This paper provides a conceptual framework to enhance productivity, where international professionals and contractors are involved in construction projects.

The construction industry in Sri Lanka is generally challenged by sharp practices amongst its variety of indigenous and foreign professionals and contractors, often leading to low productivity. Productivity is an index for evaluating efficiency and performance of construction projects, and the current research investigates the factors influencing productivity. The aim is to recommend strategies that could mitigate the negative effects of low productivity in Sri Lanka. The study provides a conceptual framework to enhance productivity, where international professionals and contractors are involved in construction projects.

A questionnaire survey was administered to a total of 40 local and international construction professionals who currently work in Sri Lanka as engineers, quantity surveyors, architects, project managers and construction administrators. The objective is to determine the significant factors influencing productivity and strategies for improvement. 33 out of 40 positive responses were analysed for the study. The findings indicate 16 most significant factors including: level of experience, level of knowledge in new advanced technology and construction techniques, low levels of on-site safety and government policies, different lifestyles and cultural behaviors. The results suggest that implementing strategic approaches that could enhance on-site safety policies and procedures, use of advanced technology, improve and encourage team work would positively impact on productivity of construction projects in Sri Lanka.
