Subjective. Productivity continues to be an challenging subject and a dominant issue in the development sector, appealing cost savings and efficient using resources. Efficiency is one of the most crucial issues in both produced and producing countries. The developed countries are aware of the importance of economical growth and social welfare. The developing countries which face unemployment problems, pumpiing and resource scarcity strive to utilise resources and in this kind of a way to obtain economic growth and improve citizens' lives. Productivity is an issue of particular importance to assignments located in the Gaza Tape, as it is regarded as a newly-developed area, and a huge number of projects have already been planned intended for the near future. The goal of this research is to identify factors affecting work productivity inside building jobs, and to get ranking these factors according to their relative importance from a contractor's viewpoint. The research of forty-five factors regarded as in a survey indicates the main elements negatively impacting on labour efficiency are: materials shortage, not enough labour encounter, lack of labour surveillance, misunderstandings between work and superintendent, and sketches and specification alteration during execution. Keywords: productivity, labour, building assignments, improvement.

1 . Introduction Undoubtedly that building is a important activity inside any economic system; it influences, and is influenced by, the country's gross domestic product (GDP) (Cox ou al, 1998, cited in Madi, 2003). Given the uncertainties, managing is to deal with, the construction industry is a risky one. Although these hazards may be created from either external or interior factors, external factors have a greater affect on structure industry compared to the internal ones (Zhi, 1995). The construction sector in Middle east experienced some considerable growth inside the aftermath of 1967; their share of GDP increased from less than 9 % in 85 to a lot more than 23 % in 95. During that period the sector's contribution fluctuated in an way up long-run pattern bounded simply by 9 % and nineteen % from 1970 to 1980, through 15, 2 % and 23 % from 1989 to 95 (PECDAR, 1997). However , it appears that in 2005 the construction sector's contribution to the GDP was reduced to 9 % due to the second Intifada in Palestine (World Bank, 2005; PCBS, 2004). Due to increased demand from your first Intifada, and to cater to Palestinian returnees from the Gulf following the initially Gulf Conflict, the construction sector experienced a reliable increase coming from 1991 onwards. The 1994 peace process accelerated this increase, especially after the returning of many Palestinians with the Palestinian National Specialist (MAS, 2001). Expansion of construction actions has made numerous careers for qualified,

semi-skilled, and unskilled time. Fig you shows the distribution of the labour power within the development sector from 1997 to 2001 (PASSIA, 2002). Building construction is among the pioneer industries that accomplished high development rates over the last two decades, and played a crucial role in absorbing progressive injections in the Palestinian time force (PCBS, 2004). doze, 60 % mil novecentos e noventa e seis 15, 10 % 2001
