Assessment of Bay Creek Bridge

Level 2 & Level 3 Inspection, Structural Assessment, Load Bearing Capacity, Strengthening Design, & Associated Cost Analysis Of Bay Creek Bridge

Project Scope

Level 3 Inspection, Structural Analysis, Strengthening Design, and Load Capacity Assessment (Rating Factor) of the Bridge.

Single-span Bay Creek Bridge is a composite Railway Line Steel-Concrete bridge consisting of one deck salb supported by two cast-in-situ concrete abutment with the the total length of 7.10 m and total width of 5.36 m and carriage path width of 4.60 m.

The structural components of the bridge are listed as follows:

  • Deck Slab: Composite railway line steel and cast-in-situ concrete
  • Two cast-in-situ concrete abutments (A1 & A2)
  • Three Concrete Piles for each Abutments (P1, P2, and P3)

The following tasks were carried out:

  • Detailed Inspection in Accordance with VicRoads “Road Structure Inspection Manual – 2018”
  • Measurement of all Structural Components (Site-Specific Measurements) as there was not any drawing available
  • Measurement of all Material Properties utilising NDT Techniques
  • Modelling and Structural Analysis of the Bridge Utilising SAP 2000 Computer Software in Accordance with AS 5100.7:2007 Bridge Assessment
  • Calculating Rating Factor of the Bridge

The following NDT Techniques were carried out:

  • Compressive Strength (SONREB Method (combining method) utilising Ultrasonic Pulse Velocity and Digital Rebound Hammer)
