Soundproof, erroneous and large works.

Why is it called a mistake: On issues related to soundproofing or soundproofing and technical standards of soundproofing or soundproofing

Technical standards: Including standards for environmental materials, connection standards, negative noise standards, quality measurement standards.
Design and installation costs: For large soundproofing projects or soundproofing rooms, a reserve station package or entire grid station for large ME contractors. But due to the cost of the team, the cost of long waiting for funding, and the related costs, but when the item is checked, according to the volume from the beginning, the contractor finally selected a number of small units to reduce When the cost is reduced, the quality, as well as the subcontractors, is reduced. Finally, the project must have a quality loan from the measurement center.
With a small amount of funding you can fully qualify for loans from non-state centers.
The experience as well as the calculation method ensures the material standards as well as the connection standards, and finally a measurement unit under the management of the state is a complete product.
For us the experience of 15 years in the field of installation of machines, noise and accessories set standards to the top, we stand out for the VBB tower, Vietinbank tower, factory buildings. Ho Chi Minh City waste water treatment, we have more success than expected and how to overcome the mistakes to put forward a finished product.
For small or new contractors, just come to the profession by making a lot of profits or just to survive with social or professional scams.
For those who do not have professional qualifications but only social relationships, then the works are just as good and relative.
Can only install soundproof, can not operate the machine, can only do, but can not handle the risk of trouble.
Hence the contractor needs a better record or quality inspection by a technician, and technicians who do not have a basis for technical reasoning never produce a good product.
The starting point for a job is to love the work, for the purpose of striving and learning to be able to give good products for the country and for society.
