The Reasons To Hire Professionals GPR Surveyors
GPR surveyors from companies like KBGPRSurveys can be a great asset when it comes to getting an accurate reading of the ground beneath your feet. They use radar technology to map out the subsurface and can provide a wealth of information about what lies beneath the surface. This makes them essential for a variety of purposes, from construction to archaeology. Here are four reasons you should consider hiring a GPR surveyor.
Examine bridges
The GPR survey cost can be very beneficial when inspecting bridges. When it comes to prioritisation for the purposes of budgeting, the method works particularly well. In addition, in contrast to the results of acoustic methods, GPR data is quantitative. Collecting data at a walking pace typically requires using a cart-based system equipped with an antenna and a controller. The radar technology is able to detect flaws in the concrete by analysing the strength of the signal that is returned from the reinforcing steel. The stronger the signal, the better the concrete. The technology can ascertain the depth of the rebar and the location of the tie bars, dowel bars, and rebar.
Utilised in order to guarantee quality
GPR surveying can also be utilised to evaluate a newly constructed bridge deck's quality assurance and quality control (QA/QC) to ascertain whether the rebar depth satisfies the necessary specifications. During the post-pour quality assurance process for the bridge deck, concrete cover measurements are typically taken to ensure that the top rebar mat is within the depth range specified in the bridge plans. Along one or more profile lines, a ground-coupled antenna is used to collect data to record the rebar reflections' arrival time. After that, the rebar depth is determined by drilling a core into one of the locations where the rebar is located. This information is then entered into the processing software, which calculates the radar wave velocity. This information is then used to calculate the rebar depths along the data-collection profile line at other points.
On sites of archaeological excavation
GPR surveyors must gather as much information as possible about the site before even beginning the scanning process. They are going to look for old maps and ensure they have access to the findings of walkover surveys that show the concentrations of archaeological features and the artefact density. GPR surveyors will most likely have some concept of what researchers anticipate the GPR will show them; this will allow them to be aware of what to look for during the survey.
As part of this information gathering, GPR surveyors will work closely with researchers, who will need to pay close attention to the landscape. They may be perched precariously on the side of a mountain that's difficult to access. Alternately, they could work in a region that is either completely devoid of vegetation or contains a substantial amount of vegetation. In spite of this, their GPR equipment must be moved in a straight line, and the antenna is mounted on the ground; consequently, a heavily vegetated site must be cleared before a GPR survey can be performed there. Basically, anything that would be challenging for a lawnmower to navigate would also present challenges for equipment used for GPR. In addition to this, surveyors need to be aware of the time period that is the focus of the investigation, the findings of the preliminary archaeological investigation, and the number of archaeological features that need to be mapped.
Find hidden crypts and vaults
GPR surveying has been used in a great number of studies to carry out surveys on historical floors in old churches. Nevertheless, GPR surveyors would first conduct an inspection of the building's technical state assessment before carrying out the survey. They intend to use GPR to find air gaps in the subfloor and historical items and artifacts buried beneath the ground, such as ruins, human remains, brick walls, and pipes. GPR is especially helpful for conducting surveys over large areas because it enables handling a large amount of data in a reasonable amount of time. This makes GPR particularly useful for conducting such surveys. In other research, the GPR method was shown to be effective in imaging concrete strengthening systems, reinforcement bars, cracks, defects in the form of air voids, delamination, and moisture, and it also showed promise in detecting delamination.
The GPR survey is widely recognised as a non-destructive method that is particularly suited for use on historical artefacts. The requirement to keep cultural heritage buildings in pristine condition for the benefit of future generations is driving increased demand for its application in these kinds of buildings. Historically significant objects that date back several centuries typically have insufficient or missing technical documentation, which results in a lack of knowledge regarding the precise structure of the object. In situations like these, conducting an inspection in situ is an efficient way to gather information. This method is frequently supplemented by numerical analyses, which provide design guidelines and recommendations for planned reconstruction, strengthening, and restoration works.
GPR surveyors can help you map out the underground infrastructure of your property before you start construction. This information is essential to prevent any damages that might be caused by digging. GPR surveyors can also help you locate pipes and cables so that you can avoid them while you are working. If something does go wrong, a GPR surveyor can help identify the issue and provide a solution
