SCOPE OF WORKS/SPECIFICATIONS (SOW)

Laramba is a remote community located about 205 km north-west of Alice Springs in the Anmatjere Ward, with a population of approximately 275 people. To get there, travel 122 km north along the Stuart Highway from Alice Springs, then turn left onto Napperby Station Road. The community is situated 83 km down this unsealed road, and you’ll know you’re nearby when you see the large metal camel sculpture.

This project consists of the supply and installation of one hard-cover shade structure with concrete flooring at Laramba. The new shade structure will replace the existing small shade shelter and must match the size of the existing large shade structure, approximately 6.3 m × 6.3 m (the contractor must confirm these dimensions on site before ordering any materials). The existing small shade structure, approximately 3.2 m × 4.6 m, is to be demolished and disposed of.

The new shade structure must include a concrete floor that matches the size of the structure and is at least 100 mm thick. The roof of the new structure should connect to or overlap with the existing structure’s roof to prevent rainwater from falling between them. The contractor must verify the required materials, roof type, and all necessary measurements on-site before ordering any materials. All works must comply with the National Construction Code (NCC) and all relevant Australian Standards.

A new 60,000-litre rainwater tank is also to be installed to collect water from both the existing and the new shade structures. The works must include all necessary guttering, downpipes, roof connections, and any fittings required to ensure proper rainwater collection into the tank.

The design arrangement can be adjusted according to the Section 40 certification requirements; however, the minimum sizing must remain the same as the existing large shade structure.

The contractor is to allow for all mobilisation and demobilisation costs, including transport, an initial site visit to confirm measurements and site conditions, travel, accommodation, machinery hire, personnel hire, and ongoing administrative costs.

The contractor is to allow for stakeholder engagement to confirm the design and finishes schedule before the commencement of works.

Preliminary works

• The contractor shall allow for all mobilisation and demobilisation costs, including the transportation of required personnel, equipment, machinery, and materials, as well as the management of all work health and safety obligations.

• Preparation for the commencement of works, including accommodation arrangements, travel logistics, and all associated administrative expenses.

• The contractor is to allow for an initial site visit within 2 weeks of contract award to confirm all necessary on-site details, including the existing dimensions of the large and small shade structures, roof types, roof heights, and any other site-specific information required before ordering any materials and commencing works.

• Site establishment, including setting up temporary facilities, services, and ensuring the site is fully prepared for construction activities.

• Rehabilitation of any areas disturbed as part of the construction works, ensuring the site is returned to an acceptable condition upon completion.

• The contractor is responsible for obtaining any necessary site access permits or clearances (note: the Sacred Site Clearance Certificate (SSCC) will be obtained by the principal (CDRC) prior to commencement of the work on site.

Site investigation and confirmation

• The contractor must carry out a site visit before ordering any materials.

• Accurately measure and record the dimensions and height of both the existing large shade structure (approx. 6.3 m × 6.3 m × 2.7 m eave height) and the existing small shade structure (approx. 3.2 m × 4.6 m).

• Identify the roof type, material, pitch, and overall construction materials of both structures, including footing or foundation details, as well as any other site-specific elements relevant to the construction.

• Evaluate how the new shade structure can be effectively joined to or overlapped with the existing large structure to prevent rainwater from falling between them.

Please note: The above dimensions of the existing large shade structure (approximately 6.3 m × 6.3 m × 2.7 m eave height are approximate only and must be confirmed on-site before ordering any materials.

If there are any changes in the actual dimensions, the contractor must notify the principal (CDRC) in writing.

Demolition of Existing Small Shade Structure

• Safely demolish and dispose of the existing small shade structure (approx. 3.2 m × 4.6 m).

• Remove all associated footings or slabs, if any.

• Clear the prepare the area for new construction as required.

Supply and Installation of 1 x hard cover new shade structure.

• Supply and install a new hard-cover shade structure in the same location as the demolished small shade structure, ensuring it matches the size of the existing large shade structure (approx. 6.3 m × 6.3 m

× 2.7 m eave height), as confirmed on-site.

• Fabricate and install steel posts and framing, hot-dip galvanised, to provide adequate structural support in accordance with the National Construction Code and all applicable Australian Standards.

• Install a new roof that connects to or overlaps with the roof of the existing large shade structure to prevent water ingress.

• Select and install roofing materials that are compatible in profile and appearance with the existing large shade structure. The contractor must confirm material compatibility on-site. The roofing material should comply with the National Construction Code and relevant Australian Standards and offer a costeffective and durable solution for CDRC.

• Install all required flashing and waterproofing components to ensure no rainwater falls between the two structures (if required).

• All works, including materials and workmanship, must comply with AS 4100 – Steel Structures, and all other relevant Australian Standards and the National Construction Code (NCC).

• The contractor must allow for the principal to select the roof colour, to be confirmed upon award of the contract.

Concrete Works.

• Supply and install a concrete slab and associated footings beneath the new hard cover shade structure only, including all required formwork and reinforcement for both the slab and footings. Construction must be in accordance with engineering specifications, the National Construction Code, and all relevant Australian Standards.

• The concrete slab may be slightly larger than the dimensions of the new shade structure (approx. 6.3 m × 6.3 m), if required, in accordance with the National Construction Code and all relevant Australian Standards.

• The minimum thickness of the concrete slab is to be 100mm in accordance with the National Construction Code and all relevant Australian Standards.

Rainwater Harvesting System (Including 60,000L Tank Installation):

• Supply and install a complete rainwater harvesting system to collect stormwater from both the new and existing large shade structures.

• Install new gutters, downpipes, and any other required accessories on both the new and existing shade structures, ensuring proper fall and alignment to efficiently direct water into the rainwater tank.

• Include all necessary components, such as leaf guards, downpipe screens, first flush diverters, and any other accessories required to minimise debris and ensure clean water entry into the system.

• Supply and install one 60,000-litre rainwater tank suitable for outdoor use in remote NT conditions (Laramba Community). The tank must be made from ZINCALUME® steel and comply with the National Construction Code (NCC) and all applicable Australian Standards.

• Confirm the tank dimensions with the supplier prior to installation to ensure suitability for the site layout and base preparation.

• Construct a stable tank base, such as a compacted sand/crusher dust pad or reinforced concrete slab, in accordance with the manufacturer’s specifications and all applicable Australian Standards.

• Connect all downpipes to the tank inlet and install all required fittings, including a screened leaf basket, inlet strainer, mosquito-proof overflow, and outlet with an isolation valve.

• Ensure the tank overflow is directed to a safe and approved discharge location, such as a soakage trench or drainage point.

• All plumbing works must comply with the National Construction Code and all applicable Australian Standards. Upon completion, provide all relevant warranty documents, installation manuals, and maintenance instructions to the principal.
