The amended guidelines are the product of "inclusive negotiations," Évosz said.

The association added that it has recommended a price indexing system to the Public Procurement Authority that could be used to manage price changes.

Association chairman László Koji noted that public sector orders account for about 60% of construction companies' business.

Évosz said prices in "a large part" of contracts may need to be rethought in the light of significant building material price rises in 2021 and 2022.

Construction companies can't carry the burden of risks related to price increases and higher costs alone, the association added, pointing to the impact of the war in Ukraine, dearer energy and the weaker forint on prices.

The guidelines for public sector orders may also be applied to home construction and renovation contracts, the association said.
