Cost estimates and tender prices, before it is builtItemised. In writing. Justified.

Is it worth it, does it fit the budget, what will it cost? From screening to tender price, we tell you what the figure is made of, what the risks are, what is not included, and how long it is valid.

Then, the work

Transparent preparation.

Five short topics: how we help, how we work, the four steps, the example programs, and who is behind them.

Services

How we can help

01Is the plot or property worth it?A desk-based screening before you spend money on design.

What you receive

  • A short decision-support report.
  • A comparison of the options with order-of-magnitude costs.
  • A list of assumptions and gaps.

What we need

  • The plot details.
  • Your concept or brief.
  • The budget.
02Will it fit the budget?An early cost estimate before the design is complete. As a range: low, expected and high value.

What you receive

  • A range estimate by trade.
  • A list of assumptions.
  • A list of the largest cost items.

What we need

  • Your concept or sketch design.
  • The budget.
03The design is incomplete or contradictory.An itemised bill of quantities from the drawings. We list what is missing or contradictory.

What you receive

  • An editable bill of quantities.
  • A source column for every item.
  • A list of gaps and queries.

What we need

  • The drawings.
  • The technical specification.
04The tender deadline is tight.Tender pricing for contractors, based on the tender documents and the unpriced bill of quantities. You submit the bid in your own name.

What you receive

  • A priced bill of quantities in the format of the tender documents.
  • A list of clarification questions for the tendering party.
  • A risk list to support your decision.

What we need

  • The tender documents.
  • The unpriced bill of quantities.
  • Your own price levels, if available.
05The bids vary widely.We set contractor bids side by side, item by item, normalised to the same scope.

What you receive

  • A comparison table.
  • A list of differences, with explanations.
  • Questions you can put back to the bidders.

What we need

  • The bids, itemised if possible.
  • The tender documents.
06There is a dispute over extra works.We compare them item by item with the contract scope. This is a professional opinion, not legal advice.

What you receive

  • A comparison with the contract scope.
  • A list of differences, with explanations.

What we need

  • The contract and its appendices.
  • The disputed items.

How we work

How we work.

A clear workflow: itemised figures, a source next to every line, and one responsible professional at the end.

  • Itemised
  • With sources
  • Accountable

What we avoid

  • A single total with no reasoning
  • Terms that stay verbal
  • Blurred responsibility at the end

What we keep to

  • Itemised breakdown, a source on every line
  • Recorded terms and validity
  • One professional checks and is responsible

Five steps in the workflow

  1. CollectWe pull the line items from the drawings, the tender pack and the quotes.1
  2. CompareWe bring options to the same scope so they can be compared.2
  3. CalculateQuantities and ranges with our own tools, and AI support where it helps.3
  4. CheckI check every result as a professional. The responsibility is mine.4
  5. DeliverWith reasoning, sources, validity, and what is not included.5

We record

  • the price and the price-level date
  • what it is made of, and where the data comes from
  • the risks and the assumptions
  • what is missing, and what is not included
  • how long it is valid, and under what conditions

We do not take on

  • site visits: we work from the data you send
  • a contractor price guarantee: the figure is a professional estimate
  • legal advice: variation comparisons are a professional opinion

Process

Four steps.

  1. 01We review your documentsBased on the documentation available: drawings, tender documents, an unpriced bill of quantities, photos or a short description.
  2. 02We confirm the scopeWhat we take on, by when, and what information is still missing.
  3. 03We calculate it item by itemWith the source stated next to every line.
  4. 04We hand over the resultWith the reasoning behind every figure. On request, we also go through it in a Teams video call.

Our tools

Example programs, one workflow step each.

We built the three programs below as examples: each one can replace a single step in a workflow. What we offer companies goes further: we build AI-assisted workflows for faster, more precise work.

House cost estimator, detail (Hungarian-language interface): the estimated total cost as a range with low, calculated and high values, using the default inputs.

01 · Cost estimating

House cost estimator

Estimates a family house from the basic data, the structure, the level of finish and the room schedule, broken down by trade, with a schematic floor plan and three structural variants of the same house.

What you get: a range, not a single figure, with a derivation you can follow line by line and a list of what the estimate does not include.

Concrete and foundation calculator, detail (Hungarian-language interface): concrete to order, truck mixer loads and reinforcement weight, using the default inputs.

02 · Foundations

Concrete and foundation calculator

From the dimensions of strip, raft and pad foundations it calculates indicative concrete volume (m³), reinforcement weight, formwork area and the number of truck mixer loads; unit rates and output norms are editable.

What you get: an itemised breakdown and a material order list you can copy to the clipboard, for guidance only: it does not replace the structural design.

Construction schedule generator, detail (Hungarian-language interface): the Gantt view of the phases for the first months, using the default inputs.

03 · Scheduling

Construction schedule generator

From the building type, the structure, the floor area, the start date and the working pattern it produces an order-of-magnitude schedule in 14 phases, in a Gantt view, allowing for the winter shutdown.

What you get: the dates of the start, completion and main milestones (foundations complete, structure complete, weathertight, handover), as CSV or printed.

The tools give indicative results: not a quotation, not a bill of quantities and not a construction design. Every result is checked by a professional.

About us

Csaba Major · AI specialist, construction

I am Csaba Major. I work as an AI specialist with construction expertise: I build AI workflows and my own AI tools for construction.

By original profession I am a building construction technician with 10+ years in construction. That expertise is my edge: I know what to ask on a drawing set, and what is missing from a quote. AI agents speed up the research, the comparison and the calculation; I check every result as a professional and take responsibility for it.

How long does it take?
It depends on the scope. In our reply to your first email we confirm in writing when we can deliver.
Which documents do you need?
The documentation available: drawings, technical specification, tender documents, an unpriced bill of quantities, photos or a short description. If anything is missing, we will let you know.

Contact
