Foreign construction firms dominate the major projects in most developing countries as a result of deficiencies in indigenous construction capacity. A plethora of measures have been formulated and implemented to promote development of domestic contractors in these countries, but most attempts have achieved little success. This paper, arising from a larger study on management training needs of contractors in Nigeria, describes findings on constraints on indigenous contractors' performance in the Nigerian industry. Contractor-development programmes perceived as relevant and appropriate to improve their performance in the industry are also reported. The views of indigenous contractors and professionals were compared. There was a strong agreement between both groups on the major constraints in the industry and on the measures perceived as most important for the development of Nigerian contractors. Problems emanating from the business environment were generally perceived by both groups as the most severe constraints. Contractor-development programmes, perceived as very important by both groups, are also the measures required to ameliorate the most important constraints identified: obtaining interim payments, uncertainties in supplies and prices of materials, inadequate access to capital, plant and equipment. Contractor development is inevitably an integral part of a construction industry development programme, given the nature of constraints and development needs emphasized by both groups. The focus therefore should be on establishing a comprehensive programme for the development of the construction industry. More attention should be placed on contractor training to promote management development of trained construction professionals, now emerging as the new crop of construction entrepreneurs.
