In recent years, many civil works, factories, large-scale farms have used solar electricity placed on the roof, this is a clean energy source that can be used for production and living. operation and surplus power can be sold to EVN’s power industry.
In the future trend, solar power will be more and more widely applied, with only the initial investment capital, after a few years, the Investor can recover capital and continue to make profits from the following years (because because the lifespan of solar panels is usually 20 to 25 years).
And the Investor should also note that: In order to make optimal use of solar power with the maximum lifespan of solar panels, the installation of a solar power system on the roof needs to ensure the safety of the bearing of the solar panels. factory structure. Therefore, it is necessary to have a professional inspection consultant to evaluate the safety of the factory structure before installing the solar power system on the roof.
Please contact us, Vietsum Inspection will check the structure – the quality of the factory structure for the most accurate results.
Some pictures of projects that have installed a solar power system on the roof that have been structurally verified by VIETSUM and calculated to be safe enough to install solar panels on the roof of the factory:

So what are the steps to perform structural testing? Factory inspection VIETSUM would like to present to customers:
(Contents of outline and process of construction inspection at Vietsum factory inspection)
- Observation and inspection of the current state of the works: Manually, combined with visual observation, using camera equipment, steel rulers, measuring machines to determine the width of cracks.

- Check geometric dimensions: Check the site, measure, redefine the size of the building components, measure and draw according to reality. Made by manual method, measure directly with steel ruler, caliper.

- Check bolt connection: Check the number, diameter of bolts and tightness of the link. Made by manual method, measure directly with steel ruler, caliper, force wrench.

- Concrete strength test: Performed by manual method: drilling for concrete cores directly at the site and then machining, compressing at the laboratory, combined with non-destructive methods using bouncing machine.

- Checking quantity, diameter of reinforcement and thickness of concrete layer protecting reinforcement: Performed by electromagnetic method using Elcometer THD 331 machine in combination with drilling, manual measurement with caliper.

- Deflection test: Performed by surveying method, using leica electronic total station, measuring and determining the elevation of points, calculating the height difference.
- Check verticality: Performed by surveying method, using leica electronic total station, measuring and determining coordinates of points, calculating and determining verticality.

- Making report on construction quality inspection: Calculating and checking the bearing capacity of the structure; Proposing solutions to repair and reinforce (in case the work is damaged or not safe for bearing).
Some models for calculating the load bearing of structures according to Vietnamese Standards 5574:2018 and 5575:2012:
