With advancements in technology, Van Harten is always adapting our role in the surveying and engineering industry to ensure that we remain current with the time.
Below are some of the more unique survey services offered at Van Harten.
GIS PARCEL MAPPING
Van Harten has been involved with some pilot GIS parcel mapping projects including a map of all benchmarks within Orangeville, burial plots at a municipal cemetery in Grand Valley and parcel mapping of Elgin County. Nobody understands datums, projections and coordinates better than surveyors, and our crews can provide the data with the highest accuracy possible.
With increased interest in clean, renewable sources of energy, Van Harten has been providing extensive survey work to assist with the development of local wind farm projects. This work includes topographic surveys, reference plans and construction layout services.
SOLAR PANEL ROOF SURVEYS
With a growing trend toward solar energy, Van Harten has carried out a number of flat roof-top topographic surveys of commercial buildings to assist with the design and layout of large grids of solar panels. This survey will locate any air conditioner units, vents or other obstructions that will affect the layout of the panels.
Van Harten is equipped to complete ALTA® Surveys in accordance with the policies and procedures of The American Land Title Association of the United States. In simple terms, an ALTA® Survey can be compared to a combined full boundary and topographic survey along with all planning data. ALTA® Surveys can be further researched at http://www.alta.org/forms/ and the standards can be downloaded here.
HIGH PRECISION SURVEYS
Occasionally we are retained for unique projects to provide extreme accurately measurements. We have measured concrete pads with millimetre contour maps, assisted with precise placement of large glass panels on a tower and measured settlement of a house foundation to the tenth of a millimeter. Our firm has the survey equipment and experience to provide these services.
Van Harten has the ability of creating 3D modeling using various field techniques (including 3D scanning) and CAD programs. This service was been provided for an existing multi-storey building that did not have architectural plans to assist with the creation of condominium plans clearly depicting three dimensional boundaries between individual units. This service was also provided for a commercial building that had been badly damaged by fire to assist the architect in the design of the necessary repairs. This service provides builders and homeowners assistance in the orientation and design of custom rural estate homes.
While traditional construction layout is still provided in the industry, some grading operations are now being carried out by machines equipped with GPS units. These GPS units are connected to a computer control systems that provide the operator with the necessary cut and fill operations. Van Harten can provide data conversion services that will take the UTM topographic survey data and engineering design into a format that the machines can read.
Rural developments within the Niagara Escarpment or other environmentally sensitive areas sometimes require a visual assessment to ensure that the integrity of the natural environment will not be impaired following construction. A Visual Assessment includes a series of pictures of the property from various vantage points along the road that show the new building as if it's already there. Using topographic data along with site photos, architectural drawings and the site plan design, the buildings are digitally modelled into the terrain to provide a visual image of the final product from various vantage points.
