Construction project supply chains and their use of ICT

Abstract: This paper describes the first stage in a much larger project, funded by the Co-operative Research Centre for Construction Innovation in Australia investigating the application of supply chain concepts in the context of the construction project to develop a model of supply chain interaction that is appropriate for investigating ICT adoption both within a single construction project and across the sector. It models the influences described in previous literature relating to ICT-related supply chain participant performance and further proposes an on-line, modified Delphi methodology to facilitate the asynchronous participation of an international panel of experts in the validation of the model. It concludes by reporting the findings from the study and directions for further research.

Information System for Dynamic Updating of the Planning Work

Abstract: For the sound development of the routine activities in civil construction companies, planning and effective control are necessary for the successful execution of the construction site of enterprises. Therefore, a communication scheme is needed between the office and the construction site staffs, in order to make information available and let it be exchanged in an accurate way by the teams involved in the enterprise. This will allow to make decisions and define processes in proper timing. Considering the education differences between the workers in the construction site and also the informality of the trainings, communication must be not only organized and structured, but, also, affordable. Through the technique of the balance line, a graphic technique that links space and time to organize tasks, and using information technology, this paper proposes the development of an information system capable of the real-time updating of the planning considering what just happened on the construction site. This will promote an easier interaction between the user of the system on the construction site and the users in the planning and management office. Nowadays, this task is accomplished manually, causing information to be always lagged regarding the situation of the work, due to the time required to acquire and process information. Using currently available technologies in order to obtain a user-friendly, interactive control panel in the construction site to transmit information in real time, a panel with multi touch screen technology was proposed, which allows to access information easily, by touching the panel with the fingers. In order to adopt this technology, the proposal defines the structure of an information system for management and control of construction site information, including the documentation of projects, teams and workers data, schedules, updates and related information.

Estimating Constructability Review Benefits for Highway Projects

Abstract: Constructability review is a process used in the design phase of a project in order to interject construction knowledge and address potential issues prior to construction. This typically occurs with a team or panel of constructability reviewers. Current staffing and budgetary constraints have resulted in state transportation agencies being very careful about disturbing the existing project development process with practices that seemingly lie outside the main process, such as constructability review. An issue that constructability reviews face is the lack of any documented savings. Over the past decade, the Kentucky Transportation Cabinet has streamlined the constructability review process by relying on a smaller team or single reviewer per project and recently taken on an effort to estimate monetary benefits from such reviews. This paper discusses the evaluation of constructability reviews at the project level by comparing change order percentages on projects reviewed versus those not being reviewed. This approach showed a clear indication that there are monetary savings associated with constructability reviews resulting in a conservative savings estimate of 1.25 percent of the project cost without including the additional inherent savings in time, lessons learned or other aspects not readily quantifiable. This evidence presents that a streamlined constructability review process and team can still provide savings to a project. A regression model was also developed in this work to estimate the potential monetary gains from the constructability review comments but additional analysis is needed to improve accuracy. There is potential that this model could be used to further streamline the process by identifying and focusing on projects where constructability review savings could be maximized.
