In addition to providing extensive services for large diameter tunnels, Jacobs Associates offers design, construction management, and consulting services for small diameter tunnels and trenchless technologies. Typical small diameter tunneling and trenchless construction methods may include: Microtunneling • Auger Boring • Pipe Jacking • Horizontal Directional Drilling • Pilot Tube Microtunneling • Pipe Bursting • Pipe Ramming • Hand Mining • Small Diameter Tunnel Boring Machines

Our experience ranges from the production of plans, specifications, and cost estimates for engineers, public utilities, and private sector owners to the design of initial support for contractors. Much of our small diameter tunneling and trenchless technology consulting is performed as specialty design and construction management to supplement other general civil engineering firms’ services. Jacobs Associates staff is recognized throughout the trenchless technology industry, making regular appearances as seminar faculty and publishing technical papers regarding the latest advances in this area of underground construction.

What sets us apart from our competitors?
As with our approach to conventional large diameter tunneling, Jacobs Associates trenchless technology specialists consider the interplay of the owner’s functional requirements with the construction processes and geotechnical conditions specific to each project. When difficult conditions dictate, we bring in our ‘mile deep’ resources, comprised of engineers with specialized education and practical experience in a variety of disciplines required for trenchless technologies. These disciplines include pipe engineering, geotechnical engineering, structural engineering, construction engineering, construction contracting, construction management, and construction disputes avoidance and resolution. Unlike other trenchless technology specialists, Jacobs Associates understands the full range of small diameter tunneling and trenchless technologies available to successfully complete the work.
