capacity in the buildings power system to allow for the possible intensification of the buildings use. On a room level, electro-technical requirements may concern the provision of power outlets (e.g. asking for a minimum of four power sockets for every workstation, within easy reach for users) and the availability of data connections (e.g. asking for wireless access points in combination with data sockets for workstations). It can also be relevant to indicate which rooms need a guaranteed uninterrupted power supply or emergency power systems (e.g. server rooms, operation rooms, crisis rooms).Fittings, furniture and equipment (FF&E)The abbreviation ff&e stands for fittings, furniture and equipment, which are all elements that that can be fairly easily moved around or disconnected from the building. Think here of furniture, bathroom fittings, wayfinding signage and catering equipment. Requirements for these items usually concern details that only need to be addressed at a late stage in the design process and at the moment of purchasing. Nevertheless, they can be of crucial importance. Take the simple example of the height of the coat hook in a kindergarten: if hooks are placed too high, children cannot hang their own clothing, which will result in extra work for staff. In a hospital, a good example of a critical ff&e element concerns alcohol-gel dispensers, which should be provided throughout the building. It is a detail that has little impact on the overall design of the building, but is of great relevance to the hospitals efforts regarding infection control.Norms and standardsFor many of the topics mentioned above, there are regulations and standards available. Some of these, such as health and safety legislation and local building codes, are mandatory. These do not need to be incorporated into the brief because the design team can be expected to be familiar with them and it be will their responsibility to make sure that the building is compliant. Just referring to these standards (the building design must comply with .) is usually sufficient. There are also optional, non-statutory guidelines and it is up to the client to decide whether they apply to the project or not. There are many guidelines available on the topic of accessibility, for example. The client should decide which guidelines they want to follow and whether the entire guideline should be applied to the project or only parts of it. In the latter case, it is best to incorporate these requirements explicitly into the brief. Room data sheetsTo maintain an overview of the many detailed requirements that may apply at room level, the technical brief is often accompanied by room data sheets. These are spreadsheet-like overviews that show all the relevant requirements for every individual type of room. The requirements may concern both functional and spatial issues (as defined in the functional brief) and the requirements from the technical brief (indoor climate, finishes, fixtures and fittings, and mechanical and electrical services). Furthermore, room sheets are likely to include a numbering system for the different rooms (e.g. patient room 12.01.01) that allow the design team and the client to identify and integrate the requested rooms into the design teams design models (see also page 137 in Briefing and bim). 47
