An Overview Of Our Building Investigation Procedures –

  • Building diagnostics is the process of determining the causes and solutions to building damage, problems and disputes. Building Diagnosis Centre forensic building consultants and waterproofing experts provide this service. Our firm is guided by our chief expert consultant Robert Speirs-Ferrari who has achieved a status of fellow, chartered, accredited, licensed and insured. Robert has a reputation as one of Sydney’s best building consultants and waterproofing consultants on the northern beaches and the eastern coastal suburbs of Sydney, and further afield including Australian capital cities. 
  • We advise that building and waterproofing over the life of a building structure will suffer damage caused by normal wear and tear, will eventually deteriorate and requires serious work at the 50 year period. We readily determine the causes and solutions for this type of 50-year damage to residential, strata, commercial, industrial, local government and most other property. We advise early damage is another type, and more severe as it occurs from latent defects concealed within building structures, usually discovered as a result of ingress of rainwater or building movement, alerting building owners to seek independent assessment reports. In this case, we provide independent building expert comprehensive reports for property owners to discuss with their building people.
  • What causes latent concealed building defects? They are always created by the building people that may at times be inexperienced without the necessary skill to problem solve and identify inappropriate materials, processes and practices, and without the support of independent inspections and certification. We further advise that latent defects, amounts other causes, occur when bypassing the statutory requirements of the National Construction Code Building Code of Australia, and Australian Standards. We advise the majority of time building defects end in costly rectification and disputes in NSW Fair Trading meditations and NCAT Tribunals and Courts. Mistakes could have been initially avoided by having experienced independent building consultants and waterproofing consultants inspect the work in progress during critical stages. 
  • Our building and waterproofing diagnostic consultants are experienced and thorough for critical stage inspections and to prepare specification remedial works including project manage builders’ jobs. Alternatively, our diagnostic building waterproofing experts after assessing a property will develop a suitable report for litigation per the Expert Witness Code of Conduct. No matter what the building and construction issues are, our forensic experts will advise to inspect, test, report, prepare specifications, call for tenders and project manage remedial work making your building permanently waterproof and safe. We don’t advise a “quick cut-corner fix”.

What Are The Benefits To Our Clients –

  • Our building consultants do the worrying for clients when taking on their building and construction issues – is what we do best. We will explain in layman’s language the technical building construction faults and deterioration that we investigate either through visual inspection or destructive physical intrusion into the building fabric. We will advise you and keep you informed throughout the whole process. Our experts will continue the service until there is certainty as to the extent of damage and the causes which at times requires taking core samples out of concrete and masonry brick walls for testing in a registered NATA laboratory.
  • We include the best method to have the damage or issue rectified, drafted in a recognised professional report used for either rectification purposes or litigation and tribunal purposes. Our building consultants will estimate costs, call tenders from our accumulated list of recognised, experienced remedial building contractors, evaluate the costs and undertake the project management services until certified satisfactory completed.

Our Guarantee –

  • The services that our building consultants deliver stops people’s homes and businesses from long-term water penetration in some cases for many years due to previous unsatisfactory attempts to have it rectified. We assess concrete structures for damage, followed by designing remedial work activities that we certify during our critical stage inspections. This ensures the work is satisfactorily completed and progress payments are made on that assurance.
  • Our expert opinion advice and reports result in a suitable outcome when negotiating and entering into mediation and tribunals and court cases. Our strategies and professional building consultancy and construction activities over the last 40-years have proven very successful and satisfied clients. As a reference, refer to our current and recent clients listed under the heading Projects.

We Prepare Our Fee Cost Agreement to Provide –

  • Our building engineering professional consulting services include opinions and advice over the telephone, at the property or in court as an expert witness.

  • When applicable draft inspection reports, specifications and expert reports and assist clients in NCAT consumer tribunals, local and district courts.

We Specialise In New and Older Buildings and Structures –

  • With new buildings the majority of the time we resolve non-compliant disputed work regarding inadequate waterproofing and damaged structures from water penetration. These building disputes also occur in non-new buildings and structures during renovations and repairs.
  • Hence we assess general construction defects and deterioration mainly to stop or control structural severe damage and decay, i.e. water penetration causing spalling concrete explosion damage and structural steel rust expansion corrosion, suffering the effects of coastal soluble salt attack – please refer to our information page.

Our Clients’ Older Buildings and Structures –

  • Our investigations also include evaluation of the building structure after physical destructive exploratory works (we supervise remedial building contractors to carry out these works) into walls, floors and roofs and below ground level.
  • Whereby our building consultants and engineers in Sydney collect samples for testing of materials containing chloride and carbonation in concrete slab floors and corrosive magnesite topping, the fibro-cement material containing asbestos fibres, cracked and sagging concrete balconies including when evidence of rust stain marks exist around cracks and spalled areas, particularly coastal properties adjacent to surfing beaches.
