We have been told by the consultant that we cannot hang more than 300kg per square meter on the existing slab. Please provide fixing method along with structural calculation. Any further information required please contact me. Info from management Please refer attached structural load parameters which is 0.5kPa. Please note that do not proceed with chandelier suspension until the above are submitted. Please re-refer attached. [login to view URL]
