Kier returned to the summit of the annual contractors’ league after taking the monthly title with a strong showing in July.
The contractor was top for the month through sheer weight of numbers rather than any one big-ticket win, having secured 44 deals over the period, according to Glenigan.
Vinci was close behind in second for July, winning seven contracts including a £120m scheme for the London School of Economics.
Thales took third with the single biggest deal confirmed in the month: a £600m signalling package for London Underground.
Interserve was eighth having won another of the major contracts sealed in July: the £200m redevelopment of Stanford Hall near Loughborough into a defence rehab centre for BS Stanford.
Buckingham meanwhile took a £70m deal to build a new stadium for Brentford FC, putting it 13th for the month.
There were also significant shifts in the annual contractor table, as Kier’s winning performance in the latest monthly league saw it reclaim the summit for the 12 months to July, leapfrogging Laing O’Rourke.
Balfour Beatty’s solid activity in July helped it close the annual gap to second-placed Laing O’Rourke, while Vinci’s similarly impressive recent showing saw it climb from 12th to sixth.
