Worker safety on construction sites

Employee Safety on Construction Sites Is a Top Priority

In any construction environment, you are going to be warned that safety precedes. Building requires the use of heavy equipment and machinery. Everything is carefully orchestrated to complete each job safely, and each person involved has specialized abilities to do his/her part.

You probably have heard about accidents on construction sites. That is why it is so important that safety is the major issue on a construction task website, like this wonderful site;

Security is important at any job site, but numerous niches beyond building and manufacturing don’t always handle the customized and heavy equipment. Did you know that there are over 2 million workers that work on scaffolding often? This statistic alone can inform you that everything about the scaffolding needs to be exact. I suggest, these individuals are in some cases hundreds of feet in the air.

Crane operation on construction sites prevails. Crane day implies that heavy building materials are being moved and added to the structure. It’s not the the structure and security in operations that is essential, however likewise the cleanup. All kinds of injuries can happen if a site is not kept clean.

On any typical day, there are approximately 252,000 building sites in the US. These construction sites employ practically 6.5 million employees typically collectively.

Back to scaffolding as an example, it needs to be snugly planked and making use of quality grade product. It is inspected, and afterwards it is checked once again at periods where needed. This is done prior to each shift. You can picture how any of these steps left out can suggest terrible consequences for the employees involved.

The safety likewise definitely landed on the workers themselves. No horseplay and lackadaisical behavior is permitted. Employees have to be on alert and be concentrated on their jobs.

Once again making use of scaffolding as an example, you need to comprehend that there are other crucial safety demands. When it comes to construction, this assists you be aware how safety runs deep. For instance, the scaffolding cannot be within a specific quantity of feet from a power line. The rope used in scaffolding treatments has to be of a certain grade and safeguarded from the elements. Much enters into to guaranteeing employee security on construction websites.

In any construction environment, you are going to be made conscious that security comes. That is why it is so essential that security is the primary issue on a construction task website.

Security is vital at any task site, but lots of niches outside of building and manufacturing do not constantly deal with the heavy and customized devices. Crane operation on building sites is typical. Much goes into to ensuring worker safety on construction sites.

Location of Rebar in a Reinforced Concrete Structure Is Very Important While Carrying out Modifications

Concrete has a very high compressive strength compared to its tensile strength which is very low. It is possible to increase this tensile strength by introducing rebar in to concrete to make a reinforced concrete structure which can then take both tensile and compressive stresses and make for structures that have strength and durability.



Rebar location service  reinforced concrete needs to be put at very specific locations so that it allows the structure to have the required tensile strength. Building codes determine the distance this rebar needs to be at from the surface of the concrete. Rust formation can cause rebar to lose its form and strength and thus affect the strength of the reinforced concrete structure.

Quite often it is necessary to create new ducts or holes in a reinforced concrete structure to position services or other utilities. When this requires the concrete structure to be drilled through or partially, it is very important to make sure that any such modification is not hampered by the presence of the rebar. It then becomes very important to know the exact position of the rebar, so that any drilling or breaking done does not come across a rebar. While this can negate the entire process of installing new utilities, because of this obstruction, any damage to the rebar can severely affect the strength of the structure.

rebarTechnologies are available that allow the location of the rebar in concrete to be pinpointed, without any necessity for damaging the concrete to locate the rebar. These concrete scanning operations use ground penetrating radar to locate rebar. This allows the exact location for the rebar to be established so that any subsequent operations can avoid damaging them. There are times, when a structure is showing signs of distress, and at such times one of the first things that engineers do is check on the position of the rebar, as any shift from previously designed parameters can lead to weaker structures. Location of rebar in concrete can help engineers to assess the soundness of a structure.

Rust formation can cause rebar to lose its form and strength and thus affect the strength of the reinforced concrete structure.

It then becomes very important to know the exact position of the rebar, so that any drilling or breaking done does not come across a rebar. Technologies are available that allow the location of the rebar in concrete to be pinpointed, without any necessity for damaging the concrete to locate the rebar.

Concrete Scanning Can Help to Locate Utilities Who’s Positions Are Not Known




When you need to penetrate a concrete structure for installation of utilities or other reasons, you need to accurately determine the position of the reinforcement bars that are always part of a concrete structure. This is where the techniques used in concrete scanning can be of enormous help and enable you to pinpoint locations so there are no other problems when undertaking further work.

