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

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): The objective is to increase capacity of the plant to 6,000EP.

Questions asked by the buyer:

What experience have you had with this type of construction?

Do you have sufficient capacity to deliver this project prior to October 2027?

Please provide at least one Referee that would be relevant to this type of construction.

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.

Before you bid on this tender

A quick checklist to help you decide whether to bid and prepare a compliant submission for this water & environment opportunity. Always verify the details on the official source.

  • Confirm the exact closing date and time (and time zone) on the official portal — deadlines are strict and can be revised by a corrigendum.
  • Read the full notice and every attached document, including the scope, specifications and any bill of quantities or terms of reference.
  • Check the eligibility criteria — prior similar experience, annual turnover, certifications and registrations — and make sure you qualify before investing effort.
  • Prepare any earnest-money deposit (EMD) or bid security and the required formats early; missing or wrongly-formatted documents are a common cause of rejection.
  • Note how bids must be submitted (online or physical), in what format, and whether a digital signature or portal registration is required.
  • Watch for corrigenda and clarifications right up to the deadline — requirements and dates can change.
