Lean Construction Ireland Annual Book of Cases 2021 87 enablers to achieve a collective OSM goal, and taking an integrated project delivery (IPD) and early engagement approach. The early engagement of the design and construction partners provides benefits in terms of close collaboration as early as the BOD stage.This collaborative approach ensures that the design under development is based on sound construction methodology and that time is allocated to consider, identify, and advise on the best construction route based on the developing design,price, and quality. When early engagement, and ideally an IPD structure, are implemented, the project and team approach towards OSM will directly influence the development of potential project gains and Lean efficiency per Figure 2. Taking such an approach to early engagement, Jones Engineering was enabled to engage with all of the project stakeholders, design teams, and vendors.This case study details the M&E systems, capital plant, and supporting infrastructure that we were able to maximise via theOSM approach and benefit the project gains – a key objective to achieve from the outset. Figure 2. Early Collaboration & Capabilities Containerised Generator Sets (Location: Northern Holland; Project: Confidential Data Centre.) During the development of the containerised generators, early engagement enabled us to successfully and fully detail and manufacture the following elements of a contemporary generator set up, which are typically site stick built: • Cable entry box installed with cable gland plates installed and pre-drilled ready for cable termination. • All FLS services within the generator container installed and FAT tested through early coordination between the Fire Alarm Contractor and Generator Manufacturer. • BMS interfaces and network switches installed and configured. External Sprinkler &Water Meter Buildings (Location: Northern Holland; Project: Confidential Data Centre.) During the development of the external sprinkler buildings and water meter buildings, early engagement enables us to successfully fully detail and manufacture the following M&E systems: • Internal containment and supports for M&E services completed and QAQC checked. • Internal LV & ELV standalone systems installed and factory tested to L3 and QAQC vetted. • FLS systems installed and tested. • All mechanical pipework and pump work installed and factory tested. • External cable entry points installed with cable seals prior to site delivery. • All ELV wiring and BMS monitoring points installed, tested, and configured prior to site delivery. • Drainage lines pre-installed. Main Primary LV & MV PrimaryTrestles (Location: Northern Holland; Project: Confidential Data Centre.) During the early stage 3 & 4 development, early engagement with the steel manufacturer enabled Jones Engineering to install all of its containment into the primary steel infrastructure to be delivered in 13 meter sections.The benefits of using this approach were: • Higher quality of installation of the containment modules doing high-level work at low level in the steel manufacturing facility. • All MV and ELV primary containment installation time greatly reduced. • Mechanical supports in place ready for pipework installation and cladding. • H&S risks limiting working at height durations. • Drastic improvements on programme installation time. • Reduced labour costs as a factory assembly attitude was adopted in the steel manufacturing facility, and as the containment install became part of the precision process. • All earthing and bonding completed and QAQC checked. • Enabled cable pulling to be mitigated and starting earlier on the programme. • Reduction in access plant hire. Figure 3. Off-Site Manufactured Primary Steel Gantry with M&E Services CHAC – Cold & Hot Aisle Supporting Structure Modules (Location: Northern Holland; Project: Confidential Data Centre.) Once the end-user requirements were known for the data hall white space, the team was collectively and successfully able to develop M&E modules in 13 meter sections complete with systems preinstalled.The key element to achieving this OSM element is taking a nuts and bolts approach with confidence in the stage 4 design to enable a design freeze, whilst meeting all of the client/end-user requirements: • Lighting, emergency lighting, lighting controls, and fittings only. • All LV & ELV containment systems. • FireAlarm/Vesda. • Sprinkler system hangers and supports. • Distribution boards and headers localised to primary routes.
