- Description: In any mega construction project, quality survey managers play a vital role in judging quality of work done by different contractors and sub-contractors. Usually a quality survey manager uses a hard copy form to records the survey information and for reporting to the client. Typically, this entire process takes a week’s time or even more, there is no workflow in place for recording information and analyzing trends in irregularity by the quality managers. The requirement to capture and report quality survey observations in real time evoked a need to research on mechanism for recording the observations using smart phone and existing GIS infrastructure without any development on smart phone and mobile devices. An integrated solution using an editable ArcGIS Server feature service and ArcGIS online web maps was developed in order to perform the quality survey. The paper describes the mobile GIS solution for construction projects. The solution allows recording observations in a real time environment through a user-friendly interface and workflow driven process. It also allows users to capture the picture and attach it to an editable feature service. The client can view this information in real time using ArcGIS online or in the enterprise geodatabase. The use of the Esri online ensures restrictions on accessibility of the content and takes advantage over other application because no programming or development is required. In addition, the information is stored in Oracle database and used for analysis in future, based on the changing reporting requirements. The developed solution saved on time, money and is easy to use and deploy.

- Description: M. Ing. , Iteration and rework are inevitable within the concurrent nature of complex modern day engineering projects. Effective communication and process coordination, as well as minimisation of these iterations and rework cycles are major contributors to the successful completion of projects. The majority of project management techniques being used does not account for cyclic flow of information which result in project schedules being developed without incorporating the iterative nature of designs. However, making use of the Design Structure Matrix technique will facilitate in illustrating and modelling the various interactions between engineering disciplines, and when incorporated in schedule development will result in more accurate lead time forecasts and less schedule overruns when executing projects.
