All tools require proper care and routine maintenance for them to work correctly, and laser levels are no different. They are precision instruments and will give many years of service if cared for properly and serviced regularly. Here are some points to remember to extend your laser level's life and accuracy.

Proper storage

• Your instrument should always be stored and transported in its specially designed carrying case, which, in turn, should never be used as a temporary tool kit.
• Moist instruments should be wiped dry before being put away. Damage caused by condensation is one of the biggest problems we encounter in our service department. A wet or damp instrument should never be stored in this condition. See the below picture for damage to the main PCB board due to the device being stored while still wet.

Cleaning 

• lf the instrument is equipped with any kind of optical glass on the outside, these windows must be treated with care. When cleaning the glass, remember to always rinse it first with clean water and then dry it with a soft, clean cloth. Never use anything abrasive to clean the glass. If the glass surface gets scratched, the scratches may distort the laser beam and lead to incorrect readings.
• Never clean with pressurized air, since dust particles in the air can lead to a "sand blasting" effect
• lt is essential to keep plugs and clamps for electrical connections dry and clean as well.

Batteries and charging

• Aways use a fully charged battery or power adapter. Charge the battery when the laser is not in use. If you notice that the battery is overheating during the charging process, you unplug it. Give it time to cool (20 minutes or so should be enough) and then plug it back in. Non-rechargeable batteries should be disposed of immediately after they deteriorate.
• You should never carry a laser instrument by its cable, and a laser instrument should never be connected to a car battery that is still connected to a car.
• When your instrument is not in use we recommend that you store it with the batteries removed from the instrument and accessories e.g. detector and remote control. If the batteries leak when the instrument is not in use for a prolonged amount of time they can cause a lot of unnecessary damage

Final thoughts

By following these few easy steps you can ensure longevity and accuracy of your instrument. Proper maintenance along with regular calibration will help you keep your instrument in good working condition. Take care when handling your laser and don’t skip yearly maintenance, so you can avoid any problems when tackling projects that require precision.

However, the cost of ongoing training can be outweighed by the many benefits. Investing in ongoing training can help companies to reduce the risk of errors and inaccuracies in their surveying work, which can save the company money by reducing the need for rework or revisions, which can be costly and time-consuming. For example, if a surveyor makes a mistake while conducting a land survey and the mistake is not detected until after construction has begun, it can cost the company thousands or even millions of euros to correct the error.

Investing in ongoing training can also improve the efficiency of surveying work reducing the time required for data collection and analysis. This can result in cost savings for the organisation as the same amount of work can be completed in less time. For example, if a surveying team can complete a project in two weeks instead of three weeks the organisation can save money on labour costs and other expenses associated with the project.

Finally, investing in ongoing training can improve safety and reduce the risk of accidents on the job. This can save the organisation money by reducing the costs associated with workplace injuries such as medical expenses, workers' compensation and lost productivity. For example, if a surveyor receives training on how to properly use safety equipment and prevent falls, the organisation can reduce the risk of injuries and avoid the associated costs.

The Importance of Certification

Certification is an important aspect of ongoing training for users worldwide. It demonstrates that a surveyor has the knowledge and skills necessary to perform their job safely and effectively. It also provides assurance to clients that the surveyor is qualified to perform the work required.

Nedo lasers are known for their precision and reliability, but occasionally, they may encounter power on/off issues. This article shares a practical approach to diagnosing and resolving such issues in the Nedo Laser Model LINUS1 HV without the need to send the unit back to the manufacturer for repair.

Initial Experience with Nedo Laser Repairs

A few months ago I faced a challenge with a Nedo laser that wouldn't rotate. After unsuccessfully attempting to fix it, I contacted the Nedo service centre in Germany. They suggested it might be a software issue and quoted a 60 Euro fee for a software update. With the customer's approval, we sent the unit to Germany for repair. However, Nedo's repair estimate was a surprising 700 Euros which led to the customer declining the service. This frustrating experience motivated me to find an alternative solution for future repairs.

Troubleshooting Power On/Off Issues

When I received another Nedo laser with a power on/off issue, I was determined to repair it myself or inform the customer that it was unrepairable. I began the diagnostic process by testing the battery which proved to be in good condition and not the cause of the problem.

