    I have the same problem with our BC wanting to charge to inspect structural engineer specified strengthening works. Not wanting conflict between my LBC I have passed the matter to NAPIT to investigate. BC involvement adds an unnecessary additional layer of complexity to the installation process...

    Planning / Building Regs Article
