The low-level application of digital tools and information systems in construction implies that many projects cannot meet modern requirements and standard of work of advanced industries. This study adopts a practical and diagnostic approach to identify key attributes and implementation processes of information systems in construction and logistics. To have triangulation of knowledge, a three-step methodology is adopted. Initially an exploratory analysis of previous literature is performed. Secondly a diagnostic analysis of IS applications in construction is achieved by case studies. Finally, expert interviews are performed to examine and consolidate the findings. The study illustrated practical and innovative applications of low-cost digital tools in IS development and created a framework for documentation of these discrete and mostly unshared practices. It is recommended that the construction sector should embrace more advance technologies to minimise human intervention and enhance real-time capabilities. The practicality of how different low-cost and off-the-shelf tools and digital platforms can be combined is discussed and demonstrated. The study provides a clear distinction for practitioners and academics as to what is being practiced in comparison to the dominant theories.

Motivating Factor

Contingency amounts are allocated in the construction projects to deal with uncertainties arising during the projects. Contingency amounts are usually estimated traditionally by simply adding a percentage of the estimated contract amount. However, the traditional system of contingency estimation is heavily criticised as ineffective due to several reasons. Therefore, this research focuses on evaluating the level of accuracy of current contingency estimation techniques in the Sri Lankan context. This study adopted a mixed-method research approach. Empirical data were collected using expert interviews and questionnaire survey. Data collected from the expert interviews were analysed using manual content analysis. Descriptive statistics and inferential statistics were used to analyse the questionnaire survey data. Findings revealed that inexpensiveness is the highly motivating factor for the rigid usage of the traditional method to estimate contingency in the Sri Lankan context. Estimated contract amount, procurement method, payment method, and type of client were identified as highly influencing factors in contingency estimation. Finally, the hypothesis test of this study revealed that the traditional contingency estimation is ineffective. Since the traditional contingency estimation proved ineffective and highly inaccurate, experts in the industry should consider a flexible alternative approach in contingency estimation to improve the accuracy of the contingency amount.

And Performance

Industrialized construction (IC) as a promising construction mode has been increasingly adopted in China due to its advantages of enhancing productivity and reducing the labor intensiveness in the construction industry. An objective and systematic evaluation of the IC mode is essential by clarifying the current weak areas in application and improving project performance. The meager existing studies have considered evaluating the IC maturity of prefabricated construction projects from the perspective of project governance. This study proposed an industrialized construction maturity model (ICMM) involving organizational enablers by employing the framework of the well-established European Foundation for Quality Management (EFQM) excellence model. The evaluation indicator system consisting of two parts (i.e., “enablers” and “results”) were abstracted by a literature review and expert interviews. The analytic hierarchy process (AHP) approach was used to weight the indicators. The maturity of IC projects was rated as four levels (i.e., initial, upgraded, integrated, and optimal levels). The proposed ICMM was validated by conducting a multi-case study, four typical building projects that adopted prefabricated construction techniques in Shanghai were selected and evaluated by the proposed ICMM. Results showed that the ICMM can objectively and comprehensively realize the status quo of IC projects and help managers to identify weak areas of the current IC projects and performance improvement paths from the perspective of project governance. The ICMM was also evaluated to demonstrate its applicability and reliability through expert interviews.

Delphi Analysis

The authors have studied the construction-related public procurement environment in the United Kingdom to identify and analyze potential improvement strategies that may be applied in Spain. The paper comprises a comparative analysis of the environments in both countries. It focuses on recent programs to enhance the efficiency of the British administration, and includes suggestions for improving those programs and the main keys to their success. A Delphi analysis was carried out in Spain to assess, in qualitative terms, how efficiently and easily those strategies could be implemented there. The results indicate that, if implemented, many of those potential strategies would pose significant difficulties in the short and medium term. Therefore, the reasons for those feasibility problems are summarized. In any case, specific strategies used in the UK environment, explained here, could be useful for Spain and other countries with similar characteristics.
