SYDNEY, Aug 22 (Reuters) - Australian construction company CIMIC Group CIM.AX said on Monday it had started court proceedings in the United States against Chevron Corp (NYSE:CVX) CVX.N and KBR Inc KBR.N , seeking as much as A$1.86 billion ($1.42 billion) regarding a dispute over the jetty at the Gorgon LNG project in Western Australia.
CIMIC was commissioned to build the jetty there in 2009 and issued a notice of dispute regarding the work in February, following a disagreement over changes to the project.
The company said then that it was entitled to A$1.86 billion for the work.
"Negotiations under the contract continue," CIMIC said in a statement on Monday.
"The commencement of the proceedings has no effect on the negotiation process or CIMIC Group's entitlement to the amounts under negotiation," it added.
