Tunnels About the Book. He’s a loner at school, his sister’s beyond bossy, and his mother watches TV all day long, but at least Will Burrows shares one hobby with his otherwise weird father: They’re both obsessed with archeological sites. An accurate determination of the ground condition ahead of a tunnel face is key to stable excavation of tunnels using a Tunnel Boring Machine (TBM).
