Steel Detailing Services for Australian Fabricators
Tekla models, shop drawings and rebar documentation for Australian resources, energy and industrial steelwork. Our morning overlaps your afternoon, and drawings issued at our close are waiting by your next morning.
Detailing Capacity for Australian Steelwork
PetroHill provides Tekla detailing capacity to Australian steel fabricators, detailing firms and EPC contractors on resources, energy and industrial projects. Lahore is three hours behind Perth and five to six hours behind the east coast, so our morning overlaps your afternoon for calls and queries, and drawings issued at the end of our day are with you before you start the next morning.
Australian steelwork is detailed to the designer's AS 4100 design and fabricated to AS/NZS 5131, where the designer assigns a construction category (CC1 to CC4) that sets the fabrication, welding and inspection requirements. Our drawings carry what the shop needs for that category, with the coatings, marking and bolting specified in the contract documents. Concrete placing drawings follow the AS 3600 design and the project's scheduling convention.
Our senior team brings more than thirty years of heavy industrial and energy steel experience, gained mainly on oil and gas projects in the Middle East and Central Asia rather than in Australia. For Australian work we confirm your drawing standards, marking, connection conventions and shop preferences in a scope review before modelling, and we offer a fixed-price pilot so you can judge our drawings on your own job.
Process and resources structures suit our background best: conveyor support steel and transfer structures, pipe racks, platforms and access steel, equipment supports, and modification steel for operating plants, where member counts are high and fabricators need consistent drawings and accurate material lists.

Standards & Specifications
The construction category and design basis come from the designer; we detail to them and do not select the category or certify compliance. Fabrication and erection compliance under AS/NZS 5131 is the fabricator's and erector's. Working to a standard is not a claim of certification.
The scope of work records the applicable standards and editions for each package. A reference to a standard does not imply design verification or certification.

Common Questions
Related services
Can you detail to AS/NZS 5131 construction categories?
Yes. The designer assigns the construction category, CC1 to CC4, and we make sure the drawings carry the welding, bolting, preparation and inspection information it requires. Selecting the category and certifying compliance are not part of detailing.
Have you worked on Australian projects?
Our senior team's experience comes mainly from oil and gas projects in the Middle East and Central Asia, not Australia. Every Australian package therefore starts with a scope review of your standards and conventions, and our fixed-price pilot lets you check our drawings on your own job first.
How does the time difference work for Australian teams?
Our morning overlaps your afternoon, which is when calls and queries happen. Work then continues through the rest of our day, and agreed drawings are issued at our close, which is before the start of your next working day on the east coast and in Perth.
How quickly will we receive a quote?
We reply to quote requests within 24 hours (GCC working day). Send drawings or a scope summary with the deliverables, standards and target dates you have; where inputs are incomplete we list the assumptions we priced and the questions to close.
Can we start with a small trial package?
Yes. Our pilot is one assembly or a 5–10 t package, at a fixed price, delivered in 5 working days from receipt of complete inputs. It lets you check our model, drawing standard and checking on your own project before committing a larger package. NDA on request.
Send Your Drawings
We reply within 24 hours (GCC working day). A scope summary is enough to start; NDA on request.
