Competence and professionalism over the years

Technology in many areas has experienced significant change, while in other areas older technologies remain part of our investigation best practices. The volume and level of detail of data and the speed at which data can be captured has increased exponentially. T2 Utility Engineers’ focus on SUE and related services means that they realize how important it is to continue to invest in acquiring the right technology and training for people, retaining the reputation of providing reliable, accurate information and advice, nevertheless, planning to stay a leader in our industry. Experience does matter in a SUE provider.  

Here’s to the next 30 years and beyond!

Origins of SUE

The growth and development of T2 Utility Engineers corresponds quite nicely with the development of Subsurface Utility Engineering in the United States. The Federal Highway Administration, which strongly supports the use of SUE, has an extensive history on their website - SUE Then and Now. Being responsible for Federal roadway and highway funding and construction guidance, the FHWA recognized that the common approaches to dealing with utilities surrounding highway projects in the 1980s were not working. The basic approach was to deal with utilities during construction. Imagine doing that now.

By the late 1980s a few states’ highway engineers were beginning to use geophysics and vacuum excavation to learn more about subsurface utilities to minimize disruption to the roadways and buried infrastructure. No more digging with a shovel or backhoe. The Virginia Department of Transportation (DOT), Maryland DOT, Delaware and Pennsylvania DOT began requesting subsurface investigations. SUE started to evolve as the interest and awareness of the value of SUE investigations grew and continues to grow to this day.

In 1995, the FHWA and ASCE requested the development of Standards to present a system of classifying data and  a consistent process for Subsurface Utility Engineering across the US. Started in 1995 and published in 2002, the ASCE 38-02 Standard was launched. Several members of T2 Utility Engineers’ team were active contributors in developing that Standard.  They have their continued engagement supporting the industry Standards through our membership on the ASCE UESI Standards Committee, which is responsible for updating the Standard, including the recent update -  ASCE 38-22.

T2 Utility Engineers’ major infrastructure projects have included SUE and Utility Coordination work as part of the multi-year rail transportation project on the Washington Dulles Airport, and the Gordie Howe International Bridge Design-Build, a $5.7 billion design-build P3 project consisting of a 1.5-mile cable-stayed bridge and border crossing across the Detroit River and to connect Detroit, Michigan in the United States and Windsor, Ontario in Canada.

In December 2021, through the integration of Intega into Kiwa, T2 Utility Engineers  became part of the Kiwa Group, joining the team operating in Australia, the United States, Canada and New Zealand, with the Kiwa Group  Dutch headquarters, which proudly includes more than 1,900 employees across 100 offices.

The next chapter of the T2 Utility Engineers story has begun with the recent  acquisition of Applied Professional Services (APS), a leading provider of utility locating services in Washington and Oregon, USA. The company provides a suite of utility locating services, including utility designating, vacuum excavation, Ground Penetrating Radar (GPR), and video pipe inspection services (CCTV). APS will continue to provide those services as well as supporting the expansion of T2 Utility Engineers’ Subsurface Utility Engineering (SUE) services in the US Pacific Northwest region.

T2 Utility Engineers strives to be a trusted advisor by providing unparalleled service, the most reliable information, and sound advice based on our professional experience. Their priority is to add value to each project they are privileged to work on, looking forward to the next decades.
