20 This chapter describes the degree to which airports, their consultants, and the FAA are applying state of the science technologies and SOA practices when collecting, storing, or using utilities information. In general, there is a significant gap between what airports are doing and how the SOT and SOA practices can assist in collecting, storing, and applying information on subsurface utilities.

21 change orders, the likelihood of costly utility breaks, and safety risks all go up. Many of the airports interviewed rely exclusively on design and construction project managers to implement SUE-related policies and procedures as they see fit.

22 • Electronic Document Research -- At a moderate but growing number of large and medium airports, record drawings have been entered into a document management system that enables electronic search and retrieval. These systems range from custom software developed by consultants to meet an airport's specific needs to commercially available off-the-shelf (COTS)

23 Although this is better than not capturing those marks, it is important to note that this does not lead to QLB information. ASCE 38 is currently under revision to clarify this point.

24 In most cases, airports have CADD standards that describe how the data in the CADD drawings are to be delineated on separate layers, the symbology that is to be applied, and the cover sheets and title blocks to be used. Few specify file naming, title, or page numbering conventions.

25 for utilities and communications, and is eventually slated to become a mandate for any projects that apply federal funds to the development of geospatial data, which will include most airports, few airports currently know it exists. A key challenge airports face with regard to metadata that describe utilities data is the need to describe subsets of data (i.e., specific groups of features)

26 • Facilities Maintenance -- Often preventative maintenance and work order requests are associated with utilities. When work orders are issued, it is often difficult to accurately identify the specific asset that requires attention, given the variety of verbal or written descriptions that are used to identify its location.

27 ports have general data usage guidelines that must be accepted and signed. Some airports have defined Sensitive Security Information to include utilities infrastructure that directly support security activities such as closed circuit television cameras.
