services
My areas of expertise in survey engineering include but are not limited to the following services. Please contact us if your construction or engineering project needs assistance on any survey related assignments. We will find a solution that meets your requirements and we can help with the computation, processing and analysis of your survey data.
Tunnel Surveying:
Consultation in reference to tunnel surveys is available at any step of a tunneling project based on my expertise and experience on the subject.
Gyroscopic Orientation Surveys:
Gyroscopic orientation surveys are essential to improve the accuracy of most tunnel projects. Through the addition of measured azimuths to the tunnel traverse, the effects of error propagation on traverse measurements into the tunnel are minimized. Furthermore, gyroscopic surveys aid in the detection and elimination of systematic errors in the survey data providing an important check to confirm the reliability of the tunnel survey control network.
Shaft Plumbing SURVEYS:
Methodology reporting and consultation for the survey of shaft plumbing projects that are based on the shafts dimensions, depth or height and survey tolerances.
Network Pre-Analysis:
The investigation of different network geometries, types and models of equipment and procedures to determine the point accuracies that are achievable with the layout before any actual survey work has begun.
Survey Network Adjustments:
Rigorous adjustment of survey networks with the use of redundancies and weighting of measurements to produce the most accurate network results.
Deformation Monitoring:
Comparison and statistical analysis of two or more epochs of the same survey network to diagnose if points have shifted and to what level of certainty.
Map Projections:
The determination of distortions and application of corrections to the project coordinate system and the correction of measurements that affect the accuracy of the mapping solution.
Custom Survey Forms & Spreadsheets:
Design and programming of custom forms and spreadsheets including formulas and VBA-macros.
Survey Data Analysis & Statistics:
Computation, drafting and analysis of survey data as well as the statistical analysis of survey data.
Quality Assurance/Quality Control Processing & Reporting:
Solutions for the Quality Assurance of survey projects. This includes equipment calibration procedures, estimation of error propagation in regard to survey measurements and survey procedure guidelines to assure that targets are met. I also process and check survey data to confirm the Quality Control of your survey field work.
Survey Methodology Reporting:
Reports on the methodology and procedural aspects of surveying tasks within the construction or civil engineering project.
