Engineering Detailing & Outsourcing FAQs
Straight answers to the questions EPC contractors, engineering consultancies and fabricators ask before commissioning a drawing, model or detailing package.
Services & Scope
What engineering services does PetroHill provide?
We provide civil and structural CAD drafting, 3D structural and plant modelling, structural steel detailing and fabrication documentation, RCC and reinforcement detailing, brownfield drawing updates, material take-offs and engineering documentation. Each package is defined against the available design inputs and required outputs.
Can we outsource a Tekla or structural steel detailing package?
Yes. A defined package may include a structural modelling scope, shop, assembly and single-part drawings, erection documentation and agreed material reports. We first confirm design inputs, approved connection details, software versions, drawing standards, responsibilities and review milestones.
Can you prepare RCC reinforcement drawings and BBS?
Yes, within an agreed scope based on supplied structural and reinforcement design information. Deliverables can include foundation and RCC details, rebar placing information and bar bending schedules.
Do you undertake brownfield modifications and as-built drawings?
We can support updates to existing structural drawings and models using verified existing records, site surveys or client-provided markups and approved modification information. The accuracy and availability of source records are confirmed during scope review.
Can you support onshore and offshore industrial structures?
Relevant senior professional experience includes both onshore and offshore project environments. Potential packages include pipe racks, access platforms, equipment supports, industrial steel frames and related structural documentation, depending on agreed resources and design inputs.
Which sectors and regions do you serve?
Our services are relevant to oil and gas, gas processing, refining, petrochemicals, offshore facilities, power and industrial infrastructure. We are based in Lahore, Pakistan and work with engineering organisations in the GCC and internationally.
Quotations & Working Together
What information should we send for a quotation?
Share a scope of work or deliverable list, available approved drawings or models, structural specifications, project location, desired output formats, the approximate drawing or tonnage scope where known, and target dates. Where inputs are incomplete, tell us what is available so we can identify assumptions and questions. We reply to quote requests within 24 hours (GCC working day).
Can you work remotely with overseas EPC project teams?
Our engagement model is remote technical production, with defined communication, queries, model and drawing exchanges and client review interfaces. Meeting times, access controls and milestone schedules are confirmed for each project.
How do you handle confidential drawings and project information?
Confidentiality requirements, non-disclosure terms, authorised access, permitted uses and file exchange methods should be agreed before sensitive project files are shared. Send an NDA for review if your project requires one.
Responsibility, Standards & Quality
Do you undertake connection design or certify structural calculations?
We produce models, drawings and detailing from the engineering information supplied by your design team. Connection design, structural calculations, certification and approvals stay with your engineer of record unless a separate scope is agreed.
Can you work to Saudi Aramco, ADNOC or other project-specific standards?
We can review the codes, standards, document conventions and project specifications you supply and confirm which requirements can be supported for the proposed package. Specific code editions, responsibilities and checking and approval arrangements are agreed before work begins. This does not imply approval or vendor status with any project owner.
How are reviews, revisions and quality checks managed?
The project-specific delivery plan defines document numbering, input versions, production checks, client review stages, comment resolution and issue status. Any independent checking or specialist verification must be agreed explicitly and is not presumed on every assignment.
What software and file formats do you use?
The senior team has experience in Tekla Structures, AutoCAD and other modelling and drawing environments relevant to industrial projects. Current supported software, licence availability, version compatibility, native files, PDFs and exchange formats are confirmed for each engagement.
Service-specific questions are answered on each service page, alongside its scope, inputs and deliverables.
