The detailed survey will consist of two sections. The first section will be carried out by a civil engineer to establish whether the identified floor space is capable of being converted into a Physical Co-Location Facility and to produce an estimate of the work and costs involved. The second section will be carried out by Provider resource management staff to assess the capabilities of existing building facilities such as power, climate control, fire suppression (where available), fire alarms, to support the requirements of the Infrastructure Seeker for the Physical CoLocation Facility. 4.3.
