Will You Still Need Me.. When I'm Sixty-Four? a Story of Ageing Bridges WILL YOU STILL NEED ME.. WHEN I’M SIXTY-FOUR? A STORY OF AGEING BRIDGES Dean Ferguson, General Manager, Infracorr Consulting Ian Godson, Director and Principal Engineer, Infracorr Consulting Scott Gleason, Materials Engineer, Infracorr Consulting INFRACORR COMPANY OVERVIEW Investigation and Condition Assessment Commissioning Design and and Ongoing Specification of Monitoring Repair Systems Infracorr Consulting Pty Ltd Construction Quality Durability Assurance Design Specialist Consultants in the Repair and Preservation of Infrastructure 2 BENEFITS OF EARLY INVESTIGATION OF REINFORCED CONCRETE STRUCTURES Level 1 & 2 bridge inspections provide only visual defects & cannot detect the early stages of reinforcement corrosion. Technical investigations provide: • Prediction of time to corrosion • Early detection of active corrosion • Ingress depth of contaminants (Carbonation & Chloride) • Early detection of ASR (Alkali, Aggregate Reaction) Early detection enables preventative strategies to be adopted providing significant savings 3 TYPICAL CONCRETE INVESTIGATION • Delamination survey • Chloride, carbonation, cement content • Resistivity testing • Electrical Continuity • Half cell potential mapping • Corrosion rate (time to spalling 4 EARLY INTERVENTION HOPKINS RIVER BRIDGE – OVERVIEW • 160 metre long coastal bridge • Prestressed trough beams, precast piles, insitu headstocks • Age 18 years • Visual Condition – Excellent Prestressed beams ~1.2m 5 above high water level HOPKINS RIVER BRIDGE One day investigation to prestressed beams found: • 30mm designed cover to ligatures (40mm to strand) • Critical chloride to depth of 25 to 28mm • No active corrosion, low corrosion rates (passive) • Predicted corrosion of ligatures and strand in 2-5 years 6 Prestressed trough beams had 30mm cover PRESTRESSED BEAMS IN MARINE CONDITIONS Prestressed “I” beams incorporating high strength strands • Strands corrode & pit quickly once critical chloride levels reached • Rapid brittle failure of strands & beams • Patch repair not possible due to stress & brittle strands • Strands cannot be welded or repaired • Can utilize CP with difficultly (Hydrogen embrittlement, lack of continuity) HOPKINS RIVER BRIDGE SOLUTION • Immediate treatment with chloride barrier coatings (silane) • Predicted delay in chloride activated corrosion, 35 – 40 years • Project budget $120,000 • If delayed ~5 years, CP based repair ~$2 million 8 MID–STAGE INTERVENTION TRAFALGAR PARK FOOTBRIDGE – OVERVIEW • Footbridge at Nelson. South Island New Zealand • Constructed 1996 (22 years old) • 63m single span, arch bridge • 2 Reinforced concrete arches, connected by 6 cross beams • Supported by reinforced concrete pile caps 9 TRAFALGAR PARK FOOTBRIDGE Chloride instigated corrosion in tidal splash areas including: • Lower arches • Pile caps • Lower two cross tie beams 10 TRAFALGAR PARK FOOTBRIDGE SOLUTION 50 Year Life extension design Targeted Galvanic anodes utilizing Hybrid CP • Pile Caps, lower arches & cross beams Coatings to atmospheric structure to prevent chloride ingress Hybrid CP anodes to tidal splash elements 11 LATE–STAGE INTERVENTION MORELL BRIDGE – OVERVIEW Arch bridge over the Yarra River in Melbourne • Constructed 1896 (Heritage listed) • First reinforced concrete bridge in Victoria • Built by Sir John Monash’s company (Monash & Anderson) • 99 metres long (3 x 33m spans) • 0.5m thick arches • Earth fill bridge (sandy clay) 12 MORELL BRIDGE Condition in 1994 • Spalling to ~10% of soffits • Carbonation past lowest matt of steel • Significant chloride levels • Active corrosion to 100% lower rebar 13 MORELL BRIDGE SOLUTION (1995) • CP through soil anode passes current through soil to lower rebar • Surface based concrete repair • 12 No. impressed current soil anodes • Surface protective coatings • Manual control system • Institute of Engineers Award Soil anodes Soil anodes installed through footpath 14 MORELL BRIDGE SOLUTION • Original repair in 1995 • Damage to cabling in 2017 during landscaping works • Damage repaired and anodes upgraded in 2017 for 30 year + life 15 CURRENT BRIDGE INSPECTION PRACTICES Level 1 and 2 Inspections • Visual only and only identify visible deterioration which impacts on the serviceability of the bridge Level 3 Inspections • Have the capacity to include the type of assessment needed, but are typically only triggered when a Level 1 or 2 Inspection identifies a need. Preliminary bridge inspections are typically undertaken by personnel with experience in bridge structural requirements, but rarely by those with materials durability experience 16 PROPOSED BEST PRACTICE APPROACH Early Stage Preliminary Durability Assessments • Validate design assumptions and allow identification of unexpected deterioration • Preliminary screening of deterioration mechanisms to enable predictive modelling • This design validation can be performed ~10 years after construction (or later) • Base future technical investigation schedule on initial modelling. Preventative Maintenance Approach • Plan to undertake preventative maintenance to greatly reduce the life cycle costs (eg application of coatings) 17 COMPARISON OF REMEDIAL OPTIONS Technique Overview When to Use Relative Cost Coatings Preventative Maintenance.

