Alfred McAlpine Work on major privately financed projects helped Alfred McAlpine increase contracting profits in 2001, according to results published last week.
Alfred McAlpine capital projects increased operating profits from £16.4M in 2000 to £18.1M in 2001, while the division's turnover increased from £308M to £335M.
Contracting margins outstripped those of most competitors at 6.9%.
Alfred McAlpine group operating profits rose from £60.6M to £63M, while turnover increased from £376.1M to £554M.
Carillion Costs of bidding for more public private partnership (PPP) projects hit Carillion in 2001.
As a result, operating profits made by the construction services division fell to £22.3M from £25.7M last year on turnover down from £1.49bn to £1.3bn.
Carillion said its contracting division's turnover fell because it was adopting a more selective approach to bidding. This was reflected in improved margins which rose from 1.9% to 2.4%.
Interserve Growing contracting profits underpinned a strong performance by Interserve in 2001.
The former Tilbury Douglas contracting business increased operating profits from £11.2M to £14.7M on turnover up from £450.4M to £537.8M.
Interserve group pre-tax profits increased from £34.2M to £39.3M. Group turnover increased from £880.4M to £1.243bn.
John Laing The former construction giant cemented its fall by reporting a £24.7M pre-tax loss for the year to 31 December, compared to a £5.7M profit in 2000.
Losses of £94.5M run up by its construction business combined with £33.6M costs incurred when Laing Construction was sold to O'Rourke last year offset improved operating profits in the rest of the business.
Amey Bidding for large scale contracts led to pre-tax losses of £18.3M in the year to 31 December, compared to a pre-tax profit of £27.3M in 2000.
Changes in accounting systems, meant Amey wrote off 'significant pre-contract and similar in-contract costs' and deferred an element of future income. But it claimed to have won nine jobs worth £1.9bn in 2001 and nine worth £922M in 2002, lifting orders to a record £4.3bn.
