Model
Enter the enquiry as geometry — span, bay spacing, eave height, crane and canopy — and the frame builds itself. No CAD seat, no draughting time before you can price the job.
Win the tender
Every PEB tender ends the same way: the lowest credible bid wins. mkaPEB runs the enquiry’s parameters through a real design, so the number you submit arrives with the building behind it.
The specification arrives as an architect’s DWG and a bullet list — spans, bay spacing, eave height, loads, design code. No engineering in the file: every fabricator prices the same list, and the lowest credible bid takes the job.
Estimation-only software stops at a figure you can’t submit. In mkaPEB the estimate is the full run — frame, code loads, analysis, connection design, and mkaPEB AI sizing every member. The optimizer tries 10,000+ real scenarios and hands back the 10–20 best combinations, lightest to heaviest. The number falls out of a real design, not a lookup.

The number goes in with every deliverable behind it, off the same model. An estimation-only tool hands you a figure; mkaPEB hands you a submission.
The AI already did the hard part — cost efficiencies nobody could calculate by hand. The number is lower because the steel is less, not the margin. When the client’s checker examines the building, the documents hold: the design behind the bid was real from the first hour.
Estimators, engineers, detailers — each rebuilds the same pre-engineered building in a different program. Choose your role to see mkaPEB in your terms.

Replaces the tonnage spreadsheet and rate card
Quote from an optimised frame, not a catalogue lookup. The optimizer sizes non-prismatic sections for the actual spans, bays and loads in front of you — the tonnage you bid is the tonnage the shop builds. When the enquiry changes, you re-run, not re-model. Winning the job doesn't start a rebuild.
10,000+ scenarios → the 10–20 best in ~3 minutes
The rule-based optimizer narrows the scenario space rather than fetching a stock section.
The numbers
Estimator / tender desk: your steps are 1 and 4 — geometry and loads in, an optimised tonnage out, before anyone commits a price.
Enter the enquiry as geometry — span, bay spacing, eave height, crane and canopy — and the frame builds itself. No CAD seat, no draughting time before you can price the job.
Wind, snow, seismic and live loads are built straight from your design code — the work you'd otherwise hand to a loads engineer, done and fully auditable.
The built-in analysis checks every member against the code — and ties out against SAP2000, the engine the client's checker already trusts.

This is the number you bid on. The optimizer narrows thousands of section combinations to the lightest code-compliant frame in about three minutes, so the tonnage in your quote is an engineered figure rather than a catalogue guess.
End plates, base plates and gussets are sized from the actual design forces — no over-welding, no rule-of-thumb, no field surprises that eat the job.
A BOQ and cutting list come off the same model, so the quote carries real quantities behind it — and if you win, nothing has to be rebuilt to start fabrication.
DWG to your CAD, DSTV/NC1 to your CNC cutting line, PDF for submittal. mkaPEB feeds the machines already on your floor — nothing to re-model between workflows.

Field Notes
Training sessions, project runs, and technical notes our team shares directly from practice — republished here rather than embedded, so the substance stays on the page.
Z and C purlin continuityOne of the biggest advantages comes when Z and C sections are designed as continuous members. Continuity lowers bending moments, allowing engineers to use lighter, more economical profiles instead of heavier hot-rolled sections. […] Because laps are simple and efficient, Z-sections remain the preferred option for continuous purlin and girt systems.
