Dataset for material logistics on construction sites.

Data in this article describes logistics management on construction sites in Abuja, Nigeria. Data was elicited from 55 construction professionals comprising of Architects, Builders, Civil Engineers, Project Managers and Quantity Surveyors. The Data set in this study consists of responses on: factors affecting material purchase on construction sites, factors affecting accuracy of material delivery, challenges encountered during material delivery, benefits of material delivery on construction sites and methods of forecasting material demand on construction sites. This article provides insight into logistics management on construction sites in Nigeria and it can be a useful guide for similar research in other contexts.

Experimental design, materials and methods

The data in this article was generated by means of a cross sectional survey of construction professionals in Abuja, Nigeria. Previous researchers [1], [2], [3], [4], [5], [6], [7], [8] used similar approach to obtain empirical data from respondents. The questionnaire was adapted from similar previous studies [9], [10], [11], [12], [13], [14] and modified. The questionnaire was divided into 6 sections. Section A was used to obtain questions about material purchase on construction sites. Section B covered questions on material handling. Section C had questions that focused on accuracy of material delivery. Section D included questions about the problems encountered in logistics. Section E had questions which probed for the benefits of logistics management. Sections A to E were based on a 5-point likert scale type question with 1= not important, 2 = slightly important, 3 = not sure, 4 = important, 5 = very important. Section F was used to obtain demographic information about the respondents. Seventy questionnaires were distributed to Architects, Builders, Civil Engineers, Project Managers and Quantity Surveyors on a simple random sampling basis. Out of the 70 questionnaires distributed, 55 were returned and found suitable for analysis. Data was analyzed by means of Statistical Package for Social Sciences (SPSS) Version 22.
