Brierley Associates is an internationally recognized authority in the selection, design, construction management, forensic analysis of trenchless technologies. Our range of engineering and consulting services include new installations and pipe rehabilitation. The benefits of trenchless technologies 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 locales, environmentally sensitive areas,waterways and surface transportation corridors and airports; trenchless methods can dramatically reduce the carbon foot print of sewer, water and utility projects.
Design of a successful trenchless project is much more than drawing a line on a plan. The process commonly requires a detailed consideration of client needs, contractual preferences, risk allocation, third party requirements, pipe design criteria, surface terrain and alignment specific subsurface conditions. In each case,we draw upon our collective national and international “Creating Space Underground” experience to understand those challenges and deliver a successful project.
