Solutions
for Facilities Data Management
Energy and
Telecommunications Services
Since
1979 Sewall has provided services in GIS development and maintenance
to energy and telecommunications companies throughout the country.
With experience in utility data conversion, database design, and
software development, Sewall has assisted clients through every
phase of an GIS project, from needs assessment and strategic planning
to system implementation and user training. During this time, Sewall
has facilitated data cost-sharing arrangements between major utilities
and local governments.
SYSTEMS
CONSULTING
Sewall analysts
have assisted utilities in the planning and design of enterprise
systems, providing such services as workflow and requirements analysis,
business case development, systems integration consulting, and database
design. Sewall also performs data QA/QC as a separate service to
support clients with conversion activities.
DATA
CONVERSION AND SYSTEMS INTEGRATION
Depending on
client requirements, Sewall collects and converts existing landbase
and facilities data from hardcopy source documents, migrates digital
data from one system to another, or acquires new data with aerial
and ground surveys. The complexity of utility data conversion demands
highly developed skills in problem identification and resolution.
Sewall's GIS analysts are experienced at integrating maps at different
scales or coordinate systems and in reconciling landbase and facility
data contradictions to ensure integrity and consistency. With expertise
in various industry-standard software environments, Sewall analysts
deliver digital files compatible with existing databases or designs
custom models with full connectivity. Sewall personnel are ready
to integrate and test all system components and provide individualized
user training.
ENTERPRISE
DATA MAINTENANCE
In an open market,
more utilities are choosing to outsource non-core business processes
to provide superior service to their clients. Yet current data demands
require maintaining technical staff, training, technology, and support
at increasing expense. To streamline corporate operations, reduce
data maintenance costs, and increase productivity, Sewall performs
work order conversion and posting services. With remote access,
Sewall analysts speed posting of changes to enterprise systems,
providing utilities with reliable, accurate, and current data.
APPLICATION
DEVELOPMENT
To meet the
needs of gas pipeline operators, Sewall has developed several configurable
software systems, including component-based tools that generate
alignment sheets and perform MAOP calculations, class location and
risk analysis, and HCA calculations. These components use ODBC to
maximize database connectivity and COM to allow easy, cost-effective
customization.
