Baugrund Durch die zusätzlichen Baugrundaufschlüsse wurde festgestellt, dass sich die Baugrundschichten im Vereisungsbereich als deutlich komplexer erweisen. Diese zeigt sich insbesondere in der Kornverteilung, der insitu-Dichten sowie der Wassersättigung. Dies ist im Hinblick auf die Auswirkung auf die Frostkörperbildung zu beurteilen, um ein sicheres Bauen zu ermöglichen. Diese Beurteilung kann nur durch den Vereisungsgutachter in enger Abstimmung mit dem Baugrundgutachter erfolgen. 2. Forderung aus dem Planfeststellungsverfahren Durch das Eisenbahn-Bundesamt, welches als Planfeststellungsbehörde fungiert, ist am 26.01.2026 ein zusätzliches Zwischengutachten bzw. ein Zwischenbericht gefordert worden. Der daraus resultierende Mehraufwand fasst bereits die Statik und die Frostkörperentwicklung bzw. deren Lage, für die aktuell noch nicht alle Untersuchungsergebnisse vorliegen. Zudem können sich Änderungen aus etwaige Umplanungen ergeben, was mehrfache Arbeitsgänge und vertiefte Abstimmungen mit beteiligten Parteien erforderlich macht. An den vertraglichen Planungsgrundlagen der ABS und NBS ergeben sich keine Änderungen.</efbc:ReasonDescription></efac:ChangeReason></efac:ContractModification><efac:NoticeResult><!--BT-161-NoticeResult (Order: 02)--><cbc:TotalAmount currencyID="EUR">0</cbc:TotalAmount><efac:LotResult><!--OPT-322-LotResult (Order: 02)--><cbc:ID>RES-0001</cbc:ID><efac:LotTender><!--OPT-320-LotResult (Order: 02)--><cbc:ID schemeName="tender">TEN-0001</cbc:ID></efac:LotTender><efac:SettledContract><!--OPT-315-LotResult (Order: 01)--><cbc:ID schemeName="contract">CON-0001</cbc:ID></efac:SettledContract><efac:TenderLot><!--BT-13713-LotResult (Order: 01)--><cbc:ID schemeName="Lot">LOT-0001</cbc:ID></efac:TenderLot></efac:LotResult><efac:LotTender><!--OPT-321-Tender (Order: 02)--><cbc:ID>TEN-0001</cbc:ID><cac:LegalMonetaryTotal><!--BT-720-Tender (Order: 10)--><cbc:PayableAmount currencyID="EUR">0</cbc:PayableAmount></cac:LegalMonetaryTotal><efac:SubcontractingTerm><!--BT-773-Tender (Order: 05)--><efbc:TermCode listName="applicability">not-known</efbc:TermCode></efac:SubcontractingTerm><efac:TenderingParty><!--OPT-310-Tender (Order: 01)--><cbc:ID schemeName="tendering-party">TPA-0001</cbc:ID></efac:TenderingParty><efac:TenderLot><!--BT-13714-Tender (Order: 01)--><cbc:ID schemeName="Lot">LOT-0001</cbc:ID></efac:TenderLot><efac:TenderReference><!--BT-3201-Tender (Order: 01)--><cbc:ID>2023879685</cbc:ID></efac:TenderReference></efac:LotTender><efac:SettledContract><!--OPT-316-Contract (Order: 01)--><cbc:ID>CON-0001</cbc:ID><!--BT-1451-Contract (Order: 02)--><cbc:AwardDate>2023-06-01+02:00</cbc:AwardDate><!--BT-145-Contract (Order: 03)--><cbc:IssueDate>2023-06-12+02:00</cbc:IssueDate><efac:ContractReference><!--BT-150-Contract (Order: 01)--><cbc:ID>CON-0001 - Dr.-Ing.
