A number of clients utilize the services of AB&H, A Donohue Group, for collection and compilation of information necessary to locate and document system components to facilitate keeping permanent inventory records and maintenance data. These systems also allow immediate and effective responses to emergencies under associated adverse conditions. This is done efficiently and economically by maximum utilization of interactive computerized record, drafting, and mapping programs.

As a routine matter, the firm provides detailed drawings of records as part of field engineering services to document the work performed at to ensure that sufficient information will be available for the client's record system. These records are based upon references to both physical features at the site which are easy to use but subject to change with geographical coordinates which can always be established. In addition, we can provide the necessary technical assistance and personnel time to convert existing systems based upon paper records and physical features to global positioning coordinates be unaffected by future physical changes and that can be established under adverse weather or emergency conditions such as flooding. As an adjunct, geographical information systems can be developed to facilitate the use of the data for a wide variety of operational and maintenance functions.

This is facilitated by using technology that permits accurate determination of coordinates, which can be downloaded directly into the desired computerized drafting and/or record systems.
