Question:
The contract requirements in brief states that "Reinstate 150 mm Gravel Pavement Layer & Mix the stabilisation agent thoroughly with the existing base material to 200mm deep by full width of existing gravel road pavement".

The scope however states "Construct cement stabilised gravel floodway pavement 150 mm Thick (stabilised 3% by mass with low heat (LH) cement) to suit natural topography. Reinstate 150 mm Gravel Pavement Layer, compact, grade and trim to MDD min 98%"

Please confirm the depth of stabilisation whether 150mm or 200mm?

Question:
Good afternoon,

Please advise an Award date and a PC date for the execution of these works.

The document state the Tender price to be valid for 1 year, is it an indication that the works would need to be completed in stages and multiple mobilisations?

Thank you,

Question:
1.0 Please clarify if we need to allow for top up material prior to cement stabilisation. If top up material is required, please specify the depth in mm.

2.0 Do we allow for cement for 150mm depth or 200mm depth?

Question:
Q1. Item 2.1 of the specification: Preparation of the suitable mix design (3% LH cement) for approval by the principal. Is there a specific design parameters eg specified UCS limit?

Q2 Item 2.1 of the specification: Reinstate 150mm Gravel Pavement layer. Can you please confirm this is not importing 150mm thick gravel, placed on the floodways prior to any stabilisation.

Q3 Item 2.3 of the scope states the minimum density is “MDD min 98%” and item 2.3.7 compaction the minimum “Characteristic Dry Density Ratio” is 96%. I f you can please confirm the minimum density is 96%.

Q4 2.3 scope

“ Tenderer to carry out one test per specification” does this mean 1 test per patches, would a method specification be acceptable?. In a method spec we would determine the minimum number of roller passes required on the first patches to achieve the required minimum density. Then use this method for the remaining patches.

Q5 Is there a Bituminous sealing to go onto these floodways?

Q6 Can the patches be handed over to the shire once they have been trimmed?

Question:
Hi Team

Thank you for the responses provided to date. The documentation remains unclear as to the extent of processing and preparation required for material sourced from the borrow pits prior to use on site. Could you please confirm:

1. Whether the material is to be used in its natural state, or whether screening and/or mechanical modification will be required prior to use.

2. The current status of the material and whether it will be pushed up prior to commencement.

Furthermore, Addendum 1 notes 150 mm plus 50 mm embedment into the subbase layer, while Addendum 3 notes a further 50 mm top-up. On this basis, could you please confirm that the intended cement stabilisation profile comprises 50 mm embedment, 150 mm basecourse and 50 mm top-up, resulting in a total stabilisation depth of 250 mm or 200mm total?

Kind regards
