Beach in late 2013, the Tunnel Stabilization & Sewer Pipeline Replacement Project (Tunnel Project) is a 100-year solution to protect the environment, local economies and neighboring communities. The project comprises two key components: Tunnel Stabilization: The District will enlarge the size of the tunnel from an average of 6 to 9 ft. This will ensure safer working conditions and greater access for future pipeline maintenance and repair. Permanent shotcrete lining and steel supports will be installed at several locations where required, replacing rotten timber supports and removal of loose rock that currently exist. Pipeline Replacement: The District will install a new 24-in. pipeline throughout the tunnel. The current pipeline – also 24 in. in diameter – will be encased in concrete, but preserved for redundancy and emergency use. The cost to repair the tunnel is estimated at approximately $90 million and will be funded through low-interest state loans, grants and the District’s general fund. Shortlisted tunnel contractors announcement was anticipated for 2014-2015 with request for bids expected in 2015 and NTP in 2015-2016. Los Angeles The North East Interceptor Sewer (NEIS) Phase 2A The North East Interceptor Sewer (NEIS) Phase 2A project is currently the northern extension of the NEIS Phase 1 project. The project will construct approximately 3.03 miles of 8-ft diameter sewer in tunnel and associated structures. The sewer will be constructed from the Division St. Shaft site, near the intersection of San Fernando Road and Cazador Street and terminate at the northern overflow parking lot for the Pony and Train Rides in Griffith Park, just north of the I-5 Griffith Park On/Off Ramps (I-5 Shaft Site) east [...]

I-65 construction south of Indy tests commuters’ patience

Trips from Southport to southern Johnson County can take up to an hour longer Story Highlights More than $286M in road projects from Indy to Louisville on I-65 this summer. 20 motorists have died in accidents on I-65 this year Southside commuters are swerving, merging and yielding a lot for road construction this summer — and there’s little relief in sight. From Southport Road to Edinburgh and beyond, concrete testing barricades and orange traffic barrels on Interstate 65 have led drivers through myriad lane shifts and closures, adding precious time to rush-hour commutes, as the highway and bridges are rebuilt or repaired. Alternative routes, including portions of U.S. 31, also are being revamped. “There aren’t too many areas (of I-65) where we don’t have construction testing and inspection going on right now,” said Indiana Department of Transportation spokesman Harry Maginity. “If you are driving from Indianapolis to Louisville (Ky.), you are going to see a lot of it all year.” INDIANAPOLIS STAR I-65 NB lanes reopen in Lafayette area The biggest projects are on I-65 around Greenwood where about 63,000 cars travel both ways each day. Heavy machinery in the blocked-off medians and on bridges has made space in the travel lanes tight and twisting. Combined with reduced speeds, the journey in and out of Indianapolis can add more than hour of travel time for a trip between Southport and Edinburgh. “Our drivers plan that a trip from I-465 on the Southside to Edinburgh is going to be 45 minutes slower,” said Tim Piper, owner of Same Day Transportation, Indianapolis, which has 35 trucks. “If there’s an accident, it’s going to be even longer.” Overall, INDOT Construction Testing is doing three repair projects worth a combined $156 million on I-65 in the metro area. Four other projects to the Kentucky [...]
