Dilapidation Reports
Construction, demolition, excavation or other nearby works can make it difficult to determine whether cracks or property damage existed before the project began.
Ostanes Engineering provides dilapidation reports that create a clear, dated record of visible and accessible property conditions before work starts, supported by photographs and documented observations.
Establish the Property Condition Before Work Begins
A dilapidation report captures a comprehensive baseline record of adjacent buildings, pavements, and council infrastructure before heavy construction starts. This objective record protects developers, builders, and asset owners against disputed damage claims.
External Walls & Facades
High-resolution photographic documentation of existing brickwork cracks, render defects, expansion joints, and cladding condition.
Internal Walls & Ceilings
Systematic room-by-room condition record of internal plasterboard cracking, cornice separation, and existing finish defects.
Driveways & Pavements
Documenting concrete driveways, footpaths, crossovers, and kerbs before heavy machinery and site access begin.
Retaining Walls & Boundaries
Assessing pre-existing leaning, displacement, cracking, and structural condition of boundary retaining walls and fences.
Outbuildings & External Assets
Recording sheds, garages, swimming pools, boundary walls, and patio slabs adjacent to proposed construction activity.
Council & Civil Assets
Documenting public roads, stormwater pits, nature strips, and utility easements where required by development approval conditions.
When Should You Arrange a Dilapidation Report?
Before Deep Excavation Works
Basement excavations, bulk earthworks, and batter cutting near property boundaries that could affect neighbouring ground support.
Before Demolition Activities
Heavy mechanical demolition, concrete breaking, and structural dismantling generating ground vibration and air shock.
Before Piling & Ground Compaction
Driven piles, sheet piling, bored piers, and dynamic roller compaction that transmit vibration to sensitive neighbouring structures.
Construction on Tight Boundaries
Building zero-lot-line walls, second-storey additions, or townhouses immediately adjoining neighbouring residential dwellings.
Development Approval Conditions
Council DA requirements, infrastructure agreements, or light rail corridor conditions mandating RPEQ pre- and post-works surveys.
Adjoining Owners Due Diligence
Property owners seeking independent baseline documentation before a major commercial or residential development starts next door.
Our Dilapidation Report Process
1. Scope & Property Access
We review construction plans, identify affected neighbouring structures, and coordinate access for systematic condition logging.
2. Baseline Site Survey
An engineering inspector captures high-resolution indexed photographs, crack measurements, and detailed descriptive notes.
3. Report Delivery & Post-Works
Receive a structured, timestamped Dilapidation Report. Post-construction comparison surveys available upon project completion.

Dilapidation Report FAQs
A dilapidation report is a formal, dated engineering condition survey documenting the exact structural and cosmetic condition of a building, driveway, or asset before nearby construction, demolition, or excavation starts.
It is often mandatory under Council Development Approvals (DA), infrastructure protection conditions, or Construction Management Plans for works near boundaries or public assets.
Developers and builders arrange reports to protect against unjustified damage claims. Adjoining property owners also arrange independent reports to protect their property rights.
The inspection must occur before any heavy machinery, demolition, piling, or excavation begins on site.
It includes hundreds of indexed high-resolution photographs, written defect descriptions, crack measurements, and location plans of all accessible areas.
It provides the objective before-and-after baseline evidence needed to verify whether cracks or defects existed prior to construction or occurred during works.
Yes. Upon project completion, we can re-inspect the property and produce a Post-Construction Dilapidation Comparison Report highlighting any observable changes.
All accessible internal rooms, external walls, roofs, driveways, boundary fences, retaining walls, and civil infrastructure agreed in the survey scope.