Identifying and Resolving the Problem

Upon further investigation, I found that the main switch PCB board was likely the culprit. I sourced a replacement PCB board from Nedo Germany for 15 Euros with a 30 Euro shipping fee. I then remembered that we had some push buttons in our old spare parts inventory which could be used for the repair. After locating the appropriate button, I replaced the faulty one on the PCB board, successfully repairing the laser.

Customer Satisfaction:

After reassembling the unit I contacted the customer to inform them that their equipment was fixed and ready for collection. They were pleasantly surprised to learn that I had repaired the laser at my service centre without the need to ship it to Germany. This efficient and cost-effective solution left the customer highly satisfied with the outcome.

Conclusion

By developing a thorough understanding of the Nedo Laser Model LINUS1 HV and its components, it is possible to diagnose and resolve power on/off issues effectively without relying on the manufacturer for repairs. This approach saves time, reduces costs and enhances customer satisfaction.

We're going back to basics today with a quick explanation on what GPS and GNSS stand for, and which term should you use when referring to navigation systems.

The Global Navigation Satellite System (GNSS) is a collective term for satellite navigation systems that deliver autonomous geo-spatial positioning with global coverage. This umbrella term encompasses various systems including GPS, GLONASS, GALILEO, BEIDOU and other regional satellite constellations. The primary benefit of accessing multiple satellite systems is enhanced accuracy, redundancy and constant availability.

Although satellite systems rarely fail, GNSS receivers can switch to alternative systems if one is compromised or if the line of sight is obstructed. GNSS receivers are compatible with signals from any positioning satellite, not just those within the GPS system. As a result they offer more accurate and reliable positioning than GPS alone.

Is using the term GPS instead of GNSS incorrect?

People often use the term "GPS" instead of "GNSS" due to greater familiarity with GPS as a standalone system. Developed and maintained by the US government, GPS is part of the GNSS network catering to both military and civilian uses. It comprises a series of satellites and ground control stations that deliver precise location and timing data to users worldwide.

GNSS includes other satellite-based navigation systems such as GLONASS (Russia), Galileo (Europe), BeiDou (China) and QZSS (Japan). The primary objective of GNSS is to provide global location and navigation information to users.

The number of satellites in a system directly impacts the accuracy of the location information it provides. While GPS has 31 operational satellites, GLONASS has 24, Galileo has 30 and BeiDou has 35. GNSS, excluding the GPS constellation, has a total of 89 satellites, contributing to its superior accuracy compared to GPS alone. Nonetheless, the accuracy also depends on factors like receiver quality and the presence of interference or obstructions.

What's the main difference between GPS and GNSs systems?

GPS is widely available and reliable, finding applications in industries such as transportation, agriculture and recreation. However, signal jamming or interference can affect its availability and reliability. GNSS offers more robust availability and reliability by using multiple systems. If one system fails, users can still access location and navigation information from others which is especially useful in areas with limited or unreliable GPS coverage.

Initially developed for military use, GPS is now operated by the US Department of Defense for both military and civilian purposes. Other GNSS systems like GLONASS and BeiDou were also created for military use and are managed by their respective countries' armed forces, raising concerns about potential signal disruption or jamming during military conflicts.

It's all about accuracy

The future of GNSS and GPS technology continues to evolve with advancements aimed at improving accuracy, availability and functionality. One major development in the field is the integration of various GNSS systems to form a multi-constellation system providing even more accurate and reliable location and navigation information.

In summary, GNSS and GPS are satellite-based technologies that deliver location and navigation information to users. While GPS is widely available and affordable, GNSS offers more comprehensive coverage and accuracy through the use of multiple systems.

The team at Unicontrol have really thought about their product and the useability of that product for the end user, in this case, the operator of excavators, wheel loaders, dozers, backhoes and finally, their GNSS Rover.

One of my favourite features is the Create Surfaces function, which allows the operator to quickly create a level by themselves using the information given to them on the drawing.

The Create Surfaces feature can speed up the process onsite and reduce the need for the contractor or engineers to provide 3D surface drawings to enable the machine to work. The system is constantly upgrading and meeting the demands of the customers. There are currently four options for creating surfaces. Read below for a quick introduction to these options.

