The civil engineering AI workbench

Built for people who build real things.

Concrete mix designs, life-cycle assessments, geotechnical parameters and priced bills of quantities — drafted by AI, confirmed by you, computed by deterministic code.

Studio 01 — Mix Design

A mix that holds up, in minutes.

Describe the element, the exposure, the target strength. Miksir walks the code tables — ACI 211, EN 206, TS 500, BS 8500 — and returns proportions with a full compliance checklist.

  • Conversational design with clarifying questions, not forms
  • Exposure-class requirements resolved automatically
  • Batch quantities from lab trial to full truck, as PDF

TRIAL BATCH — C30/37 · XS2

Studio 02 — LCA

Know your carbon before you pour it.

Life-cycle assessment for any material or product, aligned to ISO 14040/14044. Track GWP and embodied energy, compare alternatives, and export a report your client can audit.

  • Cradle-to-gate GWP per m³, per mix, per project
  • Shareable data-collection forms for suppliers
  • AI-written narrative sections — figures stay computed

GWP — CRADLE TO GATE

Studio 03 — Geo

From field blows to design parameters.

Paste SPT or CPT field data and get corrected values, soil classification, cohesion, friction angle, bearing capacity and unit weight — every correlation cited, every step shown in the PDF.

  • Energy, overburden and equipment corrections applied in code
  • Published correlations, named and referenced per result
  • Footing bearing-capacity checks with your geometry

BH-01 — SPT PROFILE

Studio 04 — BOQ · New

Drawings in. Priced BOQ out.

Upload structural drawings. AI extracts every column, beam, slab and footing — then stops. You confirm each value against the sheet before a single quantity is computed, priced or exported to Excel.

  • Concrete, rebar and formwork calculated by formula engine, never AI
  • Anything unclear becomes a question, not a guess
  • Masonry and roofing entered directly, priced in the same bill

Why engineers trust it

One rule runs every studio.

RULE — 01

AI drafts

Vision models read your drawings and data. Language models write your narratives. They propose — extraction tables, parameter suggestions, report prose — and nothing more.

RULE — 02

You confirm

Every extracted value is reviewed against the source sheet before it counts. Low-confidence reads become specific questions. Unconfirmed data never reaches a calculation.

RULE — 03

Code computes

Quantities, corrections, compliance checks and totals come from deterministic formula engines you can audit — the same input gives the same answer, every time.

What this replaces

Four subscriptions. One bill you'll actually like.

Every Miksir studio replaces a tool sold separately — and expensively.
