He will be joined by business minister Michael Fallon and a business delegation of 18 CEOs and senior executives from companies including Arup, Mott McDonald and Aecom.
Among the plans being announced by Clegg is that Hill International is to open a new Turkey and Central Asia regional office in early November as part of its efforts to secure contracts worth up to £250m.
The delegation members will hold discussions with their Turkish counterparts concerning possible new deals and business ventures potentially worth up to half a billion pounds.
“Turkey is Europe’s seventh largest economy and is one of the worlds largest markets,” said Clegg. “My main aim this week is to ensure that more UK firms can capitalise on the economic opportunities Turkey offers.
“We have an ambitious aim to double bilateral trade by 2015. It has increased by 40% since 2009 so we are making good progress towards the target, and this visit will bring us even closer.”
Aecom recently announced that they have been selected as project manager for the first phase of the US$2.2bn (£1.4bn) Bio Istanbul project. The company is in Turkey this week to investigate potential business opportunities in property development, transportation - including support for the forthcoming motorway privatisation programme - and in culture and leisure.
Mott MacDonald have been involved in projects in Turkey for over 20 years. Much of the company's recent work has been working as traffic, commercial, technical and environmental advisors on almost all of the private sector airport developments.