Flat Surface

This option enables the operator to create a flat or level surface at a given elevation. The elevation can be entered by the operator in the app. For example, if the site plans show a FFL (Finished Floor Level), the operator can use this information to create a surface at the given elevation without the need to have an engineer set up a benchmark for them.

Surface From Points

This option enables the operator to create a surface from pre-surveyed points. Once the operator selects the points, the system automatically triangulates them, forming a surface as an XML surface file.

A simple scenario may be that the machine is excavating a site to formation level and there is a deep cut but there is no surface file on the excavator for the slopes. Using the DXF (linework) drawing the operator can survey points along that line at the desired depth. After the first points are taken at dig level, they can then survey points at the top level, i.e. from the boundary or a line for the top of slope. Once these points are surveyed the operator can then create a surface using the points in the Surface From Points feature.

The surface created this way will give the operator a level to work from with the required slope. This will speed up the productivity of the excavator as the operator will be able to complete the job in 1 pass.

Foundation Outline

This option works similarly to the flat surface. The only difference is that Flat surface is infinite, so wherever we go the level will remain the same.

With foundation outline we log/survey the outline of the foundation of the building and we can limit the surface to a certain distance outside the footing extremities.

E.g. If the machine was working on a building site with different floor levels we can set the foundation outline for each house numbering them as we go, all surfaces will be saved in the history of the project in the jobs menu making it easy to revisit the surface again.

Cross Sectional Surface

This is a new function being released soon that will allow the operator to create simple road designs, ditches, etc. using polylines. This function will create a cross sectional view which will create the surface between the line work and for the length of the linework. It’s a real game changer for anybody using Unicontrol 3D.

Summary

Using machine control will usually boost productivity by 30-50%, allowing machine operators to work independently while reducing the need for a survey engineer.

The operator’s ability to create simple drawings really streamlines the earthmoving aspect on sites. Unicontrol’s surface generation feature boosts productivity even more as the operator can create surfaces of any shape or form independently and accurately, and complete the work in the first pass.

Earthworks should be simple and Unicontrol is making sure that their machine control systems make it possible.

Based in Coe's Road Industrial Estate, Dundalk Fabrication & Coatings Ltd. is a specialist engineering company specialising in mild steel and stainless steel fabrication. Their expert team of Design Engineers, Project Managers and Fabricators provides turn key solutions from design concepts for commercial construction projects.

We asked their Site Manager - Eddie McArdle - about their work and why they decided to go with GeoMax surveying equipment and X-PAD field software.

What were the biggest challenges that your design and site teams faced?

When we first contacted Hitechniques in September 2022 our plan was to take on the site surveying and set out ourselves at a higher level. Our biggest challenge was getting information to the design team from the site and back again. We needed a more efficient way to share information about existing structures to be tied into new build, dimensions, heights of existing building elements.

Why choose Hitechniques ?

We wanted a system that would cover everything from surveying the site and getting the design drawn on the area available, to overlaying back on the ground. It had to be reliable and tailored to our specific needs. Hitechniques was able to cater for this.

We booked into training with Philip after a consultation with Roch on what we needed to achieve. They asked us questions on our upcoming projects and they came up with a tailor made plan to match our needs. The course was a very good introduction with theory and practical knowledge of the robotic total station and surveying.

From there, we hired the unit to trial. Once we knew it was the right unit for us, we purchased the full kit. We knew we'll be using it in a majority of our work and Roch went through the different options and provided case studies on long term and short term use. Buying outright made sense both logistically and financially.

What instrument did you end up purchasing?

The Zoom 90 Robotic total station pack with X-PAD software was the setup recommended to us. It brought all we wanted into one programme and enabled us to use it on site and set out all our points from the designers AutoCAD file, which was crucial for us.

We were able to survey the site, record finish floor levels, survey existing structural steel members and their connections. We could relay all of this information back with speed and accuracy and trust our own drawings to set out the new elements.

The main benefit of having the Zoom 90 is that we can create our own workflow on site. Once we have the site control and our bearings set up we can revisit the site, set up using the control stations and pick up where we left off. The day of string lines and using tapes to set out our holding down bolts and building lines is now all wrapped up digitally in the Zoom 90 Robotic total station.

What would you tell people thinking of buying new surveying equipment?

