Surveying

BIA provides a full range of surveying services and has coordinated and integrated boundary and ground control surveys and aerial photogrammetric topographic surveys for many large-scale projects. Our base plans are used by architects, developers, and municipalities, as well as commercial, industrial, and institutional clients for planning, site developments, and subdivisions. We can also field up to seven survey crews simultaneously.

Boundary Surveys (projects)

This type of survey is made to establish or re-establish the outline of a parcel and to locate or set boundary monuments, as required for a variety of legal or development purposes. BIA's surveyors "collect" enough data and record information to allow them to determine the point of beginning, define each course of the tract in sequence, and end back at the beginning. The plan produced from the survey includes information on the lot's dimensions and acreage.

Topographic Survey (projects)

This survey shows existing natural and manmade features as well as elevations and contours. A Topographic Survey Plan, or Existing Features Plan, is typically used as a base plan for many kinds of development projects. The scope of projects BIA has provided topographic surveys for range from one acre to several hundred.

ALTA (projects)

Title insurance companies typically require this kind of standardized survey for commercial properties. The standards were developed by the American Land Title Association (ALTA) and the American Congress on Surveying and Mapping (ACSM).

Construction (projects)

BIA survey crews use information on site plans to set reference stakes that show contractors the proposed location of site improvements. Various kinds of construction stakeout projects include buildings, utilities, roads, parking lots, sidewalks, and grading. BIA crews can perform rough or precise layouts — and can be on site whenever the contractor requires.

Utility (projects)

Accurate utility surveys are essential for engineering design. These surveys locate the visible portions of overhead and underground utilities and may include the marking of underground lines by BIA or an underground utility location subcontractor. Plans are prepared from this data as well as from record utility drawings.

GPS (projects)

The Global Positioning System (GPS) is a global-navigation system formed from a constellation of 24 satellites and their ground stations. On large projects, GPS technology gives surveyors the tools for an even higher degree of accuracy than traditional survey methods, while reducing the time and personnel required. The positioning accuracy of GPS can be as close as plus or minus one (1) centimeter, depending upon the equipment and methods used.
