MezzEstim8 is a web-native quoting platform for UK mezzanine and steel structure specialists. Type the dimensions or drag a footprint, set the imposed load, and the engine sizes UB columns, UC beams and MetSec joists from a validated UK catalogue — every selection is run against the BS 5950-1:2000 checks an engineer would review.
The output is a buyer-ready proposal you print, attach, and email. No CAD plugin, no per-seat licence, no Tuesday-morning installer.
Built for the day a customer phones in and you want to be the first quote in their inbox.
Engineering you can hand to a chartered engineer.
Every member sized against BS 5950-1:2000 — bending, shear, deflection, buckling, vibration. Calc pack prints as a clean A4 review document.
Buyer-first, by design.
A branded proposal with a hero render, three tiers, and a customer-facing PDF — not a CAD screenshot pasted into Word.
Live 3D viewer 
The mezzanine in their building, before they have built it.
Drop the host warehouse photo behind the model. Columns, beams, joists, deck, handrail and posts rebuild as you change inputs.
WHAT YOU GET ON LAUNCH
Six features. Everything in this list is real.
No placeholder buttons, no "Pro tier coming soon" footnotes. We would rather ship six features that work than thirty that do not.
- 01
Footprint sketcher
Type the plan dimensions, drag on a 0.5 m grid, or set up an L-shape, U-shape, or interior services hole. The bay grid auto-fits the floor — no overhanging columns, no maths.
- 02
Loading & spec wizard
Imposed-load presets (2.4 / 4.8 / 7.5 / 12 kN/m²), eaves and floor height, deck and joist centres, beam-restraint condition. Sensible defaults you can override.
- 03
BS 5950 section engine
Picks the lightest UB primary beam, UC column, and MetSec C-joist that passes every check: bending, shear, deflection (span/360 imposed, span/200 total), axial compression, lateral-torsional buckling, and a SCI P354 vibration heuristic. Every check shows the clause, the working numbers, and a utilisation ratio.
- 04
Live 3D viewer
A real Three.js parametric model — columns, beams, joists, deck, handrail and posts rebuild as you change the inputs. Drop a host warehouse photo behind the model so the buyer can see the mezzanine in their building.
- 05
Branded buyer proposal
Three tiers (Standard / Recommended / Premium), customer logo, hero render, scope of works, line-item costing, and a signature line. Save as PDF, attach to email, send. Web link and signature pad are upgrades on the same artefact.
- 06
Estimator override view
Every line item — section choice, rate, margin, fit-out, fire protection, design fees — is editable. The 3D model and the proposal stay in sync.

Bending, shear, deflection, buckling, vibration.
Every clause shown.
Every member sized against BS 5950-1:2000 with section properties from the SCI Blue Book and MetSec technical manual. Every check shows the clause, the working numbers, and a utilisation ratio.
HONEST ABOUT V1
What MezzEstim8 is not.
Every UK fabricator has been burned by software that promised more than it shipped. So here is the deliberately blunt list of things V1 is not.
-
Not a stamped design.
Every output is a draft for chartered engineer review. Connection design, foundations, fire engineering, vibration in detail, and disproportionate-collapse checks are out of scope and must be signed off externally.
-
Not a CAD package.
No DXF/IFC export at launch — that is a V2 module. MezzEstim8 lives between the phone enquiry and the engineer; CAD detailing is a separate job.
-
Not a fabrication MRP.
No production scheduling, no shop-floor cut lists. Pair it with StruMIS or your existing workshop system.
-
Not a multi-tier wizard.
Single-storey only at launch. Multi-tier and curved walls are a roadmap item.

Live cost breakdown, line by line.
Estimator override on every rate, margin, and fit-out item. Connection hints for engineer review. Outputs to a printed calc pack, a shareable web link, or a three-tier branded proposal.
WHY WE ARE BUILDING THIS
UK mezzanine quoting is dominated by tools built for the estimator, not the buyer.
MultiSUITE Mezzanine is an AutoCAD plugin — your estimator runs four separate licences and the buyer gets a PDF that looks like a 2010 CAD print.
StruMIS owns the back office but has a 2010-era desktop UI and no customer-facing artefact.
Hi-Level built IQD Pro in-house, in ten years, for a million pounds. Nobody else can.
MezzEstim8 is the platform your salesperson, your customer, your engineer and your fabricator all share — web-native, branded, and shipped as a service. The buyer gets a polished proposal in their inbox before MultiSUITE has finished loading AutoCAD.
WHO IT IS FOR
If you spend more than two hours per quote re-keying a footprint between AutoCAD, Excel and Word, this is for you.
- UK mezzanine specialists — Avalon, Stormor, Apex, Premier, CICS, Mezz Floors UK, and the ~120 active companies in the same bracket.
- Steel fabricators with mezzanine divisions — anyone quoting single-tier industrial mezzanines for warehousing, light industrial, retail back-of-house, or office fit-out.
- Independent estimators running multi-client work who want a single tool for sketch → calc → proposal.
PRICING
Included in your SteelEstim8 subscription.
£210/month (incl. VAT) covers the whole platform — SteelEstim8 for portal frames, MezzEstim8 for mezzanines, LoadEstim8 for member sizing, and every product as it ships next. One subscription, the whole family. No add-on fees, no upgrade decisions.
FAQ
The honest answers.
- Is the engine BS-compliant?
- The selection logic uses BS 5950-1:2000 with section properties from the SCI Blue Book / P363 and the MetSec technical manual. Every output is a draft for chartered engineer review — never stamped.
- Will it replace my engineer?
- No. It replaces the spreadsheet your estimator keeps in his head. The engineer reviews, stamps and signs off — same as today, just from a cleaner draft.
- Do I need to install AutoCAD?
- No. Browser-based. Works on any modern Mac or PC. Tablet support is on the roadmap but not at launch.
- What about CAD output?
- DXF/IFC export is a V2 module. V1 covers sketch → engine → proposal. If you need detailed shop drawings on day one, pair MezzEstim8 with your existing CAD workflow.
- Can my customer sign on the proposal?
- Yes — there is a signature line for printed/email PDF sign-off, and a web-link version with an in-browser signature pad. Both are real on launch.
- Is my customer data shared?
- Per-tenant cloud sync with bcrypt-hashed passwords, JWT auth, and SHA-256 IP hashing for buyer privacy. Your rate book, brand library, and saved quotes are yours.

First fifty UK fabricators get founder pricing for life.
And a direct line to the team building it. We need feedback from real estimators before V1 ships, and we will pay for that with permanent pricing.
