Nicholson Completes Emergency Work on Indiana’s I-65

Nicholson Construction stabilizes pier on I-65 using micropiles and low-mobility groutingPITTSBURGH, PA – Nicholson Construction recently completed emergency repair work to an unstable pier supporting a bridge on INDOT’s Interstate 65. These repairs enabled a 37-mile section of the highway’s northbound lanes to be reopened after a four-week closure.

The highway was in the process of being rehabilitated and widened when the pier was damaged by steel piles driven into the water tight ground below it. The pier began to settle and eventually rotated ten inches.

Nicholson developed a design-build solution that used micropiles to transfer the loads to more stable soils and low-mobility grouting to fill voids and densify the upper subsurface layer.

“The natural artesian groundwater conditions were instrumental in causing the problem and posed the biggest challenge in developing the fix,” said Rick Deschamps, Vice President of Engineering. “The design-build approach developed was geared towards minimizing the risk of additional damage to the pier, while providing a safe and timely solution.”

Because of the emergency nature of the job, the Nicholson team had to mobilize to the site quickly, install test piles and install the piles within three days to fix the settlement issues. In addition, the coring of the footing and low mobility grouting below the pier foundation were also completed.

“The use of micropiles allowed a deep foundation to be installed within the artesian conditions of the site and overhead constraints of the existing bridge,” said Aaron Evans, Area Manager for Nicholson’s Chicago Office. “The closure of I-65 was obviously a major issue, and we are pleased to have been a part of developing the solution to reopen the interstate.”
Work for this phase of the I-65 project is scheduled to be completed in Spring 2016.

Federal Highway Administration Launches New National Tunnel Inspection Program

United States of America Department of Transportation New Initiative Modeled After Longstanding Bridge Program

WASHINGTON –The U.S. Department of Transportation’s Federal Highway Administration (FHWA) today published the final rule for national tunnel inspection standards that will serve as the foundation of the nation’s first standardized tunnel inspection program. It will be modeled after the FHWA’s successful bridge program established nearly a half-century ago to ensure the safety of the nation’s bridges.

“This important step to keep our nation’s tunnels safe for the traveling public is unprecedented,” said U.S. Transportation Secretary Anthony Foxx. “Establishing national standards will help us maintain a high level of quality and uniformity in tunnel inspections nationwide.”

Up until now, FHWA has provided tunnel inspection guidance but had no means by which to require tunnel owners, such as state departments of transportation or other transportation agencies, to inspect tunnels. In addition, tunnel inspection methods have varied widely. With this new program, FHWA will compile an inventory of the nation’s tunnels and begin to develop a national database similar to the National Bridge Inventory (NBI).

The new standards, referred to as National Tunnel Inspection Standards (NTIS), are modeled after the National Bridge Inspection Standards (NBIS) currently used to ensure the inspection of bridges throughout the country. The NTIS include similar inspection requirements and annual reports of tunnel condition information and inspection findings. The requirements will include routine inspections of tunnels on all public roads along with written reports to FHWA, training and a national certification program for tunnel inspectors, and the timely correction of any deficiencies with tunnels.

“Just like bridges, each tunnel is structurally unique and requires dedicated attention and uniform measurement standards,” said Acting Federal Highway Administrator Gregory Nadeau. “The new Standards will ensure inspections are consistent and focused to help ensure the public’s safety.”

To support the implementation of the Standards, FHWA has developed several guidance documents and manuals. The agency will offer training to state and local engineers on how to conduct highway tunnel inspections, including on what elements to inspect and how to code and record the results.

The final rule can be viewed at https://www.federalregister.gov/articles/2015/07/14/2015-16896/national-tunnel-inspection-standards.

Nortex and TerraThane Stabilize Houston Area Highways

Houston’s Highways, Some of Busiest in Nation, Use Innovative TerraThane Polyurethane Foam Technology to Repair Bad Bridge Approaches, Uneven Joints, and Roadway Depressions.

