Using a TBM is also much less labor intensive than mining or cut and cover construction so with labor costs as cut and cover tunnels Second Ave Sagas
Cut and cover method of tunnel construction is generally used to build shallow tunnels In this method a trench is cut in the soil and it is covered by some support which can be capable of bearing load on it
This is different than most subway construction today which involves boring tunnels for the tracks while digging the stations out in the open cut and cover To avoid street disruption the Second Avenue Subway s stations took much longer to build than if the MTA had used cut and cover

· The subway extension s skyrocketing costs and delayed report trace back to the same cause A mid study realization that the preferred construction method of digging a deep trench building the subway tunnel and then burying it — known as cut and cover — was no longer feasible
Road tunnel construction is subject to underground uncertainties and risks and as such it is difficult to predict the final construction cost especially at the conception phase where issues are evaluated and important design decisions are made A system assisting in the early cost estimation of
T he conventional subway construction approach attempts to reduce these impacts by using two smaller TBM s to construct the trackways in separate running tunnels between stations but this method still requires cut and cover methods to construct the stations For the subway planned in San Jose using cut and cover techniques would require
A tunnel s construction method is determined by several factors including geology cost and potential disruption of other activities Different methods may be used on individual tunnels that are part of the same larger project for example four separate methods are being used on portions of Boston s Central Artery/Tunnel project
