58 L EAN C ONSTRUCTION I RELAND A NNUAL B OOK OF C ASES 2018 recent construction projects where PM Group has effectively utilised graphical means as a supplemental measure to more effectively communicate schedule information. Project Demonstration 1- Civils Works On a large Bio-Pharma design and construction project, graphical representation of the civils schedule was effectively used as a key communication tool from pre-planning and constructability reviews through to site whiteboard meetings. It was used as an effective tool to on-board the CM team and Contractor supervisors and to visually communicate the planned sequence of install to both construction teams and designers. Figure 2 indicates graphically the civils installation sequence up to ground floor slab; and Figure 3 represents the superstructure build involving multiple contractors with overlapped schedules. These graphical representations of the civils schedule were found to be highly effective communication tools and extensively used at pre-planning/constructability stage, through tender stage, and into regular s i te planning, coordination, and whiteboard meetings. These were developed at an early stage during pre-planning and further developed as the project progressed into execution and site delivery. Figure 2.

Project Demonstration 2 – Existing Roof Steel Reinforcement This case study examines the scenario of two steelwork contractors working simultaneously on the same structure with an aggressively overlapped schedule. The scale of the project and the tight programme dictated the need for two separate steelwork contractors to deliver the fabrication and installation metrics required. As a result, particularly careful and detailed planning and coordination of the install was required to maximise productivity and safety in a tight, shared working space in an existing building. A significant and effective tool in achieving this was the use of graphical representation by schedule “storyboard” which provided: • Clear schedule communication which was essential for planning, coordination, reporting, and mobilisation of follow-on trades. • Direct correlation of schedule to actual site layout/specific area, for example, the schedule requi rements were superimposed onto the steel portal frame grid. • Visibility of the areas that other contractors were working in at the same time, which further enhanced coordination and safe working. Figure 4 demonstrates how the works to the steel portal frame were represented graphically in a manner that is much clearer, communicative, and more user friendly than the traditional Gantt chart.

Project Demonstration 3 – Cleanroom Construction and M&E Fit-out On a fast-track Pharma project involving mul t iple contractors and schedule interdependencies, graphical representation of schedule was effectively used to simply communicate and plan the complex sequence of cleanroom completions, equipment move-in, and Mechanical, Electrical and Instrumentation completions.

Project Demonstration 4 – Turnover Planning The turnover process on a large-scale BioPharma construction project was enhanced by the use of graphical schedule tools (Figure 6) to clearly communicate key system turnover dates and to identify simply the precursors. This information was presented at the daily turnover meeting as a s impl i f ied communicat ion tool for system owners , supervisors, and turnover personnel to manage the sequential completion of systems within clearly defined timeframes.
