Post-tensioned slab engineering for a major multi-storey development in Cremorne. The work included detailed PT floor-system analysis, tendon profiling, prestress optimisation, flexural and serviceability checks, punching shear assessment and local reinforcement design. Coordination of large penetrations, slab set-downs, transfer zones and construction-stage requirements formed an important part of the design development.

Particular attention was given to irregular geometry, architectural interfaces, concentrated loads and local discontinuities to verify the adequacy of the proposed floor system.

Structural EngineeringCarlton, VIC

La Storia, Carlton

Independent third-party engineering review of the post-tensioned and reinforced-concrete slab design for the La Storia development. ASC reviewed the design actions, slab thicknesses, tendon layouts, prestress levels, flexural capacity, punching shear, deflection and reinforcement detailing. Critical structural interfaces and discontinuities were independently checked to verify the design and identify any areas requiring further consideration by the project structural designer.

Structural EngineeringHampton, VIC

58 Beach Road, Hampton

ASC provided independent third-party review of the post-tensioned slab design prepared for the multi-storey development at 58 Beach Road, Hampton. The review included verification of slab actions, tendon distribution, prestress levels, flexural capacity, punching shear, deflection and reinforcement requirements. Detailed consideration was given to penetrations, slab edges, support conditions and architectural interfaces to independently confirm the structural adequacy of the proposed slab system.

Bridge Engineering & Asset ManagementGannawarra Shire, VIC

Gannawarra Shire – Level 3 Bridge Inspection & Load Rating Program

ASC delivered Level 3 structural inspections, condition assessments and load ratings for 15 regional road bridges. The work included detailed defect mapping, review of available drawings, verification of structural dimensions, material and reinforcement investigations where required, analytical modelling and assessment of bridge capacity under relevant road-traffic loading. Findings were converted into practical recommendations covering load management, maintenance, rehabilitation and strengthening.

Bridge Engineering & Asset ManagementLower Loddon, VIC

Lower Loddon Road – Pyramid Creek Bridge

Detailed Level 3 assessment and structural load rating of the multi-span reinforced-concrete bridge over Pyramid Creek. ASC assessed the deck, girders, piers, bearings, abutments and other critical structural components, with observed defects incorporated into the structural capacity assessment. Analytical checks were undertaken to establish current load-carrying capacity and to identify appropriate rehabilitation and strengthening measures for continued heavy-vehicle operation.

Bridge Engineering & Asset ManagementTragowel, VIC

Tragowel Road – Two Mile Creek Bridge

ASC completed a Level 3 structural inspection and load rating of the two-span precast inverted U-slab bridge over Two Mile Creek. The investigation combined detailed site inspection, dimensional verification and reinforcement identification with structural modelling and capacity assessment. The bridge was assessed for critical flexural and shear actions, with deterioration and existing condition incorporated into recommendations for maintenance, rehabilitation and future load management.

Bridge Engineering & Asset ManagementBuangor, VIC

Buangor–Ben Nevis Road Bridges

ASC delivered Level 3 inspections, structural assessments and load ratings for multiple regional bridges along Buangor–Ben Nevis Road. The work included detailed assessment of deck systems, beams, substructure elements, bearings and foundations, together with structural modelling to establish current capacity. Strengthening solutions were developed where required, with emphasis on constructability, durability and maintaining bridge operation during future works.

West Gate Bridge Strengthening & Rehabilitation

Bridge Engineering & Asset ManagementMelbourne, VIC

West Gate Bridge Strengthening & Rehabilitation

Senior members of the ASC team have extensive experience in the structural assessment, strengthening and rehabilitation of Melbourne's West Gate Bridge. Engineering work has included external post-tensioning, CFRP strengthening, fatigue-sensitive steelwork, structural brackets, bearings, expansion joints and construction-stage assessment. Complex load paths, staged installation, existing-structure behaviour and maintaining bridge operation were key considerations throughout the strengthening works.

Senior team experience in the structural strengthening and rehabilitation of four major road bridges across rail and waterway interfaces. Engineering solutions included CFRP strengthening, steel plating, reinforced-concrete overlays, barrier upgrades and expansion-joint works. Detailed structural analysis was used to assess existing capacity, determine strengthening demand and develop practical solutions that could be installed within constrained construction and operational environments.

San Remo Bridge Rehabilitation

Senior team experience in the structural assessment and strengthening design of the San Remo Bridge. The engineering included detailed assessment of the existing prestressed-concrete structure and development of external post-tensioning solutions to improve structural capacity and extend service life. The design required careful consideration of existing prestressing, anchorage zones, tendon routing, load transfer, durability and construction sequencing within a marine environment.

West Gate Bridge – Temporary Works & Construction Engineering

Temporary works and construction engineering supporting major bridge strengthening and rehabilitation works. The scope included temporary access systems, support arrangements, construction-stage structural checks, local load assessments and staged load-transfer requirements. Temporary conditions were assessed independently from the final structural condition to ensure each stage of construction remained stable and within acceptable structural limits.

Gorgon LNG – LNG Tank Temporary Works

Selected senior team experience in temporary works and post-tensioning engineering for major LNG storage tanks. The work included stressing platforms, temporary access systems, anchorage arrangements, support framing and construction-stage engineering associated with large-scale post-tensioning operations. Temporary systems were designed for significant construction loads while maintaining safe access and compatibility with the permanent tank structure.
