Development update for BOF meeting – 14 June

2005

Slide 2

Outline• main projects

– discussed in detail• smaller projects/collaborative

networks/ watching brief• trade bodies/liaison groups• recent finishes• proposals under consideration• what are you doing?

Slide 3

Main Projects

• EU– Sustainable Bridges

• CIRIA– arch bridge manual– tunnel manual

• Advanced composites– joint venture

Slide 4

Sustainable Bridges

• “Assessment for future traffic needs and longer lives”

• Integrated Project funded through EU 6th Framework programme - €10m project, €7m from EU, 32 partners from all over Europe.

• Response to EU objective of a 30% increase in rail passenger traffic & tripling of rail freight in 30 years

Slide 5

CIRIA Arch Manual (1)• title not finalised – currently “Masonry arch

bridges: management appraisal and remedial treatment”

• in same series as current CIRIA publications on embankments and cuttings

• cost about £150K (including in kind), cash funding from DfT through Roads Liaison Group & Bridges Board and from Network Rail

• ideally it will be “all you ever wanted to know about arches, but were afraid to ask”

Slide 6

CIRIA Arch Manual (2)• research contractor

– Mott Macdonald, supported by Prof Clive Melbourne (Salford University), Nisar Sawar (Birse Rail) and Carlos Sicilia (WK Ltd)

• steering group– about 20 people from all parts of industry

• final draft being circulated for comment• publication later this year

– electronic and hard copy

Slide 7

CIRIA Tunnel Manual (1)

• following on from arch manual• total cost also about £150K, funding

from more individual sources – including Network Rail

• research contractor– Mott Macdonald, supported by Prof

Chris Clayton (Southampton University) and Kevin Roberts (Atkins/Trans4m)

Slide 8

CIRIA Tunnel Manual (2)

• steering group about 10 people, including Colin Sims

• first draft recently circulated– still very rough and ready– second draft due May 2005

• publication expected early 2006

Slide 9

Advanced composites• Exclusivity of MouchelParkman/TGP

joint venture under review– possible that two further consultancies

(also working as a joint venture) will be approved

• CETAN being reviewed– issue 3 expected soon

• Autumn road shows– nominations needed from TCE organisation

Slide 10

Smaller projects (1)• CIRIA

– manual on the use of rock in hydraulic engineering

– whole life asset management across industries

• DTI– TSET (LSBU)

– MMS 6 (OBU)

– ACLAIM (AEAT)

– monitoring of concrete structures (CIRIA)

– specification for concrete durability (BRE)

Slide 11

Smaller projects (2)• Mining related (with JS)

– NDE for detecting mine shafts– monitoring and treatment of shallow

mine workings– updated specification for procurement

of mining related NDE

Slide 12

Smaller projects (3)• Universities

– Bath• shear assessment/strengthening of older pre-

stressed concrete beams

– Cardiff • usage cost drivers for masonry arch bridges

– Glamorgan• infra-red thermography for detecting faults in FRP

– Keele• non destructive evaluation of reinforced concrete

Slide 13

Smaller projects (4)• Universities (cont)

– Salford• soil/structure interaction in arch bridges

– Southampton• wrought iron characterisation for FRP

strengthening

– Surrey• FRP patch repairs for fatigue enhancement • residual fatigue life in elderly wrought iron

bridges

Slide 14

Collaborative Networks• European

• UK– SIMoNET– SMART Net– NGCC

Slide 15

Trade Bodies• CIRIA• Concrete Society

– Institute of Corrosion liaison

• Concrete Centre• Concrete Bridge Development Group

– fast construction task group– strengthening task group

• Steel Construction Institute– steel piling group– steel bridge group

Slide 16

Liaison Groups• Bridge Owner’s Forum

– mainly research focussed, but looks at some policy issues

• Bridges Board – Policy advice to DfT re highway bridges

• Bridgeguard 3– CSS– LoBEG

Slide 17

Watching brief (1)• Highways Agency

– additional parts for BA86 (NDE manual)– review of BA79 – management of sub

standard bridges– replacement of BD52/TD19 - road restraint

systems– parapet sector scheme

• BSI– Committee B/509/1

Slide 18

Watching brief (2)• British Board of Agrèment

– NTC17 – bridge expansion joints– HAPAS SG13 - scheme for composites

approval – Level crossing panels

• DfT Bridges Board– bridge management code of practice– performance indicators for highway bridges

• TWI– CSWIP accreditation scheme for composites

application

Slide 19
