Naval Station Ingleside - ALTA Survey and GIS

Ingleside, Texas

Scope of Work:As part of the Department of Defense’s Base Realignment and Closure, Naval Station Ingleside, Texas was closed in April of 2010. Located on the north shore of Corpus Christi Bay, the site is strategically located to serve as a deep-water port for offshore drilling services.

Principal Elements and Special Features:Frontier was contracted to complete an ALTA survey of the 800-acre facility. Frontier mined existing Naval Base GIS data the U.S. Navy collected prior to closure. Data was uploaded to mobile GIS devices and used to assist field crews in completing a detailed, comprehensive boundary survey. Field teams rapidly and accurately mapped and attributed the facility’s dense infrastructure including buildings, roads, and all above ground improvements. Hydrographic surveys were completed along the bulkhead that fronts the intercoastal waterway. Frontier calculated the volume of dredge material needed to deepen the site to accommodate deep-draft ships. The field information was ported to GIS databases accessed via a secure, cloud-based web portal. The database, maintained by Frontier, is used as a planning and asset management tool.

Relevance:This project illustrates our capabilities to quickly collect, aggregate, and analyze voluminous amounts of surface and sub-surface data, and make it available via secure, web-based GIS applications.

Bullard Oil Pipeline - EnCana Oil and Gas

Hill County, Texas

Scope of Work: EnCana Oil and Gas (USA) Inc. employed Frontier to survey surface tracts, hazards, utilities, proposed pipeline route, and as-built survey for the Bullard pipeline in Hill County, Texas. This project involved 10 separate surface tracts and spanned four miles in length.

Principal Elements and Special Features: Warranty Deeds with metes and bounds descriptions were obtained from the Hill County Clerk’s office and were used to create working sketches for locating the property boundaries of the various surface tracts the pipeline would cross. A centimeter level, survey-grade GPS was used in real-time Kinematic mode to locate and tie in property corners, hazards, utilities, and fences. This information was then used to resolve surface boundaries and plan a route for the proposed pipeline. The proposed pipeline was staked on the ground including permanent and temporary easements. Once information was collected in the field, construction alignments, exhibit plats, and road profile permit plats were generated in CAD. As the pipeline was being constructed, a field crew performed an as-built survey of the pipeline in order to document the pipeline’s location, elevation, heat and x-ray numbers, and depth of cover.

Relevance: This project illustrates Frontier’s ability to work in varied locations throughout the state and adhere to client specific requirements.