We would highly recommend Hitechniques as a company where you can not only purchase state of the art equipment but to get back up and technical support from their experienced staff. Having that safety net makes a huge difference, especially at the beginning when you’re still getting used to the new equipment and software.

Construction and surveying instruments are often exposed to very harsh conditions. Even though they are made from rugged materials and manufactured to specific standards, they can still be damaged by elements, dropped accidentally or even get run over by a truck or excavator. They can also stop working due to some mechanical or electrical issue that occurs with age, or even missed software updates.

Replacing instruments like rotary lasers or surveying GNSS rovers can be expensive, so it’s always worth looking into repair options first. In most cases experienced technicians can get your equipment repaired and back to you with minimal downtime and at a significantly lower cost.

There are a few instances though, when repair is not a viable option. Each instrument coming to the Hitechniques Service Shop is inspected thoroughly, so our technicians can make a list of repairs needed and parts that will have to be replaced. When examining an instrument, they take into consideration three main factors that need to be thought-through, before deciding whether to go ahead with the repair: cost, effectiveness of the repair and the age of the equipment.

Cost

It’s our policy to send repair estimates to each customer before we start working on their equipment, to check if they are ok with the price. Generally we leave the final decision to the customer and proceed with the repair if that’s what they want to do. In some cases, though, the equipment is beyond economical repair and we recommend replacing it instead. This happens if the predicted cost exceeds 75% of the value of a new instrument.

One of our customers has five electronic theodolites they purchased from us. Unfortunately a few days ago one of the theodolite fell down while working and got damaged. The vertical disc of the instrument was completely broken, the chassis was badly jammed, and the vertical angle was no longer visible on the screen. The vertical drive was also not working and the tribrach was bent.

With that much damage the cost of repairs would have been significant and exceeding the 75% of a new instrument’s value. Our technician suggested purchasing a new instrument and offered the customer a discount, if they were to buy from our store. The customer agreed to this offer and purchased a new device from us.

Effectiveness

Surveying and measuring instruments are complex machines built to deliver specific results. They are used by professionals relying on their accuracy and have to perform perfectly. Serious damage to the internal mechanism or electronic components can compromise the instrument’s ability to take accurate measurements.

While most parts can be fixed or replaced, sometimes it’s not possible to assure the same level of efficacy. In such cases it’s best to replace the instrument to avoid costly mistakes.

Age of the instrument

Not every professional needs the latest technology and some hold on to their trusty GNSS receivers or laser levels for many years. There’s nothing wrong with that and it’s great to see so many instruments performing outstandingly for long periods of time. Unfortunately, when such instruments are in need of repair, it can be difficult to find replacement for damaged or worn out parts.

Some final thoughts

When it comes to surveying and measuring instruments, the environmentally friendly “repair instead of replace” approach isn’t always a viable option. Technology becomes obsolete quicker, making repairs harder and more expensive because of complexity of work and poor availability of parts. It also puts more pressure on users to upgrade their equipment in order to stay ahead of the competition. Each case needs to be assessed individually before a decision is made, to assure it makes sense financially and is the best course of action for you and your business.

Beausang Plant Hire & Civil Engineering are a company based in Shanagarry North, County Cork. They specialise in residential projects using the insulated concrete framework.

Having previously hired units when needed in the past, Aaron and Thomas decided that it was time for a solution better suited for their workflow. Working on a new residential housing development, they were considering purchasing their own GPS rover unit.

After trialling three different brands to see which instrument would best fit their needs, they decided to go with the GeoMax Zenith60 IMU GNSS Rover. An on-site demonstration with our Technical Sales Expert - Roch - gave the team the perfect opportunity to try out the instrument along with the X-PAD surveying software, and they were impressed with its capabilities.

“The machine itself was superior to the others in terms of speed and usability, and offered the best signal by far at our site without the need for a base station”, says Aaron Beausang.

As many other customers, Aaron also appreciated Hitechniques dedicated support, which includes basic training on the equipment and unlimited technical support provided by our experts.

“Hitechniques team offered great support anytime we needed it when getting started with the new kit. I would highly recommend Hitechniques and GeoMax to anyone looking for a great product and equally good support.”

Beausang Plant Hire & Civil Engineering are continuously investing in new equipment to ensure highest quality and accuracy of work for their customers. When they decided to #switchtogeomax our team helped them pick the right surveying solution, and now we look forward to seeing their business grow.

