Work Group H
Innovative uses & replacing concrete structures, e.g. abutments, wind farm, gravity structures
Steve Cross - Royal Haskoning
Robin Dawson - DCP
Duncan Nicholson - Arup
John Hull - SPUK
This Workgroup combined two previous ones which was “Areas where steel could replace
concrete” and “Innovative uses”
The majority of this report will be photographs or details from drawings with some text. The group
will also give some equivalent costs and structural details to justify the proposals.
In no particular order of merit we list some obvious uses that might be considered innovative
which might be defined as “A use which some Engineers might not consider”.
1. Bridges like Whaddon Road Bridge in Milton Keynes DCP built using box piles as one
section foundations and columns
2. Abutments using sheet piles and also approach ramps to tunnels
3. Storm water tanks. Bedford, Chelmsford and Heathfield STW. Appropriate coatings and
clutch sealing methods.
4. Basements and underground car parks
5. High Modulus walls are rarely used in the UK compared to Holland and Germany. Combi
walls are more normal. AM HZ AZ system installed with push pull system for inner city
basement walls to compete with diaphragm walls
6. Super span gantries with box piles and precast beams, not in situ like the M4 M5, with a
concrete plug and reinforcement plug steel with simple shear connectors.
7. H piles on road bridges. Duncan mentioned a design programme called Piglet has
contributed to this by designing out lateral loads which concrete piles are less able to resist.
8. Jacked foundation piles in in London in water bearing gravels and chalks instead of bentonite
9. Piles in contaminated ground
10. Retaining walls in soft rocks less than 5 Mpa where pre-auguring now possible
11. Soil nailing using H piles and sheet piles
