The purpose of this paper is to prioritize the vital tools/techniques for the effective implementation of the last planner system (LPS) in the cross-cultural setting of a developing country, i.e. Gaza Strip. Besides, the potential benefits of implementing LPS are prioritized.
The significant techniques and likely benefits of LPS implementations were identified through comprehensive literature, followed by their verification through a pilot study. The quantitative data were collected using a questionnaire survey from 89 companies, operating in the Gaza Strip construction industry. The relative important index was calculated for prioritizing the significant tools/techniques (16) which support the effective LPS implementation, and highlighting the potential benefits (10) achieved through LPS implementation.
The results showed that the “use of visual devices to spread information in the construction site,” “attendance of key actors” and “look ahead plan” are the most important tools/techniques supporting LPS implementation. The top three potential benefits of implementing LPS include: “allows a better understanding of the program control,” “maximizes the co-operation and confidence among team members” and “allows the manager to better visualize the work program.” To prevent any waste in project time and to ensure the material supply and continuity of works, the study recommends advance supply and storage of demand materials, and early availability of the shop-drawings for acceptance by the superintendent.
The study’s findings are expected to guide the key construction stakeholders to prioritize their energies toward effective LPS implementation in the Gaza Strip.
Though this study pertains to Palestine, its methodology can be generalized in other countries and regions, having a similar work environment, after making necessary cultural adjustments.

Subcontractors play a significant role in the Palestinian construction industry as about 90 per cent of the work is performed by subcontractors. The main objective of this paper is to identify and analyse the major problems which exist between the contractors and subcontractors in the construction industry in the Gaza Strip.
A questionnaire was designed to elicit contractors' and subcontractors' viewpoints regarding the most important causes of problems that affect the relationship between them. A total of 53 problems were identified based on a literature review, a pilot study was considered in this study and was listed under five groups. A total of 150 questionnaires were randomly sent to contractors and subcontractors. The respondents had extensive experience in the construction industry with average working experience of 20 years. The questionnaire was validated by the criterion‐related reliability test that measures the correlation coefficients between the factors selected for in each group and for all groups as one entity, and structure validity test (Spearman test).
The result of the survey indicated that, assigning part of the works to new subcontractor without informing the original subcontractor, contractor's financial problems, delay in contract progress payments, non‐adherence to the conditions of the contract, non‐adherence of the subcontractor to the time schedule, and lack of construction quality work were the most important causes of interface problems, while involvement in several projects with the contractor at the same time, weather conditions, and geological problems on site were considered as trivial causes of potential interface problems. Spearman's rank correlation tests showed that there are no differences in the viewpoints between contractors and subcontractors.
The research findings might assist practitioners to focus on major problems which have existed between the contractors and subcontractors in the construction industry in their present and future projects. By eliminating or minimizing these problems, subcontractors are encouraged to contribute significantly to the capital risk, resources, managerial effort, and business expertise supporting the largest industry in Palestine. The paper would be valuable for all academics and industry professionals involved in construction business in general.
