Anyone knows how the process work if the contractor is using hdb for disposal? I called up hdb and apparently hdb help to dispose for a flat fee (unlimited times apparently) but hdb do not do haulage for my council. Contractor is charging me for the following using private disposal and haulage. Sand is quoted separately so I am trying to find out if cheaper if I get hdb to do the disposal and haulage Lumpsum for mobilising hacking labour and haulage of materials - $1,200 Supply labour for hacking walls and disposing of debris (about 3 bedroom walls) - $714 Additional labour for disposal and haulage of sand for tiling - $450
