COS / Design and build

For design and build: price and risk under control.

When you carry both design and construction, every pricing mistake comes out of your margin. COS links the bid price, budget, orders and real cost.

Built with our first construction partners in Croatia and Serbia.

Where it gets stuck today

01

Fixed price

The price is given early and the risk stays with you until handover.

02

Budget after contract

The contract price never becomes a budget and orders, so deviations show up late.

03

Cash flow

You cannot see in advance when money comes in and when it goes out.

What COS does for you

Example from the walkthrough

On site the paver actually does 132 m²/h instead of the planned 150. COS sees it in the diary and updates 14 formulas for the next bid.

03Management review

Management rates the tender and decides whether to go ahead.

Management scores the tender and the risk before the team starts work.

The team only works on tenders management believes in.

06Item estimate

Every BOQ item gets an estimate: materials, machines and labour.

Every item has an estimate: materials, equipment and labour.

Every item price is explained and checkable, down to the last hour.

11Bid price and submission

Price, margin and risk in one place, before submission.

Price, margin and risk in one place before submission.

The bid goes out calmly, with known risks and a checked margin.

12Contract, orders, stock

A won bid becomes the budget, orders and stock.

The won bid becomes budget, orders and stock.

What you bid is what you order and track.

20Cash and feedback loop

Cash flow ahead, and experience back into the formulas.

Cash flow by month and real cost back into the formulas.

The company learns from every site, and cash never comes as a surprise.
