Start with the real engineering question.
These pages are written for the moment before an engineer chooses a standard, clause, repair method or inspection path. Each question page gives a practical answer, warning signs, a step-by-step review pathway and detailed case studies.
Is this a repair or a plant modification?
A detailed decision pathway for sorting true restoration work from changes that alter load path, duty, controls, safety function or compliance basis.
Open question →02Can a cracked component be weld repaired?
How to assess crack mechanism, material, duty and inspection before deciding whether repair, redesign or replacement is appropriate.
Open question →03Does my air receiver need registration?
A practical screening guide for pressure-equipment identity, hazard level, documentation gaps and registration-related questions.
Open question →04AS 3990 or AS 4100: where should I start?
How to decide whether the steelwork should be approached as mechanical equipment steelwork, structural steelwork or a defined hybrid interface.
Open question →05Which NDT method should I discuss with an inspector?
A plain-language guide to matching inspection purpose, defect type, material and access to the right NDT conversation.
Open question →06When should the OEM be involved?
A framework for deciding when original-equipment-manufacturer input is useful, necessary or critical to the engineering basis.
Open question →07Does high indoor CO₂ prove the ventilation is non-compliant?
How to use CO₂ as ventilation evidence without turning one sensor reading into a false compliance test.
Open question →08Can natural ventilation replace mechanical ventilation?
A practical pathway for deciding whether permanent openings provide a valid natural-ventilation strategy.
Open question →09Does this HVAC change affect fire and smoke control?
Screen fan, AHU, damper, duct and control changes for hidden fire-mode and smoke-control impacts.
Open question →10Is our HVAC maintenance program enough for microbial control?
Move beyond contractor attendance to asset-based maintenance, defect close-out and useful records.
