Price & carbon analysis

From BoQ to a price / carbon comparison.

Before it goes out to tender, a bill of quantities has to be priced. At that stage every item has its price but none has an order-of-magnitude carbon figure, so substitutions are made by guesswork. Our price & carbon analysis provides this missing link and pinpoints the items where the gains are real.

A bill of quantities goes out to tender with its prices and without its carbon, even though both are decided on the same lines. We quantify both columns side by side, item by item, at a point when changing a material is still a matter of fine-tuning.

From a BoQ

Price & carbon analysis.

Measure the real impact of your project and target the gains your bill of quantities makes possible.

Every item compared in euros and in embodied carbon, with the substitutions that improve price and carbon, and the items that are missing compared with a complete specification.

What you receive
The file
Your bill of quantities enriched with average price, price range and embodied carbon, line by line. Returned within 48 to 72 hours.
The substitutions
Identified among biobased, low-carbon and reuse options, with the gain on each column.
The gaps
Flagged items: what is missing from the specification or does not hold up.
The analysis
Two pages: three sustainability trade-offs, three on economic and carbon performance, and what the former free up for the latter.
The stakes

Trade-offs at project scale.

What you save on one item can fund a decision elsewhere that weighs far more in carbon terms. Our analysis reads price and carbon together, which lets you weigh up these choices and identify the items that have a real impact on your project.

Costing the alternative.

Where an alternative exists, the report names it and quantifies it: a biobased, circular or low-impact option that replaces the original item, backed by technical data.

Finding gaps in the specification.

Our analysis checks your bill of quantities against what the site will actually require, and picks out missing or inconsistent items before the tender locks them in.

The steps
01
The BoQ
An Excel file, a set of tender documents or simply a list: five facade options are enough. No set format.
02
The figures
Each item is matched to its INIES code, then cross-checked against our price sources and the available EPDs. Average price, upper and lower bounds, embodied carbon.
03
The trade-offs
The substitutions that hold up, the gain they represent on each column, the flagged items. Your enriched file, and two pages of analysis.
The method

It flags missing items; it does not write the specification.

Our prices are market averages with their range, not quotes. The precision is that of an order of magnitude, which is the right level for making decisions at design stage. Our sources are documented.

Writing the specification and weighing trade-offs across a whole project fall under the project study.