Nortex employees stabilizing Houston area freeway with TerraThane Polyurethane Foam

MOUNT AIRY, NC—Highways around Houston, TX, known as one the nation’s worst cities for traffic behind Los Angeles, D.C., and Atlanta, need constant repair, but can’t be closed while the work is done. Nortex Concrete Lift and Stabilization, Inc., a Ft. Worth, TX company, recently completed a whirlwind repair project on one of the city’s busiest corridors in the NE quadrant where I-10, 610 Loop, I-59, and I-69 feed millions of cars daily to, from, and around Harris County.

Normal groundwater erosion beneath the highways causes the concrete highway slabs to drop, roadway depressions, uneven bridge approaches, and uneven joints that make driving bumpy and uncomfortable, dangerous, and causes severe wear and tear on automobiles.

To make the repairs, the Texas Department of Transportation, TXDOT, brought in Nortex. The company carefully planned out the repairs for the half million pound project, and sent out four crews each with it’s own box truck rig to use a relatively new technology called “foamjacking.” Foamjacking uses high-density polyurethane foam to fill the subterranean voids, and lift the concrete slabs to proper level. “We’ve been lifting and stabilizing roadways with polyurethane foam since we got into the business back in 2003,” says Casey Derosa, asst. gen. mgr. of Nortex. “It’s a far superior method versus the old way of mudjacking.” Mudjacking is a ubiquitous term for a mix of mud, sand, cement, crushed limestone, and water hydraulically pumped into large holes drilled into the concrete slabs to fill voids and level the slabs. Mudjacking uses more and much larger equipment, and requires larger holes to be drilled. It typically requires the roadway to be closed much longer than foamjacking, and takes more time to clean up.

According to Derosa, Nortex started in January working to complete the 150 plus location project. They went about standard operations by drilling 5/8-inch holes in the concrete slabs and pumping TerraThane polyurethane foam made by the US company, NCFI Polyurethanes, into the voids, filling then lifting the slabs to proper level. On some locations the slabs were lifted as much as eight inches to ensure the highway was level and a smooth driving surface.

Nortex employees stabilizing Houston area freeway with TerraThane Polyurethane Foam“We worked at night closing two-to-three lanes of the five-to-six lane highways to try to keep traffic moving and cause as little inconvenience as we could,” says Derosa. “We used our large gang drills with attached towable air compressors to drill the small holes then followed behind with the pumping equipment to deliver about 10,000 pounds of TerraThane foam per night. It was done over such a wide geographic scale—Conroe and The Woodlands down to Galveston County—it was not uncommon for the project manager to drive 100 miles a night overseeing the crews.”

Derosa says he used TerraThane because they’ve worked with NCFI Polyurethanes’ Geotechnical Division on formulations since 2003. “We love the specialized TerraThane material. It’s a four-pound foam system with very high compression strength, ideal cell structure, and low tolerance for water absorption. Day in and day out, it’s consistently the best product on the market.” Derosa points out that the State of Louisiana, with which they often work, requires geotechnical polyurethane foam be tested every 20,000 pounds pumped, and says TerraThane has “never failed the test for density, compression strength, and cell structure. Not once.”

When asked what advantage TerraThane gives Nortex over other products, Derosa says, “It’s why we’re able to do more with less poundage. State DOTs are looking for products that meet or exceed expectations and this product certainly does that. We never worry when we use TerraThane. We trust the consistency and quality of each set we buy and use. NCFI has proven to be a great partner in this growing business.

“TXDOT is pleased with our operation, and the repairs. They couldn’t have asked for a better solution, or product to do the highly specialized job.”

Introducing the LS™250 MiniSonic™, a Versatile Compact Sonic Rig

Introducing the LS(TM)250 MiniSonic(TM), a compact sonic rig for a wide variety of environmental, geotechnical, water and mining projects.SALT LAKE CITY, April 13, 2015 /PRNewswire/ — Boart Longyear (www.BoartLongyear.com), the world’s leading provider of integrated drilling services and drilling products, is proud to introduce the LS™250 MiniSonic™, a compact rig suitable for a wide variety of environmental, geotechnical, water and mining projects.

Capable of drilling to depths of up to 250 feet (78m) when used with 4.75 inch (121mm) casing, the wide 600mm rubber tracks provide low ground pressure (.28 bar/4psi) and make it perfect for jobs in the most sensitive and fragile terrains. Plus, its smaller footprint makes it appropriate for projects with small drill pads, environmentally sensitive areas or hard-to-reach sites and requires less support equipment – making it a low-cost solution for a variety of mining, environmental, geotechnical and infrastructure drilling projects.

