I was informed by a Mr Mann, the project's chief engineer, that the cost

This is in an area of saturated dune sands, clays and silts with little
sedimetary rock and no hard rock - so tunnel lining performance parameters

Cue Bruce on how you must also be a profoundly ignorant ****wit as this
clearly is impossible. Obviously an extra 1.4m would raise the price so high
no one in their right mind could state the cost difference was negligable?

Isn't that right Mr Fantasy Tunnel Designer Bruce? (Though I suspect the
only "tunnel" he's ever been involved in building is making one out of
a rolled up newspaper)
