Faced with field and construction projects requiring the collection of large amounts of data, documentation of conditions and progress, and the simultaneous participation of engineering, scientific, and technical staff, E2 set out to develop a method to streamline the myriad activities required by complex projects. The result is E2 M2M®, a proprietary iPad application that facilitates data collection and sharing, resulting in efficiency and transparency on important projects. Using E2 M2M®, data can be input; forms can be completed; and photographs, reports, and documents can be uploaded to a secure server that can be accessed in real-time by those with proper access credentials. The level of access granted to each individual can be customized.

Multiple field teams use E2 M2M® concurrently, logging information on iPads such as boring logs, field notes, water levels, site pictures, videos, inspection reports, chains-of-custody, and daily operations logs. As additional needs are identified by its users, E2 M2M® is adapted by adding fields and functionality to address those needs. Time spent completing field logs and project documentation was reduced immediately by 75 percent on the first projects for which E2 M2M® was used. Additionally, the accuracy of information has been improved as field staff input data once and are no longer required to transcribe handwritten field data and notes to the computer hours after the event. QC checks can be created and customized for data input fields offering an initial level of data quality screening, also contributing to accuracy.



E2 M2M® can be customized to meet the requirements of any project that includes the collection of field data. E2 M2M® is streamlining and adding transparency to projects that include:

  • Water infrastructure—inspecting and documenting sanitary and storm sewer conditions
  • Construction—inspecting, documenting, and managing environmental and general construction
  • Storm water—inspecting and documenting compliance with construction storm water permits or facility storm water permits
  • Energy utility infrastructure—inspecting, documenting and collecting data for gas pipelines
  • Environmental or compliance monitoring—groundwater, construction, surface water, air, geologic exploration, well installation, soil sampling, vapor intrusion, and more
  • Ecological surveys—documenting and recording the presence and location of species of concern



E2 has developed a method to safely and effectively detect and locate pipeline leaks. By using a pair of remotely operated, mechanical pressure isolation tools in the form of pipeline pigs, the team is able to isolate the location of a leak in a pipe wall. The tool, called an isolation pig, was developed to provide pressure isolation as a prelude to excavating and replacing sections of pipeline and finding leaks during hydrotests.

With a keen understanding of the challenges of identifying the location of a leak in a long stretch of pipeline, E2’s pipeline experts saw an innovative new use for this tool. By anchoring one isolation pig using a specially designed set of grips in a known location beyond the leak, a second isolation pig is progressively moved at predetermined intervals within the pipeline. The second isolation pig is used at intervals of, for example, 100 feet along a length of pipeline. The second pig is then anchored in place. The pressure within the pipeline is increased to verify on which side of the isolation pig the leak lays. By monitoring the pressure within the pipeline, the presence of a leak can be detected in the limited, isolated length of pipeline.
