Expected award price

likely award for this notice, from its published estimate of €923,000
€655,330 to €923,000

Comparable awards in this country and sector came in at a median of 87% of their published estimate, half of them between 71% and 100%, based on 1,827 awards of the last 3 years.

Each award is compared with the estimate of the same lots, framework agreements excluded. A published estimate may include options and renewals, so an award under it is not always a discount.

What this buyer has paid before

Based on 103 comparable contracts this buyer awarded in this sector over the last 4 years.

One dot per award, on the day it was signed, sized by its value. A ring is an award with no published value.