"Boart Longyear has had this sonic head in the field for 10 years, and its reliability is unmatched," said Greg Guillot, Senior Product Manager for Capital Equipment. "That means more uptime and drilling hours between head maintenance, which results in lower operating costs and higher productivity."

The LS250 MiniSonic rig offers several distinct advantages over conventional rigs. It provides a relatively undisturbed core sample of unparalleled quality and accuracy through any type of formation, with minimal deviation. When using the iso-flow groundwater profiling system, hydrogeological and geochemical data can be easily obtained. Additionally, drilling with the LS250 MiniSonic reduces waste by up to 80 percent. Sonic drilling is faster than conventional overburden drilling methods and greatly reduces the risk of project failure due to unknown or difficult subsurface conditions.

Safety features of the rig include an interlocked rotation barrier, reduced noise levels, a dump mast and wiggle tail, and a rod presenter. The interlocked rotation barrier automatically slows head rotation when the barrier is open. The LS250 MiniSonic provides lower noise levels when equipped with the Tier 4i engine package.

The LS250 MiniSonic’s articulated mast and wiggle tail enables the mast to shift from left to right and front to back to position the mast precisely over the hole, eliminating time-consuming rig movements. The dump mast allows the crew to work from the ground, enhancing safety by avoiding stairs and safety rails often required when working from a platform.

The innovative rod presenter allows the rod and casing to be loaded horizontally, with an actuator that then presents the rod and casing vertically to the head. The head rotates 28 degrees to the side for sample extraction, while the head slide shift allows for unobstructed winch use down the hole.

The LS250 MiniSonic is the ideal rig for a wide variety of soft ground, shallow drilling projects, including environmental, tunnelling, water management, grade control and leach pads. Faster penetration, nearly undisturbed samples using little or no fluids and its casing advancement system make the LS250 MiniSonic ideal for a variety of applications. The LS250 MiniSonic offers unmatched versatility and reliability for an outstanding value.

Aquadata – A Web Based Water Quality Public Portal

Aqua Data web portal EarthScience Information Systems (ESCIS) is pleased to announce the release of the Shoalhaven City Council Aqua Data website, a branding of the ESdat Public Portal.

Aqua Data is a web-portal providing greatly enhanced community access to the results of water quality monitoring completed by Shoalhaven City Council (SCC). Aqua Data is the public interface of a detailed system designed to streamline the way SCC manage and share environmental data.

Aqua Data is accessed via a link on the Shoalhaven City Council web site directing users to the Aqua Data home page


The Aqua Data home page features a map interface with water sampling locations clearly displayed on a familiar Google Maps background. Clicking on a water sampling location within the map generates tables and graphs of water quality data for that location. The tables and graphs can then be downloaded and printed.

Aqua Data provides a free and easy to use portal for the community to access up-to-date water quality data.

Key benefits include:

  • Increased visibility and accessibility of important community information
  • Freeing up SCC resources, previously dedicated to responding to community requests for water quality information

Greg Howarth, the SCC Project Manager, explains how Aqua Data will benefit the community?

“Aqua Data has been designed to improve the sharing of water quality monitoring results with the community and to assist consideration of water quality data within the catchment planning and catchment management decision making process.”

The benefits of the new system extend beyond the public portal. Behind the scenes the new system developed by EScIS completely upgrades the way SCC manage water quality data. EScIS have implemented ESdat Online as the framework to allow SCC staff to import, review and approve laboratory testing results. The approved results then automatically appear on Aqua Data.

ESdat Online uses a web-browser interface, allowing SCC staff to rapidly compile and compare historical results with new data as soon as it is received. SCC now have greatly enhanced ability to assess water quality, identify any potential hazards and trigger a suitable response. Greg Howarth, the SCC Project Manager again:

“ESdat Online will save Council time and resources that we can now spend serving our customers”

EScIS have worked closely with ALS, who provide laboratory analytical services to SCC, to develop an efficient and robust system of transferring data from the laboratory into the SCC system as quickly as possible.