Machine control is fast becoming a must have in the construction industry, increasing uptime and productivity by up to 50%. Machine operators don’t have to read the stakes visually anymore, they have the plans uploaded to a tablet right in front of them. 3D machine control uses tracking sensors and a receiver to get signal from satellites for positioning, enabling operators to put the bucket within 20 mm accuracy.

Unicontrol's 3D excavator, wheel loader and dozer machine control systems are relatively new to the Irish market. That being said, on a global platform Unicontrol already has 79 distributors across 26 countries, and over 1500 systems in operation. They are rapidly gaining recognition in the industry thanks to the user friendly, reliable system created with the operator in mind. Read below about what Unicontrol offers.

Noteworthy features of Unicontrol3D

• Four constellations as standard

While some competitors only use GPS and GLONASS, Unicontrol systems always have 35 to 45 correction satellites at their disposal. The system uses GPS, GLONASS, BeiDou and Galileo, making it easier to get a fixed position in harsh environments.

• Easy to use interface

Unicontrol3D with only 6 control buttons allows you to control your system without looking through drop down or hidden menus. every function is easily accessible and the software is highly intuitive, meaning that it can be used with only a minimal training. The software runs on a portable Samsung Android 8” rugged tablet, with a 10” also available.

• Heavy duty sensors and cabling

Unicontrol heavy duty sensors and cabling are designed with military grade materials.

• Fast acting IMU sensors

The sensors continuously track the machine’s movements in real time, ensuring highly accurate work each time. Unicontrol3D supports the articulated body, front arm and bucket sensors for wheel loaders as well as tilt rotator, swing- and dual boom for excavators.

• DXF and LandXML data formats support

Drawing requirements of the system are DXF for linework and LandXML for 3D surfaces.

• Can be used without GPS

Unicontrol3D will work if there’s no satellite signal available, making it a 2D system for simple excavations or grading. For example if working inside in a building like a warehouse where the roof is already on, the satellites could not see the machine. The system would work as 2D and allow the operator to grade out the area to the desired level.

• Surfaces functionality

With Unicontrol3D you can create surfaces from the machine, which means that there is no need for expensive 3D CAD software. For example, if the machine is working on a housing scheme the operator can create a simple level/flat surface from the cab of the machine. All he/she needs to do is to simply input the elevation they desire to work to. Let’s say the FFL of the house is 11.45m (elevation above sea level) and the build-up is determined by the engineer to be 0.5m. The operator could create a surface for formation level by entering the elevation value of 10.95 (11.45 – 0.5 = 10.95). The level that the site needs to be reduced to is set in less than 1 minute, and without the need of a surveyor installing a bench mark.

• Slope creation

A brilliant feature for pipelines, storm, foul, drainage etc. Most drawings for pipelines only show the centre of manholes as points, with Invert level shown on the drawing.The operator can use 2 of these points and enter the invert level of each. The system will calculate the grade between the 2 points and it will put a helpline in place so the operator will have a straight line between the manholes.

• Map out/survey functionality

Unicontrol’s software offers a feature allowing an operator to create his own simple drawings. Helplines can be drawn as straight lines or curved, Circles can be drawn using 2 points or 3, Points can be logged.

• Unicontrol Cloud

Unicontrol offers a simple system for transferring data between the tablet and the site office. Thanks to their cloud you can easily upload and share project data, assign machines and create projects. Also any logged points or surveys taken by the machine are saved here in the As-built.

• Remote access

Unicontrol3D allows you to grant remote access to the system. This allows support engineers to view the interface of the system and control the screen, so they can troubleshoot any issues quickly. This can also be used for training purposes.

• Warranty for your piece of mind

Unicontrol offers 2 year warranty on all hardware, and 2 year software updates with purchase.

Why choose Unicontrol?

Unicontrol3D will save time and money. It is an adaptable system that can be installed on excavators ranging from 2 tons to 120 tons. Can also be fitted to swing booms generally found on mini/midi excavators or knuckle/offset, or city booms found on larger excavators, and supports tilt rotator attachments.

In the next article we will be talking about creating surfaces in detail but before the article I will post some video content on how to create the different surfaces namely Flat/level surface, surface from points, or the surface of a foundation outline.
