Like most cities across the U.S., the City of Tulsa is dealing with the maintenance and operation of an aging sanitary sewer infrastructure. One facet of the aging infrastructure of significant concern is the City’s vast array of large diameter concrete sanitary sewer interceptors. The City was quickly finding it difficult to determine the remaining lifespan of a concrete interceptor from traditional close-circuit television (CCTV) methods alone. This is when they reached out to RJN Group, Inc. for assistance with advanced pipe inspection technologies and RJN’s knowledge of utilizing these technologies to determine the Remaining Useful Life (RUL) of each section of concrete interceptor.… Read the restContinue reading
At this point, you are probably very familiar with RJN’s capabilities when it comes to wastewater services, including condition assessments like manhole inspections, smoke testing, dyed water flooding, and building inspections as well as flow monitoring, hydraulic modeling, master planning, SSES, and remediation and design. What you might not know is that RJN can apply our impressive skill set and use of advanced technologies to stormwater systems as well.
For example, over the last three years, RJN has been using advanced technologies to map and assess the condition of the City of San Antonio’s stormwater collection system with stellar results led by RJN’s Stormwater Lead and Project Manager Noelle Gaspard, P.E., GISP, CFM.… Read the restContinue reading
These days, it has become much more important to be proactive with underground infrastructure maintenance as opposed to reactive. Ultimately, it saves time and money to take preventive measures as opposed to fixing issues as they arise. One of the ways RJN is able to do this is by effectively using risk analytics to determine the best course of action for its clients.
Recently, RJN worked with the City of Richardson, Texas, to support its ongoing CMOM and master planning efforts by conducting a risk-based sewer study. The program focused on evaluating existing CCTV footage, identifying hydraulic capacity issues, and assessing the risk of asset failure.… Read the restContinue reading
At RJN, we always stay abreast of the latest technologies in the industry. If there is a new technology available that can make our field investigation techniques more efficient, accurate, and cost-effective, then we will definitely pursue it by either acquiring it ourselves or collaborating with contractors who possess the new technology. In both cases, be it RJN or a contractor with whom RJN is working, the teams responsible for using the latest technology will be experts with it, able to maximize that technology’s capabilities.
But having access to the latest technologies and being trained on how best to use those technologies is not enough—experts like the engineers and technicians at RJN also need to exercise good judgment, strong strategies, and creative problem-solving to decide when using these new technologies would be most beneficial to our clients.… Read the restContinue reading
RJN Group, Inc. has yet another option for manhole inspection in its growing portfolio of evaluative tools: It is called Panoramo SI, offered by IBAK, and it proves to be very helpful due to its technologically advanced capabilities.
As RJN rolled out this IBAK camera for manhole inspections in Fort Smith, Arkansas, crews quickly became familiar with the easy-to-use scanning system while building speed and production numbers. On the office side, manhole images coming in for coding are extremely clear and detailed, allowing office staff to quickly provide accurate NASSCO MACP, Level 2 inspections to the client. Soon RJN will be expanding usage of this technology to other upcoming projects, including Jefferson, Arkansas, and COSA stormwater (City of San Antonio, Texas).… Read the restContinue reading
RJN Group, Inc., has added a new technology to its impressive portfolio of evaluation tools. The new technology is BEM (Broadband Electro-Magnetic) pipe thickness scanning, and it has already proven itself to be a huge benefit to RJN’s team and a major value-add for clients. BEM technology again positions RJN at the forefront of innovative and sustainable collection system engineering solutions.… Read the rest Continue reading
