Independent Engineering Review for Adjoining Owners in Melbourne

Construction and excavation works near property boundaries can create significant structural risks for adjoining owners, particularly where retaining walls, deep fill, drainage infrastructure or existing footings are involved.

Engineering Vision provides independent structural and civil engineering assessments for adjoining owners involved in Protection Works matters and Building Appeals Board (BAB) disputes throughout Melbourne and Victoria.

Our role is to critically review the engineering and construction documentation associated with proposed developments and identify potential structural, excavation, drainage and retaining wall risks that may affect neighbouring properties.

Where proposed slabs, edge beams or foundations are constructed close to existing retaining walls, structural interaction may occur due to:

• settlement, 
• construction tolerances, 
• soil movement, 
• or differential loading. 

Independent review can help identify whether adequate separation, support and structural detailing have been properly considered.

Sites containing deep fill or highly reactive soils may present additional engineering challenges. In some circumstances, further geotechnical investigation or clarification may be required to properly assess:

• expected ground movement, 
• footing performance, 
• retaining wall stability, 
• and long-term settlement behavior. 

Drainage infrastructure located near boundaries can increase excavation depth and influence adjacent structures. Review of invert levels, drainage offsets and LPOD details is often necessary to properly assess construction impacts and flood risks.

Under the Building Act 1993 (Victoria), adjoining owners may receive Protection Works notices requiring a response within a limited timeframe.

These matters may involve:

• Form 7 Protection Works Notices 
• Form 8 Responses 
• disputes regarding excavation or structural risks 
• requests for additional engineering information 
• Building Appeals Board (BAB) proceedings 

Independent engineering review may assist adjoining owners in understanding:

• whether sufficient information has been provided, 
• whether additional investigation is required, 
• and whether the proposed works adequately address structural risks to neighbouring properties. 

Engineering Vision provides:

• Independent Protection Works assessments 
• Structural engineering review 
• Retaining wall assessment 
• Excavation risk review 
• Drainage and civil engineering review 
• Review of geotechnical reports 
• Technical submissions and engineering correspondence 
• Expert engineering opinions for adjoining owners
