Trenchless Technology Magazine Names Kimley-Horn Among Top 50 Trenchless Engineering Firms

Trenchless Engineering Kmimley-Horn

Kimley-Horn was named among Trenchless Technology’s Top 50 Trenchless Engineering Firms. The Top 50 Trenchless Engineering Firms list recognizes firms that have increased project revenue over the previous year by using trenchless engineering relative to total company revenue, the number of employees in trenchless design, and number of trenchless projects completed in the past year.

What is Trenchless Engineering?

This style of engineering refers to construction techniques for installing or rehabilitating underground infrastructure with minimal disruption to the surface, including traffic, business, and residential engineering projects. Trenchless methods include tunneling, microtunneling, horizontal directional drilling, jack and bore, pipe bursting, cured-in-place pipe, sliplining, and geopolymer or epoxy linings.

Kimley-Horn’s Water/Wastewater professionals have completed more than 230 miles of pipeline design using these trenchless technology methods across the U.S. Some of our noteworthy trenchless projects include:

  • Dallas Water Utilities Southside Interceptor Rehabilitation, which involves 11,600 linear feet of 120-inch wastewater interceptor rehabilitation using sliplining. The existing reinforced concrete pipe was designed to be sliplined with 110-inch fiberglass pipe. The project was designed with 11 access shafts with depths up to 50 feet and includes the rehabilitation of a 54-inch and 42-inch main with cured-in-place pipe.
  • San Antonio Water System Wastewater Interceptor, which includes 6 miles of 104-inch, 78-inch and 60-inch wastewater interceptor that was designed to be constructed by tunneling within TXDOT right-of-way following the roadway alignment at depths of up to 140 feet. The tunnel diameter will be up to 144 inches and the project was designed with seven proposed access shafts and a construction schedule of 3 years.
  • Miami-Dade Water and Sewer Department Raw Water Main Design, which involves the design of approximately 8,800 feet of 72-inch raw water pipeline through a heavily urbanized section of the City. The project included the implementation of a trenchless technology (micro-tunneling) for approximately 1,300 feet under two major canals and a major railroad switch yard.
  • Subaqueous Force Main Crossing (Horizontal Directional Drill), West Palm Beach, FL, which includes design, permitting, and construction administration of a 12″ high density polyethylene (HDPE) subaqueous force main which crossed the City of West Palm Beach’s water supply canal. The force main was encased with an 18-inch HDPE pipe with a leak detection system to ensure early warning in the event of a main break.
