Design and engineering consultancy Scott Wilson said interim results are likely to be ahead of market expectations.The group said the performance of its joint ventures has been better than expected and its share of profits from the jointly owned operations is now expected to be £2m or more.Elsewhere in the group, profitability is benefiting from the new management structure and the group's involvement in the higher growth market sectors identified in its business plan.'This is demonstrated by a number of recently reported project wins including major design packages for Crossrail, the Hong Kong MTR, the Mersey Tidal Barrage Study and more recently the £8 million Odra River Basin Flood Study in Poland,' the company said in a pre-close statement covering the 26 week period to the end of October.
