Construction firm Carillion is attempting to persuade rival Balfour Beatty to go-ahead with the takeover.
In a statement released by Carillion today, the firm said there is "powerful strategic logic" in a merger.
Balfour Beatty has already turned down two takeover proposals by Carillion, however the firm has until 21st August to make a final offer.
Carillion said as a direct result of the merger, the cost-base of the combined group could be reduced by at least £175 million per annum by the end of 2016 and that earnings would consequently be significantly enhanced from that year.
Today, Carillion also reported a 3% increase in first-half underlying pretax profit to £75.9 million.
Carillion said its full-year targets for revenue growth remained unchanged "despite markets remaining challenging".