  • Victorian Heritage Database Place Details - 27/9/2021 Spencer Street Bridge
    Victorian Heritage Database place details - 27/9/2021 Spencer Street Bridge Location: Between Spencer Street & Clarendon Street,, MELBOURNE VIC 3000 - Property No B6799 Heritage Inventory (HI) Number: Listing Authority: HI Extent of Registration: Statement of Significance: The Spencer Street Bridge built by the Victorian Railways Construction Branch in 1929-30 is significant as a major new crossing of the Yarra River reflecting engineering and design standards intended to enhance the Yarra River as an aesthetic and recreational adjunct to the City of Melbourne. The Spencer Street Bridge is significant for aesthetic/architectural, historic, and technical reasons at a State level. Spencer Street Bridge was constructed after a long period of stagnation in road and bridge development in Victoria in a climate of controversy and rivalry between public authorities, local councils and politicians. The Spencer Street Bridge is of historical significance as the first major new crossing (as opposed to replacement of older bridges on existing crossings such as the 1924 Church Street Bridge) to be created over the lower Yarra in Melbourne after a considerable lull in such projects since the Morell Bridge of 1899-1900. Its construction demonstrates the political difficulties of the time and the growing importance of motor vehicle traffic to Melbourne's commerce. The Spencer Street Bridge was the first permanent structure over the Yarra built below "the falls" (a natural rock barrier that formed the upstream limit of practical river navigation) and as such is historically important because it was the first bridge to effectively cut the city off from direct contact with its port.

The Kearney map of 1855 shows land north of City Road (then Sandridge Road) as poorly-drained and avoided on account of its flood-prone nature. To the immediate south was Emerald Hill. The Port Melbourne railway crossed the river at The Falls and ran north of City Road. By the time of Commander Cox’s 1866 map, some industrial premises were located on the Yarra River bank and walking tracks connected them with the Sandridge Road and Emerald Hill.

  • Morell Bridge Formerly Known As Anderson Street Bridge Was the First Large Structure Built in Victoria Using Reinforced Concrete
    Engineers Australia Engineering Heritage Victoria Nomination Engineering Heritage Australia, Heritage Recognition Program For Morell (Anderson Street) Bridge, Melbourne, Victoria Earliest example of the Monier Concrete Arch Construction Method used in Victoria. March 2015 1 Front Cover Photograph Caption The Morell Bridge formerly known as Anderson Street Bridge was the first large structure built in Victoria using reinforced concrete. The bridge was built over a newer section of the Yarra River originally on dry land, and after construction in 1899 the river was diverted to flow underneath. The Bridge has three equal spans of Monier arch while encompassing cast iron balustrades and ornamental Victorian lights.
