3D CONSTRUCTION SURVEYING
3D CONSTRUCTION SURVEYING
As a complete replacement for traditional surveying methods, which yield hard-to-verify 2D measurements, E2CS's 3D construction surveying technology with laser scanners offers a fundamentally new approach. It is visual, accurate, and reliable, delivering a complete 3D model fully reconstructed from point cloud data.
With a team of engineers possessing extensive hands-on experience and utilizing professional 3D data processing software, E2CS provides 3D surveying services across the following areas:
3D CONSTRUCTION SURVEYING
This service precisely captures the actual as-built dimensions of a structure, serving critical needs for archiving, inventory management, renovation, or expansion. E2CS's 3D surveys also accurately identify the coordinates of tie-in points to facilitate the planning of new construction or modifications.
Applications:
– Complex Architectural Features: Arches, staircases, railings, and facades.
– Industrial Plants: Chemical processing, oil & gas refineries, water treatment, and pre-engineered steel buildings.
– Transportation Infrastructure: Steel bridges, tunnel systems, and roadways.
3D TOPOGRAPHIC SURVEYS
Utilizing Time-of-Flight (T.O.F) laser scanning technology with an accuracy of 3.5mm + ppm and a maximum range of up to 500m, our 3D topographic surveys can precisely capture the dimensional data of any terrain.
Applications:
– Topographic surveys for landscape design.
– Creation of digital models: DSM, DTM, TIN, and DEM, with the ability to establish stations on national coordinate and elevation benchmarks.
– Calculation of cut-and-fill volumes and direct generation of contour maps from 3D Point Cloud data.
3D SURVEYING IN CONSTRUCTION MANAGEMENT
This solution integrates high-precision measurements tied to the project's geodetic control network with a direct comparison between the design model (BIM) and as-built site conditions to verify construction quality.
Applications:
– Documenting concealed systems (underground utilities, in-ceiling MEP) before concrete pouring or closure.
– Creating 3D as-built documentation for project turnover.
– Remote verification of construction progress, quantity take-offs, and quality control.
APPLICATION OF 3D SURVEYS IN CONSTRUCTION INSPECTIONS
With its comprehensive, high-density point cloud data that accurately reflects real-world dimensions, E2CS's 3D survey is the ideal solution for building quality inspection and structural assessment.
Applications:
– FFL/EFL Analysis: Verifies floor and wall surface tolerances.
– Detects settlement or deflection in structural elements.
– Verticality Checks: Ensures alignment of columns, walls, and vertical components.
