Consulting engineer and asset manager Parkman Group is to float on the stock exchange to raise funds for acquisitions.
Parkman wants to raise £10m by going to the City at the end of the month. Executive chairman Richard Archer, who led a management buyout 13 months ago, said the money would go towards acquisitions and financing contracts. The listing would also clear debt taken on after the buyout.
Archer said the group's future growth depended on increased infrastructure spending. The government wants to spend £180bn on transport over the next 10 years.
Archer said: "Government spending is driving our order book growth."
Parkman also recently moved into social housing after winning a contract to repair and maintain all Westminster council's social housing.
The company, founded in 1888, operates in the transport, construction, environment and water sectors. It has 1100 staff and 21 offices in the UK and Ireland.
