HomeServicesTrenchless Design

The design of a successful trenchless project is much more than drawing a line on a plan. The process often requires detailed consideration of surface terrain, alignment specific subsurface conditions, pipe design criteria, client needs, contractual preferences, risk allocation, and third-party interests. We draw upon our collective national and international experience to understand those challenges and deliver a successful project.

Brierley Associates is an internationally recognized authority in the selection, design, construction management, and forensic analysis of Horizontal Directional Drilling (HDD) and other trenchless technologies. Our engineering and consulting services include new installations and pipe rehabilitation. Trenchless design reduces disruption and damage to developed urban locales, environmentally sensitive areas, waterways, and surface transportation corridors and airports. Trenchless solutions can dramatically reduce the carbon footprint of sewer, water, and utility projects.
