Trenchless Technology Magazine Announces Its 2015 Top 50 Trenchless Design Firms

Trenchless Technology magazine, the leading publication covering the trenchless technology marketplace, has released its annual list of the Top 50 Trenchless Design Firms for 2015. This is the 19th year Trenchless Technology has conducted its annual survey ranking trenchless engineering companies in North America.

The rankings are based on reported North American trenchless project billings. Coming in at No. 1 in 2015 is Englewood, Colo.-based CH2M, which moved up from the No. 3 spot in 2014, reporting trenchless billings of more than $161 million over the last fiscal year.

Rounding out the Top 10 from No. 2 to No. 10 (in trenchless billings) are: Hatch Mott MacDonald ($149 million); AECOM ($102.4 million); Arcadis ($69.3 million); Stantec ($67.7 million); CDM Smith ($67.6 million); Black & Veatch Corp. ($66.3 million); Jacobs Engineering Group ($48.3 million); Cardno ($46.3 million) and Brown and Caldwell ($41 million).

In addition to trenchless billings, the survey asks participants to report total company billings, number of trenchless professionals working for the firm, the number of trenchless projects completed in the past five years, and finally, a breakdown of trenchless projects completed by method.

The Top 50’s collective trenchless billings total roughly $1.19 billion, a 4.8 percent increase from the collective Top 50 in 2014, showing a slight market gain in trenchless construction overall. However, the collective percentage of trenchless work by the Top 50 relative to total company billings came in at 2.9 percent – a slight decrease from 2014, suggesting a decline in trenchless design relative to engineering firms’ full scope of work. Collectively, the Top 50 reported 36,989-plus trenchless projects completed since 2009 – an increase from 2014. The project totals by breakdown in method revealed horizontal direction drilling (HDD), subsurface utility engineering (SSUE) and pipe rehabilitation remain the strongest markets.

Trenchless Technologys survey is aimed at providing readers a glimpse into just how much the trenchless design market continues to expand. Trenchless Technology wishes to thank everyone who participated in this year’s survey. For more information on how to participate, contact Trenchless Technology managing editor Sharon M. Bueno at

The complete Top 50 rankings for 2015 will be published in the December issue of the magazine (in print, online at and on the app for your iPad), along with some of the great projects completed by the Top 10 firms.
