Project Layout

Standard Design and Construction Guidelines for Microtunneling Committee


Microtunneling projects should be laid out with attention to the benefits and constraints unique to this construction process. The following recommendations address some of these concerns: Minimize the number of pipe diameters; Construct microtunneling drives in both directions from a jacking shaft, when possible; Optimize drive lengths consistent with pipe size, pipe material, type of MTBM system used, and geotechnical conditions; Evaluate different depths, pipe sizes, and gradients; Optimize alignment.
