Serving domestic & international clients

Engineering that begins at the connection, not the render

Sri Kandhan Engineering Solutions Private Limited is an engineering design and detailing solutions provider based in Tiruchirappalli, Tamil Nadu, India, founded on a single principle: the integrity of a structure is determined at its connections. Our process works backwards from the connection. Bolt groups, weld capacities, gusset geometry and fabrication tolerances are resolved first, so that every model we issue can be cut, welded and erected without queries or rework. We hold an authorised Tekla Diamond licence, which allows us to deliver fabrication-ready models and shop drawings to a consistent, internationally recognised standard for clients on any continent.

We serve every sector, and in particular four: petrochemical and EPC facilities across onshore and offshore oil & gas installations; bridges and wider infrastructure; residential, commercial and industrial buildings; and outsourced design and drafting for manufacturing and precision engineering. Each sector is governed by its own codes, load considerations and tolerance requirements, so we treat them as distinct engineering disciplines rather than one method applied uniformly across all of them. This sector-specific expertise, combined with an advanced software infrastructure spanning Tekla Structures, STAAD Pro, IDEA StatiCa, RAM Connection and SmartPlant 3D / Aveva E3D, allows us to deliver consistent, code-compliant engineering to clients worldwide.

  • Tekla-to-fabrication workflows incl. CNC/tube-laser export

How we work

Six platforms, one connected workflow

Analysis, connection design and detailing are run as a single pipeline — not six disconnected tools — so a change in one model shows up correctly everywhere else.

Modelling / BIM

Autodesk Revit

Federated structural and architectural models for clash detection, coordination and multi-discipline sign-off across EPC and building projects.

  • 01 Import architectural/MEP models and align grids & levels
  • 02 Build the structural model and run clash detection
  • 03 Issue coordinated, sign-off-ready federated drawings
Detailing Trimble Authorised Tekla Diamond Licence

Tekla Structures

Fabrication-grade steel detailing, connection modelling and shop-drawing generation, including direct DSTV/STEP export for CNC and tube-laser cutting. Delivered under our authorised Tekla Diamond licence, available to both domestic and international clients.

  • 01 Model members & connections to the analysis geometry
  • 02 Detail bolts, welds and fabrication tolerances
  • 03 Export shop drawings and DSTV/STEP files for CNC
Analysis

STAAD Pro

Full structural analysis and code-based design — gravity, wind, seismic and blast load cases — checked against IS 800, BS 5950, EC3 and AISC 360.

  • 01 Build the analytical model and apply load combinations
  • 02 Run gravity, wind, seismic & blast load cases
  • 03 Verify code checks and issue design summary
Connections

RAM Connection

Rapid connection design and capacity checks for standard shear and moment connections across large structural steel packages.

  • 01 Pull member forces from the analysis model
  • 02 Auto-size shear/moment connections to code
  • 03 Batch-check capacities across the full package
Connections / FEA

Mat3D

Finite-element verification of non-standard and complex joint geometries — tee-braces, gusset plates and combined-load connections — beyond code-table coverage.

  • 01 Model the joint geometry & applied load cases
  • 02 Run CBFEM finite-element stress verification
  • 03 Confirm capacity and issue the connection report
RCC Detailing

RCDC

Automated RCC design and detailing for slabs, beams, columns and footings, streamlining reinforcement drawings for residential and commercial structures.

  • 01 Import framing layout and design load cases
  • 02 Auto-design slabs, beams, columns & footings
  • 03 Generate reinforcement & bar-bending drawings
Connections / FEA

IDEA StatiCa

Component-based finite-element (CBFEM) verification of steel joints, base plates and complex connections beyond the scope of standard code-table checks.

  • 01 Rebuild the joint geometry with real member cross-sections & welds/bolts
  • 02 Apply governing load combinations from STAAD/analysis output
  • 03 Run CBFEM analysis, confirm utilisation & issue the connection report
Mechanical CAD

SolidWorks

3D parametric modelling of fabricated assemblies, brackets, lifting attachments and mechanical packages that interface with structural steelwork.

  • 01 Build parametric part & assembly models with mating constraints
  • 02 Run interference/motion checks and engineering drawings with GD&T
  • 03 Issue fabrication drawings and BOM for shop manufacture
Mechanical / Surface Modelling

CATIA

Advanced surface and assembly modelling used for complex mechanical/piping interfaces and large multi-body assemblies on EPC packages.

  • 01 Develop part & surface geometry to client-supplied standards
  • 02 Assemble and validate large product structures (kinematics/clash)
  • 03 Release associative drawings and neutral-format exports (STEP/IGES)
4D Planning & Simulation

Synchro 4D

4D construction sequencing that links the Tekla/Revit model with the project schedule to simulate erection sequence, logistics and site constraints ahead of time.

  • 01 Link the 3D model (Tekla/Revit/IFC) to the project schedule (P6/MS Project)
  • 02 Simulate erection sequence, crane access and site logistics
  • 03 Identify clashes/conflicts early and issue the agreed look-ahead sequence
Training & Certification

Software Training Programs

Structured, project-driven training on Tekla Structures, STAAD Pro, IDEA StatiCa, RAM Connection and SmartPlant 3D / Aveva E3D for engineers, students and corporate teams, with a certificate of completion issued by Sri Kandhan Engineering Solutions.

  • 01 Foundation-to-advanced modules on your chosen platform
  • 02 Hands-on exercises using real project geometry
  • 03 Assessment and certificate of completion on successful sign-off
Engagement sequence

From load case to lifting hook

A fixed sequence, because skipping a step is where fabrication queries come from.

01

Analysis & concept design

STAAD Pro modelling of the primary structure against governing load cases, with concept sizing for members, foundations and lateral systems.

02

Connection design

Every joint checked in RAM Connection or verified in Mat3D/IDEA StatiCa where geometry or combined loading falls outside standard code tables.

03

Coordinated modelling

Revit federation across structural, architectural and MEP to resolve clashes before a single shop drawing is issued.

04

Detailing & documentation

Tekla Structures shop and erection drawings, or RCDC reinforcement drawings for RCC scope, issued to fabrication tolerance.

05

Fabrication support

DSTV/STEP export and query resolution through cutting, welding and erection — the drawing set is supported, not abandoned, at handover.

Why Sri Kandhan

What a fabricator notices about our drawings

Connection-first modelling

Joints are designed before they're drawn, so geometry doesn't get discovered at the shop floor.

Multi-code fluency

Indian, British and American code bases run side by side for projects that answer to more than one authority.

Fabrication-aware export

Models built with CNC and tube-laser output in mind, cutting rework at the DSTV/STEP handoff.

One point of accountability

Analysis, connections and detailing tracked by one team, so revisions propagate instead of getting lost.

Global reach

Countries we serve.

We work to the code the project is governed by, in the time zone the project runs in. Delivery is worldwide.
