English Abstract

This research examines the factors affecting the productivity of excavation works for construction projects in Jordan.

These factors would suspend several works intended to be carried out for a construction project, and accordingly would increase the cost and time required to complete it.

After general reviewing previous global studies related to the above factors, and also after monitoring the productivity of excavation works related to five case studies (construction projects) in Jordan; a questionnaire was designed focusing on on the most important factors affecting the productivity of excavating works in Jordanian construction projects.

80 copies of this questionnaire were distributed to a number of consultants, project managers and contracting engineers.

However, 70 copies of the questionnaire were received, of which 15 were excluded from the analysis (due to their incomplete information).

Accordingly, 55 questionnaire was adopted to be analyzed in this research.

The collected data was analyzed using SPSS software in order to evaluate these factors and arrange them according to the importance sequence for each factor Based on the results of the questionnaire analysis, it was concluded that there are set of major factors that affect the productivity of excavation works in construction projects in Jordan.

According to the priority order, the first factor was the "Types and readiness of the excavation machines", followed by (in descending order) "Geological nature of the site", "Project site investigation", "Technical expertise specialized in carrying out excavation works", "Financial liquidity and the payment of dues", "Consulting experiences supervising the excavation works", "General conditions surrounding the project site", "Infrastructure of the project site", and "Environmental conditions surrounding the project site".

Therefore, to raise the productivity value for an excavation at a particular project without affecting the cost and time required for implementation, it is recommended to consider the above priority regarding the factors influencing the productivity, and focussing on employing those having a good experience in the implementation of excavation works, and who have the ability to perform the necessary maintenance for the machines in the event of sudden breakdowns during the excavation work, considering the periodic maintenance for the machines used in the excavation work at the project site.

It is also recommended to make the full payements for those working in excavation works according to the scheduled dates and agreements, Finally, it is recommended to follow the latest technologies that are used to deal with problems in the implementation of excavation works in construction projects.
