"In the very beginning, to get buy-in from my operators, ESD could show them how to run it, how to maintain it in the virtual world, which is fantastic," Bar- clay says. "If we had to remove a piece of pipework for routine maintenance, this would show you how that piece of kit is li‚ed, moved and operated. For my team, it meant they could visualise things before it was even built." ESD also used Synchro, a 4D visualisation tool, to aid the pro- ject. The so‚ware 'automatches' the 3D BIM model to the project schedule – thereby adding time as a fourth dimension – and provides a sequenced visualis- ation of the build process. "It allows us to run through a virtual rehearsal of the installa- tion with all the team and ven- dors and subcontractors and then tweak it to make sure it's right before we do it physically," Jones says. "We can sit down with a client and other stake- holders and run through the video, and it's just like watching TV for them. It means that, come the day the plant goes into operation, everything should run smoothly." These tools were also useful in helping the Design for Offsite build was used extensively on the project New dimensions • With ESD making extensive use of BIM including 4D visualisation tools, Scottish Water has successfully completed a £29 million project to replace Tullich Water Treatment Works near Oban By Robin Hackett W hen Scottish Water engaged ESD to start work on a new water treatment works in Argyll and Bute in late 2015, it sparked a new approach to collaboration through digital engineering. ESD, a fully integrated joint venture between Black & Veatch, Galliford Try and MWH Treatment, had been awarded a six-year non-infrastructure framework contract with the utility earlier in the year and was handed responsibility for the £29 million scheme to replace the ageing ozone plant at Tullich near Oban. "ESD provide design, con- struction, process, commission- ing – all the way through, almost from start to finish – when they work on these pro- jects," Scottish Water project manager Eddie Burns says. "They work on all aspects of delivery." Strong working relationships had already been established within the project team as the result of previous joint ventures involving the ESD contractors, and many among them were well acquainted with modern BIM tools. When preparations for Tul- lich began, they seized the chance to introduce new work- ing methods that would bring about greater levels of collabora- tion through digital technologies. "We brought a different way of thinking about project deliv- ery to Scottish Water," ESD pro- ject manager Kenny Jones says. "Our digital delivery platform was relatively new technology to Scottish Water, and it meant a new way of working – it brought an open dialogue between all the parties and a joined-up approach to getting the best out of construction activities." The plant model was built using BIM 360 Glue, a cloud- based solution that can connect the whole project team. BIM 360 Field, an add-on that enables team members to manage field data almost anywhere on the job site, was also used. "We focused on 3D visualis- ation using BIM 360 Glue, which allowed our supply chain to interface with the model and add in their specific pieces of equipment," Jones says. "We had a lot of vendors adding in. "The model was also used for visualisation with Scottish Water and brought a lot of infor- mation to the screen – it was really good for design develop- ment meetings. Some of our col- leagues within Scottish Water probably weren't as used to using construction drawings as our contractor colleagues would be. The beauty of being able to look at a 3D model is you don't necessarily need to be able to read complex 2D drawings."
