Surveying techniques are essential for different stages of a construction project. For instance, ground-penetrating radar is a utility mapping technique that determines the location and depth of utilities such as water pipes, gas pipes, electrical lines, etc.
In this blog, we will take a look at two advanced surveying techniques; 3D scanning and ground-penetrating radar survey. These procedures employ highly sophisticated technology to map different aspects of our environment. For example, GPR works on sub-surface environments, while 3D mapping captures millions of data points for a 3-dimensional image.
3D scanning is an accurate and reliable land survey method that has a wide range of applications. Engineers, surveyors, and scientists employ 3D scanning technology in mining, civil surveys, virtual designs, application development, and archeological projects.
3D scanners contain complex devices that map out cloud data points. In the device, there is a transmitter, photodetectors, GPS, Inertial Measurement Systems (IMS), and other advanced sensors. It works by sending beams of light to different data points. The 3D scanner measures the time it takes for the laser light to travel back to the photodetectors. The device can also measure the deviation in the reflected angle.
A 3D scanner does complex calculations for all the data points it captures in space. The device captures millions of points (in mere seconds) that are interpreted by dedicated software to form a spatial image of the 3-dimensional environment.
Ground-penetrating radar surveying is a non-invasive procedure for mapping sub-surface structures, objects, and utilities. A GPR device uses electromagnetic waves to determine the location and depth of objects buried beneath the earth. It sends pulses of radio waves through a transmitter and receives the reflected waves or echoes through a receiver.
You should know that different materials have different densities and electrical conduction properties that affect how the waves will be absorbed, reflected, and refracted. The GPR software uses dedicated software to develop images of the sub-surface structure.
GPR survey is essential to utility mapping or location services. The device is capable of identifying or recognizing metal, plastic, concrete, PVC, and other organic materials. Engineers use it to determine and detect the location of underground utilities and pipes, changes in strata, air pockets, backfilled areas, bedrock, groundwater tables, etc.
Projects that require ground penetrating radar In NYC entail excavation projects, bridges, mining, buildings, etc.
The construction industry is growing and expanding daily. Several kinds of construction and building take place worldwide, be it commercial or residential. For the safety of citizens, amongst other reasons, there are guidelines that are followed throughout the construction process. With construction management and surveying comes special inspections. Special inspections are evaluations and surveillance of materials that are carried out to ensure the quality and proper placement of structures and technical connections required to build a good and strong building that is in accordance with the regulations guiding it. The special inspection involves observing the quality and materials necessary to ensure the coherence and solidarity of the structure.
The structural engineer in charge prepares a special inspection report to account for any material or whatever is required to ensure the strength of the building in question. The purpose of the special inspection is to ensure that the building is designed with all that it requires to resist extreme conditions that may damage the structure. For example, natural disasters like earthquakes, hurricanes, etc., are considered in the special inspection report to design the building to withstand such disasters. Special inspections cover anything that may threaten the integrity of the building like pavements, foundation, water control. Things like plumbing and the likes are not necessarily included in the special inspection report or statement.
If you’re working on a building project that requires special inspection, here are some steps you should take to ensure that you are on the right path.
Steps to take for a successful special inspection
Ensure that all non-conformance materials are resolved immediately. If left unresolved, it may lead to the demolition of the property. Lastly, Ensure that your special inspection engineer submits a sealed and signed letter of total inspections carried out to the project owner, designer, and building official. After this is done, you will be required to apply for the final certificate of occupancy. Carry out a local online search for special inspections ins your location. For example, special inspection services, NYC.
If you’ve ever visited a building site in New York City, you’ve probably noticed that a certain group of folks comes around to inspect the progress. Occasionally, you’ll notice them drawing the workers’ attention to issue orders and rules. These are a team of construction inspection services in NYC, and their job is to ensure that a project does not deviate from its original plan.
A skilled and thorough inspection is one of the most important parts of a quality construction project. Routine inspection is required in any construction project. Inspections necessitate not only technical expertise, comprehension of the materials and methods to be used. But also sound judgment, diplomacy, and effective communication.
Let’s discuss the functions of special inspection services in NYC and why construction inspection services must be a part of the project team.
The project manager, a member of the contractor’s existing team, or an altogether distinct consultant may provide special inspection services in NYC. They, like every other project team, ensure that the project follows the plans and is compliant with all requirements, standards, and regulations. They try to bring the product up to the original standards, and if necessary, make changes before giving it to the client.
The use of specialized inspectors may be required due to environmental policy, on-site waste management, accessibility, and other characteristics of a project. Construction inspection services may be provided by a team of specialist inspectors for various departments, depending on the complexity of the project. These inspections may occur during contract review and signing, as well as pre-contract meetings and client onboarding.
The fundamental function of special inspection services in NYC is to ensure that projects adhere to the designs and patterns presented to the client before the start of work. Inspections are a way to ensure that the quality of completed construction work is up to par. As part of the overall contract administration procedure, specific inspections are carried out.
Construction inspection services in NYC include:
Construction inspection services in NYC employ effective inspection techniques for different construction projects, providing thorough and accurate documentation – electronic, written, and photographic – for the work.
Designing a structure that can meet design requirements with a minimum amount of materials is significant to control the project cost, meet the codes, and get the work done timely. For this, structural engineers are hired by the owners. Hirani Engineering and Land Surveying is a reputed multi-disciplinary consulting firm in surveying, engineering, and construction management. We have highly skilled and trained team of structural engineers to provide the best residential and commercial structural engineering services.
Our structural engineers are licensed and certified professionals who are well-trained to analyze various factors that exert force, such as wind, temperature, gravity, and pressure on the building, to determine whether the structure can hold and resist these forces or not.
Structural engineers play a significant role in the construction of any building. Remember, they are not the same as inspectors, architects, and contractors. The inspectors are trained in detecting the early signs of the problem, while structural engineers can easily analyze the severity of the problem and cause of the problem. They make sure the structure can resist the pressure and loads on which the building is supported.
Following are the key reasons to hire professional structural engineers;
