Merged company comprising Boxall Sayer, Denley King and Fletcher McNeill will be chaired by Roger Knowles
The firms have formed Baqus, a practice that will be chaired by JR Knowles founder Roger Knowles. JR Knowles was sold to Hill International last year.
The newly formed consultancy is seeking to list on the Alternative Investment Market in November. The move follows the recent announcement by QS Cyril Sweett that it is planning a listing in the AIM autumn, meaning the two firms will be the only QS companies listed on the stock market.
Baqus, which has a turnover of £7m and profit of £1m, will initially have a market capitalisation of £13m. This includes an expected £3m of cash to be generated by the flotation, which the firm plans to use to begin an expansion strategy.
