Friends Quaker Meeting House, 6 Mount Street, Manchester, M2 5NS

The 49th Cooling Prize
Competition will be held Manchester on 28 February 2018.

The Cooling Prize is
held annually to celebrate the life of the late Dr Leonard Cooling, chairman of
the British Geotechnical Society Committee (forerunner of today's BGA), to
encourage young ground engineers to hone their technical paper-writing and oral
presentation skills.

At the event the three
finalists will present their papers:

• Christopher Krechowiecki-Shaw (University of Birmingham): Using traffic as a
  low-cost treatment for temporary heavy haul loads
• Joseph Newhouse (Mott MacDonald): Ground movement due to shaft construction
• Alexandra Clarà Saracho (University of Cambridge): Microbially induced calcite precipitation
  (MICP) to mitigate contact erosion in earth embankment dams

The judging panel will
be Arup’s Francesc Mirada, who won the 2017 event, Manchester University’s
Domenico Lombardo, Bolton University’s Paul McMahon and BGA chairman Martin
Preene.

After the presentations,
while the judges consider their verdict, a short keynote lecture will be given
by Andrew Smith of Coffey on:

Major Repair Works on the A645 Newland Bridge

Newland Bridge is a
3-span steel composite structure carrying the A645 over the River Aire between
Drax and Goole.

Since construction
in 1992, the approach embankments have suffered up to 800mm of settlement,
causing abutments to displace, damaging bearings, closing movement joints and
introducing a large propping force into the bridge deck. If unresolved, the
continued settlement could cause further significant if not catastrophic damage
to the bridge.

The solution adopted was
to replace the upper portion of the approach embankments with “Leca”
light-weight fill, thus virtually eliminating future settlement. The damage to the bridge could then be
repaired, enabling the structure to achieve its remaining design life.

The presentation
describes the problems experienced by the bridge and the methods adopted to
design the remedial works.
