Hi Brendan,

Please see below responses:

1. This report is not yet available. The testing has been completed and we are aiming to issue the report prior to closure of tenders. If this doesn’t occur, clear assumptions in your submission will be required to assess tenders fairly.

2. The correct depth is as per the drawings. Please amend the BoQ accordingly. Note the BoQ was provided for information purposes only and the Tenderer must be satisfied their submission covers all Works required under the Contract.

3. Please add a line item to the BoQ within the provisional section at the end. Please note this is a Lump Sum tender hence this item must be provisional.

4. Please add a line item to the BoQ within the provisional section at the end. Please note this is a Lump Sum tender hence this item must be provisional.

5. Please add a line item to the BoQ to account for this. Note the BoQ was provided for information purposes only and the Tenderer must be satisfied their submission covers all Works required under the Contract.

6. This is an error.

7. The house will remain occupied and provision must be made to maintain access for this resident. The design incorporates a temporary access to the driveway to tie into the northern leg of the roundabout which will be this resident’s access until the site is developed.

Thank you

Question:
1. Can Council please supply the electronic 12D models for the existing terrain, and the design model for the roundabout works.

2. Can Council please supply the information on the electrical relocation works.

Hi Brendan,

Additional files have been added.

Thank you

Question:
Can Council please clarify the following:

1. Thank you for the CAD file for the existing terrain. However, given the tight timeframe given to complete this tender, we really do need the CAD file of the design model as well please. Please provide the design model as soon as possible.

2. In order to do our traffic staging, we need to know urgently if the existing house on Patricia St needs to have access maintained to it throughout the construction of the roundabout. Please let us know as soon as possible.

3. There is also a small box culvert 450 x 300 included in the drawings. Please advise the item number in the BOQ for small box culvert 450 x 300 and end structures.

Hi Brendan,

Please see below:

1. Additional files will be uploaded tomorrow morning

2. The house will remain occupied and provision must be made to maintain access for this resident. The design incorporates a temporary access to the driveway to tie into the northern leg of the roundabout which will be this resident’s access until the site is developed.

3. All stormwater other than the large box culvert is lumped into the ‘Stormwater Line’ item of the BoQ. Note this is a Lump Sum tender and the tenderer must not rely on the BoQ provided. The tenderer may add any items it sees fit to ensure the BoQ submitted includes all Works required under the Contract. Variations will not be considered for BoQ inaccuracies and the Priced Bill of Quantities will be used solely for assessing progress of the Works and possible variations.

Thank you

Question:
Can Council please advise the design vehicle along the highway - will they be Semi Trailer or B-Doubles?

Hi Brendan,

For traffic management considerations the Bruxner is an approved B-double route for design purposes turning paths for 26m B double straight through movement and 19m semi for all other movements are required.

Thank you

Question:
MJ Smith Ground Preparation Pty Ltd will have a representative attend the site meeting on Friday 6th December

Hi Michael,

This has been noted.

Thank you

Question:
Can Council please clarify:

In relation to the Undertakings to be provided by the Contractor, Contract Items 33 & 34 both state $1,000,000.

Usually this is 5% of the Contract Sum for Contract Item 33, and then reduced to 2.5% of the Contract Sum for Contract Item 34?

Could Council please amend this as $1,000,000 undertaking for a project of this value is an extremely high percentage.

Answered on 04/Dec/2024 04:03 PM:


Hi Brendan,

This a requirement from Transport for NSW under the Works Authorisation Deed. Council has unsuccessfully requested that Transport for NSW amend this requirement. Councils preference is for a conforming tender to be submitted however a non-conforming proposal as to how this maybe efficiency addressed will be considered.

Thank you

Question:
We would like to request an extension of time of 1 week for this tender due to concurrent commitments.

Answered on 04/Dec/2024 04:04 PM:


Hi David,

Given delays and size of project Council have extended the closing time to 12 Noon Monday 6th January 2025.

Thank you

Question:
As previously discussed, the design model is required for the traffic staging for the roundabout construction, and for the quantity checks for the lump sum contract. We understand RVC is trying to obtain this for us. We respectfully request an extension of time of 1 week for the tender submission to allow enough time to do the traffic staging and consequential methodologies and costings. On receipt of the design model files, we will need more than 2 weeks to assemble a comprehensive tender.

Thank you.

Thank you

Question:
Couple of questions please:

*Can you please confirm if you are working to TfNSW R83 / R82 specifications ?

*What concrete and compaction testing requirements are mandatory for this project?

*Is there a detailed electrical design component? When speaking with electrical designers they have mentioned there would be substantial electrical lighting required for a roundabout on the Bruxner Highway.

Answered on 04/Dec/2024 03:37 PM:


Hi Robert,

Please see below responses:

- Confirming TfNSW IC-QA-R83 and IC-QA-R82 are the specifications for the concrete roundabout component of this project.

- As per the abovementioned specifications

- Electrical design drawing ECN-098112 has been uploaded. Stage 1 only works as shown on the plan will be part of this project. These works include relocation of existing power and lighting to roundabout and adjoining roadway.

Thank you

Question:
Another question please:

* 5 cell box culvert structure, would have expected culverts to be laid on recessed concrete slab, culvert legs down. Is this a full box culvert design?

Answered on 04/Dec/2024 04:01 PM:


Hi Robert,

- Yes, it is expected that a recessed concrete slab be constructed as the base for these box culverts. Refer to attached for detail of this base slab, noting that there will be no link slabs (will be 5 x precast cells laid side by side as per drawings).

This detail will be incorporated into an IFC set for the project and issued to the successful Contractor.

Thank you

Question:
Can Council please clarify the following:

1. Please confirm if the Linemarking for this roundabout will be thermoplastic.

2. Thank you for the 2-Dimensional Design Model. However, we were actually requesting the 12D model or 3-dimensional model. Would council please provide the 12D or .dwg files for the design model urgently please.

Answered on 04/Dec/2024 03:47 PM:


Hi Brendan,

1. Yes, all linemarking is required to be thermoplastic or two part cold applied plastic material in accordance with TfNSW specification R145.

2. File 'Bruxner RAB CAD BASE.zip' has been uploaded to refer to

Thank you

Question:
1. Thank you for supplying the .dwg files. Our survey manager has searched through all the files, and unfortunately still cannot locate the 3 dimensional design model. He has issued the following explanation:

“Please request the 3D model, preferably in 12d format, including alignments, design road strings, pavements, and design TINs. We see that you are using 12d Synergy for your document management, which could indicate that the designers are also using 12d Model to produce the design model. We work in 12d and can ingest 12da files. If they contact the design firm and request a 12da of the full project including the original survey that would be ideal.” I hope this helps.

Thank you.

Good Morning,

Please see uploaded file TIN DESIGN-DWG

Council also has a file 241121 3D STRINGS & TINS.12daz but Vendor Panel is not compatible with file extension .12daz, this file is available to be emailed upon request.

These files include all alignments, centre lines, control lines, strings, existing ground level (brown lines).

Please note it doesn’t include pavement as pavement design has not been finalised. The depths in the BoQ are indicative only at this stage.

Thank you
