Question:
Can council confirm if drainage sumps and outlet pits are required to be a RCP?

Answered on 08/May/2024 08:11 AM:


Can confirm that sumps and outlet pits are required to be RCP. Please refer to the Stormwater Drainage Design Handbook on Council’s website for further information.

Question:
Due to the resource constraint, our suppliers are finding difficult to provide the quote on time, could council please consider to provide an extension of time for 2 weeks?

Answered on 07/May/2024 02:10 PM:


Council is committed to delivering this project to agreed timeframes with Funding body, so we are unable to accommodate to request for extension.

Question:
The localised levelling/filling is that with surplus materials or imported materials

I see the duration runs from July 2024 through to April 2025, with this being such a abnormal year for being wet with such saturated fields running into summer would it not be advantageous doing this over the winter months in 2025.

There will be days and possibly weeks where we will not be able to access fields and plant, equipment and site offices will be stood down will there be recourse from LCC for stand down rates or possibility the cost of removing plant, site offices and equipment if it indeed floods

Answered on 08/May/2024 11:43 AM:


1 - Pending on site/soil constraints, levelling/filling can be both surplus and/or imported materials. Please note that surplus materials/spoil on site may not be suitable to spread evenly due to heavy clay content.

2. Unable to extend proposed timeframe due to completion dates stipulated as per funding agreement/body.

3. As per General Conditions of Tendering document - Delay Costs - The rate per day for delay costs is: $97

Question:
Are you intending to hold a site meeting to discuss your requirements with regards cleaning of drainage pits, localized levelling, grading of swales...

200mm non perforated outlet pipes from outlet pits to where and how long?

Question:
Do we provide turf for localised levelling and grading of swales

Answered on 08/May/2024 11:51 AM:


Turf will not be required in these areas.

Question:
Can the Blinding sand filter membrane be replaced with a geofabric (i.e not suggesting the entire trench be wrapped, just place a fabric filter layer on top of drainage stone in place of the sand ?)

Answered on 14/May/2024 06:26 AM:


Please provide a quotation as per specification using the sand blinding layer. However, should Tenderer(s) recommend alternative materials or methodologies, please submit a secondary non-conforming tender. The type/make of any geotextile to be used must be nominated.

Question:
Can council please confirm that WAE surveys need to be completed by a registered surveyor? The hourly rates required for the work of a registered surveyor as opposed to field measurements from contractor survey equipment / photos / diagrams given the non-structural nature of these works will add substantial cost to this project.

Answered on 13/May/2024 11:02 AM:


Council can confirm that WAE needs to be signed-off by the Contractor and their licensed surveyor.

Question:
Specification calls that there will be no variations with the event of encountering rock or other impediments within the soils,

we have no idea of what is under these fields and some of the discharge points are within the drip lines of several large trees with advantageous roots which don't work all that well with chain trenching. Can Council ensure there are no impediments under the soil that will not impact on having to change trenching methods?

Answered on 16/May/2024 01:13 PM:


Please refer to issued Addendum # 2 - Variations will be considered accordingly in the event of encountering rock, large stones or other impediments within soil profile.

Question:
The concrete pits and sumps do they have to be circular, or will 600 mm square pits suffice seeing that they are buried

Answered on 15/May/2024 05:24 PM:


Council will accept either round or square pits as long as the volume remains as per the design scope.

Question:
Can you please elaborate on the material specifications for 200mm piping?

"CPT" definition? corrugated perforated tubing? corrugated plastic tubing?

can the 200mm piping material be substituted for 225 slotted stormwater pipe ?(if required to be perforated.

Answered on 17/May/2024 03:56 PM:


CPT refers to Corrugated Plastic Tubing. The Specification for lateral drain pipe (Section 4.12) notes material to be used shall be ..” 100mm Ø perforated corrugated plastic tubing (Class 200)”.

For the sub-main the Specification (Section 4.11) notes: " The bulk of the sub-main pipe shall be 150mm nominal internal diameter perforated corrugated plastic pipe. Larger (200mm diameter) pipe shall be used in locations where greater flow rate is expected, as shown in the Drawings.”

In the few areas where larger pipe is indicated the requirement is for a minimum pipe diameter of 200mm. Either non-perforated smooth-walled pipe or corrugated pipe (perforated or unperforated) can be used in these areas.

Question:
The tender comments that we, the contractor will be responsible if we hit underground services yet there is no information available on current services. Can you please confirm this is correct? I think it is not reasonable to condition this. Thank you

Answered on 20/May/2024 06:49 AM:


Council can assist and highlight known services where appropriate. Council can confirm that Tenderers will be responsible for any sub surface investigation work including location of services through 'Dial Before You Dig' and/or any other means.
