Engineering Services at a Glance
Seven engineering practices.
One delivery discipline.
Every engagement is scoped as engineering support against a client-approved design basis — your specifications, your drawing standards, your review and approval gates.
Plant 3D & Digital Engineering
Discipline models built or extended to project standards and reviewed for constructability.
As-Built Engineering
Bringing drawings and models back into line with what is actually installed in the field.
P&ID & Engineering Data Support
Keeping engineering documents, revisions and models consistent as a project changes.
Reality Capture & Digital Conversion
Turning existing physical assets into measurable, model-ready engineering information.
Structural & CAD Engineering
Fabrication-ready detailing and drafting production for structures and general engineering.
Engineering Analysis
Simulation and model-based review that test design intent before anything is built or modified.
Engineering Lifecycle
From engineering inputs
to a verified digital asset.
Symbiosys can be engaged at any point on this chain — a single deliverable, one phase, or continuous support across the lifecycle of an operating asset.

Detail Engineering
Detail
Engineering.
We work from your engineering inputs and produce the modeling, checking and documentation that detailed engineering demands — as an engineering support partner operating inside your project structure and against your client-approved design basis.
Engineering authority, approvals and design responsibility remain with your licensed engineering organisation unless the engagement is explicitly defined otherwise.

Plant 3D & Digital Engineering
A model that holds
the whole plant together.
The 3D model is where disciplines meet. We build new models, extend existing ones, and keep them accurate enough to be the reference every drawing and material take-off is generated from.
Model creation
Equipment, piping, valves and fittings, supports, platforms, structures and instrumentation modeled to project standards and levels of detail.
Model from reality
Registered point cloud data converted into a coordinated 3D model of existing plant — the practical route where drawings no longer match the field.
Model review & checking
Clash and interference checking, accessibility and maintenance envelopes, and review-model preparation for 30/60/90 percent model reviews.
Model-driven deliverables
Layouts, isometrics, support drawings and material take-offs extracted from the model so documentation and model stay in step.
P&ID Administration
Engineering
information that
stays current.
Projects change continuously — line revisions, equipment changes, field modifications, comment cycles. We provide the sustained drafting and documentation effort that keeps P&IDs, drawings and revisions consistent with the current design.
Set up ongoing supportP&ID administration
- P&ID updates
- PFD updates
- Existing P&ID modifications
- Symbol and library support
- Drawing setup and templates
- Revision updates

Engineering data quality

Site Surveys & Redline Updates
The bridge between
the plant and the drawing.
Field verification is where as-built accuracy is won or lost. Our survey and redline workflow records what is physically installed and carries it through to updated engineering documentation.
- 01
Existing Documents
Collect and review the current drawing and model set.
- 02
Site Survey
Walkthrough, circuit identification, photographs and measurements.
- 03
Field Verification
Sizes, specifications, fittings, elevations and connections verified.
- 04
Redlines
Mark-ups prepared against the existing drawings.
- 05
Engineering Updates
Drawings, P&IDs, isometrics and models updated from the redlines.
- 06
Verification
Internal checking and client or site confirmation.
- 07
Final As-Built
Issued as-built package with revision history.
Field scope
- Site walkthroughs
- Existing document review
- Piping circuit identification
- Physical measurements
- Pipe size and specification verification
Recorded detail
- Valve, fitting and flange verification
- Elevation and coordinate recording
- Equipment connection verification
- Existing support identification
- Field modification recording
Engineering output
- Redline drawing preparation
- Existing drawing updates
- P&ID updates
- As-built isometrics
- Final site and client verification
As-Built Engineering
Bring the records back
in line with the plant.
After years of modifications, tie-ins and turnarounds, engineering records rarely match the installed condition. We reconstruct that alignment — document by document, line by line — so the next modification starts from something you can trust.
- Field Reality
- Survey
- Redline
- P&ID
- Isometric
- 3D Model
- Verified As-Built Package
As-Built P&IDs
Existing P&IDs updated to reflect verified field conditions, with revision clouds and change history maintained to your standard.
As-Built Isometrics
Isometrics prepared or corrected from field data — dimensions, materials, supports and bill of material aligned with what is installed.
Updated Layouts & Models
Layout drawings and 3D models updated where the engagement requires a maintained digital record of the asset.
Supporting Documentation
MTO/BOM where applicable, survey records, mark-up sets and a documented trail from field observation to issued as-built.
Laser scanning is one available approach to as-built capture, applied where the asset, access and accuracy requirement justify it — many as-built scopes are delivered through conventional field survey and verification.
Scan to Digital Engineering
Reverse engineer reality.
Forward engineer the future.
The capability Symbiosys has built its engineering practice on: converting existing physical assets into accurate, usable engineering information.
