What the buyer is requesting
Details
The Northern Peninsular Area Regional Council is seeking proposals from suitably qualified and experienced contractors to carry out works to expand the capacity of the Sewer Treatment Ponds in Bamaga.

Concept designs are attached. NPARC will accept variation to these designs.

The work involves the increase in size of the 2 primary lagoons and the addition of a 3rd secondary lagoon.

Other works include: New interconnecting pipework and valves; new bypass pipelines, relocation of a rising main, relocation of electrical wires, fencing and landscaping works.

The current STP must be able to operate for as long as possible during the construction works.

In addition, the contractor will provide an improved screening and grit removal system at the inlet to the STP. The design and type of these systems has not been specified and therefore the Contractor can propose the most cost effective system, with a focus on total life-cycle costs.

There is some desludging work required in the existing ponds. That work can be delivered as a variation, using unit rates.
Background information / Compatibility requirements
Details
Design drawings were prepared by GHD in 2016 but the works were not carried out at that time.

NPARC has now secured funding for STP Upgrades through the Residential Activation Fund program under the Queensland State Government.

It is expected that design, planning and procurement works will be undertaken in 2026, with construction planned for the dry season in 2027 (May to October).

Please refer to the notes in the set of drawings that were attached to this tender. There is important survey information, including the location of the Permanent Survey Marker.

We will be able to provide survey data and the GHD drawings in DWG format, if required.
Desired Outcomes ('Nice to haves', Conditions & Warranties, SLA's, Project benefits)
Details
The objective is to increase capacity of the plant to 6,000EP.
Questions asked by the buyer
Question 1 - [Required]
What experience have you had with this type of construction?
Question 2 - [Required]
Do you have sufficient capacity to deliver this project prior to October 2027?
Question 3 - [Required]
Please provide at least one Referee that would be relevant to this type of construction.

Question:
Hi NPARC, is there a BOQ available?

Answered on 21/Aug/2026 08:42 AM:


Sorry, there is no BOQ available.

Please see response to other question for a full explanation.
21/Aug/2026 08:28 AM
Question:
Could Council please confirm the following items to assist CCIS in preparing a compliant tender submission:

Bill of Quantities

Please advise whether a Bill of Quantities will be issued as part of the tender package?

Tender Briefing

Will a tender briefing be held for this project? If a briefing is scheduled, please confirm:

whether it will be conducted onsite or via Microsoft Teams;

whether attendance is mandatory for tenderers;

the proposed date and time;

the registration or RSVP process.

Answered on 21/Aug/2026 08:41 AM:
(edited on 21/Aug/2026 08:44 AM)


Sorry, no Bill of Quantities available.

The design was done some time ago and I cannot locate any other supporting documents.

That is why we have put this out as a design/ construct project.

I was not planning a Tender Briefing. It is difficult to get people up here and I don't think it is necessary for this project.

All responses are to go through Vendor Panel.

To assist with the pricing of the job, NPARC will provide all sand, gravel and fill required for the project free to the contractor.

This material will be extracted from nearby (less than 10km) quarries or laydown areas. The contractor will be responsible for collecting this material as required.

Council will also supply all concrete for the project - free to the contractor.

Quantities of these materials must be supplied to NPARC well in advance so that we can ensure they are available to the contractor at the right time.
21/Aug/2026 08:45 AM
Question:
Good morning,

could Council please provide the tender evaluation matrix that will be used to award this contract.

Regards

Answered on 21/Aug/2026 08:53 AM:


The tender will be assessed against the following criteria:

Price - 40%

Capability, Capacity, Experience of contractor (confirmed by Referees) - 30%

Engagement of local contractors and workers (as confirmed by IEOP) - 30%
01/Sep/2026 10:40 AM
Question:
Will Council be providing any further information for this RFT?

Answered on 01/Sep/2026 11:07 AM:


Sorry, but I have provided all the information that I can at this time.

Records and drawings are fairly sparse and hard to find up here.

If there is more investigative work that needs to be done, you can build that into your pricing.

Alternatively, you could recommend an early works package, that would then allow you to refine the costs for the main project.
01/Sep/2026 09:43 PM
Question:
Hi,

Could Council please confirm whether a two- or three-bedroom house can be provided to the Contractor, free of charge, for personnel accommodation during the construction period?.

Thank you.

Answered on 02/Sep/2026 07:55 AM:


Yes, Council will provide accommodation during the construction period. We have a number of accommodation options available, ranging from 3 bed homes to singe dongas. It will all depend on what's available at that time. Council will provide the accommodation free of charge to the contractor.
02/Sep/2026 09:35 AM
Question:
Can Council please take photos across the ponds from multiple directions and upload to vendor panel for viewing?

Answered on 02/Sep/2026 11:26 AM:


I have taken a number of photos today.

These will be uploaded to the documents area shortly.
02/Sep/2026 08:39 PM
Question:
I respectfully request a seven-day extension to submit our tender, moving the deadline to 17 September 2026. This additional time will allow us to finalise required documentation and ensure a complete submission.

Thank you for your consideration. I look forward to your response.

Answered on 03/Sep/2026 09:04 AM:


I will extend the deadline by 7 days,
04/Sep/2026 02:18 PM
Question:
Good afternoon,

Are there any tenderer returnable schedules along with BOQ's and contract specification documents available? Thank you.

