The government has appointed a senior executive from Bechtel to lead the government body overseeing the 2012 Olympics.

Jeremy Beeton will leave Bechtel to become director general of the 50-strong Government Olympic Executive.

The post was created because of confusion over the Games’ expanding budget.

The Olympic Delivery Authority has invited bids for the construction of Olympic sailing facilities at Weymouth and Portland National Sailing Academy, and Osprey Quay in Dorset.

The contract is to build a £150m slipway, a boat parking area, lifting facilities, moorings and a wave protection structure.
