Primary Services
Survey Control Networks
Sophisticated control networks are established by JBA to “tie down” a property and
provide the backbone for all subsequent survey activities.
Topographic Surveys
JBA uses conventional equipment and GPS to construct topographic maps illustrating
the existing characteristics of a site, including topographic contours, natural features,
vegetation and trees, buildings, roadways, utilities, and associated elevation and
attribute data. These topographic surveys provide the basis for all subsequent project
site design and engineering.
Boundary Surveys & Records of Survey
A Boundary Survey is developed to physically locate a client’s deed on the ground. If
the property has been previously surveyed, JBA retraces the survey, finds existing
monuments (property corners) and/or replaces missing monuments, and provides a
map of the survey. If the property has not been surveyed previously, JBA establishes
property corners and prepares/files a Record of Survey with the appropriate county.
Design Surveys
Design Surveys are prepared to provide a base drawing for use by engineers and
architects. They illustrate the physical features and constraints affecting development of
a site. Design Surveys generally include boundary re-establishments, easement
locations, man-made and natural features, elevations, contours, and utility locations.
Specific items can be omitted or added as appropriate for each individual project.
Construction Surveys
JBA has extensive construction survey experience. We provide rough and finish grade
staking for all phases of construction and as-builts of completed work. We frequently
deploy teams using GPS and total stations for large-scale mass grading and detailed
concrete slabs.
Hydrographic Surveys
JBA utilizes GPS with sophisticated sonar sounding equipment to measure the bottom
of water bodies. Mining quarries that have been excavated below the water table are
also surveyed using this method.
ALTA/ACSM Surveys
The ALTA/ACSM Land Title Survey
Standards have been jointly adopted by
the American Land Title Association
(ALTA) and the American Congress on
Surveying and Mapping (ACSM). These
standards were developed as a collective
effort in order to create an accepted and
recognized legal document that presents
particular nformation in detail and
exactness for acceptance by title
insurance companies. ALTA/ACSM
Land Title Surveys are recommended for commercial transactions in which extended
coverage is required and/or where extremely detailed information is needed.
Tract & Parcel Maps
Various methods are used for the
subdivision of real property, including
Tract Maps, Parcel Maps, Parcel Map
Waivers, Lot Line Adjustments, and Gift
Deeds. JBA provides surveys to locate
existing improvements for the
preparation of these subdivisions and
associated documentation.
Mining Surveys
Mining Surveys are used to establish the
surface locations and boundaries of mining claims. During mining or tunneling
operations, the Mining Survey helps to establish the location of underground
operations horizontally and vertically, lay out shaft connections, and guide tunneling.
This is three-dimensional traversing, not essentially different from surface surveying.
Mine Limit Monuments (MLMs)
|
|
JBA has developed a monumentation process to assist plant managers in controlling
the mining limits of their respective plant sites:
1. The plant boundary is established in the field and drawn in AutoCAD. Once the
boundary is completed, the project mining limit is calculated and inserted into the
AutoCAD drawing. Major angle points and specific instances along the curves
and straight lines are then monumented.
2. Temporary points are set and “tied out”, and the final monuments are set.
3. Once the concrete has dried, the survey crew will return and locate final positions.
These positions are read electronically into a custom database that provides the
client with a detailed report on their particular mining operation.
Stockpile Quantities

Stockpile quantities in the mining industry equate to significant bottom-line dollars. JBA relies on proven methods for obtaining necessary field measurements and
building complicated detained digital terrain models (DTMs) to assist in quantifying
and managing stockpiles.
Aerial Surveys
A significant amount of topographic
mapping is done by means of aerial
photogrammetry, which uses stereoscopic pairs of photographs taken
from aircraft and, more recently, from
artificial earth satellites. Horizontal and
vertical ground surveys must appear in
the photographs. These photos are then
reconstituted into stereo models for
drafting true-scale maps. Precise
cameras are required, and precision-mapping equipment is used to depict natural and artificial objects in true position and to
show true elevations for all points in the mapped area.
JBA incorporates sophisticated network designs to ensure accurate aerial target
positions for aerial survey projects. |
