Six Technical Services
From a defined drawing package to an outsourced detailing assignment. Working to your project requirements means confirming applicable standards, software versions, drawing conventions, discipline interfaces, checking responsibilities and revision procedures before the package proceeds.
Civil & Structural Engineering Drafting
Prepare and update structural general arrangements, framing plans, elevations, sections, foundation and equipment-base drawings from approved engineering inputs. Dimensions, reference levels, interfaces and revisions are coordinated within your drawing standards.
Learn more
3D Structural Modelling & Plant Model Support
Tekla steel models and suitable plant structural model updates developed from agreed design information in supported software environments, with coordination views, exchange files and documentation outputs where included in scope.
Learn more
Structural Steel Detailing & Fabrication Documentation
Engineer-approved structural information translated into steel detailing models, assembly and single-part shop drawings, specified connection details, erection plans and fabrication schedules for pipe racks, platforms and industrial steelwork.
Learn more
Reinforced Concrete & Rebar Detailing
Concrete structural details, foundation and equipment-base drawings, reinforcing-bar placing details and bar bending schedules (BBS), based on approved concrete design and project detailing requirements.

Why EPC Teams Engage Us
Engineering production is most useful when inputs, drawing responsibilities, review cycles and issue status are clear. We structure each assignment around the information your project already controls and the deliverables your downstream teams need.
- 01
Defined Inputs
Work from approved drawings, project specifications, model references and vendor information; raise information gaps before detailing.
- 02
Fabrication-Focused Outputs
Produce scoped general arrangements, 3D models, shop, assembly and single-part drawings, reinforcement schedules and quantities.
- 03
Controlled Revisions
Track drawing and model revisions, incorporate consolidated review comments and identify superseded information.
- 04
Project-Specific Delivery
Confirm software and version, drawing standards, checking responsibilities, exchange formats and issue milestones for each package.

Common Questions
What EPC contractors, consultancies and fabricators usually ask before commissioning a package.
All frequently asked questionsWhat 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.
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 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.
Need structural drawings, TEKLA modelsor fabrication details for your next project?
Share your scope, drawings and required deliverables. We can review the information available and clarify the proposed production package.
