Blog/08 notes
Notes from the field.
Plain explanations of the engineering questions that come up on mining, oil and gas and construction jobs in Queensland, written for the people who have to commission the work.
Form 15 and Form 16 in Queensland: who signs what, and when
How Queensland's Form 15 design certificate and Form 16 inspection certificate work for engineered aspects of building work such as platforms, equipment supports and mezzanines, who counts as a competent person, and the sequence that avoids holdups at final inspection.
Read the post →Platforms, walkways and ladders: the AS 1657 non-compliances we see most
The recurring ways fixed platforms, walkways, stairs and ladders on Queensland industrial sites fall short of AS 1657, what the standard expects instead, and which fixes are cheap.
Read the post →What an RPEQ is, and when Queensland law says you need one
RPEQ registration under the Professional Engineers Act 2002 (Qld): what counts as a professional engineering service, how it differs from CPEng, and how to check an engineer before you hire.
Read the post →As-built drawings: what they are, why they need an RPEQ signature, and how to get them back fast
What separates an as-built drawing from a marked-up IFC, why the sign-off is an engineering decision rather than a formality, and the pack to send for a quick turnaround.
Read the post →WRAC explained: the risk assessment behind most Queensland mine-site changes
How a Workplace Risk Assessment and Control (WRAC) session works, when it is required on Queensland mine sites, and how to get engineering value out of it rather than paperwork.
Read the post →Why one engineer across structural, mechanical and piping saves rework
On small and brownfield industrial projects the structural–mechanical–piping interfaces are where problems hide. A single engineer who owns the whole load path catches them before fabrication.
Read the post →FEA in practice: when analysis earns its keep, and what to hand the engineer
Finite element analysis is the right tool for non-standard geometry, weight optimisation and fatigue, and the wrong tool for a standard beam. When to use it, what inputs it needs and what a good FEA report contains.
Read the post →Pipeline pressure testing: what a hydrotest actually checks, and what makes one fail
How field pressure testing works for gas and liquid petroleum pipelines (AS 2885.5), buried flexible pipelines (AS/NZS 2566.2) and plant piping (AS 4041): the sequence, the records, and the usual reasons a test is rejected.
