The final version of "Conditions of Contract for Construction, Multilateral Development Bank Harmonised Edition" was posted yesterday on FIDIC's web site: http://www1.fidic.org/downloads/cons_mdb_gc_jun10_unprotected.pdf
The World Bank and the regional development banks (ADB, AfDB, EBRD, IDB), collectively know as the multilateral development bank (MDBs),
Last November agreed mandatory labour standards requirements for construction projects they finance. The specific language that the MDBs adopted is based on proposals made by BWI.

The chapter on labour requirements is on pages 24-28. The specific clauses that correspond to CLS requirements are 6.20 (Forced Labour), 6.21 (Child Labour), 6.23 (Workers' Organisations) and 6.24
(Non-Discrimination and Equal Opportunity). Article 6.23 states in part that, whether national law fully recognizes freedom of association or not, "the Contractor shall not discourage the Contractor’s Personnel from forming or joining workers’ organisations of their choosing or from bargaining collectively, and shall not discriminate or retaliate against the Contractor’s Personnel who participate, or seek to participate, in such organisations and bargain collectively."

The importance of Labour Standards in MDB-financed construction projects has grown as infrastructure has taken up in an increasing portion of the MDBs' financial support. In fiscal year 2009-2010, infrastructure projects made up 37 per cent of the World Bank's total financial commitments.
