Lean Construction Ireland Annual Book of Cases 2021 13 MaceTechnology (Ireland) has been established in Ireland for over 10 years and has constructed two of Ireland’s largest and most prestigious projects, namely Dublin AirportTerminal 2 and Project CLN, a hyper-scale data centre campus in Clonee,Co.Meath.Mace Ireland operates not only as a general contractor here in Ireland, but also provides professional construction services such as cost management and programme management for blue-chip clients such as Microsoft, IrishWater, Eirgrid, and Facebook. This study was carried out on a hyper-scale data centre that entailed both design and build and design-bid-build phases. Preparation and approval of design documentation is a key factor for managing an efficient production control system. Construction projects are complex projects that involve multi-disciplined stakeholders with the preparation and coordination of design activities in line with strategic milestones. Design is linked to construction activities and then through to inspection and quality control. Design teams and construction teams need to collaborate to create and verify design documentation before procurement and site installation and inspection.Team fragmentation has been identified as a barrier for efficient design management, and design teams, contractor supply teams, and vender supply chain are dispersed. The Last Planner® System (LPS) was identified as a possible solution to managing contractor drawing and technical submission improvements. In parallel with Lean and BIM management, design deliverable dates were identified in advance of programmed construction dates. Shop drawings and technical submittals were prepared for review by the design team.This was managed in line with the construction programme which allowed planned works to proceed safely and in a timely manner. Design Last Planner System Construction is a series of actions undertaken by construction companies which produce or alter buildings and infrastructure. Individual construction companies become competent at one or more of the actions over many years, and they apply their specialised skills and knowledge on construction projects.The design and construction of buildings and infrastructure are undertaken by specialist design and construction professionals, and supported by an integrated network of suppliers and specialist contractors. Integrating project teams to work collaboratively has increased productivity in construction.The lack of approved design documentation had been noted as a significant factor for missed assignments in the construction last planner process. Improved coordination between trade contractors, main contractor, and design teams was required to improve the delivery of approved design information in line with planned construction activities.To integrate design and construction activities, a design coordination and last planner meeting was scheduled weekly.The purpose of that meeting was to improve communication between construction and design teams.The meeting was structured to provide a coordinated look-ahead document preparation schedule.This was managed in line with the construction programme for the timely preparation of documents to ensure that there was an uninterrupted workflow for construction activities.The vision for all stakeholders is to deliver the highest quality project with all documentation complete and defectfree at practical completion.To achieve this, a collaborative approach to design, construction, and inspection was required. Design and Quality At the interface between design and construction, the following questions accentuate: • Has the design of the elements been completed? • Have the necessary technical submissions and benchmarks been approved? Work needs to be considered in greater detail as the make-ready process focusses on matching the available resources for work with the present realities on the construction site to ensure production can proceed at an optimum level. Information flows connect activities to design and quality to facilitate the make-ready process. Only when this is agreed can tasks be considered for execution in weekly work plans. The importance of information management, and the ability to share information between project stakeholders to ensure that the project requirements are met, provides a robust platform for managing task allocations and sequencing. The value-added data is one that supports the craft worker by ensuring that the planned works proceed uninterrupted and that any variance from the plan is forecast and mitigated to manage resource utilisation.This relationship between information and material flow suggests that design last planner improves the overall production Company Overview MACE macegroup.com Overview & Background to the Lean Initiative Lean Initiative Undertaken – Lean Thinking, Tools, Techniques Daire Nolan Author Ciaran Fennell Author Case 3 Kevin McHugh Author
