In construction projects, it’s often necessary to measure various angular and distance measurements to a high degree of accuracy. This is only possible using equipment with the right capabilities, protections, and workflow integrations.

This article is for construction professionals planning their next big project or looking for a quick and cost-effective solution. By analysing the top laser surveying equipment, we hope you’ll have all the information you need to achieve your construction project goals.

Different types of lasers for construction:

• High accuracy scanner, either SLAM or terrestrial
• Laser level
• Pipe laser
• LiDar

With the huge range of options available to construction professionals, it can be difficult to know what laser equipment is most effective for any project. Choosing between lasers that offer general utility, hyper-precise laser scanners, and specific supporting products can be made easier by considering the following:

1. Establish site requirements – Refer to any length and height information relating to your site areas to inform the maximum distances any lasers will need to measure. Each laser will have a maximum operating range, so make sure you pick a product that can service your site.
2. Assess laser level accuracy – You must choose a laser that can complete measurements to the appropriate degree of accuracy. Laser level precision is linked to the size of its beam per metre (for instance, 0.2mm/m). For laser scanners, it’s also important to consider the number of scans per minute.
3. Equipment durability – Construction sites can be challenging environments for delicate equipment due to the conditions.
4. Ease of use – Even experienced surveyors and setting out engineers can benefit from easy-to-use equipment. Look for products with intuitive interfaces and controls that can be operated when wearing gloves and other forms of PPE.
