Q17. What does the City mean by “bolt on” rollers? Normally this item is
welded on. Can you please provide me with a better understanding of how
this works and what it looks like?
A17. The City recognizes that the rollers are usually welded on, but
perform onsite maintenance of the bins without a fabricating shop to
handle bins of this size or weight. This requirement is for ease of
maintenance and would be an in shop design change
Q18. We are not sure about a curved door at the rear – I’m only aware of
roll offs using straight-flush back doors.
A18. Please see diagram 6, please note, diagram is a two door design,

Q19. Page 15 – 12”, rear skid pads on front end bins – can you please
indicate to us what this is?
A19. Please see diagram 7 and 8
Q20. Can you please clarify if all of the bins are roll offs? Page 4 states this
tender is for the Supply and Delivery of Roll off containers but pages 14-15
states the minimum specifications for a roll off container and front end
container.
A20. This tender if for both roll off and front end bins.
Q21. On page 15 it states their requirements being standard open top with
wheels. Typically roll offs would have rollers as opposed to wheels so we
are slightly confused.
A21. Wheels are rollers
Q22. There are no formal dimensions on the specifications. We would like
to know the specific dimensions of each of the containers and possibly a
couple of pictures or drawings if they are available?
A22. The dimensions are industry standards for the various bin
types/sizes. The City is relying on bidders to construct the bins based on
their industry knowledge and previous experience fabricating equipment in
the waste field so should therefore know the industry standards.
Q23. Could you please specify the required weight capacities for each bin.
A23. Please construct the bins as specified. The specifications are set in
order to ensure longevity, structural integrity and durability and are not
necessarily based on the weights of the materials that they will be
carrying.
Q24. Will the amendment include an extension to the submission deadline?
A24. No extension will be granted