ALS have worked hard to successfully meet the critical technical requirements of the project to ensure a smooth transition for SCC as the new system is adopted.

Philip Kennedy, ALS Projects Coordinator:

”ALS realises the importance of providing accurate and timely data, particularly when related to public health.  The ALS IT team have modified system outputs to support the requirements of SCC and EScIS.  This exciting initiative demonstrates ALS’ capability and commitment to streamlining the data management processes and looks forward to working with ESCIS on further projects.”

SCC has extended the use of ESdat Online beyond the data presented in Aqua Data. SCC also use ESdat Online to centralise management of lab testing data associated with the day-to-day operations of important SCC infrastructure, such as water treatment facilities.

“The ability of the ESdat Online system to automatically email staff informing them that a reading is outside the expected range will be a great asset in assisting rapid responses to time critical issues.”

SCC and EScIS are excited by the positive changes in community engagement and SCC operations the Aqua Data and ESdat Online will deliver and are currently working together to map future expansion and development of the system.

Greg Howarth, SCC Project Manager:

“Shoalhaven City Council (SCC) are now keen to work with other water quality custodians to expand the use Aqua Data, so that the benefits of having a cost effective, one-stop, easily maintained and accessible water quality information service is shared and utilised by a growing audience”

Latest Release of HoleBASE SI Transforms Laboratory Scheduling

Lab Scheduling Press Release atmisRedditch 30th Jan 2015 – The new release of HoleBASE SI includes ‘scheduling tools’ that allow engineers to electronically schedule geotechnical or environmental testing. This major breakthrough is likely to transform the way consultants and laboratories communicate with each other over the coming months.

The new improvements also provide a glimpse of how well integrated customers and laboratories can be with the first UK wide implementation of a web service connection to ALcontrol’s @mis online laboratory data management system. . This unique development allows customers to schedule testing directly into the @mis system using data and tools inside of HoleBASE SI and then be notified within HoleBASE SI when the testing is completed.

“The new features in HoleBASE SI are going to change the way our clients and their laboratories work together” said Roger Chandler, Managing Director of Keynetix. “For years laboratory staff have been transferring test results using AGS data format but these new additions make it much easier for the engineer to schedule their testing within their data management system, significantly reducing transcription errors by laboratory data entry staff.”

Laboratories are able to send clients electronic schedule instructions, including the type of testing they offer and any additional requirements required for each test. This reduces the number of follow up calls the laboratory needs to complete to finalise the testing schedule.

Although AGS data is now commonly used as the data transfer format of choice by engineers and laboratories, there are often problems with all 4 AGS sample references being maintained and returned to the engineer. The addition of these features will significantly reduce occurrences of this problem.

Geotechnical laboratories are able to upload their schedule instructions to the Keynetix website, to give them immediate access to HoleBASE SI users around the world and promote their services to HoleBASE SI users.

Lab Scheduling Press Release HoleBASESIScheduling

In addition to these features the web service interface to ALcontrol’s @mis system allows the user to send electronic Chain of Custody information directly to the @mis system and then allows them to schedule their environmental testing requirements in @mis without leaving HoleBASE SI. By using this new technology HoleBASE SI is then able to tell the user when the testing has been completed and automatically download and import the results.

“This new web service is our first opportunity in the UK to directly interface @mis with a leading geotechnical/geoenvironmental data management system like HoleBASE SI, advancing capabilities we have already successfully deployed in mainland Europe” said Richard Hepburn, Managing Director of ALcontrol’s UK & Ireland Environmental Division. “With many man years of time in development @mis seamlessly wraps around our core Laboratory Information Management Systems (LIMS) and it has been refreshing through working on this project with Keynetix to see a shared mindset in terms of deploying technologies which simplifying the data management journey and reduce errors for customers”..

“The creation of the first AGS based web service with ALcontrol has given us an opportunity to show engineers and clients how data transfer will work in the future” said Gary Morin, Technical Director at Keynetix “The service shows what the new technology is capable of and being able to embrace these new techniques was one of the reasons we have upgraded the HoleBASE SI core technology over the last 4 years.”