Concrete scanning can not only help to locate rebar, but also locate cables and conduits. It can estimate the depth ofconcrete scanning 2 the slab, detect voids and other utilities. This technology is also very much in use to detect underground facilities and utilities in areas that have been carpeted over by asphalt or concrete, or are under open ground. Thus helps to reduce chances of disruption of services. Recently, wrong utility maps led to a major 120 inch water main located 200 feet below ground being damaged by well drilling equipment. This led to major disruption of the water supply, major problems in its repair, and other inconveniences that could have been avoided by the use of proper concrete scanning equipment.

Concrete scanning uses ground penetrating radar to locate and act like an X-ray of the area being served. Such concrete scanning or ground penetrating radar has also been used in archaeological projects, so that objects below the earth and in digs are located, their shapes known and likely depths of excavation required, are known.

The Advantages of Using Ground Penetrating Radar to Figure Out Concrete Slab Thickness

Ground penetrating radar is a valuable tool for identifying concrete slab thickness easily along with accurately. Determining slab thickness is important in seeing how concrete pavements will perform over their service life. Be aware that even a reduction in the thickness of the slab by less than 1 inch can cut in half its service life. Computing the thickness of concrete slabs is also essential in determining if contractors have complied with the project specifications whenever developing concrete pavements.

GPR is technology that is currently being widely used in many states within their pavement evaluation systems, including North Carolina, Texas, Florida, Michigan and Louisiana, plus several European countries like the UK, Finland and Denmark, with much success. The radar sends quick pulses of radio waves straight into the concrete and then uses the arrival time along with strength of the returning echoes to calculate thickness along with properties like moisture content. However, GPR might not be able to make correct measurements if there’s not enough contrast in between the concrete along with the underlying base.

What are the advantages of using GPR in computing concrete slab thickness?

1. Thickness data from the GPR may be right away imported directly into pavement management systems to enable them to determine the rest of the life of the concrete pavement and also determine the right maintenance and also repair actions. Radar readings can end up being changed into graphical representation for simple interpretation or as ASCI file output.

2. Measurements can be performed by GPR equipped cars with minimal disruption to regular traffic because there’s no longer any need to shut down lanes while measurements are generally being taken. Cars can cover around two hundred miles each day of pavement at typical highway speeds. And automatic data collecting considerably cuts down on the time necessary to complete the survey.

3. The price of GPR is much more affordable compared with conventional methods of identifying slab thickness for example taking core samples. Concerned agencies possess the option of purchasing their own equipment and training personnel to man it or even contracting services from service providers, depending on the spending budget available to them for these functions.

4. Highway personnel tend to be totally safe whenever taking measurements because they are no longer subjected to dangerous situations for example high-speed traffic, inclement weather or even pollution.

5. GPR has a high range of precision within its measurements of concrete slab thickness. With respect to the type of layer being calculated, you may enjoy accuracy within range of 3 % to 5 % (for brand new asphalt). However actually calculating thick granular base may give results precise to inside range of 8 % to 15 %.

How To Select Ground Penetrating Radar Services

Ground penetrating radar services happen to be versatile enough to be used for a variety of applications, ranging from discovering invisible utility pipes as well as conduits within concrete slabs to finding archaeological treasures in excavation sites. This specific technology basically draws a picture of what is hidden underground simply by sending pulses of radio waves directly into the target area. When the waves encounter a blockage, they produce echoes that can be graphically displayed on the GPR unit’s screen.

There are generally 3 basic types of data which may end up being given by a ground penetrating radar device. The standard is 2D data, which is actually the raw data that is produced by the GPR and appears as a series of roughly-drawn lines on the screen. 3D data is created by merging numerous 2D readings to develop 3D picture. Finally, point data is created when the GPR is actually coupled with a global positioning system unit. The coordinates produced by the GPS are usually blended with the GPR data to create as-built drawings upon CAD or perhaps GIS software.

Ground penetrating radar services normally take about three procedures to a GPR survey. The very first is to basically examine the site for clues to the desired targets, and then use this as a starting point for a much more detailed search. The GPR is moved across the suspect area until finally the target is found, and then marked on the ground or even its coordinates logged using a GPS. With mark out approach, a more systematic search is undertaken by dividing the search area into a grid and then relocating the GPR throughout each individual square within orderly search pattern. Ultimately, there is actually the generation of a 3D map of the search region, which may be created using the information produced by earlier searches while using the first couple of approaches.

Whenever hiring ground penetrating radar services there are usually three primary considerations to bear in mind:

1. What sort of technology are they using? You will wish to make use of service that uses the most up to date GPR devices available to ensure that you get the final results you’ll need.