Answered on 07/Sep/2026 09:38 AM:


No, sorry.

That is why this has gone out as a Design/ Construct project.

I found the old design drawings and have issued them for information.

But NPARC do not have teams of engineers who can prepare BOQs and specifications for Civil projects such as this.

I will be looking for tenderers to include that in their proposals.
05/Sep/2026 04:22 PM
Question:
Hi,

Could Council please clarify the extent of the 100 mm thick grout-filled revetment mattress shown on Drawing 42-18667-W003?

Please confirm whether the grout-filled revetment mattress is required:

1. Only locally at the inlet/interconnection pipework and splash pad areas, or

2. Continuously across the full length of the lagoon batters, as indicated in the lagoon cross-sections.

3. Is the grout-filled revetment mattress required only for the Secondary Lagoons and the Future new Lagoon?

Answered on 07/Sep/2026 09:41 AM:


Unfortunately NPARC does not have teams of Engineers that can provide those answers for you.

That's why this has gone out as a Design/ Construct project.

I provided the old design drawings for information.

I will be expecting tenderers to come back with those details in their proposals.
08/Sep/2026 09:22 PM
Question:
Hi,

Could Council please clarify the following items to assist us in developing the design basis and pricing for the Expansion of Bamaga Sewer Ponds project:

1. Existing STP Capacity

Could Council please confirm the current treatment capacity of the existing Bamaga STP?

2. Inlet Wastewater Parameters

Could Council please provide the available inlet wastewater flow and quality parameters, including where available:

Average Dry Weather Flow (ADWF),Peak Dry Weather Flow (PDWF),Peak Wet Weather Flow (PWWF),BOD5,TSS,TN,TP &Any other relevant influent monitoring data.

3. Lagoon Expansion

Could Council please confirm the design average and peak flows (ML/day or L/s) that should be adopted for sizing the expanded lagoon system?

4. Inlet Screening and Grit Removal Design Flow

Could Council please confirm the design flow rate (L/s) to be adopted for sizing the proposed new inlet screening and grit removal system?

Answered on 10/Sep/2026 08:53 AM:


Answers to all the above questions can be found in the Sewer Augmentation Report which is included in the Documents Section of this request.

This is the latest information that we have available.

None of the flow meters attached to the Sewer Pump Stations are currently working, but we are working on rectifying that now.

At present only Bamaga and Seisia pump to the Bamaga Ponds.

The intention is to transfer Umagico, Injinoo and New Mapoon to Bamaga as well. We are currently undertaking other works to make that happen.

So the intended ADWF and PWWF for all 5 communities would be relevant for the Bamaga Ponds. Use the 2032 projections from the attached report.
11/Sep/2026 04:47 PM
Question:
Good Afternoon,

Whilst we note that this tender has already received an extension to the submission deadline, the tendering space remains very busy right now and as such we are experiencing delays in responses from critical design and subcontract components. As such we would appreciate a further 1 week extension to the submission deadline if possible.

Thank you

Answered on 12/Sep/2026 09:06 AM:


James,

I appreciate that this is a difficult one to quote on because I did not have the depth of information available that you would normally have with this type of project.

Therefore I'm happy to extend by another week,
19/Sep/2026 11:55 AM
Question:
Would Council have a tip truck and excavator to load out of town materials required to deliver to site as required free of charge?

Answered on 21/Sep/2026 07:09 AM:


Council does have some plant and vehicles that we can lend out to the project, but only on a short term basis, as our own work crews also require those vehicles and plant for their works.

It would be safer, from a programming point of view, for the contractor to bring their own plant and vehicles to Bamaga.

Alternatively, there are two civil contractors in Bamaga who can provide those items - Yusia and Rob's Earth Moving.
22/Sep/2026 10:27 AM
Question:
Good morning REM are intending to respond to this tender,

Can we request extension of time for closing of tender of 7 days please ?

Answered on 22/Sep/2026 02:21 PM:


Robert, I will extend the tender for another 7 days so that you can get your submission in.

But this will be the last EOT.
22/Sep/2026 11:08 AM
Question:
I understand this tender closing date has changed few times. I would like to request a further EOT until Monday 28th, so I can fine tune my submission over the weekend. My apologies for the inconvenience this may cause.

Answered on 22/Sep/2026 02:22 PM:


Daryl, I have agreed to extend for another 7 days.

But this will have to be the last EOT.
29/Sep/2026 02:45 PM
Question:
Hi Steve,

Apologies as I know you have extended this tender multiple times but our designers are still working to develop a plan to ensure the project can be delivered in line with Council's needs, and have requested more time.

If possible, we would like to request an additional 2 week extension to the tender period to allow this activity to be completed and a proposal to be assembled.

Thank you

Answered on 29/Sep/2026 02:48 PM:


In the interest of getting this right, I will allow a 2 week extension. Apologies to anyone who has already submitted a tender.

29/Sep/2026 02:53 PM
Sorry for the late notice.

I have decided to give everyone more time on this one.

It is a tricky one, given that we are so remote and people haven't had a chance to visit the site.

Thaks for your patience.
