The South Surrey
Interceptor collects sewage
from Surrey and Langley,
British Columbia, Canada,
and conveys it to Metro
Vancouver's Annacis Island
Wastewater Treatment
Plant. Phase two of the
interceptor project was
designed by Stantec and
installed by tunneling
using a highly successful
innovative design.
The result is new highways, byways,
subways, and passageways that are redefining transportation, waste removal, and
underground infrastructure.
"Particularly in urban areas, as near
surface underground real estate has been
used up by existing infrastructure, tunnel
solutions are being pushed deeper and
through more challenging geology," says
Colin Lawrence, global tunnels practice
leader at Mott MacDonald. "Tunneling
technology has had to meet an array of
new challenges."
Computer-aided design (CAD),
Building Information Modeling (BIM)
software, high-tech tunnel boring
machines (TBMs), and radical advances
in construction materials have made it
possible to tunnel farther and deeper than
ever before. Furthermore, it is now possible to build tunnels in subterranean places
where it was not possible in the past. As a
result, a new generation of underground
tunnels are taking shape.
"Tunnels are now being constructed
through conditions that would not have
been contemplated over 20 to 30 years
ago," Lawrence says.
How do engineering firms design and
build these structures, which can extend
to over 30 miles and pass through challenging geological ground conditions and
structures? How do firms mitigate risk
during construction and build tunnels that
can withstand a major earthquake or an
explosion and fire inside the tunnel? How
are firms using new materials to improve
visibility and safety inside tunnels?
"Tunnel engineering has become a
complex multidisciplinary field," says Paul
Guptill, senior principal at Kleinfelder.
"Today, it involves everything from geoscience to computer science and numerical
modeling."

Although the first human constructed tunnels appeared thousands of years ago-primarily as a way to transport water, people,
and equipment-the modern era of tunneling took shape in the late 1800s. Late
in the century underground construction
of the New York subways began. When
it commenced operation in 1904, the
subway represented a new and far more
advanced way to move people within a
crowded city. By 1927, the Holland Tun-