2. Do they have a highly trained staff? While it is simple to run the GPR unit itself, you will still want to have a skilled technician on hand to interpret the readings to make sure that practically nothing is missed.

3. Precisely how long have they been operating? You will want to retain the services of a service that is well-established in your town to make sure that they are reliable and may provide you with the services that you need.

The Many Uses Of Ground Penetrating Radar

Ground penetrating radar just recently promised to become vital in the solving of one of America’s most enduring unresolved secrets: the ultimate fate of former Teamster’s President Jimmy Hoffa. After a tipster informed Roseville, Michigan cops that he spotted a body being entombed underneath the driveway in July 1975, just one day after Hoffa went missing, the police utilised GPR and then identified an “anomaly” beneath the site. The fact is, dirt specimens taken for tests confirmed that no human remains were entombed there, and the answer to Hoffa’s disappearance is still to be discovered.

For some customers, nevertheless, GPR is often utilised for much more mundane uses. For example, GPR technology can evaluate if there exist underground water mains or maybe utility lines in construction locations that may be damaged during excavation and therefore which could result in work downtime as well as costly delays because of repairs to the damage caused. Moreover, it will identify the existence of obstructions such as reinforcing material and voids, that could cause worker injury. Also the expense of utilising the technology is ultimately more economical as compared to the price of getting to shoulder the expense of injuries and structural damage.

Ground penetrating radar makes use of high frequency radio signals transmitted into the ground in order to pick up on underground objects. Their presence is depicted once the signal comes back to the receiver as echoes and then the data are displayed on the GPR display screen.

The depth and position of the physical objects are depicted through the amount of time it takes the echo to travel to and from it. The data are then translated by the technician as to whether the thing is the root or subsurface infrastructure. Software could also be used to turn the raw data into 3-dimensional maps that enable the attributes to become more easily interpreted since they are presented in a more visual manner.

Many types of ground penetrating radar models can be used based on the item being found as well as the surface type on which it is being used. Like, for anyone who is finding rebar in concrete floor, the 1,000 MHz high-frequency GPR is used as that will give high resolution for as much as Twenty four inches in depth. Alternatively, if you need deeper penetration, just like if the radar is going to be utilised in ground soil, reduced wavelengths from 12.5 MHz up to Five hundred MHz are generally utilised which could provide depth range which will go from a few inches up to hundreds of feet.

What Are The Differences Between Concrete X-ray and GPR?

Concrete X-ray is in reality a inaccurate term as many tradesmen use it to refer to ground penetrating radar. Causing misconceptions is the reason that, even though concrete radiography is significantly being replaced with GPR, the outdated technology is still utilised. Concrete radiography comprises of taking x-ray pictures of concrete slab to find out where post-tension cables, rebar and also conduits are located inside it. The X-ray device can pass through as much as thirty inches inside of the slab and often even further depending upon the composition, and get quite in-depth pictures which are simpler to translate compared with GPR records.

Are there other differences between concrete x-ray and ground penetrating radar?

1. Cement radiography must be processed off-site. The final results of the scan are placed onto x-ray film, that still has to get processed prior to the outcome can be interpreted. Having GPR, the end results instantly are displayed on the unit’s electronic screen. Even so, most radiography services have mobile darkrooms that let the film to be|developed on site, furnishing you with the outcomes quickly.

2. Cement radiography uses both sides of the slab for reading, with one end containing the film and the other the reflector plate. Due to this, there are constraints with the thickness of the slab to be examined. If you have iridium-based radiography machines, you can check out a slab as much as twelve inches, while by using cobalt-based radiography you are able to scan the slab with a ma thickness of thirty-six inches.

3. Concrete radiography needs the operator to wear safety gear like a lead apron to ensure they are safe, also having an eighty foot space surrounding the slab making sure that onlookers aren’t going to be exposed to the radiation out of the x-ray machine.

4. Cement radiography is actually more expensive than GPR because of the higher cost of the equipment involved together with the wages of the x-ray specialist handling it. Conversely, the GPR operator can be qualified to deal with the apparatus just in one day, although you will also need an experienced technician in order to translate the results.

5. Concrete radiography can’t gather info on large work sites. To be able to acquire facts on larger slabs, you simply must continually set up the concrete x-ray equipment at various areas that you want to gather data. In comparison, GPR is a tool that can take scans of large work sites simply by being set up once.
