This guide describes how large-scale labour-based infrastructure programmes, carried out by contract, should be developed. It introduces cost-effective, employment-intensive approaches to infrastructure works while exploring how socio-ecomic objectives such as employment, conditions of work and labour standards can be integrated into private sector programmes of this nature. Written to contribute to a policy of job creation and progress in developing countries, the guide discusses different options for private sector development. It examines the selection and participation of private contractors and consultants and looks at methods for ensuring the regular and timely payment of workers. It also explores appropriate and transparent contract systems, and examines contract bidding, tendering and reporting.
