21、l addition, improvements in best practices and technology continue to evolve so quickly that consideration of these guidelines in connection with any project must take into account not only the specific characteristics of the particular project but also further improvements in best practices and tec

22、hnology.These design and construction guidelines for microtunneling have been created by a group of engineers, owners, contractors, suppliers, and manufacturers working over the past several years. The changes to these microtunneling guidelines take into account many of the advances that have occurr

23、ed since their original publication in 200null null number of new sections have been added. nullny of the enullsting sections have been updated because of changes in technology as well as changes in construc-tion that make microtunneling a more acceptable means of construction.nullctions have also b
