Faster and more efficient Retrospective Digital Construction was used to develop an operational 3D FM model containing all the assets in the hospital that require servicing and maintenance. The data contained within the model is easily accessible using BIM360Field on an iPad, putting FM information at the users’ fingertips and cutting the time taken to undertake tasks. In total over 4,000 assets have been recorded, improving the accuracy of data and increasing the speed of the information transfer to the technician onsite or to the client. This has resulted in a 45% improvement in the speed of reactive jobs and a 54% improvement in the completion of PPM tasks per month. Using our hospital asset model, we were able to quickly locate and provide information on all of the hospital’s smoke and fire dampers, during a recent fire inspection. In addition, we have also used the model to carry out regular checks to ensure that water is being cooled to below 40oC at all taps. Each valve is tagged with a QR code and when this is scanned by a technician using his mobile device, they receive the latest information on that unit, including the date of the last inspection, issues identified, and when the next check is due. Once a new check is undertaken, data is updated automatically. Recently, we have added additional data to the model to meet the requirements of the NHS Trust. This has included the creation of essential electrical distribution drawings, which highlight electrical cupboards and the areas they serve, making it easier to carry out electrical work. Digitising maintenance procedures BAM has digitised the annual condition survey process at Wharfedale. In previous years the process was very onerous and involved using multiple excel sheets that were filled in manually by FM, without any knowledge of historic work. However, we have now put this process onto iPad and linked it to the model using BIM360Field. This allows users to complete checklists quickly and efficiently, view previous checklists and see what work has previously been carried out. To make the process even faster, we have installed barcodes in each room, which when scanned with the iPad take the user straight to the relevant room’s condition survey and data. As a result, our FM team are now able to carry out 60 room surveys in 2 hours, which is 33% quicker than the manual system. More effective work planning Building on our work to digitise the condition survey process, BAM has now visualised the survey results by creating hospital floor layouts that show the condition of each room. These allow BAM and the NHS Trust to see at a glance what work needs to be undertaken over a five year period and schedule these activities so that they cause minimum disruption to the hospital’s daily operations. Currently, the layouts are paper based but we are working to take this information and place it within the Digital Construction model so that the client will be able to have all the information they need at their fingertips whilst having the confidence that what they are seeing is the latest version. BAM PPP is also using the layouts in their discussions with their funders, who need to see work plans before they will release funds. The diagrams give the team a visual tool, which is quick to explain and easy to understand, helping them to secure the money they need. "The condition survey drawings linking back into the Digital Construction model are excellent and definitively represent the way forward. As a visual aid these are far more valuable to clients and the banks allowing them to easily see the high-priority (and low-priority) areas and understand that our lifecycle replacement choices are based on sound evidence and a forward-looking plan of works." Richard Oxley, BAM PPP Saving energy and money The BAM FM team are continually looking for ways to keep the building’s energy consumption at a minimum, while maintaining a safe and clean environment for patients and staff. We have helped the hospital to cut electricity usage in its operating theatres by 28% by shutting down the heating, ventilation and air conditioning (HVAC) system when the theatres are not in use. Sensors were fitted to reduce ventilation by 50% when the theatre was unoccupied for one hour and shut down completely at night and over the weekends. A quick restart sequence was programmed into the Building Management System to switch on the ventilation in case of an emergency. These changes have resulted in annual electricity savings of more than 13,600 kWh and over six tons of CO2 emissions.
