Faulty construction - problem-solving advice

Building consultants at Building Diagnosis Centre provide forensic services and advice on faulty construction works and faulty remedial work of residential buildings, strata buildings include residential units and commercial premises.

  • The common problems our building engineering consultants and building waterproofing experts discover the majority of the time, is caused from faulty and damaged waterproofing membranes and flashings.
  • Building inspections find unsuitable waterproof membranes are causes of water leaks including movement cracking to brick walls and concrete from differential building movements, omission of expansion and control joints, and faulty construction practice.
  • These are considered structural faults and eventually if undetected which often is the case, cause water ingress and in coastal properties, allow soluble salt chloride to enter the materials and accelerate corrosion causing very expensive rectifications.
  • Building consultants' inspections develop our problem-solving advice to our clients that faulty construction could have easily been overcome with proper specifications and or the specifications being followed as recommended by the manufacturers and proper programmed supervision during the construction process.

Visual inspections of buildings and structures

Building Diagnosis Centre advise that visual inspections of buildings and structures in the majority of cases, is the normal first stage procedure of investigations. This first approach is the least expensive and will not cause damage to building and finishes.

  • An experienced building and design engineering consultant with extensive knowledge of both the design and construction processes, can confidently advise on building issues during visual building inspections regarding the conditions of buildings and structures as experts in these fields. However it is often forensic investigations will follow.
  • Our advice will include reasons of damage and causes. Usually a combination of concerns that need to be pursued by in-depth forensic investigations including destructive intrusive observations.
  • Investigations may lead to a study of the building contract and plans and specifications, including physical destructive exploratory work where invasion into the building fabric occurs.
  • It is only once walls, floors or roofs are physical invaded, the exact cause can be diagnosed and a solution recommended in a scope of works / specification for the necessary rectifications.
  • Once these physical intrusive investigations commence building consultants' costs escalate as it's time-consuming work.

  • Depending on our program engagement with our clients, we recommend our building consultants and building design experts' progress inspections occur at "critical stages" of the works. It is often the case we have to reinspect due to finding faulty work.
  • Our building inspection reports provide a list of the critical stages requiring inspections of work in progress. Building inspections must occur prior to the licensed builder continuing to the next stage.
  • The periodic and progress inspections in complicated and waterproofing membrane installations, could be as often as  daily for a duration of one or more hours depending on the situation at the time of the work being performed.
  • Progress inspections assesses the quality of the construction work being performed by a licensed builder and to ensure the work at that time complies with the building contract, plans and specifications, manufacturers details and statutory requirements. The building inspection report lists any building faults or issues.

Physical intrusion investigations and inspections

  • The actual physical destruction work is provided by an approved remedial building contractor experienced in this field that we recommend to our clients when we consult.
  • Once the materials are removed it allows our building and design, engineering consultants and experts to inspect and study the previously concealed materials and conditions to pinpoint the cause of the particular problem or issue and to make sure safe and proper recommendations in the form of a works specification for repair or rectification.
  • Building Diagnosis Centre provides specifications and reports and prior to these documents being completed it is more often than not that this physical destructive investigation work needs to be provided, including for expert evidence in court cases.
  • It is also necessary and not only to correctly diagnose procedures to rectify but presenting sufficient information to acquire tenders from experienced licensed remedial building contractors, as it limits post-contract cost variations occurring.

Corrosive concrete core samples and with magnesite - NATA tests (National Association Testing Authorities Australia Laboratory)

Building Diagnosis Centre expertise is investigating spalling concrete corrosion and explosion damage, particularly for strata internal magnesite covered concrete floor slabs,  balconies of strata unit buildings, local government buildings and grandstands, multilevel carparks in shopping centre and suspended concrete swimming pools.

  • The majority of our investigations of spalling concrete corrosion damage are found in buildings and structures situated along the Sydney (NSW) coastline. Issues when close to surfing beaches, the breaking waves and easterly driven winds, impregnates properties with soluble salt laden air. Concrete and brick corrosion goes undetected internally and severely increases in properties closest to the beach line.
  • Buildings and structures that have been properly designed and constructed to compact the corrosive effects of the coastal environments and are well-maintained at frequent intervals, will resist the soluble salt (chloride) 'eating' through the external concrete facade, waterproofing membranes and structural steel components. It’s when brown spots appear; rust stain marks, and cracks in the surfaces, is when we advise not to ignore the evidence of corrosion already within the concrete.
  • Part of our forensic investigations as building consultants and building engineering experts, is taking core hole samples from the concrete and test at registered NATA Mahaffey laboratory for chloride ions and carbonation content including to assess corrosion of the embedded steel reinforcement to determine our suitable specification for rectification by specialist remedial building contractors.

Project Manager Client Representation

  • Although we assist the licensed experienced building contractor and remedial building contractors to avoid delays in the work or stop faulty workmanship practices, or any omissions in their works, our aim is to ensure our clients will have a sound building on completion in representing them as their expert.
  • A by-product of us being the client's representative, provides building contractors with a free level of direction and quality control that eliminates any disputes occurring either during the works or on completion or down the track within warranty.
  • Part of being the client's project manager representative, is for the client including the building contractor to notify our consultants at predetermined stages prior to proceeding further with their works, to give our consultant sufficient time to provide the inspection and to certify that stage for our client.
  • The more complex the work the more inspections particularly waterproofing membranes as there are many stages of events during the course of waterproofing. Similarly, during the rectification of spalling concrete or rust corrosion steel damage, we need to inspect each of a 6- stage rectification. If we are not satisfied with a stage, we request the contractor rectifies that stage and advise when ready for our re-inspection.
