Trenchless Design Services

Brierley Associates is a recognized national authority in the application, design, management, forensic analysis and implementation of trenchless technologies for underground infrastructure rehabilitation and new installation. The benefits of trenchless technology have been increasingly acknowledged as an economical and environmentally friendly alternative to conventional cut and cover construction. Aside from reducing disruption and damage to developed urban areas, woodlands, waterways and rural property, trenchless methods can dramatically reduce the carbon foot print of an underground utility corridor project.

Design of a successful trenchless project is much more than showing two boring locations on a site plan connected by a line. The process can be a complex mixture of client needs, contractual preferences, risk allocation, third party requirements, design criteria, surface terrain and geologic conditions. We draw upon our collective national and international “Creating Space Underground” experience to understand those challenges and deliver a successful project.
