Key experience

KEY COMPETENCIES

Bridge construction, concrete technology. and quality assurance including:

(a) surveillance and quality auditing (bridge construction procedures, processes and products, (particularly for monitoring of special processes) and contractor performance);

(b) technical advice (concrete mix design, supply and placement of concrete, construction and inspection of concrete structures, and special requirements for durability in marine and other severe environments);

(c) review of contract documents (drawings, specifications, tenders and quality plans and documented procedures); and

(d) preparation of guide documents (specifications and documented procedures).

KEY QUALIFICATIONS (Major Elements of Experience & Skills)

40 years of concentrated experience in bridge construction, (and related design/inspection/contract management matters), including:-

(a) 4 years as Works Engineer managing large scale expressway bridgeworks by day labour, (with hands-on training in concreting operations under skilled foremen and tradesmen)

(b) 3 years as Resident Engineer supervising contract for The Rip Bridge (one of the most complex post-tensioned concrete bridge structures ever built.)

(c) 6 years as Supervising Engineer in Divisional Offices, responsible for all aspects of bridgeworks from design proposals to maintenance of bridge assets.

(d) 10 years in various management positions with responsibility for services of concrete and steel inspectors in off-site sub-contract works and on-site supervision of post-tensioning and associated concreting activities

(e) 10 years in the RTA's senior bridge construction technical advisory role, (during transition of contract management from QC to QA), but with little power to reform contract management policy and procedures. (For proposed reforms see referenced AUSTROADS Paper 1994 for early initiatives – then Osaka Paper 2002 – and finally fib Bulletin 44 – February, 2008) 

(f) In-depth experience in almost all types and phases of reinforced and prestressed concrete bridge construction practice as well as general experience in steel fabrication, erection and protective treatment.

(g) Extensive experience in site supervision and administration of bridge contracts (including major sub-contracts) and specialising in problem-solving.

(h) Developed ability to recognise potential construction problems in design details, construction specifications and Contractors’ quality plan procedures.

(i) In-depth knowledge of behaviour and properties of fresh and hardened concrete including durability and use of supplementary cementitious materials.

(j).(Following six years of semi-retirement ) Full time on site experience as independent verifier (structures) on major DCM Alliance type contract involving heavy reinforced concrete and diaphragm wall construction and covering range of duties including concrete mix design approvals, examining of work procedures, technical audits and site inspections and supervision including some training and mentoring of younger engineers and workmen.

Representative Major Projects

Some representative major bridges where I had operational or supervisory responsibility include the following

    Sydney-Newcastle Expressway – (Direct control construction by the DMR of NSW)  a wide variety of expressway structures including pretensioned and post-tensioned girders, reinforced box girders, post tensioned voided slab and composite steel and reinforced concrete

    The Rip Bridge – (Contractor John Holland) a unique post-tensioned concrete balanced cantilever, where each cantilever was a concrete truss – with temporary deflections controlled by provision of temporary hinges, flat jacks and a sophisticated stressing system which allowed selective de-stressing and re-stressing of tendons

    Bridge over Nepean River at Maldon (Contractor John Holland) first post-tensioned box girder bridge in NSW (segmental cast in situ)

    Bridge over Shoalhaven River at Nowra (Contractor Codelfa) Precast segmental post-tensioned box girder

    Bridge over Wingecarribee River (steel box girder superstructure)  engineering supervision of welding supervisors on shop and field welding operations

    Tunnel under Gold Coast Airport on Tugun Bypass Project (Diaphragm wall construction in saturated ground followed by heavy reinforced concrete slab construction for roof and floor)

Valuable Indirect Experience

Two major disasters powerfully, although indirectly, contributed to my experience: 

(a) (Melbourne, Australia, 1970) Collapse during construction of Westgate Bridge steel box girder span - 35 men killed – some survivors worked with me on The Rip – subsequent Report of Royal Commission is damning but illuminating – still relevant to all civil engineers responsible for design and construction

(b) (Stavanger, Norway, 1990) Sleipner A – post-tensioned offshore drilling platform support structure imploded during trial sinking operations - no one injured – I spent four days with senior QA engineer on construction six months prior to collapse – subsequent enquiries vindicated construction QA but not design –eventually led to demise of Norwegian Contractors (NC) –

 

Despite failure, construction QA by NC had established a world benchmark - construction problems were identified and solved before construction started – concreting problems were resolved as an integrated exercise involving reinforcement detailing, formwork and stressing system constraints (See Article by Jan Moksnes.)
