How it works

How a job runs

Clear scope before any modelling starts, and you see progress while it happens.

G-002

  1. Send the files

    CAD, PDF, sketches or a point cloud, with your template and deadline.

  2. Quote within 24 hours

    A fixed price or hourly estimate, with a delivery date.

  3. Model with updates

    Progress shared every one to two days, so changes stay small.

  4. Delivery

    RVT in your Revit version, plus PDF and DWG exports.

First time working together? Start with a small trial task at a reduced rate and judge the result before committing to more.

Behind EYVAN

G-003

EYVAN is run by Ehsan Ahmadghondaghsaz, a building engineer in Milan with a Master's in Management of Built Environment from Politecnico di Milano. Years on construction sites shape how the models are built: they have to work for the people who build from them. The name comes from the eyvan, the vaulted hall that opens onto a Persian courtyard.

Two-storey load-bearing masonry building

Structural design · Turin, Italy · November 2026 · Revit 2027

Our own demonstration of a complete structural BIM workflow on a typical Italian palazzina: two storeys and an attic on a 12 × 9 m plan, solid-brick bearing walls, reinforced-concrete ring beams and lintels, 20+4 clay-block floors, a concrete stair and a timber roof. Modelled in Revit 2027 with a connected analytical model, loads and combinations to NTC 2018, then delivered as 11 A1 sheets in Italian, a preliminary calculation report, an IFC 2x3 file for structural analysis software and a bill of quantities. LOD 400 (LOD E, UNI 11337-4).

  • Structure: bearing walls modelled as structural walls with openings aligned floor to floor, ring beams, lintels, strip foundations, floors and stair, with the analytical model connected throughout.
  • Reinforcement: ring beams, lintels, foundations, stair and floors reinforced in Revit, 279 bars, with bar schedules taken straight from the model.
  • Timber roof: glulam ridge beam and C24 rafters with steel connections; 345 bolts and anchors modelled, including the ties between masonry and ring beams.
  • Design: loads and seismic action to NTC 2018 and Circolare 2019, the simple-building check, wall stresses and slenderness, ring beam, lintel, foundation and roof checks, all in an Italian calculation report. Every check passes.
  • Delivery: zero Revit warnings and zero clashes; the IFC was checked class by class before export, together with DWG sheets and quantities.
