Violation

The construction company, in their business evaluation application submitted on February 17, Reiwa 7, reported higher contract amounts for construction projects undertaken from multiple public sector prime contractors than the actual contract values. Additionally, in their application submitted on August 7, Reiwa 7, for the same evaluation, they falsely recorded a construction project contracted from a prime contractor in Osaka Prefecture as a general building project, despite it being a demolition work. They removed the term 'removal' from the project description and overreported the contract amount, which constitutes false documentation differing from the facts.

Cause of action

当該建設業者は、令和７年２月17日付けで行った経営事項審査申請（経営規模等評価申請・総合評定値請求）において、複数の公共発注の元請建設業者より請け負った建設工事について、実際の請負契約額よりも高い金額を記載した。 また、当該建設業者は、令和７年８月７日付けで行った経営事項審査申請（経営規模等評価申請・総合評定値請求）において、大阪府発注の元請建設業者より請け負った建設工事について、現実には「解体工事」に当たるにもかかわらず、「建築一式工事」の工事経歴書において、工事名から「撤去」を削除したうえで、その請負金額を過大に計上するなど、事実とは異なる虚偽の記載をした。
