ASME · API · EN · ISO · AutoCAD Plant 3D · AVEVA E3D · Ansys · Abaqus · Tekla · CAESAR II
Documentation & Handover
Calculation reports, drawings, inspection records and handover documentation are coordinated and delivered transparently.
How we work
From a single component to a production package, we manage material traceability, welding quality, dimensional control and protective treatment as integral parts of the fabrication flow.
At project start, the technical scope, interfaces, schedule and acceptance criteria are clarified together. Changes are documented throughout design or site execution, and critical decisions progress with client approval.
Project deliverables
- Technical assessment and scope note
- Calculations, drawings or inspection reports
- ITP / inspection points and tracking records
- Handover dossier, revision list and close-out summary
Information needed for a quote
Existing drawings, specifications, photographs, equipment data, site location, target date and any quality requirements make the first technical discussion faster and more effective.
Engineering approach
Silisium treats this service not as an isolated work item, but as a technical decision process connected to plant safety, availability and investment objectives. At the first discussion, we review the client expectation, condition of the existing equipment, available data set and delivery schedule together. This removes assumptions that may look reasonable in design but do not stand up in fabrication, on site or in operation. Cross-discipline interfaces, independent review needs and client approval points are identified early where required.
The reliability of the work is directly affected by the quality of the input data. We therefore review available drawings, data sheets, P&IDs, material certificates, maintenance history, site photographs and measurements in a controlled manner. Missing or conflicting information is collected in a clear data-request register. Design inputs are verified against real operating conditions including pressure, temperature, cycles, environmental effects, transport and lifting, erection tolerances and accessibility.
Planning and technical input management
The work plan identifies the deliverables and the decision supported by each of them. Calculations, drawings, site checks and tests are not performed in isolation; they are related to the project schedule and fabrication or procurement needs. For critical technical topics, we prepare concise decision notes explaining alternatives, assumptions, risks, impacts and the recommended path. This allows the project team to understand not only the result, but also how the result was reached.
During execution, defined inspection points secure quality within the workflow. Material identity, welding and erection preparation, dimensional compliance, NDT scope, test prerequisites and final acceptance are followed against the applicable codes and client specification. Where deviations occur, their effect is assessed technically, while corrective action, repair procedure or additional verification is recorded. The approach is designed not only to find errors, but also to prevent their recurrence.
Execution, quality and site coordination
Site and workshop coordination explicitly includes safety. Lifting, hot work, confined spaces, energy isolation, work at height and access are considered alongside technical planning. Work sequence, equipment access and temporary support needs are assessed in advance. In operating plants, we maintain regular communication with operations teams so permits, isolation limits and commissioning prerequisites remain clear.
A structured reporting rhythm makes the project position visible to every stakeholder. Progress, open technical topics, risk register, change list and quality status are updated together. The records can be adapted to meetings, daily site reports or formal handover files. This creates a common working basis for engineering, procurement, fabrication, erection and operations without losing critical information between disciplines.
Documentation, handover and next steps
At handover, simply filing documents is not enough. Calculation reports, approved drawings, material and welding records, test results, closed deviations, as-built information and maintenance notes are assembled under a logical index. This structure provides quick access during audits, commissioning, future modifications or failure investigations. Before handover, open items are reviewed and responsibilities are followed through a clear close-out list.
At quotation stage, the objective is not only to offer a price, but to define a dependable scope. Specifications, drawings, required codes, target date, site conditions, client responsibilities and interfaces are reviewed together. As uncertainty is removed, the schedule, resources, equipment and quality plan can be developed more realistically. Where useful, Silisium compares alternative execution scenarios in the first technical meeting and supports the decision process.
Controllable progress, open communication and technical traceability are essential on every project. Scope changes, decisions and inspection results are therefore shared with the responsible parties, and issues affecting the next phase are made visible without delay.
The client operating objective, maintenance window and acceptance expectation remain at the centre of the solution. Depending on the need, we combine desk engineering, workshop support, site coordination and independent technical review in one aligned work plan.
The methodology and document format are scaled to suit the project size, while the principles of safety, quality, record discipline and code compliance remain unchanged. A small revamp is therefore managed with the same technical care as a major investment package.
