LandTech employs the latest surveying technology, utilizing 3D High Definition Survey Laser Scanning for documentation of existing infrastructure & buildings. Laser scanning with capture rates of up to 1 million data points per second allows us to collect an incredible amount of information in a very short time. All data points are captured in three dimensions resulting in very accurate documentation of the existing conditions. Data can be captured at substantial distances without needing to physically access the item being documented, allowing for operation out of harms way.
LandTech Consultants combines experience with technology to employ the right equipment for each application to provide the most complete & accurate data for a successful project. Often it isn’t enough to simply laser scan a project for documentation. LandTech capitalizes on over 25 years in the surveying industry, supplementing laser scanning activities with robotic total stations and the latest GPS equipment. Utilizing robotics, LandTech has the expertise to locate scanning targets to assure a tight survey grade control system for tying multiple scans together. Scanning data can then be tied to your choice of co-ordinate system utilizing GPS.
Structural elements and bridges can be documented quickly and accurately without the need to place personnel in dangerous situations.
Dimension, elevation and location of bridge seats can be located quickly. Bolting patterns on gusset plates three stories high can be identified and measured safely from the ground. Bridges over highways and railroads can be documented with no impact to transportation.
Intersections, roadways and highways can all be scanned with minimal impact to traffic flow, increasing safety and reducing the need for traffic details.
Edge of pavement, top and bottom of curb, paint lines, catch basins and manholes, signage and street lights are quickly obtained. Additionally, height of overhead utility lines, traffic lights and tree canopy are all captured in the scan, accurately and quickly. Retaining walls, dams, sluiceways, drainage facilities and the like can all be documented with incredible precision at safe locations and much faster than conventional methods.
In addition to basic building dimensions, 3D laser scanning quickly and accurately documents building facades, window and door openings, stairwells, moldings, penetrations and decorative scrollwork and details. Elevator shafts, mechanical rooms and interior MEP/FP is quickly located with precision. Laser scanning can even be completed above suspended ceilings.
Utilizing conventional survey techniques to tie multi-floor interior and exterior laser scan data sets together, an accurate and detailed existing conditions Building Information Model can be quickly assembled from the results of a 3D laser scan.
Scanning of large materials piles can be completed quickly and safely without the need to place personnel on instable slopes. Once scans are completed, material volumes can be calculated quickly and with much greater precision than when utilizing conventional techniques.
When is having an accurate material volume important?
- Construction activities utilizing on site materials
- Stockpiled product volumes for inventory and sales
- Salt storage carry-over for municipalities
We’ve even scanned stone quarries to determine the amount of material removed.
Utility facilities generally incorporate inherent danger. Documenting locations can be difficult and dangerous for numerous reasons. 3D laser scanning removes the danger allowing documentation to occur at safe distances.
Cell, radio and electrical transmission towers can be accurately documented from the ground to determine structural condition, space for expansion, proper orientation and overall capacity among other uses.
Electrical utilities utilize scanning for documentation of sub-stations from outside protective fencing, obtaining height of transmission and distribution lines, inspecting condition of transmission towers and insulators, safely and accurately.
Renovation and archiving of historical structures is an ideal application for 3D laser scanning. The amount of detail captured by laser scanning allows for the fabrication of replacement components for damaged structures as well as for additions that are designed to incorporate the integrity of the existing structure.
Complete scans of historical structures are often completed to preserve an accurate archive. These archived scans can later be accessed if needed to be utilized in providing the documentation necessary to repair or replace structures that may be lost or damaged due to disrepair, fire or natural disaster.
Manufacturing facilities often retool for new products. As a result, assembly lines are reconstructed to accommodate new processes.
Conducting a 3D laser scan of the existing facility provides the information needed to develop accurate plans and models of the existing structure with complete structural, MEP/FP and process equipment. With this information in hand, the design of a new assembly procedure can be completed with ease. Even the individual machinery components can be scanned and recreated in a virtual world so that a complete 3D model of the facility and process line can be assembled prior to actual construction.
Topographic contouring obtained through laser scanning can quickly and accurately create a 3D model of existing terrain conditions. The ability to have this information is essential in computing volume calculations for earth movement.
High definition laser scanning survey data uses:
- Assessing grades for accurate drainage
- Verifying as-built data to assure proper construction
- High accuracy grading such as golf courses and playing fields
The ability to acquire, document and model information to extremely accurate levels in a short amount of time results in faster turnaround, lower costs, and better construction.
